Problems solved by technology

In the prior art, refrigerated transportation usually adopts large-scale containers that are refrigerated by electric compressors, that is, commonly referred to as active refrigerated transport boxes; If a full container of goods such as precision electronic components or medicines is transported in an active refrigerated transport box, it is necessary to provide electrical energy to ensure the normal operation of the electric compressor during transportation, especially when transporting small items or requiring different refrigerated temperatures The transportation cost is increased during the transportation of mixed items

Embodiment 1

[0021] In this embodiment, the shell layer and the shell layer are both made of carbon steel, and the thickness of the shell layer and the shell layer is 2-20 mm; the thickness of the vacuum insulation panel layer is 10 mm, and the first hard The thickness of the first rigid polyurethane foam is 25mm, and the thickness of the second rigid polyurethane foam is 25mm. And, the first rigid polyurethane foam and the second rigid polyurethane foam are made of 22.0wt% carbodiimide modified MDI, 18.0wt% PEA-1000, 7.5wt% PEBA-1000, 2.5 wt% of hydroxyl-terminated polybutadiene, 3.0wt% of polyvinylamine resin (molecular weight is 800), 1.6wt% of polydimethylsiloxane, 0.20wt% of triethylenediamine, 12.0wt% of The composition of cyclopentane, 1.2wt% of water and the rest of ethyl acetate is uniformly mixed and poured.

Embodiment 2

[0023] In this embodiment, the shell layer and the shell layer are both made of carbon steel, and the thickness of the shell layer and the shell layer is 2-20 mm; the thickness of the vacuum insulation panel layer is 10 mm, and the first hard The thickness of the first rigid polyurethane foam is 25mm, and the thickness of the second rigid polyurethane foam is 25mm. And, the first rigid polyurethane foam and the second rigid polyurethane foam are made of 22.0wt% carbodiimide modified MDI, 18.0wt% PEA-1000, 7.5wt% PEBA-1000, 2.0 wt% of hydroxyl-terminated polybutadiene, 3.0wt% of polyvinylamine resin, 1.6wt% of polydimethylsiloxane, 0.20wt% of triethylenediamine, 12.0wt% of cyclopentane, 1.2 It is obtained by uniformly mixing the composition of wt% water and the balance of ethyl acetate and pouring.

Embodiment 3

[0025] In this embodiment, both the shell layer and the shell layer are made of carbon steel, and the thickness of the shell layer and the shell layer is 2-20 mm; the thickness of the vacuum insulation panel layer is 10 mm, and the first hard The thickness of the first rigid polyurethane foam is 25mm, and the thickness of the second rigid polyurethane foam is 25mm. And, the first rigid polyurethane foam and the second rigid polyurethane foam are made of 22.0wt% carbodiimide modified MDI, 18.0wt% PEA-1000, 7.5wt% PEBA-1000, 2.5 wt% of hydroxyl-terminated polybutadiene, 3.0wt% of polyvinylamine resin, 1.6wt% of polydimethylsiloxane, 0.20wt% of triethylenediamine, 12.0wt% of cyclopentane, 0.8 It is obtained by uniformly mixing the composition of wt% water and the balance of ethyl acetate and pouring.

Abstract

The invention relates to a passive vehicle-mounted refrigerator, comprising an insulation box body and a refrigerant; the main body of the insulation box body is formed by a top wall part, a bottom wall part, a front wall part, a rear wall part, a left wall part and a right wall part; the left wall part is an openable structure; the front wall is provided with a front side door; each wall part comprises an outer shell layer, a vacuum thermal insulation panel and an inner shell layer; first hard polyurethane foam bodies are injected between the outer shell layers and the vacuum thermal insulation panels; second hard polyurethane foam bodies are injected between the inner shell layers and the vacuum thermal insulation panels. The passive vehicle-mounted refrigerator adopts the direct refrigeration mode that the refrigerant is vaporized to absorb heat and is diffused into the thermal insulation box body, and a power supply system powered by an electrical compressor does not need to be adopted, so the plot ratio of the whole cold storage refrigerator is greatly improved. Compared with the prior art, the passive vehicle-mounted refrigerator has the advantages that the investment is low and the transportation cost for the transportation of a few or different types of objects is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerated transportation, more specifically, the invention relates to a passive vehicle refrigerator. Background technique [0002] Refrigerated transport devices refer to facilities and devices that can maintain a certain low-temperature environment and transport low-temperature goods; and refrigerated containers are the last link in the cold chain. Refrigerated transportation should have good cold insulation and ventilation equipment; the box body should have good heat insulation performance, should have certain ventilation equipment, and can be cleaned; it should have the characteristics of heavy load, large effective volume, light weight, and good applicability. Items that require refrigerated transportation mainly include fresh vegetables, fruits, aquatic products and other foods, and usually include smaller items such as medicines, vaccines, and electronic components. In the prior art, refriger...
