ABSTRACT:
Improved structure for cooling the rotor of a rotary engine wherein a heat pipe structure is provided extending inwardly from an outer portion of the rotor for transferring heat inwardly to a heat transfer structure within the rotor. Heat is transferred through the heat transfer structure from the heat pipe to lubricant coolant flowed through a grooved wall inwardly of the heat pipe and outwardly of the rotor bearing. In the illustrated embodiment, the heat pipe is provided with a body of water for effecting the desired heat transfer from the rotor apex.
