Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a coil type evaporator. Background Art

[0002] Popsicles are one of the most familiar cold foods. They are usually low in cost and are made by mixing and freezing water, juice, sugar, milk, etc. They are especially thirst-quenching and heat-relieving in summer. With the improvement of living standards and the enhancement of food safety awareness, popsicles purchased directly on the market contain a lot of additives. Therefore, people prefer to make popsicles, ice cream and other snacks at home.

[0003] A popsicle machine is an appliance that can be used to make popsicles at home. The evaporator is one of the key components. It absorbs heat to lower the temperature of the surrounding environment, thereby achieving a cooling effect. However, traditional popsicle machines generally place the popsicle molds in a refrigerant first, then the compressor cools the refrigerant through the evaporator, and then cools the popsicle molds through the refrigerant. This results in a low heat transfer coefficient, slow ice formation, and high energy consumption. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a coil-type evaporator.

[0005] The purpose of the utility model can be achieved through the following technical scheme: a coil evaporator, including a molded body, on which is provided a molded cavity with one end open; an evaporating tube, which is wound around the outer wall of the molded body; a shell, which is sleeved on the outside of the evaporating tube; and a gap between the shell and the outer wall of the molded body is filled with an insulation layer.

[0006] Preferably, the cross-section of the molding cavity is an inverted trapezoidal structure.

[0007] Preferably, both ends and the bottom of the inner wall of the molding cavity are arc-shaped structures.

[0008] Preferably, at least two molding cavities are arranged side by side on the molding body.

[0009] Preferably, the thermal insulation layer is a foam material.

[0010] The beneficial effect of the utility model is that the utility model winds the evaporator tube around the outer wall of the molding body so that when the refrigerant vaporizes and absorbs heat in the evaporator tube, it takes away the heat in the molding cavity, causing the material in the molding cavity to freeze into ice, thereby greatly improving the heat exchange efficiency, reducing the freezing time, and effectively reducing energy consumption.

[0016] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0017] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0018] The following will be combined with specific embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0019] See also Figures 1 to 3As shown, the structure of the utility model is: a coil evaporator, including a molding body 1, on which is provided a molding cavity 101 with an opening at one end; an evaporating tube 2, which is wound around the outer wall of the molding body 1; a shell 3, which is sleeved on the outer side of the evaporating tube 2; the gap between the shell 3 and the outer wall of the molding body 1 is filled with a thermal insulation layer 4, specifically, one end of the evaporating tube 2 passes through the side wall of the shell 3, and is connected with the capillary tube and the condenser in the refrigeration system, and the other end of the evaporating tube 2 passes through the bottom of the shell 3 and is connected with the compressor in the refrigeration system, after the refrigerant is compressed by the compressor, it is then cooled by the condenser, and enters the evaporating tube 2 after throttling and reducing the pressure by the capillary tube, the refrigerant vaporizes and absorbs heat in the evaporating tube 2, and takes away the heat from the molding body 1, causing the material in the molding cavity 101 to freeze into ice, thereby improving the heat exchange efficiency, reducing the freezing time, and effectively reducing energy consumption.

[0020] like Figure 3 As shown, the cross section of the molding cavity 101 is an inverted trapezoidal structure. Specifically, the inverted trapezoidal structure, which is wide at the top and narrow at the bottom, facilitates the removal of the frozen popsicle from the molding cavity 101 .

[0021] like Figure 3 As shown, both ends and the bottom of the inner wall of the molding cavity 101 are arc-shaped structures. Specifically, the arc-shaped inner wall of the molding cavity 101 is convenient for cleaning and prevents sanitary dead corners in the molding cavity 101. On the other hand, it is conducive to ensuring the complete removal of the popsicle.

[0022] like Figure 1 , Figure 3 As shown, at least two forming cavities 101 are arranged side by side on the forming body 1. Specifically, multiple forming cavities 101 can be formed at one time, which is beneficial to improving the efficiency of popsicle forming.

[0023] Furthermore, the thermal insulation layer 4 is a foaming material, specifically, the foaming material is polyurethane, which has a low thermal conductivity and excellent thermal insulation performance, thereby preventing external heat from entering the molding cavity 101 and the evaporation tube 2 .

[0024] During specific use, one end of the evaporator tube 2 passes through the side wall of the shell 3 and is connected to the capillary tube and the condenser in the refrigeration system. The other end of the evaporator tube 2 passes through the bottom of the shell 3 and is connected to the compressor in the refrigeration system. The refrigerant is compressed by the compressor and then cooled by the condenser. After throttling and reducing the pressure through the capillary tube, it enters the evaporator tube 2. The refrigerant vaporizes and absorbs heat in the evaporator tube 2, taking away the heat in the molding body 1, causing the material in the molding cavity 101 to freeze into ice, thereby improving the heat exchange efficiency, reducing the freezing time, and effectively reducing energy consumption. By filling the gap between the shell 3 and the outer wall of the molding body 1 with foaming material, external heat is prevented from entering the molding cavity 101 and the evaporator tube 2.

[0025] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
