Hydraulic friction heat generator
Patent
·
OSTI ID:6036740
A hydraulic friction heat generator filled with hydraulic heat transfer fluid is described which consists of: a cylindrical housing with a central axis through its interior and with end plates generally normal to the central axis, the generator having an inlet conduit means and an outlet conduit means located at opposite ends of the cylindrical housing thereof; a drive shaft bearingly mounted in each of the end plates in coaxial alignment with the central axis and passing through one of the end plates to extend outwardly therefrom; an external power source joined to the extended shaft for rotating the shaft; and smooth-surfaced thin discs with outer generally annular peripheral edges closely-spaced from the inner wall of the cylindrical housing, the discs being fixedly mounted in axially spaced relationship on the drive shaft to be rotated thereby in a single direction, with no stationary elements interposed between the discs, each disc having at least two radially-oriented slits partially transecting the disc to extend inward from the disc peripheral edges, and the discs having a portion of each disc on one side of the slit feathered outward from the plane of the disc to form a vane for turbulently forcing the hydraulic fluid axially toward the outlet conduit means.
