Abstract
An apparatus for cooling semiconductor devices includes a module for cooling semiconductor devices; a refrigerant cooling device for receiving via an outlet pipe the refrigerant discharged through an outlet port of the module to cool the refrigerant; a refrigerant circulation pump for receiving, via a suction pipe, the refrigerant cooled by the refrigerant cooling device and sending the refrigerant to the module via an inlet pipe; and a refrigerant-flow stabilizing mechanism for stabilizing a refrigerant circulation flow discharged from the refrigerant circulation pump to be returned to the refrigerant circulation pump via the module and the refrigerant cooling device. Since the refrigerant-flow stabilizing mechanism stabilize the refrigerant flow, the refrigerant flow can be stably circulated so that the semiconductor devices in the module are stably cooled.
