Description

Technical Field

[0001] The utility model relates to the technical field of ice trays, and specifically, to a die-cast liquid-cooled ice tray. Background Art

[0002] The existing ice trays are multi-row and multi-column ice grids formed by soldering copper sheets, and the surfaces of the ice grids are nickel-plated to achieve the purpose of anti-corrosion.

[0003] However, the temperature of soldering copper sheets is generally 200°C. When the ice grids are used for ice making for a long time, they repeatedly experience the alternation of cold and heat, and due to the thermal expansion and contraction, they are prone to de-soldering, resulting in the separation of the copper sheets soldered together and the damage of the ice grids.

[0004] In addition, nickel plating on the surface of the ice grids, although having the function of anti-corrosion, cannot solve the problem of scale formation in the ice grids and pollution of ice cubes. In particular, after the ice grids are used for a long time, copper reacts with substances such as oxygen, carbon dioxide, and water vapor in the air to produce copper green, that is, basic copper carbonate, which is a toxic substance and is not conducive to human health.

[0005] Furthermore, the existing ice trays have low ice-making efficiency and high refrigerant consumption, resulting in high ice-making costs.

[0006] Therefore, it is urgent to develop a new ice tray to solve the above problems existing in the prior art. Content of the Utility Model

[0007] In order to overcome the deficiencies of the prior art, the utility model provides a die-cast liquid-cooled ice tray, which overcomes the technical problems in the prior art, such as the copper ice trays made by soldering are prone to fall apart and be damaged, scale is generated to pollute ice cubes, copper green is generated by oxidation during long-term use, and ice-making efficiency.

[0008] The technical solution of the utility model is as follows: A die-cast liquid-cooled ice tray includes a copper tube and an aluminum alloy die-cast to wrap the copper tube. A part of the copper tube is exposed outside the aluminum alloy. A heat-insulating material layer is sprayed on the back of the aluminum alloy. On the front of the aluminum alloy, multi-row and multi-column ice grids are die-cast, and a Teflon coating is sprayed on the front of the aluminum alloy.

[0009] The part of the copper tube wrapped inside the aluminum alloy is bent into multiple parallel columns, so as to increase the length of this part, enabling more refrigerant to enter the aluminum alloy from the part of the copper tube exposed outside the aluminum alloy, and improving the ice-making efficiency.

[0010] The two ends of the copper tube are arranged in parallel, and symmetrically bent on both sides of the two ends, and evenly distributed into multiple parallel columns, so that the part of the copper tube inside the aluminum alloy is evenly distributed, making the ice-making efficiency of the ice tray uniform.

[0011] A plurality of long grooves are provided on the back surface of the ice tray, and each column of the copper tubes is wrapped in a groove wall of the long groove.

[0012] Support members are respectively provided at the four corners of the ice tray to facilitate the stable placement of the ice tray.

[0013] The beneficial effects of the present utility model are as follows: A die-cast liquid-cooled ice tray includes copper tubes and aluminum alloy die-cast to wrap the copper tubes. A part of the copper tubes is exposed outside the aluminum alloy. Multiple rows and columns of ice cells are die-cast on the front surface of the aluminum alloy. A heat insulation material layer is sprayed on the back surface of the aluminum alloy, and a Teflon coating is sprayed on the front surface of the aluminum alloy. The aluminum alloy is integrally formed by die-casting. Even if it undergoes temperature differences of hot and cold alternation for a long time, it will not fall apart, solving the technical problem that the copper ice tray made of soldering is prone to falling apart and being damaged. The heat insulation material layer is sprayed on the back surface of the aluminum alloy, and the heat insulation material layer is carbon fiber coating or resin coating, which can reduce the heat exchange between the back surface of the aluminum alloy and the external environment, promote heat exchange through the front surface, that is, the ice cell surface, improve the heat exchange efficiency of the ice cell surface, thereby improving the ice-making efficiency, reducing the loss of the refrigerant entering the copper tubes, and reducing the ice-making cost. The front surface of the aluminum alloy, that is, the surface of the ice cells, is sprayed with a Teflon coating. The Teflon coating has non-stick properties, making the formed ice cubes easy to fall off from the ice cells, and can also effectively avoid the formation of scale residues in the ice cells, polluting the ice cubes. The Teflon coating is preferably food-grade, so that the made ice cubes can meet the food-grade hygiene standards, being clean and hygienic.

A Teflon coating is sprayed on the front surface of the aluminum alloy 20, that is, the ice cell surface. When the ice tray is in use, the refrigerant is injected through the part 11 of the copper tube 10 exposed outside the aluminum alloy 20, and flows into the part of the copper tube 10 wrapped in the aluminum alloy 20, gradually cooling the copper tube 10, the aluminum alloy 20 and the water in the ice cells 22, so that the water condenses into ice to achieve the purpose of making ice.

The ice tray is integrally formed by die-casting, solving the risk and accident of the ice tray formed by soldering copper sheets in the prior art from falling apart and being damaged after long-term repeated exposure to hot and cold changes.

A Teflon coating is sprayed on the front surface of the aluminum alloy 20, that is, the ice cell surface. The Teflon coating has non-stick properties, making the formed ice cubes easy to fall off from the ice cells 22, and can also effectively avoid the formation of scale residues in the ice cells 22, polluting the ice cubes. The Teflon coating is preferably food-grade, so that the made ice cubes can meet the food-grade hygiene standards, being clean and hygienic.

[0024] Preferably, the heat-insulating material layer is a resin coating or a carbon fiber coating.

[0025] Preferably, referring to Figure 5 , the part of the copper tube 10 wrapped in the aluminum alloy 20 is bent into multiple parallel columns, thereby increasing the length of this part, enabling more refrigerant to enter the aluminum alloy from the part of the copper tube exposed outside the aluminum alloy, improving the ice-making efficiency.

[0026] Preferably, referring to Figure 5, the part 11 of the copper tube 10 exposed outside the aluminum alloy, that is, the two ends of the copper tube 10 are arranged in parallel, and are symmetrically bent on both sides of the two ends, and are evenly distributed in multiple parallel columns, so that the part of the copper tube 10 inside the aluminum alloy 20 is evenly distributed, making the ice-making efficiency of the ice tray uniform.

[0027] Referring to Figure 2 , a plurality of long grooves 21 are provided on the back surface of the aluminum alloy, and each column of the copper tubes 10 is wrapped in a groove wall 24 of the long groove 21, so as to space apart the parallel copper tubes 10, with a beautiful shape.
