[0026] See Figure 1-Figure 7 As shown, this specific embodiment adopts the following technical scheme: it includes a refrigerator liner 1, a circulating air duct 2, a fin evaporator 3, an aluminum foil sponge 4, an air duct aluminum foil sponge 5, an aluminum water receiving tray 6, a supporting bracket 7, and a drain pipe 8; the circulating air duct 2 is horizontally arranged at the bottom of the inner side of the refrigerator liner 1, and the tail of the circulating air duct 2 is overlapped on the supporting bracket 7 at the upper end of the aluminum water receiving tray 6; the aluminum water receiving tray 6 is arranged at the right end of the bottom of the refrigerator liner 1; the fin evaporator 3 is arranged in the inner groove at the lower end of the right side of the circulating air duct 2, an air duct aluminum foil sponge 5 is arranged between the upper end of the fin evaporator 3 and the circulating air duct 2, and an aluminum foil sponge 4 is arranged between the fin evaporator 3 and the refrigerator liner 1.

[0027] Among them, the circulating air duct 2 is composed of a circulating chamber 21 at the front end and a supporting base plate 22 at the rear end; the circulating chamber 21 and the supporting base plate 22 are an integrated structure, and a hollow chamber is arranged inside the circulating chamber 21; a return air port 26 is arranged at the tail of the supporting base plate 22, and a guide rib 27 is arranged at the front end of the return air port 26; an air outlet 1 23 and an air outlet 2 24 are respectively arranged on the front and rear sides of the upper surface of the circulating chamber 21; a circulating fan 25 is arranged in the middle of the lower surface of the circulating chamber 21.

[0028] Furthermore, the air outlet 1 23 and the air outlet 2 24 maintain the same length, and the width of the air outlet 1 23 is 3-5 times the width of the air outlet 2 24; a pair of heaters 31 are connected to the tail of the fin evaporator 3, and the middle of the heater 31 is an outward convex structure, and the middle is connected to the drain pipe 8 in the middle of the aluminum water receiving tray 6 through a heat-conducting aluminum sheet 32.

[0029] Furthermore, the aluminum foil sponge 4 and the drain pipe 8 are maintained on the same horizontal plane, and a water guide groove structure with a high front and a low back is provided on the surface of the aluminum foil sponge.

[0030] Furthermore, the air outlet 1 23 and the air outlet 2 24 are blown under the action of the circulating fan 25. Due to the difference in the air outlets of the air outlet 1 23 and the air outlet 2 24, a pressure difference between the inside and the outside is formed to realize an inward blowing air path; the air duct aluminum foil sponge 5 is replaced by a guide plate 27; the guide plate 27 is staggered at the bottom of the supporting base plate 22, and the side wall of the guide plate 27 is provided with a guide prism 28; the interior of the circulating chamber 21 is provided with a silver ion-loaded activated carbon mixed filling bag to realize simple circulation antibacterial.

[0031] The working principle of this specific implementation is:

[0032] A. The circulation fan 25 is arranged at a distance of more than 25 mm from the lower surface of the circulation chamber 21 to the fin evaporator 3 to prevent the circulation fan 25 from being too close to the fin evaporator 3 and causing the circulation fan 25 to be frozen; the upper surface of the circulation chamber 21 is arranged with an air outlet 1 23 and an air outlet 2 24 for heat exchange circulation;

[0033] B. The finned evaporator 3 assembly consists of an evaporator and a heater 31. The bottom of the heater 31 is connected to a heat-conducting aluminum sheet 32 ​​and extends into the drain pipe 8 to avoid freezing and blocking;

[0034] C. A guide rib 27 is provided at the rear end of the support bottom plate 22. During the defrosting stage, water on the air duct surface flows into the water receiving tray along the guide rib 27 to avoid flowing into the return air port 26 and causing ice to form at the return air port 26;

[0035] D. Air circulation: During the operation of the compressor, the circulating fan 25 draws air through the gap and blows out dry cold air from the air outlet 1 23 and the air outlet 2 2 at the upper end of the circulation chamber 21. In order to allow the cold air to flow into the cooling box as much as possible, the cross-sectional area of ​​the air outlet 1 23 should be larger than that of the air outlet 2 2. After cooling, the warm air enters the fin evaporator 3 from the return air port 26 to be dried and cooled again, forming an air circulation to complete the refrigeration process.

[0036] E. To prevent the finned evaporator 3 from being seriously frosted due to long-term operation and to reduce the evaporation area, the compressor is shut down after a period of cumulative operation, and the tail heater 31 of the finned evaporator 3 starts to work to defrost the finned evaporator 3; after defrosting, the defrosted water is discharged along the drain pipe 8 of the aluminum water receiving tray 6, and the drain pipe 8 directly extends to the outside of the vehicle, completing the defrosted water drainage process;

[0037] F. To prevent the fin evaporator 3 from hard contact with the refrigerator liner 1 and the circulating air duct 2, an aluminum foil sponge 4 and an air duct aluminum foil sponge 5 are added. After assembly and installation, the return air can completely pass through the fin evaporator 3, thereby improving the heat exchange efficiency;

[0038] G. The interior of the circulation chamber 21 is provided with silver ion-carrying activated carbon which can contact with the circulating air and inhibit the bacteria of the cold air.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
