According to one embodiment of the invention, a cooling system for a heat-generating structure comprises a chamber and structure disposed within the chamber. The chamber has an inlet and an outlet. The inlet receives fluid coolant into the chamber substantially in the form of a liquid. The outlet dispenses the fluid coolant out of the chamber at least partially in the form of a vapor. The structure disposed within the chamber receive thermal energy from the heat generating structure and transfers at least a portion of the thermal energy to the fluid coolant. The thermal energy from the heat-generating structure causes at least a portion of the fluid coolant substantially in the form of a liquid to boil and effuse vapor upon contact with a portion of the structure. The effusion of vapor creates a self-induced flow in the chamber. The self-induced flow distributes non-vaporized fluid coolant substantially in the form of a liquid to other portions of the structure.

System and method of boiling heat transfer using self-induced coolant transport and impingements

A heat-conducting device for conducting heat between a circuit board and an airframe of a missile includes a thermal plane onto which the circuit board is mounted, and a pair of feet that partially protrude from the slots in the thermal plane. Slot-engaging portions of the feet freely float within the slots, allowing repositioning of the feet in two dimensions relative to the slots. Resilient devices such as springs urge outer portions of the feet into contact with the airframe. Locking mechanisms may prevent extension of the feet until after the heat-conducting device is installed in the missile. The feet self-align into contact with the airframe, automatically adjusting to compensate for misalignment and/or warping.

Heat-conducting device for circuit board

A heat conducting device for providing a thermal path between a circuit board and a missile airframe includes a thermal plane that is adapted to receive a circuit board and a collar that encompasses at least a portion of the thermal plane. The collar has a first position that disengages the heat conducting device from at least a portion of the airframe and a second position that engages the heat conducting device with at least a portion of the airframe to provide a thermal path between the circuit board and the airframe.
