[0050] Referring to Figures 1 - 4 and Figures 9 - 10 As shown, the radiator assembly 100 of the embodiments of the present invention is used for thermal management of the battery 45 and / or the motor and electronic control module 47.

[0051] The radiator assembly 100 includes: a first heat exchanger 10 and a valve housing 20.

[0052] The valve housing 20 is provided with a control valve 30 and a water pump 41. The water pump 41 is used to drive the coolant, and the control valve 30 is used to control the flow of the coolant in the first heat exchanger 10, the battery 45, and the motor electronic control module 47. Specifically, the control valve 30 can be a four-way valve. The control valve 30 is respectively connected to the first heat exchanger 10, the battery 45, and the motor electronic control module 47. The coolant in the first heat exchanger 10 can exchange heat with the external environment. The coolant absorbs heat after passing through the first heat exchanger 10, and the control valve 30 controls the heat-exchanged coolant to exchange heat with the motor electronic control module 47 or the battery 45. In addition, in some embodiments, a second heat exchanger 43 is also provided, and the control valve 30 controls the flow of the coolant in the second heat exchanger 43. The coolant in the second heat exchanger 43 can also exchange heat with the external environment, and the control valve 30 controls the heat-exchanged coolant to exchange heat with the motor electronic control module 47, the first heat exchanger 10, or the battery 45, etc.

[0053] In addition, the heat generated in the motor electronic control module 47 and the battery 45 can also control the flow direction of the coolant through the control valve 30 and transport it to different parts, realizing the thermal management of the battery 45 and the motor electronic control module 47. The functions that the radiator assembly 100 can achieve are increased, and the integration degree is improved.

[0054] Therefore, by controlling the flow of the coolant in the first heat exchanger 10, the battery 45, and the motor electronic control module 47 through the control valve 30, the thermal management of the battery 45 and the motor electronic control module 47 can be realized, and the integration degree of the radiator assembly 100 can be improved.

[0055] Refer to Figures 1 - 8 As shown, the first heat exchanger 10 includes a heat dissipation body 11 and a heat dissipation water chamber 12, and the heat dissipation water chamber 12 is communicated with the heat dissipation body 11.

[0056] Specifically, the body of the first heat exchanger 10 is used to dissipate heat. The coolant carrying heat flows through the first heat exchanger 10 and dissipates heat through the heat dissipation fins on the heat dissipation body 11. According to different usage environments, the heat dissipation fins on the heat dissipation body 11 can also absorb the heat in the environment and transfer it to the coolant in the first heat exchanger 10 to achieve heat management with different requirements. The coolant is stored in the heat dissipation water chamber 12, and the heat dissipation water chamber 12 is communicated with the heat dissipation body 11, which can evenly distribute the coolant to each heat dissipation tube of the first heat exchanger 10.

[0057] Among them, the heat dissipation water chamber 12 can be a plastic water chamber.

[0058] The heat dissipation water chamber 12 is arranged on one side of the heat dissipation body 11 in the first direction, and the valve housing 20 is arranged on one side of the heat dissipation water chamber 12 in the second direction. Specifically, the first direction can be the front-back direction, the heat dissipation water chamber 12 is arranged on the front side of the heat dissipation body 11, the second direction can be the up-down direction, and the valve housing 20 is arranged above the heat dissipation water chamber 12.

[0059] The control valve 30 is communicated with the heat dissipation water chamber 12, the water pump 41 and the battery 45. The valve housing 20 is arranged above the heat dissipation water chamber 12 and fixedly connected to the heat dissipation water chamber 12. A first flow channel 28 is arranged inside the valve housing 20 for the coolant to pass through. The first flow channel 28 inside the heat dissipation water chamber 12 and the valve housing 20 are communicated with each other. In this way, the coolant passing through the valve housing 20 can enter the heat dissipation water chamber 12 through the first flow channel 28 and then enter the first heat exchanger 10.

[0060] A first mounting hole 26 is also arranged on the valve housing 20. The water pump 41 is fixed above the valve housing 20 through the first mounting hole 26, and the water pump 41 is used to drive the coolant to flow.

[0061] The control valve 30 and the water pump 41 are arranged on one side of the valve housing 20 in the second direction, and the second heat exchanger 43 is arranged on the other side of the valve housing 20 in the second direction. The control valve 30 is communicated with the second heat exchanger 43.

[0062] That is, the second heat exchanger 43 is arranged below the valve housing 20. A second flow channel 29 is arranged inside the valve housing 20 for the coolant to pass through. A first communication port 121 is arranged on the heat dissipation water chamber 12. The first communication port 121 is communicated with the second heat exchanger 43 and is communicated with the second flow channel 29 inside the valve housing 20. In this way, the coolant passing through the valve housing 20 can enter the second heat exchanger 43 through the second flow channel 29 and pass through the first communication port 121 of the heat dissipation water chamber 12. In addition, a second communication port 122 is also arranged on the heat dissipation water chamber 12. The second communication port 122 is communicated with the second heat exchanger 43 and is communicated with the valve housing 20. The coolant in the second heat exchanger 43 can enter the valve housing 20 through the second communication port.

[0063] Wherein, the connection mode between the valve housing 20 and the heat dissipation water chamber 12 can be welding, and further, it can be friction welding.

[0064] Refer to Figures 1 - 2 and Figure 11As shown, the control valve 30 includes: a plurality of valve cores 31 and a driving member 32. A plurality of flow holes 25 are provided on the valve housing 20. Parts of the plurality of valve cores 31 are respectively arranged in the plurality of flow holes 25. The driving member 32 is used to control any one of the plurality of valve cores 31 to open the corresponding flow hole 25. Specifically, there may be four valve cores 31. Four flow holes 25 are provided on the valve housing 20. The lower parts of the four valve cores 31 are respectively arranged in the four flow holes 25. The driving member 32 is used to control whether the valve core 31 contacts the flow hole 25 of the valve housing 20. When the valve core 31 contacts the flow hole 25, the coolant cannot flow out of the flow hole 25. When the valve core 31 does not contact the flow hole 25, the coolant can flow out of the flow hole 25. The control valve 30 can individually control each valve core 31. In this way, the control valve 30 can control the flow direction of the coolant.

[0065] Among them, the driving member 32 can be a motor.

[0066] Referring to Figure 1 、 Figure 12 and Figure 13 As shown, the control valve 30 further includes: a transmission member 33. The transmission member 33 is clamped between the driving member 32 and the plurality of valve cores 31. The transmission member 33 is used to control any one of the valve cores 31 to open the corresponding flow hole 25. In this way, the driving member 32 provides a driving force to the transmission member 33. The transmission member 33 can individually control whether each valve core 31 contacts the flow hole 25, that is, control the valve core 31 to open or close the flow hole 25.

[0067] Specifically, the transmission member 33 can be a cam. The cam can rotate circumferentially. By rotating the cam to different positions, the flow hole 25 corresponding to the valve core 31 is opened.

[0068] Referring to Figures 14 - 15 As shown, an avoidance arc surface 331 is provided on one side of the transmission member 33 facing the plurality of valve cores 31. The avoidance arc surface 331 is used to avoid any one of the valve cores 31 so that any one of the valve cores 31 can open the corresponding flow hole 25. That is to say, during the rotation of the transmission member 33, when the valve core 31 corresponds to the position of the avoidance arc surface 331, the valve core 31 can move upward, so that the flow hole 25 is opened and the coolant can pass through. In other positions, the position of the valve core 31 is fixed and the flow hole 25 is closed, and the coolant cannot pass through.

[0069] Furthermore, referring to Figure 13 As shown, an avoidance arc surface 331 is provided on the surface of the transmission member 33 in contact with the valve core 31 every 60° from the initial position. Therefore, when the driving member 32 controls the transmission member 33 to rotate an integer multiple of 60° from the initial position, for example, rotate 120°, the flow hole 25 corresponding to the valve core 31 can be opened to allow the coolant to flow through the passage.

[0070] Referring to Figure 1 andFigure 11 As shown, the control valve 30 further includes: a plurality of elastic members 34, and the plurality of elastic members 34 respectively abut between the plurality of valve cores 31 and the heat dissipation water chamber 12. When the valve core 31 is opposite to the avoidance arc surface 331, the elasticity of the elastic member 34 can push the valve core 31 upward, so that the flow hole 25 is opened, allowing the coolant to flow through the passage. Specifically, the number of the elastic members 34 is the same as that of the valve cores 31, and can be four.

[0071] Among them, the elastic member 34 can be a spring.

[0072] Referring to Figures 1 - 2 As shown, the control valve 30 further includes: a valve cover 35, the valve housing 20 is fixed on the heat dissipation water chamber 12, a plurality of through holes 351 are provided on the valve cover 35, and the other parts of the plurality of valve cores 31 are respectively arranged in the plurality of through holes 351 and move up and down in the through holes 351, and the driving member 32 is fixed on the valve cover 35. Specifically, the driving member 32 is fixed on the valve cover 35, the transmission member 33 is clamped between the driving member 32 and the valve cover 35, the upper parts of the plurality of valve cores 31 pass through the through holes 351 on the valve cover 35, the transmission member 33 abuts against the valve cores 31 passing through the through holes 351, when the transmission member 33 rotates and the valve core 31 corresponds to the avoidance arc surface 331, it can move up and down in the through hole 351 of the valve cover 35, and the diameter of the through hole 351 is larger than the diameter of the valve core 31, which can enable the valve core 31 to move smoothly in the through hole 351.

[0073] Referring to Figures 9 - 10 As shown, a first water chamber 21 and a second water chamber 22 are arranged on one side of the valve housing 20 in the second direction, the first water chamber 21 and the second water chamber 22 are isolated from each other, the first water chamber 21 is communicated with the water pump 41, and the second water chamber 22 is communicated with the second heat exchanger 43; and, a third water chamber 23 and a fourth water chamber 24 are arranged on the other side of the valve housing 20 in the second direction, the third water chamber 23 and the fourth water chamber 24 are isolated from each other, the third water chamber 23 is communicated with the heat dissipation water chamber 12, and the fourth water chamber 24 is communicated with the battery 45.

[0074] Specifically, a first water chamber 21 and a second water chamber 22 are arranged on the side of the valve housing 20 facing the valve cover 35, and a third water chamber 23 and a fourth water chamber 24 are arranged on the side of the valve housing 20 facing the heat dissipation water chamber 12. That is to say, the first water chamber 21 and the second water chamber 22 are arranged on the front surface of the valve housing 20, and the third water chamber 23 and the fourth water chamber 24 are arranged on the back surface of the valve housing 20. At least two flow holes 25 are arranged in each water chamber. Among them, the first flow hole 251 of the first water chamber 21 is communicated with the second flow hole 252 of the third water chamber 23, the third flow hole 253 of the first water chamber 21 is communicated with the fourth flow hole 254 of the fourth water chamber 24, the fifth flow hole 255 of the second water chamber 22 is communicated with the sixth flow hole 256 of the third water chamber 23, and the seventh flow hole 257 of the second water chamber 22 is communicated with the eighth flow hole 258 of the fourth water chamber 24.

[0075] In this way, the coolant can be divided into four regions at the valve housing 20, and the flow directions of the coolant in each region are different. Specifically, the coolant can flow into the third water chamber 23 or the fourth water chamber 24. Also, since the first water chamber 21 is connected to the water pump 41, the second water chamber 22 is connected to the second heat exchanger 43, the third water chamber 23 is connected to the radiator water chamber 12, and the fourth water chamber 24 is connected to the battery 45, the coolant pumped out by the water pump 41 can enter the third water chamber 23 or the fourth water chamber 24 after passing through the first water chamber 21, and then enter the radiator water chamber 12 or the battery 45. The coolant in the second heat exchanger 43 can enter the second water chamber 22 and then enter the third water chamber 23 or the fourth water chamber 24, and then enter the radiator water chamber 12 or the battery 45. Similarly, the coolant passing through the radiator water chamber 12 and the battery 45 can also pass through the third water chamber 23 or the fourth water chamber 24, thereby realizing the circulation of the coolant and realizing functions such as natural heat dissipation, battery 45 cooling or heating, and heat pump waste heat recovery.

[0076] In some embodiments, the second heat exchanger 43 may not be provided, and the valve core 31 of the control valve 30 is reduced to three.

[0077] Refer to Figure 2 As shown, a three-way water channel 44 is provided between the water pump 41 and the control valve 30, and the three-way water channel 44 is respectively connected to the control valve 30, the water pump 41, and the second heat exchanger 43. That is, the coolant can select to flow to the control valve 30, the water pump 41, or the second heat exchanger 43 within the three-way water channel 44, further increasing the coolant flow channels and enabling the first heat exchanger 10 to integrate more functions.

[0078] Refer to Figures 1 - 2 and Figures 9 - 10 As shown, the radiator assembly 100 further includes: a temperature sensor 42, and the temperature sensor 42 is disposed within the three-way water channel 44. The temperature sensor 42 is responsible for measuring the coolant temperature. The temperature sensor 42 detects the coolant temperature pumped out by the water pump 41 and feeds back the detection result to the controller. The controller can determine how to control the valve core 31 of the control valve 30 to open or close the flow hole 25 according to the coolant condition, so as to select to realize functions such as natural heat dissipation, battery 45 cooling or heating, and heat pump waste heat recovery. Also, a second mounting hole 27 is provided on the valve housing 20, and the temperature sensor 42 is mounted in the second mounting hole 27.

[0079] According to the heat management system of the second aspect embodiment of the present invention, it includes a battery 45, an air conditioning system 46, and a radiator assembly 100.

[0080] The air conditioning system 46 includes a second heat exchanger 43. The second heat exchanger 43 can not only exchange heat with the coolant flowing out of the control valve 30, but also exchange heat with the air conditioning system 46 to realize various functions of the heat management system.

[0081] The motor and electric control module 47 is selectively connected to the first heat exchanger 10, and the control valve 30 is used to control the flow of the coolant in the first heat exchanger 10, the battery 45, the motor and electric control module 47, and the second heat exchanger 43.

[0082] Among them, referring to Figure 16 As shown, the air conditioning system 46 includes a compressor 461, a first condenser 462, a second condenser 463, and an evaporator 464. The compressor 461 compresses the refrigerant to make it a high-temperature gaseous refrigerant. The refrigerant circulates in the air conditioning system, thereby realizing the transfer and dissipation of heat. The first condenser 462 and the second condenser 463 can condense the refrigerant and release heat, and the temperature of the refrigerant decreases. The evaporator 464 can evaporate the refrigerant and absorb the surrounding heat, and the temperature of the refrigerant increases.

[0083] The evaporator 464, the second heat exchanger 43, the first condenser 462, and the second condenser 463 are all connected in series with the compressor 461. The refrigerant circulates in the air conditioning system 46. The refrigerant flowing out of the compressor 461 condenses and releases heat at the second condenser 463, and can enter the second heat exchanger 43 or the evaporator 464 to absorb heat, and then return to the compressor 461. Or the refrigerant flowing out of the compressor 461 condenses and releases heat at the first condenser 462, then enters the second heat exchanger 43 or the evaporator 464 to absorb heat, and then returns to the compressor 461. The first condenser 462 can be used when the load is low, and the second condenser 463 is used when the load is high.

[0084] Since the coolant also flows through the second heat exchanger 43, heat exchange occurs between the refrigerant and the coolant at the second heat exchanger 43.

[0085] The motor and electric control module 47 is connected to the first heat exchanger 10, and the coolant can absorb heat through the motor and electric control module 47 and then bring the heat into the first heat exchanger 10.

[0086] Through the cooperation of the radiator assembly 100, the air conditioning system 46, and the motor and electric control module 47, working modes such as battery 45 cooling, battery 45 heating, natural heat dissipation of the motor and electric control module 47, and heat pump + waste heat recovery can be achieved. The following refers to Figures 17 - 20 for a detailed description.

[0087] Battery 45 cooling mode:

[0088] Referring to Figure 17As shown, the control valve 30 controls the valve core 31 corresponding to the seventh flow hole 257 of the second water chamber 22 to move upward. The seventh flow hole 257 is communicated with the eighth flow hole 258 of the fourth water chamber 24. The low-temperature coolant flows to the battery 45 to absorb heat. The heated coolant then enters the inlet of the water pump 41. The coolant enters the second heat exchanger 43 through the control valve 30 for heat exchange. The temperature of the coolant decreases. The control valve 30 controls the valve core 31 corresponding to the seventh flow hole 257 of the second water chamber 22 to move upward. The seventh flow hole 257 is communicated with the eighth flow hole 258 of the fourth water chamber 24.
