[0002] Sandwich panels are needed for the installation and use of cold storage. Most of the sandwich panels used in cold storage are polyurethane panels. Since the sealing between sandwich panels is not tight, it is easy to cause the thermal insulation effect to be reduced. After being installed on the wall, it may cause partial or complete fall off of the thermal insulation panel in serious cases.

[0003] And with the increase in demand, the functional requirements for cold storage panels have also increased. For this reason, we propose an insulated sandwich cold storage panel to solve the above problems. Utility Model Content
