Patent number: 7603977Abstract: The invention relates to a cooling duct piston for an internal combustion engine comprising heat pipes. In order to improve dissipation of heat from the thermally loaded piston areas while preventing thermal tensions, liquid-filled heat pipes that are provided with an evaporator end and a condenser end are disposed in bores of the cooling duct which are oriented towards the bottom of the piston. The heat pipes are arranged such that the evaporator ends terminate at the end of the bores which faces the piston bottom while the condenser ends terminate in the closed cooling duct.Type: GrantFiled: August 10, 2005Date of Patent: October 20, 2009Assignee: Mahle International GmbHInventors: Peter Heidrich, Roland Lochmann, Timo Estrum

Patent number: 7549368Abstract: The invention relates to a lightweight piston comprising heat pipes. The aim of the invention is to simplify the structure of such a piston while at the same time allowing for an improved heat dissipation from the piston areas subject to heat load while avoiding thermal stress. For this purpose, a plurality of liquid-filled heat pipes each having an evaporator and a condenser end is used, whereby the evaporator end is configured by short pipe sections that are oriented in the thickness at bottom towards the focal point and that are interlinked by means of a composite heat pipe extending in parallel to the piston head. At least two pipe sections functioning as the condenser end are coupled with the composite heat pipe in such a manner as to configure, by way of a pipe connection arranged on the condenser ends, a closed coolant cycle between the evaporator end, composite heat pipe and condenser end of the heat pipe.Type: GrantFiled: August 10, 2005Date of Patent: June 23, 2009Assignee: Mable International GmbHInventors: Peter Heidrich, Roland Lochmann, Klaus Keller
