Abstract

PURPOSE:To enable the cooling operation to be carried out for a long period of time by providing a group of independent fins arranged dividedly in every row of two or more rows on the windward side of the air flow to the fins and providing a group of integral fins having a fin length which is two or more times longer than that of the independent fins. CONSTITUTION:A refrigerant tube 3 penetrates through independent fins 8, integral fins 9 and end members 2 of a cooler 4, and all of the fins are arranged substantially in parallel in the wind direction. During the cooling operation, the independent fins 8 disposed on the windward side have a high coefficient of heat transfer with respect to an air current a, and the cooler performs, as a whole, the highly efficient heat exchange. However, with the lapse of time, frosting develops from the front edge portions of the fins on the windward side in the direction of the air current A. Thereupon, an electric current flows to a radiant heater 5 for defrosting, and as a result, defrosting is carried out by means of both radiant heat from said heater 5 and heat transfer through the fins, thus attaining a non-frosting state after carrying the current for a predetermined period of time. Accordingly, the air side heat transfer coefficient is thus ensured. Further, in the defrosting operation, the heat transfer efficiency of the integral fins on the leeward side is enhanced to reduce the defrosting time, and consequently the cooling operation for a long period of time can be effected.
