Specifically, an insulating layer is provided on a side of the cover plate (not shown in the drawings) facing the installation space 1031. The refrigerating system 200 can be insulated by arranging the heat insulation layer, so that the refrigerating effect of the refrigerating system 200 is ensured.

It should be pointed out that the heat preservation is PU bubble cotton or vacuum insulation panels etc. and the heat preservation is the cost low of PU bubble cotton in this application, and the heat preservation effect is good, can effectively reduce the cost of manufacturing under the prerequisite that satisfies the user demand.

In addition, the refrigeration device may be a showcase, a refrigerator, and the like, and other structures of the refrigeration device are referred to in the prior art, and are not described herein again.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
