<p>PURPOSE:To obtaifn a blower of a high efficiency and free of clogging or the like with a simple construction by forming an impeller of a blower by a corrugated metal plate, and causing two different operating fluids to both surfaces to perform heat exchange between both fluids. CONSTITUTION:When the blower is rotated by the rotation of a main shaft 13, two air streams 7 and 8 are generated at grooves 9 and 10 of both surfaces of the impeller 2. These air streams 7 and 8 become streams adjacent to each other through the wall surface of the impeller 2. Since outside blind plates 5 and 6 exist, two air streams 7 and 8 are not mixed, and completely separate at both surfaces of the blower. When a temperature difference is produced between two air streams 7 and 8 in this state, the heat exhcnage is performed through the wall surface of the impeller 2, and the air stream on the high temperature side loses its calory to lower the temperature and the low temperature side is supplied with the calory and the temperature rises.</p> |
