Abstract
A heat transmitting device is provided, including a main body and an integrating portion. The main body has at least one opening. The integrating portion is used to seal the opening, and has a first surface and a second surface opposite the first surface. A first welding pattern is formed on the first surface, a second welding pattern is formed on the second surface, and the position of the first welding pattern corresponds to that of the second welding pattern. The type of the first welding pattern and the type of the second welding pattern are asymmetric.
