Environment-Friendly Vertical Air-Cooling Heatsink: Heatpipe-Based Heatsink "POWER KICKER ® "

A variety of heatsinks of high efficiency has been used in electric power devices for power conversion to maintain their performance. Recently, these heat- sinks are required to have small footprint and environment-friendliness —such as small ozone depletion and reduced environmental impact— as well as high heat-dissipating performance. Accordingly, the authors have developed and put into practical use, jointly with a certain com- pany, "POWER KICKER ® " —an environment-friendly vertical air-cooling heatsink— for heat dis- sipation of high heat-generating devices to replace conventional heatsinks that use CFCs and CFC substitutes. This paper reports on the performance and practical applications of the new heatsink. ABSTRACT
