ABSTRACT:
A viscous fluid type heater is disclosed. The heater has a front housing and a rear housing secured to each other. The front housing has a space in which a first partitioning plate and a second partitioning plate located immovably fitted. A heating chamber that is defined between the first plate and the second plate accommodates viscous fluid. A rotor is rotatably supported in the heating chamber. The rotor rotates and shears the viscous fluid to generate heat. A heat exchange chamber is defined by the first and the second partitioning plates and disposed adjacent to the heating chamber. The heat exchanging chamber allows circulating fluid to flow therethrough so that the circulating fluid is heated by the heat transmitted to the heat exchanging chamber from the heating chamber. A securing structure secures the partitioning plates to the housing and concaves are formed in the outer peripheral surface of the partitioning plates to decrease a contacting area of the outer peripheral surface and the inner peripheral surface.
