Title:
PHASE CHANGE COOLING DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/065352
Kind Code:
A1
Abstract:
Provided are a phase change cooling device and a control method, whereby stable high-efficiency cooling performance can be obtained according to heat exchange performance. This phase change cooling device includes: a heat receiver which accommodates a refrigerant and receives heat from a heat generation body which is to be cooled; a heat radiator which radiates the heat of a refrigerant vapor of the refrigerant gasified by receiving heat by means of the heat receiver, and recirculates a liquefied liquid refrigerant to the heat receiver; a valve for controlling the flow rate of the liquid refrigerant; and a control means for controlling the opening degree of the valve, wherein the control means controls the opening degree of the valve on the basis of an exhaust temperature, which is the temperature after being discharged from the heat receiver, and the temperature in the vicinity of the heat radiator.
