[0002] For refrigeration equipment, the finned evaporator is an important component. The fins and evaporation tubes are combined into an integrated structure. The evaporator circulates air through the fan to cool the storage cavity of the refrigeration equipment. During operation, water droplets will form on the fins of the evaporator, and water bridges may form between adjacent fins, affecting the contact between the fins and the surrounding air, thereby reducing the cooling effect. In addition, the temperature of the evaporator surface is low, and the moisture in the air may even cause frost on the evaporator surface. These situations will directly affect the refrigeration performance of the refrigeration equipment, resulting in reduced refrigeration efficiency and increased energy consumption of the refrigeration equipment.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present utility model, the meaning of "a plurality" is more than two, and "greater than", "less than", "exceed" etc. are understood to exclude the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Figure 1 It is a left view of an embodiment of the utility model. Figure 2 This is a front view of an embodiment of the utility model, referring to Figure 1 , Figure 2 One embodiment of the utility model provides an integrated evaporator.

[0032] Furthermore, the evaporator of the utility model includes a base 100, which is the main structure of the evaporator of the utility model. An evaporation coil 200 is arranged on the base 100, and the evaporation coil 200 has an input end and an output end, and a refrigerant flows in the evaporation coil 200. A plurality of fins 300 are arranged on the evaporation coil 200 to transfer heat with the refrigerant in the evaporation coil 200.

[0033] Further, refer to Figure 3 , Figure 4 The fin 300 is provided with a hydrophilic film 400, and the edge of the hydrophilic film 400 extends to the edge of the fin 300. The hydrophilic film 400 can not only improve the corrosion resistance of the fin 300, but also make the condensed water on the fin 300 quickly spread along the hydrophilic film 400 to the edge of the hydrophilic film 400, and will not condense into water drops.

[0034] Furthermore, the edge of the fin 300 is provided with a rim 310, and a water guide groove 311 is formed between the rim 310 and the fin 300 to guide water droplets scattered on the edge of the hydrophilic film 400. In addition, the design of the rim 310 not only strengthens the structural strength of the fin 300, but also helps to fix the hydrophilic film 400 on the fin 300, so that the hydrophilic film 400 and the fin 300 are not easily separated.

[0035] Furthermore, an opening is left on the edge 310 at the lower side of the fin 300 as a drain port 320 for draining water droplets.

[0036] In actual operation, the low-temperature refrigerant in the evaporating coil 200 exchanges heat with the outside air through the fins 300. Once condensed water is on the fins 300, it can quickly diffuse along the hydrophilic membrane 400 to the edge of the hydrophilic membrane 400 and flow downward along the water guide groove 311, accelerating the drainage until it is discharged from the drain port 320 at the lower side.

[0037] It must be noted that the evaporator of the present invention does not require the fins 300 to be completely dry, but only needs to ensure that water on the fins 300 does not condense on the surface and affect the contact between the fins 300 and the surrounding air.

[0038] In some embodiments, if the fins 300 are arranged vertically, the condensed water mainly flows downward along the vertical water guide grooves 311 on the left and right sides, and is discharged from the drain port 320 on the lower side; if the fins 300 are arranged horizontally, the condensed water flows downward and then spreads to the left and right sides along the lower water guide grooves 311, and is discharged from the drain port 320 on the lower side.

[0039] Some embodiments, see Figure 4The edge 310 is formed by bending or stamping, which facilitates the processing of the edge 310. After the hydrophilic film 400 is attached or placed on the fin 300, the structure is processed by bending or stamping to make the edge 310 clamp the edge of the hydrophilic film 400, so that the hydrophilic film 400 is not easily separated from the fin 300.

[0040] In some embodiments, the cross section of the edge 310 is a “V”-shaped structure. The edge 310 with this structure is not only more solid, but also more conducive to processing the water channel 311 .

[0041] Some embodiments, see Figure 3 The fin 300 is provided with a fin through hole 330, and the evaporating coil 200 is inserted into the fin through hole 330. The edge of the fin through hole 330 has a through hole reinforcement edge 331. The through hole reinforcement edge 331 can not only strengthen the structural strength of the fin through hole 330, but also improve the connection structure between the fin 300 and the evaporating coil 200.

[0042] Some embodiments, see Figure 1 The fin 300 is a corrugated plate structure. This design can increase the contact area between the fin 300 and the outside air, thereby improving the heat exchange efficiency.

[0043] It must be noted that, under the premise that the plasticity of the material of the fin 300 meets the requirements, the corrugated plate design of the fin 300 does not affect the processing of the edge 310 and the water guide groove 311.

[0044] In addition, if the curvature of the corrugated structure of the fin 300 is not large, it will not affect the water flow guiding effect of the water guide groove 311. When the curvature of the fin 300 is large, the water in the water guide groove 311 can directly flow out from the arc-shaped convex part of the fin 300, which can still play a role in accelerating drainage.

[0045] In some embodiments, the fins 300 are made of aluminum sheets, which facilitates the processing of the fins 300 and ensures the heat exchange efficiency of the fins 300 .

[0046] Some embodiments, see Figure 2 A pipe mouth reinforcement plate 110 is arranged between the input end and the output end of the evaporating coil 200 and the base 100 to fix the input end and the output end position of the base 100 from which the evaporating coil 200 extends, so as to ensure that the external pipes of the input end and the output end of the evaporating coil 200 will not be loosened.

[0047] Some embodiments, see Figure 1 , Figure 2 A mounting seat 120 is disposed at the lower side of the base 100 , and a mounting hole is disposed on the mounting seat 120 . The evaporator of the utility model is fixedly installed by screws on the mounting hole of the mounting seat 120 .

[0048] In some embodiments, a spring sheet 130 is disposed on the upper side of the base 100, and a pendulum 140 is disposed on the spring sheet 130, so that the pendulum 140 can swing along the spring sheet 130. In actual operation, the evaporator of the utility model often generates vibrations when the device is working, and the swinging back and forth of the pendulum 140 and the spring sheet 130 can amplify the vibration, so that the water on the fin 300 can flow down more easily.

[0049] In this embodiment, optionally, the spring piece 130 and the base 100 are integrally formed to facilitate processing.

[0050] In this embodiment, optionally, the spring piece 130 and the base 100 can be connected by screws or other means.

[0051] In the description of this specification, the description with reference to the terms "some embodiments" or "it is conceivable that" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0052] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
