Introduction Cooling an electronics system involves transferring heat from various heat sources to the outside ambient. Thermal simulation software provides practitioners with predictions of the temperature and heat flux distributions in and around the system, making it easy to assess the impact of design changes. While the raw simulation results enable us to measure and … [Read more...]
integrating vapor chambers into thermal solutions
Introduction Often in high power density or low profile heat sink applications, the spreading resistances in the base of the heat sink limits the performance of the design. Once it is determined that normal heat sink materials, aluminum or copper, are either insufficient or too bulky to meet the design objectives, the obvious next step is to look at two phase … [Read more...]
Lowering a Notebook CPU Temperature Using a Dual-Tunnel Blower
Figure 1. Side by side comparison of blower technologies. Introduction Notebook computers on the market today may be classified in three categories. In the first category are the super slim and powerful notebooks such as the ThinkPad X300. In the second are the slim and light netbooks such as the ASUS Eee PC, and in the third are the high-end mobile workstations for … [Read more...]

Advanced Aerodynamics for Electronics Cooling Fans
Introduction The performance of electronics cooling fans has been steadily increasing as flow requirements chase higher thermal loading. These advances have been primarily achieved through mechanical and architecture changes. However, the aerodynamic sophistication of these fans has progressed to a lesser degree, and is far removed from turbomachines used in higher power … [Read more...]
