Fin evaporator applied to refrigerator, manufacturing method and refrigerator with fin evaporator

Abstract

The invention discloses a fin evaporator applied to a refrigerator, a manufacturing method and the refrigerator with the fin evaporator. The fin evaporator applied to the refrigerator comprises a plurality of evaporating pipes, multiple groups of fins and multiple U-shaped connecting pipes, wherein the evaporating pipes are respectively U-shaped and mutually and vertically arranged at intervals; the fins are horizontally arranged side by side, the evaporating pipes penetrate the fins sequentially, each group of fins comprise a plurality of sub-fins arranged side by side, and the lengths of every two adjacent sub-fins are unequal; and the evaporating pipes are sequentially connected through the connecting pipes. According to the fin evaporator provided by the invention, as the plurality of U-shaped evaporating pipes are adopted and penetrate the multiple groups of the fins, the matching of the fins and pipelines of the U-shaped evaporating pipes are more tight, so that the heat exchange effect of the fin evaporator is improved; and as the sub-fins in different lengths are arranged, the heat exchange superficial area of the fin evaporator is increased, so that the heat exchange efficiency of the fin evaporator is effectively improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a finned evaporator for a refrigerator, a manufacturing method and a refrigerator having the same. Background technique [0002] The evaporator of the traditional air-cooled frost-free refrigerator usually adopts oblique row evaporator or straight row evaporator. The contact between the fins and the evaporating tubes in the two evaporators is not close enough, resulting in low heat transfer efficiency and poor heat transfer effect, which in turn results in a slow cooling speed of the refrigerator, poor cooling capacity and energy consumption. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a finned evaporator for a refrigerator with good heat exchange effect and energy saving. [0004] Another object of the present inventio...
