Heat preservation box for refrigerated lorry

Abstract

The invention discloses a heat preservation box for a refrigerated lorry. The heat preservation box comprises a heat preservation box body arranged in the refrigerated lorry, wherein the heat preservation box body comprises a top plate and a bottom plate, two side plates and two end plates are arranged between the top plate and the bottom plate, one of the two side plates is hinged to a door platethrough hinge pieces, and the end plate which is far away from a head end is provided with a door plate through hinge pieces; the door plates, the top plate, the bottom plate, the side plates and theend plates all comprise polyurethane protection layers, a vacuum heat insulation structure is arranged in each of the polyurethane protection layers, and panels are arranged on the sides, far away from the refrigerated lorry, of the polyurethane protection layers; and a vent hole is formed in the top plate, and a wire hole is formed in the end plate close to the head end. According to the heat preservation box, thermal transmission caused by cross-ventilation is effectively avoided through the vacuum heat insulation structures in the polyurethane protection layers, and therefore the heat conduction coefficient is greatly reduced, the long-time heat preservation effect is good, and the heat insulation capability is high; the wall thickness of the heat preservation box body is thin, and therefore the use volume and the space utilization rate of the heat preservation box body are greatly increased; and meanwhile, the heat preservation box has the advantages of being efficient, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of refrigerated vehicles, in particular to an incubator for refrigerated transport vehicles. Background technique [0002] At present, most of the refrigerated transport vehicles used to transport items that need to be refrigerated (such as: pharmaceuticals, etc.) are refitted from vans. It is made of thick polyurethane board and glass fiber reinforced plastic panel. Although the refrigerated transport vehicle with the above-mentioned structure can have a certain heat preservation effect, the heat preservation effect is poor, and the refrigeration equipment is basically in operation, and the energy consumption is high. Moreover, the thick heat insulation layer will occupy a large amount of space in the car, resulting in The space (insulation space) utilization rate is greatly reduced. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an incubator for...
