FIELD: machine building.SUBSTANCE: invention relates to machine building, namely to cabin heating systems in all types of vehicles: ground surface, water surface, underwater and air ones driven by internal combustion engines (ICE) of all types operating on liquid and/or gaseous fuel, with fluid or air cooling, with the number of cylinders of at least two, two- and four-stroke ones. Thermal power unit for a vehicle contains air ducts (8, 9) and intake pipes (4) and is made in the form of a gas-air heat exchanger, on one side connected directly to the ICE of the vehicle, and on opposite side to system (10) of exhaust gases discharge. In housing (1) of the gas-air heat exchanger there are intake pipes (4) equipped with turbulators (7) connected to ICE exhaust gases channels. Between intake pipes (4) there are partitions (6) to create a countercurrent motion of the heated air to the exhaust gases movement.EFFECT: higher efficiency of using heat energy of exhaust gases.1 cl, 2 dwg |
