Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a heat dissipating device, and more particularly to a heat dissipating device with a heat pipe. [Prior Art] [0002] With the continuous advancement of large-scale integrated circuit technology, the electronics industry has developed rapidly and rapidly, and the integration of computer central processing units and chips and other electronic components is getting higher and higher, and the operation speed is getting faster. Therefore, the heat generated along with it increases accordingly. If the heat is not released in time, the internal temperature of the electronic component will rise rapidly, which will affect the stability and speed of its operation. The impact has become increasingly prominent and has become a barrier to the launch of high-speed processors. [0003] As new types of chips and processors continue to be introduced, the heat generation is getting higher and higher, and relying solely on the heat dissipation of the electronic components is far from being able to meet the needs of practical applications. The industry usually installs a heat sink on the surface of the electronic components to assist heat dissipation. With the continuous improvement of the demand for heat dissipation, the technology related to heat sinks has also been rapidly developed. [0_Early, the raw materials are directly used for hot materials, and the conduction efficiency is low. Then the industry introduced a new kind of hearing device, which no longer uses metal conduction heat dissipation, but mainly uses the physical phenomenon that the liquid maintains the temperature in the two-phase change and can absorb or release a large amount of heat to realize the heat transfer. The heat pipe ° is favored by the industry because of its better heat transfer performance. 096115859 The heat sinks in the industry are endless.
