DETAILED DESCRIPTION

[0023] Typically, the heat exchange system of a power module (including but not limited to heat-generating components such as IGBT modules, battery cells, motors and chips) is mostly composed of a heat pipe heat exchanger, which consists of an evaporation section and a condensation section. The heating end of the power module is fixedly installed on the evaporation section of the heat pipe heat exchanger by contact or embedded means, and the condensation section dissipates heat into the atmosphere by air cooling.

[0024] The heat exchange system of the current power module is composed of a plurality of independently operated heat pipe heat exchangers. As a result, the plurality of heat pipe heat exchangers are arranged in a relatively dispersed manner, resulting in a large overall volume, which is not conducive to the miniaturization of the heat exchange system.

[0025] See also Figure 1-Figure 5 Therefore, in order to solve the problem of low integration of the heat exchange system of the existing power module 500, the present application provides an integrated heat exchange device, which includes a frame 100, a fan 300 and a heat pipe exchanger 400. The frame 100 is provided with a accommodating cavity 200 and a side opening 212 and a top opening 610 respectively connected to the accommodating cavity 200.

[0026] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, in one embodiment, the frame 100 includes a plurality of cross beams 110 and longitudinal beams 120 that are cross-arranged and welded.

[0027] Such an arrangement can significantly improve the structural strength of the frame 100 .

[0028] However, it is not limited thereto. In other embodiments, the frame 100 may be an integrally formed structure.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the fan 300 is blocked at the top opening 610 , a plurality of side openings 212 are distributed along the circumference of the frame 100 , and the heat pipe exchanger 400 is blocked at the side openings 212 .

[0030] Specifically, the fan 300 is horizontally or nearly horizontally arranged at the top opening 610, and the heat pipe exchanger 400 is vertically or nearly vertically arranged at the side opening 212. Such a layout is conducive to the uniform passage of airflow through the condensing section 420 of each heat pipe heat exchanger 400, and the vertical arrangement of the heat pipe heat exchanger 400 is conducive to the condensation and reflux of the gaseous working medium in the condensing section 420 under the action of gravity.

[0031] Furthermore, when the frame 100 is in a quadrangular prism shape, the frame 100 has four side openings 212, and each side opening 212 is provided with a corresponding heat pipe heat exchanger 400. When the frame 100 is in other shapes such as a triangular pyramid, a pentagonal prism or a hexagonal prism, the number of the heat pipe heat exchangers 400 will also change accordingly.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the power module 500 is disposed in the evaporation section 410 of the heat pipe heat exchanger 400 .

[0033] Specifically, one or more power modules 500 can be attached to the surface of the evaporation section 410, or partially immersed in the evaporation section 410 and sealed and welded to the shell of the evaporation section 410, or the power module 500 can be completely immersed in the liquid working medium of the evaporation section 410.

[0034] More specifically, in one embodiment, the power module 500 is bonded to the outer wall surface of the evaporation section 410 by thermally conductive silicone grease. In the working state, the top height of the power module 500 is lower than the liquid level of the liquid working medium in the evaporation section 410 .

[0035] When the fan 300 is running, the condensing section 420 of each heat pipe heat exchanger 400 can be connected to the fan 300 through the accommodating cavity 200 .

[0036] It should be noted that a motor (not shown) for driving the fan 300 to rotate may be disposed between the fan 300 and the frame 100 to further reduce the volume of the integrated heat exchange device.

[0037] It should be noted that "blocked" means that the heat pipe heat exchanger 400 completely covers the corresponding side opening 212, so that the airflow can only flow from the condensing section 420 of the heat pipe heat exchanger 400 through the side opening 212, and the fan 300 completely covers the corresponding top opening 610, so that the airflow can only flow from the fan 300 through the top opening 610. This arrangement can ensure that the airflow used to dissipate heat from the condensing section 420 can completely pass through the condensing section 420, so as to maximize the heat exchange efficiency of the integrated heat exchange device.

[0038] Further, it should be noted that the airflow passing through the condensing section 420 refers to the airflow passing through the part of the condensing section 420 provided with the external fins 422, rather than the airflow passing through the part of the condensing section 420 provided with the gaseous working fluid, that is, the airflow and the internal working fluid are not connected, and the airflow passes through the external fins 422 and the working fluid inside the condensing section 420 for heat exchange.

[0039] Specifically, Figure 3 As shown, the condensation section 420 includes a plurality of condensation channels 421 respectively connected to the evaporation section 410 , and adjacent condensation channels 421 are spaced apart and provided with external fins 422 . The gaseous working fluid in the condensation channel 421 can transfer heat to the external fins 422 through the side walls of the condensation channel 421 , and the airflow passes through the area between adjacent condensation channels 421 and takes away the heat of the external fins 422 .

[0040] In one embodiment, the airflow generated by the fan 300 flows in a direction away from the accommodating chamber 200 , that is, in this embodiment, the top opening 610 is the air outlet of the accommodating chamber 200 , and the side opening 212 is the air inlet of the accommodating chamber 200 .

[0041] With such arrangement, the fan 300 can draw gas from the accommodating chamber 200 to form a negative pressure environment, so that external air can enter the accommodating chamber 200 through the condensing sections 420 of each heat pipe heat exchanger 400, thereby forming an airflow.

[0042] But not limited to this, in another embodiment, the airflow generated by the fan 300 flows in the direction facing the accommodating cavity 200, that is, in this embodiment, the top opening 610 is the air inlet of the accommodating cavity 200, and the side opening 212 is the air outlet of the accommodating cavity 200.

[0043] With such arrangement, the fan 300 can fill the accommodating chamber 200 with gas to form a pressurized environment, so that the air in the accommodating chamber 200 is discharged outside the accommodating chamber 200 through the condensing sections 420 of each heat pipe exchanger 400, thereby forming an airflow.

[0044] From the above, it can be seen that the integrated heat exchange device provided by the present application, by setting up a frame 100, centrally arranges multiple heat pipe heat exchangers 400 and corresponding fans 300, which can not only effectively improve the layout integration of the heat pipe heat exchanger 400, and is conducive to the centralized maintenance of the heat pipe heat exchanger 400, but also avoids the hot air discharged from each heat pipe heat exchanger 400 interfering with each other, resulting in a decrease in the heat dissipation efficiency of the heat pipe heat exchanger 400, that is, it can significantly improve the heat dissipation efficiency of each heat pipe heat exchanger 400.

[0045] In one embodiment, if Figure 1 , Figure 2 and Figure 5As shown, the integrated heat exchange device further includes a top plate 600 , which is disposed at the top of the frame 100 , and a top opening 610 is disposed on the top plate 600 , and the top opening 610 is circular, and the diameter of the top opening 610 is slightly larger than the rotation diameter of the fan 300 .

[0046] Such a configuration is beneficial for the fan 300 to cover the top opening 610 .

[0047] Further, in one embodiment, if Figure 1 , Figure 2 and Figure 5 As shown, the integrated heat exchange device further includes an air shield 700 , which is sleeved on the outside of the fan 300 , and the air shield 700 and the top opening 610 are coaxially arranged.

[0048] With such arrangement, the wind shield 700 can guide the airflow generated by the fan 300 and prevent turbulence from being generated at the top opening 610 .

[0049] In one embodiment, if Figure 2 and Figure 5 As shown, the integrated heat exchange device also includes a main partition 800, which is located in the accommodating chamber 200 and is arranged at the connection between the evaporation section 410 and the condensation section 420, and the main partition 800 divides the accommodating chamber 200 into a first chamber 210 and a second chamber 220, wherein the first chamber 210 is arranged corresponding to the condensation section 420, and the fan 300 is connected to the condensation section 420 of each heat pipe exchanger 400 through the first chamber 210, and the second chamber 220 is arranged corresponding to the evaporation section 410.

[0050] Since the airflow only needs to cool the condensation section 420 , the main partition 800 is provided to separate the accommodating chamber 200 , thereby effectively improving the circulation efficiency of the airflow.

[0051] Specifically, the main partition plate 800 is welded or clamped between the evaporation section 410 and the condensation section 420 .

[0052] Furthermore, in other embodiments, the main partition 800 may also be disposed at the bottom of the accommodating cavity 200 .

[0053] In one embodiment, if Figure 5 As shown, the integrated heat exchange device also includes a plurality of inner partitions 900, which are arranged in the first cavity 210 and divide the first cavity 210 into a plurality of branch channels 211 arranged in parallel, the branch channels 211 and the heat pipe exchangers 400 are arranged in one-to-one correspondence, and the condensing section 420 of each heat pipe exchanger 400 is connected to the fan 300 through the corresponding branch channels 211.

[0054] Specifically, in one embodiment, if Figure 5 As shown, the inner partition 900 includes a first plate 910 and a second plate 920 both of which are vertically arranged. The first plate 910 and the second plate 920 are cross-arranged vertically and divide the first cavity 210 into four branch channels 211 arranged in parallel.

[0055] However, it is not limited thereto. In other embodiments, the inner partition 900 may also divide the first cavity 210 into two, three, five or more branch channels 211, which are not listed here one by one.

[0056] Such an arrangement can prevent the airflows passing through the heat pipe heat exchangers 400 from interfering with each other.

[0057] Further, in one embodiment, if Figure 5 As shown, there are multiple fans 300 , and the fans 300 and the branch channels 211 are arranged in a one-to-one correspondence.

[0058] Such an arrangement can avoid the failure of all the heat pipe heat exchangers 400 to exchange heat normally due to damage of one of the fans 300, thereby greatly improving the operating fault tolerance of the integrated heat exchange device.

[0059] Correspondingly, the number of top openings 610 disposed on the top plate 600 is also plural, and the top openings 610 and the fans 300 are disposed in one-to-one correspondence.

[0060] But not limited thereto, in other embodiments, the number of the fan 300 may be one, so as to reduce manufacturing costs and reduce the volume of the entire integrated heat exchange device.
