3results about How to "Prevent excessive temperature rise" patented technology

The present application provides a thermal management system and a vehicle. The thermal management system is provided with a battery that exchanges heat with a thermal medium of an F4 flow path, a drive axle that exchanges heat with a thermal medium of an F2 flow path, and a switching device. The switching device forms a thermal circuit that connects the F4 flow path and the F2 flow path after the temperature of the thermal medium of the F4 flow path is detected by a flow path sensor and the detected value of the flow path sensor is lower than a threshold value Tb. The switching device forms a thermal circuit that includes the F4 flow path and is isolated from the F2 flow path after the temperature of the thermal medium of the F4 flow path is detected by the flow path sensor and the detected value of the flow path sensor is higher than or equal to the threshold value Tb and lower than a threshold value Tc.

The invention discloses a heat exchange device resistant to high temperature, high pressure and hydrogen corrosion, which comprises a shell and a tube sheet arranged in the shell, the tube sheet divides the inner cavity of the shell into a heat exchange cavity and a refrigerant cavity; the refrigerant cavity is divided into a liquid inlet cavity and a liquid outlet cavity; an insulation tube and a high-temperature inner box are installed in the heat exchange cavity, and the two ends of the U-shaped heat exchange tube are connected to the liquid inlet cavity and the liquid outlet cavity through the tube sheet; a connecting portion connecting the inside and outside of the insulation tube is provided between the insulation tube and the tube sheet; the high-temperature inner box is connected to the insulation tube; a gas inlet pipe and a gas outlet pipe are arranged on the shell, the gas inlet pipe is directly opposite to the high-temperature inner box and connected to the high-temperature inner box, and the gas outlet pipe is directly opposite to the connecting portion; a first thermal insulation material is filled between the high-temperature inner box and the shell, and the annular gap between the insulation tube and the cylinder body forms a dead gas zone, and the dead gas zone is connected to the inner cavity of the insulation tube through the connecting portion. By using the present application, the manufacturing cost of the equipment can be well reduced.
