Patent ID: 7273091

Claim:
A cooling apparatus comprising: fan means for creating an air flow including a plurality of disk fan elements spaced apart in a stack configuration and adapted for rotation to create said air flow; multiple heat sink means surrounding said plurality of disk fan elements; a heat distribution block for receiving heat generated from a heat generating device; a plurality of heat pipe elements communicating with said heat distribution block and said multiple heat sinks, said heat distribution block and heat pipe elements transferring heat from said heat generating device for distribution to said heat sinks; a motor drive means for rotating said plurality of disk fan elements, said motor drive means including a shaft means for mounting said plurality of disk fan elements in said stack configuration, said shaft means comprising a hollow shaft, said motor drive means being integrated in the shaft means; and, at least one radial element located in spaced apart relation on each disk fan element and positioned between adjacent disk fan elements to form air gaps between said disk fan elements; wherein said plurality of disk fan elements are rotated to create an efficient, less turbulent air flow in an outward direction such that heat is uniformly eliminated from said surrounding multiple heat sink means.
