Pressed sheet steel heating radiator - has panels with pressed bulges and edge flanges asymmetrically welded

摘要

The heating radiator is made from sheet metal panels with pressed side bulges, which increase the heating surface area and ensure high heating efficiency. The heat conducting plates area rranged asymmetrically and the plate external end flanges are turned outwards. These flanges have rectangular channel cross section. The flange free edge channel side depth is smaller than the channel side on conducting plate. The heat conducting plates which are not visible are provided with slots. A sheet metal strip (18) is formed on one edge of the connecting plate for compensating tolerance on making outside welded joint.
