Cold air enters the auxiliary air inlet structure 61 through the interval 8 after coming out of the air outlet structure 31, the cold air which is positioned between the four air outlet structures and the four auxiliary air inlet structures and is not blocked by articles on the rack body forms an air curtain similar to a rectangular cylinder shape, the air curtain is not in direct contact with the articles, the air curtain of the cylinder structure can perform sufficient cold and heat exchange with the articles on the internal rack, the required fan power is small, and the refrigeration effect is excellent.
It can be understood that, referring to fig. 4, the positional relationship among the rack body 721, the side wall of the storage space 71 and the side wind covers 2 is: the rack body 721 is connected to the left side wall of the storage space 71 and the right side wall of the storage space 71 through the mounting members 722 positioned at the left and right sides of the rack body 721, the side wind covers 2 are positioned between the rack 72 and the rear side wall of the storage space 71, a space is formed between the left side edge of the rack body 721 and the left side wall of the storage space 71, a space is formed between the right side edge of the rack body 721 and the right side wall of the storage space 71, and a space is formed between the rear side edge of the rack body 721 and the side wind covers 2.
It can be understood that the opening position of the air outlet structure 31 and the opening position of the secondary air inlet structure 61 are preferably "the air outlet structure 31 is opened at an edge of one side of the lower wind shield 3 connected to the side wind shield 2," the air outlet structure 31 is opened at each third turned-over edge 32, the secondary air inlet structure 61 is opened at each fourth turned-over edge, and each air outlet structure 31 corresponds to the corresponding secondary air inlet structure 61. With such an arrangement, the space of the region surrounded by the "air curtain" is relatively large, and the rack body 721 can be correspondingly larger, so that more articles can be placed.
Referring to fig. 3, optionally, guardrails 723 are provided on the upper sides of the edges of the rack body 721.
By providing the guard rail 723 on the upper side of the edge of the rack body 721, articles are prevented from falling from the space 8 between the rack body 721 and the side wall of the storage space 71 or from falling from the space 8 between the rack body 721 and the side wind cover 2.
Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
