HEAT EXCHANGER AND HEAT-EXCHANGER-INTEGRATED OXYGENATOR

摘要

A plurality of heat transfer pipes have a circumferential portion arranged at a short distance from an inner surface of a heat exchanger case while they are bundled to form a pipe group and a first bowstring-shaped portion which retracts toward a center in a direction of cylinder diameter from an arc formed by the circumferential portion. The plurality of bundled heat transfer pipes are loaded in the exchange case such that the first bowstring-shaped portion and an inner surface of the heat exchange case on a side where a heat exchange medium inlet port is attached are opposed to each other. By making a flow of a heat exchange medium to each heat transfer pipe uniform, a heat exchanger capable of obtaining high heat exchange performance is obtained.
