Abstract
An anti-breaking structure of an end closure of a heat pipe is formed at a tapered end of the heat pipe, and a soldering joint is formed at an upper end of the anti-breaking structure. The anti-breaking structure includes an uneven rib coupled longitudinally between the tapered end and the soldering joint, and two wing portions extended outward from the left and right outer sides of the uneven rib, and one surface of the uneven rib is convex and another backside surface of the uneven rib is concave, and both uneven rib and wing portions are formed by pressing the heat pipe to constitute the anti-breaking structure.
