ABSTRACT:
A viscous fluid type heat generator including a drive shaft for receiving a rotative drive force from an external drive source and mounting thereon a plurality of rotor elements to be rotated together with the drive shaft, a housing assembly in which at least one first heat generating component chamber confining therein a heat generative viscous fluid to which a shearing action is applied by the rotor elements, a second heat-generating-performance variable chamber confining a heat generative viscous fluid to which shearing action is applied by the rotor element, and a heat receiving chamber in which heat exchanging liquid flows therethrough to receive heat from the first and second heat generating chambers. The viscous fluid type heat generator further may includes a control chamber for controlling an amount of the viscous fluid in the second heat-generating-performance variable chamber, and a heat-generating-performance changing unit.
