テナーの冷却装置。In a cold container that keeps the inside of the cold storage chamber 1 cool by supplying carbon dioxide gas cold air generated from dry ice to the heat transfer body 2 stored in the cold storage chamber 1, the heat transfer body 2 is placed on the ceiling of the cold storage chamber 1. The surface is constructed to have a flat sealed space that covers the entire area S, and this is provided in the cold storage room 1 at a predetermined distance 1 from the ceiling surface, and a large number of spaces are provided that communicate the upper and lower surfaces of the heat transfer body 2. A through hole 2a is provided to communicate the sealed space of the heat transfer body 2 with the dry ice storage chamber 3 and the collection box 5 equipped with the excess gas release control device 4, so that the heat transfer body 2 is sealed. A fan 6 for forcibly circulating the carbon dioxide gas cold air across the space, the dry ice storage chamber 3 and the collection box 5 is provided, and the fan 6
A cooling device for a dry ice-type cold storage container, which includes a temperature switch 15 that closes when the temperature of a cold storage chamber 1 is higher than a certain temperature in a motor drive circuit.
