Technical Field

The utility model relates to the technical field of refrigerators, in particular to a cold storage type movable refrigerator.

Background Art

With the rapid development of the logistics industry and self-driving tourism, the demand for cold chain transportation has become more and more obvious. Many foods and medicines need to be refrigerated during transportation. Among them, cold storage mobile refrigerated boxes use special materials or structures to give full play to the insulation function of the box itself and maintain a low temperature environment inside the box.

At present, car refrigerators are divided into three categories: compressor car refrigerators, semiconductor car refrigerators and ice storage plate passive car refrigerators. Among them, the ice storage plate passive car refrigerator mainly uses the cold storage function. In order to be placed more stably in the car, most of the above refrigerators are not equipped with rollers to assist the movement of the refrigerator on the road and other storage surfaces. In particular, compressor car refrigerators are heavy and large compared to the other two categories, and are inconvenient to move. In view of this, we propose a cold storage type movable refrigerator.
