Dual-phase flow cooling plate testing system

Abstract

A two-phase flow cooling plate testing system includes a heating device, a refrigerant storage device, a main circulation device, and a first recovery device. The refrigerant storage device includes a storage container and a condenser for cooling the refrigerant, which is in a gaseous phase within the storage container, into a liquid phase. The main circulation device includes two connection ends connecting to a cooling plate assembly, a circulation path communicating with the connection ends, a heat exchange module, two first connection valves, two second connection valves, and a circulation pump. The circulation path has a recovery section located between one of the first connection valves and an adjacent second connection valve. The first recovery device includes a first recovery path communicating with the storage container and the recovery section, and a first recovery valve. The refrigerant can be automatically recovered through the pressure difference caused by the condenser condensing the refrigerant.
