Abstract:
Graphics card apparatus with improved heat dissipation, comprising:a generally planar heat conducting cover plate for connection to a graphics card assembly; a plurality of thermal transfer means for selective affixation to sources of thermal energy on the graphics card assembly and adapted to be thermally coupled to said cover plate; and a fan and carrier therefor including a heat sink and flow directing vanes thermally coupled to and carried by said cover plate, said heat sink thermally engaging the GPU of the graphics card assembly, said vanes being configured to direct air from said fan toward said thermal transfer means; whereby thermal energy generated by the active board elements of the graphics card assembly is transferred to the thermal transfer means and fan carrier, sinked to the cover plate and ultimately removed from said thermal transfer means and cover plate by an air flow drawn into said flow directing structure and exhausted through said vanes.
