<p>The present invention relates to a defrosting device for a cold storage type low temperature storehouse, capable of easily and constantly defrosting frost generated on an air circulation heat exchange plate inside a cold storage tank storing a low temperature latent heat phase change material (PCM), installed in all inner sides of a refrigerated or frozen cargo box, to be discharged to the outside. The present invention comprises: an air circulation heat exchange plate formed as a rectangular shape in the center of the cold storage tank to allow an air inlet and an air outlet to be connected; and a defrosting bush forming a supporting unit on the ceiling of the cargo box in an upper end of the cold storage tank by a bracket to remove the frost generated on the air circulation heat exchange plate, vertically installed inside the air circulation heat exchange plate. As a rotational motor is operated when defrosting, the brush connected to a motor shaft rotates along with the rotation of the motor shaft, rakes out an outer cover of the air circulation heat exchange plate whereon the frost is generated, and consistently removes the frost by being moved to the opposite direction by a weight and repeating left and right movement.</p> |
