Title:
EBULLIENT COOLING SYSTEM
Document Type and Number:
Japanese Patent JP2015229975
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress refrigerant in a refrigerant passage from intensely boiling.SOLUTION: The present invention provides an ebullient cooling system comprising: an internal combustion engine 10 cooled by boiling refrigerant flowing in a refrigerant passage 12; a gas-liquid separator 14 disposed between the internal combustion engine 10 and an expansion unit 18 and separating the refrigerant from the internal combustion engine 10 into liquid-phase refrigerant and a gas-phase refrigerant; a condenser 24 disposed downstream of the expansion unit 18, and cooling the gas-phase refrigerant passing through the expansion unit 18 to be transformed into the liquid-phase refrigerant; a first passage 28 supplying the liquid-phase refrigerant from the condenser 24 to the refrigerant passage 12; a second passage 30 branched off from the first passage 28 and connected to the gas-liquid separator 14; a control valve 40 controlling a supplied state of the liquid-phase refrigerant supplied from the condenser 24 to the gas-liquid separator 14 via the second passage 30; a temperature sensor 44 acquiring a temperature value of the refrigerant in the refrigerant passage 12; a pressure sensor 46 acquiring a pressure value in the gas-liquid separator 14; and an ECU 48 controlling the control valve 40 on the basis of the temperature value acquired by the temperature sensor 44 and the pressure value acquired by the pressure sensor 46.
