[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 3 According to an embodiment of the present invention, the evaporator 1000 includes: a main body 100, a heat exchanger 20, and a heat insulation component. The main body 100 has a receiving cavity 101. The heat exchanger 20 and the heat insulation component are disposed in the receiving cavity 101, wherein the heat exchanger 20 is fixedly connected between the main body 100 and the heat insulation component. Specifically, both the heat insulation component and the heat exchanger 20 are disposed within the receiving cavity 101, and the heat exchanger 20 is disposed on the side closer to the surface of the main body 100, which allows it to be closer to the outside of the evaporator 1000, making it easier for the heat exchanger 20 to exchange heat with substances outside the main body 100. Inside the heat exchanger 20, the heat insulation component positions the heat exchanger 20 between the heat insulation component and the inside of the main body 100, which can reduce the energy loss of the heat exchanger 20, prevent cold energy from being transferred into the receiving cavity 101, and further improve the heat exchange effect of the heat exchanger 20. Furthermore, the insulation component can also fix the heat exchanger 20, eliminating the need for a separate fixing device for the evaporator 1000 and simplifying the structure of the heat exchanger 20. Therefore, by placing the insulation component and the heat exchanger 20 within the main body 100, and fixing the heat exchanger 20 between the insulation component and the main body 100, both the heat exchange efficiency and the structure of the evaporator 1000 can be improved.

[0032] According to the embodiment of the present utility model, the evaporator 1000 can be fixed between the main body 100 and the heat insulation component by setting a heat insulation component for fixing and heat insulation, which is conducive to improving the heat exchange effect, reducing the loss of cold energy, realizing the assembly and fixing of the heat exchanger 20, thereby simplifying the structure of the evaporator 1000.

[0033] Combination Figure 1 In some embodiments of this utility model, the main body 100 is cylindrical, and the heat exchanger 20 is a spirally extending tubular shape from top to bottom. Specifically, the cylindrical evaporator 1000 can reduce the space occupied by the evaporator 1000 and is easier to clean and maintain. When the evaporator 1000 is used in refrigeration equipment, it helps to improve the structural compactness of the refrigeration equipment. Combined with the spirally extending tubular heat exchanger 20, it can improve the uniformity of the distribution of the heat exchanger 20 within the main body 100, increase the contact area of ​​the heat exchanger 20, and improve the heat exchange effect. More specifically, the outer surface of the heat exchanger 20 abuts against the inner surface of the main body 100, and the outer surface of the heat insulation member abuts against the inner surface of the heat exchanger 20. In this way, the heat exchanger 20 is in surface-to-surface contact with the main body 100 and the insulation component, which helps to improve the fixing and support effect. In addition, the direct contact between the outer surface of the heat exchanger 20 and the inner surface of the main body 100 can improve the heat exchange efficiency, and the direct contact between the inner surface of the heat exchanger 20 and the outer surface of the insulation component can improve the temperature insulation effect of the insulation component, thereby reducing the loss of cold energy.

[0034] Furthermore, in some embodiments of this utility model, the main body 100 includes a shell 10 and a cover 13. The shell 10 has an open end, and the cover 13 seals the open end of the shell 10 to close the receiving cavity 101, thereby facilitating the opening and closing of the receiving cavity 101. During assembly, the heat exchanger 20 and the heat insulation component can be inserted into the shell 10 or the receiving cavity 101 from the open end of the shell 10, and then the open end of the shell 10 is sealed by the cover 13. The structure is simple and easy to construct.

[0035] Specifically, the insulation component includes a foam bag 31 and a foaming agent 32. The foaming agent 32 is disposed within the foam bag 31 and fills the receiving cavity 101. Specifically, the foaming agent 32 can form a foam layer with a low thermal conductivity, thereby preventing the temperature of the heat exchanger 20 from being conducted to the inside of the receiving cavity 101, reducing heat loss. The foaming agent 32 filling the receiving cavity 101 also improves the stability of the heat exchanger 20 within the receiving cavity 101, effectively fixing the heat exchanger 20 in place. Furthermore, the foaming agent 32 is lightweight, reducing the overall weight of the evaporator 1000, and is readily available, thus reducing manufacturing costs.

[0036] Furthermore, combining Figure 2In some embodiments of this utility model, the evaporator 1000 further includes a sealing member (not shown in the figure). The cover 13 is provided with a filling hole 103, which communicates with the internal space of the foam bag 31. The sealing member closes the filling hole 103 after the foaming agent 32 is filled into the receiving cavity 101. That is, during assembly, the heat exchanger 20 can be placed into the receiving cavity 101 first, and then the foam bag 31 can be placed in the receiving cavity 101 and located inside the heat exchanger 20. The cover 13 is then installed on the housing 10. The foaming agent 32 can be filled into the foam bag 31 in the receiving cavity 101 through the filling hole 103 on the cover 13, so that the foaming agent 32 fills the space inside the heat exchanger 20. When filling the foaming agent 32, the cover 13 can limit the filling space of the foaming agent 32, thereby improving the filling effect of the foaming agent 32 in the housing 10, and thus improving the fixing and heat insulation effect of the heat insulation member on the heat exchanger 20. After the foaming agent 32 is filled, the filling hole 103 can be sealed with a sealing member. The sealing member can be attached to the cover 13 by adhesive.

[0037] Optionally, the foaming agent 32 can be pre-foamed into a predetermined shape in the foaming bag 31 before the insulation component is placed entirely into the receiving cavity 101. Alternatively, when the user purchases the evaporator 1000, the foaming agent 32 and the evaporator 1000 are separate components. The foaming bag 31 is pre-placed in the receiving cavity 101. When assembling the evaporator 1000, the user can manually fill the foaming agent 32 into the foaming bag 31 through the filling hole 103, and then attach the sealing component to the filling hole 103.

[0038] Combination Figure 4 In some embodiments of this utility model, the evaporator 1000 further includes a sponge 70, which is disposed between the shell 10 and the cover 13. The sponge 70 can achieve pre-positioning between the shell 10 and the cover 13 when the foaming agent 32 is not filled, so that the cover 13 can be stably connected to the shell 10. When the foaming agent 32 is filled, the foaming agent 32 contacts the inside of the cover 13. The foaming agent 32 can have a certain viscosity. After the foaming agent 32 contacts the cover 13, it can improve the stability of the assembly of the cover 13.

[0039] Optionally, thermal grease can be applied to the inside of the housing 10 to form a thermal grease layer. The thermal grease improves the fit between the heat exchanger 20 and the inside of the housing 10, thereby increasing heat exchange efficiency. During assembly, the housing 10 can be placed on a fixture, and the thermal grease can be applied with a brush, rotating clockwise. The housing 10 can be made of stainless steel, which helps improve the structural stability of the housing 10 and enhances its temperature conduction.

[0040] Combination Figure 2In some embodiments of this utility model, the cover 13 is provided with a through hole 104, and the heat exchanger 20 has an inlet and an outlet for circulating the heat exchange medium. A portion of the heat exchanger 20 extends out from the through hole 104, so that the inlet and outlet of the heat exchanger 20 are located outside the main body 100, which facilitates the circulation of the heat exchange medium. Specifically, the heat exchanger 20 can be a spirally extended coil, with the inlet and outlet respectively located at both ends of the coil, and the end of the coil extending out of the main body 100 from the through hole 104. The coil includes a copper tube 21 and a capillary tube 22.

[0041] In some embodiments of this utility model, the heat exchanger 20 includes a first end, a second end, and a heat exchange section. The first end and the second end are connected to the heat exchange section. The first end is located at the upper end of the heat exchange section, and the second end is located at the lower end of the heat exchange section. The second end extends out of the housing 10. The heat exchange section is located inside the housing 10. The first end can be connected to a throttling element or a capillary tube 22, and the second end can be connected to the compressor of a refrigeration device.

[0042] Combination Figure 3 and Figure 9 In some embodiments of this utility model, the main body 100 is provided with a tube 40 penetrating the receiving cavity 101, and an installation channel 401 communicating with the outside of the main body 100 is constructed within the tube 40. The tube 40 can be used to install a rotating shaft 210. Specifically, the rotating shaft 210 can pass through the installation channel 401 and be installed on the evaporator 1000. Specifically, when the evaporator 1000 is used in a refrigeration device, the rotating shaft 210 can be installed on the evaporator 1000, and a stirring blade 220 can be connected to the rotating shaft 210. When the refrigeration device is used to cool the liquid, the stirring blade 220 rotates around the evaporator 1000, which can improve the uniformity of heat exchange and improve the heat exchange effect. When the refrigeration device needs to make shaved ice, the stirring blade 220 can rotate close to the outer periphery of the main body 100, thereby scraping off the ice layer adhering to the surface of the main body 100 after heat exchange, so that the refrigeration device can make shaved ice.

[0043] More specifically, combined Figure 9 The tube body 40 extends vertically, with its opposite ends connected to the housing 10 and the cover 13, respectively. The tube body 40 is hollow and communicates with the outside of the housing 10 and the cover 13. The rotating shaft 210 can pass through the mounting channel 401, allowing its opposite ends to extend out of the main body 100. One end of the rotating shaft 210 can be used to connect to the stirring blade 220, and the other end can be used to connect to the power device that drives the rotating shaft 210 to rotate.

[0044] Furthermore, combined Figure 3In some embodiments of this utility model, the cover 13 includes a plate 131 and a sleeve 132. The sleeve 132 extends toward the receiving cavity 101, and the tube 40 extends into the sleeve 132 and abuts against the plate 131. The plate 131 can close the receiving cavity 101, and the sleeve 132 can be used to connect the tube 40 and improve the stability after connection. Specifically, the sleeve 132 and the tube 40 can be an interference fit to improve the tightness and sealing of the connection. Alternatively, a sealing structure is provided between the sleeve 132 and the tube 40 to improve the tightness and sealing of the connection.

[0045] Furthermore, combining Figure 5 In some embodiments of this utility model, the end of the shell 10 opposite to the cover 13 is provided with a first opening 110, which connects to the tube 40, thereby allowing the installation channel 401 to communicate with the outside of the main body 100. To achieve a seal between the first opening 110 and the tube 40, the evaporator 1000 also includes a sealing element 50. The sealing element 50 has a through hole 501, which connects to the tube 40, and is located between the first opening 110 and the tube 40. Thus, the sealing element 50 can achieve a seal between the tube 40 and the first opening 110, and the through hole 501 of the sealing element 50 can connect the installation channel 401 to the outside of the main body 100. When the rotating shaft 210 passes through the through hole 501, the sealing element 50 can also achieve a seal around the rotating shaft 210, thereby preventing external media from entering the installation channel 401 and improving operational reliability.

[0046] Specifically, in combination Figure 1 and Figure 3 The shell 10 includes a top plate 11 and a side plate 12. The top plate 11 is connected to the side plate 12 and is opposite to the cover 13. The first opening 110 is provided on the top plate 11, so that the installation channel 401 can penetrate the main body 100 in the vertical direction. After the rotating shaft 210 is installed on the tube 40, the stirring blade 220, which is connected to the rotating shaft 210, can be arranged around the side plate 12 to improve the stirring effect or the ice scraping effect.

[0047] More specifically, combined Figure 3 In some embodiments of this utility model, the sealing element 50 includes a sealing seat 51, a sealing cap 52, a baffle 53, and a sealing ring 54; the sealing seat 51 is disposed inside the housing 10, the lower end of the sealing seat 51 is connected to the pipe body 40, the upper end of the sealing seat 51 is provided with a groove 510, the sealing cap 52 is disposed outside the housing 10 and a part of the sealing cap 52 extends into the groove 510; the baffle 53 is disposed between the housing 10 and the sealing cap 52. Figure 8The sealing ring 54 includes a body portion 540, which extends vertically and passes through the housing 10. A first baffle 541 and a second baffle 542 are provided on the outer periphery of the body portion 540. The first baffle 541 is sandwiched between the sealing seat 51 and the sealing cover 52, and the second baffle 542 covers the sealing cover 52. The sealing seat 51, sealing cover 52, baffle 53, and sealing ring 54 are all constructed in a ring shape. After the sealing seat 51, sealing cover 52, baffle 53, and sealing ring 54 are connected, a through hole 501 is formed on their inner sides. The through hole 501 can connect to the installation channel 401 inside the tube body 40, allowing the rotating shaft 210 to pass through the evaporator 1000 and be sealed to it.

[0048] Specifically, the sealing seat 51 is located inside the housing 10, and the sealing cover 52 is located outside the housing 10. By inserting the sealing cover 52 into the groove 510 of the sealing seat 51, a seal can be formed at the first opening 110 of the housing 10. The tight fit between the sealing seat 51 and the sealing cover 52 can improve the sealing effect. To further improve the sealing effect, a baffle 53 is also provided between the sealing cover 52 and the housing 10. The baffle 53 is located between the sealing cover 52 and the housing 10, which improves the tightness of the seal between the sealing cover 52 and the housing 10, thereby increasing the sealing effect at the first opening 110. There is also a sealing ring 54 between the sealing seat 51 and the sealing cover 52. The sealing ring 54 is connected to the inner side of the sealing seat 51. It can not only achieve a seal at the fit between the sealing seat 51 and the sealing cover 52, but also improve the structural compactness of the sealing element 50 at the through hole 501, thereby improving the sealing effect after the rotating shaft 210 extends into the through hole 501 and preventing external media from entering the evaporator 1000 or the refrigeration equipment.

[0049] Combination Figure 6 The sealing seat 51 includes a connecting portion and a rod portion 511. A first connecting portion 512 is coaxially connected to the rod portion 511 along the axial direction, and the circumferential dimension of the first connecting portion 512 is larger than that of the rod portion 511. The first connecting portion 512 forms a groove 510, and a stepped structure is formed between the first connecting portion 512 and the rod portion 511. During assembly, the rod portion 511 extends into the tube body 40, and the end of the tube body 40 abuts against the stepped structure. The first connecting portion 512 abuts against the inner side of the housing 10, thereby achieving a sealed connection between the sealing seat 51 and the tube body 40 at the first opening 110 of the housing 10. The inner circumference of the first connecting portion 512 has a plurality of circumferentially spaced positioning protrusions 5121. The positioning protrusions 5121 can play a positioning role when the rotating shaft 210 extends into the sealing seat 51, improving the fixing and support effect of the rotating shaft 210, thereby improving the stability of the rotating shaft 210 after assembly or during operation.

[0050] Combination Figure 5 and Figure 7The sealing cover 52 includes a second connecting portion 521 and a blocking portion 522, which are coaxially connected along the axial direction. The circumferential dimension of the second connecting portion 521 is smaller than that of the blocking portion 522. The second blocking portion 522 extends into the groove 510 of the first blocking portion 522, which can improve the tightness of the fit between the sealing cover 52 and the sealing seat 51 and improve the sealing effect. The blocking portion 522 covers the outer surface of the housing 10, which can improve the sealing effect of the sealing cover 52 at the first opening 110 of the housing 10. More specifically, in combination with Figure 4 The first connecting part 512 is provided with a first mounting hole 5120, and the second connecting part 521 is provided with a second mounting hole 5210. The first mounting hole 5120 and the second mounting hole 5210 are axially opposite each other. The first mounting hole 5120 and the second mounting hole 5210 can be fixed by screws 55, thereby realizing a fixed connection between the sealing seat 51 and the sealing cover 52.

[0051] Combination Figure 3 The baffle 53 is sandwiched between the first connecting part 512 and the second connecting part 521 and abuts against the blocking part 522 in the axial or vertical direction. The body part 540 of the sealing ring 54 passes through the inner side of the first connecting part 512 and the second connecting part 521. The body part 540 is provided with a first baffle 541 and a second baffle 542 that protrude radially. The first baffle 541 and the second baffle 542 are arranged axially at intervals. The first baffle 541 is sandwiched between the first connecting part 512 and the second connecting part 521 and abuts against the blocking part 522 to improve the connection between the sealing seat 51 and the sealing cover 52. The second baffle 542 covers the blocking part 522, and a part of the blocking part 522 extends into the space between the first baffle 541 and the second baffle 542.

[0052] Combination Figure 1 and Figure 4 In some embodiments of this utility model, the evaporator 1000 further includes a temperature sensing element 61. The temperature sensing element 61 is connected to the housing 10 and the temperature sensing probe of the temperature sensing element 61 extends into the receiving cavity 101. It can detect the temperature inside the receiving cavity 101, thereby judging the working condition or temperature of the heat exchanger 20 based on the measured temperature. Thus, the operation of the heat exchanger 20 can be controlled by the temperature sensing element 61, which can ensure the cooling effect.

[0053] Furthermore, the temperature sensing probe of the temperature sensing element 61 is located inside the heat exchanger 20, which can improve the accuracy of detection, thereby better judging the working condition of the heat exchanger 20 and improving the precision of temperature control. Combined with... Figure 4 The housing 10 or the top plate 11 of the housing 10 is provided with a second opening 120. The temperature measuring element 61 extends into the receiving cavity 101 from the second opening 120.
