  • Heat sink for dissipating heat generated by electronic displays
    Patent number: 4574330
    Abstract: An article for dissipating heat generated by an alphanumeric display which is mounted on an electronic circuit board. The article includes a heat sink which is coupled to the underside of the alphanumeric display. The heat sink has at least one transfer member which extends through the electronic circuit board and is coupled to a dissipation plate. The dissipation plate is exposed to an environment which is removed from the immediate environment of the electronic circuit board. Heat generated by the alphanumeric display is transferred to the heat sink and through the transfer member(s) to the dissipation plate. The heat is then dissipated in an environment which is removed from that of any electronic components mounted on the electronic circuit board.
