Description

Technical Field

[0001] This utility model relates to the field of snow melting machine technology, specifically a barrel-type evaporator structure for a snow melting machine. Background Technology

[0002] A slush machine is a machine used to make various fruit juices into refreshing and delicious slush-like beverages. It mainly consists of a material tank, an evaporator, and a stirrer. The evaporator, as part of the refrigeration system of the slush machine, is placed inside the material tank and is used to refrigerate the food ingredients inside the material tank during operation.

[0003] Currently, the evaporators of snow melting machines mainly have an inner and outer barrel structure. The refrigerant enters the space between the inner and outer barrels and evaporates, absorbing heat from the food ingredients through the outer wall of the outer barrel to cool them. However, this type of evaporator with an inner and outer barrel structure has the following disadvantages: First, the inner and outer barrels need to be sealed by welding, which not only requires high production technology but also poses a risk of refrigerant leakage. Second, there are multiple dead corners in the space between the inner and outer barrels. The lubricating oil flowing through these dead corners cannot return to the compressor, causing oil accumulation and affecting the heat exchange efficiency of the product. At the same time, the amount of lubricating oil returning to the compressor will also decrease, thereby increasing the wear of the compressor's moving parts and affecting the product's service life.

[0004] Therefore, further improvements are necessary. Summary of the Invention

[0005] The present invention aims to provide a barrel-type evaporator structure for a snow melting machine to overcome the shortcomings of the prior art.

[0006] A barrel-type evaporator structure for a snow melting machine designed for this purpose includes a cylindrical outer barrel, an evaporation tube installed inside the cylindrical outer barrel, the evaporation tube being an integrally formed coiled spiral tube and embedded inside the cylindrical outer barrel, the outer wall of the evaporation tube being in close contact with the inner wall of the cylindrical outer barrel, and the evaporation tube extending along the outside of the cylindrical outer barrel having an inlet end and an outlet end.

[0007] The inner cavity of the cylindrical outer barrel is cylindrical, and the outer shape of the evaporator tube matches the shape of the inner cavity of the cylindrical outer barrel.

[0008] The inner diameter of the cylindrical outer barrel is smaller than the outer diameter of the evaporator tube; the deformed evaporator tube is embedded inside the cylindrical outer barrel.

[0009] The outer diameter of the evaporator tube is 1 mm larger than the inner diameter of the cylindrical outer barrel.

[0010] The height of the spiral of the evaporator tube is equal to or less than the depth inside the cylindrical outer barrel.

[0011] The inner wall of the cylindrical outer barrel is coated with a thermally conductive silicone layer; the outer wall of the evaporator tube is tightly attached to the inner wall of the cylindrical outer barrel through the thermally conductive silicone layer.

[0012] Thermally conductive adhesive paper is attached to the inner wall of the evaporator tube. The thermally conductive adhesive paper is attached to the inner wall of the evaporator tube and passes through the gap between each adjacent section of the evaporator tube before being attached to the inner wall of the cylindrical outer barrel.

[0013] The thermally conductive adhesive paper is made of aluminum foil.

[0014] The inner wall of the evaporator tube is also filled with foam material.

[0015] One end of the cylindrical outer barrel has an opening; the evaporator tube is embedded in the cylindrical outer barrel through the opening; the inlet end and the outlet end extend to the outside of the cylindrical outer barrel through the opening.

[0016] The evaporator tube of this invention is an integrally formed coiled spiral tube, which effectively guides the refrigerant entering the tube, reducing refrigerant retention and ensuring more uniform refrigerant flow. Simultaneously, the outer wall of the evaporator tube is tightly fitted to the inner wall of the cylindrical outer casing, increasing the contact area and allowing the evaporator tube to absorb heat from the cylindrical outer casing as much as possible, thereby improving refrigeration efficiency. Furthermore, it can push the compressor lubricating oil in the evaporator tube back to the compressor, ensuring normal compressor operation, increasing its service life, and reducing operating noise. Moreover, the evaporator tube is directly embedded in the cylindrical outer casing, ensuring a stable assembly and eliminating the need for welding, effectively simplifying the assembly process, facilitating manufacturing, and effectively reducing the risk of evaporator tube leakage, making the product safer, more reliable, and highly practical.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] See Figures 1-3 The barrel-type evaporator structure of this snow melting machine includes a cylindrical outer barrel 1, and an evaporation tube 2 is provided inside the cylindrical outer barrel 1. The evaporation tube 2 is an integrally formed coiled spiral tube and is embedded in the cylindrical outer barrel 1. The outer wall of the evaporation tube 2 is in close contact with the inner wall of the cylindrical outer barrel 1. The evaporation tube 2 extends along the outside of the cylindrical outer barrel 1 and has an inlet end 2.1 and an outlet end 2.2.

[0022] In this embodiment, the evaporator tube 2 is an integrally formed coiled spiral tube, which can effectively guide the refrigerant entering the tube, reduce the residence time of the refrigerant in the evaporator tube 2, and make the refrigerant flow more evenly in the evaporator tube 2. At the same time, the outer wall of the evaporator tube 2 is in close contact with the inner wall of the cylindrical outer barrel 1, thereby increasing the contact area between the two, so that the evaporator tube 2 can absorb as much heat as possible from the cylindrical outer barrel 1, thereby improving the cooling efficiency. In addition, it can also push the compressor lubricating oil in the evaporator tube 2 back to the compressor, thereby ensuring the normal operation of the compressor, increasing its service life, and reducing operating noise. Moreover, the evaporator tube 2 is directly embedded in the cylindrical outer barrel 1, which not only ensures a stable assembly, but also avoids welding and other operations, effectively simplifying the assembly process, facilitating manufacturing, and effectively reducing the risk of leakage of the evaporator tube 2, making the product safer, more reliable, and more practical.

[0023] The inner cavity of the cylindrical outer barrel 1 is cylindrical, and the outer shape of the evaporator tube 2 matches the shape of the inner cavity of the cylindrical outer barrel 1, which facilitates the processing and assembly of the cylindrical outer barrel 1 and the evaporator tube 2. In other embodiments, the cylindrical outer barrel 1 can also be configured with other suitable cylindrical structures as needed, and is not limited to this.

[0024] The inner diameter of the cylindrical outer barrel 1 is smaller than the outer diameter of the evaporator tube 2; the deformed evaporator tube 2 is embedded inside the cylindrical outer barrel 1.

[0025] Specifically, the outer diameter of the evaporator tube 2 is 1 mm larger than the inner diameter of the cylindrical outer barrel 1.

[0026] In this embodiment, the evaporator tube 2 can be securely assembled with the cylindrical outer barrel 1 through an interference fit, eliminating the need for additional fixing and further facilitating their processing, manufacturing, and assembly. In other embodiments, the outer diameter of the evaporator tube 2 can be smaller than the inner diameter of the cylindrical outer barrel 1, and the evaporator tube 2 can be fixed to the cylindrical outer barrel 1 using methods such as gluing or spot welding. Alternatively, the relative fixation between the evaporator tube 2 and the cylindrical outer barrel 1 can be achieved through limiting structures on other components in the snow melting machine. It is not limited to these methods. It should be noted that in this embodiment, both the inner and outer diameters are diameters, consistent with the understanding and habits of those skilled in the art.

[0027] The spiral height of the evaporator tube 2 is equal to or less than the internal depth of the cylindrical outer barrel 1.

[0028] In this embodiment, the spiral height of the evaporator tube 2 is equal to the internal depth of the cylindrical outer barrel 1, so that the spiral part of the evaporator tube 2 can be completely placed inside the cylindrical outer barrel 1, thereby increasing the effective contact area between the evaporator tube 2 and the cylindrical outer barrel 1, and thus improving the heat exchange efficiency.

[0029] The inner wall of the cylindrical outer barrel 1 is coated with a thermally conductive silicone layer 1.1; the outer wall of the evaporator tube 2 is in close contact with the inner wall of the cylindrical outer barrel 1 through the thermally conductive silicone layer 1.1.

[0030] In this embodiment, the thermally conductive silicone layer 1.1 can improve the thermal conductivity between the evaporator tube 2 and the cylindrical outer barrel 1, which is beneficial to heat transfer.

[0031] Thermally conductive adhesive paper 2.3 is attached to the inner wall of the evaporator tube 2. The thermally conductive adhesive paper 2.3 is attached to the inner wall of the evaporator tube 2 and passes through the gap between each adjacent section of the evaporator tube 2 before being attached to the inner wall of the cylindrical outer barrel 1.

[0032] In this embodiment, the thermally conductive adhesive paper 2.3 can increase the area of ​​heat absorption of the evaporator tube 2, thereby further improving the cooling efficiency.

[0033] Thermally conductive adhesive paper 2.3 is made of aluminum foil, which has excellent thermal conductivity, is not easily corroded by iron, and helps extend the product's service life and reduce food safety risks. However, thermally conductive adhesive paper 2.3 can also be made of other suitable thermally conductive materials such as copper foil, and is not limited to these.

[0034] The inner wall of the evaporator tube 2 is also filled with foaming material, which further improves the assembly stability between the cylindrical outer barrel 1 and the evaporator tube 2, and also prevents the loss of cold energy.

[0035] The cylindrical outer barrel 1 has an outer barrel opening 1.2 at one end; the evaporator tube 2 is embedded in the cylindrical outer barrel 1 through the deformation of the outer barrel opening 1.2; the inlet end 2.1 and the outlet end 2.2 extend to the outside of the cylindrical outer barrel 1 through the outer barrel opening 1.2, which facilitates the connection of the inlet end 2.1 and the outlet end 2.2 with the compressor's circulation pipeline, making installation and use convenient.

[0036] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
