Heat dissipation unit with mounting structure
A heat dissipation unit with mounting structure includes a main body and a plurality of mounting elements. The main body internally defines a chamber, and includes a plurality of supports located in the chamber, a working fluid filled in the chamber, and at least one wick structure formed on inner wall surfaces of the chamber. The mounting elements are externally connected to one side of the main body at positions corresponding to the supports in the chamber, and respectively define an internally threaded coupling bore therein. With these arrangements, it is able to ensure the air-tightness of the chamber of the heat dissipation unit having the mounting elements provided thereon. Further, the mounting elements with internally threaded coupling bore also provide good locking effect for the heat dissipation unit to securely connect with other elements via the mounting elements.
