Although the heat radiating pipe 18 is arranged on the front plate 22 coated with the heat sink 3, the heat insulating paint 23 may be applied after the heat radiating pipe 18 is arranged. By disposing the heat radiating pipe 18 directly on the front plate 24, the amount of heat from the heat radiating pipe 18 can be directly transmitted to the front plate 22, so that the heat radiating ability is improved. Moreover, if the heat-insulating paint 23 is applied to the partition body side of the front plate 22 so as to cover the surface of the heat radiating pipe 18, the heat intrusion into the refrigerator is further suppressed, and the cooling system efficiency is improved.
