Abstract: With a phase change cooling device, it is difficult to obtain reliable high-efficiency cooling performance due to a change in heat exchange performance. Thus, a phase change cooling device according to the present invention includes: a heat receiving apparatus that houses a coolant; a sensor that acquires heat receiving apparatus coolant information that is information relating to a liquid-gas two-phase flow interface of the coolant housed in the heat receiving apparatus; a radiator that radiates heat of coolant vapor of the coolant heat-received and evaporated in the heat receiving apparatus, and recirculates liquefied coolant liquid to the heat receiving apparatus; a valve that controls a flow rate of the coolant liquid; and a control unit that controls a degree of opening of the valve, wherein the control unit controls, based on the heat receiving apparatus coolant information, a degree of opening of the valve in such a way that a liquid-gas two-phase flow interface of the coolant is located at an end part of the heat receiving apparatus in a vertical direction.
