This invention provides a high-heat-dissipation battery component for new energy vehicles, belonging to the field of new energy vehicle heat dissipation battery technology. It includes a protective shell, inside which a cooling module is installed. The cooling module is used to cool the entire battery module. The battery module consists of a mounting box and battery cells. The battery cells are installed in mounting slots within the mounting box. A top plate is installed on the top of the battery module. The cooling module is connected to a serpentine cooling pipe, which has several adjusting components. Several adjusting components are arranged between adjacent sections of the serpentine cooling pipe. This invention, through the corresponding combination design of the cooling module, the serpentine cooling pipe and adjusting components, and the serpentine cooling pipe and adjusting components, achieves dual heat dissipation functions: overall cooling of the battery module and precise heat dissipation of individual battery cells, thus improving maintenance convenience.

The application discloses a servo cut-off valve group, which comprises a first valve body and a second valve body integrated on a valve seat. Both the valve bodies are provided with valve cavities, and the valve cavities are internally provided with valve spools driven by a servo motor through a screw rod. The valve bodies are provided with outer ring channels communicated with inlet and outlet of the valve seat on the side surfaces, the outer ring channels are communicated with the valve cavities through a plurality of uniformly distributed lateral flow channels, and the inner walls of the valve cavities are further provided with inner ring channels. The longitudinal flow channels at the bottoms of the two valve cavities are communicated with each other through channels in the valve seat. When the two valve spools synchronously rise above the lateral flow channels, fluid can sequentially pass through the flow channels, and the valve is opened; when the two valve spools synchronously descend to completely cover the lateral flow channels, the valve is closed. The two valve cavities are communicated at the bottoms to form a pressure balance cavity, so that the valve spools are hardly subjected to axial thrust when the valve is closed, and high pressure is converted into sealing force in the radial direction of the valve spools, thereby fundamentally solving the high pressure leakage problem of traditional cut-off valves, and the application is especially suitable for high pressure equipment such as filter presses.

This invention belongs to the field of new energy technology and discloses a main unit of a dual-airflow, dual-refrigeration system with orthogonally arranged air inlet and outlet surfaces. The main unit includes a housing, two sets of refrigerant circulation systems disposed within the housing, and an exhaust chamber. Each set of refrigerant circulation systems has an independent external heat exchanger negative pressure chamber and an exhaust chamber. The external heat exchanger negative pressure chamber consists of an external heat exchanger, part of the housing, and a back plate. Several air outlets for the external heat exchanger negative pressure chamber are provided on the back plate, corresponding to the air inlets of vertically arranged fans. The air outlets connect to the exhaust chamber. The exhaust outlet of the exhaust chamber is located on the side plate of the housing and orthogonally arranged to the air inlet surface of the housing. This invention constructs a low-resistance external heat exchanger airflow path through the louvers of the exterior facade, constructs an external heat exchanger assembly structure, improves the energy density of the main unit, reduces the number of devices, simplifies the spatial structure, and reduces the floor space required.
