PCT No. PCT/GB92/00301 Sec. 371 Date Aug. 23, 1993 Sec. 102(e) Date Aug. 23, 1993 PCT Filed Feb. 20, 1992 PCT Pub. No. WO92/15829 PCT Pub. Date Sep. 17, 1992.A plate-fin type of heat exchanger facilitates exchange of heat between two process streams such as high pressure methane and seawater and includes a matrix of heat exchange plate elements arranged side-by-side, flow passages for the seawater process stream being defined between adjacent plate elements. The plate elements are a high-integrity diffusion bonded sandwich construction comprising two outer sheets and a superplastically expanded core sheet structure between the two outer sheets. The sandwich construction provides flow passages for the methane process stream. Adjacent plate elements are held in position relative to each other by serrated bars or racks which engage the edges of the plate elements. |
