[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the utility model, and provides an evaporator for a test box, which can improve the anti-corrosion performance of the evaporator, including an evaporator body 1, the evaporator body 1 is in an arc shape, the evaporator body 1 includes an arc-shaped evaporation pipe 2, heat dissipation fins 3 evenly spaced along the arc bending direction of the evaporation pipe 2, a first side plate 4, a second side plate 5 and an arc-shaped wind shield 6, a refrigerant flows in the evaporation pipe 2, and the evaporation pipe 2 passes through each heat dissipation fin 3;

[0028] The evaporation pipe 2 includes a plurality of first arc-shaped tubes 21 and a plurality of first connecting elbows 22. The first arc-shaped tubes 21 are parallel to each other on a vertical plane. The first connecting elbow 22 connects two first arc-shaped tubes 21 adjacent in the vertical direction. A flow guide gap is left between two first arc-shaped tubes 21 adjacent in the vertical direction, and a heat dissipation gap is left between two adjacent heat dissipation fins 3.

[0029] The arc-shaped wind shield 6 is located on the outer side of the evaporation pipe 2. A plurality of arc-shaped dehumidification plates 18 made of dehumidification material are provided on the side of the arc-shaped wind shield 6 facing the evaporation pipe 2. Each arc-shaped dehumidification plate 18 is located in the overlapping space of the guide gap and the heat dissipation gap. Each arc-shaped dehumidification plate 18 is parallel to each first arc-shaped pipe 21.

[0030] The first side plate 4 and the second side plate 5 are respectively fixed to the left and right ends of the evaporation pipe 2. The first side plate 4 is provided with at least one first blowing device 7, and the second side plate 5 is provided with at least one second blowing device 8. The first blowing device 7 is used to blow air toward the evaporation pipe 2, and the second blowing device 8 is used to discharge the wind on the evaporation pipe 2 to the outside.

[0031] Preferably, the inner wall of the evaporation pipe 2 is uniformly coated with an anti-corrosion coating.

[0032] Specifically, in this embodiment, by uniformly coating the inner wall of the evaporation pipe 2 with an anti-corrosion coating (not shown in the figure), the anti-corrosion performance of the evaporation pipe 2 can be further improved.

[0033] Preferably, the heat dissipation fins 3 are wavy in shape.

[0034] Specifically, in this embodiment, by configuring the heat dissipation fins 3 to be wavy, the heat dissipation area between the heat dissipation fins 3 and the air can be further increased, thereby improving the heat dissipation performance of each heat dissipation fin 3 .

[0035] Working principle of embodiment 1:

[0036] When the refrigerant introduced by the refrigeration device circulates in the evaporation pipe 2, since the evaporation pipe 2 is arranged in an arc shape, the contact area between the evaporation pipe 2 and the air is larger than that of the prior art, so the evaporation heat dissipation effect is better. When the first blowing device 7 installed on the first side plate 4 and the second blowing device 8 installed on the second side plate 5 are in operation, the high-temperature, humid and hot air around the evaporation pipe 2 is blown to flow, and the arc-shaped wind shield 6 limits the air flow, so that the air is concentrated to flow around the evaporation pipe 2 to improve the heat dissipation and dehumidification effect. At the same time, when the concentrated high-temperature, humid and hot air flows through the arc dehumidification plate 18 interspersed between the first connecting elbows 22 on the arc-shaped wind shield 6, due to the dehumidification characteristics of the arc dehumidification plate 18, the high-temperature, humid and hot air flowing around the evaporation pipe 2 is further dehumidified, and the dehumidification effect is further improved. Therefore, this embodiment simultaneously reduces the temperature and humidity in the air around the evaporation pipe 2, avoiding the high-temperature, humid and hot environment causing the evaporator to be corroded by chemical reactions, thereby significantly improving the corrosion resistance of the evaporator.

[0037] Example 2, reference Figure 3, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides an evaporator for a test box, which can adjust the air flow direction between each first arc tube 21, and includes: a plurality of pairs of fixed side panels 9 are provided on the arc wind shield 6, and the arc dehumidification plate 18 is detachably mounted on a swing support plate 19.

A synchronous wheel 11 is fixedly sleeved on the swing shaft 10, and a synchronous belt 12 is connected between each synchronous wheel 11.

[0038] Working principle of embodiment 2:

[0039] The arc-shaped dehumidification plate 18 can not only be used to dehumidify the area around the evaporation pipe 2, but also guide the air flow around the evaporation pipe 2. When the air flow around the evaporation pipe 2 needs to adjust the blowing direction in the vertical direction, one of the swing support plates 19 can be driven manually or by a mechanism to adjust the direction, and then the other swing support plates 19 will adjust the direction synchronously, thereby achieving the adjustment of the guiding direction of the arc-shaped dehumidification plate 18.

[0040] Preferably, Figure 4 As shown, a limiting groove is provided on the swing support plate 19, and the limiting groove is adapted to the shape of the arc-shaped dehumidification plate 18. A plurality of buckles 14 are also provided on the swing support plate 19, and a plurality of buckle grooves are provided on the arc-shaped dehumidification plate 18, and the buckle grooves are adapted to the shape of the buckles 14. When the arc-shaped dehumidification plate 18 is inserted into the limiting groove, each buckle 14 is connected with the buckle 14 of the corresponding buckle groove.

[0041] Specifically, in this embodiment, by providing a limit groove on the swing support plate 19 and a buckle groove on the arc dehumidification plate 18, it is convenient to cooperate with the arc dehumidification plate 18 and a number of buckles 14 thereon to realize the rapid installation and disassembly of the arc dehumidification plate 18 on the swing support plate 19, thereby facilitating the replacement of the arc dehumidification plate 18.

[0042] Example 3, reference Figure 5 to Figure 6 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an evaporator for a test box, which can improve the uniformity of heat dissipation and dehumidification of the evaporator, and includes: the first blowing device 7 and the second blowing device 8 are both fan assemblies, and the fan assembly includes a bracket 81, a blower motor 82, blades 83 and a dehumidification filter 84.

[0045] Specifically, in this embodiment, by providing a dehumidification filter 84 at the air outlet end of the blade 83, the high-temperature hot and humid air can be further dehumidified, thereby improving the dehumidification effect of the evaporator.

[0046] Working principle of embodiment 3:

[0047] The driving motor 161 drives the screw rod 162 to rotate, drives the sliding seat 163 to slide up and down on the screw rod 162, and drives the fan assembly to move up and down in the vertical direction. The universal connector 166 with drive drives the fan assembly to swing back and forth, so that in this embodiment, the fan assembly can be lifted and swung back and forth in the process of promoting air circulation around the evaporation duct 2, so that the wind blowing around the evaporation duct 2 can be more uniform, thereby improving the heat dissipation and dehumidification uniformity of the evaporator.

[0048] Preferably, it also includes an arc-shaped dehumidification pipe (not shown), which is located on the side of the evaporation pipe 2 away from the arc-shaped wind shield 6. The outside of the dehumidification pipe is sleeved with a dehumidification sleeve (not shown) made of dehumidification material.

[0049] Specifically, in this embodiment, by arranging a dehumidification pipe 17 inside the evaporation pipe 2, the dehumidification effect of the evaporator is further improved by utilizing the dehumidifier inside the dehumidification pipe 17 and the external dehumidification sleeve.
