Foreword

The Tenth International Heat Pipe Symposium (10IHPS) hosted by Tamkang University was held on 6 th to 9 th November 2011. This Symposium was initiated by the Japan Association for Heat Pipe (JAHP), and the 1 st to 4 th Symposium were held in Japan, those meetings took place in Tokyo(1985), Osaka(1987), Tsukuba(1988, 1994), and then the 5 th to 9 th Symposium were done in Australia(Melbourne, 1996), Thailand(Chiang Mai, 2000), Korea(Jeju-Do, 2003), Japan(Kumamoto, 2006) and Malaysia(Kuala Lumpur, 2008) respectively. More than 100 local and international persons participated in this Symposium. These Participants came from far away countries like Australia, Brazil, China, France, Germany, India, Japan, Korea, Malaysia, Russia, South Africa, Thailand, UK, USA and not forgetting Taiwan.

This Symposium is held once every 2 or 3 years and alternating with the International Heat Pipe Conference (IHPC). It will bring together engineers, scientists and industries working in the field of heat and mass transfer especially in heat pipe science and technology. Heat pipes are highly efficient heat transfer devices and are becoming increasingly applied not only in the fields of electronic cooling but also for heat and energy recovery. This international symposium provided a forum for the exchange of the latest scientific R & D information as well as the technologies developed for commercial enhancement of heat pipes application. I would like to express my sincere gratitude to the five keynote speakers, Amir Faghri, Masataka Mochizuki, Joon Hong Boo, Robert Dobson, and Wei Qu. Moreover, I would like to warmly thank Lung ‐Jieh Yang, Jin ‐Shin Ho and Huei-Nan Huang for preparing the symposium proceedings and continuous help throughout the symposium organization.

This Symposium was sponsored by Ministry of Education, National Science Council, Ministry of Foreign Affairs, Ministry of Economic Affairs Bureau of Foreign Trade, Japan Association for Heat Pipe, Taiwan Thermal Management Association, and Tamkang University. Finally, on behalf of the local organizing committee, I sincerely express my appreciation to the members of the International Advisory Board, the Local Organizing Committee, and the sponsors. Special thanks should be given to the administrative staff and graduate students at Tamkang University, who put an enormous of works into the various activities of the Symposium.
