Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to an evaporator applied to a cold dryer. Background Art

[0002] The evaporator is a very important part of the four major parts of refrigeration. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, gasify and absorb heat, and achieve the effect of refrigeration. When assembling the dryer, the evaporator is one of the essential parts of the dryer and is its main heat exchange component. The compressed air is forced to cool in the evaporator, and most of the water vapor is cooled and condensed into liquid water and discharged outside the machine, so that the compressed air is dried. The low-pressure refrigerant liquid undergoes a phase change in the evaporator and becomes a low-pressure refrigerant vapor. During the phase change process, it absorbs the surrounding heat, thereby cooling the compressed air.

[0003] Prior art includes a utility model with publication number CN208975180U, which discloses an evaporator used in a cold dryer. The patent adopts a shell and an input pipe, the input pipe is arranged through the upper end of the shell, and the internal pipe of the input pipe is in a V-shaped structure. An evaporation pipe is arranged inside the shell, and the evaporation pipe is composed of at least two S-shaped pipes, and the head end of the evaporation pipe is extended to the left end of the shell, and the tail end of the evaporation pipe is extended to the right end of the shell. At least two water receiving pipes communicating with the left and right ends of the shell are provided through the left and right ends, and the lower sides of the left and right ends of the inner wall of the shell are inclined downward by twenty to forty degrees. An inclined plate is fixed at the corner; it is suitable for production and application in the field of evaporator technology. The evaporator used in the cold dryer pours nano negative ion powder into the input pipe so that the nano negative ion powder can slowly drip from the input pipe into the powder dripping pipe. Since the powder dripping pipe is a convex structure and the pipe at the lower end of the powder dripping pipe is a V-shaped structure, the nano negative ion powder can be dripped into the evaporation pipe through the powder dripping pipe, which solves the problem that during the use of the existing evaporator, since the evaporation pipe is installed inside, it is inconvenient for the staff to clean the structure of the inner wall, which makes the maintenance operation of the staff cumbersome.

[0004] The inventors have discovered in their daily work that in the process of using an evaporator for cooling, there are existing pipes of the evaporator, such as the above-mentioned one, which only rely on the two ends of the evaporator tube to support itself, so that the load of the pipe is applied to the connection between the pipe and the shell. After the equipment has been working for a long time, the load on the connection is higher than that on other structural parts, causing fatigue in the structure of the connection, resulting in deformation, which can easily lead to serious structural damage to the connection.
