。[Scope of Claim for Utility Model Registration] An engine water jacket in which a refrigerant made of antifreeze is stored in a liquefied state, a condenser that condenses the vapor refrigerant vaporized by heat absorption from the engine in the water jacket with outside air, and the condenser. A liquefied refrigerant passage for circulating liquefied refrigerant back to the water jacket, and a liquefied refrigerant passage for circulating the liquefied refrigerant to the water jacket. A refrigerant supply pipe is provided to supply the jacket.
Further, pressure sensors are provided in the liquefied refrigerant passage at different positions with respect to the flow direction of the refrigerant, and a pressure signal from the pressure sensor is input, and if the refrigerant concentration calculated based on the pressure loss is below a predetermined value. For example, an engine boiling cooling device comprising a control means for outputting a control signal for operating the pump.
