Abstract
An integrated refrigerator evaporator having a plurality of pipes and fins is manufactured by injection molding with plastics. According to the present invention, pipes and fins are molded by plastic plates, and a heat exchanger is formed by molding the pipes and fins into a series of “S” shapes. A first bending section formed by the heat exchanger, which is molded in a series of “S” shapes, is inserted into a mold main body to manufacture a header cap. A first header cap is manufactured by injected melted plastic material body into the mold main body under the state of covering the mold main body with a mold cap. The first header cap is engaged with a first header main body having a refrigerant inlet and outlet. The refrigerator evaporator according to the present invention results in a relatively lower product cost than the evaporator composed of a metal substance, as well as a high recyclability.
