An apparatus for heating a liquid comprising a housing having an internal chamber and a rotor disposed in said chamber. A drive shaft rotatably supported in the housing and extending into said chamber for imparting mechanical energy to the rotor. The rotor having a generally hemi-spherically shaped form and provided with a series of openings. A fluid intake passage in said housing preferably arranged to be nearer the rotational axis of the rotor and a fluid exit passage preferably positioned radially outwardly of said rotor.

The apparatus has a housing with a main chamber in which a rotor is situated. A drive shaft drives the rotor about a longitudinal axis of rotation. The housing has a fluid inlet and a fluid outlet, the fluid inlet communicating with an inlet region and a fluid outlet communicating with an exit region. The outer surface of the rotor forms one boundary for the fluid heat generating region and is confronted by the inner surface of the main chamber which is the other boundary. At least one of these surfaces is angularly inclined relative to the axis of rotation of the drive shaft and rotor. By bodily shifting the rotor in a direction along the longitudinal axis, an increase or decrease in the distance between the outer and inner surfaces is possible in order to adjust for wear or to change the degree of shear experienced by the passing fluid.

A preferred embodiment supplemental heating system is fluidly connectable to a vehicle cooling system and includes a liquid heat generator operable for heating a cooling fluid delivered to the supplemental heating system from the vehicle's cooling system.

A system and method for processing a fluid, including decontaminating water and generating water vapor includes introducing the fluid into a vessel. The fluid is moved through a series of rotating trays alternately separated by stationary baffles so as to swirl and heat the fluid to effect the vaporization thereof to produce a vapor having at least some of the contaminants separated therefrom. The vapor is removed from the vessel for condensing apart from the separated contaminants and the remaining water. The vapor may be passed through a turbine connected to an electric generator. Sensors in a controller may be employed to adjust the speed of rotation of the trays or fluid input into the vessel in response to the sensed conditions. The treated fluid may be recirculated and reprocessed through the vessel to increase the purification thereof.

A fluid-charged heating device comprising a cylindrical housing in fluid communication with a housing extension; a cylindrical rotor disposed centrally and mounted for rotation in said cylindrical housing in spaced relation to provide an annular passage for heat transfer fluid to recirculate between the cylindrical housing and the housing extension. The rotor has a surface with a continuous helical groove along the longitudinal axis of the rotor and rotation of the helically grooved rotor causes fluid shearing, heat-generating cavitation, and recirculation of the heat transfer fluid between the housing and the housing extension.

A method and steam generator includes a steam generator container having a heated wall surface, an inlet for a liquid and an outlet for removing the vaporized liquid or steam, a rotor, which is mounted for rotation in the container and causes a rotational flow of the liquid outwardly against the heated wall to cause vaporization. During rotation of the rotor, outer edges of the blades of the rotor contact the wall surface to either abrade or wipe deposits, such as lime, from the wall surface.

A heating apparatus for a vehicle includes a pump for circulating cooling water in a cooling water circuit, a heating heat exchanger for heating air blown into a passenger compartment of the vehicle using cooling water as a heating source, and a throttle valve disposed at a discharge side of the pump. In the heating apparatus, when the temperature of cooling water is low and heating capacity for heating the passenger compartment is insufficient, an opening degree of the throttle valve is reduced by a control unit. Therefore, heat is generated from the throttle valve and the pump so that the temperature of cooling water is increased. Thus, heating capacity of the heating apparatus can be improved without using a manual operation.

The invention relates to a heating device, in particular for motor vehicles, for generating frictional heat by liquid friction with a housing which is arranged in a stationary position and has a working space and a motor-driven rotor in the working space.

A system for supplying supplemental heat to a vehicle, particularly a vehicle with a diesel engine, A driven viscous plate with different viscous clutch faces on either side is provided between the engine and the coolant pump. One side clutches to the engine structure (ground) to generate heat, and the other side clutches to the coolant pump to vary the pump drive. The two sides are controlled by a valve operated by signals from the engine computer. The valve varies the supply of viscous fluid from a common reservoir independently to both sides of the driven viscous plate. The signal from the engine control unit is based on the instantaneous desired supplemental heat and coolant flow. In another embodiment, two separate viscous clutches are utilized and positioned on opposite sides of the coolant pump.

According to the boiler, when the water moves axially along the water flowpath and contacts with the outer circumferential face of the rotary body so as to greatly increase friction distance, and friction efficiency is maximized by the sunken holes. In addition, by means of the grooves, the water is flowed smoothly in the housing, and the water is easy to be sucked, discharged and circulated with an external circulating system by using self suction.
