[0035] The following description, in conjunction with the accompanying drawings, introduces a thermal management unit provided by an embodiment of this application. The thermal management unit of this application is particularly suitable for scenarios where energy storage liquid cooling units regulate temperature.

[0036] Please refer to Figure 1-6 This application provides a thermal management unit, which includes: a first partition 11, a second partition 12, a battery-side heat exchange pipeline 2, an energy storage-side heat exchange pipeline 3, and a fan; the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3 are housed in a space between the opposing first partition 11 and the second partition 12, the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3 are located on one side of the first partition 11, and the fan is located on the other side of the first partition 11; the battery-side heat exchange pipeline 2 includes a first liquid inlet 221 and a first liquid outlet 222, and the energy storage-side heat exchange pipeline 3 includes a second liquid inlet 321 and a second liquid outlet 322. The first liquid inlet 221, the first liquid outlet 222, the second liquid inlet 321, and the second liquid outlet 322 are located in the space near one end of the second partition 12, and are distributed at both ends of the second partition 12. In this way, the fan is set on one side relative to the housing space, forming an independent airflow channel, ensuring that the cooling airflow can effectively pass through the heat exchange pipes 3 of the battery end and the energy storage end, thereby achieving more efficient heat exchange; the battery end and the energy storage end are respectively provided with independent liquid inlet and liquid outlet, and are distributed near the end of the second partition 12, thereby effectively utilizing the space, reducing the area occupied by each component, and improving the space utilization rate.

[0037] Specifically, the first partition 11 and the second partition 12 isolate the thermal management unit into a first zone, a second zone, and a third zone. The second zone is located between the first and third zones. The first zone is used to house the fan, the second zone is used to house the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3, and the third zone is used to house the battery pack and the energy storage device. Both the energy storage-side heat exchange pipeline 3 and the battery-side heat exchange pipeline 2 are used to connect to the client-side pipeline, which includes the battery pack and the energy storage device.

[0038] Specifically, the second partition 12 includes a first mounting position, a second mounting position, and a ventilation screen. A first liquid inlet 221, a second liquid inlet 321, and a second liquid outlet 322 are located at the first mounting position, and the first liquid outlet 222 is located at the second mounting position. The ventilation screen is positioned between the first and second mounting positions. By placing the ventilation screen between the first and second mounting positions, the airflow generated by the fan can be evenly distributed, forming a stable airflow channel and effectively promoting heat exchange. The liquid inlet and outlet are located at two different mounting positions, fully utilizing the space of the second partition 12 and improving the stability of the thermal management unit.

[0039] Specifically, the first mounting position is on the right side of the second partition 12, and the second mounting position is on the left side of the second partition 12. The ventilation mesh is set between the first and second mounting positions to prevent ventilation dead zones within the thermal management unit. The plane of the first partition 11 is parallel to the plane of the second partition 12. A fan mounting position is provided on the first partition 11.

[0040] Specifically, the battery-side heat exchange pipeline 2 includes a battery-side controller, and the energy storage-side heat exchange pipeline 3 includes an energy storage-side controller 31. The battery-side controller 21 and the energy storage-side controller 31 are disposed in the accommodating space near the first partition 11, with the battery-side controller 21 and the energy storage-side controller 31 arranged adjacent to each other. In this way, the controllers are placed close to the first partition 11, reducing the complexity of management and layout. When the cooling airflow passes through the first partition 11, it can carry away the heat generated by each controller, thereby improving the overall heat dissipation efficiency of the system.

[0041] Specifically, the edge of the battery-side controller 21 is provided with a first interface for connecting to the battery-side heat exchange pipeline 2, and the edge of the energy storage-side controller 31 is provided with a second interface for connecting to the energy storage-side heat exchange pipeline 3. The first and second interfaces are located on the same side. Both the battery-side controller 21 and the energy storage-side controller 31 are vertically arranged, that is, the plane of the battery-side controller 21 is parallel to the plane of the first partition 11.

[0042] Furthermore, the thermal management unit also includes a fixed pressure plate; at least one of the first liquid inlet 221, the first liquid outlet 222, the second liquid inlet 321, and the second liquid outlet 322 is fixedly connected to the second partition 12 via the fixed pressure plate. The fixed pressure plate provides additional mechanical support, enhances the connection strength between each pipe and the second partition 12, and prevents loosening of connections or liquid leakage due to external forces or vibrations. The use of the fixed pressure plate can effectively improve the seismic resistance and fatigue resistance of the thermal management unit.

[0043] In this embodiment, the first water inlet pipe where the first liquid inlet is located, the first water outlet pipe where the first liquid outlet is located, the second water inlet pipe where the second liquid inlet is located, and the second water outlet pipe where the second liquid outlet is located are installed at their respective mounting positions on the second partition. By setting fixed pressure plates at each mounting position on the second partition, each pipe is fixedly connected to the second partition.

[0044] Specifically, the fixed pressure plate includes a first pressure plate and a second pressure plate, which are respectively disposed on the two side plates of the second partition.

[0045] In this embodiment, there is a first distance between the energy storage controller 31 and the first partition 11, and a second distance between the battery controller 21 and the first partition 11. The first distance is less than the second distance.

[0046] Furthermore, the thermal management unit also includes a battery pack and an energy storage device; a first liquid outlet 222 is connected to the battery pack, and a second liquid outlet 322 is connected to the energy storage device; a first partition 11 is disposed between the battery pack and the battery-side heat exchange pipeline 2, and also between the energy storage device and the energy storage-side heat exchange pipeline 3. This separation of the battery pack and energy storage device from their corresponding heat exchange pipelines effectively reduces heat transfer during the heat exchange process, ensuring that the battery pack and energy storage device operate within a safe temperature range. The first liquid outlet 222 and the second liquid outlet 322 are respectively connected to the battery pack and the energy storage device, ensuring that the cooling medium directly enters the target component after passing through the corresponding heat exchange pipelines, achieving rapid heat transfer and dissipation.

[0047] Specifically, the first liquid outlet 222 and the first liquid inlet 221 are provided with NW26 connectors to connect to the battery pack; the second liquid outlet 322 and the second liquid inlet 321 are provided with CQC18 connectors to connect to the energy storage device; the first partition 11 is provided with a support member, which can be fixedly connected to the connectors of each pipeline.

[0048] Furthermore, the thermal management unit also includes a replenishment pipeline 4, which is connected to the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3, respectively. The replenishment pipeline 4 includes a replenishment port 41, which is adjacent to the first outlet 222. Thus, the replenishment pipeline 4 is directly connected to the heat exchange pipelines at both the battery and energy storage ends, enabling the cooling system to quickly replenish the cooling medium. This avoids reduced heat dissipation performance or overheating due to insufficient liquid level, thereby ensuring normal system operation and temperature control. Because the replenishment port 41 is close to the outlet, it more effectively prevents air from being introduced during the replenishment process, thus preventing the accumulation of air bubbles in the heat exchange pipeline.

[0049] Specifically, a replenishment valve is provided on the replenishment pipeline 4. By opening the replenishment valve, the cold medium enters the battery end heat exchange pipeline 2 and / or the energy storage end heat exchange pipeline 3 through the replenishment pipeline. The replenishment pipeline 4 is located on the side close to the first partition 11.

[0050] In one embodiment, the first inlet pipe where the first inlet is located, the first outlet pipe where the first outlet is located, the second inlet pipe where the second inlet is located, the second outlet pipe where the second outlet is located, and the replenishment pipe where the replenishment port is located are all installed at their respective mounting positions on the second partition. By setting a fixed pressure plate at each mounting position on the second partition, each pipe is fixedly connected to the second partition.

[0051] Specifically, the replenishment pipeline 4 includes a first replenishment pipeline 42 and a second replenishment pipeline 43. The first replenishment pipeline 42 is connected to the battery-side heat exchange pipeline 2, and the second replenishment pipeline 43 is connected to the energy storage-side heat exchange pipeline 3. The first replenishment pipeline 42 and the second replenishment pipeline 43 are arranged alternately. In this way, the separation of the first replenishment pipeline 42 and the second replenishment pipeline 43 can effectively prevent cross-contamination of the cooling medium at the battery end and the energy storage end during the replenishment process, ensure the cleanliness of the cooling systems at both ends, and also optimize the pipeline layout.

[0052] Understandably, existing thermal management units often have four-way valves, eight-way valves, etc., installed in their heat exchange pipelines to regulate temperature, but they are essentially a single heat exchange pipeline. This application has two independent sets of pipelines, namely the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3, which improves the reliability of the entire thermal management unit.

[0053] Specifically, both the first replenishment pipe 42 and the second replenishment pipe 43 are flexible pipes. In one possible embodiment, the first replenishment pipe 42 and the second replenishment pipe 43 are arranged in parallel, and both are located below the first outlet 222.

[0054] Furthermore, the thermal management unit also includes a common heat exchanger 24, which is connected to both the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3. The common heat exchanger 24 reduces the complex piping connections required by independent heat exchangers, making the piping layout more compact, simplifying the structural design, and helping to reduce the weight of the thermal management unit.

[0055] Specifically, in the battery-side heat exchange pipeline 2, the first pump body 23 is connected to the common heat exchanger 24 through the first rigid pipe. The outlet of the common heat exchanger 24 is connected to the plate heat exchanger 25 through the second rigid pipe. The outlet of the first pump body 23 is connected to the battery-side controller 21 and the plate heat exchanger 25 respectively. The outlet on the same side of the plate heat exchanger 25 is connected to the PTC heater. In the energy storage-side heat exchange pipeline 3, the second pump body 33 is connected to the energy storage-side controller 31 and the common heat exchanger 24 through the third and fourth rigid pipes respectively. An actuator is provided on the second valve 34, which is used to control the opening degree of the second valve 34.

[0056] Specifically, the battery-side heat exchange pipeline 2 includes a first pump body 23, a plate heat exchanger 25, a heating device 26, and a first valve 27. The first pump body 23, the common heat exchanger 24, the plate heat exchanger 25, and the heating device 26 are connected in sequence. The first valve 27 is located between the common heat exchanger 24 and the battery-side controller 21. The first valve 27 is used to control the connection state between the battery-side controller 21 and the common heat exchanger 24. In this way, the first valve 27 can independently control the connection state between the battery-side controller 21 and the common heat exchanger 24, thereby flexibly adjusting the flow path of the cold medium. When rapid temperature adjustment is required, the introduction of the valve can effectively guide the fluid to preferentially pass through the common heat exchanger 24 or the plate heat exchanger 25, ensuring that the heat exchange efficiency of the system is maximized, allowing the battery to operate within the optimal temperature range.

[0057] Specifically, the battery-side heat exchange pipeline 2 includes a pressure sensor holder, a pressure sensor, a temperature sensor holder, a temperature sensor, a filter, a first pump body 23, a common heat exchanger 24, a first valve 27, a plate heat exchanger 25, a battery-side controller 21, a heating device 26, and an expansion tank 28. The pressure sensor holder is used to install the pressure sensor, the temperature sensor holder is used to install the temperature sensor, and the first valve 27 is a switch-type three-way valve, that is, the first valve 27 is used to adjust the opening and closing state of the battery-side controller 21 and the battery-side heat exchange pipeline 2.

[0058] Specifically, pressure sensors and temperature sensors are installed on the heat exchange pipeline 2 at the battery end near the first liquid inlet 221 and near the first liquid outlet 222.

[0059] Specifically, the battery-side heat exchange pipeline 2 includes a replenishment branch and an expansion tank 28. The expansion tank 28 is installed on the replenishment branch, which is connected to the battery-side heat exchange pipeline 2. The expansion tank 28 is located adjacent to the first pump body 23. In this way, the expansion tank 28 effectively collects and releases air within the system during the replenishment process, thereby reducing bubble formation, preventing cavitation, and improving the stability of the coolant circulation. The installation of the expansion tank 28 on the replenishment branch and its proximity to the first pump body 23 reduces the need for additional piping, making the system structure more compact, easier to install and maintain, and saving space and cost.

[0060] Specifically, the expansion tank 28 is used to replenish the liquid in the battery-side heat exchange pipeline 2. The expansion tank 28 has a volume of 1L and is installed on the pipeline between the heating device 26 and the first liquid outlet 222. The expansion tank 28 is also installed on the energy storage-side heat exchange pipeline 3, and the specifications of the expansion tanks 28 in the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3 are the same.

[0061] Specifically, the energy storage end heat exchange pipeline 3 includes a second pump body 33 and a second valve 34. The second pump body 33 is connected to the common heat exchanger 24, and the second valve 34 is installed on the pipeline between the common heat exchanger 24 and the energy storage end controller 31. The second valve 34 is used to regulate the connection state between the second pump body 33 and the energy storage end controller 31. By controlling the connection state between the common heat exchanger 24 and the energy storage end controller 31, the thermal management unit can effectively manage the flow rate of the coolant. When the cooling demand is low, the second valve 34 can be closed or partially closed, thereby reducing unnecessary fluid circulation, reducing the workload of the pump body, saving energy consumption, and extending the service life of the pump body. The second valve 34 isolates the pipeline between the energy storage end controller 31 and the common heat exchanger 24, allowing for quick cutoff of the liquid flow during maintenance or repair, facilitating segmented maintenance of the system without affecting the normal operation of other circuits.

[0062] Specifically, the energy storage end heat exchange pipeline 3 includes a pressure sensor holder, a pressure sensor, a temperature sensor holder, a temperature sensor, an expansion tank 28, a filter, a second pump body 33, a common heat exchanger 24, a second valve 34, an energy storage end controller 31, an automatic exhaust valve, and a drain valve. The pressure sensor holder is used to install the pressure sensor, the temperature sensor holder is used to install the temperature sensor, and the second valve 34 is a proportional three-way valve. That is, the first valve 27 is used to adjust the ratio of the coolant between the energy storage end controller 31 and the energy storage end heat exchange pipeline 3.

[0063] The following describes the disassembly and assembly process of the thermal management unit in this application embodiment, using a specific application scenario as an example:

[0064] First, a first partition 11 and a second partition 12 are installed in the frame of the thermal management unit. Components such as a common heat exchanger 24, a plate heat exchanger 25, a first pump body 23, and a second pump body 33 are installed in the accommodating space formed by the first partition 11 and the second partition 12.

[0065] Then, the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3 are respectively installed in the accommodating space, and connected to the common heat exchanger 24, plate heat exchanger 25, first pump body 23, second pump body 33, first valve 27 and second valve 34. Temperature sensors and water pressure sensors are installed on the battery-side heat exchange pipeline 2 and the energy storage-side heat exchange pipeline 3.

[0066] Finally, install the fan in the first area, install the battery pack and energy storage device in the third area, connect the battery pack and battery end heat exchange pipe 2, connect the energy storage device to the energy storage end heat exchange pipe 3, and then assemble the thermal management unit frame.

[0067] The following describes specific embodiments of this application based on the above technical solution.
