Classification: CPC H  B  F | IPC B  F  H

Claim 0:
1. A cooling device, comprising:
a flow path configured to flow a refrigerant:
a condenser provided in the flow path:
a heat exchanger provided in the flow path:
a compressor provided in the flow path between the condenser and the heat exchanger:
a cooler cooling the refrigerant flowing from the condenser into the heat exchanger:
a gas cooling part supplying a gas to the heat exchanger:
the heat exchanger configured to cool the gas by exchanging heat exchange between the refrigerant and the gas,
a first thermometer configured to detect a temperature of the cooled gas by the gas cooling part:
a second thermometer configured to detect a temperature of the refrigerant flowing into the heat exchanger: and
a first controller configured to control the temperature of the cooled refrigerant by the cooler, the refrigerant flowing into the heat exchanger,
the first controller controlling the temperature of the cooled refrigerant flowing into the heat exchanger by switching a first control and a second control, the first control being based on the temperature detected by the first thermometer, the second control being based on the temperature detected by the second thermometer,
the first controller performs
the first control when a flow rate of the gas supplied to the heat exchanger is equal to a predetermined value or more, and
the second control when a flow rate of the gas supplied to the heat exchanger is less than a predetermined value.
