Abstract
A heat exchanger includes a plurality of tubesthrough an inner cavity of which a heat-transfer medium liquid flows, a sealing memberthat seals the plurality of tubeswhile exposing both ends thereof, with a blood channel passing outside each of the tubesbeing formed in a central portion in the axial direction of the tubes, and a housingthat accommodates the tubessealed with the sealing member. The heat exchanger further includes a hollow fiber membranethat is formed of a plurality of hydrophobic and gas permeable hollow fibersand that is disposed on at least one of an entrance side and an exit side of the blood channel in the housingso that a liquid flowing through the blood channel passes through the hollow fiber membrane. The housingincludes openingsfor exposing open ends of each of the hollow fibersforming the hollow fiber membraneto the outside, and gaps between an inner side of the openings and the hollow fibersare sealed. Air can be removed while suppressing a reduction in the heat exchange efficiency.
