Aluminum alloy evaporating pipe for freezing device

A freezing device, aluminum alloy technology, applied in household refrigeration devices, evaporators/condensers, applications, etc., can solve the problem that the bottom of the cold plate and the tube plate are difficult to be in close contact, the unfavorable temperature field is evenly distributed, and the freezing process is reduced and reliable. It can reduce the contact thermal resistance, improve the freezing speed, and prevent aggregation.

Problems solved by technology

In practical applications, it is difficult to achieve close contact between the bottom of the cold plate and the flat plate of the tubes, and the contact thermal resistance is large, which reduces the reliability of the freezing process
The heat transfer of the traditional shelf evaporator is divided into heat conduction and air heat exchange, and the low share of heat conduction is an important reason for the low efficiency of this type of evapo

Abstract

The invention discloses an aluminum alloy evaporating pipe for a freezing device. The aluminum alloy evaporating pipe comprises a pipe body molded from an aluminum alloy material, wherein the pipe wall of the pipe body consists of a top wall, a bottom wall and two side walls; the width of the bottom wall is smaller than that of the top wall; the outer surface of the top wall is a smooth plane; a to-be-frozen object is directly placed on the outer surface of the top wall; a first fin structure is arranged on the inner side surface of the top wall; the outer surfaces of the two side walls are both of structures which are protruded towards the interior of the pipe body in the shape of arc. The aluminum alloy evaporating pipe for the freezing device, provided by the invention, has the characteristics of large heat exchange area, high heat exchange efficiency and the like.

Description

technical field [0001] The invention relates to an aluminum alloy evaporation tube for a freezing device. Background technique [0002] With the development of cold chain technology and the promotion of its application, various forms of freezing devices have been introduced. Among them, the shelf-type row-pipe evaporator is mostly used for freezing processed foods in the freezing chamber, and is especially suitable for plate-packed frozen products. Existing shelf-type evaporators, the evaporator tubes are often made of steel pipes or aluminum alloy tubes, etc., and the cold plate (frozen material on the plate) is placed directly on the pipe or placed on the laid flat plate and the upper surface is made of aluminum alloy extruded into the bellows plate. In practical applications, it is difficult to achieve close contact between the bottom of the cold plate and the flat plate of the tubes, and the contact thermal resistance is large, which reduces the reliability of the free...
