Evaporator and refrigerating device

Abstract

The invention provides an evaporator and a refrigerating device. The evaporator is applied to the refrigerating device and comprises a shell and an evaporation tube. The evaporation tube contains a refrigerant. The evaporator is located in the shell and makes contact with the inner wall of the shell. The refrigerant is evaporated and absorbs heat in the evaporation tube. A filling piece is arranged in the evaporation tube and makes contact with the inner wall of the evaporation tube. The filling piece extends in the length direction of the evaporation tube. The cross section area of the filling piece is smaller than the cross section area of the evaporation tube. According to the evaporator, the filling is arranged in the evaporation tube, and the cross section area of the filling piece is smaller than that of the evaporation tube; in this way, the heat exchange area of the refrigerant is increased, the heat exchange efficiency is improved and the refrigerating speed is higher; the filling amount of the refrigerant is reduced under the same refrigerating effect, the efficiency of the refrigerant in a pipeline is improved, and the refrigeration efficiency of the whole machine is improved; the filling piece can be used as a cold storage agent to participate in the whole refrigeration cycle, the refrigerating capacity is improved, and the energy consumption of the whole machine is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an evaporator and a refrigeration device. Background technique [0002] Existing evaporation pipeline structure such as figure 1 and figure 2 There are two types shown, one is to directly use the circular evaporation tube 4' to contact the inner wall of the evaporator shell 2' for heat exchange, and the other is to use the D-type technology to flatten the side of the evaporation tube 4'. The contact effect with the inner wall of the shell 2' is improved, but both technologies do not perform enhanced heat transfer treatment on the inner wall of the evaporation pipeline. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] To this end, an object of the invention is to propose an evaporator. [0005] Another object of the present invention is to propose a refriger...
