PACK OF HEAT TRANSFERRING METAL SHEET PLATES USED IN RECUPERATIVE HEAT EXCHANGERS

摘要

The hot plate packet comprises a number of adjacent profile plates held together but leaving flow channels between them. On at least two opposing packet sides (18, 19) the two outer profile plates (14, 15) are formed as sandwich-type shape-stable profile plate pairs. One profile plate of the pair is undulated and the other is corrugated. The profile plates are joined to one another by welding points (16). The vertical outer rail (20) of the profile plates are connected to horizontal rails (21) on the packet upper and lower sides. The face surfaces of the horizontal rails are located at the same height as the face surfaces of the radial walls of the cells of the hot surface carrier (4).
