Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a structure for reducing oil accumulation and oil return in a thermal management system. Background Technology

[0002] In integrated module applications, existing integrated module solutions are widely used to achieve centralized control and management of fluid systems. However, the existing structure has certain drawbacks: the one-way valve is located below the integrated component, resulting in a long flow channel between the one-way valve outlet and the gas-liquid separator inlet, with a height difference. This structure causes oil to easily accumulate at the one-way valve outlet, affecting the normal operation of the system and the rational distribution of oil. At the same time, in actual use, due to the complex structure and valve layout, if oil accumulation persists for a long time, it will increase equipment maintenance costs and reduce system efficiency and stability.

[0003] Therefore, in order to solve the above problems, how to design a structure to reduce oil accumulation and oil return in the thermal management system is a technical problem that the industry urgently needs to solve. Utility Model Content

[0004] The purpose of this invention is to provide a structure that reduces oil accumulation and oil return in the thermal management system, thereby solving the oil accumulation problem mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A structure for reducing oil accumulation and return in a thermal management system includes a solenoid valve, an inlet on one side of the solenoid valve, an integrated module on one side of the solenoid valve, and a flow channel plate. The lower part of the side of the flow channel plate is connected to the side of the solenoid valve. The flow channel plate has a flow channel cavity that communicates with the inlet. A mounting bracket is provided on the upper surface of the flow channel plate. A guide cavity is provided in the mounting bracket that communicates with the flow channel cavity. The lower part of the side of the mounting bracket has an inlet that communicates with the guide cavity. A one-way valve is provided at the top of the guide cavity.

[0006] Preferably, the mounting bracket is provided with a gas-liquid separator on its side, and a discharge port is provided on the upper part of the side of the mounting bracket.

[0007] Preferably, a refrigerator is provided on one side of the flow channel plate, and a second flow channel plate is provided on the upper part of the side of the refrigerator. The lower part of the side of the second flow channel plate is connected to the upper part of the side of the refrigerator through an electronic expansion valve of the refrigerator. A second outlet is provided inside the second flow channel plate.

[0008] Preferably, a water-cooled condenser is provided on the lower part of both sides of the flow channel plate, and an oil cooler heat exchanger interface is provided on the upper part of the side of the water-cooled condenser, and a connecting interface is provided on the oil cooler heat exchanger interface.

[0009] Preferably, the lower side of the water-cooled condenser is provided with a water-cooled condenser heat exchanger interface, and the water-cooled condenser heat exchanger interface is provided with a second interface. The water-cooled condenser heat exchanger interface and the oil cooler heat exchanger interface are connected through a second solenoid valve.

[0010] The beneficial effects of this utility model are: 1. By placing the check valve at the top of the mounting bracket's flow guide chamber, the flow path distance between the check valve outlet and the gas-liquid separator inlet is shortened, optimizing the height difference issue. This design avoids the oil accumulation at the check valve outlet found in traditional structures, allowing the oil to flow smoothly with the refrigerant to the gas-liquid separator. This ensures that the fluid within the system circulates along the designed path, eliminating the obstruction of fluid flow by accumulated oil. This, in turn, guarantees the service life of the structure that reduces oil accumulation and return in the thermal management system, while also ensuring operational efficiency.

[0014] See Figures 1-5 This utility model provides a structure for reducing oil accumulation and return in a thermal management system, including a solenoid valve 1.

The lower part of the side of the mounting bracket 3 has an inlet 33 that communicates with the guide cavity 35. The top of the guide cavity 35 has a one-way valve 31. A portion of the refrigerant enters the solenoid valve 1 through inlet 11, then enters the flow channel cavity 21 of the flow channel plate 2 through the solenoid valve 1, and then enters the guide cavity 35 of the mounting bracket 3. After that, it is discharged through the one-way valve 31. Another portion of the refrigerant enters the guide cavity 35 through inlet 2 33, and is then discharged under the control of the one-way valve 31.

[0015] Specifically, the mounting bracket 3 has a gas-liquid separator 4 on its side, and an outlet 32 ​​is provided on the upper part of the side of the mounting bracket 3. When it passes through the one-way valve 31, it enters the gas-liquid separator 4. When the separation is completed, it is discharged from the outlet 32 ​​and flows into the compressor.

[0016] Specifically, a refrigeration unit 6 is provided on the side of the flow channel plate 2, and a flow channel plate 5 is provided on the upper part of the side of the refrigeration unit 6.

In HP heating mode, interface 2 91 is connected to the compressor discharge interface, solenoid valve 2 is closed, water-cooled condenser heat exchanger interface 9 is opened, and refrigerant enters water-cooled condenser 7 through water-cooled condenser heat exchanger interface 9. The refrigerant flows out after heat exchange in water-cooled condenser 7. The refrigerator electronic expansion valve is closed, and the air conditioning solenoid valve connected to outlet 2 51 is closed. The refrigerant is throttled and depressurized through oil cooler heat exchanger interface 8 and enters the condenser through interface 1 81. After heat exchange in the condenser, it enters the flow channel cavity 21 in flow channel plate 2 through inlet 11 and then enters the mounting bracket 3. The refrigerator electronic expansion valve 1 is closed. The refrigerant flows through solenoid valve 1, through the flow channel cavity 21 in flow channel plate 2, into the guide cavity 35, and then through check valve 31 to enter the gas-liquid separator 4.

In AC cooling mode, interface 2 91 is connected to the compressor discharge interface, solenoid valve 2 is open, water-cooled condenser heat exchanger interface 9 is closed, and refrigerant enters the condenser through inlet 11 via solenoid valve 2. The refrigerant flows out from the condenser heat exchanger and flows into the integrated module through interface 1 81.

Outlet 51 flows to the air conditioning solenoid valve, and after heat exchange in the evaporator, it flows into the mounting bracket 3 through inlet 2 33, flows through check valve 31, enters the gas-liquid separator 4, and flows out from the gas-liquid separator 4 through outlet 32 ​​to the compressor. This process forms a complete circuit.
