Title:
PLATE TYPE HEAT EXCHANGER FOR THREE FLUIDS AND METHOD OF MANUFACTURING THE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2000/034729
Kind Code:
A1
Abstract:
A plate type heat exchanger for exchanging heat between a first fluid and second and third fluids in that order, wherein the part of a laminated plate material body near its one end side in the plate material laminating direction is formed in a front stage heat exchange part (13A) in which first plate-to-plate fluid paths (f1) allowing a first fluid (La) to pass and second plate-to-plate fluid paths (f2) allowing a second fluid (Lc) to pass are positioned between plate materials alternately to each other in the plate material laminating direction, the part of the laminated plate material body near its other end side in the plate material laminating direction is formed in a rear stage heat exchange part (13B) in which first plate-to-plate fluid paths (f1) allowing a first fluid (La) to pass and third plate-to-plate fluid paths (f3) allowing the third fluid (Lb) to pass are positioned between the plate materials alternately to each other in the plate material laminating direction, and a crossover path (m) leading the first fluid passed through the first plate-to-plate fluid path of the pre-stage heat exchange part into the first plate-to-plate fluid paths of the rear-stage heat exchange part is provided.
