Integrated refrigerator car carriage structure and operating method thereof

Abstract

The invention discloses an integrated refrigerator car carriage structure. The carriage comprises a protective layer and an insulating layer. The insulating layer consists of six surfaces, that is, a left side plate, a right side plate, a top plate, a bottom plate, a front closing plate and a rear closing plate which are formed by pouring polyurethane material; the insulating layer and the protective layer are mutually bound to form a whole body, and the insulating layers of carriage plates of various surfaces are in gapless connection and are of the integrated structure. The operating method of the integrated refrigerator car carriage comprises the following steps: A) the front closing plate and the bottom plate are arranged; B) the bottom plate is taken as a base, the two sides and the top face of the carriage are provided with inner covering, and filling space is left between the inner covering and the protective layer; C) the carriage is internally equipped with a foaming formwork which is jointed with the inner covering; D) a filling groove is filled with a polyurethane foaming material; and E) the rear closing plate and a rear door are mounted. The refrigerator car carriage is characterized by simple structure, convenient manufacture, high space utilization rate and good insulating property; and the refrigerator car carriage can effectively reduce cold energy loss of the carriage.

Description

technical field [0001] The invention relates to a compartment of a refrigerated vehicle, in particular to an irregular refrigerated compartment, in particular to an integrated sealing structure of the compartment of a refrigerated vehicle and a working method of the structure. Background technique [0002] At present, the irregular refrigerated carriages in the domestic market mainly use six flat composite panels to assemble and combine in the original carriages, and then use profiles to fasten and form the corners. The bottom panel, top panel, left side panel, right side panel, front sealing panel, and rear sealing panel (including the rear door) that make up the refrigerated compartment are all made of sandwich panels, and the panels need to be bonded with double-sided panels and more glue , the amount of material used is large, the manufacturing cycle is long, and the cost is high; the lamination of each compartment plate and the original compartment surface is poor, and ...
