ELECTRIC GENERATOR WHICH UTILIZES IMPELLER

摘要

Disclosed is an electric generator which utilizes an impeller rotated by a two-phase heat transfer fluid which circulates between a heat source part and a heat sink part. The impeller (23) is configured with a rotating axle (23a) located at the center of rotation thereof, which rotates and supports said impeller (23); a cylindrical runner (23b) fixed to said rotating axle (23a); and a plurality of wing-shaped buckets (23c) disposed around the aforementioned rotating axle (23a) at a radiating angle. Said impeller (23) is structured to rotate at low torques, and a check valve is installed at an appropriate location to prevent reversed rotation. A rotating electric generator element (23d) is fixed to the aforementioned rotating axle (23a), and has the ability to generate electricity when the impeller (23) rotates by means of the flow of heat transfer fluid (26).
