Heat preservation express cabinet

Abstract

The invention discloses a heat preservation express cabinet. The heat preservation express cabinet comprises a cabinet body, and the cabinet body comprises a plurality of layers of independent box bodies and a plurality of heat insulation plates; each layer of independent box body comprises a plurality of independent box bodies and front side box doors of the independent box bodies, each independent box body comprises a heat conduction inner box and a heat preservation outer sleeve, an upper protruding part is arranged at the top of each heat conduction inner box, a lower protruding part is arranged at the bottom of each heat conduction inner box, and each heat preservation outer sleeve wraps the left side, the right side and the rear side of each heat conduction inner box; and a pluralityof through grooves are formed in the heat insulation plates at intervals, the lower protruding parts of the bottoms of the heat conduction inner boxes on the adjacent upper layers are embedded into the upper portions of the through grooves in a one-to-one correspondence mode, the upper protruding parts of the tops of the heat conduction inner boxes on the adjacent lower layers are embedded into the lower portions of the through grooves in a one-to-one correspondence mode, semiconductor chilling plates are correspondingly arranged in the through grooves, and the cold ends and the hot ends of every two vertically adjacent semiconductor chilling plates are opposite in direction. Heating and refrigerating of all the independent box bodies are achieved through the semiconductor chilling plates, assembling and disassembling are convenient, and all the independent box bodies can be combined at will.

Description

technical field [0001] The invention relates to the technical field of express cabinets, in particular to an insulated express cabinet. Background technique [0002] The express cabinet can save the time of the takeaway delivery personnel and improve the delivery efficiency. The takeaway (such as food and fresh food) needs to be kept warm and fresh when stored. The normal temperature express cabinet does not have the function of keeping warm and fresh. In short, in order to meet the requirements of heat preservation and freshness of takeaway, heat preservation express cabinets came into being. The semiconductor refrigeration sheet can be used for heating and cooling of the insulated express cabinet. Its working principle is: when a piece of N-type semiconductor material and a piece of P-type semiconductor material are connected to form a galvanic pair, after connecting a DC current in this circuit, it can generate In the transfer of energy, the current flows from the N-type...
