CONTROL METHOD OF INTERNAL COMBUSTION ENGINE COOLING SYSTEM Russian patent published in 2009 - IPC B61C5/02 B60K11/02 

FIELD: engines and pumps.

SUBSTANCE: invention refers to transport means, and namely to cooling systems of internal combustion engines of traction equipment. Control method of the cooling system consists in the fact that fans draw in the cooling air through radiator sections with hot heat carriers of cold loop, which are installed in the first row, and of hot loop, which are installed in the second row, in the direction of the cooling air movement, and control the temperatures of hot heat carriers of hot and cold loops owing to change of fan rpm. When hot heat carrier temperature is decreased in cold loop below allowable level, not less than one fan is switched over to reverse mode, cooling air is subsequently blown with the fan switched over to reverse mode to some part of radiator sections of hot loop, and then to some part of radiator sections of cold loop in order to decrease heat transfer from hot heat carrier of cold loop. At that, there partially used is heated cooling air of the fan working in suction, which has passed through some part of radiator sections of cold and hot loops, in the cooling air blown in with one or several fans switched over to reverse mode.

EFFECT: providing the possibility of temperature control of hot heat carrier of hot and cold loops of the cooling system in the whole ambient temperature range and decreasing temperature tensions in front rows of radiator tubes.
