[0009] And a convex member having a protrusion and a base, the base being connected to both sides of the protrusion, the protrusion being inserted into the groove, and the base being located on both sides of the bottom of the concave member.

[0010] In some embodiments, an insulation plate is connected between the upper housing and the lower housing.

[0011] In some embodiments, a first insulating cotton is provided in the gap between the protrusion and the groove.

[0012] In some embodiments, a second insulating cotton is provided at the bottom of the upper housing, and the second insulating cotton is disposed between the convex member and the insulating plate.

[0013] In some embodiments, the top of the upper housing has a vent, one side wall of the lower housing has an air outlet, and the other side wall of the lower housing has an air return outlet.

[0014] In some embodiments, the base is provided with mounting holes.

[0015] In some embodiments, the insulation board has a through hole connecting the upper housing and the lower housing.

[0016] In some embodiments, the convex member and the concave member are hollow rectangular structures.

[0017] This utility model provides a waterproof structure for a top-mounted cold chain unit. Compared with the prior art, this utility model has the following advantages: the waterproof structure for a top-mounted cold chain unit effectively solves the problem of water ingress into the top-mounted unit by setting concave and convex parts.

[0021] Please see Figures 1 to 3 The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0022] like Figure 1 and Figure 3 As shown, this utility model provides a waterproof structure for a top-mounted cold chain unit. The waterproof structure includes an upper shell 1 and a lower shell 2. The upper shell 1 can be equipped with a condenser assembly of the cold chain unit, and the lower shell 2 can be equipped with an evaporator assembly of the cold chain unit.

[0023] like Figure 1 As shown, the upper housing 1 is provided with a ventilation opening 11 at the top, the lower housing 2 is provided with an air outlet 21 on one side wall and an air return opening 22 on the other side wall.

[0024] Specifically, the condensing assembly includes a compressor, oil separator, liquid receiver, condenser, dryer filter, and condensing fan. The evaporating assembly includes an evaporator, expansion valve, and evaporating fan. The condensing and evaporating assemblies of the cold chain unit are existing technologies and will not be described in detail here.

[0025] like Figure 1 As shown, the lower housing 2 can be connected below the upper housing 1.

[0026] like Figure 1 As shown, the waterproof structure of the top-mounted cold chain unit includes an insulation board 3, which can be an XPS insulation board 3. The insulation board 3 can be provided with a through hole 31, which can allow the connecting pipe between the condensing component and the evaporating component to pass through.

[0027] like Figure 2 As shown, the waterproof structure of the top-mounted cold chain unit includes a concave component 4, which is fully welded to the bottom outer edge of the upper shell 1. The concave component 4 is located around the insulation plate 3 and has a groove 41. The concave component 4 can be a hollow rectangular structure.

[0028] like Figure 2 As shown, the waterproof structure of the top-mounted cold chain unit includes a convex member 5 disposed around the insulation board 3. The convex member 5 can be a hollow rectangular structure. The convex member 5 includes a protrusion 51 and a base 52. The base 52 is connected to both sides of the protrusion 51 and is located below the concave member 4. The protrusion 51 and the groove 41 cooperate and are inserted into the groove 41. The gap between the protrusion 51 and the groove 41 can be used to attach a first insulation cotton (not shown in the figure). The thickness of the first insulation cotton can be 3mm. The double cooperation of the convex member 5 and the concave member 4 can effectively achieve waterproofing. The base 52 has a mounting hole 52a.

[0029] When installing the cold chain unit, it can be installed at the mounting opening on the top of the cold chain compartment through the mounting holes 52a on the base 52. After the waterproof structure is installed, waterproof adhesive can be applied to the flange position where the top panel of the compartment is in close contact with the outside of the waterproof structure.

[0030] The waterproof structure of the top-mounted cold chain unit includes a second insulation cotton 6, which can be disposed at the bottom of the upper shell 1. Specifically, the second insulation cotton 6 can be disposed between the convex member 5 and the insulation board 3, and specifically, the second insulation cotton 6 can be attached to the convex member 5 and the insulation board 3 on both sides respectively. The second insulation cotton 6 not only enhances the insulation effect but also effectively prevents moisture from entering the unit's interior.

[0031] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model.
