Embodiment Construction

[0030] In an illustrative embodiment, the kinetic heat sink has intersecting fins between its stationary and rotating parts to create radial heat transfer - additionally or alternatively, axial heat transfer. The inventors have surprisingly found that such a dynamic heat sink does not require the precise and complex tolerances of prior art dynamic heat sinks which rely primarily on axial heat transfer. Specifically, although the crossed fins introduce more critical surfaces than a single axial surface, the crossed fins allow for greater clearance. Advantageously, these larger gaps are easier to control since radial outflow is generally more controllable than axial outflow. Thus, in many of these embodiments, standard manufacturing equipment and techniques can produce more efficient kinetic heat sinks. Furthermore, with this innovation, the stationary and rotating parts can transfer waste heat more efficiently without increasing the overall equipment footprint. Thus, a kineti...

Abstract

A kinetic heat sink has a stationary portion with a first heat-conducting surface and a second heat-conducting surface to conduct heat therebetween. To cool heat generating devices devices, the stationary portion is mountable to a heat-generating component and has a first plurality of fins extending therefrom. The kinetic heat sink also has a rotating structure rotatably coupled with the stationary portion. The rotating structure is configured to transfer heat received from the second heat-conducting surface to a thermal reservoir in thermal communication with the rotating structure. The rotating structure has a movable heat-extraction surface with a second plurality of fins extending toward the first plurality of fins. At least a portion of the first plurality of fins preferably are interdigitated with at least a portion of the second plurality of fins.

Description

[0001] priority [0002] This application claims priority to U.S. Provisional Patent Application 61 / 868,362, filed August 21, 2013, which is hereby incorporated by reference in its entirety, and entitled "Having Concentric Cross-Transfer A Dynamic Heat Sink for Thermal Fins", inventors Lino A. Gonzalez and Steven J. Stoddard. technical field [0003] The present application relates generally to rotary heat sinks and heat sinks, and more particularly, the present invention relates to powered heat sinks for use with electronic components. Background technique [0004] During operation, circuits and electrical devices generate waste heat. In order to function properly, the temperature of circuits and electrical devices usually must be within certain limits. To this end, the temperature of the electrical device is typically controlled using a heat sink physically mounted near or on the electrical device. [0005] A relatively new type of heat sink assembly known as a "kinetic...
