A passive cooling system for aircraft electronics, the system comprising:
- an electronics chassis having a chassis exterior and defining a chassis interior;
- a heat spreader having a body located in the chassis interior;
- a heatsink located in the chassis interior;
- a cold plate operably coupled to the electronic chassis and thermally coupled to the heatsink;
- a first plurality of heat pipes thermally coupled with the cold plate;
- and
- a second plurality of heat pipes thermally coupling the heatsink with the heat spreader.
A method for passive thermal management, the method comprising:
- transferring heat from a heat generating component located in an avionics unit to a heat spreader located within the avionics unit, the avionics unit comprising an electronics chassis;
- transferring heat from the heat spreader to a cold plate operably coupled with the avionics unit;
- and
- transferring heat from the cold plate to at least one of a fuselage, a wing, a skin, or a support structure of an aircraft that is thermally coupled to an external environment outside the aircraft.
