Abstract
Abstract A fan heatsink assembly is provided to afford cooling for electronic components mounted on a circuit board. The assembly includes a blower mounted on top of a specially shaped heatsink, the heatsink having a truncated hyperbolic shaped central member, with fins radially emanating from the center. The blower draws air in through the area between the fins, up the curved central portion and into the blower assembly where it is then exited out the sides of the fan. The fins may be smooth or textured, straight or curved. The fan heatsink assembly is attached to the device to be cooled. Heat is transferred from the electronic component, into the heat dissipating member where the fan causes air to be drawn up between the fins and along the curved center portion, removing heat from the heat dissipating member and the electronic component.
