20100002742 | Rotary Disk Module - There is provided a rotary disk module to efficiently transfer heat from a rotatable disk to a stationary heat sink. The rotatable disk is in proximity of the heat sink with a small gap that allows the disk to move, and which is filled with a cooling medium. The cooling medium aids in transfer of heat from the rotatable disk to the heat sink by conduction, convection, evaporation and other heat transfer means. The heat may be deposited on a portion of the rotatable disk on which an optical beam is being incident or from which an optical beam is generated or both. The rotary disk may be fabricated from various materials depending on the intended applications of the module, and the heat sink is preferably fabricated from materials with high thermal conductivity. The disk may be mounted on a disk-mounting surface that provides for a gap between the rotatable disk and the heat sink surface. The disk-mounting surface is in turn connected to a mechanism for rotating the disk in a smooth fashion. There are provided mechanisms to adjust the gap thickness and the gap uniformity. | 01-07-2010 |
