Abstract:
A heat sink assembly for use in transferring and dissipating heat generated by electronic components comprising:a base member formed with a plastic material having a high conductivity factor and an ability to flow into an injection mold; a fin array formed from a single sheet of material and folded into a convoluted shape that incorporates a series of parallel plates through which air can be drawn to dissipate the heat generated from the electronic components, said fin array being over-molded into a top portion of said base member so that said fin array is converted into an integral part of said base member; a heat input portion positionable adjacent to said electronic components and formed on a bottom portion of said base member opposite of said fin array; a heat pipe over-molded into said base member and operably associated with said heat input portion to transfer heat generated by said electronic component to said base member; and a cooling fan mounted to move air across said fin array wherein said base member transfers heat from said heat pipe to said fin array and wherein said fin array is aligned so that air is moved between said parallel plates in a direction generally parallel to a line extending between said heat input portion and said base member.
