Abstract

Disclosed is a concept relating to a heat sink for an option card. This new heat sink has a bracket that conforms to the standardized regulation of the option cards. This new heat sink brings heat from the option card, not only to the surrounded air by itself, but also to the external of a computer housing by the option card's Bracket.

Option Card Heat Sink Merged with Card Bracket

      Disclosed is a concept relating to a heat sink for an option
card.  This new heat sink has a bracket that conforms to the
standardized regulation of the option cards.  This new heat sink
brings heat from the  option card, not only to the surrounded air by
itself, but also to the  external of a computer housing by the option
card's Bracket.

      The Figure shows the comparison of a new concept heat sink and
a conventional heat sink.  Of course, the new concept heat sink works
at least as well as the conventional heat sink.  In addition, the new
one can bring heat to the outside of the computer housing as
described above and can be understood by looking at the Figure.  This
heat sink also reduces the number of parts and total parts cost.
Because it can  be made as a single part, on the other hand, the
conventional design needs at least two parts: a heat sink and a
bracket.  Therefore, the present invention realizes high heat
transfer performance and cost reduction at the same time.

      This concept is not limited to the option cards of the
computer.  Any device which needs a heat sink and has a mechanical
bracket is also applicable.
