[0002] Thermal management systems are crucial for the safety of the entire vehicle and the comfort of its occupants, especially for new energy vehicles, where their importance is even greater. Currently, most new energy vehicles on the market require accurate thermal management of the battery, electric drive, and electronic control systems, as well as the passenger compartment, under different operating conditions. These systems often employ decentralized control, requiring multiple three-way or four-way valves to couple the battery, electric drive, and heating circuits. This necessitates numerous cooling pipes and supports, placing significant demands on the overall thermal management system's layout space. This increases manufacturing and installation costs and hinders precise control of the entire thermal management module. Summary of the Invention

[0010] In the above implementation process, the electric drive water inlet is integrated into the multi-channel plate along the third preset direction, and the electric drive water outlet is integrated into the multi-channel plate along the fourth preset direction.

[0012] In the above implementation process, the heating water inlet, the warm air outlet and the fourteenth flow channel are integrated into the multi-flow channel plate. The heating water inlet is distributed along the fifth preset direction, and the heating water inlet and the fourteenth flow channel are connected to the flow channels of the multi-flow channel plate.

[0013] In some embodiments, the thermal management integrated module further includes a battery cooler disposed on the second side. The multi-channel plate is provided with a battery cooling water inlet and a battery cooling water outlet. Both the battery cooling water inlet and the battery cooling water outlet are connected to the battery cooler. The battery cooling water inlet is connected to the twelfth channel, and the battery cooling water outlet is connected to the third channel.

[0014] In the above process, the battery cooler is integrated into the multi-channel plate, and the flow channels of the battery cooler and the multi-channel plate are connected, which can realize the energy transfer between the coolant system and the air conditioning system, improve the energy efficiency of the whole vehicle, and help reduce weight and cost, thus achieving overall lightweighting.

[0015] In some embodiments, the thermal management integrated module further includes a proportional valve disposed on the second side. The proportional valve is configured with an inlet end, a first outlet end and a second outlet end. The inlet end is connected to the eleventh flow channel, the first outlet end is connected to the twelfth flow channel and the second outlet end is connected to the thirteenth flow channel.

[0016] In the above implementation process, the proportional valve is integrated into the multi-channel plate and connected to the flow channels of the multi-channel plate. It can not only realize the reasonable distribution of coolant in different operating modes, thereby making energy transfer more reasonable and achieving the most efficient use of energy, but also realize the integrated control of the coolant system, reduce the flow path, reduce heat transfer loss, improve the overall energy efficiency, reduce costs, optimize the overall wiring harness routing, and help reduce weight and cost, thus achieving overall lightweighting.

[0017] In some embodiments, the thermal management integrated module further includes a heat dissipation water outlet, which is disposed on the first side and distributed along a seventh preset direction, and is connected to the eighth flow channel. This enables heat exchange management between the coolant system and the environment, reduces flow paths, lowers heat transfer losses, improves overall energy efficiency, and facilitates weight reduction and cost reduction, achieving overall lightweighting.

[0018] In some embodiments, the thermal management integrated module further includes an expansion tank, which is disposed at the upper end of the multi-channel plate and is connected to the first channel and the tenth channel respectively.

[0019] In the above process, the expansion tank is integrated into the upper part of the multi-channel plate. It can not only store and add coolant, contain air overflowing from the system assembly, and regulate the ultimate pressure of the system assembly, but also ensure that the coolant system operates within a reasonable pressure range. At the same time, it improves the integration of the overall structure, reduces transmission losses, and improves the overall energy efficiency.

[0020] In some embodiments, the thermal management integrated module further includes a control component, which includes a controller and a wiring harness. The controller is integrated at the upper end of the multi-channel plate and connected to the wiring harness. The wiring harness is connected to the multi-way valve, the proportional valve, and the water pump assembly.

[0021] In the above implementation process, the controller of the control component is integrated on the upper end of the multi-channel plate. The controller is used to receive control signals, and after calculation by the internal program, it sends corresponding control commands to the multi-way valve, proportional valve and water pump assembly through the wiring harness. At the same time, it receives the information fed back by the multi-way valve, proportional valve and water pump assembly, and feeds it back to the whole vehicle to ensure that the whole system can work according to the requirements of the whole vehicle.

[0022] In some embodiments, the thermal management integration module further includes a temperature sensing component disposed on the multi-channel plate for acquiring the temperature of the coolant passing through the temperature sensing component.

[0023] In the above implementation process, the temperature sensing component is integrated into the multi-channel plate, which can detect the temperature of the coolant and feed the temperature signal back to the controller through the wiring harness. The vehicle can control the thermal management integrated module based on the temperature signal and other signals, so as to achieve more reasonable energy transfer and achieve the most efficient energy utilization. At the same time, the overall wiring harness routing is optimized, which is conducive to weight reduction and cost reduction, and achieves overall lightweighting.

[0050] Example

[0051] A typical electric vehicle thermal management system comprises three independent systems: an electric drive cooling system, a power battery temperature control system (including heating and cooling systems), and a passenger compartment air conditioning system (refrigerant cooling, heat pump dual-mode, or refrigerant cooling and hot water heating modes). Multiple three-way or four-way valves are typically used to connect the coolant system (including the electric drive cooling system, battery temperature control system, and passenger compartment hot water heating system). A heat exchanger then couples the air conditioning system and the coolant system, allowing each component to operate at its optimal temperature. This improves the vehicle's energy efficiency under various operating conditions and extends its range. Existing automotive coolant systems typically include multiple water pumps, multiple water valves, and multiple heat exchangers. These components facilitate heat transfer between the battery system, electric drive system, radiator, and heater, ensuring that all vehicle components operate within a reasonable temperature range and guaranteeing the normal functioning of components and the entire vehicle.

[0052] In common integrated thermal management systems, physically, components such as water valves, water pumps, and heat exchangers are independently and separately arranged and fixed to the vehicle by brackets, and are connected to each other by complex pipelines. This makes the coolant system complex, occupies a large space, is heavy, has large heat loss during operation, and is costly. It is also complex to install and has low vehicle assembly efficiency. Electrically, each electrical component is independently controlled, the wiring harness is complex, and the cost of electronic components is high.

[0053] In view of this, such as Figures 1-14 As shown, in a first aspect, this application provides a thermal management integrated module, including: a multi-flow channel plate 100, a multi-way valve 200, and a water pump assembly 300. The multi-way valve 200 is connected to the multi-flow channel plate 100, and the water pump assembly 300 is integrated into the multi-flow channel plate 100, so that coolant can flow between the multi-flow channel plate 100 and the multi-way valve 200, and different operating modes can be realized by switching the multi-way valve 200 to meet the functional requirements of the vehicle.

[0054] Specifically, the multi-channel plate 100 is configured with a first side and a second side, which are distributed opposite to each other. The first side is configured with a first channel 101, a second channel 102, a third channel 103, a fourth channel 104, a fifth channel 105, a sixth channel 106, a seventh channel 107, an eighth channel 108, and a ninth channel 109, which are independent of each other. The second channel 102 is located between the first channel 101 and the third channel 103. The eighth channel 108 and the ninth channel 109 are located on the side of the first channel 101 away from the third channel 103. The fourth channel 104, the fifth channel 105, the sixth channel 106, the seventh channel 107, the eighth channel 108, and the ninth channel 109 are independent of each other. The sixth flow channel 106 and the seventh flow channel 107 are located on the side of the third flow channel 103 away from the first flow channel 101. The second side is equipped with four independent flow channels: a tenth flow channel 110, an eleventh flow channel 111, a twelfth flow channel 112, and a thirteenth flow channel 113. The tenth flow channel 110 is connected to the seventh flow channel 107, and the flow direction is from the tenth flow channel 110 to the seventh flow channel 107 (a one-way valve is configured between the tenth flow channel 110 and the seventh flow channel 107). The twelfth flow channel 112 is connected to the thirteenth flow channel. A multi-way valve 200 is located on the first side, and the multi-way valve 200 has a first inlet 201, a second inlet 202, and a third outlet 203. Water inlets 202, 203, 204, 205, 206, 207, 208, and 209 are provided. The first water inlet 201 is connected to the first flow channel 101; the second water inlet 202 is connected to the third flow channel 103; the third water inlet 203 is connected to the twelfth flow channel 112; the fourth water inlet 204 is connected to the sixth flow channel 106; the fifth water inlet 205 is connected to the fourth flow channel 104; the sixth water inlet 206 is connected to the seventh water inlet 207 (e.g., via a pipe); and the eighth water inlet 208 is connected to the ninth flow channel 109. The ninth water inlet 209 communicates with the eighth flow channel 108; the water pump assembly 300 includes a first water pump 301, a second water pump 302, and a third water pump 303 integrated into the multi-flow channel plate 100. The inlet 501 of the first water pump 301 is connected to the first flow channel 101, and the outlet of the first water pump 301 is connected to the second flow channel 102. The inlet 501 of the second water pump 302 is connected to the twelfth flow channel 112 and the thirteenth flow channel 113, respectively. The inlet 501 of the third water pump 303 is connected to the fourth flow channel 104, and the outlet of the third water pump 303 is connected to the fifth flow channel 105.

[0055] For example, the multi-channel plate 100 serves as a carrier for the thermal management integrated module, providing mounting and positioning for the multi-way valve 200 and the water pump assembly 300, and is fixed by bolts or screws. A support plate 124 is configured at the lower end of the multi-channel plate 100. A rubber damping pad 125 and a bushing 126 are configured on the support plate 124. The support plate 124 provides support for the thermal management integrated module to improve the strength and NVH performance of the thermal management integrated module. The support plate 124 is mounted on the vehicle body through the bushing 126 and the rubber damping pad 125 to reduce the vibration transmission between the thermal management module and the vehicle, thereby improving the NVH performance of the vehicle.

[0056] The multi-way valve 200, as the core of the thermal management integrated module, functions to switch modes and change the flow path of the coolant. The ports of the multi-way valve 200 can be connected in pairs through the channels on its valve core. The valve core can rotate around its axis, either clockwise or counterclockwise. The valve core of the multi-way valve 200 has 16 positions. Every 22.5° rotation switches the multi-way valve 200 to a different position, and the connection relationship of its ports changes accordingly. This alters the series and parallel connection relationship between the external coolant circuits, thus achieving the function of thermal management.

[0057] The first water pump 301, the second water pump 302, and the third water pump 303 of the water pump assembly 300 can have the same or different power outputs depending on the needs of the vehicle, thereby improving the adaptability of the thermal management integrated module. The first water pump 301 and the third water pump 303 are located on the front side of the multi-channel plate 100, and the second water pump 302 is located on the rear side of the multi-channel plate 100. The first water pump 301 is connected to the electric drive system 1200 (e.g., connected to it through the electric drive water inlet 117), the second water pump 302 is connected to the heating system 900 (e.g., connected to the heater 902 through the heating water inlet 119), and the third water pump 303 is connected to the power battery system 1300 (e.g., connected to it through the battery water inlet 118). The water pump assembly 300 is fixed to the multi-channel plate 100 by bolts, etc., and can pressurize the low-pressure coolant at its inlet and enter its outlet, thereby driving the coolant to circulate within the thermal management integrated module.

[0058] In the above implementation process, one side of the multi-channel plate 100 is equipped with a first channel 101, a second channel 102, a third channel 103, a fourth channel 104, a fifth channel 105, a sixth channel 106, a seventh channel 107, an eighth channel 108, and a ninth channel 109, while the other side is equipped with a tenth channel 110, an eleventh channel 111, a twelfth channel 112, and a thirteenth channel 113. A multi-way valve 200 is integrated into the multi-channel plate 100, and the multi-way valve 200 is equipped with a first inlet 201, a second inlet 202, a third inlet 203, a fourth inlet 204, a fifth inlet 205, a sixth inlet 206, and a seventh inlet 207. 7. The eighth water inlet 208 and the ninth water inlet 209, the water inlet of the multi-way valve 200 are connected to the flow channel of the multi-flow plate 100. The first water pump 301, the second water pump 302 and the third water pump 303 of the water pump assembly 300 are integrated into the multi-flow plate 100, which enables the coolant to flow between the multi-flow plate 100 and the multi-way valve 200, and is used for heat exchange between the air conditioning system 1100, the electric drive system 1200 and the power battery system 1300. The integration of multiple components makes the whole structure more streamlined and compact, reduces pipe connections and bracket installation, thereby reducing the flow path, reducing heat transfer loss, and also achieving weight reduction and cost reduction.

[0059] like Figures 1-6 As shown, the multi-channel plate 100 is further equipped with a battery water inlet 115 and a battery water outlet 116. The battery water inlet 115 is distributed along a first preset direction and is connected to the fifth channel 105. The battery water outlet 116 is distributed along a second preset direction and is connected to the sixth channel 106. For example, the battery water inlet 115 and the battery water outlet 116 are located on the right side of the multi-channel plate 100. The length directions of the battery water inlet 115 and the battery water outlet 116 can be configured to be the same (e.g., both the first and second preset directions are left-right) or different. The battery water inlet 115 and the battery water outlet 116 are used to connect to the battery system respectively.

[0060] In the above implementation process, the battery water inlet 115 is integrated into the multi-channel plate 100 along the first preset direction, and the battery water outlet 116 is integrated into the multi-channel plate 100 along the second preset direction. Both the battery water inlet 115 and the battery water outlet 116 are connected to the flow channels of the multi-channel plate 100, which can realize energy management of the power battery system 1300, reduce the flow path, reduce heat transfer loss, improve overall energy efficiency, and reduce cost.

[0061] like Figure 1 or Figure 3As shown, the multi-channel plate 100 is further equipped with an electric drive water inlet 117 and an electric drive water outlet 118. The electric drive water inlet 117 is distributed along a third preset direction and is connected to the second channel 102. The electric drive water outlet 118 is distributed along a fourth preset direction and is connected to the ninth channel 109. For example, the electric drive water inlet 117 and the electric drive water outlet 118 are disposed on the front side of the multi-channel plate 100, and the length directions of the electric drive water inlet 117 and the electric drive water outlet 118 can be configured to be the same (e.g., both the third preset direction and the fourth preset direction are front and back directions), or they can be different, etc. The electric drive water inlet 117 and the electric drive water outlet 118 are used to connect to the electric drive system 1200 respectively.

[0062] In the above implementation process, the electric drive water inlet 117 is integrated into the multi-channel plate 100 along the third preset direction, and the electric drive water outlet 118 is integrated into the multi-channel plate 100 along the fourth preset direction. Both the electric drive water inlet 117 and the electric drive water outlet 118 are connected to the flow channels of the multi-channel plate 100, which can realize energy management of the electric drive system 1200, reduce the flow path, reduce heat transfer loss, improve overall energy efficiency, and reduce costs.

[0063] like Figure 2 or Figure 4 As shown, the multi-channel plate 100 is also equipped with a heating water inlet 119, a warm air outlet 120, and a fourteenth channel 114. The heating water inlet 119 is distributed along a fifth preset direction and is connected to the fourteenth channel 114. The fourteenth channel 114 is connected to the outlet end of the second water pump 302. The warm air outlet 120 is distributed along a sixth preset direction and is connected to the eleventh channel 111. For example, the heating water inlet 119 is disposed on the right side of the multi-channel plate 100, and the length direction of the heating water inlet 119 may be consistent with the battery water inlet 115 and / or the battery water outlet 116 (e.g., the fifth preset direction is the left-right direction), or it may not be consistent, etc. The heating water inlet 119 is used to connect to the heater 902 of the heating system 900; the warm air outlet 120 is disposed on the rear side of the multi-channel plate 100, and the length direction of the warm air outlet 120 may be consistent with the electric drive water inlet 117 and / or the electric drive water outlet 118 (e.g., the sixth preset direction is the front-back direction), or it may not be consistent, etc. The warm air outlet 120 is used to connect to the warm air core 901 of the heating system 900.

[0064] In the above implementation process, the heating water inlet 119 and the fourteenth flow channel 114 are integrated into the multi-flow channel plate 100. The heating water inlet 119 is distributed along the fifth preset direction, and the heating water inlet and the fourteenth flow channel 114 are connected to the flow channels of the multi-flow channel plate 100. This enables energy management of the heater 902, reduces the flow path, reduces heat transfer loss, improves overall energy efficiency, and reduces costs.

[0065] Please refer to again Figure 2 and Figure 4 The thermal management integrated module also includes a battery cooler 400, which is disposed on the second side (i.e., the rear side of the multi-channel plate 100). The multi-channel plate 100 is provided with a battery cooling water inlet 121 and a battery cooling water outlet 122. Both the battery cooling water inlet 121 and the battery cooling water outlet 122 are connected to the battery cooler 400. The battery cooling water inlet 121 is connected to the twelfth channel 112, and the battery cooling water outlet 122 is connected to the third channel 103.

[0066] In the above implementation process, the battery cooler 400 is integrated into the multi-channel plate 100, and the flow channels of the battery cooler 400 and the multi-channel plate 100 are connected, which can realize the energy transfer between the coolant system and the air conditioning system 1100, reduce the flow path, reduce heat loss, improve the overall energy efficiency, and help reduce weight and cost, and achieve overall lightweighting.

[0067] Please refer to again Figure 2 and Figure 4 The thermal management integrated module further includes a proportional valve 500, which is disposed on the second side. The proportional valve 500 is configured with an inlet end 501, a first outlet end 502 and a second outlet end 503. The inlet end 501 is connected to the eleventh flow channel, the first outlet end 502 is connected to the twelfth flow channel, and the second outlet end 503 is connected to the thirteenth flow channel.

[0068] In the above implementation process, the proportional valve 500 is integrated into the multi-channel plate 100 and connected to the flow channels of the multi-channel plate 100. It can not only realize the reasonable distribution of coolant in different operating modes, thereby making energy transfer more reasonable and achieving the most efficient use of energy, but also realize the integrated control of the coolant system, reduce the flow path, reduce heat transfer loss, improve the overall energy efficiency, reduce costs, optimize the overall wiring harness routing, and help reduce weight and cost, thus achieving overall lightweighting.

[0069] like Figure 1 or Figure 3As shown, the thermal management integrated module also includes a heat dissipation outlet 123, which is disposed on the first side (front side). The heat dissipation outlet 123 is distributed along a seventh preset direction (e.g., along the front-to-back direction) and is connected to the eighth flow channel 108. This enables heat exchange management between the coolant system and the environment, reduces flow paths, lowers heat transfer losses, improves overall energy efficiency, and facilitates weight reduction and cost reduction, achieving overall lightweighting.

[0071] In the above process, the expansion tank 600 is integrated into the upper end of the multi-channel plate 100. It can not only store and add coolant, contain air overflowing from the system assembly, and regulate the ultimate pressure of the system assembly, but also ensure that the coolant system operates within a reasonable pressure range. At the same time, it improves the integration of the overall structure, reduces transmission losses, and improves the overall energy efficiency.

[0072] like Figure 1 As shown, the thermal management integrated module also includes a control component, which includes a controller 700 and a wiring harness 701.

The controller 700 is equipped with a power interface 702 and a communication interface 703. The wiring harness 701 is connected to the multi-way valve 200, the proportional valve 500, and the water pump assembly 300.

[0073] In the above implementation process, the controller 700 of the control component is integrated on the upper end of the multi-channel plate 100. The controller 700 is used to receive control signals and, after calculation by the internal program, send corresponding control commands to the multi-way valve 200, the proportional valve 500 and the water pump assembly 300 through the wiring harness 701. At the same time, it receives the information fed back by the multi-way valve 200, the proportional valve 500 and the water pump assembly 300 and feeds it back to the whole vehicle to ensure that the whole system can work according to the requirements of the whole vehicle.

[0074] like Figures 1-2As shown, the thermal management integrated module further includes a temperature sensing component, which is disposed on the multi-channel plate 100 to collect the temperature of the coolant passing through the temperature sensing component; wherein the temperature sensing component includes a first sensor, a second sensor and a third sensor, the first sensor and the third sensor are disposed on the front side of the multi-channel plate 100, the second sensor is disposed on the rear side of the multi-channel plate 100, the first sensor is disposed between the electric drive water inlet 117 and the first water pump 301, the third sensor is disposed between the battery water inlet 115 and the third water pump 303, and the second sensor is disposed between the battery cooler 400 and the third water inlet 203.

[0075] In the above implementation process, the temperature sensing component is integrated into the multi-channel plate 100, which can detect the temperature of the coolant and feed the temperature signal back to the controller 700 through the wiring harness 701. The vehicle can control the thermal management integrated module based on the temperature signal and other signals, so as to achieve more reasonable energy transfer and achieve the most efficient energy utilization. At the same time, the overall wiring harness 701 routing is optimized, which is conducive to weight reduction and cost reduction, and achieves overall lightweighting.

A water pump 301 is connected to the electric drive system 1200.

The multi-way valve 200 and the second water pump 302 of the thermal management integrated module are connected to the heating system 900. The heating system 900 includes a warm air core 901 and a heater 902. The warm air core 901 is connected to the heater 902 and a warm air outlet 120. The heater 902 is connected to the heating water inlet 119.
