置。[Claims for Utility Model Registration] (1) In a cooling device that can switch the airflow rate of the fan to the condenser in at least two stages, an energization path is provided that turns on when the cooling device is started and increases the airflow rate of the fan to the condenser. 1. A cooling device comprising: a large air volume control circuit that forms a large air volume control circuit and maintains an on state until a cooling temperature falls to a predetermined value. (2) The large air volume control circuit includes a time limit switch that is turned on for a predetermined time when the start switch is turned on, and an air volume switch that is self-maintained by the time switch and forms an energization path that increases the air volume of the fan to the condenser. and temperature switch means for turning off the air volume switch means when the cooling temperature falls to a predetermined value.
