4. Creation instructions (1) [Technical field to which the new type belongs] The heat sink (2), especially the tightness of the elastic clamp formed on the outside. This creative system provides a heat pipe radiator and an electronic heating element, which can act on the heat pipe to increase the retention of the heat sink and heat pipe. [Previous technology] With the development of information technology and computer industry + ^ ^, wv 'Electronic components such as Φ

The heat generated by the central processing unit chip and the memory is increasingly fatal to the ancient T 4 叼, and the size of the central core is small. In order to effectively dissipate this dense heat to the outside of the system, the wooden 4 elements operate at the permitted temperature, usually with Dream, U maintain ^ 1 父 The thermal pad of the parent's large base area is added to the surface of the heating electronic component 'or to increase the speed of the scattered wind to increase its overall heat dissipation efficiency; so, it will be derived; ^ 喿 音 = J 里Relevant issues such as cost, system complexity, etc. make the aforementioned solutions not a good solution for heat dissipation of electronic components. 'At present, the industry uses the characteristics of high heat transfer capacity, rapid heat transfer, high thermal conductivity, light weight, simple structure, and multi-purpose of the heat pipe for the heat dissipation of electronic heating components.' It can transfer a large amount of heat without consuming electricity, so It is very suitable for the heat dissipation requirements of electronic products; therefore, a heat pipe radiator formed by combining a heat pipe with a heat sink has become an important issue for solving heat dissipation. The conventional heat pipe radiator mainly includes a plurality of radiating fins and heat pipes. Each radiating fin has a plate-shaped body, and a plurality of perforations are provided at the center of the body. A peripheral edge of each perforation is provided with a flange. The flange The shape of the inner edge is larger than the shape of the outer edge of the heat pipe, and the inner wall surface of each flange or the outer surface of the heat pipe is coated with a heat conductive medium. When combined, the heat pipe is connected in series to each heat sink.

4. Creation instructions (2) In the perforation, however, the shape is greater than the heat and the low melting point leads to the manufacturing cost of the heat-conducting medium. However, the heat transfer effect of the coating guide or the heat sink will be added in addition to the conventional tube. The heat medium and the material are penetrated when the heat transfer between the perforated heat pipe and the heat medium is poor. The shape of the heat dissipation edge of the heat pipe of the dish fear tower, so that it is used to form the inner edge of the inner wall of the hole after each fin, the conduction rate, method, and device, so the guide is added before. The scraped shape and heat directly contact the heat medium, so that the phase of the heat medium is coated on the two heat sinks. During assembly, the outer edge of the tube will increase the contact area of the heat conduction fast heat pipe radiator. The perforated gap between the contact of the flange of the heat pipe and the process of hot melting is reduced. The heat dissipation inner wall with a much lower rate is coated with the inner edge to avoid being too large and larger than the efficiency and point of the heat pipe and has been engaged in the industry for many years. After researching and cooperating with my heart, I finally came up with a design. Therefore, the author feels the above problem = experience, and uses it consistently for the problems that can be improved. In the spirit of excellence, rationally and effectively improve the above problems Original creation. [New content] Sanji (Chuang Er " Ti's purpose is to provide-a kind of heat pipe radiator and its can be used overnight), the use of flanged ring body with equally spaced through grooves, tubes ！ 'Secure form an elastic clip outline to increase the heat sink rate and heat bite rate, so as to improve the heat transfer effect and heat dissipation of the heat pipe radiator. In order to achieve the above purpose, this creation is to mention a radiator and its heat dissipation. Piece (b), the heat pipe radiator includes :, number: heat piece and heat
