Description

A refrigerated container with air channel guide groove

technical field

The utility model relates to a refrigerated container, in particular to a refrigerated container with an air duct diversion groove.

Background technique

A refrigerated container is a container specially designed to maintain a certain temperature for the transported goods. It is a temporary warehouse for refrigerated food (such as fish, meat, fresh fruits, vegetables, etc.).

The interior of the refrigerated container is equipped with a cold air circulation system. At present, the cold air circulation system widely used at home and abroad is the down-feed and up-return type, that is, the cold air blown out by the refrigeration device is blown out from the air outlet at the bottom of the box, and passes through the goods, the inner panel of the box, the door panel, and absorbs The heat rises to the upper part of the box, and finally is sucked by the cooling fan, and then passes through the evaporator to absorb heat, and then blows it out from the lower part after cooling down. This kind of cold air circulation realizes the cooling in the box. Fans with forced circulation need to run continuously except during the defrosting period, which consumes a lot of electricity.

There are also some refrigeration devices that blow out the cold air from the air outlet on the front side wall. Since the container body is relatively long, and the inner wall of the refrigerated container generally adopts a wall without a guide channel, the cold air sent from the air outlet on the front side wall arrives. At the end, there will be the disadvantage that the temperature difference between the front and the back is too large, which makes the air distribution in the box extremely uneven, and the temperature near the door is higher. This air supply method cannot ensure the low-temperature refrigeration environment of all the goods in the container. resulting in food spoilage. In order to solve this problem, the technicians sent the cold air blown by the refrigeration device into the aluminum base plate. Since the aluminum base plate is a structure similar to overhead, the cold air can quickly and smoothly pass through the entire space of the entire container in the gaps of the aluminum base plate. The temperature difference between the front and rear is very small to meet the needs. However, the arrangement of the aluminum bottom plate not only increases the overall cost of the refrigerated container, but also reduces the accommodation space inside the refrigerated container.
