Abstract:
A computer central processing unit heat dissipater comprising:a) a lower cover having thereon a plurality of fastening tabs and two mounting plates located on opposite ends;b) a plurality of identical, spaced apart first heat sink elements fabricated by a punch press and located on the lower cover between the mounting plates, each first heat sink element having: an upper edge facing away from the lower cover with a concavely curved portion; a hook extending laterally from one side; and a female interlocking slot located such that the interlocking slot of each first heat sink element interlocks with the hook of an adjacent first heat sink element;c) at least one second heat sink element located on the lower cover adjacent to and spaced from one of the plurality of first heat sink elements, the at least one second heat sink element having an upper edge facing away from the lower cover with a concavely curved portion and an interlocking slot engaged by the hook of the adjacent first heat sink element;d) an upper cover having an inverted U-shaped cross-sectional configuration, the upper cover having a plurality of fastening slots engaged with the plurality of fastening tabs and an air flow opening located in alignment with the concavely curved portions of the first and second heat sink elements;e) a fan mounted on the upper cover in alignment with the air flow opening by a plurality of fastening elements extending through fastening holes in the upper cover; and,f) a plurality of recessed sections formed in the upper edge of the first and second heat sink elements, the recessed sections of each heat sink element being aligned with the recessed sections of adjacent heat sink elements and located such that fastening elements extending through the upper cover extend into the recessed portions without deforming the first and second heat sink elements.
