Description of the Invention: [Technical Field] The present invention relates to a heat dissipating device, particularly a heat dissipating device. [Prior Art] When electronic components such as the CPU (CPU) generate a large amount of heat energy, what is the more? The continuous improvement of work ability and volume ", early fever 1 more and more A 'for this industry have adopted the track = the elements of the political heat device 'heat pipe heat transfer speed, long distance, through the implementation: the radiator The heat conduction connection of each part can spread the heat of the electronic component to the various parts of the heat sink and dissipate the heat quickly, so that the heat dissipation performance of the heat sink is effectively improved. Usually, the 'heat pipe is made of a sealed casing (circular tubular or polygonal tubular 1) with a fine structure and a suitable amount of work inside the casing." When the heat is combined with the radiator, it is usually on the radiator. Corresponding to the heat pipe, the structure such as the groove or the perforation is provided for the heat pipe to be accommodated and firmly connected by means of material connection or riveting. The heat pipe f is folded into a U-shape, an L-shape or a V-shape in order to transfer heat to a plurality of locations at the distal end of the heat sink by heat f to be combined with the heat sink. However, when the heat pipe f is folded, the heat transfer capacity of the heat pipe is reduced to a certain extent, and the thermal resistance between the heat sink and the heat sink is combined due to the interface, and the heat is dissipated. The overall heat dissipation performance of the device. [Summary of the Invention] 1312655 ^ It is necessary to provide a heat dissipation device with better heat dissipation efficiency. The guide device includes a heat-conducting base integrally formed, and at least two heat-conducting wings extending from the base. And the plurality of heat dissipating fins extending in the heat conducting wing portion, wherein the heat conducting base and the heat guiding portion are provided with a communicating channel, the channel is sealed with an appropriate amount of working liquid ', and the channel has two open ends' The open end is provided with a tightly fitting sealing member. Purely according to the prior art, the channel is formed by the dispersive (four) body and is not joined to each other to generate an interface thermal resistance, which overcomes the traditional heat pipe bending and the splicing of the plaque. Unfavorable effects such as thermal resistance of the interface, heat can be transferred to the periphery of the heat sink more quickly, and therefore have higher heat dissipation performance. [Embodiment] Referring to the drawings below, The heat dissipating device of the first embodiment of the present invention includes a heat sink 10' of the indented type, and the heat sink 1 includes a rectangular heat conducting base U, and the bottom surface of the heat conducting base 11 Forming a plane (not shown) for the electronic component to be attached, the middle portion of the top surface of the heat-conducting base 11 extends vertically upward at a certain interval with two heat-conducting wings 12. The heat-conducting wing portion 12 has a certain thickness and is plate-shaped, and the two side faces thereof A plurality of parallel spaced fins 13 extend vertically. Each of the heat conducting fins is provided with a channel L having a substantially L-shaped cross section together with the thermally conductive base 11 connected thereto, that is, the channel 14 includes a heat conducting wing portion 12 The vertical section 142, a horizontal section 144 on the base 11, the horizontal sections 144 of the two channels 14 extend toward each other, and each of the channels 14 has an open open end 146 on both sides. 1312655 . After that, the capillary wall 14 is provided with a capillary structure on the inner wall surface of the channel 14 (in fact, the heat-dissipating channel of the present invention can achieve heat transfer and heat dissipation without a capillary structure, but a capillary structure pair is provided to dissipate heat. The heat dissipation performance of the device has a positive effect. The capillary structure 15 of the heat dissipation device of the present invention can be directly formed into a grooved capillary structure with the heat sink 1 或 or formed by various methods currently used in the industry. In the example, the capillary structure of the heat sink 1 such as a honeycomb type capillary structure or a mesh type capillary structure is exemplified, and since the structure of the capillary structure is not the focus of the present invention, the structure is not disclosed in detail in the present specification. Each open end 146 of the channel 14 is provided with a gasket "and seal 17" seal 16 sealing the open end 146, while the seal 17 is tightly fitted between the inner walls of the seal (four) disk channel 14. The shape of the sealing jaw (four) in the longitudinal direction corresponds to the cross-sectional shape of the channel 14, i.e., has an L-shape, and has a relatively wide f portion 162 and a narrower top portion 164 such that the cross section thereof is tapered. The wider base M62 faces the open end 146 and has an area greater than the size of the open end 146 so that the open end 146' can be sealed and the open end 146 of the channel 14 is provided with a bottom 162 of the mountain seal 16 The area is equivalent to the groove (4), the groove (10) = twist and (four) seal (four) thickness phase #. The length/large of the length of the seal ring 17 is also L-shaped. The thickness of the ring arm 172 is gradually thinner toward one end and the inner surface thereof is the tapered surface of the gasket 16, so that the thin edge is inserted into the groove. Between the inner wall surfaces of the channel 14, the open end 146 of the channel 14 is sealed tightly. The top of each of the heat conducting wings 12 and the corresponding capillary structure 15 are: the injection holes 122 and 152 communicating with the channel 14, the injection hole 122, the upper mouth 18 is slid, and the groove is passed through the injection nozzle 18. The channel (4) is filled with a suitable amount of working liquid (not shown) from (gas) 1312655 to a certain degree of vacuum, and then the 'injecting nozzle 18' is sealed. Finally, the interior of the heat sink 1 is formed into two separate cavities having a 1-shaped cross section. The cavity has the same superconducting thermal conductivity as the heat pipe. Please refer to FIG. 4, which is a cross-sectional view showing a second embodiment of the heat sink of the present invention. The main difference between the heat dissipating device of the first embodiment and the first embodiment is that the two L-shaped channels of the first embodiment are changed into a U-shaped channel 14a, that is, the level of the channel 14a in the thermally conductive base 11a. The segment 144a is in communication; in order to smoothly flow the return working liquid of the upper inner wall surface at the bottom of the channel 14a to the lower inner wall surface and to strengthen the strength of the channel 14a, a connection block 19' is provided between the upper and lower inner wall faces. The block 19 may be made of a capillary structure I5a (this embodiment is taken as an example with the capillary structure 15a), or may be separately provided as long as it does not affect the smooth circulation of the working medium in the horizontal section 144a, and the connection is The number of blocks 19 can be appropriately increased as needed. Further, since the channels 14 & are integrally connected, only one injection hole and the injection nozzle are provided. Referring to Figure 5, there is shown a cross-sectional view of a third embodiment of the heat sink of the present invention. The main difference between the second embodiment and the second embodiment is that the heat sink includes three heat conducting wings 12b, and the corresponding channel 14b has a shape of "mountain,". It is understood that the above embodiments The shape of the sealing jaw, the sealing ring and the groove at the open end of the channel changes as the cross-sectional shape of the channel changes. A complete sealing member is formed. ^ As can be seen from the above embodiments, the heat dissipating device of the present invention The inside of the radiator is integrally formed into a channel by aluminum extrusion, and a capillary structure is arranged therein and a male seal is obtained, and finally the same superheat-conducting cavity as the heat pipe is obtained, and aluminum extrusion molding not only reduces the manufacturing cost of the heat sink, but also reduces the manufacturing cost of the heat sink. The interface between the heat sink and the heat sink is greatly reduced: the thermal resistance of the interface is generated by the bonding between the soldering plates (welding, etc.), and it is not necessary to combine the heat and the heat with the heat sink to damage the heat pipe. This action enhances the heat dissipation efficiency of the heat sink I. As described above, the present invention complies with the requirements of the invention patents, and is specifically proposed according to law. However, the above is only a preferred embodiment of the present invention. The equivalent modifications or variations made by God in accordance with the present invention should be covered by the following patents.
