Ice maker ice tray evaporator production technology

Abstract

The invention relates to the technical field of ice making equipment, in particular to an ice maker ice tray evaporator production technology. The method comprises the following steps of 1, copper pipe bending, specifically, a copper pipe is bent through a bending machine according to a drawing and then finished through a punching fixture; and 2, aluminum alloy die casting mold opening, researching, developing and designing, specifically, a corresponding aluminum alloy die casting mold is manufactured, clamping buckles used for controlling the hollow copper pipe to move up and down and move left and right when aluminum alloy die casting is conducted are designed in a front mold body of the mold, and then the copper pipe is directly fixed to the aluminum alloy die casting mold for die casting production. According to the ice maker ice tray evaporator production technology, the copper pipe on the back of an ice maker evaporator is directly die-cast into an aluminum alloy through the aluminum alloy mold and then welded to an ice maker compressor, the copper pipe can achieve refrigerating and heat transferring together with the aluminum alloy absolutely, insulating paint is sprayed tothe back face of the evaporator to prevent energy of the back of the evaporator from being wasted, therefore, the time of making ice cubes by an ice maker is shortened by 30%, and electricity is saved.

Description

technical field [0001] The invention relates to the technical field of ice making equipment, in particular to a production process of an ice tray evaporator of an ice making machine. Background technique [0002] The ice machine evaporator is a utensil installed in the ice machine for making ice cubes. Before the invention, the evaporator had the following problems in production and customer use: [0003] 1. Copper sheet and copper plate are easily deformed due to the properties of copper during punching, which causes each ice cube to be easily deformed. As long as the ice cube is deformed, it is not easy to de-ice, resulting in longer de-icing time. [0004] 2. The copper sheet forms a well-shaped copper grid, the bottom is coated with solder paste, and then assembled with the stamped copper plate. The solder paste is melted into tin water through the high temperature of the oven, and then cooled to connect the copper grid and the copper plate, because the copper cannot be ...

AI Technical Summary

Problems solved by technology

[0003] 1. Copper sheets and copper sheets are easily deformed due to the properties of copper during punching, which causes each ice cube to be easily deformed. As long as the ice cubes are deformed, it is not easy to de-ice, resulting in longer de-icing time

[0004] 2. The copper sheet forms a well-shaped copper grid, the bottom is coated with solder paste, and then assembled with the stamped copper plate. The solder paste is melted into tin water through the high temperature of the oven, and then cooled to connect the copper grid and the copper plate, because the copper cannot be detected. The welding density and strength of each grid and copper plate are very good on the surface. When customers use it, they often find that the copper grid and copper plate fall off after continuous ice making and deicing. This is the market Quality accidents that are completely unacceptable to customers

[0005] 3. The copper tube and the copper plate on the back of the ice machine evaporator are connected together by solder paste welding in the above method. The welding area of ​​the copper tube and the copper plate is only one tenth of the area of ​​the copper tube. The ice machine compressor is welded to the copper plate through the copper tube. Point cooling and heat transfer, the area of ​​the copper tubes and copper plates that are not welded will dissipate energy through the air, resulting in a waste of energy, resulting in longer unit time for ice making and affecting the efficiency of ice making
