ABSTRACT:
A cooling apparatus for use in a cooling system. The cooling apparatus has many evaporators disposed transversely to a longitudinal direction of a cool air duct. The refrigerant is supplied respectively to the evaporators by a valve device. Each evaporator has a conductive pipe which is wound spirally. Many blowers are disposed to each of the evaporators respectively. The diameter of wound part of the conductive pipe increases gradually along the circulating direction of the cool air, so the evaporators substantially have cone-shapes. Many defrosting heaters are disposed coaxially with the conductive pipes respectively. Since the evaporators are controlled respectively, at least one evaporator is operated during the defrosting operation of other evaporators, so the cooling efficiency is increased. Also, the heat exchange is performed uniformly on the entire areas of the evaporators by the spirally wound conductive pipes, the cooling apparatus has high efficiency of cooling.
