Mobile air-cooled cold storage box

Abstract

The invention provides a mobile air-cooled cold storage box, and belongs to the technical field of cold chain transportation. The mobile air-cooled cold storage box solves the problem that an existingmobile air-cooled cold storage box is poor in refrigerating performance. The mobile air-cooled cold storage box comprises a heat preservation box body and a refrigeration module arranged on the heatpreservation box body and used for refrigerating air inside the heat preservation box body, and the refrigeration module is provided with an air inlet used for sucking air flowing out from the heat preservation box body and an air outlet for discharging the refrigerated air. The mobile air-cooled cold storage box is characterized in that the upper end surface of the heat preservation box body is provided with single through holes for the air in the heat preservation box body to flow out and the refrigerated air discharged from the refrigeration module to flow in, the air inlet and the air outlet are both arranged at the single through holes and communicate with the single through holes, the position of the air inlet is higher than the position of the air outlet, and the area of the air inlet is larger than the area of the air outlet. The refrigerating effect of the mobile air-cooled cold storage box with the refrigeration module is improved.

Description

technical field [0001] The invention belongs to the technical field of cold chain transportation, and in particular relates to a mobile air-cooled cold storage box. Background technique [0002] As consumers have increasingly demanding food quality, the demand for cold chain transportation of various refrigerated and frozen foods has become increasingly prominent. Foam insulation boxes are commonly used in cold chain transportation. However, the insulation effect and insulation time of foam insulation boxes are very limited, and it is difficult to meet the requirements of long-distance cold chain transportation. In order to prolong the heat preservation time of the heat preservation box, existing manufacturers have added refrigeration components on the heat preservation box to make a mobile air-cooled cold storage box that can be refrigerated by itself. Among them, the refrigeration assembly has an air inlet for sucking the air flowing out of the insulation box and an air o...

Problems solved by technology

In this technical solution, each refrigeration device is fixedly installed on the housing through a bracket to realize the modular setting of the refrigeration assembly. If the distance is too short, the cold air at the air inlet and the hot air at the air outlet are likely to cross each other, resulting in a short circuit of the cold air, which affects the cooling effect of the refrigeration unit on the insulation box, and even causes the refrigeration unit to fail to operate normally.

At the same time, in order to ensure the air circulation at the air inlet and the air outlet, in this technical solution, the brackets for installing each refrigeration device are arranged on different side walls of the housing, which makes it difficult to assemble the refrigeration unit, and the structure of the refrigeration unit is complex and difficult. Conducive to improving the installation convenience of the refrigeration unit
