Thermosyphon heat reduction system for a motor vehicle engine compartment

摘要

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.
