ABSTRACT:
A notebook computer has a base and a cover that is pivotally mounted to the base with a hinge. An integrated circuit chip is mounted to the base and has one end of a heat pipe attached to it or to an associated heat dissipation device. The other end of the heat pipe lies along the hinge. A spreader plate is mounted in the cover and attached to the other end of the heat pipe to form a nested, rotational joint. One end of the plate is located along the hinge and formed into a slotted cylinder. The heat pipe is pressed into the slot to form the joint which is tight around the heat pipe, but still allows it to rotate to accommodate the pivot motion of the cover. A retainer may be incorporated into the design to further enhance the strength of the joint and assure thermal continuity. The retainer is a hollow cylinder with an axial slit through which the plate extends.
