A rivet-free and cold-bridge-free thermal insulation board and its production process

Abstract

The invention relates to the field of heat retaining boards of air conditioners, particularly to a heat retaining board without a rivet or a cold bridge and a manufacturing process of the heat retaining board. The heat retaining board comprises an outer board, an inner board and a foaming layer, wherein folding edges are arranged around the inner sides of both the outer board and the inner board; a heat insulation bar is installed between the folding edge of the outer board and the folding edge of the inner board; a material cavity is formed between the outer board and the inner board; feeding holes are formed in the two sides of the folding edge of the inner board; and the foaming layer is installed in the material cavity. The heat retaining board has the advantages as follows: the design is simple and ingenious, and the structure is scientific and reasonable. According to the process, a notch is formed in the outer side of the solid foaming layer and can clamp the folding edge of the outer board, the heat insulation bar and the folding edge of the inner board tightly and effectively; no rivet is required for connection; heat conduction can be blocked effectively; the processing technology is simple and perfect; the time is saved; and the production cost is saved.

Description

technical field [0001] The invention relates to the field of heat preservation boards for air conditioners, in particular to a heat preservation board without rivets and without cold bridges and a production process thereof. Background technique [0002] In the past, the air-conditioning insulation board used rivets to connect the outer panel and the inner panel. Many rivets were needed, the operation process was cumbersome, the processing technology was complicated, and the manufactured insulation board could not effectively block heat conduction. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a rivet-free and cold-bridge-free thermal insulation board and its production process. The design is simple and ingenious, the structure is scientific and reasonable, no rivet connection is required, and heat conduction can be effectively blocked. The processing technology is simple and perfect, saving time. Production costs a...
