Description

Technical Field

[0001] This utility model relates to the field of automotive valve technology, and in particular to a multi-way valve for thermal management of new energy vehicles. Background Technology

[0002] The importance and complexity of thermal management systems in new energy vehicles are gradually increasing, especially the complexity of water circuits. Miniaturization and integration of thermal management systems have become industry trends. The performance of vehicle energy consumption and driving range is also receiving increasing attention. Heat pump systems are gradually becoming more widespread, and system modes are becoming more and more diverse. The current system modes mainly include: passenger compartment heating and battery pack cooling; passenger compartment heat pump heating alone; passenger compartment and battery cooling simultaneously; passenger compartment and battery pack heating simultaneously; motor heating battery pack; passenger compartment and battery heating; passenger compartment heat pump heating; passenger compartment heating and battery cooling. When implementing the above functions, existing thermal management systems require an additional flow channel and a corresponding valve to control that flow channel for each additional function. Therefore, thermal management systems usually have multiple valves, resulting in low integration. Improvements are needed to design a highly integrated valve body that is easy to install and connect to pipelines. Utility Model Content

[0003] The purpose of this invention is to provide a multi-way valve for thermal management of new energy vehicles to solve the problems mentioned in the background art.

Specifically, a support groove 9 is provided at the top of the annular bottom groove 8. The inner side of the adjusting ring 6 slides inside the support groove 9. A limit screw is provided at the middle position of the adjusting ring 6. When the adjusting ring 6 is adjusted to the correct position, the limit screw can be rotated to achieve positioning.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this utility model discloses a multi-way valve for thermal management of new energy vehicles. Specifically, a top plate 1 is provided on the top of the valve seat 5, a dust cover 2 is movably provided on the top of the top plate 1, a support rod 13 is provided at the center of the top of the valve core 14, a locking screw 15 is provided on the top of the support rod 13, and the top of the locking screw 15 passes through the dust cover 2 and is sleeved with the locking nut 4 on the top of the dust cover 2.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a multi-port valve for thermal management of new energy vehicles. Specifically, the top of the dust cover 2 is provided with an inlet pipe 3, and the top of the valve core 14 is provided with a socket 17 that communicates with the liquid guide port 20. The bottom end of the inlet pipe 3 is inserted into the socket 17. The bottom of the inlet pipe 3 is equipped with a rubber sealing block. When the bottom end of the inlet pipe 3 is inserted into the socket 17, the rubber sealing block is also pressed against the top port of the socket 17 to achieve a seal.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a multi-way valve for thermal management of new energy vehicles. Specifically, a drive motor 11 is provided on the top side of the top plate 1, and a drive gear 12 is connected to the output end of the drive motor 11. A side groove 22 is provided on the side of the top plate 1, and the drive gear 12 is placed inside the side groove 22.

[0028] The working principle of this utility model is as follows: When the valve seat 5 of this application is in use, the external coolant and heating liquid enter the valve core 14 through the inlet pipe 3. The liquid flows out from the liquid guide port 20 inside the isolation chamber 19 after passing through the inlet pipe 3 and the inlet 17 in sequence. When the isolation chamber 19 is rotated to one of the liquid guide ports 23, the liquid can flow from the isolation chamber 19 into the liquid guide port 23. Impurities can be intercepted by the dust screen 18. The liquid that enters the liquid guide port 23 flows again into the liquid guide hose 10 and is discharged through the outlet pipe 7 outside the adjusting ring 6. When adjusting the flow direction of the internal pipeline, the toothed plate collar 16 can be rotated by the drive gear 12, and the valve core 14, which is sleeved with the toothed plate collar 16, rotates. This causes the isolation chamber 19 at the bottom of the valve core 14 to adjust its position to correspond to the liquid guide port 23 at other positions. In this way, the pipeline switching connection can be realized.
