Abstract

The present invention provides a freezing / cooling device which is uncomplicated in structure, and can raise safety and efficiently remove frost. Each fan shield heater (4) in a unit cooler (A) comprises a first straight line portion (41) and a straight line portion which is formed in a manner of surrounding a part of the periphery of a central hub portion of a fan (6) of an air blower. The first straight line portion is mounted under a fan shield (2) and straightly extends along the width direction of the fan shield (2).

Description

technical field [0001] This invention relates to the freezing / cooling apparatus which cools the inside of a freezer, a refrigerator, etc., for example. Background technique [0002] Conventionally, for example, there is a freezing / cooling device (hereinafter referred to as a unit cooler) that cools the inside of a freezer, a refrigerator, or the like. Many of these unit coolers have a main body case formed with a suction port and an air outlet, an evaporator provided at a position facing the air outlet of the main body case, and a blower provided in the main body case. The evaporator cools the air by evaporating the refrigerant supplied by the action of the externally mounted compressor. The air blower supplies the air in the cooling target space such as a warehouse to the evaporator, and supplies the air cooled by the evaporator to the cooling target space. In addition, in some unit coolers, the air outlet of the main body box is provided with a fan guard to prevent forei...
