DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] In the description of the present application, it should be understood that the terms "first", "second" are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, at least one of which can be one, two or more, unless otherwise specifically limited.

[0041] As an introduction to the embodiments of the present application, a heat exchange device is introduced, which is used to cool some energy storage converters in a wind cooling manner. This design has a low cost, and the heat exchange between the hot air inside the energy storage converter and the ambient air is achieved by a fan. However, this heat dissipation method can only be applied to devices with low power density per unit volume and low IP protection level.

[0042] Some energy storage converters are cooled in a liquid cooling manner. However, only the high-heat power devices are cooled by liquid cooling plates. In addition, on the basis of using the liquid cooling plates, a fan is used to disturb the flow inside the energy storage converter to strengthen the heat exchange between the air and the electronic components. However, as the volume of the energy storage converter becomes smaller and smaller, the heat flux density of the electronic components inside the energy storage converter becomes larger and larger, and the air temperature inside the energy storage converter also becomes higher and higher. The heat dissipation structure arranged on the energy storage box cannot quickly dissipate the heat of the electronic components inside the energy storage converter, and only the fan cannot meet the heat dissipation requirement. If all the heat generating devices or temperature sensitive devices are cooled by the liquid cooling manner, the cost will increase a lot, and at the same time, the application reliability and maintenance complexity are also hidden dangers.

[0043] Therefore, the embodiments of the present application provide a heat exchange device to overcome at least one of the above technical problems.

[0044] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 12 In the embodiments of the present application, the heat exchange device comprises a shell 10, a liquid cooling assembly 20 and a fan 30.

[0045] The shell 10 has a first accommodating cavity 11. The shell 10 is the outer shell of the entire heat exchange device. It contains the first accommodating cavity 11, and other components of the heat exchange device can be accommodated in the first accommodating cavity 11. The shell 10 also has an air inlet 12 and an air outlet 13 which communicate with the first accommodating cavity 11. The air inlet 12 and the air outlet 13 are responsible for the exchange of gas with the external environment. The external gas can enter the inside of the first accommodating cavity 11 through the air inlet 12, and the gas in the first accommodating cavity 11 can be discharged through the air outlet 13.

[0046] The liquid cooling assembly 20 is located in the first accommodating cavity 11 and connected to the shell 10. The liquid cooling assembly 20 comprises a plurality of liquid cooling plates 21. One side of each liquid cooling plate 21 is provided with a heat exchange channel 22 formed between two adjacent liquid cooling plates 21 or between the liquid cooling plate 21 and the shell 10. The heat exchange channel 22 is in communication with the air inlet 12 and the first accommodating cavity 11 respectively. After passing through the air inlet 12, the external air first enters between the two adjacent liquid cooling plates 21 or between the liquid cooling plate 21 and the shell 10 through the heat exchange channel 22, and is cooled by the liquid cooling plate 21 (the cooling liquid in the liquid cooling plate 21 exchanges heat with the air), and the cooled air can enter the first accommodating cavity 11 through the heat exchange channel 22.

[0047] The fan 30 is located in the first accommodating cavity 11 and connected to the shell 10. The fan 30 and the liquid cooling assembly 20 divide the first accommodating cavity 11 into a first compartment 111 and a second compartment 112. The first compartment 111 and the second compartment 112 are arranged in the second direction Y. The first compartment 111 is in communication with the air inlet 12 through the heat exchange channel 22, and the second compartment 112 is in communication with the air outlet 13. The fan 30 is used to guide the air in the first compartment 111 into the second compartment 112. It can be understood that the fan 30 can disturb the air in the first compartment 111, so that the air in the first accommodating cavity 11 flows in a certain direction from the first compartment 111 to the second compartment 112, thereby facilitating the cooled air in the first compartment 111 and the second compartment 112 to be discharged through the air outlet 13. That is, during use of the heat exchange device, the air in the first accommodating cavity 11 is first discharged through the air outlet 13 by the fan 30 arranged, so that a negative pressure is formed in the first accommodating cavity 11, thereby causing the external hot air to enter the first compartment 111 of the first accommodating cavity 11 through the air inlet 12. During the process of entering the first compartment 111, the external hot air passes through the heat exchange channel 22 on at least one side of the liquid cooling plate 21. After heat exchange with the liquid cooling plate 21, the hot air is cooled. The cooled air enters the first compartment 111 and the second compartment 112 and is discharged by the disturbance of the fan 30, so that the cold and hot air forms a circulation. When the heat exchange device is used in cooperation with the energy storage converter, the hot air in the energy storage converter is cooled, and then the cooled air is input into the energy storage converter. Under the disturbance of the fan 30, the air in the heat exchange device and the energy storage converter can flow in a certain direction. The flowing cooled air can quickly cool the electronic components in the energy storage converter, which can effectively solve the heat dissipation of the high heat flux electronic components in the energy storage converter.

[0048] Meanwhile, the fan 30 and the liquid cooling assembly 20 are both arranged in the first accommodating cavity 11 of the shell 10, and the generated noise can be blocked by the shell 10, reducing the influence of the noise, and the cooled air can also take away the heat generated on the fan 30 after entering the inside of the first accommodating cavity 11, cooling the fan 30 and prolonging the service life of the fan 30. By integrating the fan 30 and the liquid cooling assembly 20 together, the heat dissipation effect is improved, and the cost is reduced, and the reliability is improved.

[0049] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the heat exchange device further comprises a fin assembly 40. The fin assembly 40 is arranged in the heat exchange channel 22 and can be used to increase the heat exchange surface area of the hot air and the liquid cooling plate 21, and improve the heat exchange efficiency. The fin assembly 40 comprises a plurality of fin bodies 41, which are arranged along the second direction Y and connected with the liquid cooling plate 21, so as to maximize the heat exchange area and effect with the air. By arranging the plurality of fin bodies 41 in the heat exchange channel 22 and connecting them with the liquid cooling plate 21, a small channel is formed between two adjacent fin bodies 41 in the second direction Y for the passage of air, which can increase the heat exchange surface area of the liquid cooling plate 21 and air, so that the heat exchange is more efficient. The first direction X and the second direction Y intersect, and preferably, the first direction X and the second direction Y are perpendicular.

[0050] Please refer to Figure 3 , Figure 5 and Figure 6 In some embodiments, the heat exchange device comprises a plurality of fin assemblies 40, which are all arranged in the heat exchange channel 22 and arranged along the third direction Z. By arranging a plurality of fin assemblies 40 along the third direction Z, the contact area with the air in the direction of air flow can be further increased. Meanwhile, the fin bodies 41 of the adjacent two fin assemblies 40 are arranged in a staggered manner. By arranging a plurality of fin assemblies 40 in this staggered manner, the air in the heat exchange channel 22 can pass between the fin bodies 41 of the plurality of fin assemblies 40. This flow path uniformly distributes heat to different fin bodies 41 in order to more effectively dissipate heat and cool. Such staggered arrangement can also avoid blockage between the fin bodies 41, and the flow paths are interconnected, so that the air can pass through from a plurality of different paths, thereby ensuring that the air can freely pass through the heat exchange channel 22. The staggered arrangement means that the normal projection of the adjacent two fin bodies 41 on a plane perpendicular to the third direction Z has no overlapping part or only a part overlapping.

[0051] Please refer to Figure 7 andFigure 13 In some embodiments, the shell 10 comprises a plurality of plates 14 connected and surrounding the first accommodating cavity 11, the air inlet 12 and the air outlet 13 are arranged on the same plate 14; that is, the air inlet 12 and the air outlet 13 are arranged on the same side of the shell 10. The plurality of plates 14 surround to form the first accommodating cavity 11, and other structures such as the fan 30 are also installed inside the first accommodating cavity 11. In the process of cooperating with the energy storage converter, the heat exchange device can be installed outside the energy storage converter, and one plate 14 with the air inlet 12 and the air outlet 13 is fixedly connected with the energy storage converter, so that the air inlet 12 and the air outlet 13 are in communication with the space inside the energy storage converter. After communication, the fan 30 can disturb the air in the first accommodating cavity 11 and the space inside the energy storage converter, so that the air in the two spaces can circulate and flow, which is beneficial to cooling the electronic components inside the energy storage converter.

[0052] Since the plate 14 with the air inlet 12 and the air outlet 13 is closely connected with the energy storage converter, dust and water stains outside are not easy to enter the first accommodating cavity 11 through the air inlet 12 and the air outlet 13, which improves the protection level of the heat exchange device and can play a dustproof and waterproof role, reducing the probability of failure.

[0053] Please refer to Figure 8 and Figure 14 In some embodiments, the shell 10 comprises a plurality of plates 14 connected and surrounding the first accommodating cavity 11, the air inlet 12 is arranged on one plate 14, and the air outlet 13 is arranged on another plate 14; that is, the air inlet 12 and the air outlet 13 are arranged on different sides of the shell 10. At this time, the heat exchange device can be arranged inside the energy storage converter. Since the air inlet 12 and the air outlet 13 are located on different plates 14, that is, the air inlet 12 and the air outlet 13 are arranged on different sides, this arrangement and the connection mode of the heat exchanger and the energy storage converter can make the air inside the energy storage converter be disturbed more greatly, and the circulation range of the air is wider, which increases the cooling range inside the energy storage converter and improves the cooling effect.

[0054] Please refer to Figure 7 and Figure 8In some embodiments, the shell 10 is provided with a plurality of air outlets 13, which are arranged at intervals. Since the volume and surface area of the upper plate 14 of the shell 10 are subject to various constraints, the volume and surface area of the plate 14 change little during the design process. By providing a plurality of air outlets 13 on the plate 14, while keeping the air flow rate unchanged, the more the number of air outlets 13 and the smaller the area, the flow rate of air through each air outlet 13 will also increase to some extent, which will be faster than when only one large hole is provided on the plate 14. The flow rate of the air discharged by the heat exchange device increases, which can disturb the air inside the energy storage inverter to a greater extent. Increasing the flow rate of the air can speed up the air circulation and improve the heat dissipation efficiency of the electronic components inside the energy storage inverter.

[0055] Referring to Figure 9 In some embodiments, the fan 30 is configured to be arranged towards the air outlet 13. The fan 30 directly blows towards the air outlet 13 to discharge the cooled air in the first containing cavity 11 through the air outlet 13, without the need for the air after the disturbance to change the direction of movement, thereby reducing the energy loss of the air after the disturbance, so that the air can enter the interior of the energy storage inverter through the air outlet 13 at a larger flow rate. The air with a larger flow rate can speed up the circulation of the air in the heat exchange device and the energy storage inverter, thereby improving the heat dissipation efficiency of the electronic components inside the energy storage inverter.

[0056] Referring to Figure 1 , Figure 10 and Figure 11 In some embodiments, the liquid cooling plate 21 has a liquid cooling channel 211. The liquid cooling plate 21 can be a harmonica tube with a liquid cooling channel 211 inside for transferring cooling liquid. The heat on the air passing through the heat exchange channel 22 can be carried away by the flowing cooling liquid, and the air passing through the heat exchange channel 22 can be cooled by heat exchange. The liquid cooling assembly 20 includes a first flow collector 23, a second flow collector 24, and a third flow collector 25, which are located in the first containing cavity 11 and connected to a plurality of liquid cooling plates 21. The first flow collector 23, the second flow collector 24, and the third flow collector 25 facilitate the flow of cooling liquid to enter or exit the interior of the liquid cooling plate 21.

[0057] The first flow collector 23 has a first flow cavity 231 communicating with at least part of the liquid cooling channels 211, i.e. the cooling liquid can flow in the first flow cavity 231 and the liquid cooling channels 211 on part of the liquid cooling plates 21, the cooling liquid in the first flow cavity 231 can enter the liquid cooling channels 211, and the cooling liquid in the liquid cooling channels 211 can also enter the first flow cavity 231. The second flow collector 24 has a second flow cavity 241 communicating with the liquid cooling channels 211, i.e. the cooling liquid can flow in the second flow cavity 241 and the liquid cooling channels 211 on all the liquid cooling plates 21. The third flow collector 25 has a third flow cavity 251 communicating with at least part of the liquid cooling channels 211, i.e. the cooling liquid can flow in the third flow cavity 251 and the liquid cooling channels 211 on another part of the liquid cooling plates 21.

[0058] The first flow collector 23 and the third flow collector 25 are arranged on the same side of the liquid cooling plates 21 and communicate with different liquid cooling channels 211 respectively, and the second flow collector 24 is arranged on the other side of the liquid cooling plates 21 and communicates with all the liquid cooling channels 211. When the cooling liquid flows, the cooling liquid in the first flow cavity 231 can enter the second flow cavity 241 through part of the liquid cooling channels 211, and the cooling liquid in the second flow cavity 241 can enter the third flow cavity 251 through another part of the liquid cooling channels 211. Alternatively, the cooling liquid in the third flow cavity 251 can enter the second flow cavity 241 through part of the liquid cooling channels 211, and the cooling liquid in the second flow cavity 241 can enter the first flow cavity 231 through another part of the liquid cooling channels 211. Both of the two ways can take away the heat in the air passing through the heat exchange channels 22 by the flowing cooling liquid, so that the air is cooled, and the heat exchange effect is achieved.

[0059] Please refer to Figure 10 and Figure 11 In some embodiments, the first flow collector 23 has an inlet 232 communicating with the first flow cavity 231. The third flow collector 25 has an outlet 252 communicating with the third flow cavity 251. The corresponding pipeline outside the device is connected to the first flow cavity 231 through the inlet 232, the cooling liquid is input to the inside of the first flow cavity 231 through the corresponding pipeline and the inlet 232, the cooling liquid enters the second flow cavity 241 through part of the liquid cooling channels 211, the cooling liquid in the second flow cavity 241 enters the third flow cavity 251 through another part of the liquid cooling channels 211, and the third flow cavity 251 is connected to the corresponding pipeline through the outlet 252, so as to facilitate the output of the cooling liquid after heat exchange with the air through the corresponding pipeline.

[0060] Please refer to Figure 13 and Figure 14The energy storage box comprises a box body 50 and the heat exchange device as described above. The box body 50 has a second accommodating cavity 51 which can be used to accommodate other electronic structures which generate more heat during operation so that the temperature in the second accommodating cavity 51 is increased. The heat exchange device is connected to the box body 50, and the air inlet 12 of the heat exchange device and the air outlet 13 of the heat exchange device are both communicated with the second accommodating cavity 51. The heat exchange device can be arranged outside the box body 50 and connected to the box body 50, at this time, the air inlet 12 and the air outlet 13 of the heat exchange device are located on the same side and are both communicated with the second accommodating cavity 51, so that the air in the second accommodating cavity 51 is circulated and cooled, and the circulating air can cool the electronic structures with high temperature. By arranging the heat exchange device outside the box body 50, the heat exchange device can be conveniently maintained.

[0061] The heat exchange device can be arranged inside the box body 50 and connected to the box body 50, at this time, the air inlet 12 and the air outlet 13 of the heat exchange device can be located on different sides. When the air inlet 12 and the air outlet 13 are located on different sides, the air in the second accommodating cavity 51 can be disturbed and cooled to a greater extent, so that the circulating range of the air is larger and more electronic structures can be cooled.

[0062] Alternatively, the air inlet 12 is communicated with the external environment of the box body 50, and the air outlet 13 is communicated with the second accommodating cavity 51. The air inlet 12 is communicated with the external environment, and the air outlet 13 is communicated with the second accommodating cavity 51, so that the external air is cooled by the liquid cooling assembly 20 and then blown into the inside of the box body through the air outlet 13 to cool the inside of the box body, realizing external circulation.
