[0039] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] First embodiment: Figures 1-8 As shown, an evaporator and a refrigeration device are provided. The evaporator includes an evaporator shell 1 and a refrigerant shell 41. A heat exchanger 6 is provided between the evaporator shell 1 and the refrigerant shell 41. The heat exchanger 6 includes a spoiler rib 61 on the side close to the evaporator shell 1, and the side of the heat exchanger 6 away from the spoiler rib 61 is arranged on the refrigerant shell 41. A refrigerant channel 5 for the flow of condensed liquid is formed between the heat exchanger 6 and the evaporator shell 1 through the spoiler rib 61.

[0041] Specifically, during operation, the condenser transports the condensed liquid to the refrigerant channel 5 through the condensation input pipe 2. The condensed liquid flowing into the refrigerant channel 5 can directly absorb heat from the outside through the evaporator shell 1, and can realize heat exchange with the outside air. The gas after the condensed liquid is vaporized will be discharged back to the compressor through the air duct 3; wherein, the outer surface of the side wall of the heat exchanger 6 is provided with a spoiler rib 61, which not only increases the heat exchange area, but also increases the flow speed and mixing degree of the condensed liquid in the refrigerant channel 5 by generating a spoiler effect, thereby enhancing the heat exchange effect. The condensed liquid only needs to pass through the evaporator shell 1 (that is, a single layer of heat-conducting medium) to realize heat exchange with the outside world. By reducing the heat-conducting medium, the heat conduction efficiency can be effectively improved, thereby improving the cooling performance of the evaporator; and it can simplify the overall structure, save assembly space, and reduce production costs.

[0042] Preferably, the shell wall of the evaporator shell 1 is made of metal, which has good heat conduction effect and can improve the cooling performance. However, the shell wall material of the evaporator shell 1 is not limited to this, and can also be other heat conductive materials with good heat conduction effect.

[0043] Preferably, the heat exchange element 6 is made of silicone or plastic, but is not limited thereto.

[0044] Further, if Figure 5 As shown, a heat exchange area is formed between one side of the heat exchange element 6 and the evaporator shell 1 , and a heat insulation area is formed between the side of the heat exchange element 6 away from the spoiler rib 61 and the refrigerant shell 41 .

[0045] Specifically, a heat exchange zone is formed between one side of the spoiler rib 61 of the heat exchange element 6 and the evaporator shell 1, ensuring that the condensed liquid can directly exchange heat with the outside world, thereby improving the heat conduction efficiency; a heat insulation zone is formed between the side of the heat exchange element 6 away from the spoiler rib 61 and the refrigerant shell 41, reducing unnecessary heat conduction, avoiding the heat of the condensed liquid from being lost to the non-heat exchange area, and further improving the cooling effect. By distinguishing between the heat exchange zone and the heat insulation zone, the thermal efficiency of the system is further improved, allowing the evaporator to operate in a more efficient state.

[0046] Further, if Figure 2 As shown, the heat exchange element 6 includes a heat insulating body 62 , which is sleeved or embedded in the refrigerant shell 41 , and the spoiler ribs 61 are protruded from the side wall of the heat insulating body 62 and abut against the evaporator shell 1 .

[0047] Specifically, the insulation body 62 is sleeved on the refrigerant shell 41, or the insulation body 62 is embedded in the refrigerant shell 41. Through the insulation body 62, the heat lost to the outside by the condensed liquid through the refrigerant shell 41 is effectively reduced, and the structure is made more stable, reducing the displacement between components.

[0048] Further, if Figure 3 、 Figure 7 and Figure 8 As shown, the spoiler rib 61 and the heat exchange element 6 are an integrated structure or a split structure.

[0049] Specifically, when the spoiler rib 61 and the heat exchanger 6 are an integrated structure, they are formed as one piece by injection molding or stamping, which is beneficial to reducing production costs and improving production efficiency; when the spoiler rib 61 and the heat exchanger 6 are a split structure, the spoiler rib 61 and the heat exchanger 6 are processed and manufactured separately and then connected together by welding, bonding or clamping to facilitate subsequent maintenance and replacement work, because when one of the components is damaged, only the component needs to be replaced without replacing the entire evaporator.

[0050] Further, if Figure 3 、 Figure 7 and Figure 8 As shown, the spoiler ribs 61 are spirally coiled on the heat exchanger 6; there is at least one spoiler rib 61, each spoiler rib 61 is arranged at intervals along the length direction of the heat exchanger 6, and the spiral direction of each spoiler rib 61 is consistent; the refrigerant shell 41, the heat exchanger 6 and all the spoiler ribs 61 form more than one refrigerant channel 5; all the refrigerant channels 5 are arranged in parallel or overlapped, and all the refrigerant channels 5 are separated by the spoiler ribs 61.

[0051] Further, if Figure 7 and Figure 8 As shown, the width of the refrigerant channel 5 is equal to the pitch between two adjacent spoiler ribs 61 .

[0052] Specifically, the spoiler ribs 61 are arranged at intervals along the length of the heat exchanger 6. Such a layout helps to evenly distribute the spoiler effect over the entire length of the heat exchanger 6, so that the condensed liquid can be continuously disturbed during the flow process, thereby increasing the uniformity and efficiency of heat exchange; the spoiler ribs 61 have the same spiral direction, so that the condensed liquid will form a consistent flow trend when flowing through these spoiler ribs 61, reducing the eddy currents and resistance that may be caused by inconsistent directions, and further improving the flow speed and heat exchange efficiency.

[0053] The parallel arrangement of all refrigerant channels 5 means that multiple refrigerant channels 5 are formed by surrounding them with multiple spoiler ribs 61. The multiple refrigerant channels 5 are independent of each other, which helps to increase the total flow area of the condensed liquid, thereby improving the capacity and efficiency of the heat exchange; through the interval arrangement of the spoiler ribs 61, the condensed liquid can form independent flow paths when flowing through different refrigerant channels 5, avoiding mixing and interference of the fluids, and ensuring the stability and efficiency of the heat exchange process.

[0054] The overlapping arrangement of all the refrigerant channels 5 means that one spoiler rib 61 surrounds and forms one refrigerant channel 5 .

[0055] When the width of the refrigerant channel 5 is equal to the pitch between two adjacent spoiler ribs 61, the condensed liquid can fully utilize the space between the spoiler ribs 61 for heat exchange during the flow process, without increasing the flow resistance or insufficient heat exchange due to the channel being too narrow.

[0056] Further, if Figure 5 As shown, the spoiler rib 61 includes one or more wave crests 611 arranged axially and spaced apart from each other along the heat exchange element 6 , and the wave crests 611 are in sealing contact with the inner wall of the evaporator shell 1 .

[0057] Specifically, each wave peak 611 is tightly and sealed against the inner wall of the evaporator shell 1, ensuring that the flow path of the condensed liquid in the refrigerant channel 5 is limited, reducing the flow resistance, increasing the flow speed, thereby improving the heat exchange efficiency, and ensuring the airtightness of the refrigerant channel 5, preventing the condensed liquid from leaking during the flow process.

[0058] Further, if Figure 2 、 Figure 4 and Figure 6 As shown, the refrigerant shell 41 and the evaporator shell 1 are nested, and a sealed space for installing the heat exchanger 6 is provided between the refrigerant shell 41 and the evaporator shell 1. The heat exchanger 6 is sleeved on the refrigerant shell 41. The central axes of the refrigerant shell 41, the evaporator shell 1 and the heat exchanger 6 are coaxially arranged, and the refrigerant shell 41 and the evaporator shell 1 are sealed at the same end connection.

[0059] Specifically, the refrigerant housing 41 and the evaporator housing 1 are nested, which makes the structure of the entire evaporator more compact, reduces the volume of the equipment, and facilitates the integration and installation of the equipment.

[0060] A sealed space for installing the heat exchange element 6 is provided between the refrigerant shell 41 and the evaporator shell 1, ensuring that the heat exchange element 6 can be firmly installed inside the evaporator and forming a good sealing relationship between the refrigerant shell 41 and the evaporator shell 1 to prevent leakage of condensed liquid; the coaxially arranged refrigerant shell 41, evaporator shell 1 and heat exchange element 6 help to reduce the flow resistance and thermal stress caused by axial deviation, thereby improving the overall performance of the evaporator.

[0061] The refrigerant housing 41 and the evaporator housing 1 are sealed at the connection point at the same end, which prevents the leakage of heat and condensed liquid and further improves the heat exchange efficiency.

[0062] Further, if Figure 2 As shown, one end portion of the evaporator shell 1 is provided with an evaporator shell opening 11, and one end portion of the refrigerant shell 41 is provided with a refrigerant shell opening 414 corresponding to the evaporator shell opening 11. The opening on the more outward end of the evaporator shell opening 11 and the refrigerant shell opening 414 is larger than the opening on the more inward end, and in the orthographic projection in the direction of the central axis of the evaporator, the edge of the more inward opening is located inside the edge of the more outward opening, and the edge of the evaporator shell opening 11 and the edge of the refrigerant shell opening 414 are sealed and fixedly connected by welding.

[0063] Specifically, the opening on the outward end is larger than the opening on the inward end, ensuring closer contact between the edges during welding. This design not only enhances weld strength but also ensures a tight seal at the weld, effectively preventing refrigerant leakage. Furthermore, welding provides a sealed, secure connection between the two, providing a high-strength and high-tightness connection, further improving the sealing performance and stability of the evaporator.

[0064] It should be pointed out that a sealing material or sealing structure may be provided between the evaporator shell opening 11 and the refrigerant shell opening 414 for sealing. In this way, when the refrigerant shell 41 is fully installed on the evaporator shell 1, a reliable sealing connection will be formed between the two to prevent the condensed liquid from leaking during the flow process.

[0065] Further, if Figure 6 As shown, a flange 12 extending outward is provided on the other end of the evaporator shell 1, and a flange 413 extending outward is provided on the other end of the refrigerant shell 41. The flange 12 and the flange 413 are fixedly connected together by welding or bonding.

[0066] Specifically, in order to ensure the firmness and sealing of the connection, the flange 12 and the flange 413 are sealed and fixed by welding or bonding, which ensures the firmness and sealing of the connection part and prevents leakage of the refrigerant liquid.

[0067] Further, if Figure 3 、 Figure 7 and Figure 8 As shown, a condensation input pipe 2 and an air duct 3 are provided in the refrigerant housing 41 , the input end of the refrigerant channel 5 is connected to the condenser through the condensation input pipe 2 , and the output end of the refrigerant channel 5 is connected to the compressor through the air duct 3 .

[0068] Specifically, the condensation input pipe 2 is a channel connecting the condenser and the input end of the refrigerant channel 5; the condensed liquid that has been preliminarily cooled in the condenser is transported to the refrigerant channel 5 to provide the necessary cooling capacity for the subsequent evaporation process. Through the condensation input pipe 2, the condensed liquid can enter the refrigerant channel 5 smoothly and continuously, ensuring the smooth progress of the heat exchange process; in the refrigerant channel 5, the condensed liquid is gradually evaporated into a gaseous refrigerant through the heating action of the heat exchange element 6, and releases a large amount of heat. These gaseous refrigerants are then transported to the compressor through the air duct 3 for further compression and recycling.

[0069] Further, if Figure 3 、 Figure 7 and Figure 8 As shown, the refrigerant housing 41 is provided with an input pipe opening 411 and an output pipe opening 412 at both ends thereof, which are in one-to-one communication with the refrigerant channels 5 .

[0070] Specifically, the input pipe port 411 is located at one end of the refrigerant shell 41, and allows the condensed liquid to enter the entrance of the refrigerant channel 5, ensuring that the condensed liquid can accurately enter the corresponding channel for heat exchange; the output pipe port 412 is located at the other end of the refrigerant shell 41, corresponding to the input pipe port 411. When the refrigerant liquid in the refrigerant channel 5 is vaporized, the gas generated by its vaporization is discharged back to the compressor through the output pipe port 412 and the air guide pipe 3, realizing the cooling cycle.

[0071] Further, if Figure 3 、 Figure 7 and Figure 8 As shown, the condensation input pipe 2 is connected to the refrigerant channel 5 through the input pipe opening 411, and the air guide pipe 3 is connected to the refrigerant channel 5 through the output pipe opening 412.

[0072] Specifically, the condensation input pipe 2 is connected to the refrigerant channel 5 through the input pipe port 411 , and the condensed liquid is transported from the condenser to the input pipe port 411 through the condensation input pipe 2 and enters the refrigerant channel 5 .

[0073] Further, if Figure 5 、 Figure 7 and Figure 8 As shown, when the side of the heat exchange element 6 away from the spoiler rib 61 is located on the refrigerant housing 41, the spoiler rib 61 extends toward the evaporator housing 1 to form a refrigerant channel 5 for heat exchange between the condensed liquid and the evaporator housing 1 and the outside air.

[0074] Specifically, the refrigerant channel 5 formed by the spoiler rib 61 extending toward the evaporator shell 1 enables the condensed liquid to directly exchange heat with the evaporator shell 1. The condensed liquid exchanges heat with the outside air through the refrigerant channel 5 and the evaporator shell 1, absorbs heat and vaporizes; the vaporized gas is discharged back to the compressor through the air duct, completing a refrigeration cycle.

[0075] The utility model also provides a refrigeration device, comprising a body, wherein the evaporator is arranged in the body. The refrigeration device includes but is not limited to a snow melter or a smoothie machine.

[0076] The second embodiment, as Figures 9-12 As shown, the present evaporator and refrigeration equipment differ from the first embodiment in that the heat exchange element 6 is arranged on the evaporator shell 1 on a side away from the spoiler rib 61, and the heat exchange element 6 forms an internal and external refrigerant channel 5 for the flow of condensed liquid between the spoiler rib 61 and the refrigerant shell 41.

[0077] like Figure 9 and Figure 11 As shown, when the side of the heat exchange element 6 away from the spoiler rib 61 is located on the evaporator shell 1, the spoiler rib 61 extends toward the refrigerant shell 41 to form a refrigerant channel 5 for heat exchange between the condensed liquid and the refrigerant shell 41 and the outside air.

[0078] A heat exchange area is formed between one side of the heat exchange element 6 with the spoiler rib 61 and the refrigerant shell 41 , and a heat insulation area is formed between the side of the heat exchange element 6 away from the spoiler rib 61 and the evaporator shell 1 .

[0079] When the above-mentioned evaporator is applied to a refrigeration device, the refrigeration device includes but is not limited to an ice maker or an ice cream maker.

[0080] Specifically, a heat exchange zone is formed between one side of the spoiler rib 61 of the heat exchange element 6 and the refrigerant shell 41, ensuring that the condensed liquid can directly exchange heat with the outside world, thereby improving the heat conduction efficiency; a heat insulation zone is formed between the side of the heat exchange element 6 away from the spoiler rib 61 and the evaporator shell 1, reducing unnecessary heat conduction and preventing the heat of the condensed liquid from being lost to the non-heat exchange area, thereby further improving the cooling effect. By distinguishing the heat exchange zone from the heat insulation zone, the thermal efficiency of the system is further improved, allowing the evaporator to operate at a more efficient state; the condensed liquid exchanges heat in the heat exchange zone between the heat exchange element 6 and the refrigerant shell 41, absorbs heat and vaporizes;

[0081] The spoiler ribs 61 extend toward the refrigerant shell 41 to form a refrigerant channel 5, which enables the condensed liquid to directly exchange heat with the refrigerant shell 41. The condensed liquid exchanges heat with the outside air through the refrigerant channel 5 and the refrigerant shell 41, absorbs heat and vaporizes; the vaporized gas is discharged back to the compressor through the air duct, completing a refrigeration cycle.

[0082] Other undescribed parts are the same as those in the first embodiment.

[0083] The third embodiment, as Figure 13 As shown, the present evaporator and refrigeration equipment are different from the first embodiment in that: the refrigerant shell 41 is provided with a plurality of middle input pipe openings 416 along the flow direction of the refrigerant channel 5, and the plurality of middle input pipe openings 416 are evenly spaced on the refrigerant shell 41 and are located between the input pipe opening 411 and the output pipe opening 412, and the middle input pipe opening 416 is connected to the condenser through the corresponding condensation input pipe 2.

[0084] Specifically, by providing multiple central input nozzles 416 along the flow direction of the refrigerant channel 5 in the refrigerant housing 41, the condensed liquid can enter the refrigerant channel 5 evenly at multiple points, thereby improving the uniformity of the fluid flow. The evenly spaced arrangement of the multiple central input nozzles 416 ensures the uniform distribution of the condensed liquid in the refrigerant channel 5, reduces the temperature gradient of the fluid during flow, and enhances the heat exchange efficiency. When the evaporator is operating, the condensed liquid from the condenser flows synchronously through the input nozzle 411 and the multiple central input nozzles 416 into different positions of the refrigerant channel 5 and acts on the evaporator housing 1, so that the low-temperature condensed liquid can exchange heat more quickly at different positions of the evaporator, accelerating the circulation and heat exchange rate of the overall condensed liquid, thereby improving the cooling efficiency of the evaporator.

[0085] Other undescribed parts are the same as those in the first embodiment.

[0086] The fourth embodiment, as Figure 14 As shown, this evaporator and refrigeration device differ from the first embodiment in that three baffle ribs 61 are provided on the heat exchange element 6. Three refrigerant channels 5 are formed between the refrigerant housing 41, the heat exchange element 6, and the three baffle ribs 61. The three refrigerant channels 5 are arranged in parallel and separated by the baffle ribs 61. The provision of three independent refrigerant channels 5 allows the condensed liquid to flow in synchronously for heat exchange, effectively improving the heat exchange efficiency and effect of the condensed liquid, thereby enhancing the cooling efficiency of the evaporator.

[0087] Other undescribed parts are the same as those in the first embodiment.
