Claims

[Scope of utility model registration request]

A cooling device that circulates liquid refrigerant at a predetermined pressure, flow rate, and temperature to the cooled housing and has the required cooling capacity has a bypass from the refrigerant supply pipe to the refrigerant return pipe, and An electric valve installed in the bypass to automatically and gently open the bypass just before the refrigerant circulation stops, and a relief valve installed in the bypass to adjust the pressure remaining in the piping on the side of the cooled housing after the bypass is opened. and a cooling device characterized by having an electric valve installed in the refrigerant supply and recovery passages, which automatically and gently closes the refrigerant supply and recovery passages immediately before the refrigerant circulation is stopped.
