Description
Technical Field
[0001] This application relates to the field of automotive temperature control technology, and in particular to a heater core, an air conditioning system, and a vehicle. Background Technology
[0002] The heating source for automotive air conditioning systems typically comes from hot water from the engine or hot water heated by a high-pressure electric water heater. Modern air conditioning systems usually deliver heat directly to the heater core within the HVAC system to transfer heat into the vehicle interior. However, current heater cores generally consist of a heat exchanger, an inlet, and an outlet. This means that when the air conditioning requires less heat (i.e., low-temperature heating), the engine waste heat is high. Directly introducing hot water from the engine into the heater core would significantly impact the air conditioning temperature, failing to meet low-temperature heating demands. To meet these demands, in such situations, only hot water slightly warmer than ambient temperature can be provided by a high-pressure electric water heater, reducing overall vehicle fuel economy.

[0039] The following reference Figures 1 to 4 This application describes a warm air core 1 and an air conditioning system according to some embodiments.
[0040] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application provides a heater core 1, which includes a first liquid inlet 21, a second liquid inlet 22, a liquid outlet 31, a plurality of first flat tubes 11, and a plurality of second flat tubes 12. The first flat tubes 11 and the second flat tubes 12 are alternately arranged along a first direction F1 to form a heat dissipation core. The first flat tubes 11 are respectively connected to the first liquid inlet 21 and the liquid outlet 31, and the second flat tubes 12 are respectively connected to the second liquid inlet 22 and the liquid outlet 31. In this way, by setting the first flat tubes 11 connected to the first liquid inlet 21 and the liquid outlet 31 and the second flat tubes 12 connected to the second liquid inlet 22 and the liquid outlet 31, the heater core 1 is partitioned. The heater core valve body can be adjusted in three ways by controlling the connection to only the first flat tube 11, only the second flat tube 12, and both the first flat tube 11 and the second flat tube 12. This allows the heater core 1 to adapt to different temperature supply needs, thereby increasing the applicable range of engine waste heat heating and improving the energy economy of the vehicle.
[0041] like Figures 1 to 3 As shown in the figure, F1 can be an example of the first direction F1 described above, F2 can be an example of the second direction F2 described below, and F3 can be an example of the third direction F3 described below. The second direction F2 and the third direction F3 can intersect, and the first direction F1 can intersect the plane defined by the second direction F2 and the third direction F3. Preferably, the second direction F2 is perpendicular to the third direction F3, and the first direction F1 can be perpendicular to the plane defined by the second direction F2 and the third direction F3, to accommodate most cuboid warm air cores 1.
[0042] Preferably, such as Figure 1 As shown, the number of the first flat tubes 11 is greater than the number of the second flat tubes 12, so as to further increase the difference between the two settings of only connecting the first flat tubes 11 and only connecting the second flat tubes 12, and further improve the temperature adaptability range of the heater core 1.
[0043] Preferably, such as Figure 1 As shown, at least one first flat tube 11 is provided between each two adjacent second flat tubes 12 to improve the uniformity of the distribution of the first flat tubes 11 and the second flat tubes 12 in the first direction F1.
[0044] Furthermore, such as Figure 1 As shown, the number of first flat tubes 11 between each two adjacent second flat tubes 12 is equal, so as to further improve the uniformity of the distribution of the first flat tubes 11 and the second flat tubes 12 in the first direction F1.
[0045] like Figure 1 As shown in the figure, an example of two first flat tubes 11 arranged between each two adjacent second flat tubes 12 is shown. However, it is not limited to this. Three, four, or more first flat tubes 11 can also be arranged between each two adjacent second flat tubes 12.
[0046] Preferably, such as Figure 1 As shown, the aforementioned heater core 1 may further include a liquid inlet manifold 20, which extends along the first direction F1 and is disposed at one end of the heat dissipation core in the second direction F2. Figure 2 and Figure 3 As shown, the liquid inlet collection section 20 may be provided with a first liquid inlet chamber 201 and a second liquid inlet chamber 202 that are separated from each other. The first flat tube 11 is connected to the first liquid inlet section 21 via the first liquid inlet chamber 201, and the second flat tube 12 is connected to the second liquid inlet section 22 via the second liquid inlet chamber 202.
[0047] Preferably, such as Figure 2 and Figure 3 As shown, the ratio of the volume V1 of the first liquid inlet chamber 201 to the volume V2 of the second liquid inlet chamber 202 can be equal to the ratio of the number n1 of the first flat tubes 11 to the number n2 of the second flat tubes 12, that is, This effectively ensures the consistency of fluid flow velocity inside the first flat tube 11 and the second flat tube 12, thereby avoiding the occurrence of eddies in the liquid collection section 30 due to the inconsistent fluid flow velocity inside the first flat tube 11 and the second flat tube 12.
[0048] Preferably, such as Figure 2 and Figure 3 As shown, the above-mentioned heating core 1 may also include a liquid outlet collection section 30. The liquid outlet collection section 30 is disposed at the other end of the heat dissipation core in the second direction F2. The liquid outlet collection section 30 is provided with a liquid outlet collection cavity 301. The first flat tube 11 and the second flat tube 12 are both connected to the liquid outlet section 31 through the liquid outlet collection cavity 301 to realize the liquid return in the first flat tube 11 and the second flat tube 12.
[0049] Preferably, such as Figure 3As shown, the first flat tube 11 extends along the second direction F2 to guide fluid from the inlet collection section 20 to the outlet collection section 30. The first flat tube 11 may have a predetermined width in the third direction F3 to facilitate heat dissipation.
[0050] Preferably, such as Figure 3 As shown, the first flat tube 11 includes a plurality of first spacers 111 extending along the second direction F2. The plurality of first spacers 111 are spaced apart along the third direction F3 to form a plurality of first diversion channels arranged side by side along the third direction F3 within the first flat tube 11, so as to improve the uniformity of fluid distribution on the first flat tube 11.
[0051] Preferably, such as Figure 3 As shown, the first partition bar 111 can extend from one end of the first flat tube 11 near the liquid outlet collection section 30 along the second direction F2 to the end where the liquid inlet collection section 20 is located. The first partition bar 111 and the liquid inlet collection section 20 are spaced apart in the second direction F2 so that each first branch channel on the same first flat tube 11 is interconnected, thereby ensuring that the fluid flowing into the first flat tube 11 from the first liquid inlet chamber 201 can enter each first branch channel evenly.
[0052] Similarly, such as Figure 2 As shown, the second flat tube 12 may also extend along the second direction F2, so that the second flat tube 12 can guide the fluid from the inlet liquid collection section 20 to the outlet liquid collection section 30. The second flat tube 12 may also have a predetermined width in the third direction F3, so as to facilitate the heat dissipation of the second flat tube 12.
[0053] Similarly, such as Figure 2 As shown, the second flat tube 12 may include a plurality of second spacers 121 extending along the second direction F2. The plurality of second spacers 121 are spaced apart along the third direction F3 to form a plurality of second flow channels arranged side by side along the third direction F3 in the second flat tube 12, so as to improve the uniformity of fluid distribution on the second flat tube 12.
[0054] Similarly, such as Figure 2 As shown, the second partition bar 121 can extend from one end of the second flat tube 12 near the liquid outlet collection section 30 along the second direction F2 to the end where the liquid inlet collection section 20 is located, and the second partition bar 121 and the liquid inlet collection section 20 are spaced apart in the second direction F2, so that each second branch channel on the same second flat tube 12 is interconnected, thereby ensuring that the fluid flowing into the second flat tube 12 from the second liquid inlet chamber 202 can enter each second branch channel evenly.
[0055] See Figure 4The second aspect of this application also provides an air conditioning system including the heating core 1 described in any of the above embodiments, and thus has all the beneficial technical effects of the heating core 1, which will not be repeated here.
[0056] Preferably, such as Figure 4 As shown, the aforementioned air conditioning system may include a three-way valve, an engine assembly 5, an electric heating unit 6, a first circuit 41, a second circuit 42, and a third circuit 43. The first circuit 41, second circuit 42, and third circuit 43 are respectively connected to three ports of the three-way valve. For ease of description, the three ports of the three-way valve can be defined as the first port, the second port, and the third port, where the first port can be used to connect to the first circuit 41, the second port can be used to connect to the second circuit 42, and the third port can be used to connect to the third circuit 43.
[0057] The first liquid inlet 21 and the second liquid inlet 22 of the aforementioned heater core 1 can be connected to the first circuit 41, the liquid outlet 31 of the aforementioned heater core 1 can be connected to the second circuit 42, the aforementioned electric heating unit 6 can be installed in the first circuit 41, and the engine assembly 5 can be connected to the third circuit 43. Thus, the heat source switching of the heater core 1 can be achieved by controlling the connection relationship of the three-way valve. Specifically, when the first interface is connected to the second interface, the water path of the heater core 1 does not flow through the engine assembly 5, but only through the electric heating unit 6. At this time, the heat source of the heater core 1 is entirely provided by the electric heating unit 6. When the third interface is connected to the second interface, the water path of the heater core 1 flows through both the engine assembly 5 and the electric heating unit 6. At this time, the electric heating unit 6 can be inactive, and the hot water is entirely provided by the engine's waste heat water; alternatively, the electric heating unit 6 can also be active, and the hot water is jointly provided by the electric heating unit 6 and the engine's waste heat water.
[0058] Preferably, such as Figure 4 As shown, the first circuit 41 can also be equipped with a warm air water pump 9 to provide power for the circulation of the warm air heat source fluid.
[0059] Optionally, the aforementioned electric heating unit 6 may be an electric water heater.
[0060] Preferably, such as Figure 4 As shown, the first circuit 41 may also include a first branch 411 and a second branch 412. The first liquid inlet 21 is connected to the first circuit 41 via the first branch 411, and the second liquid inlet 22 is connected to the first circuit 41 via the second branch 412, so that the gear switching of the heater core 1 can be realized by controlling the on / off state of the first branch 411 and the second branch 412.
[0061] Optionally, such as Figure 4 As shown, the second circuit 42 can also be equipped with a water tank 8 to replenish the fluid in the air conditioning system.
[0062] Optionally, such as Figure 4 As shown, the engine assembly 5 may also be equipped with a thermostat 51 and an engine water pump 52. The air conditioning system may further include a fourth circuit 44, which connects the thermostat 51 and the engine water pump 52. This fourth circuit 44 also includes an engine radiator 71 to achieve rapid engine cooling. Further, as... Figure 4 As shown, the fourth circuit 44 may also include a fan 72, which may be located on one side of the engine radiator 71 to further improve the heat dissipation efficiency of the engine radiator 71.
[0063] According to a third aspect of this application, a vehicle is provided that includes a heating core as described in any of the above technical solutions, or includes an air conditioning system as described in any of the above technical solutions, and thus has all the beneficial technical effects of the heating core and the air conditioning system, which will not be repeated here.
[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
