Refrigeration unit with integrated refrigerant flow channel

Abstract

This disclosure provides a refrigeration device with an integrated refrigerant flow channel, comprising: a container including a cylindrical body, a first cap, and a second cap; the cylindrical body having a first end and a second end; the first cap being attached to the first end and the second cap being attached to the second end; an outer shell, the inner surface of which is fitted onto the outer surface of the cylindrical body; an arched wall with a fixed pitch and spirally protruding outwards around the periphery of the outer shell; the inner surface of the arched wall being spaced apart from the outer surface of the cylindrical body to form a refrigerant flow channel; a water inlet connector attached to the container; a water outlet connector attached to the container; a refrigerant inlet connector attached to the arched wall of the outer shell and communicating with the refrigerant flow channel; and a refrigerant outlet connector attached to the arched wall of the outer shell and communicating with the refrigerant flow channel.

Claims

1. A refrigeration device with an integrated refrigerant flow channel, comprising: A container comprising a cylindrical body, a first cap, and a second cap, the cylindrical body having a first end and a second end opposite to each other, the first cap being attached to and closing the first end, and the second cap being attached to and closing the second end; an outer shell attached to the outer periphery of the container, the outer shell having a first opening and a second opening opposite to each other, the inner surface of the outer shell fitting onto the outer surface of the cylindrical body, the first opening being attached to the first end, and the second opening being attached to the second end, the outer shell having a fixed-pitch, spirally protruding arched wall around its periphery, the inner surface of the arched wall being spaced apart from the outer surface of the cylindrical body to form a refrigerant flow channel; a water inlet connector attached to the container and allowing drinking water to enter the container; and a water outlet connector attached to the container and allowing drinking water to flow out of the container. A refrigerant inlet connector is attached to the arched wall of the housing near the first opening and communicates with the refrigerant channel; and a refrigerant outlet connector is attached to the arched wall of the housing near the second opening and communicates with the refrigerant channel.

2. The refrigeration device with an integrated refrigerant flow channel as described in claim 1, wherein, The cylinder body is made of stainless steel and is in the shape of a hollow cylindrical tube. The diameter of the cylinder body is smaller than the length of the cylinder body. The first cap and the second cap are both made of stainless steel and are in the shape of an arc-shaped disc. The first cap is welded to the first end and the second cap is welded to the second end. The outer shell is made of stainless steel and is in the shape of a hollow cylindrical tube. The first opening is welded to the first end and the second opening is welded to the second end.

3. The refrigeration device with an integrated refrigerant flow channel as described in claim 1, wherein, A first fold is formed around the outer periphery of the first cap adjacent to the inner surface of the cylinder, and a second fold is formed around the outer periphery of the second cap adjacent to the inner surface of the cylinder.

4. A refrigeration device with an integrated refrigerant flow channel as described in claim 1, wherein, The cross-section of the arch wall is semi-circular.

5. A refrigeration device with an integrated refrigerant flow channel as described in claim 1, wherein, The water inlet connector is welded to the cylinder body near the first end. The water inlet connector extends along the radial direction of the cylinder body. A portion of the water inlet connector is located inside the cylinder body, and a portion of the water inlet connector is located outside the cylinder body. The water outlet connector is welded to the cylinder body near the second end. The water outlet connector extends along the radial direction of the cylinder body. A portion of the water outlet connector is located inside the cylinder body, and a portion of the water outlet connector is located outside the cylinder body. The water outlet connector and the water inlet connector are located on the same side around the outside of the cylinder body, and the length of the water outlet connector inside the cylinder body is greater than the length of the water inlet connector inside the cylinder body.

6. A refrigeration device with an integrated refrigerant flow channel as described in claim 5, wherein, The refrigerant outlet connector and the water outlet connector are located in opposite positions to each other, and the refrigerant inlet connector and the refrigerant outlet connector are located at different circumferential positions on the outer casing.

7. A refrigeration device with an integrated refrigerant flow channel as described in claim 6, wherein, The refrigeration device further includes a drain outlet located on the cylinder body relative to the water inlet connector. The drain outlet extends through both the cylinder body and the outer casing, and the outer casing is welded to the periphery of the drain outlet on the cylinder body.

8. A refrigeration device with an integrated refrigerant flow channel as described in claim 1, wherein, The first cap is connected to a temperature rod at the center position, and the temperature rod extends along the axis of the cylinder from the first end to the second end.

9. A refrigeration device with an integrated refrigerant flow channel as described in claim 1, wherein, The water inlet connector is welded to the first cover. The water inlet connector extends along an axis parallel to the cylinder body. A portion of the water inlet connector is located inside the first cover, and a portion of the water inlet connector is located outside the first cover.
