<p>The present invention relates to a defrosting device of a heat exchanger for a cooler which can remove frost by detecting that space between a vaporizer and a blower fan becomes a vacuum state by which outside air is not introduced to an area between the vaporizer and the blower even if the blower fan (250) is operated when frost is accumulated on a surface of a cooling tube (220) and a cooling fin (230) of the vaporizer. According to the present invention, the heat exchanger comprises: a penetrating hole (3) which penetrates a wall surface of a box (50); a connecting pipe (4) communicated with the penetrating hole (3); and a body (5) connected to the connecting pipe (4). The body (5) includes an elastic member (6) accommodated inside the body (5), having elastic properties and a lever (7) which makes power on or off by moving as the elastic member (6) moves.</p> |
