Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing and other fields that require thermal management, and specifically to a thermal management integrated module. Background Technology

[0002] The requirements for thermal management in new energy vehicles have increased significantly. These requirements must consider heat dissipation from the three core electrical components (battery, motor, and electronic control system), winter heating for the battery and cabin, and minimizing power consumption, space occupation, and production costs of various components. Therefore, integrated thermal management modules have emerged. These modules integrate components such as water pumps and valves through flow channels, significantly improving the problems of space occupation, difficult disassembly and assembly, and high costs associated with separate components.

[0003] However, current thermal management integrated modules still have the following problems: 1. The space can still be further compressed; 2. There are still too many wire harnesses, posing reliability and cost issues; 3. Under the condition of using domain control technology, the existing technology still requires the configuration of the conversion circuit board for water pump and water valve, which is not conducive to reducing costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 As shown, an embodiment of this utility model provides a thermal management integrated module, including a water pump, a water valve, a flow channel plate 1, and a housing 2. The flow channel plate 1 has multiple flow channels 10 formed thereon for corresponding communication with the water pump and the water valve. The water pump provides flow power to the fluid within the flow channels 10 to drive the fluid to flow within the flow channels 10. The water valve switches the communication relationship between the multiple flow channels 10, thereby realizing various different communication modes required for thermal management.

[0020] A water pump typically includes a power unit 5 (drive structure such as a motor), a pump body 8 (hydraulic mechanical structure such as an impeller), and a controller. A water valve typically includes an actuator 6 (drive structure such as a motor), a valve body 9 (water circuit switching structure such as a valve body and opening / closing components), and a controller.

[0021] The housing 2 is integrally formed and equipped with a cover plate 3 for sealing the housing 2. The housing 2 and the cover plate 3 can define a sealed accommodating cavity 4. The power unit 5 of the water pump, the actuator 6 of the water valve, the controller of the water pump, and the controller of the water valve are all installed in the accommodating cavity 4 (the housing 2 is provided with corresponding mounting seats). The controller of the water pump and the controller of the water valve can be multiple independently set PCB boards 7, or they can be integrated on a single PCB board 7.

[0022] The power unit 5 of the water pump, the actuator 6 of the water valve, the controller of the water pump and the controller of the water valve are all encapsulated in the accommodating cavity 4. This not only ensures that it can work in a dry environment, but also further reduces space, reduces connecting harnesses and adapter circuit boards, improves reliability and effectively reduces costs.

[0023] Furthermore, components that need to come into contact with fluid, such as the pump body 8 of the water pump and the valve body 9 of the water valve, can be installed on the back of the housing 2 (the side facing away from the cover plate 3) so as to connect with the corresponding components in the accommodating cavity 4. Components that need to be connected through the housing, such as the rotating shaft, need to be sealed with a sealing ring between the housing 2 to prevent fluid from leaking into the accommodating cavity 4 through the gap between the housing and the casing.

[0024] Alternatively, some of the flow channels 10 can be arranged on the back of the housing 2, which can make full use of the space on the back of the housing 2 and facilitate the connection between the water pump, water valve and the corresponding flow channel 10.

[0025] To reduce the axial height of the thermal management integrated module, the flow channel plate 1 can be mounted on the back of the housing 2, forming a space between the flow channel plate 1 and the housing 2 to accommodate the pump body portion 8 of the water pump and the valve body portion 9 of the water valve. Of course, the flow channel plate 1 can also be mounted in other positions, as long as the corresponding flow channel 10 on the flow channel plate 1 can communicate with the water pump and the water valve.

[0026] One or more flow channels 10 can be formed on the flow channel plate 1 according to the actual flow requirements of the fluid; or the shell 2 can be combined with other shells or plates to form one or more flow channels 10, thereby further reducing the axial height of the thermal management integrated module.

[0027] Ideally, all water connection ports 11 of the flow channel 10 should be located on the side of the flow channel plate 1 facing the shell 2. This allows the space on the other side of the flow channel plate 1 to be used to install the plate heat exchanger 12, providing the maximum usable area for the plate heat exchanger 12. This significantly reduces the height of the plate heat exchanger 12, thereby further compressing the axial height of the thermal management integrated module. An expansion valve 13 is installed on the side of the plate heat exchanger 12 facing the shell 2. The controller of the expansion valve 13 is also located in the accommodating cavity 4 and can be a separate PCB board 7, or it can be integrated with the controller of the water pump and the controller of the water valve on a single PCB board 7.

[0028] In addition, the electrical connector 14 is located on the housing 2. If the water connection port 11 and the electrical connector 14 are located on the same side, then the other side does not need wrench space (space for installation), so that the thermal management integrated module can be arranged at the edge of the cabin to improve the space utilization of the cabin.

[0029] Furthermore, temperature sensors and / or pressure sensors 15 can also be integrated and installed within the accommodating cavity 4, so that the temperature sensors and / or pressure sensors can be connected to the PCB board 7, thereby further reducing the external connection harness. The detection end of the temperature sensor and / or pressure sensor can be directly inserted into the flow channel 10 through the housing 2 for detection, and a sealing ring should also be provided at the penetration point for sealing.

[0030] Existing thermal management integrated modules, such as those disclosed in Chinese patents CN218367326U, CN119734561A, and CN119682523A, have independent encapsulation structures for their water pumps and water valves, each encapsulating a separate controller. Therefore, sufficient installation space needs to be reserved for the water pumps and water valves, and there are many connecting wire harnesses between the components. Under the condition of using domain control technology, adapter circuit boards for the water pumps and water valves also need to be configured.

[0031] This embodiment of the invention eliminates the original independent packaging structure of the water pump and water valve, encapsulating the power unit 5 of the water pump, the actuator 6 of the water valve, the controller of the water pump, and the controller of the water valve within the same housing 2. This further reduces space, wiring harnesses, and adapter circuit boards, improving reliability while lowering costs. Furthermore, this embodiment places the water pump, water valve, and water connection port 11 on the same side, maximizing the usable area for the plate heat exchanger 12, thus significantly reducing its height. It also eliminates the need for wrench space on the other side, facilitating the placement of the thermal management integrated module at the edge of the engine compartment.

[0032] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this utility model. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
