Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to an electronically controlled power module heat dissipation system, a vehicle thermal management integrated system, and a vehicle. Background Technology

[0002] In recent years, electronically controlled power modules have been widely used in new energy vehicles, switching power supplies, and autonomous driving. With the rapid development of electronic technology and high-power semiconductor manufacturing technology, the operating voltage, current, and output power of electronically controlled power modules are increasing, the output frequency is becoming larger, and the physical size is becoming smaller. This results in increasingly higher temperature rises during the operation of electronically controlled power modules. If the heat generated cannot be dissipated in time, it will directly affect the normal use of the electronically controlled power modules.

[0003] In the current electronic power module cooling system, the electronic power module mainly dissipates heat through the cooling medium. After heat exchange, the cooling medium returns to the water tank. During the circulation process, the temperature of the cooling medium gradually increases, resulting in a high temperature of the cooling medium flowing through the electronic power module. This leads to poor overall heat dissipation of the electronic power module cooling system, which in turn affects the working efficiency and reliability of the electronic power module.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0041] This application provides a heat dissipation system 1 for an electronically controlled power module. Please refer to [link / reference]. Figure 1 The heat dissipation system 1 for the power control module includes a power control module 11. The power control module 11 is a major control module in the fields of new energy vehicles, switching power supplies and autonomous driving. It includes power control devices and matching heat dissipation structures. During operation, the power control devices generate a lot of heat due to their large operating voltage, current and output power. The generated heat can be carried away by heat exchange through the corresponding heat dissipation structure to ensure the stable operation of the power control devices.

[0042] The power control module heat dissipation system 1 includes a cooling component 12, which is connected to the power control module 11. The cooling component 12 provides a cooling medium to the power control module 11, enabling heat exchange between the cooling medium and the power control module 11. Specifically, the cooling component 12 is connected to the heat dissipation structure in the power control module 11. The cooling medium can flow from the cooling component 12 to the heat dissipation structure in the power control module 11 and exchange heat with the power control devices in the power control module 11 to remove the heat generated by the power control devices and lower their temperature. After heat exchange, the cooling medium flows back to the cooling component 12 to achieve cyclic cooling, thereby maintaining the power control devices within a stable operating temperature range.

[0043] The heat dissipation system 1 for the electronically controlled power module includes a cooling component 13 connected to a cooling component 12. The cooling component 13 provides a cooling medium to the cooling component 12, allowing heat exchange between the cooling medium and the cooling medium to reduce the temperature of the cooling medium. During the circulating cooling of the electronically controlled power module 11, the temperature of the cooling medium may not decrease promptly after heat exchange with the electronically controlled power devices, causing the temperature of the cooling medium to gradually rise during the circulating cooling process, thus affecting the heat exchange efficiency between the cooling medium and the electronically controlled power devices.

[0044] By using the refrigeration component 13 to provide a cooling medium to the cooling component 12 and using the refrigeration medium to exchange heat with the cooling medium, the heat absorbed by the cooling medium during the circulation process can be removed in a timely manner, so as to ensure the heat exchange efficiency between the cooling medium and the electronic power device. At the same time, the refrigeration medium can also play a role in pre-cooling the cooling medium, so that the temperature of the cooling medium can be reduced to a lower level before exchanging heat with the electronic power device, thereby effectively improving the heat exchange efficiency between the cooling medium and the electronic power device, and thus improving the overall heat dissipation effect of the electronic power module heat dissipation system 1, ensuring the stable operation of the electronic power module 11.

[0045] Furthermore, by using the refrigerant to pre-cool the cooling medium, the heat dissipation capacity can be improved while ensuring the heat dissipation capacity of the cooling medium itself. In other words, even if the refrigerant circuit fails, the power module heat dissipation system 1 can still maintain basic heat dissipation capacity under the circulation of the cooling medium, thereby effectively improving the reliability of the thermal management of the power module heat dissipation system 1 and reducing the probability of thermal management failure of the power module heat dissipation system 1.

[0046] It should be noted that, for improving heat exchange efficiency by using a refrigerant to pre-cool the cooling medium, the principle of Newton's law of cooling, q = hA(T), can be applied. w -T f The following is a detailed explanation:

[0047] Where q is the heat transfer rate, h is the convective heat transfer coefficient, A is the heat transfer surface area, and T is the heat transfer coefficient. w T represents the surface temperature of the electronically controlled power device. f The temperature of the cooling medium is denoted as T. The cooling medium is rapidly cooled using a refrigerant to achieve pre-cooling, allowing it to enter the electronically controlled power module 11 at a temperature T. f Decrease, T f Reducing the heat transfer rate q can increase the heat transfer efficiency, thereby effectively improving the heat exchange efficiency of the entire electronic power module 11.

[0048] The power module heat dissipation system 1 in this embodiment includes a power module 11, a cooling component 12, and a refrigeration component 13. The cooling component 12 is connected to the power module 11 and provides a cooling medium to the power module 11. The refrigeration component 13 is connected to the cooling component 12 and provides a cooling medium to the cooling component 12. By using the refrigeration component 13 to provide a cooling medium to the cooling component 12, heat exchange occurs between the cooling medium and the refrigeration component, reducing the temperature of the cooling medium and achieving pre-cooling of the cooling medium. The cooled cooling medium is then used to exchange heat with the power module 11, effectively improving the heat exchange efficiency between the cooling medium and the power module 11, thereby improving the overall heat dissipation effect of the power module heat dissipation system 1.

[0049] In some embodiments, the refrigerant includes a refrigerant and the cooling medium includes a coolant (such as circulating water). Since the refrigerant has a strong instantaneous cooling capacity, by using the refrigerant as the refrigerant, the pre-cooling of the coolant can be completed in a short time, so that the temperature of the coolant can be reduced instantly, thereby ensuring the heat exchange capacity of the coolant during long-term circulation, and thus ensuring the long-term stable operation of the electronic power module 11.

[0050] In some embodiments, please refer to Figure 1 The cooling assembly 12 includes a heat exchange structure 121, which is connected to the electronic power module 11 and the refrigeration assembly 13. The heat exchange structure 121 has a first flow channel (not shown in the figure) and a second flow channel (not shown in the figure). The first flow channel is used for the flow of the refrigerant, and the second flow channel is used for the flow of the cooling medium, enabling heat exchange between the cooling medium and the refrigerant. That is, the heat exchange structure 121 serves as both a link in the cooling circuit of the electronic power module 11 and a link in the cooling circuit of the refrigeration assembly 13. Both the refrigerant and the cooling medium flow within the heat exchange structure 121 and exchange heat while passing through it simultaneously.

[0051] The first and second flow channels are independent of each other to avoid mixing and crosstalk between the refrigerant and cooling medium when they flow within the heat exchange structure 121, thus ensuring the circulation stability of each medium. Simultaneously, the first and second flow channels cooperate to allow heat exchange between the refrigerant and cooling medium within the heat exchange structure 121. This facilitates pre-cooling of the cooling medium by the refrigerant, lowering its temperature before heat exchange with the power control devices. This effectively improves the heat exchange efficiency between the cooling medium and the power control devices, thereby enhancing the overall heat dissipation effect of the power control module's cooling system 1 and ensuring the stable operation of the power control module 11.

[0052] In some embodiments, please refer to Figure 3 and Figure 4 The heat exchange structure 121 is provided with a first inlet 1211, a first outlet 1212, a second inlet 1213, and a second outlet 1214. The first inlet 1211 and the first outlet 1212 are respectively connected to a first flow channel, which is used for the inflow and outflow of the refrigerant. The second inlet 1213 and the second outlet 1214 are respectively connected to a second flow channel, which is used for the inflow and outflow of the cooling medium. That is, the connecting channel between the first inlet 1211 and the first outlet 1212 constitutes the first flow channel for the flow of the refrigerant, and the connecting channel between the second inlet 1213 and the second outlet 1214 constitutes the second flow channel for the flow of the cooling medium. By designing the distribution of the first inlet 1211, the first outlet 1212, the second inlet 1213, and the second outlet 1214, the distribution of the first and second flow channels within the heat exchange structure 121 can be adjusted to ensure the heat exchange efficiency between the refrigerant and the cooling medium within the heat exchange structure 121.

[0053] In some examples, please refer to Figure 3 The first inlet 1211 and the second inlet 1213 are located on the first side 1215 of the heat exchange structure 121, and the first outlet 1212 and the second outlet 1214 are located on the second side 1216 of the heat exchange structure 121. The first side 1215 and the second side 1216 are arranged opposite to each other. That is, the first inlet 1211 and the second inlet 1213 are located on the same side of the heat exchange structure 121, and the first outlet 1212 and the second outlet 1214 are located on the same side of the heat exchange structure 121, so as to simplify the structural design of the first flow channel and the second flow channel within the heat exchange structure 121.

[0054] The first inlet 1211 and the second inlet 1213 are distributed along the first direction X, and the first outlet 1212 and the second outlet 1214 are distributed in opposite directions along the first direction X. That is, the refrigerant and cooling media flow in the same forward direction, but in opposite directions perpendicular to the forward direction. For example, the refrigerant generally flows from the lower left to the upper right, while the cooling media generally flows from the upper left to the lower right. This ensures that although the refrigerant and cooling media flow in the same forward direction, there is still a certain degree of opposing flow, which helps to improve the heat exchange efficiency between the refrigerant and cooling media.

[0055] In some examples, please refer to Figure 4The first inlet 1211 and the second outlet 1214 are located on the first side 1215 of the heat exchange structure 121, and the second inlet 1213 and the first outlet 1212 are located on the second side 1216 of the heat exchange structure 121. The first side 1215 and the second side 1216 are arranged opposite to each other. That is, the first inlet 1211 and the second outlet 1214 are located on the same side of the heat exchange structure 121, and the second inlet 1213 and the first outlet 1212 are located on the same side of the heat exchange structure 121. In other words, the refrigerant and the cooling medium flow in opposite directions. For example, the refrigerant flows from left to right and the cooling medium flows from right to left, so that the refrigerant and the cooling medium can directly adopt a countercurrent flow mode to improve the heat exchange efficiency between the refrigerant and the cooling medium.

[0056] It should be noted that, in addition to the distribution method shown in the above embodiments, the inlet and outlet of the refrigerant and cooling medium can also be designed and adjusted according to the actual heat exchange requirements. As long as the heat exchange efficiency of the refrigerant and cooling medium when flowing in the heat exchange structure 121 is guaranteed, no special restrictions are imposed here.

[0057] In some embodiments, please refer to Figure 1 The cooling assembly 12 also includes a liquid storage device 122, which is connected between the electronic power module 11 and the heat exchange structure 121. The liquid storage device 122 is used to store and provide the cooling medium. That is, the liquid storage device 122 serves as the source of the cooling medium, both storing and participating in the circulation of the cooling medium. The output end of the liquid storage device 122 is connected to the second inlet 1213 on the heat exchange structure 121, and the input end of the liquid storage device 122 is connected to the output end of the heat dissipation structure in the electronic power module 11. The cooling medium flows from the liquid storage device 122 through the second inlet 1213 into the heat exchange structure 121, where it exchanges heat with the cooling medium. After the temperature decreases, the cooling medium flows through the second outlet 1214 into the heat dissipation structure of the electronic power module 11, where it exchanges heat with the electronic power devices of the electronic power module 11 to remove the heat generated by the electronic power devices. After the temperature rises, the cooling medium flows back into the liquid storage device 122, thereby realizing the cyclic cooling of the cooling medium.

[0058] In some embodiments, the cooling assembly 12 further includes a drive member 123, which is connected between the heat exchange structure 121 and the electronically controlled power module 11. The drive member 123 drives the cooling medium to flow within the heat exchange structure 121 and the electronically controlled power module 11, and exchanges heat with the cooling medium and the electronically controlled power module 11 respectively. The drive member 123 serves as the power source for the circulation of the cooling medium, driving the cooling medium to flow out of and into the liquid storage container 122, and to exchange heat with the cooling medium and the electronically controlled power module 11 during the flow process, thereby achieving cyclic cooling of the cooling medium.

[0059] In some embodiments, please refer to Figure 2 The power control module cooling system 1 also includes a motor module 14, which is connected to a cooling assembly 12. The cooling assembly 12 provides a cooling medium to the motor module 14, enabling heat exchange between the cooling medium and the motor module 14. In other words, the motor module 14 and the power control module 11 share the same cooling system. The cooling assembly 12 simultaneously provides cooling media to both the motor module 14 and the power control module 11 to cool and dissipate heat, ensuring their stable operation. By sharing the same cooling system, the integration of the power control module cooling system 1 is effectively improved, as is the utilization rate of the cooling medium.

[0060] In some examples, the motor module 14 is connected in series between the electronic power module 11 and the heat exchange structure 121, that is, the motor module 14 and the electronic power module 11 are connected in series in the same cooling circuit. On the one hand, this helps to simplify the cooling circuit design of the cooling component 12. On the other hand, under the drive of the same circulating power, both the motor module 14 and the electronic power module 11 can exchange heat with a sufficient amount of cooling medium to avoid uneven distribution of the cooling medium, which would result in insufficient heat exchange in one of them, thereby ensuring the heat exchange effect between the motor module 14 and the electronic power module 11 and the cooling medium.

[0061] In some examples, the cooling medium flows sequentially through the power control module 11 and the motor module 14, and exchanges heat with both modules in turn. Since the power control devices in the power control module 11 generate a significant amount of heat during operation, and these devices are more susceptible to temperature fluctuations than the motor, by sequentially flowing the cooling medium through both modules, the integration of the power control module's heat dissipation system 1 is improved. This allows the cooling medium to effectively remove the heat generated by the power control devices and also enables heat exchange with the motor, thus ensuring stable operation for both the power control devices and the motor.

[0062] In some examples, the motor module 14 and the electronic power module 11 can also be connected in parallel so that the cooling medium can exchange heat with the motor and the electronic power device independently, thereby ensuring the heat exchange effect between the cooling medium and the motor and the electronic power device.

[0063] It should be noted that the specific connection method between the motor module 14 and the power control module 11 can be selected and adjusted according to actual design requirements. As long as the heat exchange effect of the motor module 14 and the power control module 11 is guaranteed, no special restrictions are imposed here.

[0064] In some embodiments, the refrigeration assembly 13 includes a compressor 131 and a first heat exchanger 132 connected to each other. The compressor 131 provides a refrigerant, and the first heat exchanger 132 allows the refrigerant to flow and exchanges heat with it to lower its temperature. When the refrigerant is a coolant, the coolant output from the compressor 131 is in a high-temperature, high-pressure state. Before the coolant flows into the heat exchange structure 121 of the cooling assembly 12, it needs to be cooled. Therefore, the first heat exchanger 132 can be provided between the output end of the compressor 131 and the heat exchange structure 121 of the cooling assembly 12. The first heat exchanger 132 can be an in-vehicle condenser. After the coolant is output from the compressor 131, it is condensed by the first heat exchanger 132 to lower its temperature.

[0065] In some examples, to further cool the refrigerant, a fourth heat exchanger 133 can be added between the first heat exchanger 132 and the heat exchange structure 121 of the cooling assembly 12. The fourth heat exchanger 133 can be an external condenser. After the refrigerant is output from the compressor 131, it is condensed in sequence through the first heat exchanger 132 and the fourth heat exchanger 133 to reduce the temperature of the refrigerant.

[0066] In some examples, an expansion valve 15 may also be provided between the heat exchange structure 121 of the refrigeration component 13 and the cooling component 12. The expansion valve 15 is used to regulate the flow state of the refrigerant. After the refrigerant is output from the compressor 131, it passes through the first heat exchanger 132 and the fourth heat exchanger 133 in sequence to condense. After the flow state is regulated by the expansion valve 15, it enters the heat exchange structure 121 of the cooling component 12 and exchanges heat with the cooling medium flowing into the heat exchange structure 121 to reduce the temperature of the cooling medium and ensure the heat exchange effect between the cooling medium and the electronic power module 11.

[0067] In some examples, a gas-liquid separator 16 may be provided between the heat exchange structure 121 of the cooling assembly 12 and the suction port of the compressor 131. After the refrigerant completes heat exchange with the cooling medium, a small amount of liquid droplets may still remain due to droplet entrainment. By providing a gas-liquid separator 16 between the heat exchange structure 121 and the suction port of the compressor 131, the liquid refrigerant can be stored in the gas-liquid separator 16, thereby achieving the function of gas-liquid separation and improving the flow stability of the refrigerant.

[0068] This application also provides a vehicle thermal management integrated system, which includes an electronic control power module cooling system. The specific structure of the electronic control power module cooling system is as described in the above embodiments. Since the vehicle thermal management integrated system in this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0069] Please see Figure 5 The vehicle thermal management integrated system 2 includes an electronic power module cooling system 1, which comprises an electronic power module 11, a cooling component 12, and a refrigeration component 13. The cooling component 12 is connected to the electronic power module 11 and provides a cooling medium to it. The refrigeration component 13 is connected to the cooling component 12 and provides a cooling medium to it. By utilizing the refrigeration component 13 to provide a cooling medium to the cooling component 12, heat exchange occurs between the cooling medium and the cooling medium, reducing the temperature of the cooling medium and achieving pre-cooling. The cooled cooling medium is then used for heat exchange with the electronic power module 11, effectively improving the heat exchange efficiency between them and thus improving the overall heat dissipation effect of the vehicle thermal management integrated system 2.

[0070] In some embodiments, the vehicle thermal management integrated system 2 further includes a battery heat exchange module 21, which is connected in parallel with the cooling component 12 in the electronic control power module cooling system 1. The battery heat exchange module 21 is also connected to a refrigeration component 13 in the electronic control power module cooling system 1. The refrigeration component 13 provides a cooling medium to the battery heat exchange module 21, enabling heat exchange between the cooling medium and the battery heat exchange module 21. In other words, the pre-cooling of the cooling medium and the heat dissipation of the in-vehicle battery heat exchange module 21 can be integrated into the same cooling system to improve the integration level of the vehicle thermal management integrated system 2.

[0071] In some examples, the battery heat exchange module 21 includes a second heat exchanger 211, which is connected to the refrigeration assembly 13. The second heat exchanger 211 is used to supply the flow of the refrigerant so that the refrigerant can exchange heat with the battery. That is, the second heat exchanger 211 is connected in parallel with the heat exchange structure 121 in the cooling assembly 12. The refrigerant output from the compressor 131 is condensed by the first heat exchanger 132 and the fourth heat exchanger 133 and then enters the second heat exchanger 211 and the heat exchange structure 121 in the cooling assembly 12, respectively, to complete the heat exchange with the battery and the cooling medium. After that, it is separated into gas and liquid by the gas-liquid separator 16 and then drawn into the compressor 131, thereby realizing the circulation of the refrigerant in the vehicle thermal management integrated system 2.

[0072] It should be noted that an expansion valve 15 can also be installed between the refrigeration component 13 and the second heat exchanger 211, and between the second heat exchanger 211 and the compressor 131. The expansion valve 15 is used to regulate the flow state of the refrigerant. After the refrigerant is output from the compressor 131, it passes through the first heat exchanger 132 and the fourth heat exchanger 133 in sequence for condensation. After the flow state of the refrigerant is regulated by the expansion valve 15, it enters the second heat exchanger 211 and exchanges heat with the battery to reduce the battery temperature. After the heat exchange, the refrigerant passes through the expansion valve 15 again for flow state regulation and then passes through the gas-liquid separator 16 for gas-liquid separation. After that, it is drawn into the compressor 131, thereby realizing the circulation of the refrigerant in the battery heat exchange module 21.

[0073] In some embodiments, the vehicle thermal management integrated system 2 further includes an in-vehicle cooling module 22, which is connected in parallel with the cooling component 12 in the electronic control power module cooling system 1. The in-vehicle cooling module 22 is also connected to the cooling component 13 in the electronic control power module cooling system 1. The cooling component 13 provides a cooling medium to the in-vehicle cooling module 22, enabling heat exchange between the cooling medium and the in-vehicle cooling module 22. That is, the pre-cooling of the cooling medium and the heat dissipation of the in-vehicle cooling module 22 can be integrated into the same cooling system to improve the integration of the vehicle thermal management integrated system 2.

[0074] In some examples, the in-vehicle cooling module 22 includes a third heat exchanger 221, which is connected to the cooling assembly 13. The third heat exchanger 221 is used to supply the flow of the refrigerant so that the refrigerant can exchange heat with the cooling space inside the vehicle. That is, the third heat exchanger 221 is connected in parallel with the heat exchange structure 121 in the cooling assembly 12. The refrigerant output from the compressor 131 is condensed by the first heat exchanger 132 and the fourth heat exchanger 133 and then enters the third heat exchanger 221 and the heat exchange structure 121 in the cooling assembly 12, respectively, to complete the heat exchange with the cooling space inside the vehicle and the cooling medium. After that, it is separated into gas and liquid by the gas-liquid separator 16 and then drawn into the compressor 131, thereby realizing the circulation of the refrigerant in the vehicle thermal management integrated system 2.

[0075] It should be noted that an expansion valve 15 can also be installed between the refrigeration component 13 and the third heat exchanger 221. The expansion valve 15 is used to regulate the flow state of the refrigerant. After the refrigerant is output from the compressor 131, it passes through the first heat exchanger 132 and the fourth heat exchanger 133 in sequence to condense. After the flow state of the refrigerant is regulated by the expansion valve 15, it enters the third heat exchanger 221 and exchanges heat with the vehicle's refrigeration space to reduce the temperature of the vehicle's refrigeration space. After the heat exchange, the refrigerant passes through the gas-liquid separator 16 for gas-liquid separation and is then drawn into the compressor 131, thereby realizing the circulation of the refrigerant in the vehicle's refrigeration module 22.

[0076] In some embodiments, the third heat exchanger 221 in the vehicle cooling module 22, the second heat exchanger 211 in the battery heat exchange module 21, and the heat exchange structure 121 in the cooling assembly 12 are connected in parallel to each other, so that the vehicle cooling, the heat dissipation of the vehicle battery, and the pre-cooling of the cooling medium are all integrated in the same heat dissipation system, thereby further improving the integration of the vehicle thermal management integrated system 2, effectively reducing the space occupation of the vehicle thermal management integrated system 2, reducing manufacturing costs, and improving the safety and reliability of the vehicle thermal management integrated system 2.
