HEAT TRANSFER DEVICE, IN PARTICULAR FOR INTEGRATED CIRCUITS

摘要

A closed two phase liquid-vapor heat transfer device is provided which is independent of orientation and requires no wick. A micro bellows containment vessel is filled with liquid to form a coolant vapor phase bubble which is centered within the vessel due to the surface energy characteristics of the fluid. Heat input at the evaporator section results in evaporation of the liquid at the liquid-vapor interface. The vapor flows across the bubble and condenses on the opposite side where heat is rejected and liquid is replenished to the evaporator section by flow through the continuous liquid film.
