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.

A method of producing a heat exchanger includes designing the heat exchanger to include a wall with a target thickness. A model is created relating process parameters to geometry of a single track melt pool and relating the single track melt pool geometry to a heat exchanger wall thickness. At least one variable process parameter is defined. The model, heat exchanger wall target thickness, and variable process parameters are used to identify a set of process parameters to produce the heat exchanger wall target thickness. The melt pool geometry is predicted based on the model and process parameters. The heat exchanger wall target thickness is predicted based on the melt pool geometry. The process parameters that will produce the heat exchanger wall target thickness are identified. The additive manufacturing process is controlled based upon the identified set of process parameters to create the heat exchanger wall target thickness.
