Goncharov A. Increasing of technican-working features of the car by perfection of the block "radiator-ventilator" of engine's cooling system.

Object of investigation is working processes of heat transmission and aerodynamics in the block "radiator - ventilator" of cooling device of car's engine. Subject of investigation is conformities to the law of influencing of construction's parameters and modes of operations on the working processes of heat transmission and aerodynamics in the block "radiator - ventilator" of the cooling system of car's engine. Were used: method of systems analysis, method of thermal balance and mathematical design, method of numeral integration, analytical method of the system of differential equalizations with the use of experiment, method of the mathematical planning of experiment, theory of similarity, method of technical - economic analysis. Scientific novelty - the investigation of orebreniya degree on power descriptions of the radiator has got further development; the model of heat exchange in the radiator; power descriptions of aluminium radiators, have been first experimentally investigated, and aerodynamic descriptions of cars' ventilator options. Practical value: the method has been specified and the program of calculation of the block "radiator - ventilator" ; recommendations on the choice of rational parameters of the construction and modes of operations of the block "radiator - ventilator" of the cooling systems of passenger cars' engines have been developed and accepted into the application. Sphere of application: it can be used in project - design departments of motor industry enterprises; in scientific - research organizations.
