[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] like Figures 1 to 12 As shown, the present application provides a thermal management device, which includes: a driver cooling assembly 20 for cooling the driver 22; a cooler 51 for heat exchange with the inside of the cockpit; a radiator 61 for heat exchange with the outside of the cockpit; a first multi-way valve 10, including multiple valve ports; wherein the output end of the driver cooling assembly 20 is respectively connected to the input end of the cooler 51 and the input end of the radiator 61, the output end of the cooler 51 and the output end of the radiator 61 are connected to the input end of the driver cooling assembly 20, and the output end of the driver cooling assembly 20, the input end of the cooler 51, and the input end of the radiator 61 are respectively connected to different valve ports of the first multi-way valve 10.

[0041] Through the above solution, the different waterways can be interconnected to achieve a variety of different operating modes, thereby meeting the user's usage needs. In this application, compared with the existing technology, new modes such as self-circulation of heat storage of the drive unit and direct heating of the battery by the waste heat of the drive unit are added to meet the user's usage needs as much as possible.

[0042] In this application, the driving element 22 is specifically a motor. Compared with the prior art, the above structure can avoid the cross-flow and heat generation of the two circuits of coolant when the battery active cooling and driving element cooling mode are in operation, thereby ensuring the stable operation of the system.

[0043] Optionally, the thermal management device further includes a heater 41 and a battery heat exchange assembly 30 for exchanging heat with the power battery 32. The input of the battery heat exchange assembly 30 is connected to the output of the heater 41.

The heater 41 can heat the battery to meet the needs of different operating conditions.

[0044] Optionally, the thermal management device further includes a second multi-way valve 11, the two ends of which are respectively connected to the output end of the battery heat exchange assembly 30 and the input end of the driver cooling assembly 20.

[0046] Optionally, the driver cooling assembly 20 includes a first water pump 21, a driver 22, and a first flow path 23. The first flow path 23 is located within the driver 22. The output end of the first water pump 21 is connected to the input end of the first flow path 23. The output end of the first flow path 23 forms the output end of the driver cooling assembly 20, and the input end of the first water pump 21 forms the input end of the driver cooling assembly 20. Alternatively, the output end of the first flow path 23 is connected to the input end of the first water pump 21.

This configuration can achieve different modes of the thermal management device to meet user requirements.

[0047] Optionally, the battery heat exchange assembly 30 includes a second water pump 31, a power battery 32, and a second flow path 33. The second flow path 33 is located within the power battery 32, and the output end of the second flow path 33 is connected to the input end of the second water pump 31. The output end of the second water pump 31 forms the output end of the battery assembly, and the input end of the second flow path 33 forms the input end of the battery assembly. Alternatively, the output end of the second water pump 31 is connected to the input end of the second flow path 33. The output end of the second flow path 33 forms the output end of the battery assembly, and the input end of the second water pump 31 forms the input end of the battery assembly. This configuration can achieve different modes of the thermal management device to meet user needs.

[0048] Optionally, one of the valve ports of the first multi-way valve 10 is simultaneously connected to the input end of the driver cooling assembly 20 and the output end of the radiator 61. This arrangement can achieve different modes of the thermal management device to meet user needs.

[0049] Optionally, the third multi-way valve 12 is used to interconnect at least two of the output ends of the heater 41, the cooler 51, and the radiator 61. This arrangement can achieve different modes of the thermal management device to meet user needs.

[0050] In one embodiment, the valve ports include a first valve port a, a second valve port b, a third valve port c, a fourth valve port d, a fifth valve port e, and a sixth valve port f. This arrangement allows the corresponding valve ports to be opened and closed according to actual usage requirements, thereby achieving different functions of the device and increasing the applicability of the device.

[0051] In one embodiment, the thermal management device features a self-circulating heat storage mode for the driver. When in this mode, coolant is pumped out by the first water pump 21, flows through the driver 22, and then sequentially exits through the fifth valve port e and the fourth valve port d before returning to the first water pump 21 to complete the cycle. This mode allows the driver to rapidly increase its coolant circulation temperature when insufficient residual heat is present in the low-temperature mode, thereby quickly bringing the driver to operating temperature.

[0052] In one embodiment, the thermal management device also has a driver waste heat heating battery mode. When in driver waste heat heating battery mode, coolant is pumped out by the first water pump 21, flows through the driver 22, absorbs heat from the driver 22, then exits through the fifth valve port e and the first valve port a, flows through the heater 41, enters the power battery 32 to heat the power battery 32, and then passes through the second water pump 31 and the open second multi-way valve 11 to return to the first water pump 21, completing the cycle. In this mode, when the power battery 32 requires heating, the heat generated by the driver can be used to directly heat the power battery 32, saving energy. If the heating demand of the power battery 32 increases further and the driver waste heat cannot meet the demand, the PTC heater can be activated to provide auxiliary heating.

[0053] In one embodiment, the thermal management device also has a driver cooling mode. When in driver cooling mode, coolant is pumped out by the first water pump 21, flows through the driver 22, absorbs heat from the driver 22, then passes through the fifth valve port e and the third valve port c, and dissipates the heat from the driver 22 to the outside air through the radiator 61. After dissipation, the coolant returns to the first water pump 21, completing the cycle. This prevents the driver from overheating and affecting normal vehicle operation.

[0054] In one embodiment, the thermal management device also features a driver component waste heat recovery and cabin heating mode. When in this mode, coolant is pumped out by the first water pump 21, flows through the driver component 22, absorbs heat from the driver component, then passes through the fifth valve port e and the second valve port b, and through the cooler 51 to release the coolant heat into the cabin. After flowing through the third multi-way valve 12, it returns to the first water pump 21 to complete the cycle. This mode recycles heat generated by the driver component, thereby reducing resource consumption of the thermal management device in heating mode and contributing to vehicle energy conservation.

[0055] In one embodiment, the thermal management device also has a mode for recovering waste heat from the driver to heat the battery and the cabin. When the thermal management device is in this mode, the coolant is pumped out by the first water pump 21, flows through the driver 22, absorbs heat from the driver 22, and then flows out through the fifth valve port e, exiting from the first valve port a and the second valve port b, respectively. This splits into two paths: one path passes through the cooler 51 to release the coolant's heat into the cabin, passes through the third multi-way valve 12, and returns to the first water pump 21 to complete the cycle. The other path passes through the heater 41 to heat the power battery 32, and finally returns to the first water pump 21 through the second water pump 31 and the open two-way valve to complete the cycle. This mode allows the heat generated by the driver to be recycled, allowing the driver coolant circulation temperature to be quickly increased when insufficient waste heat is generated in the low-temperature mode. It also reduces resource consumption of the thermal management device in the heating mode, contributing to vehicle energy conservation.

[0056] In one embodiment, the thermal management device also has an active battery cooling mode. When the thermal management device is in active battery cooling mode, the coolant is pumped out by the second water pump 31, then passes through the sixth valve port f and the second valve port b, flows through the cooler 51 to dissipate heat from the coolant, then passes through the third multi-way valve 12, flows through the power battery 32 to cool the power battery 32, and finally returns to the second water pump 31 to complete the cycle. In this arrangement, the coolant exchanges heat with the refrigerant through the cooler 51, and the refrigerant lowers the coolant temperature, thereby quickly reducing the temperature of the power battery 32 to meet user requirements.

[0057] In one embodiment, the thermal management device also has a battery passive cooling mode. When the thermal management device is in battery passive cooling mode, the coolant is pumped out by the second water pump 31, then passes through the sixth valve port f and the third valve port c, flows through the radiator 61 to dissipate heat from the coolant, then passes through the third multi-way valve 12, flows through the power battery 32 to cool the power battery 32, and finally returns to the second water pump 31 to complete the cycle. In this arrangement, the coolant exchanges heat with the outside air through the radiator 61, thereby reducing the temperature of the power battery 32 and reducing the energy consumption required for heat dissipation.

[0058] In one embodiment, the thermal management device also has an active battery cooling plus driver cooling mode. When in this mode, the device includes two coolant circulation lines. One coolant line is pumped out by the second water pump 31, then passes through the sixth valve port f and the second valve port b, flows through the cooler 51 to dissipate heat, then passes through the third multi-way valve 12, flows through the power battery 32 to cool the power battery 32, and finally returns to the second water pump 31 to complete the circulation. The other coolant line is pumped out by the first water pump 21, flows through the driver 22 to absorb heat, then passes through the fifth valve port e and the third valve port c, and dissipates the heat from the driver 22 to the outside air through the radiator 61. The heat dissipated coolant returns to the first water pump 21 to complete the circulation. This mode ensures that the driver and power battery 32 are maintained at normal operating temperatures, thereby facilitating stable operation of the thermal management device.

[0059] In one embodiment, the thermal management device also has a battery passive cooling plus driver cooling mode. When in this mode, the device includes two coolant circulation lines. One coolant line is pumped out by the second water pump 31, then passes through the sixth valve port f and the third valve port c, flows through the radiator 61 to dissipate heat, then passes through the third multi-way valve 12, flows through the power battery 32 to cool it, and finally returns to the second water pump 31 to complete the circulation. The other coolant line is pumped out by the first water pump 21, flows through the driver 22 to absorb heat, then passes through the fifth valve port e and the third valve port c, dissipates the heat from the driver 22 to the outside air through the radiator 61, and finally returns to the first water pump 21 to complete the circulation. This mode ensures that the driver and power battery 32 are maintained at normal operating temperatures, thereby facilitating stable operation of the thermal management device.

[0060] In one embodiment, the thermal management device also has a battery heating mode. When the thermal management device is in battery heating mode, the coolant is pumped out by the second water pump 31, then passes through the sixth valve port f and the first valve port a, flows through the heater 41, enters the power battery 32 to heat the power battery 32, and finally returns to the second water pump 31 to complete the cycle. This mode ensures that the power battery 32 is at a normal operating temperature, thereby facilitating the stable operation of the thermal management device. In this application, the power of the heater 41 can be selected to heat the coolant based on the heat required by the power battery 32.

[0061] In one embodiment, the thermal management device also has a driver waste heat cabin heating and driver cooling mode. When the thermal management device is in driver waste heat cabin heating and driver cooling mode, coolant is pumped out by the first water pump 21, flows through the driver 22, absorbs heat from the driver 22, and then flows out of the second valve port b and the third valve port c through the fifth valve port e, respectively, splitting into two paths. One path of coolant passes through the cooler 51 to release heat into the cabin, flows through the third multi-way valve 12, and returns to the first water pump 21 to complete the cycle. The other path of coolant passes through the radiator 61 to dissipate heat from the driver 22 to the outside air. The heat-dissipated coolant then returns to the first water pump 21 to complete the cycle. This mode heats the cabin while also reducing the temperature of the driver, thereby facilitating stable vehicle operation.
