Abstract

The application relates to a high-efficiency phase-change condenser for a supercomputer, including a condenser box body, a refrigerant input pipe, a refrigerant output pipe and a condensing coil; a liquid refrigerant accommodated in the condenser box body, and a gas-phase region existing between a liquid level of the liquid refrigerant and a top of the condenser box body; one portion of the condensing coil immersed into the liquid refrigerant, and the other portion of the condensing coil located in the gas-phase region above the liquid level of the liquid refrigerant; and in the gas-phase region, refrigerant vapor bubbles are liquified by the condensing coil. Liquid-phase and gas-phase saturated refrigerants can be completely condensed by the condensing coil in a limited condenser space, thereby improving heat exchange efficiency of the condenser.
