[0002] An evaporator is an important component in a refrigeration device and is a heat exchanger. A low-temperature condensed liquid passes through the evaporator and exchanges heat with the outside air, vaporizing and absorbing heat to achieve a refrigeration effect. Currently, the evaporators of most refrigeration devices (such as ice shavers) generally include an evaporator body and a coil. The evaporator body includes an inner and outer shell, and the coil is sleeved on the inner shell and contacts the outer shell wall. Condensed liquid is introduced into the coil, and the condensed liquid exchanges heat with the outside through the coil tube wall and the outer shell wall of the evaporator body to achieve a refrigeration effect. However, the heat of the above structure needs to be conducted through the coil tube wall and the outer shell wall of the evaporator body. Due to the large number of heat conduction media, the heat conduction efficiency is low, and the overall structure is relatively complex and the cost is high. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an evaporator and a refrigeration device, which can improve the heat conduction efficiency and the cold conduction performance of the evaporator, and have a simple overall structure and low production cost.

A condensation input pipe, a gas guide pipe, and a refrigerant area are arranged in the evaporator housing. The refrigerant area is arranged around the inner wall of the evaporator housing.

[0008] As an improvement of the above solution, one end of the refrigerant housing is provided with a limiting ring extending outward, and the limiting ring is sealingly connected to one end of the evaporator housing; the other end of the evaporator housing away from the limiting ring is provided with a supporting ring extending inward, and the supporting ring is sealingly connected to the other end of the refrigerant housing.

[0009] As an improvement of the above solution, an input pipe extending inward is provided on the input pipe orifice, and an output pipe extending inward is provided on the output pipe orifice. As an improvement of the above solution, the refrigerant area includes a convex member in a spiral shape, the convex member is sealingly connected to the inner wall of the evaporator housing, and a refrigerant channel is formed by enclosing between the inner cavity of the convex member and the evaporator housing.

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figures 1 to 3 shown, Figures 1 to 3 shows a schematic diagram of the structure of the first embodiment of the evaporator of the present utility model, including an evaporator housing 1. A condensation input pipe 2, a gas guide pipe 3 and a refrigerant area 4 are provided inside the evaporator housing 1; the refrigerant area 4 is arranged around the inner wall of the evaporator housing 1, and a refrigerant channel 5 is formed by enclosing between the refrigerant area 4 and the evaporator housing 1. The condensed liquid in the refrigerant channel 5 acts on the inner wall of the evaporator housing 1; the input end of the refrigerant channel 5 is connected to a condenser through the condensation input pipe 2, and the output end of the refrigerant channel 5 is connected to a compressor through the gas guide pipe 3. 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 housing 1, that is, it can perform heat exchange work with the outside air. The gas after the condensed liquid is vaporized will be discharged back to the compressor through the gas guide pipe 3. Among them, by arranging the refrigerant area 4 around the inner wall of the evaporator housing 1, the heat conduction area can be increased. The condensed liquid only needs to pass through the evaporator housing 1 (i.e., a single-layer heat conduction medium) to achieve heat conduction work with the outside. By reducing the heat conduction medium, the heat conduction efficiency can be effectively improved, thereby improving the heat conduction performance of the evaporator; and it can simplify the overall structure, save the assembly space and reduce the production cost.

[0025] Among them, the refrigerant area 4 includes a refrigerant housing 41 and a turbulator spiral fin 42. The refrigerant housing 41 is hermetically connected to the evaporator housing 1, so that a closed space is formed between the refrigerant housing 41 and the evaporator housing 1. The turbulator spiral fin 42 is located between the refrigerant housing 41 and the evaporator housing 1, and a refrigerant channel 5 is formed by enclosing the turbulator spiral fin 42, the refrigerant housing 41 and the evaporator housing 1. The spiral-structured refrigerant channel 5 can guide the flowing condensate liquid, fully vaporize the condensate liquid, improve the heat conduction efficiency, and further improve the cold conduction performance of the evaporator.

[0026] Preferably, the side wall material of the evaporator housing 1 is preferably metal, which has good heat conduction effect and can improve the cold conduction performance. However, the side wall material of the evaporator housing 1 is not limited to this, and other heat-conducting materials with good heat conduction effect can also be used.

[0027] Preferably, the material of the turbulator spiral fin 42 is preferably metal or plastic, but it is not limited thereto.

[0028] Furthermore, both ends of the refrigerant housing 41 are respectively provided with an input pipe orifice 411 and an output pipe orifice 412 communicating with the refrigerant channel 5. The condensate input pipe 2 is communicated with the refrigerant channel 5 through the input pipe orifice 411, so that the condenser can flow the condensate liquid into the refrigerant channel 5 through the condensate input pipe 2 and the input pipe orifice 411, so that the condensate liquid is gradually vaporized in the refrigerant channel 5 to realize the heat exchange work. The air guide pipe 3 is communicated with the refrigerant channel 5 through the output pipe orifice 412. When the refrigerant liquid in the refrigerant channel 5 is vaporized, the gas generated by the vaporization is discharged back to the compressor through the output pipe orifice 412 and the air guide pipe 3 to realize the cold conduction cycle work.

[0029] Furthermore, as Figures 4 to 5 shown, one end of the refrigerant housing 41 is provided with a limiting ring 413 extending outward, and the limiting ring 413 is hermetically abutted against one end of the evaporator housing 1. The other end of the evaporator housing 1 away from the limiting ring 413 is provided with a supporting ring 11 extending inward, and the supporting ring 11 is hermetically connected to the other end of the refrigerant housing 41, so as to fixedly support and limit the refrigerant housing 41 through the limiting ring 413 and the supporting ring 11, and form a closed space for storing condensate liquid between the refrigerant housing 41 and the evaporator housing 1, and at the same time prevent the condensate liquid from flowing out and affecting the cold conduction performance of the evaporator.

[0030] Preferably, as Figure 1 and Figure 4As shown, an input pipe 414 extending inward is provided on the input pipe orifice 411, so that the condensation input pipe 2 can be stably inserted into the input pipe 414 and welded, improving the connection stability and sealing performance. Correspondingly, an output pipe 415 extending inward is provided on the output pipe orifice 412, so that the air guide pipe 3 can be stably inserted into the output pipe 415 and welded, improving the connection stability and sealing performance.

[0031] As Figures 6 to 8 shown, Figures 6 to 8 shows a schematic structural view of the second embodiment of the evaporator of the present utility model. The difference between this embodiment and Figures 1 to 5 the first embodiment shown is that the refrigerant area 4 includes a spiral convex member 43, and the convex member 43 and the inner wall of the evaporator housing 1 are of an integrally stamped structure, so as to simplify the structure and improve the assembly efficiency. A refrigerant channel 5 is formed by enclosing between the inner cavity of the convex member 43 and the evaporator housing 1. The condensed liquid located in the refrigerant channel 5 can perform heat exchange work with the outside only through the evaporator housing 1. There is less heat-conducting medium, which can effectively improve the heat conduction efficiency, thereby improving the cold conduction performance of the evaporator; moreover, it can simplify the overall structure, save the assembly space and reduce the production cost. Secondly, the spiral refrigerant channel 5 can play a guiding role in the flowing condensed liquid, making the condensed liquid fully vaporize, improving the heat conduction efficiency, and further improving the cold conduction performance of the evaporator.

[0032] Wherein, input ports 431 and output ports 432 communicating with the refrigerant channel 5 are respectively provided at both ends of the convex member 43; the condensation input pipe 2 is inserted into the input port 431 and welded, so that the condenser provides condensed liquid for the refrigerant channel 5 through the condensation input pipe 2 and the input port 431, so that the condensed liquid is gradually vaporized in the refrigerant channel 5 to realize heat exchange work. The air guide pipe 3 communicates with the refrigerant channel 5 through the output port 432. When the refrigerant liquid in the refrigerant channel 5 is vaporized, the gas generated by the vaporization is discharged back to the compressor through the output port 432 and the air guide pipe 3 to realize the cold conduction cycle work.

[0033] Preferably, the cross section of the convex member 43 is in a regular shape. Among them, the regular shape means that at least one shape is arranged according to a certain rule. In this embodiment, as Figure 7 shown, the convex member 43 is preferably formed by sequentially arranging a plurality of semi-circular shapes, but not limited thereto, and may be formed by sequentially arranging other shapes (such as regular rectangles, squares or triangles; or irregular rectangles, squares or triangles); it may also be formed by sequentially arranging at least two shapes according to corresponding rules, such as alternately arranging two shapes or arranging them in sequence (such as arranging in squares first and then in rectangles, etc.).

[0034] Preferably, in other embodiments, the cross-section of the convex member 43 may also be in an irregular shape, where the irregular shape means that at least two shapes are arranged irregularly.

[0035] The present utility model also provides a refrigeration device, including a body, and the evaporator as described above is provided in the body. Among them, the refrigeration device includes but is not limited to a smoothie maker, a snow melter or an ice cream maker, etc.

[0036] In summary, the overall structure of the present utility model is simple, which can save the assembly space, reduce the production cost, and at the same time can reduce the heat conduction medium and improve the heat conduction efficiency; moreover, by guiding the condensed liquid, the condensed liquid can be fully vaporized, further improving the heat conduction efficiency, thereby greatly improving the cold conduction performance of the evaporator.

[0037] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
