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.

The present invention relates to a line contact one-way valve, in particular to a line contact one-way valve that fixes a valve plate through a baffle structure with a through hole, which can be applied to a line contact one-way valve of an engine breathing system. Since a through hole structure is provided on the baffle that fixes the valve plate, the suction resistance of the valve plate when it is separated from the baffle when the one-way valve is closed is reduced, thereby improving the stability of the one-way valve. In addition, the smaller contact area of ​​the line contact reduces the adhesion of the oil at the contact point of the valve plate due to viscosity, and the adhesion resistance of the valve plate when opening the one-way valve is smaller. The small movement resistance and small movement stroke of the valve plate enable the one-way valve to quickly switch between opening and closing, thereby making the one-way valve have higher sensitivity.
