Refrigerating evaporator with auxiliary refrigeration evaporator

Abstract

The invention discloses a refrigerating evaporator with an auxiliary refrigeration evaporator. The refrigerating evaporator comprises a first evaporator and a second evaporator, wherein the first evaporator is a plate tube structure, and comprises a first aluminum plate and an evaporating tube which is fixedly arranged on the first aluminum plate after being bent in a multi-round way, and the second evaporator is arranged below the first evaporator and consists of an evaporating tube arranged below the first evaporator and a second aluminum plate, thereby forming the evaporator for auxiliary refrigeration of a refrigerator. Further improvement is as follows: the evaporating tube is bent into a coil structure that the adjacent evaporating tubes are arranged in parallel and are fixedly connected onto the second aluminum plate, and the end parts of the adjacent evaporating tubes arranged in parallel are connected in a 9-shaped curve shape; the first evaporator and the second evaporator are vertically arranged. The refrigerating evaporator provided by the invention has the advantages that the cooling effect of a freezer can be significantly improved, and the energy consumption is reduced; the refrigeration capacity of the refrigerating evaporator is fully utilized, and the waste is avoided; the sealing performance is good, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to an evaporator, in particular to a refrigeration evaporator for a refrigerator. Background technique [0002] The refrigerating evaporator and freezing evaporator of the existing refrigerator are basically independent of each other, and are respectively responsible for the refrigeration of the refrigerator's refrigerating chamber and freezing chamber. In the case of insufficient cooling capacity of the refrigerating evaporator, the refrigerating capacity of the refrigerating evaporator of the refrigerator is not fully utilized. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a refrigeration evaporator with an auxiliary refrigeration function. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The refrigerating evaporator provided with an auxiliary refrigeration evaporator includes a first evaporator; the fi...
