It should be noted that, an acute angle is formed between the air outlet direction of the first cold air inlet 110 and the door body, which means that the air outlet direction of the first cold air inlet 110 and the inner surface of the door body form an acute angle. Because the junction of the container opening and the door body of the container body 100 is a weak heat-insulating part, if the air flow is blown to the junction of the container opening and the door body along the left side wall or the right side wall of the container body 100, cold air is easy to leak out through the junction of the container opening and the door body. Through making the direction of giving vent to anger of air current and the door body between the acute angle, when cold wind flowed out through first cold wind entry 110, cold wind can not directly blow to courage mouth and door body junction, and this has just avoided cold wind to leak, has improved refrigeration plant's refrigeration efficiency.

The above embodiments are merely illustrative of the present invention and are not to be construed as limiting the utility model. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and the technical solution of the present invention is covered by the claims of the present invention.
