Abstract

The invention discloses a box body and a refrigeration device, which includes a box shell and an inner tank, the inner tank is placed in the box shell, and further includes: a second spacer arranged between the box shell and the inner tank A flow guide part and a second flow guide part, the first flow guide part and the second flow guide part are respectively closely attached to the rear wall of the inner tank and the rear wall of the box shell to form a vertically extending A flow guide channel; wherein, the first flow guide part is a hollow sleeve; the second flow guide part is a flat sheet-shaped second guide piece. By changing the structure of the sheath of the air return pipe on the outside of the inner tank, the first deflector is formed to cooperate with another deflector on the outside of the inner tank, which increases the flow area of ​​the guide channel, and can effectively improve the inner tank and the box shell. The foaming efficiency and quality of the foaming material in the cavity are improved. At the same time, the integration of the deflector and the return air pipe sheath reduces manufacturing costs, reduces on-site operations, and improves production efficiency.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment design, and in particular, relates to a box body and a refrigeration device having the same. Background technique [0002] Ultra-thin smart refrigerators have the advantages of small thickness and large internal volume, so they are favored by consumers. [0003] The box foaming of ultra-thin smart refrigerators and ultra-thin smart freezers generally refers to rigid polyurethane foaming. The foam is between the refrigerator box shell and the liner. After high-pressure mixing by the mixing head of the foaming machine, it is injected into the cavity between the tank shell and the liner to react and release heat. The foaming agent in the raw material is vaporized by heat to form micro-bubbles, which grow and expand to fill the tank. The cavity between the shell and the liner is cured to form a rigid polyurethane closed-cell foam. [0004] At present, for the ultra-thin foam ...
