Abstract
The present invention provides a flat-type heat pipe and a wick structure thereof. The flat-type heat pipe has a flat tube. The wick structure is arranged inside the flat tube along an axial line of the flat tube. The wick structure comprises a first wick portion and two second wick portions connected on both sides of the first wick portion. The thickness of the first wick portion is larger than that of the second wick portion. The first wick portion abuts against an upper inner wall of the flat tube. An air channel is formed between each of the second wick portions and the upper inner wall of the flat tube. The wick structure supports the inner wall of the flat-type heat pipe without providing additional supporting structure, so that the heat pipe can be made more compact.
