Abstract
A flat heat pipe having a swirl core includes a flat sealed casing having smooth inner walls, a working fluid filled within the flat sealed casing, and a swirl core disposed along a central axis of the flat sealed casing to support upper and lower inner walls of the flat sealed casing. Two airflow channels are formed between the swirl core and left and right inner walls of the flat sealed casing for allowing vapors of the working fluid to flow through. The swirl core is made by winding a metallic woven mesh in at least two circles for allowing the working fluid to flow through. A center of the swirl core is formed with a reflow channel. By this arrangement, the swirl core is used as a wick structure for allowing the working fluid to flow through, thereby saving the cost and time for manufacturing the wick structure.
