Introduction In 1995, a typical thermal design engineer was aware that removing heat was not going to get any easier in the next few years. A look back at the past ten years reveals that thermal management remained a challenging field. Fortunately, developments and improvements in thermal management hardware have assisted the electronics packaging community by enabling higher … [Read more...]
Threatened With a Pipe
I have become a Heel Dragger. When natural convection was all the rage, I was touting fans. Once fan cooling became the status quo, I started dropping hints about heat pipes and thermoelectric coolers. The technology roadmap showed nothing but higher power ahead, and I would soon need those fancier cooling tools. Now everybody senses that this air cooling act is growing stale, … [Read more...]
Low Profile Heat Sink Cooling Technologies for Next Generation CPU Thermal Designs
Introduction The electronic industry requires increased forced-air cooling limits to cool high-end server CPUs adequately. Improving air-cooled heat sink thermal performance is one of the critical areas for increasing the overall air-cooling limit. One of the challenging aspects for improving heat sink performance is the effective utilization of relatively large air-cooled fin … [Read more...]
Use Of Heat Pipe Cooling Systems In The Electronics Industry
Introduction Thermal management of electronic components must solve problems connected with the limitations on the maximum chip temperature and with the requirements on the level of temperature uniformity. To cool electronic components, one can use air and liquid coolers as well as coolers constructed on the principle of the phase change heat transfer in closed space; i.e., … [Read more...]
An Introduction to Pulsating Heat Pipes
Modern electronics thermal management faces considerable challenges in the wake of component miniaturization, which has led to higher demands on net heat flux dissipation. With the industry closely following Moore's Law, the future demands are becoming increasingly more challenging [1]. Two-phase passive devices are proven present day solutions. Conventional heat pipe … [Read more...]
