New Description: [New Technology Field] [0001] The present invention relates to a heat sink, and more particularly to a thin flat heat pipe. [Prior Art] [0002] Various industrial equipment, measuring instruments, and computer equipment all have integrated circuit components. With the rapid development of the electronics industry, the operating speed of integrated circuit components is becoming faster and faster. The heat is also increased, and the integrated circuit components operate below the maximum operating temperature to ensure normal operation. The heat sink must be used to dissipate heat to the outside world. The traditional heat sink is a metal plate with heat sink fins, but for performance. As with the integrated circuit components with increased heat, the conventional heat sink has been insufficient. Therefore, a heat sink using a heat pipe has been developed. The conventional heat pipe has a cylindrical shape, and the capillary structure and the working fluid are filled in the metal pipe body. It is made after being pumped to a vacuum state to absorb and dissipate heat by the phase change of the working fluid. [0003] However, in the modernization of devices that strive to be lightweight and miniaturized, many devices are becoming smaller and smaller, making conventional cylindrical heat pipes difficult to accommodate in a thin and thin space, and heat pipes for heat connection. Source and heat-dissipating components, but the heat source and heat-dissipating components are separated by a space and there are other components between them. These components block the path from the heat source to the heat-dissipating component. The elbow of space is greatly limited. [0004] In view of this, the present creator has focused on the above-mentioned prior art, and has devoted himself to researching and coordinating the use of academics, trying to improve and enhance the performance, and finally can propose a form number A0101 page 3/18 pages of M375205 kinds of reasonable design And effective this creation. [New Content] [0005] The purpose of the present invention is to provide a thin flat heat pipe that can be accommodated in a thin space without occupying a three-dimensional space, and can avoid other components in the installed space to make space utilization. The rate is more complete. [0006] In order to achieve the above object, the present invention provides a flat heat pipe, comprising: [0007] a metal pipe body; [0008] two flat expansion structures, respectively formed in the first and last two sections of the metal pipe; [0009] An intermediate structure formed by shrinking is formed in a middle portion of the metal pipe body and respectively connected to the two flat expansion structures; [0010] a capillary structure disposed inside the metal pipe body; [0011 a working fluid filled in the interior of the metal pipe and attached to the capillary structure; and [0012] a support member penetrating inside the metal pipe body, the support member pushing against the capillary structure and The inner wall of the metal pipe body is attached. [0013] The effect of the present invention is that the two expansion structures can be closely attached to the heat source and closely adhere to the external heat dissipating component, thereby achieving good heat conduction and heat dissipation effects, and the second expansion structure can be accommodated in the thin space. It does not occupy the three-dimensional space. In addition, the intermediate structure can avoid other components in the installed space, making the overall space utilization more complete. Form No. A0101 Page 4 of 18 M375205 [Embodiment] [0014] The detailed description and technical contents of the present invention are as follows with reference to the drawings, but the drawings are provided for reference and explanation only, and are not intended to be used for this purpose. Creation is limited. [0015] The present invention relates to a flat heat pipe, as shown in the first to sixth figures, the original material map of the original creation, the molding diagram of the first figure after the shrinkage mode, and the bending of the second figure. a folded and flattened molding diagram, a filled capillary structure diagram of the third diagram, a cross-sectional view of the through-supporting member of the fourth figure, and a sealing opening diagram of the fifth figure, the flat-shaped heat pipe comprising a metal pipe body 10, two The expanded structure 11, 12 an intermediate structure 13, a capillary structure 20, a working fluid 30, and a support member 4A. [_], as shown in the figure, the metal tube body ι〇 in the shape of a circular tube is used as the original material of the heat pipe. The metal tube body 1 is made of a material having good thermal conductivity, for example, copper. The material is limited to copper. The metal pipe body 10 is made of copper because the copper is a kind of soft, ductile and lustrous metal. One gram of copper can be drawn into a three-kilometer long filament, or pressed into More than ten T square meters of almost transparent copper pigs, copper's conductivity and thermal conductivity is second only to silver, the axis is cheaper than silver, the inside of the metal body 10 of the wire material is hollow and its two ends In an open state, the metal tube body wall needs to be slightly thinner for subsequent processing, but still has sufficient structural strength. _Please refer to the second and third figures, the two expanded structures "12 are flat and respectively formed on the first and last two sections of the metal pipe body 10, and the intermediate structure 13 is formed on the metal pipe body 10 The middle section and the two expansion structures 11 and 12 respectively are connected to form No. A0101, page 5/18, and the method and program for molding thereof are further explained. The intermediate structure 13 is made of the gold material to be used as the original material. The section (four) tube method is formed by lengthening the diameter of the tube, and the tube shrinking method is a kind of spinning extension processing method. The radial section of the intermediate structure U is still circular, and the second expansion is: The structures 11 and 12 are rotated to the same diameter and the radial surface is still round, and the diameter of the distal intermediate structure 13 is reduced but the interior thereof is still hollow, and the two expanded structures u and 12 are respectively associated with the intermediate structure 13 The joint is formed with a - tapered portion. The two tapered portions (1) and 121 have a conical shape, and the pitch diameter thereof is gradually tapered from the two expanded structures u and 12 toward the intermediate joint (four). [0019] Then, according to the actual needs of the use environment, the intermediate structure (four) is folded or not folded, in the actual state, the bending state, the intermediate knot (four) is formed at the fold - the bending portion m, and then The metal s body 1G having a circular cross section is formed into a flat shape by a pressing operation, that is, the expanded joints (4), 12, the tapered portions (1), m, the intermediate structure, and the bent portion 131 are formed into The flat shape, the flat shape allows the overall thickness to be smaller', and can be accommodated in a thin space, which is the utility of flattening. Referring to the fourth, fifth and sixth figures, the capillary group is disposed from the metal pipe body_opening to the (4) of the gold word (4) and attached to the inner wall of the metal s body 1G, and the metal pipe body 10 is The space of the gas passage is still retained inside, and the capillary structure 2Q is a porous structure which is a sintered structure of a sintered powder, and a method of arranging the capillary structure 20 is conventional, and is not in this embodiment. Make more narratives. [_ After setting up the capillary structure 2, the social flow is filled by the opening (4) of the metal pipe body 1G. The characteristics of the working flow are high vaporization heat, good fluidity, stable chemical properties, and boiling point. Lower, such as water, ethanol form number Α 0101 page 6 / total 18 stomach M375205, acetone, etc., but not limited to these liquids, and the capillary structure 20 absorbs the working fluid 30 through capillary phenomenon, the capillary structure 20 The structure is filled with pores such that the working fluid 30 can be absorbed, and the volume of the injected working fluid 30 corresponds to the total volume of the pores of the capillary structure 20. [0022] Since the metal pipe body 10 has a flat shape as a whole, the support member 40 is bored inside the metal pipe body 10 to prevent the metal pipe body 10 from collapsing, and the support member 40 is pushed against the capillary structure 20 and The method of attaching the support member 40 to the inner wall of the metal pipe body 10 is known, and will not be described in this embodiment. [0023] Next, the inside of the metal pipe body 10 must be evacuated and sealed at both ends of the opening, because if there is an impurity gas (such as air) other than the working fluid in the metal pipe body 10, since the impurity gases do not participate in the phase The change cycle is called a non-condensing gas, and the non-condensing gas, in addition to causing an increase in the starting temperature, is compressed by the gas phase actuating fluid to the condensation section when the phase change cycle of the working fluid 30 is actuated, and occupies a certain amount. Space, which seriously affects its thermal conductivity. [0024] Please refer to the seventh and eighth figures, respectively, for the schematic diagram of the heat generation and the seventh diagram for absorbing the heat of the heat source, in use, one of the two expansion structures 11, 12 As the evaporation section, a heat generating component 40 is attached, because the flat shape can more closely attach the heat generating component 40, and the other serves as a condensation section for a heat sink fin group 50 to be attached, and has a flat shape. The heat dissipating fin set 50 can be attached more closely, and the intermediate structure 13 acts as a heat insulating section, and the thin and curved diameter of the tube can shuttle to evade other components and can achieve the functions of gas and liquid. Form No. 1010101 Page 7 of 18 M375205 [0025] Further explaining the operation of the present creation, the working fluid 30 attached to the capillary structure 20 at the evaporation section is generated by the heating element 40. The heat is heated and evaporated by heat into a gas. The vapor flows through the intermediate structure 13 to the condensation section. The vapor passes through the heat dissipation fin set 50 to dissipate heat to the outside and condenses into a liquid, and the condensed liquid enters the capillary structure at the condensation section. The pores of 20 are replenished to the evaporation section by reflux, thus forming a phase-changing circulation loop to achieve a heat dissipation effect. The improvement of the present invention is that the two expanded structures 11 and 12 of the flat shape can closely adhere to the heat generating component 40 and the heat radiating fin set 50 can be closely adhered to achieve good heat conduction and heat dissipation. The two expanded structures 11, 12 of the functional and flat shape can be accommodated in a thin space, for example, in a notebook computer that is thin and light, and the intermediate structure 13 having the bent portion 131 is Slim and curved, it can avoid other components in the installed space, making the overall space utilization more complete. [0027] Of course, there are many other embodiments of this creation, without departing from the spirit of this creation and its essence. Those skilled in the art can devise various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should belong to the scope of protection of the patent application attached to the present invention.
