Transport coolers based on phase change materials

Abstract

The invention discloses a transportation refrigeration container based on a phase change material. The transportation refrigeration container comprises a container body, a support plate and a cover body, wherein the container body is composed of a bottom and four side walls, and one end of the container body is closed; the side wall comprises an inner layer wall and an outer layer wall, and a cold insulation space is limited between the inner layer wall and the outer layer wall; a plurality of cold insulation strips are placed in the cold insulation space and are filled with the phase change material; the support plate is arranged in the container body and is connected with the bottom of the container body through a support, and the support comprises at least one elastic component made of shape memory alloy; the cover body is used for covering the opening end of the container body and sealing the container body; the container body is provided with a sealing component along the periphery of the side wall, the sealing component comprises two first sealing rings with a semicircular section, and the opening ends of the first sealing rings are opposite. The transportation refrigeration container has the advantages of simple structure and convenience in operation, prolongs the time limit of preservation of goods, and provides safeguard for the last kilometer of normal-temperature transportation.

Description

Technical field [0001] The invention relates to a transportation device. More specifically, the present invention relates to a transport refrigerated container based on phase change material. Background technique [0002] The food cold chain refers to the processing, storage, and transportation of perishable foods after they are purchased or harvested from the place of production. Distribution. Retail, until it is transferred to consumers, its various links are always in the low temperature environment necessary for products to ensure food quality and safety, reduce consumption, and prevent pollution in a special supply chain system. With the improvement of people's living standards, increasing attention to food safety, and deliberate pursuit of food freshness, low-temperature logistics will become a boom. However, at present, frozen and refrigerated food cannot be more widely used as gift bags and online shopping. The most fundamental reason is that firstly, the last mile del...

Problems solved by technology

But at present, frozen and refrigerated food cannot be widely used as gift packages and online shopping. The most fundamental reasons are that first, the last mile delivery of cold chain food cannot be solved, and second, frozen food cannot be transported at room temperature.

Especially during the last mile delivery process, food damage due to failure to deliver on time frequently occurs
