Definitions

  • the invention relates to a heat exchanger, in particular for a motor vehicle, comprising a heat transfer block, the first and second tubes, which are flowed through by a medium and flows around another medium, and at least one collecting device, wherein the first tubes in a first collecting area and the second tubes open into a second collecting region of the collecting device, wherein the first and the second tubes are arranged in two rows, which are arranged overlapping perpendicular to the direction of flow of the tubes.
  • a heat exchanger which comprises a collecting box which is divided into different collection box chambers.
  • a heat exchanger which comprises a series of short and a series of long tubes. The two rows of tubes are laterally offset from each other, that is not overlapping, arranged and open with their one ends in a collection box. With their other ends open the two rows of tubes in different collection facilities, in particular collecting tanks.
  • the object of the invention is to optimize the connection options in a heat exchanger according to the preamble of claim 1, in particular with regard to the space required.
  • the object is in a heat exchanger, in particular for a motor vehicle, having a heat transfer block, the first and second tubes, which are flowed through by a medium and flowed around by another medium, and with at least one collecting device, wherein the first tubes in a first collecting area and the second tubes open into a second collecting area of the collecting means, the first and the second tubes being arranged in two rows overlapping perpendicular to the straightening direction of the tubes, achieved in that the second tubes extend beyond the first collecting area to the first collecting area Second collecting area are extended, which is arranged offset in the flow direction of the tubes to the first collecting area.
  • the two rows of tubes can be arranged partially or completely overlapping.
  • a preferred embodiment of the heat exchanger is characterized in that the two rows of tubes are arranged completely overlapping perpendicular to the flow direction of the tubes. Preferably, the two rows of tubes are arranged offset in the direction of flow of the tubes.
  • a further preferred embodiment of the heat exchanger is characterized in that the two rows of tubes in the flow direction of the tubes are parallel to each other.
  • the individual tubes of the two rows of tubes are associated with each other in pairs.
  • Another preferred embodiment of the heat exchanger is characterized in that the two rows of tubes are flowed through in opposite directions from the medium.
  • the flow medium is supplied to the first tubes at their one ends.
  • the flow medium is then deflected into the second tubes, which are preferably parallel to the first tubes.
  • a further preferred exemplary embodiment of the heat exchanger is characterized in that a deflection device is provided at the ends of the tubes facing away from the collecting device, by means of which the medium is deflected from the first tubes into the second tubes.
  • the deflection can be designed as a separate collection box, but can also be integrally connected to the pipes.
  • a further preferred embodiment of the heat exchanger is characterized in that the collecting device has two connection points, which are arranged offset from one another parallel to the flow direction of the tubes. Preferably, the connection points are arranged directly above one another. This has proven to be particularly advantageous in terms of space.
  • a further preferred embodiment of the heat exchanger is characterized in that the collecting means comprises two connecting pieces, which run parallel to the flow direction of the tubes and are arranged parallel to the flow direction of the tubes offset from each other.
  • the connecting pieces allow the connection of pipes for the flow medium of the pipes.
  • the connecting pieces may be integrally connected to the collecting device or as separate parts with the collecting device.
  • a further preferred embodiment of the heat exchanger is characterized in that the collecting device comprises two separate collecting boxes, in particular collecting pipes, which are arranged offset in the flow direction and in the flow direction of the tubes to each other.
  • the collecting tanks, in particular collecting pipes extend transversely to the direction of flow of the pipes.
  • a further preferred exemplary embodiment of the heat exchanger is characterized in that the collecting device comprises a collecting box with a first collecting box chamber through which the second tubes extend into a second collecting box chamber.
  • each collection box chamber is assigned a connection point, in particular a connecting floor.
  • a further preferred embodiment of the heat exchanger is characterized in that the two Sammelkastenkammem are separated by a partition wall, through which extend the second tubes.
  • the partition wall extends transversely to the flow direction of the tubes.
  • the heat exchanger 1 comprises a heat transfer block 2 with first tubes 3, 4, which are arranged in a first row 5.
  • the first tubes 3, 4 serve to convey a medium, for example water, and are arranged parallel to one another in a direction x.
  • the direction x is also referred to as the flow direction of the tubes.
  • the first tubes 3, 4 are arranged in the first row 5 in a direction y next to each other. Perpendicular to the directions x, y extends a direction z, in which the tubes 3, 4 are surrounded by another medium, for example air.
  • the direction z is also referred to as Umstromungsraum of the tubes 3, 4.
  • Second tubes 6, 7 are arranged in a second row 8, which extends in the y-direction and is spaced in the z-direction from the first row 5.
  • the first tubes 3, 4 and the second tubes 6, 7 open at one end into a collecting device 10, which comprises a first collecting box 11 and a second collecting box 12.
  • the two header boxes 11, 12 are substantially in the form of headers, one end of which in each case a connecting piece 13, 14 is angled.
  • the connecting pieces 13, 14 are each integrally connected to the associated collection box 11, 12.
  • the second tubes 6, 7 in the x-direction, that is, in the flow direction of the tubes, extended beyond the first collection box 11 addition.
  • the second collection box 12 extends parallel to the first collection box 11.
  • the second collection box 12 is arranged offset in the positive x-direction and in the negative z-direction relative to the first collection box 11. Thereby it is possible that the two connecting pieces 13, 14 are arranged one above the other in the x-direction.
  • the ends of the first tubes 3, 4 facing away from the collecting device 10 are connected via a deflection device 18 to the associated ends of the second tubes 6, 7.
  • the deflecting device 18 comprises a plurality of pipe sections 15, 16, which are substantially U-shaped and in each case connect two associated ends of the two pipe rows 5, 8 with each other.
  • FIGS. 2 and 3 a section of a heat exchanger 21 with a heat transfer block 22 is shown in fragmentary detail in different views.
  • the heat transfer block 22 includes a plurality of first tubes 23, of which FIG. 2 only one tube is shown.
  • the tubes 23 are as in the FIG. 1 illustrated embodiment arranged in a first row 25.
  • a variety of second tubes 26, of which in FIG. 2 also only one is shown, are arranged in a second row 28 and parallel to the first tubes 23rd
  • the tubes 23, 26 open into a collecting device 30, which is subdivided by a dividing wall 36 into two different collecting chambers 31, 32.
  • the first tubes 23 of the first row of tubes 25 open into the first collection chamber 31.
  • the second tubes 26 of the second row 28 extend through the first collection chamber 31 and the partition 36 therethrough.
  • the partition 36 divides the two collection chambers 31, 32 within a common header 39. From the header 39 go out two connecting pieces 33, 34 which are arranged one above the other in the x-direction and extend in the z-direction.
