Abstract

An evaporator includes an outer fluid enclosure, a liquid inlet port extending through the outer fluid enclosure, a liquid-distribution structure, a wick, and a vapor removal channel. The liquid-distribution structure is joined to the outer fluid enclosure to form a fluidly sealed hermetic chamber. The liquid-distribution structure includes a vapor barrier wall having an outer heat-receiving surface and the liquid-distribution structure is configured to distribute liquid over an inner surface of the vapor barrier wall. The wick is positioned inside the fluidly sealed hermetic chamber and is coupled to a liquid inlet port. The vapor removal channel is defined by and is in fluid communication with the wick and the liquid-distribution structure, and is near the outer heat-receiving surface of the vapor barrier wall. A thermal conductance of the liquid-distribution structure is higher than a thermal conductance of the wick.
