<P>PROBLEM TO BE SOLVED: To provide a refrigerating device for a freezer such as a refrigerating container capable of reducing sizes of heat radiating fins of an inverter. <P>SOLUTION: The refrigerating device for the freezer is provided with: an evaporator 16 of a refrigerating cycle cooling the inside of the freezer; an electrically driven compressor 14 composing the refrigerating cycle; an inverter 15 for converting the frequency of supply power into the electrically driven compressor 14; the heat radiating fins 15b for radiating the heat of the inverter 15 into air; and a holding member 11 for covering the opening of a box body 2 composing the freezer, and holding the evaporator 16, the electrically driven compressor 14, and the inverter 15. The holding member 11 provides a ventilation window 20 for ventilating the inside of the freezer, and provides an exhaust duct 21 for guiding air in the freezer of exhaust of the ventilation window 20 to the heat radiating fins 15b. Thereby, since the air in the freezer having a lower temperature than air out of the freezer cools the heat radiating fin, the miniaturization of the heat radiating fins is enabled compared with the case that the air out of the freezer simply cools the heat radiating fins. <P>COPYRIGHT: (C)2012,JPO&INPIT |
