DEVICE FOR PRESTART WARM-UP OF AUTOMOTIVE ICE Russian patent published in 2009 - IPC F02N17/06 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production, particularly to liquid-type cooling systems. Proposed device comprises jacket, radiator, pump, silencer with pipe and thermal relay. In compliance with this invention, heat accumulator is connected to exhaust gas pipeline 3 with lengthwise axis 40 of heat exchanger 41 aligned with lengthwise axis of aforesaid pipeline 3. Note here that sealed space between two walls 43 and 44 of cylindrical heat exchanger 41 is filled with heat accumulating substance 7. Note also that ID of through channel 31 of heat exchanger 41 equals that of aforesaid pipeline 3, while outer surface of aforesaid cylindrical heat exchanger 41 stays in contact with working fluid in space 35 of heat exchanger of heat accumulator 6. Suction float 30 closes electric contacts 22 when coming in contact with diaphragm 21. Expanding tank 24 is arranged above radiator top tank cooling system jacket and heat exchanger 6. Note that inner space 35 of heat exchanger 6 communicates via float-type valve 36, pipeline 28, expanding tank 24 and metered orifice with atmosphere.

EFFECT: ICE waste gas heat recovery.
