New description: [New technical field] [0001] The present invention relates to a heat pipe and a heat sink, and more particularly to a heat pipe having an unequal section and a heat sink including the heat pipe. [Prior Art] [0002] The heat pipe (Heat Pipe) is applied to the heat conduction of the heat source of the electronic product, which can effectively overcome the problem of the electronic heat source with increasing heat, and replaces the heat pipe which is only composed of the heat sink. The structure has obviously become the future development trend. However, under the premise that the electronic products are light, thin, short and small, the space and environment of the electronic heat source are subject to considerable restraint, and how to improve the structure of the heat pipe. This is the subject that the creator has to solve. [0003] A conventional heat pipe mainly includes a first-diameter pipe body, a capillary structure and a working fluid, and has a cavity inside the equal-diameter pipe body; the capillary structure is disposed in the cavity and the inner surface of the pipe body They are attached to each other; the working fluid is filled in the cavity and accumulates in the capillary structure, so that a heat pipe is produced. [0004] However, the tube of the conventional heat pipe is of an equal diameter type, and the internal working fluid cannot be accelerated to carry away the heat when it is evaporated into a gas, so that the heat conduction performance is restricted to a considerable extent. In addition, since the pipe body has an equal-diameter structure, when it is required to bend a specific region of the pipe body, the radius of curvature and the diameter ratio are limited, and a small radius of curvature cannot be obtained, so that heat dissipation by the heat pipe is formed. The volume of the device is not easily miniaturized, and it is to be overcome to improve. [New Content] Form No. A0101 Page 3 of 21 M419385 [0005] One of the purposes of this creation is to provide a heat pipe having unequal sections, which adopts unequal circumferential dimensions for the evaporation section and each condensation section. The setting can increase the flow velocity and thermal conductivity of the internal gas. [0006] In order to achieve the above object, the present invention provides a heat pipe having unequal sections, including an evaporation section and a second condensation section, the evaporation section being located in a portion of the heat pipe; the two condensation sections being respectively formed in the evaporation On both sides of the segment, the two condensation sections communicate with the interior of the evaporation section, and the circumference of the evaporation section is larger than the circumference of each of the condensation sections. [0007] One object of the present invention is to provide a heat dissipating device which can improve the flow velocity and thermal conductivity of a gas inside a heat pipe, and can obtain a heat pipe having a small curvature radius to reduce the overall volume of the heat dissipating device. [0008] In order to achieve the above object, the present invention provides a heat dissipating device comprising a heat pipe and a heat sink group, the heat pipe comprising an evaporation section and a second condensation section, the evaporation section being located in a part of the heat pipe; The condensation sections are respectively formed on both sides of the evaporation section, and the two condensation sections are in communication with the interior of the evaporation section, and the circumference of the evaporation section is larger than the circumference of each of the condensation sections. The heat sink set is sleeved on any of the condensation sections. [0009] The present invention also has the following effects: the respective condensation sections are connected to the heat sink group to achieve the common effect of the heat sink group. It utilizes the composite capillary structure inside each condensation section to accelerate the return flow of the liquid to prevent air burning. Since the evaporation section has a large cross section, the area which can be directly attached to the heat source is large and has a large vapor amount, and the heat dissipation performance can be improved. By the small section of the condensation section, it does not interfere with other adjacent electronic components.

The third picture shows). φ [〇〇13] The middle portion of the pipe body 10 can be expanded to expand, so that the inner diameter of the cavity 11a of the inter-card portion is larger than the inner diameter of the cavity lib of the two sides. Similarly, the tube processing method can be used to shrink the two sides of the tube body 1 so that the inner diameter of the cavity Ub at both sides is smaller than the volume 11 a of the intermediate portion. [OOH] can be laid on the inner surface of each cavity lib by laying a metal powder, a woven mesh or a fiber bundle, etc., thereby forming a second capillary structure 30 of the original heat pipe; at this time, the cavity of the pipe body 10 The first capillary structure 20 and the second capillary structure 30 are simultaneously present in llb.

[0016] - month sees the first, to nine The heat pipe of the other embodiment of the present invention is different from the heat pipe W of the foregoing embodiment in that the pipe body 1 is flat and straight e 'the evaporation section of the heat officer 1' The surrounding flat perimeter is also larger than the flat perimeter of each condensed section 1〇2 (or 1〇3). The inner portion of the hair segment m has a first capillary structure composed of a plurality of grooves 12 and a plurality of ridges 13, and each of the condensation segments (10) and 103 has the aforementioned first capillary structure 2 () and is composed of metal powder, woven mesh or fiber. The second capillary group _ which is composed of bundles _. «The eight and nine figures clearly show that the volume of the cavity 1 la is larger than the volume of the cavity 丨 ib', so that the working fluid 40 is heated by the liquid In the case of gas, the flow of these gases can be accelerated. In addition, due to the heat pipe, the evaporation section 101 and the condensation section 1〇2 (or 1〇3) are flat, so the heat pipe 1 and the heat source or heat dissipation|§ The contact area will be greatly improved, which will further improve the heat dissipation efficiency.

The two ends are horizontally bent and extended for each condensation section 102, 103 The heat sinks 5 are respectively attached to the free ends, and the heat dissipation fan 6 is respectively installed on one side of each of the heat sink groups 5, thereby forming the heat sink of the present invention; due to the outer circumference of each of the condensation sections 1〇2 and 1〇3 The size is smaller than the outer peripheral dimension of the evaporation section 1〇1, so that in addition to the small curvature half during the bending process of each of the condensation sections 102, 103, the overall volume of the heat sink can be greatly reduced. In addition, the contact area between the evaporation section 101 and the heat source is large, so that more heat energy can be absorbed to each of the condensation sections 102, 103, and the heat dissipation efficiency is better. [0018] Please refer to FIG. The heat dissipating device of another embodiment, the main difference between the heat dissipating device and the heat dissipating device is that each condensation section, 103 is first bent from the two ends of the evaporation section ιοί perpendicular to the evaporation section 1〇1, and then Parallel to the direction of the evaporation section 101, the fin group 5 provides the respective condensation sections 1〇2, 1〇3 for the connection; in addition to the common effect of the heat sink group 5, the heat sink group 5 can be Heat pipes are fixed to each other [0019] In addition, The created heat pipe can be circular except that the condensation section 101 can be circular and the condensation sections 102 and 1〇3 are flat; the evaporation section 101 can be flat and each condensation section is 1〇. 2, 1〇3 is circular, the evaporation section 101 can be semicircular (as shown in the twelfth figure) and each condensation section 102, 103 is circular; or the evaporation section 1〇1 can be semicircular The respective condensation sections 102, 103 are flat. _, in summary, the 'heat pipe with unequal cross-sections of this creation can break the expected use purpose, and solve the lack of knowledge, and because of the new meaning and form number Α 010丨 Page 7 of 21 M419385 Progressive, fully in line with the requirements of the new patent application, apply in accordance with the patent law, please check and grant the patent in this case to protect the rights of the creator.
