Device temperature regulator

A device temperature regulator capable of regulating a temperature of at least one temperature regulation target device, the device temperature regulator comprising:

• a device heat exchanger configured to function as an evaporator in which a liquid working fluid is evaporated by absorbing heat from the temperature regulation target device at the time of cooling the temperature regulation target device, and to function as a heat radiator in which a gaseous working fluid is condensed to radiate heat to the temperature regulation target device at the time of warming up the temperature regulation target device;
• a condenser that is disposed above the device heat exchanger to condense a gaseous working fluid evaporated in the device heat exchanger at the time of cooling the temperature regulation target device;
• a gas passage part configured to guide the gaseous working fluid evaporated in the device heat exchanger to the condenser;
• a liquid passage part configured to guide the liquid working fluid condensed in the condenser to the device heat exchanger;
• at least one heater configured to heat the working fluid in a device fluid circuit that is configured to include the device heat exchanger, the condenser, the gas passage part, and the liquid passage part;
• and
• a liquid amount regulator configured to regulate a liquid amount of the working fluid collecting in the device heat exchanger, wherein
• the device heat exchanger is configured to include a heat exchange portion disposed opposite to the temperature regulation target device to exchange heat with the temperature regulation target device, and
• the liquid amount regulator is configured to regulate the liquid amount of the liquid working fluid collecting in the device heat exchanger such that an occupancy rate of the gaseous working fluid inside the heat exchange portion becomes larger at the time of warming up the temperature regulation target device as compared with that at the time of cooling the temperature regulation target device.
