Abstract
A system (10) and method for removing heat from an engine compartment in a motor vehicle where heat generated by operation of a heat engine (12) that propels the vehicle tends to collect. Engine heat is collected in a thermofluid in a reservoir forming an evaporator (14) where the thermofluid absorbs heat sufficient to evaporate it. The vapor naturally migrates to a condenser (22) that is cooled sufficiently to condense the vapor back to liquid phase. The liquid falls by gravity back to the condenser.
Claims7
A motor vehicle comprising:
- a chassis supporting an engine compartment, in the engine compartment, a heat engine that propels the motor vehicle;
- a thermosyphon system comprising
- a collector that collects heat generated by running the heat engine and transfers that collected the heat to the thermofluid, a dissipator connected by conduits to the reservoir, wherein, upon heating, the thermofluid circulates to the dissipator to reject heat from the thermofluid and then for thermofluid and back to the collector to collect more heat, the thermofluid circulating via a reservoir disposed inside the engine compartment, the reservoir being in overlying relation to the heat engine, and wherein the collector is disposed to heat thermofluid in the reservoir.
