Title:
COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/193989
Kind Code:
A1
Abstract:
Provided is a cooling device which cools an object to be cooled while internally generating heat using an electromagnetic wave, and is capable of efficiently supercooling the object to be cooled. The cooling device is equipped with a freezer for cooling the object to be cooled, an electromagnetic wave radiation unit which emits an electromagnetic wave at the object to be cooled in order to internally heat the object to be cooled, and is capable of varying the frequency of the emitted electromagnetic wave, and a control unit which controls the operation of the freezer and the electromagnetic wave radiation unit, and performs a supercooling operation for cooling the object to be cooled using the freezer while radiating the object to be cooled with the electromagnetic wave. In addition, the control unit determines the supercooling operation frequency, which is the frequency of the electromagnetic wave with which the object to be cooled is irradiated by the electromagnetic wave radiation unit during the supercooling operation, and in order to do so, performs a preliminary operation for controlling the electromagnetic wave radiation unit so as to switch the frequency of the electromagnetic wave emitted by the electromagnetic wave radiation unit, and subject the object to be cooled to radiation by electromagnetic waves of a plurality of frequencies. The control unit controls the electromagnetic wave radiation unit so as to emit an electromagnetic wave during the supercooling operation at the supercooling operation frequency determined during the preliminary operation.
