Heat generating apparatus employing viscous fluid

摘要

A heat generating apparatus having a housing assembly in which a working chamber including a heat generating region for heat generation and a fluid storing region for storing a viscous fluid, and a heat receiving chamber for receiving heat from the heat generating region are formed. The heat generating apparatus also having a rotor element mounted on a drive shaft to be rotated within the working chamber to apply a shearing action to the viscous fluid within the heat generating region. The viscous fluid generates heat when the shearing action is applied thereto so that the heat is transmitted to a heat exchanging liquid flowing through the heat receiving chamber. The heat generating region and fluid storing region communicating through an aperture formed in a partition wall formed in the working chamber, and the aperture having a gas-phase portion, a liquid-phase portion and a liquid supply portion.
