However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0019] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0020] See Figure 1-Figure 5 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, and a support bracket 7; the circulating air duct 2 is horizontally arranged at the bottom inner side of the refrigerator liner 1, and the tail of the circulating air duct 2 is overlapped on the support 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, and 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.

[0021] 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 provided inside the circulating chamber 21; the tail of the supporting base plate 22 is provided with a return air outlet 26, and the front end of the return air outlet 26 is provided with a guide rib 27; the front and rear sides of the upper surface of the circulating chamber 21 are respectively provided with an air outlet 1 23 and an air outlet 2 24; a circulating fan 25 is provided in the middle of the lower surface of the circulating chamber 21.

[0022] 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; the tail of the fin evaporator 3 is connected to a pair of heaters 31, 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.

[0023] The working principle of this specific embodiment is:

[0024] 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 freeze. The upper surface of the circulation chamber 21 is provided with an air outlet 1 23 and an air outlet 2 24 for heat exchange circulation.

[0025] 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.

[0026] C. The rear end of the support base plate 22 is provided with guide ribs 27. During the defrosting stage, water on the air duct surface flows along the guide ribs 27 into the water receiving tray to avoid flowing into the return air outlet 26 and causing ice to form at the return air outlet 26.

[0027] D. Air circulation: When the compressor is running, 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.

[0028] E. To prevent severe frost on the finned evaporator 3 due to long-term operation and reduce the evaporation area, the compressor is shut down after a period of cumulative operation. 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. The drain pipe 8 directly extends to the outside of the vehicle, completing the defrost water drainage process.

[0029] F. In order to prevent the fin evaporator 3 from hard contact with the refrigerator liner 1 and the circulation air duct 2, aluminum foil sponge 4 and 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.

[0030] 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 in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method 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 can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
