Abstract: A heat exchanger system may have a base, a mounting apparatus for attaching the base to a device, a gasket shelf for placing a gasket, a dissipation member for dissipating heat, and heat generator attachment sites for absorbing heat. A mounting apparatus may have finger-like extensions which flex and draw the base into contact with an underlying electronic device from which the system conducts heat. A base may also have an integrated heat pipe clamp attachment forming an aperture in the base into which a heat pipe may extend and may be clamped in thermal communication. The dissipation device may be a series of fins and troughs and a fan may direct air over the dissipation device to cool the apparatus.

Abstract: An electronic flight bag computer (EFB) includes a housing defining first and second compartments that are fluidly isolated from and in thermal communication with one another. The first compartment contains electronic components connected to a user interface on an exterior portion of the housing for providing interactive flight related computation functions to a user. The second compartment contains a forced convection cooling component in thermal communication with the electronic components. The forced convection cooling component directs a flow of cooling fluid into the second compartment to convey heat produced by the electronic components out of the housing, such that the cooling fluid in the second compartment remains fluidly isolated from the electronic components in the first compartment of the housing.
