[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] Combination Figures 1 to 6 According to an embodiment of the present invention, the refrigeration tank 100 includes a first shell 10 and a second shell 20. The second shell 20 is disposed outside the first shell 10 and connected to the first shell 10. A heat exchange channel 110 is formed between the first shell 10 and the second shell 20, and the heat exchange channel 110 has an inlet 102 and an outlet 103. Specifically, the second shell 20 is disposed outside the refrigeration tank 100, and the first shell 10 is disposed inside the refrigeration tank 100. The inner first shell 10 is connected to the outer second shell 20. A heat exchange channel 110 can be formed between the outer side of the first shell 10 and the inner side of the second shell 20. The heat exchange medium can enter the heat exchange channel 110 from the inlet 102, exchange heat with the medium outside the refrigeration tank 100, and then flow out from the outlet 103. Thus, by integrating the heat exchange channel 110 onto the refrigeration tank 100 of the evaporator 1000, the structure is simplified and the heat exchange effect is improved.

[0032] Specifically, in the relevant technology, the evaporator includes a barrel and a coil installed inside the barrel. The heat exchange medium flows inside the coil, and the coil inside the barrel exchanges heat with the outside of the barrel. This makes the structure of the evaporator relatively complex, and the heat exchange medium is separated from the outside by the outer wall of the coil, the barrel wall, and the gap between the coil and the barrel, resulting in low heat exchange efficiency.

[0033] According to an embodiment of the present invention, the refrigeration tank 100 of the evaporator 1000 can have the heat exchange channel 110 directly disposed on the refrigeration tank 100, allowing the external medium to directly contact the refrigeration tank 100 for heat exchange, which helps reduce energy loss. Furthermore, by applying the refrigeration tank 100 of the present invention to the evaporator 1000, the structure of the evaporator 1000 can be simplified. During assembly, there is no need to separately install a heat exchange device with a heat exchange channel, which simplifies the assembly of the evaporator 1000.

[0034] In some embodiments of this utility model, the refrigeration tank 100 can be made of stainless steel. By constructing the refrigeration tank 100 into a double-layer structure and setting a heat exchange channel 110 between the double-layer structure, the structural strength of the refrigeration tank 100 can be improved, and the refrigeration tank 100 can also have a heat exchange function. In actual application, the water that needs to exchange heat can achieve heat exchange by contacting the outer wall of the refrigeration tank 100, which is conducive to improving the heat exchange efficiency.

[0035] Combination Figure 1 and Figure 2In some embodiments of this utility model, the refrigeration tank 100 is cylindrical, which is beneficial for increasing the heat exchange area and improving the heat exchange effect. Furthermore, the heat exchange channel 110 is arranged circumferentially along the refrigeration tank 100 and constructed as a meandering channel. Specifically, the circumferential arrangement of the heat exchange channel 110 is beneficial for increasing the heat exchange area and improving the uniformity of heat exchange. The meandering construction of the heat exchange channel 110 can increase the area of ​​the heat exchange channel 110, thereby increasing the contact area between the heat exchange medium and the outside, and can also increase the flow time of the heat exchange medium in the channel, so that the heat exchange medium can fully and effectively exchange heat with the external medium, such as water.

[0036] In some embodiments of this utility model, combined with Figure 4 and Figure 6 The heat exchange channel 110 includes multiple axially extending U-shaped channels 101, which are connected end-to-end to form a meandering flow channel. Specifically, the U-shaped channels increase the path length of the heat exchange medium, thereby increasing the contact area of ​​the heat exchange medium along the axial wall of the refrigeration tank 100, improving the flow effect of the heat exchange medium, and thus improving heat exchange efficiency. The U-shaped channels 101 also reduce dead zones, avoiding local overheating or undercooling, and optimizing heat exchange. Multiple U-shaped channels 101 connected to form an S-shaped meandering flow channel improves the structural compactness of the heat exchange channel 110 and can extend the flow path and flow time of the heat exchange medium. In addition, the meandering flow channel can reduce thermal stress damage to the material, thus improving the structural stability of the refrigeration tank 100.

[0037] More specifically, inlet 102 is located at the beginning of the meandering flow channel, and outlet 103 is located at the end of the meandering flow channel. In this way, the heat exchange medium entering from inlet 102 can flow through this heat exchange channel and then be discharged from outlet 103, which helps to improve heat exchange efficiency. Inlet 102 and outlet 103 are located on the same side of the refrigeration tank 100 along the axial direction, which not only extends the flow path of the heat exchange medium but also facilitates the arrangement of the pipes connecting inlet 102 and outlet 103, thereby improving the compactness of the structure.

[0038] In some embodiments of this invention, at least one of the first housing 10 and the second housing 20 is provided with a protrusion, which forms a heat exchange channel 110, or the protrusion separates the first housing 10 and the second housing 20, and this separation forms a heat exchange channel 110. Specifically, the first housing 10 may be provided with a protrusion, and there may be a gap between the protrusion and the inner wall of the second housing 20 to form a heat exchange channel 110. Alternatively, the first housing 10 and the second housing 20 may be spaced apart, and at least one of the first housing 10 or the second housing 20 may be provided with a protrusion connected to the housing. The gap formed by the first housing 10 and the second housing 20 serves as a heat exchange channel 110 for the flow of the heat exchange medium. This invention is not limited to these embodiments.

[0039] Furthermore, combined Figure 2 In order to improve the heat exchange effect and overall structural consistency of the evaporator 1000, the second shell 20 is cylindrical, the first shell 10 is located inside the second shell 20, and the second shell 20 is provided with a radially inward protruding structure. In this way, the internal space of the refrigeration tank 100 can be fully utilized, and the exterior of the refrigeration tank 100 has an arc surface, which is conducive to improving the heat exchange effect, facilitating cleaning, and improving the aesthetics of the refrigeration tank 100.

[0040] Combination Figure 4 In some embodiments of this utility model, in the radial direction of the refrigeration tank 100, the first shell 10 includes a connecting portion 12 extending toward the second shell 20 and a protrusion 11 facing away from the second shell 20. The connecting portion 12 fits into the second shell 20, which can realize the connection between the first shell 10 and the second shell 20. The structure is simple and easy to construct. The protrusion 11 is arranged at intervals with the second shell 20. A heat exchange channel 110 is formed between the protrusion 11 and the inner wall of the second shell 20. Thus, the heat exchange channel 110 can be set on the barrel wall of the refrigeration tank 100, and the external structure of the refrigeration tank 100 is not affected, which helps to simplify the structure and improve the compactness of the structure.

[0041] In some embodiments of this utility model, combined with Figure 3 The connecting portion 12 divides the heat exchange channel 110 into a meandering channel, which helps to increase the heat exchange area of ​​the heat exchange channel 110 and, based on the increased heat exchange area, improves the tightness of the connection between the first shell 10 and the second shell 20. Specifically, the meandering channel extends along the axial direction of the refrigeration tank 100 and is arranged circumferentially. The connecting portion 12 can also be arranged axially and circumferentially, thereby improving the tightness of the connection between the first shell 10 and the second shell 20. More specifically, since the area of ​​the heat exchange channel 110 is relatively large, the connecting portion 12 located between the heat exchange channels 110 can improve the structural strength of the refrigeration tank 100. The connecting portion 12 can form a support between the two U-shaped channels, improving structural stability. In other words, after the first shell 10 and the second shell 20 are connected, the heat exchange channel 110 can be directly formed, which is simple in structure and conducive to improving structural stability.

[0042] Furthermore, the connecting part 12 is sealed to the second housing 20, which can construct the heat exchange channel 110 as a closed channel to realize the pipeline function of the channel. For example, the second housing 20 and the connecting part 12 can be bonded together, or the connecting part 12 can be fitted to the inner wall of the second housing 20, with no gap or interference fit between the two.

[0043] Combination Figure 3In some embodiments of this utility model, the second housing 20 includes a top wall 21 and a peripheral wall 22. The top wall 21 is connected to the peripheral wall 22, and the top wall 21 and the peripheral wall 22 form an accommodating cavity with one end open, so that other components can be accommodated inside the refrigeration tank 100. The end of the first housing 10 abuts against the top wall 21, which can realize the axial connection between the first housing 10 and the second housing 20. The connecting part 12 of the first housing 10 fits against the peripheral wall 22, which can realize the circumferential connection between the first housing 10 and the second housing 20, which is beneficial to improving the structural stability after connection.

[0044] In some embodiments of this utility model, combined with Figure 3 The peripheral wall 22 of the second housing 20 includes a first portion 221, a second portion 222, and a third portion 223 along the axial direction. The second portion 222 is located between the first portion 221 and the third portion 223. A heat exchange channel 110 is disposed in the second portion 222. The connecting portion 12 is in contact with the first portion 221 and the third portion 223, and partially in contact with the second portion 222. That is, in the first portion 221 and the third portion 223 where the heat exchange channel 110 is not provided, the connecting portion 12 of the first housing 10 is connected to the second housing 20, which can improve the stability of the connection between the first housing 10 and the second housing 20. In the second portion 222 of the peripheral wall 22, the part of the connecting portion 12 where the heat exchange channel 110 is not provided is connected to the second portion 222 of the second housing 20. Thus, while realizing the connection, a heat exchange channel 110 can be constructed between the first housing 10 and the second housing 20.

[0045] In some embodiments of this utility model, in the axial direction, the peripheral wall 22 of the second housing 20 is provided with a flange 23 at the end opposite to the top wall 21, and the flange 23 is provided with multiple notches 203. Specifically, the flange 23 can contact the refrigeration equipment when the evaporator 1000 is installed on the refrigeration equipment, thereby improving the stability of the installation. The notches 203 on the flange 23 can be used to install the refrigeration tank 100 of the evaporator 100 on the refrigeration equipment, thereby realizing the installation of the evaporator 1000. The structure is simple and easy to construct.

[0046] Furthermore, the outward extension of the flange 23 increases the assembly space, thereby facilitating assembly and maintenance.

[0047] According to a specific embodiment of the present invention, the refrigeration tank 100 has a second shell 20 that is cylindrical and a first shell 10 that is cylindrical. The first shell 10 includes a connecting portion 12 for fitting with the second shell 20 and a protrusion 11 that protrudes inward relative to the connecting portion 12. A heat exchange channel 110 is formed between the protrusion 11 and the inner wall of the second shell 20. In this way, the first shell 10 with a specific shape is connected or stacked inside the second shell 20, so that the refrigeration tank 100 of the evaporator 1000 can not only protect and support the evaporator 1000, but also be used to integrate the heat exchange structure. In addition, the heat exchange channel 100 is provided on the refrigeration tank 100, which can also provide support for the heat exchange structure of the evaporator, which is beneficial to improving the heat exchange effect, improving the structural stability, and simplifying the structure of the evaporator 1000.

[0048] In some embodiments of this utility model, combined with Figure 6 The cross-sectional area of ​​inlet 102 is smaller than that of outlet 103. Specifically, when the heat exchange medium enters the heat exchange channel 110, it is a low-temperature, low-pressure liquid (or a gas-liquid mixture) with a relatively high density and small volume. The smaller cross-sectional area of ​​inlet 102 is suitable for the high-density and small-volume flow of the liquid heat exchange medium. After absorbing heat in the heat exchange channel 110, the heat exchange medium completely evaporates into a low-temperature, low-pressure gas, resulting in a decrease in density and a significant increase in volume. Therefore, the larger cross-sectional area of ​​outlet 103 can accommodate the low-density and large-volume flow of the gaseous refrigerant, avoiding excessive flow resistance.

[0049] Combination Figure 1 In some embodiments of this utility model, the inlet 102 is provided with a first connector 13 and the outlet 103 is provided with a second connector 14. The first connector 13 and the second connector 14 can facilitate the connection of the pipe body at the inlet 102 and the outlet 103, which is beneficial to improving the sealing effect.

[0050] In some embodiments of this utility model, the first housing 10 is integrally formed and / or the second housing 20 is integrally formed, which facilitates manufacturing and assembly.

[0051] In some embodiments of this utility model, the first housing 10 is integrally formed and / or the second housing 20 is made of stainless steel, which can improve heat conduction, corrosion resistance, and durability of the refrigeration tank 100. In addition, stainless steel is easy to clean.

[0052] In some embodiments of this utility model, the connecting portion 12 and the protrusion 11 of the first housing 10 can be formed by compression molding.

[0053] Combination Figure 1 and Figure 7According to an embodiment of the present invention, the evaporator 1000 includes: the aforementioned refrigeration tank 100, a first tube 31 and a second tube 32. The first tube 31 is connected to the inlet 102 to deliver the heat exchange medium to the heat exchange channel 110, and the second tube 32 is connected to the outlet 103 to discharge the heat exchange medium after heat exchange, thereby realizing heat exchange.

[0054] According to the embodiment of the present utility model, by providing the aforementioned refrigeration tank 100 on the evaporator 1000, the heat exchange efficiency of the evaporator 1000 can be improved, the structure of the evaporator 1000 can be simplified, and the assembly of the evaporator 1000 can be simplified.

[0055] The refrigeration equipment according to the present invention includes: the aforementioned evaporator 1000, throttling element 200 and compressor (not shown in the figure), wherein the throttling element 200 is connected to the first tube 31 and the compressor is connected to the second tube 32. Specifically, the first tube 31 may be connected to the throttling element 200 so that low-temperature and low-pressure liquid refrigerant enters the heat exchange channel 110 therefrom, and the second tube 32 may be connected to the compressor so that the gaseous heat exchange medium is discharged to the compressor for circulation.

[0056] According to the refrigeration equipment of the present utility model embodiment, by providing the aforementioned evaporator 1000 on the refrigeration equipment, the heat exchange efficiency of the refrigeration equipment can be improved, and the structure of the refrigeration equipment can be simplified, and the assembly of the refrigeration equipment can be simplified.

[0057] In some embodiments of this utility model, the refrigeration equipment can be an ice maker or a smoothie maker, and the evaporator 1000 is used in the ice maker or smoothie maker.
