Abstract

A phase-separated evaporator includes a boiler plate and a phase separation chamber that includes a housing, connected to the boiler plate, having a gas port and a liquid port; and a phase partitioner connected to interiors of the housing, dividing the phase-separated evaporator into a vapor directing compartment and a condensate directing compartment. The phase partitioner includes a partition panel and multiple feeding injectors extending from the partition panel, with the injector tips disposed immediately above the boiler plate. The returning condensate from a condenser enters from the liquid port into the condensate directing compartment and feeds onto the boiler plate through the feeding injectors; while the vapor generated in the vapor directing compartment exits from the gas port, without encountering the condensate. Further disclosed are a high efficiency heat dissipation system utilizing the phase-separated evaporator and a blade-thru condenser, and a computer system utilizing the heat dissipation system.
