FIELD: engines and pumps.
SUBSTANCE: fluid heating device comprising a pump, a pipeline connected to the pump and providing communication along fluid medium from the pump, and a hole in the pipeline. While using the pump contains a fluid medium. The first part of the fluid medium is pumped into the pipeline, and the second part of the fluid medium remains in the pump. The hole limits the flow of the fluid first part in the pipeline. The second part of the fluid medium is heated in consequence of friction between the second fluid medium part and the pump. A method of a fluid medium heating is also described.
EFFECT: increased efficiency, reduction of fuel consumption.
