HEAT EXCHANGER, METHOD FOR MANUFACTURING THE SAME, AND HEART-LUNG MACHINE

摘要

Disclosed is a heat exchanger comprising a plurality of tubes (1) in which a first fluid passes through, a housing (2) for housing the tubes (1), and a sealing member for sealing in a second fluid flowing along the surfaces of t he tubes (1). The housing (2) is provided with an inlet (4) for introducing the second fluid and a first outlet (5) and second outlet (6) for discharging th e second fluid. The sealing member is composed of a first sealing member (3a) arranged on one end side of the tubes (1), a second sealing member (3b) arranged on the other end side of the tubes (1), and a third sealing member (3c) arranged therebetween. The third sealing member (3c) is so arranged tha t a gap (7) is formed between the third sealing member (3c) and the first or second sealing member, thereby forming a channel for the second fluid. The second outlet (6) is so formed as to communicate with the gap (7).
