Abstract:
A viscous fluid type heater comprising a heating chamber, a rotatable rotor within the heating chamber, and a heat exchange chamber, the heat exchange chamber being located adjacent to the heating chamber, said heating chamber for accommodating viscous fluid and said rotor for shearing the viscous fluid to produce heat, said heat exchange chamber allowing circulating fluid to flow therethrough, wherein the heat is transmitted to the heat exchange chamber from the heating chamber to heat the circulating fluid, said heater further comprising:a reservoir chamber communicating with the heating chamber for providing an auxiliary reservoir for the viscous fluid;a partition plate for defining in part the heating chamber and the reservoir chamber, the partition plate having a through hole for communicating the heating chamber with the reservoir chamber, wherein the partition plate is independent of the rotor and faces the rotor;stirring means for stirring the viscous fluid in the reservoir chamber; anda drive shaft carrying the rotor thereon, said drive shaft having a portion extending through said partition plate and into the reservoir chamber to provide at least a part of the stirring means for stirring the viscous fluid in the reservoir chamber.
