The heat exchanger (also called condenser) on the existing automobile is usually arranged at the air inlet near the head of the automobile and used for heat exchange of the refrigerant.
At present, in order to reduce wind resistance, the area of an air inlet of a new energy automobile is designed to be smaller, and is generally less than 1/3 of that of a fuel oil automobile. That is, on the premise that the vehicle body is designed to be streamline, the opening surface at the air inlet is smaller, so that the wind resistance during running is further reduced. The heat exchange efficiency of the heat exchanger is relatively reduced, but the performance requirement of the new energy vehicle type air conditioning system is not reduced, and meanwhile, the battery system is cooled due to the increase, so that the load of the heat exchanger is improved compared with that of the fuel vehicle. Because the area of the air inlet is reduced, the heat exchange effect of the heat exchanger is poor, and the air conditioning system is poor in refrigeration and heating, so that the comfort of the whole automobile is affected.
Aiming at the problems in the prior art, the utility model provides a heat exchanger, a new energy automobile heat pump system and a new energy automobile. The utility model provides a heat exchanger, which is characterized in that: the positive windward area is increased through the inclined arrangement of the flat tube on the heat exchanger, and the wind of the small opening surface at the air inlet is conveyed towards the direction of the large opening surface at the rear, so that the heat diffusion range is enlarged, and the heat exchange efficiency or performance is improved.

Wherein the heat exchanger 10 can be connected with various components in the new energy automobile 20 through pipelines, thereby forming a heat exchange loop. For example, the inlet of the heat exchanger 10 is connected to the outlet of the compressor, the outlet of the heat exchanger 10 is connected to the inlet of the evaporator, and the outlet of the evaporator is connected to the inlet of the compressor to form a heat exchange circuit.
According to the heat exchanger 10 provided by the embodiment of the utility model, the flat tube 300 obliquely arranged on the heat exchanger 10 increases the frontal area, and the wind of the small opening surface at the air inlet 30 is conveyed towards the rear large opening surface, so that the heat diffusion range is increased, and the efficiency or performance of the heat exchanger 10 is further improved.
The technical scheme of the utility model is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a schematic structural diagram of a heat exchanger according to an embodiment of the present utility model. FIG. 3 is a schematic view of the cross-section A-A of FIG. 2. Fig. 4 is a schematic view of a partial enlarged structure at B in fig. 3. Fig. 5 is a schematic view of a partial enlarged structure at C in fig. 3. The heat exchanger 10 provided by the embodiment of the utility model is applied to a new energy automobile 20, and referring to fig. 2, the heat exchanger 10 includes: the first header 100, the second header 200, the first flat tube group 300, and the second flat tube group 400. The first flat tube group 300 and the second flat tube group 400 are sequentially arranged along the upper portion of the first header 100 to the lower portion of the first header 100.
Referring to fig. 3 to 5, the first flat tube group 300 includes a plurality of first flat tubes 310, the second flat tube group 400 includes a plurality of second flat tubes 410, the first header 100 and the second header 200 are communicated through the first flat tubes 310, the first header 100 and the second header 200 are communicated through the second flat tubes 410, and the respective first flat tubes 310 and second flat tubes 410 are disposed at intervals along the extending direction of the first header 100 or the second header 200.
The first header 100 and the second header 200 may have hollow tubular structures, such as round tubes, square tubes, etc., for distributing and collecting the liquid or gaseous refrigerant. The first header 100 and the second header 200 may be disposed in parallel and vertically. Wherein an upper portion of at least one of the first header 100 and the second header 200 is for communication with a refrigerant supply pipe, and a lower portion of at least one is for communication with a refrigerant discharge pipe. Illustratively, as shown in fig. 2, a heat exchanger outlet 11 is provided at a lower portion of the first header 100, the heat exchanger outlet 11 being for communication with a refrigerant discharge pipe, and a heat exchanger inlet 12 is provided at an upper portion of the second header 200 for communication with a refrigerant supply pipe.
The plurality of first flat tubes 310 in the first flat tube group 300 may be disposed at intervals along the upper to lower direction of the first header 100 or the second header 200, and the extending direction of each first flat tube 310 may be disposed parallel to the horizontal plane. The second flat tube group 400 is located below the first flat tube group 300, and a plurality of second flat tubes 410 in the second flat tube group 400 may be disposed at intervals along the upper to lower direction of the first collecting pipe 100 or the second collecting pipe 200, and the extending direction of each second flat tube 410 may be parallel to the horizontal plane. In this way, a so-called parallel flow heat exchanger 10 is formed.
For example, the first flat tube 310 and the second flat tube 410 may be extruded from aluminum or an aluminum alloy material. The cross-sections of the first flat tube 310 and the second flat tube 410 may be in a long round shape or a rectangular shape, which is not shown in the drawings. The upper surfaces and the lower surfaces of the first flat tube 310 and the second flat tube 410 are flat surfaces. The outer dimensions of the first flat tube 310 and the second flat tube 410 may be set as appropriate in the range of 1.1 to 3.0mm in thickness and 6 to 20mm in width. The first flat tube 310 and the second flat tube 410 may be single-hole tubes having one refrigerant flow path therein, or may be porous tubes having a plurality of refrigerant flow paths. The number of refrigerant channels in the porous tube may be, for example, 4 to 10, and the number of specific channels is not limited.
In the embodiment of the present application, the first header 100 and the second header 200 are communicated through the first flat tube 310. In this way, the refrigerant may flow from the first header 100 to the second header 200 through the first flat tube 310, or may flow from the second header 200 to the first header 100 through the first flat tube 310. The first header 100 and the second header 200 are in communication via a second flat tube 410. In this way, the refrigerant may flow from the first header 100 to the second header 200 through the second flat tube 410, or may flow from the second header 200 to the first header 100 through the second flat tube 410.
Specifically, the high-temperature and high-pressure refrigerant supplied from the refrigerant supply pipe flows into the second header 200 through the heat exchanger inlet 12, is distributed to the first flat tube group 300 and the second flat tube group 400, flows into the first header 100 through the first flat tube 310 and the second flat tube 410, respectively, and is discharged through the refrigerant discharge pipe through the heat exchanger outlet 11 for the subsequent evaporator.
It should be noted that, in order to increase the flow path of the refrigerant flowing through the heat exchanger 10, a first diverting portion may be provided in the first header 100, and a second diverting portion may be provided in the second header 200. In this way, the high-temperature and high-pressure refrigerant supplied from the refrigerant supply pipe flows into the upper portion of the second header 200 through the heat exchanger inlet 12, is distributed to the upper portion first flat pipe 310 of the first flat pipe group 300, flows through the upper portion first flat pipe 310 into the first diverting portion of the upper portion of the first header 100, is distributed to the lower portion first flat pipe 310 of the first flat pipe group 300, flows in the direction in which the refrigerant flows in the lower portion first flat pipe 310 is reversed to the direction in which the refrigerant flows in the upper portion first flat pipe 310, and thereafter, the refrigerant is returned to the lower portion of the second header 200, is diverted again to the second flat pipe 410 distributed to the second flat pipe group 400 by the second diverting portion, flows from the second flat pipe 410 to the lower portion of the first header 100, and is discharged through the refrigerant discharge pipe 11 for use by the evaporator. That is, the so-called three-flow design, the refrigerant flows in a serpentine path in the heat exchanger 10 to increase the heat exchange stroke, so that the refrigerant can obtain more sufficient heat exchange, and the effect is better.
Of course, more flows are also possible, i.e. more first diverting portions in the first header 100 and more second diverting portions in the second header 200. In this way, the refrigerant can exchange heat more fully in the heat exchanger 10.
Each first flat tube 310 is obliquely arranged towards the upper part of the first collecting pipe 100, and a first heat exchange air channel 320 is formed between two adjacent first flat tubes 310; a second heat exchanging air duct 420 is formed between two adjacent second flat tubes 410. With continued reference to fig. 3, the parallel arrows represent the wind direction at the air inlet 30, and each of the first flat tubes 310 is inclined in the direction from the head to the tail and upward. Thus, the first flat tube 310, which is disposed obliquely, increases the frontal area and the heat exchanging surface is larger than the flat tube disposed in parallel with the horizontal plane. Moreover, it can be appreciated that when the air at the air inlet 30 passes through the first heat exchange air duct 320 and the second heat exchange air duct 420, the air is guided and conveyed towards the direction of the larger rear opening surface, so that the heat diffusion range is enlarged, the wind resistance is reduced to a certain extent, the air flow is accelerated, the air inlet quantity is improved to a certain extent, and the overall heat exchange efficiency or performance of the heat exchanger 10 is further improved.
In addition, since the first flat tube 310 is of an inclined design, the inclined first flat tube 310 tends to increase in width, the heat exchange area is further increased, and the heat exchange performance is further improved on the premise that the diameters of the collecting pipes are the same or the distances (i.e., thicknesses) between the front and rear of the flat tubes of the heat exchanger 10 are the same. For example, the width of the flat tube parallel to the horizontal plane is 16mm, and the width of the first flat tube 310 varies from 16.4mm to 17.0mm when the angle is in the range of 13 ° to 20 ° depending on the angle with the horizontal plane.
The heat exchanger 10 provided by the utility model is applied to a new energy automobile 20. The heat exchanger 10 includes: the first header 100, the second header 200, the first flat tube group 300, and the second flat tube group 400. The first flat tube group 300 and the second flat tube group 400 are sequentially arranged along the upper portion of the first collecting pipe 100 to the lower portion of the first collecting pipe 100; the first flat tube group 300 includes a plurality of first flat tubes 310, the second flat tube group 400 includes a plurality of second flat tubes 410, the first header 100 and the second header 200 are communicated through the first flat tubes 310, the first header 100 and the second header 200 are communicated through the second flat tubes 410, and the first flat tubes 310 and the second flat tubes 410 are arranged at intervals along the extending direction of the first header 100 or the second header 200; each first flat tube 310 is obliquely arranged towards the upper part of the first collecting pipe 100, and a first heat exchange air channel 320 is formed between two adjacent first flat tubes 310; a second heat exchanging air duct 420 is formed between two adjacent second flat tubes 410. Therefore, the inclined arrangement of the flat tube on the heat exchanger 10 increases the frontal windward area, and conveys the wind of the small opening surface at the air inlet 30 towards the direction of the large opening surface at the rear, thereby increasing the heat diffusion range and further improving the heat exchange efficiency or performance.
As shown in fig. 6, a schematic diagram of an arrangement of the first flat tube group 300 and the second flat tube group 400 is shown, and in one possible design, the included angle between each first flat tube 310 and the horizontal plane is 13 ° to 20 °. In fig. 6, the dashed line represents a horizontal plane, and the included angle between the first flat tube 310 and the horizontal plane is measured by a neutral plane between the upper surface and the lower surface of the first flat tube 310 in each first flat tube 310, and the included angle range is within a range of 13 ° to 20 °. Thus, the standardized design, processing, etc. of the first flat tube 310 are facilitated.
Further, the included angle between each first flat tube 310 and the horizontal plane gradually increases from the second flat tube group 400 to the upper portion of the first collecting pipe 100. Exemplary, as shown in FIG. 6, the first flat tube 310 at the lowermost position in the first flat tube group 300 has an angle θ with the horizontal plane 11 =13°, upward θ 12 ＝13.1°，θ 13 =13.2°, … …, then the uppermost first flat tube 310 forms an angle θ with the horizontal plane 1n =20°. Thus, the first changeThe section of the hot air duct 320 from the inlet to the outlet gradually increases, which is more beneficial to the flow in the air flow in the first heat exchange air duct 320, and the heat exchange effect is better.
Alternatively, the inclination angle of each first flat tube 310 is the same. Continuing to refer to FIG. 6, the angle θ between each first flat tube 310 in the first flat tube group 300 and the horizontal plane 11 ＝θ 12 ＝θ 13 ＝θ 1n And falls within the range of 13 ° to 20 °, the specific angle may be set according to the actual position in actual installation, and this embodiment is not limited thereto.
As further shown in fig. 6, in one possible design, each second flat tube 410 is parallel to the horizontal plane. In this way, the air at the air inlet 30 may pass through each of the second heat exchange air ducts 420 and then blow backward in a direction parallel to the horizontal plane.
In another possible design, as shown in fig. 7, another arrangement of the first flat tube group 300 and the second flat tube group 400 is shown, where each of the second flat tubes 410 is disposed obliquely toward the lower portion of the first header 100. Each second flat tube 410 is disposed obliquely along the direction from the head to the tail and downward. Thus, the second flat tube 410, which is disposed obliquely, also increases the frontal area and the heat exchanging surface is larger than the flat tube disposed in parallel with the horizontal plane. Moreover, it will be appreciated that when the wind at the air inlet 30 passes through the second heat exchange duct 420, the wind is directed rearward and downward, i.e., the wind is directed and conveyed toward a rear larger mouth surface, further increasing the heat spreading range, thereby improving the overall heat exchange efficiency or performance of the heat exchanger 10.
Further, the included angle between each second flat tube 410 and the horizontal plane is 13 ° to 20 °. In fig. 7, the dashed line represents a horizontal plane, and the included angle between the second flat tube 410 and the horizontal plane is measured by the neutral plane between the upper surface and the lower surface of the second flat tube 410 in each second flat tube 410, and the included angle range is also within the range of 13 ° to 20 °. Thus, the standardized design, processing, etc. of the second flat tube 410 are also facilitated.
In addition, in one possible design, the included angle between each second flat tube 410 and the horizontal plane is from the first flat tube group 300 to the first collecting pipe 1The lower portion of 00 increases gradually in sequence. Exemplary, as shown in FIG. 7, the second flat tube 410 at the uppermost position in the second flat tube group 400 has an angle θ with the horizontal plane 21 =13°, downward θ 22 ＝13.1°，θ 23 =13.2°, … …, then the angle θ between the second flat tube 410 at the lowest position and the horizontal plane 2n =20°. In this way, the section of the second heat exchange air duct 420 from the inlet to the outlet is gradually increased, which is more beneficial to the flow in the second heat exchange air duct 420 in the air flow, and the heat exchange effect is better.
Alternatively, the inclination angle of each second flat tube 410 is the same. Continuing to refer to FIG. 7, the angle θ between each second flat tube 410 of the second flat tube group 400 and the horizontal plane 21 ＝θ 22 ＝θ 23 ＝θ 2n And falls within the range of 13 ° to 20 °, the specific angle may be set according to the actual position in actual installation, and this embodiment is not limited thereto.
In the heat exchanger 10 provided by the embodiment of the present utility model, in one possible design, fins are disposed between at least one of the two adjacent first flat tubes 310 and the two adjacent second flat tubes 410. For further increasing the heat exchanging area of the first heat exchanging channel 320 or the second heat exchanging channel 420, not shown in the drawing, corrugated fins made of aluminum or aluminum alloy material may be used as the fins. The thickness of the fin may be 0.06 to 0.12mm, and the wave height of the fin in the up-down direction may be 5 to 8mm. For example, the fins may be joined to the upper surface of one of the adjacent two first flat tubes 310 and the other lower surface thereof, for example, by brazing. The fins may also be joined to the upper surface of one of the adjacent two second flat tubes 410 and the other lower surface thereof, also by brazing.
