Special reinforced plastic bottom plate protective frame and doorsill protective frame for refrigerated container

Abstract

The invention discloses a special reinforced plastic bottom plate protective frame and a doorsill protective frame for a refrigerated container, and belongs to the technical field of refrigerated containers. The bottom plate protective frame comprises a bottom plate, a plurality of rib plates parallel to one another and an airflow channel, wherein the rib plates are arranged in the length direction of the bottom plate; a U-shaped groove is defined by the surface of the bottom plate and every two adjacent rib plates; the airflow channel is arranged in the bottom plate in the length direction ofthe bottom plate and comprises an inlet and outlets, the inlet communicates with a cold air source, the outlets communicate with the surfaces of the grooves, and the cold air source inputs cold air into the airflow channel; and the bottom plate comprises a first end and a second end, the inlet of the airflow channel is close to the first end, and a plurality of outlets of the airflow channel aresequentially arranged towards the second end of the bottom plate. According to the special reinforced plastic bottom plate protective frame and the doorsill protective frame for the refrigerated container, the temperature of all areas of an inner cavity of the refrigerated container can be rapidly made to tend to be consistent.

Description

technical field [0001] The invention relates to the technical field of refrigerated containers, in particular to a floor guard and a threshold guard of special reinforced plastics for a refrigerated container. Background technique [0002] A refrigerated container refers to a special container that has good heat insulation and can maintain a certain low temperature requirement, and is suitable for the transportation and storage of various perishable foods. [0003] At present, the commonly used refrigerated container is a mechanical refrigerated container, which is equipped with a refrigeration device, and the top and bottom of the same side are respectively provided with an air return port and an air outlet. flow on the other side. As more and more cold air flows out from the bottom side of the refrigerated container, the cold air gradually flows from the bottom to the top through the surface of the bottom plate, and is finally recovered by the return air outlet, and the r...

AI Technical Summary

Problems solved by technology

[0005] The above problems will lead to: first, before loading the goods, it needs to run the refrigeration device for a long time, so that the temperature in each area of ​​the inner cavity of the refrigerated container reaches the refrigerated temperature; second, the other side farthest from the air outlet and There is a temperature difference on the side where the air outlet is set, which is not conducive to the refrigeration of the goods
