摘要：A two-phase liquid cooling system for an electronic component comprised offlexible sealed bag which is partially filled with a liquid coolant. Sufficient residual non-condensing gas is maintained in the bag so that some of the gas dissolves in the liquidcoolant when the device is not operating and at ambient temperature. During warmup,the residual gas comes out of solution and creates nucleation sites that assist in initiatingboiling. The bag is air and fluid-impermeable, and has sufficient flexibility such that ascoolant vaporizes, the bag expands to maintain the internal bag pressure substantiallythe same as the ambient environmental pressure. The bag may also be provided with ametal heat spreader plate which passes through a wall of the bag an assists withtransferring heat from the component to the coolant. The heat spreader plate may bespecially treated to allow the flexible bag material to by directly heat sealed to the plateand to provide nucleation sites to enhance coolant boiling.
