SET OF HEAT EXCHANGER Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: this heat exchanger is intended for carrying out processes of heat exchanging between two media through wall in chemical, food, and oil processing enterprises. Device includes strips assembled in set and secured over end-faces by distributing boards. Strips are assembled in set through sealing members. Steps are made at distance l equal to 5-10% of length L of set. Depth H of steps is equal to 1.0-1.5 of width S of sealing ring. Strips are welded into pairs to form separate cases through sealing members which on section of steps repeat configuration of strips. Protrusions are made in strips in the form of part of sphere or cylinder or wave. Application of aforesaid embodiment of heat exchanger set allows for maximal utilization of useful volume of heat exchanger and can be used in various casings of heat exchangers. EFFECT: higher efficiency. 1 cl, 2 dwg
