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 coolant and receives heat from a heat generation body which is to be cooled; a heat radiator which radiates the heat of a coolant vapor of the coolant gasified by receiving heat by means of the heat receiver, and recirculates a liquefied liquid coolant to the heat receiver; a valve for controlling the flow rate of the liquid coolant; 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.

Abstract: A temperature control device comprises: first control means; and second control means. The first control means includes first cooling means for cooling of a heat carrier that moves heat from a heat source, and first adjustment means for adjusting a first cooling power being an amount of heat per time to be exchanged in the first cooling means. The second control means includes second cooling means for cooling of the heat carrier, and second adjustment means for adjusting a second cooling power being an amount of heat per time to be exchanged in the second cooling means. The second control means can compensate for a decrease in the first cooling power by a rise in the second cooling power, and can compensate for a decrease in the second cooling power by a rise in the first cooling power.
