Embodiment Construction

[0074] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a vertical side view of refrigerator R to which the present invention is applied. The refrigerator R in this embodiment is, for example, a commercial refrigerator installed in a kitchen of a restaurant, and its main body is constituted by a heat-insulating box 1 opened on the front surface. The heat insulation box 1 includes: an outer box 2 made of steel plates such as stainless steel and an inner box 3 loaded into the outer box 2; polyurethane heat insulation filled by on-site foaming between the inner and outer boxes 2 and 3 Material 4. In addition, the heat-insulating box 1 (inner box 3 ) constitutes a storage room 5 , and the front opening 22 of the storage room 5 is closed by two sets of doors 6 that can be opened and closed freely. In addition, 7 is a shelf erected in the storage room.

Abstract

The invention provides a refrigerator which effectively discharges waste heat generated by heating elements on a circuit board arranged in a distribution box to achieve balance control. The refrigerator (R) is composed by a cooling device (10) comprising a compressor (18), a condenser (19), and a blower (20) for the condenser, the cooling device (10) being installed in a mechanical chamber (17). The refrigerator (R) comprises a distribution box (28) arranged in the mechanical chamber (17) and accommodating the circuit board (60) for controlling the cooling device (10), and radiating fins (63) facing outside the distribution box (28) and configured to be heat conductive with the heating elements on the circuit board (60).

Description

technical field [0001] The present invention relates to a refrigerator in which a compressor constituting a cooling device, a condenser, a blower for the condenser, and a distribution box containing a circuit board for controlling the cooling device are installed in a machine room. Background technique [0002] Conventionally, commercial refrigerators, freezers, and other refrigerators are installed in restaurant kitchens or supermarket stores, etc., equipped with a cooling device that constitutes a refrigerant circuit by a compressor, a condenser, a decompression device, and a cooler. Cooled air that has exchanged heat with the cooler is circulated in the storage room to cool and store foods and the like at a set temperature. [0003] Cooling devices such as compressors, condensers, and condenser blowers are installed in the machine room outside the storage room. In addition, the machine room is equipped with a distribution box that houses the circuit board that controls th...
