Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and particularly to a flowing water type crescent ice ice maker evaporator. Background Art

[0002] An ice maker is a refrigeration mechanical device that cools water through an evaporator with a refrigerant in a refrigeration system to generate ice. According to different principles of the evaporator and the generation process, the shape of the generated ice is also different. Generally, ice makers are classified into pellet ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc. according to the shape of the ice. Among them, the variety of pellet ice is the most, including square ice, round ice, bullet ice, cup-shaped ice, crescent ice, etc.

[0003] As an important component in an ice maker, the principle of the evaporator is that high-pressure refrigerant liquid evaporates in the evaporation tube through a throttling device, and the gasification absorbs heat to achieve a refrigeration effect. The evaporation tube conducts the cold quantity to the ice template in the ice maker, so that the water poured into the ice template freezes into ice cubes and can be used.

[0004] The flowing water type crescent ice ice maker is a relatively popular ice maker in the market. The evaporator of this ice maker uses double-sided ice making. The evaporator is welded by two stainless steel ice templates and a serpentine evaporation coil. The ice-making water flows through the ice template from top to bottom.

[0005] In the existing ice maker evaporator, the ice template and the evaporation tube are separately arranged. The evaporation tube is coiled and welded to the bottom plate of the evaporator, with a small contact area, low energy transfer efficiency, and low energy efficiency.

[0006] In order to ensure that the evaporation tube can reliably cool the ice template, it is necessary to ensure the tightness between the evaporation tube and the ice template during manufacturing and assembly. In the prior art, the manufacturing process at this place is as follows: first, tin is plated on the surfaces of the ice template and the evaporation tube, then soldering paste is applied between the evaporation tube and the ice template, and then the copper tube and the ice template are clamped with a fixture and placed in a heating furnace for heating. After heating for a certain time at a specified temperature, it is taken out, cooled, and then cleaned with a reagent.

[0007] Adopting this kind of welding and assembly process, although it can ensure the tight connection between the ice template and the evaporation tube, it has the defects of complex process and high process requirements. At the same time, it is difficult to repair and replace the ice tray of this kind of evaporator, with high technical difficulty, high cost, and low flexibility. Summary of the Invention
