Description

Technical Field

[0001] The utility model relates to the field of snow melting machines, in particular to an evaporator structure for a snow melting machine and the snow melting machine. Background Art

[0002] Snow melters are important equipment used in the catering industry for making cold drinks such as smoothies. The evaporator is the core component of its refrigeration system. Through direct contact with the slurry, the evaporator absorbs heat from the slurry to achieve cooling. Traditional evaporators usually adopt an inner and outer barrel structure, with the refrigerant flowing in the interlayer between the inner and outer barrels to absorb heat and cool the machine. However, this design has some problems. For example, the welded connection may bring the risk of leakage, which in turn leads to food safety hazards and difficulties in equipment maintenance. To address these problems, some evaporators use a structure with an evaporation tube inside the outer barrel. However, in actual processing, it is difficult to achieve the ideal roundness and coaxiality of both the evaporation tube and the outer barrel. As a result, gaps are inevitably generated between the inner wall of the outer barrel and the outer wall of the evaporation tube. These gaps not only reduce the efficiency of heat transfer, but also lead to unstable cooling effect due to the difference in gap size.

[0003] Therefore, it is necessary to develop an evaporator structure for a snow melter to solve the problems of structural gap and unstable refrigeration effect. Utility Model Content

[0007] Furthermore, the scheme describes an evaporator structure for a snow melter, wherein the evaporation tube is a copper tube, and under the elastic action of the cylindrical copper tube, the outer wall of the evaporation tube abuts against the inner wall of the outer barrel.

[0010] Furthermore, the scheme describes an evaporator structure for a snow melter, wherein an opening is provided on one side of the outer barrel, and the evaporation tube includes an inlet pipe and an outlet pipe extending through the opening to the outside of the outer barrel.

[0011] Furthermore, the scheme describes an evaporator structure for a snow melter, wherein the outlet pipe extends along the inner cavity of the cylindrical evaporator tube to the outside of the opening, part of the outlet pipe is arranged adjacent to part of the inlet pipe, and the evaporator tube portion is spirally coiled in the inner cavity of the outer barrel.

[0012] Furthermore, the scheme describes an evaporator structure for a snow melter, wherein the diameter of the inlet pipe is larger than the diameter of the outlet pipe.

[0013] Furthermore, the scheme describes an evaporator structure for a snow melter, wherein a portion of the outlet pipe is spirally coiled around a portion of the inlet pipe.

[0022] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0023] like Figure 1-4 An evaporator structure for a snow melter is shown, comprising a cylindrical outer barrel 1, the outer barrel 1 defining an inner barrel cavity 11, and an evaporation assembly 2 located within the inner barrel cavity 11. The evaporation assembly 2 comprises an evaporation tube 21 located within the inner barrel cavity 11. A portion of the evaporation tube 21 is arranged in a circuitous manner to form a cylindrical shape, with both ends of the evaporation tube 21 extending from the same end of the inner barrel cavity 11.

[0024] The outer wall of the evaporation tube 21 abuts against the inner wall of the outer barrel 1 , and a thermal grease 3 is provided in the gap between the outer wall of the evaporation tube 21 and the inner wall of the outer barrel 1 .

[0025] The present invention arranges a circuitous evaporator tube 21 in the inner cavity 11 of the outer barrel, and the outer barrel inner cavity 11 and the part of the evaporator tube 21 in contact with the outer barrel inner cavity 11 are both cylindrical structures. This arrangement increases the contact area between the evaporator tube 21 and the inner wall of the outer barrel 1, thereby improving the heat exchange efficiency; in addition, by filling thermal grease 3 between the outer wall of the evaporator tube 21 and the inner wall of the outer barrel 1, the gap problem caused by processing errors is effectively solved, thereby ensuring the improvement of the overall heat transfer efficiency of the evaporator, and ensuring the uniformity and stability of the cooling effect; furthermore, both ends of the evaporator tube 21 extend from one end of the inner cavity of the evaporator tube 21. This arrangement is conducive to the flow of refrigerant, ensuring the smooth circulation of the refrigerant in the evaporator tube 21, thereby improving the refrigeration cycle efficiency.

[0026] Specifically, the present invention fills thermal grease 3 between the outer barrel 1 and the evaporating tube 21. This arrangement effectively fills the gap between the outer barrel 1 and the evaporating tube 21 caused by inevitable processing errors in the manufacturing process. If these gaps are not filled, the contact between the outer barrel 1 and the evaporating tube 21 will be insufficient, so that the heat of the slurry cannot be continuously and effectively transferred to the evaporating tube 21, thereby affecting the uniformity of the cooling effect of the evaporator. By filling the thermal grease 3, the gap between the outer barrel 1 and the evaporating tube 21 can be effectively eliminated, ensuring that the contact between the evaporating tube 21 and the outer barrel 1 is more sufficient, thereby greatly improving the heat transfer efficiency.

[0027] The utility model increases the contact area between the evaporator tube 21 and the outer barrel 1 by arranging the evaporator tube 21 in a circuitous manner into a cylindrical structure and placing it in the inner cavity 11 of the outer barrel which is also in a cylindrical structure, thereby improving the heat exchange efficiency; further, the circuitous arrangement of the evaporator tube 21 increases the path of the refrigerant flowing through the evaporator tube 21, which not only increases the circulation volume of the refrigerant, but also prolongs the flow time of the refrigerant in the evaporator tube 21, so that the evaporator tube 21 can more fully absorb the heat in the slurry, thereby improving the cooling capacity and efficiency of the evaporator.

[0028] The present invention adopts thermal grease 3 as the heat-conducting medium. Since the thermal grease 3 has excellent thermal conductivity and fluidity, this arrangement ensures that the heat conduction between the evaporating tube 21 and the outer barrel 1 is more efficient, effectively reduces the thermal resistance, and improves the heat exchange efficiency; furthermore, the fluidity of the thermal grease also enables it to better fill the tiny gap between the evaporating tube 21 and the outer barrel 1 caused by processing errors or equipment vibrations, thereby ensuring the thermal stability of the evaporator during long-term operation.

[0029] Further, such as Figure 1-4 The evaporator structure shown is for a snow melter, wherein the evaporation tube 21 is a copper tube. Under the elastic action of the cylindrical copper tube, the outer wall of the evaporation tube 21 abuts against the inner wall of the outer barrel 1.

[0030] In the present invention, the evaporation tube 21 is made of copper tube, and the radial dimension of the outer wall of the cylindrical evaporation tube 21 is set to be slightly larger than the radial dimension of the inner wall of the outer barrel 1. The evaporation tube 21 is nested in the outer barrel 1, and the elastic characteristics of the copper tube can be utilized to make the outer wall of the evaporation tube 21 in close contact with the inner wall of the outer barrel 1. This setting not only ensures the relative fixation between the evaporation tube 21 and the outer barrel 1, reduces the risk of leakage caused by welding connection, and thus improves the safety of the equipment, but also the high thermal conductivity of the copper tube helps to improve the heat exchange efficiency, so that the heat of the slurry can be transferred to the evaporation tube 21 more quickly, thereby improving the uniformity and stability of the cooling effect of the evaporator.

[0031] Further, such as Figure 1-4 The evaporator structure shown is for a snow melter, wherein the inner cavity 11 of the outer barrel is cylindrical, and the outer shape of the evaporation tube 21 is adapted to the shape of the inner cavity 11 of the outer barrel.

[0032] In the present invention, the inner cavity 11 of the outer barrel is set to be cylindrical, which not only facilitates processing and reduces production costs, but also facilitates the installation and maintenance of the evaporation tube 21; further, the outer shape of the evaporation tube 21 is adapted to the cylindrical inner cavity 11 of the outer barrel, and this setting ensures that there is a larger contact area between the evaporation tube 21 and the outer barrel 1, thereby improving the heat exchange efficiency.

[0033] Further, such as Figure 1-4 An evaporator structure for a snow melter is shown, in which a circuitously arranged cylindrical evaporation tube 21 has multiple tube segments, and adjacent tube segments and the inner wall of the outer barrel 1 form an annular gap. As one of the specific embodiments but not limiting, thermal grease 3 is also provided in the annular gap.

[0034] The utility model provides the evaporator tube 21 with multiple tube sections, so that the contact between the evaporator tube 21 and the outer barrel 1 is closer, the heat exchange area is increased, and the heat of the slurry can be more fully transferred to the evaporator tube 21, thereby improving the cooling capacity and efficiency of the evaporator; further, the thermal grease 3 is also filled in the annular gap formed by the adjacent tube sections and the inner wall of the outer barrel 1, thereby increasing the heat conduction area of ​​the evaporator tube 21 and further enhancing the heat conduction effect, so that the evaporator can more efficiently absorb the heat in the slurry and transfer it to the refrigerant, thereby achieving a better cooling effect.

[0035] Further, such as Figure 1-4 The evaporator structure shown is for a snow melter, wherein an opening 12 is provided on one side of the outer barrel 1 , and the evaporation pipe 21 includes an inlet pipe 22 and an outlet pipe 23 extending through the opening 12 to the outside of the outer barrel 1 .

[0036] The utility model provides an opening 12 on the outer barrel 1 and provides an inlet pipe 22 and an outlet pipe 23 extending to the outside of the opening 12 on the evaporator tube 21. This setting realizes the docking of the evaporator tube 21 with the external refrigerant supply system, which not only simplifies the installation process of the evaporator, but also ensures that the refrigerant can flow into and out of the evaporator tube 21 efficiently and smoothly, thereby improving the refrigeration cycle efficiency of the evaporator.

[0037] Further, such as Figure 1-4 The evaporator structure shown is for a snow melter, wherein the outlet pipe 23 extends along the inner cavity of the cylindrical evaporation tube 21 to the outside of the opening 12, part of the outlet pipe 23 is arranged adjacent to part of the inlet pipe 22, and part of the evaporation tube 21 is spirally coiled in the inner cavity 11 of the outer barrel.

[0038] The utility model helps to form a more compact refrigerant circulation path by arranging part of the outlet pipe 23 and part of the inlet pipe 22 adjacent to each other, which can better optimize the use of the internal space of the evaporator; further, by arranging the evaporating tube 21 spirally coiled in the inner cavity 11 of the outer barrel, the contact area between the evaporating tube 21 and the outer barrel 1 is increased, thereby enhancing the heat exchange effect and ensuring the uniformity and stability of the cooling effect.

[0039] Further, such as Figure 1-4 An evaporator structure for a snow melter is shown, wherein the diameter of the inlet pipe 22 is larger than the diameter of the outlet pipe 23 .

[0040] Further, such as Figure 1-4 The evaporator structure shown is for a snow melter, wherein a portion of the outlet pipe 23 is spirally wound around a portion of the inlet pipe 22 .

[0041] The utility model spirally coils the outlet pipe 23 around part of the outside of the inlet pipe 22, thereby extending the refrigerant outflow path, helping to release more heat after the refrigerant leaves the evaporator tube 21, thereby improving the utilization rate of the refrigerant; furthermore, this arrangement also makes the pipeline layout more compact and saves space.

[0042] Further, such as Figure 1-4 The snow melter shown includes a shell, and one side of the outer barrel 1 is further provided with a fixing end 13 and a fixing hole 14.

[0043] The utility model provides a shell for the snow melter and provides a fixing end 13 and a fixing hole 14 for fixing to the shell on one side of the outer barrel 1. This arrangement simplifies the connection and fixing process between the evaporator and the snow melter shell, so that the evaporator can be easily disassembled and repaired; further, this arrangement also ensures the stability of the evaporator during the operation of the snow melter, avoiding the risk of displacement of the evaporator due to vibration of the snow melter, thereby causing malfunction of the snow melter.

[0044] like Figure 1-4 As shown, the implementation of this embodiment is as follows:

[0045] Example 1

[0046] An evaporator structure for a snow melter includes an outer barrel 1, an evaporation assembly 2, and thermal grease 3 filled between the outer barrel and the evaporation assembly 2. In this embodiment, the evaporation assembly 2 primarily comprises an evaporation tube 21 spirally wound within the outer barrel's inner cavity 11. To enhance thermal conductivity, the cross-section of each section of the evaporation tube 21 is designed as a straight-edged ellipse, increasing the contact area between the evaporation tube 21 and the inner wall of the outer barrel 1, thereby increasing the contact area and improving thermal conductivity. The outer barrel's inner cavity 11 is cylindrical, and the evaporation tube 21's shape matches it. The evaporation tube 21 and the outer barrel's inner cavity 11 have an interference fit. When the evaporation tube 21 is placed into the outer barrel's inner cavity 11 through the opening 12 of the outer barrel 1, the evaporation tube 21 is made of brass, which has a certain elasticity. This not only ensures that the evaporation tube 21 is firmly fixed to the outer barrel's inner cavity 11, but also ensures that the evaporation tube 21 fits tightly with the outer barrel 1. An inlet pipe 22 and an outlet pipe 23 are provided at one end of the evaporation tube 21 , wherein the outlet pipe 23 is spirally wound around a portion of the outside of the inlet pipe 22 , and both of them pass through the opening 12 of the outer tub 1 and extend to the outside.

[0047] In actual operation, the outer side of the outer barrel 1 is covered with slurry that needs to be cooled, and then the refrigerant is introduced from the inlet pipe 22 through the cooling system. The refrigerant enters the evaporating tube 21 and flows inside. The heat of the slurry is transferred to the refrigerant through the outer barrel 1, the thermal grease 3 and the evaporating tube 21, thereby realizing the cooling of the slurry. Finally, the refrigerant flows out to the cooling system through the outlet pipe 23, thereby realizing circulation.

[0048] Example 2

[0049] The structure and operation mode of the evaporator in this embodiment are the same as those in the first embodiment. In addition, the snow melter in this embodiment includes a shell, and a fixed end 13 and a fixed hole 14 are provided on one side of the outer barrel 1. The outer barrel 1 can be fixed to the shell through the fixed end 13 and the fixed hole 14 so that the outer barrel 1 is fixed on the snow melter.

[0050] The above examples are merely used to further illustrate the technical content of the present invention for easier understanding by the reader. However, they do not limit the implementation of the present invention to these examples. Any technical extension or reinvention based on the present invention is protected by the present invention. The scope of protection of the present invention shall be determined by the claims.
