Description

A kind of novel advection line condenser

Technical field

The utility model discloses a kind of novel advection line condenser.

Background technology

The air conditioning for automobiles heat exchanger comprises evaporimeter and condenser two big major parts, present condenser both domestic and external generally adopts the parallel flow type condenser, its function is that the high-temperature gas refrigerant of compressor of air conditioner output is passed to outer fin heat radiation by the condenser tube wall, heat is dispersed in the outside air and goes, and makes refrigerant change normal temperature high voltage liquid into by the HTHP gaseous state.And the flat tube of many checkerwork cells arranged in the middle of at present refrigerant passage normally adopts on the market the parallel flow type condenser, be commonly called as harmonica-shaped tube, extrusion forming process is often adopted in the production of harmonica-shaped tube, and its shape is as (shown in Figure 2), and because the restriction of processing technology, its general wall thickness is about 0.5mm, wall thickness can not be made thinner, however in calorifics heat transfer coefficient η, under equal condition, heat transfer coefficient and material wall thickness δ are inversely proportional to, be η ∝ 1/ δ, when δ is thin more, η is just big more, heat transfer speed is just fast more, heat-exchange capacity is just high more, and it is thick more to work as δ on the contrary, and η is just more little, heat transfer speed is just slow more, and heat-exchange capacity is just low more.Hence one can see that, and at present traditional harmonica-shaped tube is owing to the restriction of processing technology self, and its tube wall can not be made thinner, and the efficient that has hindered hot transmission heat radiation to a great extent improves.

Summary of the invention

The utility model is at the problems referred to above weak point, and a kind of simple in structure, manufacturing is easy to process and heat exchanger effectiveness is high a kind of novel advection line condenser is provided.

In order to achieve the above object, the utility model is by the following technical solutions:

A kind of novel advection line condenser comprises some groups of flat tubes and some outer fins that is connected between adjacent flat tube, and described flat tube is made up of a socket and the bending inner fin be located in the socket.

Above-mentioned socket is a La Zhashi socket, and the height in the middle of its cross section is slightly higher than both sides height.

Now the utility model is described in further detail with specific embodiment in conjunction with the accompanying drawings:

The specific embodiment

As shown in Figure 1, a kind of novel advection line condenser 1 described in the utility model, comprise dividing plate 15, two end-plates 16, some groups of flat tubes 11 and some outer fins 12 that is connected in 11 of adjacent flat tubes in collector tube 13, following collector tube 14, the collector tube, as shown in Figure 3, above-mentioned flat tube 11 comprises a La Zhashi socket 111 and is located at the interior bending inner fin 112 of socket, bending inner fin 112 is welded on the inwall of La Zhashi socket 111, bend inner fin 112 for convenience and pack in the pipe, the height in the middle of La Zhashi socket 111 its cross sections is slightly higher than both sides height.

Further above-mentioned bending inner fin 112 cross sections are zigzag (as shown in Figure 5), or it is waveform (as shown in Figure 6), or it is square waveform (as shown in Figure 7), and described bending inner fin 112 can also be provided with through hole 1121 (as shown in Figure 4) in the bending side, or and be provided with protruding position (not drawing among the figure), the through hole that described through hole 1121 can have any shape, can be circular hole, or be square hole, or be elliptical aperture, or be star-shaped aperture, and described protruding position also can be the protruding position of arbitrary shape, can be cylindric protruding position, or the protruding position of flat column, or be the protruding position of oval column, or be the protruding position of star column, or be the spherical protruding position of semicircle; Through hole 1121 and protruding potential energy increase the upset of passage to the refrigerant fluid, and it is higher to make its heat transmit more even efficient.Bending inner fin 112 also can not established through hole and protruding position.

Present condenser both domestic and external generally adopts the parallel flow type condenser, its function is that the high-temperature gas refrigerant of compressor of air conditioner output is passed to outer fin fin by the condenser tube wall, heat is dispersed in the outside air and goes, and makes refrigerant change normal temperature high voltage liquid into by the HTHP gaseous state.And the flat tube of many checkerwork cells arranged in the middle of at present refrigerant passage normally adopts on the market the parallel flow type condenser, be commonly called as harmonica-shaped tube, extrusion forming process is often adopted in the production of harmonica-shaped tube, its shape is as (shown in Figure 2), and because the restriction of processing technology, its general wall thickness is about 0.5mm, and wall thickness can not be made thinner.And parallel flow type condenser of the present utility model adopts knockdown flat tube, it comprises a La Zhashi socket and the bending inner fin of packing in socket, the La Zhashi socket can adopt the two sides of 0.3mm to be with (composite plate that scolder is promptly arranged in Asia, aluflex sheet two sides) volume to be bundled into type again entirely, joining place is located at by the side, and it adopts the form of overlapping welding edge sealing, the bending inner fin adopts aluflex to roll and forms, and its cross section of stove postwelding as shown in Figure 3.During production up and down the dividing plate in collector tube, the collector tube, two end-plates, adorn assemblings such as the flat tube of bending inner fin and outer fin after, go into slice together and weld and form (as shown in Figure 1).It is about 20% that parallel flow type condenser of the present utility model adopts behind the said structure heat-exchange capacity to improve than tradition, and it is as follows that its heat-exchange capacity improves reason:

1. the tube wall of flat tube reduces to 0.3mm.And traditional flat tube thickness of pipe wall is 0.5mm at present, in its contrast wall thickness reduction 40%.Heat transfer coefficient η in calorifics, under equal condition, heat transfer coefficient and material wall thickness δ are inversely proportional to, i.e. η ∝ 1/ δ.When δ is thin more, η is just big more, and heat transfer speed is just fast more, and heat-exchange capacity is just high more.

2. because this flat tube configuration adopts the bending inner fin of packing in pipe.Make area of dissipation increase by 50%～60% in the pipe, manage the inner bending inner fin simultaneously and can also offer through hole in the bending side, fully multilated of gas in the pipe, high-temperature gas is by contacting with the bending inner fin, heat is in time passed to the flat tube inwall, pass to outer fin heat radiation by tube wall again, reach high efficiency heat exchange effect.

In sum, a kind of novel tie prevailing condensers described in the utility model is by the knot to flat tube The structure improvement design is compared with traditional condenser, and under the volume that is equal to, its heat-exchange capacity improves 20% About, under the prerequisite of the heat exchange amount that is equal to, consumptive material reduces by 20%, and namely weight reduces 20%, the volume phase Should reduce 20%, the efficient height, fuel consumption is corresponding reduction also.
