An overall efficient heat dissipation system for a high power density cabinet comprises a pump-driven two-phase circulation loop high-power-chip direct heat dissipation system and a cabinet air-cooling system. The cabinet air-cooling system comprises a refrigerant circulation loop and a cabinet internal air circulation loop. The refrigerant circulation loop includes a pump-driven two-phase circulation loop and a vapor compression circulation loop. The pump-driven two-phase circulation loop high-power-chip direct heat dissipation system performs fixed-point heat dissipation for main heating elements, such as CPU and GPU, in a server, and the cabinet air-cooling system performs air-cooling heat dissipation for other heating elements in the server.

Disclosed is an aircraft environmental control and fuel tank inerting coupling system based on a membrane separation method. The dehumidification of gas in an aircraft environmental control system and the separation of oxygen and nitrogen in a fuel tank inerting system are realized respectively, based on the selective permeability of a membrane to water vapour/air and oxygen/nitrogen. In the coupling system, part of drying gas passing through a membrane dehumidification heat exchanger () enters a membrane air separator (), and the other part thereof is cooled through a large expansion turbine () and then directed into a cockpit for refrigeration; and nitrogen-rich gas generated by the membrane air separator () is directed into a fuel tank for inerting. Oxygen-rich gas is mixed with gas supplied by the environmental control system, thus increasing the oxygen content of gas supplied by the aircraft cockpit.
