A study on the improvement of heat exchanging efficiency of a disposable rotating disc type oxygenator

Abstract

This is to improve the heat-exchanging efficiency of a disposable disc type oxygenator, which was reported in 1979. The oxygenator is made of two doubled cylinders. The inner cylinder, in which the rotating discs are installed, is the oxygenator and around of it, the outer cylinder is arranged as the heatexchanger like a water jacket. Every part of the oxygenator is made of plastic material. To obtain high heat-exchanging efficiency, an alminum plate was fixed at the bottom of the oxygenator, where the plastic wall was partially cut out. Instead of the plane plate, waveform alminum plate showed the most favorable heat-exchanging effect.
