Title:
COLD STORAGE PLUGGING DEVICE, THERMAL PRESERVATION BOX AND METHOD FOR REPLACING COLD STORAGE BODY
Document Type and Number:
WIPO Patent Application WO/2020/057341
Kind Code:
A1
Abstract:
Disclosed are a cold storage plugging device, a thermal insulation box, and a method for replacing a cold storage body, which are related to the technical field of thermal insulation. The cold storage plugging device comprises a cold storage body (1) and a plugging cover (2). The cold storage body comprises a shell and a refrigerant, and the refrigerant is contained inside the shell, and the shell is connected to the plugging cover. The thermal insulation box comprises a box body (5) and the cold storage plugging device, wherein the box body is provided with a first opening (6), through which the cold storage body can be inserted into the box body, and the plugging cover can plug the first opening in a fitted manner. The method for replacing a cold storage body is used for replacing the cold storage body inside the thermal insulation box. The cold storage plugging device has fewer operation steps and is less time consuming during replacement, and shortens the heat exchange time between goods and the outside air, so as to reduce the heat exchange between the goods and the outside air and reduce the change in temperature of the goods during the replacement of the cold storage body, thereby reducing the negative influence on the quality of the goods due to the relatively long time required to replace the cold storage body. In addition, with the cold storage plugging device, the automation of a replacement operation is easily achieved, thereby further improving the replacement efficiency.
