VEHICLE HEAT GENERATOR AND VISCOUS FLUID THEREFOR

摘要

A non-Newtonian fluid (for instance, a specific silicone oil) having a tendency that the apparent viscosity decreases as the shearing speed of a rotor (33) increases is used as a viscous fluid (F) that is contained in a vehicle heat generator provided with the rotor (33). The nominal viscosity of the viscous fluid (F) ranges from 10,000 cSt to 200,000 cSt. By using the viscous fluid, the shearing heat generating function of the viscous fluid (F) can be maintained for a long time even when the viscous fluid bears excessive shearing due to excessive rotation of the rotor (33), and the rotor (33) can be easily activated from the stationary state at a lower temperature.
