H. left or right, a valve is inserted. A shut-off component is inserted into the other connecting piece. The height and length of the panel panels are completely disregarded; it is only necessary to ensure that the flow connection and the return connection are at a distance specified by the customer. The manufacture of the heating (cooling) body is facilitated because the connectors are easy to manufacture and handle. The fluid supply and discharge takes place via advantageously longitudinal connections which are connected to connecting pieces via a pipeline system. One of the connections is or can be connected to the pipe system with both connecting pieces. The pipeline, the connections and the connecting pieces can be prefabricated in the form of individual parts or a kit and the individual parts or this kit are connected to the panel plates, in particular welded. This results in simple manufacture of the piping system and an operationally reliable, tight connection to the respective connection.

Description, from the claims and the drawing.

Fig. 1 shows a plan view of a heating (cooling) body 1 according to the invention, which comprises two opposite panel plates 2, 3. Each of these panel plates 2, 3, as can be seen from Fig. 3, each have a lower collecting duct 18 or 38 and an upper collecting duct 6 or 7. A flow connection 19 and a return connection 20 lie in the longitudinal center of the heater - (Cooling) body 1. The distance between the flow connection 19 and the return connection 20 corresponds to the distance specified by the customer. The flow connection 19 and the return connection 20 are closer to the wall-side panel plate 3 than the front-side panel plate 2, since this is usually due to the on-site predetermined distance from the wall 39 of the on-site supply and return connection set, not shown, provided by the customer . The two lateral end areas of the opposite upper ones

Collection channels 6, 7 of the panel plates 2, 3 are connected to connecting pieces 4, 5. These connecting pieces 4, 5 are advantageously identical to one another and are suitable for accommodating a valve 28 or a shut-off component 25. Since the connecting pieces 4, 5, but at least the receiving areas for the valve 28 and the shut-off component 25 have the same structure and the insert dimensions of the valve 28 and the shut-off component 25 are the same, the valve 28 and the shut-off component 25 can be exchanged with one another as desired, so that the valve 28 can be installed left or right as desired; the shut-off component 25 is inserted into the other connecting piece 4, 5. Each connecting piece 4, 5 comprises a cross tube piece with tube pieces oriented perpendicularly or parallel to the panel plates 2, 3.

1, the pipe sections 11a, 11b of each cross pipe section are connected to the upper collecting channels 6, 7. The pipe sections 23, 24 of the cross pipe section running parallel to the panel plates 2, 3 are for receiving a

Valve insert 8 or a shut-off or sealing insert 15 is formed. The tube part 23 has an insert or receiving opening 33 for a valve insert 8, into which this

Valve insert 8 can be inserted or screwed in. The end area of the

Valve insert 8 is received by the pipe section 24 or by a socket 10 formed in this pipe section 24 or is mounted in the socket 10 with an O-ring 9 in a fluid-tight manner. Connected to the pipe section 24 or to the connection piece 10 is a pipe system 42, indicated only by dashed lines in FIG. 1 and extending from the connection 19, from which fluid can flow into the open end of the valve insert 8. Fluid flowing into the valve insert 8 can be regulated with a valve disc or cone 8a through an outlet opening 8b in the valve insert 8 into the interior 27 of the cross tube piece and from there via the connection openings 21, 22 into the upper collecting channels 6, 7. The control of the valve 28 takes place with the adjustable valve disc or cone 8a, which regulates the fluid flow through the valve insert 8 or the outlet through the outlet opening 8b. In the connecting piece 5, which advantageously shows the same basic structure as the connecting piece 4, a shut-off component 25 having a shut-off insert 15 is inserted. The end of the shut-off insert 15 received by the connector 10 and sealed with an O-ring 9 in the connector 10 has a fluid-tight end plate 15c, so that fluid from the connected pipeline 42 does not enter the interior 27 of the cross tube piece or the collecting channels 6, 7 can kick; furthermore, the shut-off insert 15 has no outlet opening, like the outlet opening 8b in the valve insert 8.

In order to give the shut-off component 25 the function of a venting component, it can be provided that the end of the shut-off insert 15 inserted into the socket 10 is an end (sealing) plate 15c which is provided with a through opening and which through opening is supported by a spindle 15a Sealing component 15d is closable. The sealing component 15d or the spindle 15a can be adjusted from the outside with an actuating device 15b. The shut-off component 15 has corresponding ventilation openings on its front side, through which the air penetrating the sealing plate 15c can escape. In principle, it is irrelevant whether the flow connection 19 or the return connection

20 is connected to the lower collecting duct 38 of the front panel plate 2 or to the lower collecting duct 18 of the panel plate 3 close to the wall. For reasons of heating technology and connection geometry, it is advantageous if the return connection 20 is connected to the lower collecting duct 18 of the panel plate 3 close to the wall. In this In this case, the flow connection 19, which can optionally be connected or welded to the panel plate 3 via a support or supporting part 49, is connected in a fluid-conducting manner to the pipeline 42. The pipeline 42 thus extends from the flow connection 19 between the front panel plate 2 and the panel plate 3 near the wall to the connecting pieces 4 and 5. If necessary, the pipeline 42 is welded to a panel plate 2, 3 for support at some points.

Since a valve component 28 is inserted in one of these connecting pieces and a shut-off component 25 is inserted in the other of these connecting pieces, the supplied fluid can only enter the upper collecting ducts 6, 7 of the two panel plates 2, 3 via one of these connecting pieces, and flows through the heating ducts 30 in the respective lower collecting channels 18, 38 and emerges from the lower collecting channel, to which the return connection 20 is connected via a connecting piece 149, through this connection 20. An overflow of the fluid between the lower collecting duct 38 of the front panel plate 2 into the lower collecting duct 18 of the panel plate 3 close to the wall is made possible by line pieces 44 connecting these two panel plates 2, 3 or the lower collecting ducts 18, 38. These line pieces 44 shown in FIG. 3 connect the lower collecting channels 18, 38 and are advantageously formed by T-pieces. The opposite ends of the T-pieces are welded to the respective collecting channels 18, 38; the third connecting piece 49 'of the line pieces 44 is closed with a sealing component 45. This outwardly projecting connection 49 'can also be used to connect the heating (cooling) body 1 according to the invention to fluid lines, in which case the connections 19, 20 are sealed.

It is also possible to use neither a valve 25 nor a shut-off component 28 in the connecting pieces 4, 5, but to use the pipe pieces 23 with the insertion openings 33 for the connection of fluid lines, so that four connections in connection with the connecting pieces 49 'of the line pieces 44 are optionally available for connecting the heating (cooling) body 1. For this reason, it is advantageous if it is provided that the connecting pieces 49 'of the line pieces 44 and the insert openings 33 of the pipe pieces 23 have the same connection dimensions, in particular are designed as ^ "connections. The flow connection 19 and the return connection 20 also have the same connection dimensions and are advantageously designed as ^ "connections. The radiator thus meets all the usual connection requirements.

For emptying the heating (cooling) body 44 emptying sleeves are welded into the lower collecting channels 18, 38 and / or in the line pieces. The flow connection 19 and the return connection 20 are at a mutual distance which corresponds to the distance between the connections provided by the customer. It is advantageously provided that the flow connection 19 and the return connection 20 are located in a plane 41 which runs parallel to the panel plates 2, 3. The plane 41, in which the connections 19, 20 are arranged, is closer to the panel plate 3 close to the wall than to the front panel plate 2.

As can be seen from Fig. 3, the piping system 42 is approximately U-shaped and has a lower, substantially horizontal base part or two pipe sections 42 "extending from the connector 19 on both sides and two pipe sections 42 'rising upwards, the open into the connecting pieces 4, 5.

Since most convector plates 43 are fastened to the inner surfaces of the panel plates 2, 3, the upwardly extending pipe sections 42 ′ of the pipeline 42 are arranged either between the bends of the convector plates 43, as shown in FIG. 5, or between the convector plates 43, as in FIG Fig. 6 is shown.

In order to be able to insert the pipe 42 into the bends of the convector sheets 43 or to take into account the limited space available, it can be provided that, starting at the flow connection 19 or at a certain distance therefrom, the lower pipe section 42 "of the pipe 42 is bent downward into the lower edge or end region of the panel plates 2, 3 and - as shown in broken lines in FIG. 3 - is bent into the upwardly directed pipe section 42 'of the pipeline 42 in a curvature K having a relatively large radius of curvature.

Furthermore, it must be taken into account that the connections 19, 20 are advantageously located closer to the panel plate 3 close to the wall, ie they are not located in the central plane of the heating (cooling) body parallel to the heating plates 2, 3. The connection points 10 of the pipeline 42 to the connecting pieces 4, 5, however, lie in the central plane of the heating (cooling) body 1. For this reason, the rising sections 42 'of the pipeline 42 must either lie on the bottom, near the wall or near the panel Section 42 "is inclined upwards towards the center or enclose an angle with the longitudinal center plane of the heating (cooling) body 1 or with the axis of the cross tube piece determined by the tube pieces 26, 27, around the prefabricated part made of the connecting pieces 4 , 5, the piping system 42 and the connections 19, 20 to be able to properly weld the existing component between the two panel plates 2, 3. The angle between the upward pipe section 42 'and a lengthwise direction through the heating (cooling) body 1 running center plane is mainly due to the length of the connecting pieces 4, 5 perpendicular to the panel plates 2, 3 and the height of the panel battens 2, 3. These parameters are taken into account when assembling or welding the U-shaped pipeline 42 to the connections 19, 20 and the connecting pieces 4, 5 for different types of radiators. As an alternative to forming an inclination of the pipe section 42 'leading upwards, it could also be provided that a bend 55 of the otherwise vertical, below, in the area of the lower collecting duct 18, or above, in the region of the connecting pieces 4, 5 or of the upper collecting duct 7 extending pipe section 42 ' is formed, with which the different distance of the nozzle 10 and the pipe sections 42 "from the panel plate 3 is compensated.

It can be seen in FIG. 7, which is a top view of a single-layer heating (cooling) body, that the upward pipe section 42 'from the lower pipe section 42 ", which runs near the panel plate 3, is inclined towards one into the connecting piece 4 or 5 leading pipe piece 51, which runs centrally in the heating (cooling) body 1 and runs parallel to the panel plates 2, 3. As already mentioned, instead of such an inclination, the pipe section 42 'could lead vertically upwards and a corresponding offset 55 either be provided in the area of the lower section 42 "or in the area of the pipe section 51. Such an offset 55 will advantageously take place below or above the provided convector sheets 43 in order to rule out handling difficulties with the pipeline 42 when the panel plates 2, 3 are connected to the connecting pieces 4, 5 or the connections 19, 20.

In FIG. 3, a schematic sectional side view of a connecting piece 5 and the pipe section 42 ′ leading to the top connected to it is schematically shown on the left as seen from the center of the radiator. The pipe section 42 'leading upwards runs essentially vertically and has in its lower end area a cranking area 55 or a bend which leads to the lower pipe section 42' which runs essentially horizontally or has the curvature K. The one-layer heating (cooling) body 1 according to FIG. 7 is constructed in the same way as the heating (cooling) body shown in FIG. 1. Only the panel plate 2, as shown in FIG. 1, is omitted and the pipe socket 26 of the two cross pipe pieces forming the connecting pieces 4, 5 is closed with a sealing component 52; furthermore, the panel plate 3 on the wall is now arranged on the front side according to FIG. The panel plate 3 forms the visible front of the heating (cooling) body 1; Suspension brackets 53 are at most attached to the back of the panel plate 3. All other features of the two-layer heating (cooling) body can be realized on the single-layer heating (cooling) body.

Fig. 4 shows an embodiment of a connection set comprising a flow connection 19 and a return connection 20, the return connection 20 via a connection component 50, which is optionally formed in one piece with the connection 20, with the flow connection 19 for reasons of stability or for Preservation of the connection geometry is connected, in particular welded. For reasons of space, it can be provided that the pipeline 42 is guided through the flow connection 19 and through the return connection 20 and is connected to the flow connection 19 via an inflow opening 48. The pipe 42 is tightly welded into the two connections; corresponding welds 54 are indicated with dots.

FIG. 4a shows an alternative to FIG. 4, in which the pipe 42 penetrates the connection 20 tightly and opens into the housing 19 'of the connection 19 or is welded in. The outgoing pipeline 42 is also welded into the housing 19 '.

2 shows the possibility of expanding a two-layer heating (cooling) body 1 with a further panel plate 47. On this panel plate 47 at the points at which the heating (cooling) body 1 shown in FIG. 2 below has the inserted connecting pieces 4, 5 or the connected line pieces 44, line pieces 46 are welded on, so that the upper one The collecting duct of the further panel plate 47 is connected to the upper collecting duct 7 of the panel plate 2 and the line pieces 46 connected to the lower collecting duct of the panel plate 47 are connected to the lower collecting duct 38 of the panel plate 2. The panel plates 2 and 47 are thus flowed through in parallel with the fluid fed through the pipe section 27 into the upper collecting duct 7 of the panel plate 2.

An advantageous embodiment of the invention provides that in the case of different plate spacings or with different thickness B heating (cooling) bodies 1 or with cross tube pieces having different lengths perpendicular to the panel plates 2, 3, the distance D of the panel plates 2, 3 parallel plane 41 of the flow connection 19 and the return connection 20 from the wall-side outer surface 145 or from the plane of the weld seam 40 is always selected to be the same size. This embodiment offers the possibility that regardless of a thickness B of the respective heating (cooling) body 1, the plane 41, in which the flow connection 19 and the return connection 20 are arranged, always the same distance from a fixed point Have panel plate 3 close to the wall. This fixed point can be the outer surface 145 of the panel plate near the wall or its weld fold 40 or the surface of the panel plate 3 remote from the wall. It is thereby achieved that regardless of the thickness B of the heating (cooling) body, the flow connection 19 and the return connection 20 have exactly the predetermined wall distance A of the on-site predetermined connections and the panel plate 3 close to the wall also has the desired wall distance .

It can be provided that in the case of panel plates 2, 3, which are provided with convector sheets 43 on their inside, a recess 161 is formed in the convector sheet 43 in the region of the curvature K of the pipeline 42 to the section 42 'leading upwards To be able to form a larger radius of curvature. The upper and lower end regions of a convector plate 43 are designated 43 ". A recess 161 is hatched in FIG. 3, according to which any convector plate 43 that may be present is excluded, in order to create a space free of convector plates for guiding the pipeline 42, if necessary to be able to form the curvature K of the pipeline 42 with a correspondingly larger radius of curvature, which makes their manufacture easier.

In the same way as described for the lower region of the pipeline 42, the bends of the section 42 'of the pipeline 42 leading upwards can also be made in the Area in which this section 42 ′ merges into the connecting pieces 4, 5. Here too there is the problem of forming the largest possible radii in order to be able to bend the pipeline 42 more easily.

8 shows a view of a panel plate 3 close to the wall. The flow connection 19 is connected to a multi-part U-shaped piping system 42, which has a horizontally extending base section above the connections 19 and 20, comprising two pipe sections 42 ", which is on the side of the two connections 19 , 20 has a downward bend 72, so that the pipe sections 42 "running horizontally or parallel to the longitudinal edge of the heating plate 3 are set lower or run at a distance from the lower end region 43 'of the provided convector sheets 43. In the present case, the two horizontally running pipe sections 42 ″ are connected to the upwardly running pipe sections 42 ′ via a connection point 70; this pressure welding connection 70 is shown in more detail in section A in detail. This pressure welding connection 70 is produced immediately before the U-shaped piping system is installed 42 is completed on the heating panel 3. This simplifies the storage of the U-shaped pipeline 42 since, apart from the connecting pieces 4, 5 and the connections 19, 20, only relatively short pipe sections 42 ′ and 42 ″ need to be kept in stock. Instead of pressure welding connections, squeeze, adhesive or screw connections can also be formed. In Fig. 8a it can be seen that the two extending to the side

Pipe sections 42 "each have a bend 71 which extends essentially horizontally in order to displace the connecting end 73 of the pipe section 42" into the central plane of the heating (cooling) body 1. In this case, the pipe sections 42 ′ extend vertically upward to the pipe end 53 or to the connecting piece 10 in the pipe socket 24 of the connecting piece 4 or 5 designed as a cross pipe piece.

In Fig. 8b, the two pipe sections 42 "run parallel to the heating panel 3 to the connection point 70. The pipe section 42 'extending upwards to the center 10 between the panel plates 2, 3 is in this case inclined at an acute angle to the central plane of the heat sink With a corresponding design of the pipe sections 42 ', it is sufficient to use a single one

To produce pipe section 42 ', since this is suitable both for connection to a connecting piece 4 and to a connecting piece 5, because the pipe sections 42' are mirror images of the same or can be constructed identically. In particular, the connection points 70 lie symmetrically to a central plane perpendicular to the panel plates 2, 3. Pipe sections 42 ', which have an offset 55 or bend in their course in order to compensate for the different distance between the connections 19 and 20 and the connections of the connecting pieces 4, 5 from a heating panel 2, 3, have previously been constructed in mirror image, but can be mutually exclusive not be mixed up; in this case there are always two pipe sections 42 ′ bent in this way to be produced and connected. In Fig. 8 above it is indicated that a regulating valve can be used both in the connecting piece 4 and in the connecting piece 5.

In Fig. 9, a U-shaped pipe system 42 is shown, which is also constructed in several parts. A horizontally extending distributor pipe 62 is connected to the connection 19 and has connections 60 and 61. A conventional pipe section 42 ″ can be connected to these connections 60 and 61 by conventional connection techniques, at the end 73 of which the pipe section 42 ′ leading upwards is connected in the connection point 70. The pipe system 42 thus consists of a total of five parts, one of which Part of the distributor piece 62. The pipe sections 42 ″ and the pipe sections 42 ′ can each be constructed identically to one another. Advantageously, the pipe sections 42 "are of the same length, so that they can optionally be connected to the connections 60, 61 for connecting them to the pipe sections 42 '.

In principle, it is possible that only a single pipe section 42 "is provided. This pipe connection can be removed and installed and connected to the connections 60, 61 or the connection points 70, for example with sealing kits and union nuts. This one pipe section 42" is connected to that pipe section 42 'connected, which leads to the connector 4 or 5, in which the valve 28 is inserted. Since a shut-off component 25 is inserted in the respective other connecting piece, it is not necessary to connect a pipe section 42 'to the pipe section 42' leading to this connecting piece. The respective distributor connection 60 or 61 is sealed in this case. If the valve 28 is to be transferred from the connecting piece 5 into the connecting piece 4, the pipe section 42 "is removed and installed in the left-hand radiator region in Fig. 9. As shown in Fig. 9a, the pipe sections 42 'run from a lower layer close to the panel plate to that Connection piece 10, which is located in the middle plane between the two panel plates 2, 3. As shown in Fig. 9b, in this embodiment of a piping system 42, the distributor pipe 62 can be bent downward by forming bends 72, so that the connections 60, 61 are lower so that the horizontal pipe sections 42 ″ can be better guided past the convector plates 43.

10 shows an embodiment of a heating (cooling) body, in which an integral U-shaped pipe system 42 is provided, which is connected to the connection 19. The other connection 20 is connected via a connecting line 64 to a connecting part 44, in particular a T-piece or cross-pipe piece, provided in the lateral end region of the heat sink and connecting the two lower, opposite collecting ducts 18, 38 of two panel plates 2, 3. Since the connections 19, 20 are arranged closer to the wall-side panel plate 3, the connecting line 64 is provided with a corresponding horizontal bend 74 or offset 75. The Bending takes into account a horizontal offset between the connections 19, 20 and the connection of the connecting part 44; the bend or offset 75 takes into account a vertical displacement of the connecting line 64 and the connecting part 44.

FIG. 11 shows in section and FIG. 11a a top view of a heating (cooling) body in which the multi-part piping system 42 has a horizontal base part, comprising the pipe section 42 ″ lying on both sides of the connections 19, 20, and an upwards on both sides extending vertical pipe section 42 '. At a connection point 70, at least one of the horizontal pipe sections 42 "is connected to a connecting component 65, which in turn is connected in a fluid-conducting manner to the upwardly extending pipe section 42'. The connecting component 65 is not connected in a fluid-conducting manner to the connecting part 44, in particular welded to it, the latter being able to be formed by a T-piece or cross-tube piece. In this way, a variety of connection options for the heating (cooling) body 1 is achieved without losing the possibility of optionally inserting valve bodies 28 or sealing components 25 into the two connecting pieces 4, 5 above. In the illustrated case, the horizontal pipe sections 42 "run between the connections 19 and 20 and the panel plate 3 and are bent toward the central plane of the heating (cooling) body at 71 to the connecting component 65. The connecting piece 65 lies below the provided convector plates, the spatial extension of which 12 shows a schematic section of an embodiment of a connecting piece 4 or 5, a T-piece 76 connecting the two panel plates 2, 3, which takes the place of a cross tube piece, connects to the two opposite tube pieces 11a, 11b the two parallel panel plates 2, 3. The middle tube piece 23 of the T-piece 76 forms a receptacle for a valve housing 83 for a valve insert 28. The valve housing 83 is screwed into the connection 23 into the indicated thread 33. 79 are seals for Seal the valve housing 83, the nozzle 23 and the valve insert 28 denote An outflow opening 81 can be opened or closed with the valve insert 28. The connector 10 or the pipe section 42 'opens into the connector 23. When the valve insert 28 is open, the fluid can flow from the connector 10 or the pipe section 42' via the opening 82 in the valve housing 83 and the opening 81 into the interior 27 of the T- Piece 76 and from there flow into the panel plates 2, 3.

Instead of the valve insert 28 or the housing 83, a sealing component 25 can also be screwed into the thread 80 of the socket 23, with which the opening 81 ′ in the socket 23 is sealed. 13, 13a, 13b and 13c are different embodiments of

Shut-off components 25 shown in combination with ventilation components 15, as they can be used in the connecting pieces 4, 5. In the connecting piece 10 of the cross-piece piece forming the connecting piece 4, 5, a shut-off component 25 in the form of a sealing washer is inserted with a seal 90. The shut-off component 25 is according to Fig. 13 hooked or latched to the ventilation component 15 via a bolt 91. The venting component 15 has a spindle 15b which closes a vent opening 92; With a corresponding square extension part 93, the vent spindle 15b can be adjusted in a thread 93 in order to open or close the vent opening 92. The venting component 15 and the shut-off component 25 are coupled to corresponding coupling devices 94 which allow air to pass through or, when the venting component 15 is screwed in, is displaced into a thread 95 in the pipe section 23 of the sealing component 25 into the connector 10 and seals it. When the ventilation component 15 is unscrewed and removed, the sealing component 25 is simultaneously pulled out of the connecting piece 4, 5.

In the embodiment according to FIG. 13a, the sealing component 25 with a screw part 96 having air passage openings 96 'is screwed into a thread 97 in the pipe socket 23 and can be screwed into or removed from the connecting piece 4, 5 independently. The venting component 15 is essentially constructed like the venting component 15 according to FIG. 13; however, there is no coupling or connection to the sealing component 25. The sealing component 25 can e.g. with an Allen key, which is inserted into a recess 98, rotated and adjusted in the thread 95.

13b shows an embodiment in which the sealing component 25 is coupled to the ventilation component 15. The bolt 91 carrying the sealing component 25 is connected to the ventilation component 15 via a latching or plug-in connection 91 'and can be inserted into and removed from the connector 10 when the ventilation component 15 is rotated. In this embodiment, the vent 92 is exposed.

13c shows an embodiment of a sealing component 25 which is coupled to the ventilation component 15 via a tube part 86. Air can enter a pipe part 86 via an inflow opening 87; the tube part 86 communicates with the vent opening 92, which can be closed with the vent spindle 15b.

All of the designs made for heating (cooling) bodies formed by two panel plates 2, 3 also apply to heating (cooling) bodies which have only a single panel plate 3. The fluid flow direction through the heating (cooling) body can be chosen arbitrarily, advantageously the connection 19 is the flow connection for thermal reasons.

In all embodiments of the heat sink according to the invention, it is possible for the return connection 20 arranged in the central longitudinal region of the heating (cooling) body 1 to be connected in a fluid-conducting manner to the central longitudinal region of the lower collecting duct 18 of at least one panel plate 2, 3. Such a connection variant for one of the two connections 19, 20 is shown in FIGS. 14 and 14a. The connection of this connection 20 to the lower collecting duct 18 takes place essentially somewhat outside the longitudinal center of the heating (cooling) body 1. Here, as provided in FIG. 14 a, the connection 20 can be connected to the collecting duct 18 via a connecting piece 103 be fluidly connected. Such a connection is made in particular by resistance pressure welding.

In such an embodiment e.g. the connecting line 34 shown in Fig. 10a is omitted. Such a connection of the return connection to the central region of the lower collecting duct 18 is also shown in FIGS. 8a and 9a.

A preferred embodiment of a heating (cooling) body according to the preamble of claim 31 is characterized according to the invention by the features of the characterizing part of claim 31. It is advantageously provided in such a radiator that the

Distribution piece 100 is connected directly to the connection 19, 20, preferably flow connection 19, or is arranged between this connection 19, 20 and the level of the two connecting pieces 4, 5.

From Fig. 14 it can be seen that the distributor piece 100 is between a minimum lower height, in which it abuts or fastens to the connection 19, in particular welded, and a maximum height, in which the outgoing from the distributor piece 100 on both sides Connection lines 101, 102 are horizontal, can be varied in terms of its height. In Fig. 14, a distributor 100 is shown in dashed lines, which is located in the lower quarter of the radiator height and from which the connecting lines 101, 102 shown in dashed lines go to the connecting pieces 4 and 5 respectively. In this case, the distributor piece 100 is Y-shaped. In the case in which the connecting lines 101, 102 run horizontally between the distributor piece 100 and the connecting pieces 4 and 5, the distributor piece 100 is a T-piece.

This embodiment is very simple since the position of the distributor piece 100 can be varied as required and the embodiment of the heating (cooling) body. Furthermore, the distributor piece 100 with the connections 19 and 20 could be made in one piece, as a result of which a compact structural unit is created and the pipeline 142 is omitted. This unit can be connected directly to the lower collecting duct 18, 38 or is simply connected to the connecting pieces 4 and 5 via the connecting lines 101 and 102. A very simple solution with regard to the connection geometry in combination with a return connection 20 connected to at least one of the two lower collecting channels 18, 38 results according to the embodiment shown in FIG. 14, in which the distributor piece 100 is at the level of the two connecting pieces 4 and 5 lies. Instead of providing a manifold 100 in the form of a T-piece, as detailed

B is shown, the distributor piece can also be designed in the form of a tube piece 100 ', as shown in detail B1. In this case, the ascending pipeline 142 is welded into the wall of the pipe section 100 '. In detail B2 is in a one-piece continuous pipe connecting the connecting pieces 4 and 5 with pipe sections 101 and 102 in the area of

Pipeline 142 formed a pinch 200, in the area, the pipe 142 is welded. In this case, the pipes 101 and 102 can have a horizontal or a V-shaped course.

Another possibility for connecting the pipes 101 and 102 to the

Pipeline 142 is shown in detail B3. At the end of the ascending pipeline 142, which has a pinch 200 for the defined formation of connections, the pipelines 101 and 102 are welded on both sides. Such welding is advantageously carried out by resistance pressure welding.

15 shows a radiator in which precautions are taken to suppress or absorb thermal stresses in the pipes of the heating (cooling) body according to the invention. These precautions can be implemented in all pipelines in which undesirable thermal stresses can affect the stability of the radiator. A detail D shows that the pipeline, in this case the pipeline 101, is divided into partial areas. A compression or bruise 201 is formed in the respective end regions of these subregions; the tube ends are further welded to one another, as indicated at 202, in particular by resistance pressure welding. If the pipeline 101 is now extended or shortened compared to the panel plate 2, 3 by different fluid temperatures, the bruises 201 in the pipe walls of the line 101 have a compensating effect.

It is possible to provide several such bruises in the pipes.

Such a configuration is particularly advantageous for the horizontally running pipelines 101 and 102, since these pipelines end in the connecting pieces 4 and 5 welded firmly into the radiator panel.

In principle, it is possible in the pipelines 101 and 102 and also in the pipeline

142 corresponding offsets, turns or the like. to train, e.g. 15 with

E are indicated. Such turns are also the same length changes due to

Temperature fluctuations. In particular, such arrangements are also advantageous for a pipeline 64, as shown in FIG. 10.

The detail D shown in FIG. 15 corresponds approximately to a metallic expansion bellows; in principle, expansion bellows made of metal could be inserted or welded into the pipelines 101, 102, 64 and in other thermally stressed pipelines in order to accommodate changes in length. An advantageous connection geometry is obtained when the connections 49

Are terminal formed - lead pieces 44 and the insertion holes 33 for receiving a valve insert 8 or a Absperreinsatzes 15 than _^1/2 "connection and / or the flow connection 19 and the return terminal 20 as a _^1/2" or ^ '' . In terms of heat technology and production, it is advantageous if the width of the base part of the U-shaped Pipe system 42 or its extension in the longitudinal direction of the panel plates 2, 3 is between 30% to 97%, preferably between 70% to 97% of the length of the heating (cooling) body 1. There are advantageous dimensions.

To compensate for stresses due to thermal expansion, it is also possible to provide sleeves 301 with seals 300 on the connecting pieces 4, 5 and / or the connections 19, 20 directly or via connecting supports (FIG. 16), in particular by welding or molding, into which the Pipes 42, 42 ', 42 "; 101, 102, 142, etc. can be plugged in tightly; movements of the pipes relative to the connecting pieces are thus possible. When screwing in the screw part 302, the seals 300 are crimped with a screw part 302 and seal the pipe It is also possible to connect such sleeves to the distributor piece 100 and / or the T pieces 44.

The pipe lines provided or mentioned above can also have screwed sockets 303 in their course by dividing the pipe parts pipe parts 101 'or 102' (FIG. 17) and forming a thread 304 at one end of the one pipe part 101 'onto which a screw part 303 can be screwed on, which squeezes the seal 300 and presses against the end of the pipe part 101 'and against the outer surface of the inserted pipe part 101 ". Such sockets or screw sockets are known in principle from the sanitary or water pipe installation. FIG. 18 shows the movable connection of pipe parts 101 'and 102' with a

Sealing sleeve 306 with seals 300 which seal the tubular parts against one another in a movable manner.
