Description

Technical Field

[0001] This utility model relates to an evaporator, specifically a cylinder-type evaporator distributed on the side and bottom of a refrigeration cylinder. Background Technology

[0002] Evaporators are essential refrigeration components for ice cream machines, slush machines, and cold drink machines. A common evaporator is a heat exchange coil wound around the outer wall of the refrigeration cylinder. The refrigerant inside the coil exchanges heat and cold through circulation. However, this type of evaporator suffers from insufficient contact between the refrigerant flow channel and the refrigeration cylinder, resulting in uneven heat exchange and low heat exchange efficiency.

[0003] Chinese patent CN104266437A discloses an "Integral High-Efficiency Cold Drink Tank with Evaporator," which features a cold drink tank body composed of inner and outer tank layers welded together to form a sealed cavity. The inner wall of the outer tank layer has spiral grooves, which, together with the outer wall of the inner tank layer, form a spiral fluid channel. While this cold drink tank body improves heat exchange efficiency to some extent, the heat exchange area is still relatively small for the entire tank, and the heat exchange uniformity needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a cylinder-type evaporator distributed on the side and bottom of a refrigeration cylinder, which can increase the heat exchange area and improve the heat exchange efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions.

[0006] A sleeve-type evaporator distributed on the side and bottom of a refrigeration cylinder includes a molded outer shell disposed outside the cylinder body of the refrigeration cylinder. The molded outer shell surrounds and covers the side and bottom of the cylinder body of the refrigeration cylinder. The edge of the molded outer shell is welded to the cylinder body of the refrigeration cylinder, so that a sealed cavity with a spiral fluid channel is formed between the molded outer shell and the cylinder body of the refrigeration cylinder. The spiral fluid channel is distributed on the side and bottom of the cylinder body of the refrigeration cylinder. One end of the spiral fluid channel is connected to a refrigerant inlet pipe, and the other end is connected to a refrigerant outlet pipe.

[0007] This invention welds the cylinder body of the refrigeration cylinder to the molded outer shell into a single structure. The resulting spiral fluid channels are distributed on the sides and bottom of the cylinder body, increasing the contact area between the refrigeration cylinder and the refrigerant, thus improving heat exchange efficiency. Because both the sides and bottom of the refrigeration cylinder can exchange heat with the refrigerant, the heat exchange uniformity is also better.

[0008] This utility model also has the following preferred designs:

[0009] In this invention, the bottom surface of the molded outer shell is welded to the bottom surface of the refrigeration cylinder body along the edge of the spiral fluid channel. Because the bottom surface of the refrigeration cylinder body is flat, the pressure of the refrigerant on the molded outer shell may cause a gap to form between the bottom surface of the molded outer shell and the bottom surface of the cylinder body. Therefore, welding the bottom surface of the molded outer shell to the bottom surface of the refrigeration cylinder body along the edge of the spiral fluid channel can avoid the formation of this gap and ensure that the refrigerant flows along the designed spiral fluid channel.

[0010] In this invention, the refrigerant inlet pipe is connected to the bottom surface of the molded outer shell, and the refrigerant outlet pipe is connected to the side surface of the molded outer shell.

[0011] The refrigeration cylinder of this invention has a drain outlet on one side of its bottom, and the drain outlet is connected to a drain pipe, which should be fitted with a drain plug. The purpose of this drain pipe is to facilitate the discharge of cleaning fluid after cleaning the refrigeration cylinder body.

[0012] The refrigeration cylinder of this invention has a shaft hole at the center of the bottom surface for installing a stirrer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model welds the cylinder body of the refrigeration cylinder to the molded outer shell into an integral structure, and the spiral fluid channels formed are distributed on the side and bottom of the cylinder body of the refrigeration cylinder. The contact area between the refrigeration cylinder and the refrigerant is larger, the heat exchange efficiency is higher, and the heat exchange uniformity is better.

[0015] 2. In this invention, the bottom surface of the molded outer shell is welded to the bottom surface of the refrigeration cylinder along the edge of the spiral fluid channel, which can avoid gaps between the bottom surface of the molded outer shell and the bottom surface of the cylinder, and ensure that the refrigerant flows along the designed spiral fluid channel.

[0016] 3. The bottom of the refrigeration cylinder of this utility model is provided with a drain outlet on one side, which facilitates the discharge of cleaning liquid and improves the cleaning efficiency of the refrigeration cylinder. Attached Figure Description
