[0025] The water-cooled power module has a water cooling system, and the water cooling system has multiple branches, each branch is used to dissipate heat for each functional module, and each branch has a water flow regulating component, so that the water cooling system can perform corresponding water flow regulation according to the specific working conditions of the functional module, thereby making the working temperature of each functional unit in the water-cooled power module basically consistent, thereby ensuring the overall performance of the water-cooled power module. By setting a branch of the water cooling system on each functional unit, each branch can independently control the water flow through the water flow regulating component. When the temperatures of multiple functional units differ, heat dissipation can be regulated through water flow control, thereby achieving normal operation of high-temperature components. The problem that the water-cooled power module in the related art cannot balance the heat dissipation of multiple components therein is solved.

[0026] In the above embodiment, Figure 1 As shown, the functional unit 22 is Figure 1 In the top view, it will be covered by the water cooling system located thereon. The temperature of the functional units 22 during operation is different, and the occupied area of ​​each functional unit 22 is also different. Therefore, it is necessary to design the water cooling system 21 located thereon for the functional units 22 in a targeted manner to avoid waste of resources.

[0027] In one alternative, Figure 1 and Figure 2As shown, the branch circuit also includes a heat dissipation component 30, and the heat dissipation component 30 includes a main heat dissipation part 31, a water inlet part 32, a water outlet part 33 and a plurality of temperature sensors 34, wherein: the water inlet part 32 is located at one side of the main heat dissipation part 31; the water outlet part 33 is located at the side of the main heat dissipation part 31 away from the water inlet part 32; the temperature sensor 34 is electrically connected to the main board 10, and the temperature sensors 34 are respectively located at the water inlet part 32 and the water outlet part 33; the main heat dissipation part 31 includes a water flow passage 40, and the water flow passage 40 is connected to the water outlet part 33 and the water inlet part 32, and the structure of the water flow passage 40 is a single channel, and the single channel includes a plurality of first parts 41 and a plurality of second parts 42, and the first parts 41 extend along the water inlet direction of the water inlet part 32, and the adjacent first parts 41 are connected to the second parts 42 to be arranged at intervals, so that the above The water flow passage 40 is through, or the structure of the water flow passage 40 is multi-channel, and the multi-channel includes a first part 41, a second part 42 and a plurality of third parts 43, the first part 41 connects the water inlet 32 ​​and the water outlet 33, the extension direction of the first part 41 near the water inlet 32 ​​is consistent with the water inlet direction of the water inlet 32, the extension direction of the first part 41 near the water outlet 33 is perpendicular to the water outlet direction of the water outlet 33, the second part 42 connects the water inlet 32 ​​and the water outlet 33, the extension direction of the second part 42 near the water inlet 32 ​​is perpendicular to the water inlet direction of the water inlet 32, the extension direction of the second part 42 near the water outlet 33 is consistent with the water outlet direction of the water outlet 33, and the third parts 43 are distributed at intervals by connecting to the first part 41 and the second part 42 respectively.

[0028] In the above embodiment, Figure 1 and Figure 2 As shown, the heat dissipation assembly 30 also includes a quick connector 35 and a fixing nut 36, which is quickly connected to the water inlet and outlet pipes of the water-cooled power module through the quick connector 35, while ensuring good sealing of the interface. The temperature sensor 34 is connected to the mainboard 10 through a cable, draws power from the mainboard 10, and transmits data with the mainboard 10. A hose can be used as a quick connector female at the water inlet 32 ​​and the water outlet 33 to facilitate fine-tuning the relative position of the main heat dissipation part 31 when fixing the main heat dissipation part 31. The fixing nut 36 is used to fix the main heat dissipation part 31 to the functional unit 22 to ensure good contact between the main heat dissipation part 31 and the functional unit 22. Thermal conductive silicone grease is applied to the contact surface between the main heat dissipation part 31 and the functional unit 22 to make the heat transfer from the functional unit 22 to the main heat dissipation part 31 faster; the main heat dissipation part 31 contains a tortuous water flow path 40 inside, which is used to increase the contact area between the cooling water and the main heat dissipation part 31 and improve the heat dissipation efficiency.

[0029] The outer dimensions of the main heat dissipation part 31 are determined by the size of the corresponding functional unit 22, and the water flow path 40 can be designed and optimized according to the heat generation of the functional unit 22. The water flow path 40 can include a single-channel type and a multi-channel type (Z-shaped pipeline). For example, for two functional units 22 with the same heat dissipation contact area, the functional unit 22 with a large heat generation should adopt a multi-channel design on the right side. The multi-channel type has a short water flow path, a small pipeline flow resistance, a faster cooling water flow speed, and a larger contact area with the main heat dissipation part 31, which can take away more heat.

[0030] The single-channel type includes a first portion 41 and a second portion 42, and the first portion 41 and the second portion 42 are interconnected to form a Figure 2 The multi-channel type includes a first portion 41, a second portion 42 and a third portion 43, and the first portion 41, the second portion 42 and the third portion 43 are interconnected to form a Figure 2 The figure on the right shows the morphology.

[0031] In one alternative, Figure 1 As shown, the branch line further includes a one-way valve 50 , and the one-way valve 50 is connected to the water outlet 33 .

[0032] In the above embodiment, Figure 1 As shown, the one-way valve 50 can prevent the water from flowing back, thereby preventing the cooling system of the branch from cooling normally, thereby damaging the overall cooling of the water-cooled power module.

[0033] In one alternative, Figure 1 As shown, the water-cooled power module further includes a main water inlet channel 60, a main water outlet channel 70 and a plurality of interfaces 80, wherein the main water inlet channel 60 is respectively connected to the water inlet portion 32 and the interface 80, and the main water outlet channel 70 is respectively connected to the water outlet portion 33 and the interface 80.

[0034] In the above embodiment, Figure 1As shown, the water-cooled power module can be conveniently maintained from the front and supports hot plugging of the power connector 120 and the heat dissipation component. The main water inlet channel 60 and the main water outlet channel 70 are both connected with an interface 80, which can be a quick connector male head, which is used in conjunction with the female head on the power supply frame to achieve quick disassembly and connection with the external pipeline. The main water outlet channel 70 has multiple openings, which are connected to the water flow regulating component 23. The water flow regulating component 23 can be an electronic ball valve, which is connected to the water inlet part 32 through a thread, and a sealing gasket is added to prevent leakage. The water flow regulating component 23 is connected to the mainboard 10 through a cable, draws power from the mainboard 10, and transmits data with the mainboard 10. The water flow regulating component 23 is controlled by the mainboard 10 (MCU); the water flow regulating component 23 can use the angle of the valve opening to control the cross-sectional area and the flow rate. The other end of the water flow regulating component 23 is a quick connector male head, which is matched with the quick connector female head of the water inlet part 32 of the main heat dissipation part 31 to achieve quick disassembly and connection, and the packaging has good sealing performance. The main water outlet channel 70 has multiple openings, which are connected to the one-way valve 50 through threads, and a sealing gasket is added to prevent leakage. The other end of the one-way valve 50 is a quick connector male head, which is matched with the quick connector female head of the water outlet part 33 of the main heat dissipation part 31 to achieve quick disassembly and assembly, and the packaging has good sealing performance.

[0035] When the water-cooled power module is working in the liquid cooling system, it is necessary to ensure that there is no gas in the loop, so the liquid cooling pipeline of the water-cooled power module should be filled with coolant first, and then connected to the system before it can be used directly to achieve blind insertion. When the water-cooled power module is stored separately, there is coolant in the main water inlet channel 60, the main water outlet channel 70 and the heat dissipation component, and the interface 80 remains closed to ensure that the internal coolant is isolated from the outside.

[0036] In one alternative, Figure 3 As shown, the water-cooled power module further includes a shell 90, a clip 100, a handle 110 and a connector 120, wherein: the clip 100 and the handle 110 are located on one side of the shell 90, the connector 120 is located on the side of the shell 90 away from the clip 100, and the main board is located inside the shell 90.

[0037] In the above embodiment, Figure 3As shown, the interface 80 of the water-cooled power module can be matched with the female quick connector fixed on the power frame, and the connector 120 of the power supply can be matched with the power connector in the power frame. When the power supply is inserted into the power frame, the protrusion of the buckle 100 protruding from the shell 90 of the power supply cooperates with the groove on the power frame to prevent the power supply from falling out; when the power supply needs to be unplugged, it is only necessary to toggle the buckle 100 to retract the protrusion protruding from the shell 90 into the shell 90, and pull the handle 110 to unplug the power supply. The power supply adopts a back-in-back-out power supply mode, that is, the water-cooled power module power supply, the water-cooled power module output power, and the water-cooled power module logic or control signal are all in the connector 120 of the power supply at the rear of the power supply, and are connected to the power frame through the connector 120 of the power supply.

[0038] In one alternative, Figure 1 As shown, the water-cooled power module further includes an air cooling component 130, which is located inside the housing and on the side of the mainboard 10 close to the handle. The air supply direction of the air cooling component 130 is the side where the handle points to the connector.

[0039] In the above embodiment, Figure 1 As shown, on the basis of the water cooling system in the water-cooled power module, an air cooling component 130 is also provided. The air outlet direction of the air cooling component 130 is from the power handle end to the power connector end (for Figure 1 ), the air cooling assembly 130 dissipates part of the heat diffused into the air from the water-cooled power module.

[0040] According to another embodiment of the present application, a method for controlling heat dissipation of a water-cooled power module is provided, such as Figure 4 As shown, the method includes:

[0041] Step S201: Obtain the first temperature of multiple functional units of the water-cooled power module when they are working; the above first temperature can be the current working temperature of the functional unit, which is obtained by directly detecting the functional unit by the temperature sensor; since the working temperature may be very high, the service life of the temperature sensor will be reduced, and the first temperature can also be set to the heat dissipation temperature taken away by the functional unit after water cooling, which is obtained by the difference detected by the temperature sensors of the water inlet and the water outlet; the heat dissipation temperature can also indirectly indicate the working temperature. When the heat dissipation temperature is too high, it also indicates that the working temperature is too high and more heat dissipation is required to maintain the normal working temperature. In the following text, whether the first temperature is understood in terms of heat dissipation temperature or working temperature, the logic is consistent. For example, the first temperatures of the first functional unit, the second functional unit and the third functional unit are Ta1, Tb1 and Tc1 respectively.

[0042] Step S202: Determine the temperature margin of each functional unit according to the first temperature and the preset temperature of each functional unit; the preset temperature of the functional unit can be set by a program, such as the preset temperatures of the first functional unit, the second functional unit and the third functional unit are Ta2, Tb2 and Tc2 respectively. The obtained temperature margin is the value of the preset temperature minus the first temperature, such as the temperature margins of the first functional unit, the second functional unit and the third functional unit are Ta3, Tb3 and Tc3 respectively.

[0043] Step S203: According to the order of the temperature margins of the plurality of functional units, the opening angle of the water flow regulating component of the water cooling system in the water-cooled power module corresponding to the plurality of functional units is controlled to adjust the heat dissipation degree of the plurality of functional units, wherein the larger the temperature margin of the functional unit, the larger or smaller the corresponding opening angle. The larger the temperature margin, the lower the operating temperature of the current functional unit, and the less demand for heat dissipation; the smaller the temperature margin, the higher the operating temperature of the current functional unit, and the greater the demand for heat dissipation.

[0044] The present application first obtains the heat dissipation temperature of the heat generated by multiple functional units in the water-cooled power module during operation, the heat dissipation temperature is the first temperature, the optimal operating temperature of the functional unit is set as the preset temperature, the temperature margin of each functional unit can be obtained according to the preset temperature and the obtained first temperature, the above temperature margin is sorted by size, and the current heat dissipation of each functional unit can be known according to the sorting result to control the water flow regulating component to control the water flow of each branch respectively, thereby reducing the difference in the operating temperature between the various functional units in the water-cooled power module. The problem that the water-cooled power module in the related art cannot balance the heat dissipation of multiple components therein is solved.

[0045] In an optional scheme, the above-mentioned obtaining of the first temperature of multiple functional units of the water-cooled power module when they are in operation includes: obtaining the second temperature of the water inlet and the third temperature of the water outlet of multiple branches in the above-mentioned water cooling system located on the multiple functional units, and determining the above-mentioned first temperature based on the above-mentioned second temperature and the above-mentioned third temperature.

[0046] In the above embodiment, the temperature sensor obtains the second temperature at the water inlet and the third temperature at the water outlet of each functional module, and the first temperature is obtained according to the difference between the second temperature and the third temperature. The first temperature represents the heat dissipation temperature of the functional module by the current branch. If the first temperature is higher, it indicates that the heat generation of the current functional unit is higher, and the obtained temperature margin is smaller.

[0047] In one alternative, Figure 5As shown, the above-mentioned control method also includes: when the temperature margins of multiple functional units are all greater than zero, judging whether the difference between the maximum temperature margin and the minimum temperature margin of the above-mentioned functional units meets the preset margin; when the judgment indication is yes, judging whether the first water flow regulating components of multiple branches in the above-mentioned water cooling system with the above-mentioned minimum temperature margin are fully opened; when it is judged that the above-mentioned first water flow regulating components are fully opened, according to the preset temperature and the above-mentioned maximum temperature margin, determining the reduced opening angle of the second water flow regulating components of the above-mentioned branch with the above-mentioned maximum temperature margin, and adjusting the above-mentioned second water flow regulating components according to the above-mentioned angle; when it is judged that the above-mentioned first water flow regulating components are not fully opened, controlling the above-mentioned first water flow regulating components to be fully opened.

[0048] In one alternative, Figure 5 As shown, when the temperature margins of multiple functional units are not all greater than zero, it is determined whether the difference between the maximum temperature margin and the minimum temperature margin of the above functional units meets the preset margin; when the judgment indication is yes, it is determined whether the first water flow regulating components of the multiple branches in the above water cooling system with the above minimum temperature margin are fully opened; when it is determined that the above first water flow regulating components are fully opened, according to the preset temperature and at least one of the above temperature margins greater than zero, the reduced opening angle of the third water flow regulating components of the above branches with at least one of the above temperature margins greater than zero is determined, and according to the above angle, the third water flow regulating components are adjusted; when it is determined that the above first water flow regulating components are not fully opened, the above first water flow regulating components are controlled to be fully opened.

[0049] In the above embodiment, Figure 5 As shown, firstly, the first temperatures Ta1, Tb1 and Tc1 of the plurality of functional units are obtained, the first temperature is calculated by the difference between the second temperature and the third temperature of the obtained functional unit, and according to the first temperature and the preset temperature, a plurality of temperature margins Ta2, Tb2 and Tc2 are determined; the temperature margins are sorted, and a first judgment step is performed: whether the minimum value of the sorted temperature margins is greater than 0 is judged, and when the first judgment result indicates yes, it indicates that the first temperatures of all the functional units are relatively lower than the preset temperature at this time, that is, it indicates that the heat dissipation of the functional units can basically meet the requirements, and the difference between the operating temperature of each functional unit and the preset temperature is relatively small; then a second judgment step is performed: whether the difference between any two values ​​of the plurality of temperature margins is greater than 5°, and when the second judgment result indicates no, it indicates that the first temperature of all the functional units is not much different from the preset temperature, that is, it indicates that the operating temperature of the functional units is relatively stable, and there is no need to adjust the water cooling system, and then the step of obtaining the plurality of first temperatures is returned to perform a new judgment.

[0050] When the second judgment result indicates yes, it indicates that the temperature margins between multiple functional modules are quite different, that is, the operating temperature of the functional module with the smallest temperature margin is relatively high; perform the third judgment step: determine whether the water flow regulating component with the minimum temperature margin is fully open. When the third judgment result indicates no, fully open the water flow regulating component to allow the water cooling system to better dissipate heat for the functional unit, and after a preset time period, return to the second judgment step to re-judge.

[0051] When the third judgment result indicates yes, it means that the heat dissipation treatment of the functional unit with the highest heat dissipation temperature (highest operating temperature) has been increased, and the heat dissipation treatment of the functional unit with the lowest heat dissipation temperature (lowest operating temperature) needs to be reduced so that more water cooling can be biased towards the functional unit with the highest operating temperature; calculate the closing angle of the water flow regulating component with the maximum temperature margin, and adjust the opening angle of the water flow regulating component with the maximum temperature margin according to the obtained closing angle, and after a preset time period, return to the second judgment step to re-judge.

[0052] When the first judgment result indicates no, it indicates that the heat dissipation temperature of the functional unit with the smallest temperature margin is higher than the preset temperature, that is, the operating temperature of the functional unit is very high; the fourth judgment step is performed: determine whether the water flow regulating component with the smallest temperature margin is fully opened. When the fourth judgment result indicates no, the water flow regulating component is fully opened to allow the water cooling system to better dissipate heat for the functional unit, and after a preset time period, return to the first judgment step to re-judge.

[0053] When the fourth judgment result indicates yes, it means that the heat dissipation treatment of the functional unit with the highest heat dissipation temperature (highest operating temperature) has been increased, and the heat dissipation treatment of the functional unit with the lowest heat dissipation temperature (lowest operating temperature) needs to be reduced so that more water cooling can be biased towards the functional unit with the highest operating temperature; calculate the closing angle of the water flow regulating component except the minimum temperature margin, and adjust the opening angle of the water flow regulating component except the minimum temperature margin according to the obtained closing angle, and after a preset time period, return to the first judgment step to re-judge.

[0054] The above is when the first judgment result indicates no, and there is a temperature margin less than 0. When there are multiple temperature margins less than 0, it is necessary to fully open the water flow regulating component with a temperature margin less than 0 to increase water cooling and heat dissipation, and reduce the opening angle of the water flow regulating component with a temperature margin greater than 0. For example, Ta2>0>Tb2>Tc2, reduce the opening angle of the water flow regulating component of the first functional unit, and fully open the water flow regulating components of the second and third functional units. The above situation is an extreme state with 3 functional units, ready to stop working at any time to prevent the water-cooled power module from being damaged.

[0055] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the principles of the present application shall be included in the protection scope of the present application.
