KINETIC HEAT SINK WITH STATIONARY FINS

摘要

A heat-dissipating apparatus has a base structure, a rotating structure, and stationary fins. The base structure has a first heat-conducting surface and a second heat-conducting surface to conduct heat therebetween. The first heat-conducting surface is mountable to a heat-generating component. The rotating structure rotatably couples with the base structure and has a movable heat-extraction surface facing the second heat-conducting surface across a fluid gap. The rotating structure has rotating fins that channels a heat-transfer fluid when the rotating structure rotates from a region of a thermal reservoir in communicating with the rotating structure to another area of the thermal reservoir. The stationary fins extend from the second heat-conducting surface or the housing and are in the path of fluid flow between two areas of the thermal reservoir.
