In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0024] According to the first aspect of the present disclosure, referring to Figures 1 to 5 As shown in the figure, a vehicle refrigerator is provided, which includes a box body 3, an air duct 1 and a fan 2, the box body 3 includes an air inlet 41 and an air outlet 42, two opposite box walls of the box body 3 are respectively provided with air inlets 41, the air outlet 42 is located between the two air inlets 41, the fan 2 is arranged at the air outlet 42, the air duct 1 is arranged outside the box body 3 and is connected with the interior of the box body 3 through the air inlet 41 and the air outlet 42, and the fan 2 is used to circulate the air inside the box body 3 between the box body 3 and the air duct 1.

[0025] Through the above technical solution, in the vehicle refrigerator provided by the present disclosure, the air duct 1 is connected with the box 3 and is arranged outside the box 3, and the fan 2 can make the air inside the box 3 circulate in the box 3 and the air duct 1, so that the air inside the box 3 can continuously flow in the box 3 and the air duct 1, so that the air in different areas of the box 3 can be continuously exchanged, ensuring that the temperature inside the box 3 is evenly distributed, improving the efficiency of cooling or heating of the vehicle refrigerator, and thus improving the working efficiency of the vehicle refrigerator. In addition, the two opposite box walls of the box 3 are respectively provided with air inlets 41, the air outlet 42 is located between the two air inlets 41, and the fan 2 is arranged at the air outlet 42. In this way, the air in the box 3 can enter the air duct 1 from the middle position of the box 3 through the air outlet 42, and after circulating in the air duct 1, it flows into the box 3 from the positions on both sides of the box 3. Compared with only one air inlet 41 and one air outlet 42 , the above arrangement enables the air in the middle of the box body 3 to be mixed more fully with the air around the box body 3 .

[0026] In addition, the air duct 1 is arranged outside the box 3, which can ensure the usable space inside the box 3. Compared with arranging the air inlet 41 and the air outlet 42 on the same box wall of the box 3, arranging the air outlet 42 and the air inlet 41 on different box walls of the box 3 can extend the flow path of the air in the box 3, so that the air in the box 3 can be mixed more evenly, so as to improve the temperature uniformity effect of the vehicle refrigerator.
