Refrigerator body and refrigerating device

Abstract

The invention discloses a refrigerator body and a refrigerating device. The refrigerator body comprises a refrigerator shell and an inner container, the inner container is placed in the refrigerator shell, and the refrigerator body further comprises a first flow guide part and a second flow guide part which are arranged between the refrigerator shell and the inner container in a spaced mode; the first flow guide part and the second flow guide part are tightly attached to the rear wall of the inner container and the rear wall of the refrigerator shell respectively to form flow guide channels extending vertically, the first flow guide part is a hollow sleeve, and the second flow guide part is a flat sheet-shaped second flow guide sheet. By changing the structure of a sheath of an air returnpipe on the outer side of the inner container, the first flow guide part is matched with the other flow guide piece arranged on the outer side of the inner container, the distribution area of the flowguide channels is increased, the foaming efficiency and quality of foaming materials in cavities of the inner container and the refrigerating shell can be effectively improved, and meanwhile, the flow guide piece and the air return pipe sheath are integrated, so that the manufacturing cost is reduced, field operation is reduced, and production efficiency is improved.

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 ...
