TEMPERATURE CONTROL OF HEAT CARRIERS OF THERMAL MACHINE Russian patent published in 2012 - IPC F01P7/00 

FIELD: machine building.

SUBSTANCE: temperature control of heat carriers of thermal machine, which contains water and oil temperature converters, electropneumatic valves controlling the air supply to pneumatic cylinders of opening of louvers of oil and water cooling loops, automatic actuator of hydraulic coupling of variable filling of fan drive, fan of cooling chamber, louvers of water and oil cooling loops, is equipped with microprocessor controller connected by means of its inputs to outputs of water and oil temperature converters, the first and the second outputs of microprocessor controller are connected to inputs of electropneumatic valves, and the third output of microprocessor controller is connected to input of actuating mechanism of control of automatic drive of hydraulic coupling of variable filling of fan drive; at that, microprocessor controller includes calculation units of rate of change of cooling oil and cooling water temperature, two adders, two threshold devices, two comparison units, four reference units and maximum assignment unit.

EFFECT: increasing economy and improving operating reliability of thermal machine owing to improving accuracy and reducing the value of temperature fluctuations of cooling oil and water.
