The direct cooling and direct heating heat pump air conditioning thermal management system is a new blue ocean in the field of new energy vehicles. With the rise of thermal management systems, the number of components has increased. As a key functional component of the system, the thermal management integration module integrates related components and accurately controls the operation of each component through the on-board computer to ensure the safe, orderly and efficient operation of each system, greatly improving the performance and reliability of the vehicle. At the same time, it also saves space and costs, making the front cabin more standardized and beautiful.

[0003] The integrated module of thermal management for new energy vehicles includes an upper shell and a lower shell. The lower shell is die-cast to form a channel, and then the upper shell and the lower shell are welded together through a vacuum welding furnace to form a sealed flow channel for the circulation and distribution of refrigerant. However, the vacuum welding furnace requires large investment, large land area, high energy consumption, and high requirements for technical personnel. All defective products after welding are directly scrapped and cannot be reused. Summary of the invention

[0004] The utility model provides a thermal management integrated module structure for new energy vehicles with simple process, low cost, low requirements for technical personnel, and will not be scrapped as a whole; it solves the technical problems in the prior art that the thermal management integrated module for new energy vehicles has high process requirements, one point is not welded firmly, it is easy to be scrapped as a whole, the cost is high, and the requirements for technical personnel are high.

[0005] The above technical problems of the utility model are solved by the following technical solutions: a thermal management integrated module structure of a new energy vehicle, including an upper shell and a lower shell, a refrigerant channel is provided on the upper shell, an upper sealing groove is opened on the upper shell, the upper sealing groove is parallel to the refrigerant channel, a sealing ring is filled in the upper sealing groove, and the upper shell and the lower shell are connected by a connector. The sealing groove is sealed by a sealing ring, and then positioned and fixed by a connector. The process is simple and easy to operate. There is no need to invest in large welding equipment. If a leak is found in the valve island during assembly, local repair welding can be selected, which solves the problem of directly scrapping all defective products after welding and saves costs.

[0006] Preferably, the upper sealing groove is located on both sides of the refrigerant channel. Sealing grooves are provided on both sides of the refrigerant channel to improve the sealing performance.

[0007] Preferably, a lower sealing groove is provided on the lower shell body, and the upper sealing groove and the lower sealing groove form a sealing space correspondingly, and a sealing ring is installed in the sealing space, so as to facilitate the positioning of the sealing ring and improve the sealing performance.

[0008] Preferably, the cross section of the sealing ring is H-shaped to ensure the effectiveness of the seal.

[0009] Preferably, the connecting member comprises positioning pins and bolts.

[0010] Preferably, the upper sealing groove is 2mm-3.5mm away from the refrigerant channel, the width of the upper sealing groove and the lower sealing groove is 3mm-4mm, and the height of the sealing ring is 5mm-6.5mm, so as to ensure sealing while minimizing the wall thickness and reducing costs.

[0011] Therefore, the thermal management integrated module structure of a new energy vehicle of the utility model has the following advantages:

[0012] 1. Save the one-time large investment in welding equipment;

[0013] 2. Solved the problem of high requirements for personnel for welding equipment;

[0014] 3. If a leak is found in the valve island during assembly, local repair welding can be selected to avoid the problem of having to scrap the entire valve island once a local leak occurs in the vacuum welding method, thus saving costs;

[0015] 4. The H-type sealing ring with good sealing performance is used to adapt to the problem of thermal expansion and contraction caused by the high temperature and high pressure changes of the refrigerant during the operation of the valve island. BRIEF DESCRIPTION OF THE DRAWINGS
