Abstract
There is disclosed an engine assembly for an aircraft, including: a combustion engine including a coolant circuit in heat exchange relationship with a heat sink, the heat sink including a heat exchanger and at least one component, the at least one component having a main function that differs from thermal exchange. A method of operating the system is also disclosed.
Claims20
An engine assembly for an aircraft, comprising:
- a combustion engine including a coolant circuit in heat exchange relationship with a heat sink, the heat sink including a heat exchanger and at least one further component of the engine assembly, the at least one further component having a main function that differs from thermal exchange.
A method of operating a heat management system of an engine assembly for an aircraft, comprising:
- circulating a liquid coolant;
- transferring heat from a combustion engine of the engine assembly to a liquid coolant;
- and
- transferring heat from the liquid coolant to an environment outside the engine assembly via both of a heat exchanger and a component whose main function differs from thermal exchange.
A method of operating a heat management system of an engine assembly for an aircraft, the engine assembly including a combustion engine being liquid cooled with a liquid coolant, the method comprising:
- determining that the combustion engine of the engine assembly is off;
- circulating the liquid coolant in a coolant circuit for heating the liquid coolant;
- and
- circulating the heated liquid coolant toward at least one component whose main function differs from thermal exchange for transferring heat from the heated liquid coolant to the at least one component.
