Abstract
A rotary heat exchanger has a plurality of arcuate hollow blow blades with extend between first and second rotating bodies and which conduct liquid from one to the other. Each of the blades is provided with its own set of fins which are arranged to interleave between and overlap those on the adjacent blades. The rotating bodies are constructed to define inlet and outlet chambers therein. Bearings which are disposed between stationary inlet and outlet pipes and the first and second rotating bodies protect seals from damaging forces when the device is rotating.
