Embodiment

[0018] An evaporator as shown in the figure, its specific manufacturing process includes the following steps:

[0019] The first step is to design the structure of the aluminum plate 1 according to the heat transfer requirements of the refrigerator and the display cabinet and the product installation size, and design the specific distribution of the aluminum tubes on the aluminum plate 1 according to the diameter of the aluminum tube 2;

[0020] In the second step, the aluminum tube 2 is bent into a snake-shaped aluminum tube formed by several curved arc tubes and straight tubes;

[0021] The third step is to press the snake-shaped aluminum tube into a flat aluminum tube, and use a press to press it into a flat aluminum tube. In this embodiment, the diameter of the snake-shaped aluminum tube is 8mm. 2mm, so that the flat aluminum tube has enough contact area with the aluminum plate 1;

[0022] The fourth step is to coat the brazing flux on the pressed flat aluminum tube, pres...

Abstract

The invention discloses a manufacturing process of an evaporator. The manufacturing process of the evaporator comprises the steps of 1, designing an aluminum plate structure, the diameter of aluminum pipes, and the distribution of the aluminum pipes on the aluminum plate according to the requirement on heat exchange capacity of a refrigerator and a display cabinet and the product mounting dimension; 2, bending the aluminum pipes into a snake-shaped aluminum pipe composed of a plurality of bent arc-shaped pipes and straight pipes; 3, pressing the snake-shaped aluminum pipe into a flat aluminum pipe; 4, coating soldering flux on the flat aluminum pipe, clamping and fixing the flat aluminum pipe and the aluminum plate through a clamp, and then soldering through a controllable atmosphere soldering furnace; 5, releasing the clamp after welding, and respectively welding and fixing an inlet pipe and an outlet pipe at the inlet end and the outlet end of the flat aluminum pipe; 6, spraying powder. According to the manufacturing process of the evaporator, the process is simplified, the production efficiency is increased, the product yield is high, the cost is low, and mass production can be carried out.

Description

Technical field: [0001] The invention relates to a processing technology of an evaporator, in particular to a manufacturing process of an evaporator. Background technique: [0002] At present, inflatable evaporators are generally used in refrigerators, display cabinets, wine cabinets, etc. cold storage rooms. The inflatable evaporator is formed by annealing the aluminum plate, roller brushing, cladding, hot rolling and other steps to form a composite plate. Inflated evaporators are manufactured by way of expansion. The manufacturing process of this evaporator is complex, the production efficiency is low, the reject rate is high, and the production cost is relatively high. Invention content: [0003] The technical problem to be solved by the present invention is to provide an evaporator manufacturing process with simple process and high production efficiency, and the evaporator manufactured by the manufacturing process has high heat exchange efficiency. [0004] The techn...
