Patent number: 5117903Abstract: A multitube heat exchanger is used as a heat exchanger for blood in an artificial lung, for example. The multitube heat exchanger has a number of pipes disposed in a tubular housing and heads mounted on the opposite ends of the housing and having fluid inlet and outlet ports, respectively. A fluid flows through the pipes. The housing has fluid inlet and outlet holes for passing another fluid around the pipes. One of the heads which has the fluid inlet port accommodates baffle plates for checking the fluid flow to produce a turbulent fluid flow. With this arrangement, no air bubbles remain trapped in the head with the fluid inlet port, and the fluid can uniformly distributed into the pipes to keep a uniform temperature within the heat exchanger.Type: GrantFiled: March 12, 1990Date of Patent: June 2, 1992Assignee: Terumo Kabushiki KaishaInventors: Hiroaki Oshiyama, Atsuhiko Nogawa, Satoru Sakai
