Cold air circulation transport case for cold-chain logistics

Abstract

The invention relates to the field of cold-chain logistics transport equipment, and discloses a cold air circulation transport case for cold-chain logistics. The cold air circulation transport case for cold-chain logistics comprises a transport case body, and a case door is formed in the transport case body; fixing assemblies arranged in pairs are fixed to the top of the transport case body, sliding rods are arranged on the fixing assemblies in a penetrating mode, the sliding rods are in rotating fit with the fixing assemblies, and fans are slidably connected to the sliding rods; power assemblies for driving the fans to move in the length directions of the sliding rods are fixed to the sliding rods; and a lifting assembly for lifting the sliding rods to rotate around the fixing assemblies is further fixed to the top of the transport case body. Cold air can uniformly reach all positions in the transport case through cold air circulation, the low-temperature environment in the transport case is maintained, the temperature in the transport case is prevented from fluctuating, the local low-temperature or high-temperature phenomenon is avoided, and the cold insulation effect of cold chain transport is good.

Description

technical field [0001] The invention relates to the field of cold chain logistics transportation equipment, in particular to a cold air circulation transportation box for cold chain logistics. Background technique [0002] Cold Chain Logistics (Cold Chain Logistics) generally refers to a process in which refrigerated and frozen foods are always in a specified low temperature environment in all links of production, storage, transportation, sales, and consumption to ensure food quality and reduce food loss. systems engineering. It was established with the advancement of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on refrigeration technology and using refrigeration technology as a means. Among them, cold chain transportation (Cold Chain Transportation) refers to the transportation that keeps the transported goods at a certain temperature throughout the entire transportation process, whether it is loadi...

AI Technical Summary

Problems solved by technology

Frequent loading and unloading causes a large amount of cold air to overflow, which increases the temperature inside the transport box, especially the temperature at the door, which is higher than the temperature deep inside the transport box, directly affecting the low temperature environment of cold chain transportation

In the prior art, it is often necessary to increase the cooling capacity of the refrigeration equipment at this time, but it will cause the temperature in the deep part of the transport box to continue to drop, and it is easy to destroy the temperature range of the low-temperature environment.

In view of this, a cold air circulation transport box for cold chain logistics is provided. Through the cold air circulation, the cold air can reach all parts of the transport box evenly, maintain the low temperature environment in the transport box, avoid temperature fluctuations in the transport box, and avoid local low temperature Or high temperature phenomenon, which affects the cold preservation effect of cold chain transportation
