<P>PROBLEM TO BE SOLVED: To allow a heat transfer liquid to circulate in an engine, even if the engine or a first pump stops. <P>SOLUTION: An engine cooling circuit includes: a first heat transfer circuit H that is configured so that the heat transfer liquid can circulate through an engine 1, a device 3 where heat exchange is conducted, a first radiator 2, and a first pump 5 that can switch on-off electrically or mechanically; a second heat transfer circuit L configured so that the heat transfer liquid can circulate through an inter cooler 8 of an supercharger, a second radiator 7, a second pump 6 that can electrically switch on-off; and a communication switch mechanism R that switches the heat transfer circuit so that the second pump 6 is serial to the first pump 5 in a portion of the first heat transfer circuit H. <P>COPYRIGHT: (C)2013,JPO&INPIT |
