Special Challenges In 3D Simulations of Graphite Heat Spreaders
INTRODUCTION Graphite is a naturally occurring form of pure carbon in which the atomic bonds interlock in the layers of a two-dimensional molecular sheet. In nature, dense, rigid graphite ore is mined, purified, and processed into numerous applications, including the inexpensive flexible natural graphite sheets used in electronics. The ore is mechanically reduced and then … [Read more...]
Managing Cooling Fan Noise In Product Design
ABSTRACT Cooling fan noise is a system property determined as much by thermal and mechanical design and fan selection as by a fan’s acoustical design. While even the quietest fan can be used in a noisy manner, a significant fraction of unpleasant surprises can be avoided. NOMENCLATURE C Numerical constant D … [Read more...]
