New description: [New technical field] This creation is related to a kind of heat pipe, especially a composite heat pipe structure. [Prior Art] The heat dissipation efficiency of the heat pipe is much larger than the traditional heat dissipation method, such as fan or heat dissipation, and the like. However, today's electronic products are getting faster and faster, and the heat generated is higher and higher, and the heat pipe does not need driving force. It does not occupy space, has no noise, and has high heat dissipation rate. It has become an excellent choice in the industry. The application of heat pipe is also becoming more and more extensive. At present, when the heat pipe is in use, the heat receiving end of the heat pipe is attached to the surface of the electronic component or the heat conducting block, and the working fluid inside the heated end absorbs heat, vaporizes the working fluid, and gradually increases the vapor pressure of the heated end to make the evaporated water The steam will flow to the low pressure cooling end to form a steam flow. After the heat is released from the cooling end, the steam recondenses into a liquid form and is rapidly returned to the heated end by the capillary structure, and the working fluid can be circulated under the flow. • Quickly remove thermal energy from electronic components quickly. + However, the flow of the working fluid inside the heat pipe can be circulated by the design of the capillary structure inside the heat pipe, and the capillary structure currently used can be classified into a groove type, a mesh type or a metal powder sintering. The working fluid inside the heated end of the heat pipe releases heat by the endothermic evaporated water vapor to the cooling end, and recondenses to form a liquid, which is then quickly returned to the heated end by the grooved capillary structure. Although the grooved capillary structure allows the liquid to be quickly returned to the heated end by the cold port p, the grooved capillary structure has a poor water retention (condensation) effect on the heated end, and the area or area where the heated end absorbs heat is reduced. . In addition to M330458, the mesh structure or the capillary structure formed by the metal powder has a good water retention effect. 'There is a large heat absorption area or area, which allows the heat to be collected and receives more heat energy, but is evaporated. After the water vapor flows to the cooling end to release heat and recondense the liquid, the fine structure formed by the mesh or metal powder causes the recondensed liquid to flow back to the heated end at a slower speed, which is a heat dissipation efficiency. ~ [New content] The main purpose of this creation is to propose a hybrid heat pipe structure, a composite heat pipe structure using two different types of capillary structure, and (4) the heated end of the hot officer has a good water retention effect, and The liquid recondensed at the cooling end can also be quickly returned to the heated end. For the purpose of the above, the heat capillary structure of the double capillary structure of the present invention comprises: a tube body and a second capillary structure; wherein the tube body is a circle = a hollow column body, and a body is provided on the inner wall of the tube body a first capillary structure, wherein the first plurality of strips are disposed on the inner wall of the tube body, and a groove is formed between each strip body, and the length of the first capillary tissue is not more than the tube Body length - half. Further, a wall surface on the side of the first capillary structure of the tubular body forms a smooth surface. The second capillary structure is formed by disposing a metal powder on the surface of the β-plane of the mouth of the mouth to form a corresponding structure corresponding to the first capillary structure. The second capillary structure is set to a length not greater than half the length of the tubular body.

Further, a wall surface on the side of the first capillary structure 11 of the tube body i forms a smooth surface 12. 4, the first capillary structure 2 is provided on the surface of the smooth surface 12 by the metal powder particles 21, and after being heated and sintered, the metal powder is consolidated on the surface of the smooth surface 12 to form a first capillary structure.丨 Corresponding configuration. In the present figure, the length of the second capillary structure 3 is set to be no more than half the length of the tubular body 1, as shown in the third figure. When the first and second capillary structures 2 and 2 inside the tubular body 1 are completed, the working fluid is injected into the tubular body, and then the ends of the tubular body are sealed to prevent leakage of the working fluid.
