FIELD: machine building. ^ SUBSTANCE: automatic combined micro-processor temperature regulator of power unit of vehicle consists of: source of electric power of alternate current, of control element with sensor of temperature of power unit, with power sensor of power unit, sensor of temperature of open cooling air, sensor of frequency of rotation of cooling fan shaft, of two similar drivers, of three comparing devices, of two asynchronous engines with phase rotors, of source of electric power, of cooling fan, and of mechanism of stator turn of one of engines. The control element is equipped with a device for correction of coefficient of transfer of the temperature regulator by rotation frequency of the cooling fan shaft in accordance with mathematic model of automatic system of temperature regulation in static and in dynamics stored in memory of the control element. The control element is designed for algebraic summing output signals of the temperature sensors of the power unit, the power sensor of the power unit, the cooling open air temperature sensor and for automatic change of coefficient of transfer of the temperature regulator so, that coefficient of transfer of the regulation system stays constant in a specified range of the change of power of the power unit, temperature of open cooling air and rotation frequency of the cooling fan. The said elements and structure design of asynchronous engines correspond to the disclosed invention. ^ EFFECT: raised reliability and reduced expenditures for cooling. ^ 9 dwg |
