[0018] Figure 1 It is a structural diagram of an embodiment of the inflation type evaporator of the utility model. DETAILED DESCRIPTION

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0020] The refrigeration device of the embodiment of the utility model includes an inner tank, which has a refrigeration chamber for refrigeration, and an inflation type evaporator is provided at the side wall of the inner tank; illustratively, the inflation type evaporator is arranged on the outer side of the rear side wall of the inner tank, and in other embodiments, it can also be arranged at other positions. The installation position of the inflation type evaporator is not limited here and will not be expanded.

[0021] like Figure 1 As shown, the inflation evaporator includes an evaporation plate 10 and a refrigeration pipeline 20 formed on the evaporation plate 10, and the refrigeration pipeline 20 is formed by inflation. The refrigeration pipeline 20 includes a capillary tube 21, a connecting tube 22, an evaporation tube 23, an air outlet pipe 24 and two evaporation areas 25; the two evaporation areas 25 are respectively a first evaporation area 25a and a second evaporation area 25b, wherein the capillary tube 21 is connected to the inlet of the first evaporation area 25a through the connecting tube 22, the outlet of the first evaporation area 25a is connected to the inlet of the second evaporation area 25b through the evaporation tube 23, and the outlet of the second evaporation area 25b is connected to the air outlet pipe 24 to form a cycle.

[0022] Furthermore, a fastener 26 is preferably provided at the connection between the capillary tube 21 and the connecting tube 22, and the fastener 26 is used to fix the capillary tube 21 to prevent the capillary tube 21 from shaking and escaping from the copper tube, and also to reduce noise. The upstream side 21a of the capillary tube 21 is preferably wound around the outlet pipe 24, and the capillary tube 21 is away from the head end 21b of the evaporation plate 10. Figure 1 The self-winding arrangement is shown in the manner shown, and the winding diameter is preferably a circle of 50mm-80mm. The number of winding turns is determined according to the actual length, which is not limited here.

[0023] Please continue reading Figure 1 The evaporation plate 10 is provided with a through hole 11 for installing a fan, and the first evaporation area 25a and the second evaporation area 25b are located on opposite sides of the through hole 11 in the lateral direction. The evaporation area 25 is provided with a plurality of first flow reducing portions 251, and the plurality of first flow reducing portions 251 form a mesh channel with multi-directional flow paths inside the evaporation area 25.

[0024] In the embodiment, the multi-directional flow of the refrigerant when flowing through the evaporation area 25 can reduce its flow speed, reduce the impact of the refrigerant and facilitate the smooth flow of the refrigerant; at the same time, the first flow reducing portion 251 also increases the effective area of ​​the evaporation area 25, which is beneficial to heat exchange and improves the refrigeration effect. Preferably, the first flow reducing portion 251 is provided on both sides of the evaporation plate 10, wherein there is a gap between the two corresponding first flow reducing portions 251 on the front and back sides of the evaporation plate 10, and the refrigerant can pass through the gap.

[0025] The evaporation area 25 is preferably square, and a plurality of first flow reducing portions 251 are arranged in an array. The first flow reducing portion 251 is preferably a groove-shaped flow reducing portion formed by a depression along the surface of the evaporation plate 10. The shape of the groove-shaped flow reducing portion can be circular, square, polygonal, or other shapes; preferably a circle with smooth edges, which can be more conducive to the smooth flow of the refrigerant.

[0026] The capillary tube 21 and the connecting tube 22 are both located above the through hole 11 and the two evaporation zones 25 in the longitudinal direction; wherein, the connecting tube 22 includes a transition tube 221, which is in the shape of a trumpet with a small inlet end and a large outlet end. The refrigerant is injected into the connecting tube 22 through the capillary tube 21, and the flow velocity is reduced. After passing through the transition tube 221, the injection noise can be fully reduced, thereby achieving the purpose of shock absorption and noise reduction.

[0027] The evaporation tube 23 is located below the through hole 11 and the two evaporation zones 25 in the longitudinal direction; wherein, a plurality of second flow reducing portions 231 are provided on at least a portion of the tube section of the evaporation tube 23, and the second flow reducing portions 231 are at least used to increase the area of ​​the evaporation tube 23, where the area is specifically the area of ​​the evaporation tube 23 in contact with the outside for heat exchange. Specifically, the second flow reducing portion 231 has the same structure as the first flow reducing portion 251, and will not be described in detail. In other embodiments, the structure of the second flow reducing portion 231 may also be provided as required, and will not be described in detail.

[0028] Furthermore, at least some sections of the evaporation tube 23 are adjacent to each other and a closed area 23a is formed inside the adjacent sections. A plurality of perforations 232 are provided in the closed area 23a. The main purpose of providing the perforations 232 is to cooperate with the through hole 11, that is, during operation, under the action of the fan at the through hole 11, air can enter through the through hole 11 and exit through the perforations 232 to form a gas circulation. In addition, since the surface temperature of the evaporation plate 10 is relatively low, frost may form on the surface during operation. The use of the perforations 232 can help improve the defrosting efficiency and reduce the downtime required for defrosting, thereby ultimately achieving energy saving and consumption reduction. Please refer again Figure 1 In the embodiment, the evaporation tube 23 is extended to have a square structure as a whole, and the perforations 232 are preferably long strips to make the gas circulation more uniform, which is conducive to uniform temperature; further, the perforations 232 can also be set to other shapes such as circles as needed, and the embodiment is not limited thereto. In an optional embodiment, the evaporation tube 23 is extended to have a circular structure or a zigzag structure as a whole, which will not be described one by one here.

[0029] In addition, the evaporation plate 10 in the embodiment may be provided with a plurality of mounting holes 12 so as to facilitate mounting the evaporation plate 10 as a whole on the side wall of the inner container.

[0030] Although the present invention is described above through embodiments, it should be understood that the above embodiments are only used to exemplarily describe the feasible implementation methods of the present invention, and should not be interpreted as limiting the scope of protection of the present invention. That is, any replacement or change made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection of the claims of the present invention.
