Problems solved by technology

Although the cold leakage problem of this kind of carriage has been improved, it is formed by splicing and foaming multiple boards, and the processing procedure is complicated, and because the foaming material is used as both an insulation material and an adhesive, it is easy to cause weak bonding , the thermal insulation effect is not ideal, and the structural strength of the car body is low

Abstract

The invention provides a cold storage and thermoregulation carriage, and a manufacturing method and application thereof. The carriage comprises an outer skin carriage (1), an inner skin carriage (2), a lightweight sandwich framework material (3) and a heat-preservation foam material (4), wherein the outer skin carriage (1) and the inner skin carriage (2) form an integrated structure; the heat-preservation foam material (4) is filled with low-temperature phase change cold accumulation material microcapsules; and the whole carriage is formed by resin curing and foaming reaction cementation. The cold storage and thermoregulation carriage has an integrated structure, is simple in structure and easy and convenient to manufacture, and has heat-preservation performance and cold accumulation energy saving and automatic thermoregulation functions, and the cold energy loss of the carriage can be effectively reduced.

Description

technical field [0001] The invention relates to the field of refrigerated and temperature-regulated cars, in particular to a refrigerated and temperature-regulated car body, its manufacturing method and application. Background technique [0002] At present, there are three main types of refrigerated and insulated carriages in the domestic market: the first type is that the inner and outer layers are metal plates, the middle is a metal skeleton filled with foam materials, and the carriage is welded by metal; the second type is that the middle is a foam board The inner and outer layers are "sandwich" structural materials of glass fiber composite boards, and the carriage is bonded by adhesives; the third type is to use six "sandwich" composite boards to splice and combine in the original carriage, and then use the profiles in the original carriage. Fastened and formed at the corners. The disadvantages of the above three kinds of carriage bodies are: the first type of carriage ...
