PCT No. PCT/GB90/00675 Sec. 371 Date Nov. 5, 1991 Sec. 102(e) Date Nov. 5, 1991 PCT Filed May 2, 1990 PCT Pub. No. WO90/13784 PCT Pub. Date Nov. 15, 1990.A heat exchanger including a plurality of fluid pathways (13, 15, 16, 17, 18) in which at least some are defined between surfaces of unperforated primary plates (10). Between the primary plates (10) are at least two secondary perforated plates (12) extending along the fluid pathway (13, 15, 16, 17, 18) with perforations (11) in adjacent plates (12) being staggered. Adjacent secondary (12) and primary (10) sheets are in contact such that conducting pathways (19) are formed extending between the two primary surfaces while areas of secondary plates (12) not in contact with other secondary plates (12) constitute secondary surfaces (22). |
