Field of the Invention The present invention relates to a heat sink having a heat radiating fin which is subjected to bending processing to increase a heat radiating area. [Prior Art] A device caused by heat generated by each component due to the miniaturization and high integration of electronic components such as a CPU such as a CPU of a computer, LEDs, liquid crystals, PDPs, ELs, and light-emitting elements such as mobile phones The reduction in service life and the occurrence of erroneous actions have gradually become a major problem, and the requirements for heat dissipation measures for electronic components have been increasing year by year. As a countermeasure against heat dissipation of electronic components, in addition to forced cooling using a fan or the like, heat-dissipating components composed of metallic heat-dissipating fins are also used. The heat sink fins increase the heat dissipation area to improve heat dissipation. Therefore, a heat sink fin which is bent by a metal plate to increase a heat radiating area has been developed. (Refer to Patent Document 1) The heat radiating fins fix the heat radiating fins to a heat transfer portion thermally coupled to a heat source. The fins are formed by forming a thin metal plate into a valley portion that is in contact with the heat conducting portion, a standing portion that is formed in a standing position from the valley portion, and a mountain portion that is bent to be folded back at the top of the standing portion. The standing portion serves as a structure in which opposite metal thin plates are in close contact with each other. [Patent Document 1] JP-A-2007-27544 [Summary of the Invention] [Problems to be Solved by the Invention] -5-201128743 The above heat-dissipating fins are characterized in that they can be bent to increase the heat-dissipating area, but Because of the use of metal plates, there is a disadvantage of becoming heavy. In particular, when the pitch of the mountain portion is narrowed and the upper and lower widths of the standing portion are increased to increase the heat dissipation area, there is a disadvantage that the weight is increased. Moreover, since a wide-area metal plate is used, there is a disadvantage that the cost becomes high. The heavy fins are required to be strong for fixing, and the cost of the mounting portion is also increased.

Further, although the heat dissipating fins are fixed to the semiconductor elements such as the energy transistors and the energy FETs fixed to the circuit board, the heat dissipating fins are required to be lightweight and excellent in supporting the semiconductor elements by the circuit board. Thermal characteristics. The present invention has been developed in order to solve the above problems. An important object of the present invention is to provide a heat sink that can increase the heat dissipation area of the heat sink fins to achieve excellent heat dissipation characteristics and form an extremely light paper sheet. Further, another important object of the present invention is to provide a heat sink of a paper sheet which can be mass-produced inexpensively. [Means for Solving the Problem and Effect of the Invention] The heat sink of the paper sheet of claim 1 of the present invention is configured such that the heat radiating fins 1, 21, 31 formed by bending are fixed to the heat conducting portions 2, 22, 32 -6 - 201128743, 42. In the heat sink of the paper sheet, the heat radiating fins 1, 21, and 31 are made of a wet paper sheet 3 formed by adding heat conductive powder to the fibers, and the heat radiating fins 1, 21, and 31 are bent into a zigzag shape. In the state of thermal bonding, the heat conducting portions 2, 22, 32, and 42 are fixed. The heat sink of the above paper sheet has the feature of being able to increase the heat dissipation area of the heat radiating fins and achieve excellent heat dissipation characteristics, and is extremely light. This is because the heat sink fins are made of paper which is wet paper. By the way, the LED light source in the form of a light bulb without a heat sink will have a maximum temperature of about 10 ° C, but the relative heat dissipation of the paper sheet of the present invention is fixed in the same LED light source. The temperature can be set to 5 2 ° C ~ 6 3 ° C, which can be reduced by about 40 ° C. Further, since the weight of the heat sink fin as the heat sink of the paper sheet is only 12 g to 90 g, the light source of various forms can be lightened, and the heat generated by the LED can be efficiently dissipated to reduce the temperature rise. Further, not only LEDs but also semiconductor elements have characteristics in which the efficiency is lowered due to an increase in temperature. For example, an LED will decrease in luminous efficiency as temperature rises, and conversely, when the temperature is lowered from 60 ° C to 30 ° C, the luminous efficiency is increased by about 50%. Further, when the efficiency of the semiconductor element is lowered due to an increase in temperature, the power loss is increased and the amount of heat generation is increased. Therefore, although the semiconductor element can be cooled by efficient heat dissipation, when the heat dissipation is insufficient, the temperature rises again, and when the temperature rises, the heat generation further increases, and the temperature becomes higher. A vicious cycle of reducing efficiency arises. Since the heat sink of the paper sheet of the present invention has a light weight and excellent heat dissipation characteristics, the LED light source fixed in the form of a light bulb can be obtained, and the entire weight can be reduced, and the temperature rise can be reduced, and the luminous efficiency can be improved by 201128743. The ideal feature. Further, the heat sink of the above paper sheet is characterized in that it can be mass-produced at low cost, in addition to being lightweight, by converting the heat-dissipating fins from the metal sheet to the paper sheet. The heat sink of the paper sheet of claim 2 of the present invention is preferably such that the curved edges 4 of the paper sheet 3 bent in a sawtooth shape are thermally bonded to the heat conducting portions 2, 22, 32, and 42. The heat sink of the paper sheet of claim 3 of the present invention is a heat-dissipating fin formed by the paper sheet 3 by bending the paper sheet 3 which is bent into a zigzag shape into a planar shape as heat-dissipating fins 1, 21, and 31. It is preferable that the bending edges 4 of the first, the second, and the third portions 21 are fixed to the heat conducting portion 2 in a thermally bonded state. Since the heat sink has a flat fin formed by bending a paper sheet formed into a zigzag paper sheet, it can thermally combine with a planar heat generating component with a wide heat transfer area, and can be efficiently performed. In the heat sink of the paper sheet of claim 4 of the present invention, it is preferable that the curved end surface 5 bent into the zigzag paper sheet 3 is fixed to the heat conduction portion 2 in a thermally bonded state. In the present specification, the curved end surface means a surface including an end edge of a paper sheet which is bent into a zigzag shape, that is, a surface including an end edge of a plurality of curved surfaces which have been bent. In the heat sink of the paper sheet of claim 5, the heat dissipating fin 1 has a paper sheet 3 formed by bending into a zigzag shape as a cylindrical shape, and then the curved end surface 5 of the paper sheet 3 which has been bent and processed is The thermal bonding state is fixed to the heat transfer portion 2 at 201128743. Since the heat sink of the paper sheet is formed into a cylindrical shape by bending into a zigzag paper sheet, it can be efficiently combined with the cylindrical heat generating member to dissipate heat. The heat sink of the paper sheet of claim 6 of the present invention has a plurality of sheets of reinforcing sheets 8 arranged in parallel with each other, and between the opposing reinforcing sheets 8 is arranged to bend the paper sheet 3 into a zigzag shape. The heat dissipation fins 1 are formed, and the heat dissipation fins 1 are fixed to the reinforcing sheets 8 in a thermally bonded state by the curved edges 4 of the zigzag paper sheets 3, and are bent into the curved end faces 5 of the zigzag paper sheets 3. It is preferable to fix it to the heat conduction portion 2 in a thermally bonded state. Since the heat sink is provided with a zigzag paper sheet between a plurality of reinforcing sheets, it has a feature of increasing the heat dissipation area and efficiently dissipating heat. Further, since the zigzag paper sheets are sandwiched between the opposing reinforcing sheets, the heat dissipating fins provided in the reinforcing sheets can be protected. The heat sink of the paper sheet of claim 7 of the present invention preferably has the heat conducting portions 2, 22, 32, 42 as the paper sheets 1 1 and 12, the metal sheets, and the thermally conductive plastic sheet _ sheet 13. In the heat sink, the heat radiating fins fixed by any one of a paper sheet and a metal plate 'thermally conductive plastic sheet' can dissipate the heat of the heat generating portion by the heat radiating fins. In the heat sink of the paper sheet of claim 8, the thickness of the paper sheet 3 of the heat radiation fins 1, 21, 31 is preferably lmrn or less and 0.05 mm or more. The heat sink can achieve sufficient strength to make the heat sink fins -9-201128743, and it can also have light weight and excellent heat dissipation characteristics. The heat sink of the paper sheet of claim 9 of the present invention is characterized in that the fibers of the paper sheets 3 of the heat dissipation fins 1, 21, 31 are beaten, and the beating pulp having an innumerable number of fine fibers on the surface and the non-beating without beating are used. As the fiber, the paper sheet 3 which is subjected to wet papermaking after adding the heat conductive powder to the beaten pulp and the non-slurry fiber is preferably used as the heat radiating fins 1, 21, and 31. The above heat sink of the paper sheet can improve the bending strength of the paper sheet used for the heat sink fins, and can be easily bent and improved in thermal conductivity. It is possible to achieve the desired characteristics as a paper sheet. Further, the characteristics of the strength of the vibration of the paper sheet used for the heat dissipation fins can be achieved. The above paper sheet has a folding strength of up to 4 8 2 9 times, and the thermal conductivity is also 38.15 W/m · K, which can achieve excellent heat dissipation characteristics of the heat sink fins. The heat sink of the above paper sheet, the beaten pulp used for the paper sheets 3 of the heat radiating fins 1, 21, 31, may be mixed with any one of a plurality of beater pulps composed of synthetic fibers and natural pulp. use. As the pulping pulp of the synthetic fiber, any of acrylic fiber, polyarylate fiber, polyamide fiber, polyethylene fiber, polypropylene fiber, PBO (poly(p-phenylenebenzobisoxazole)) fiber, and ruthenium fiber can be used. Further, as the natural pulp, any of wood pulp and non-wood pulp can be used, and 'non-beating fibers can be used, and polyester fiber, polyamide fiber, polypropylene fiber, polyimide fiber, polyethylene fiber can be used.

Also, the average particle size of the thermally conductive powder can be used as a crucible. 1μιη to 5〇〇μηι. Further, the paper sheet 3 of the heat-dissipating fins 1, 2 1 and 3 1 can be bonded to a fiber by adding a synthetic resin as a binder, followed by wet papermaking. As the synthetic resin, a polyacrylate copolymer resin, a polyvinyl acetate resin, a polyvinyl alcohol resin, a NBR (nitrile rubber) resin, an SBR (styrene butadiene rubber) resin, or a polycarbamic acid can be used. Any of the thermoplastic resins of the ester resin or any of the thermosetting resins of any one of a phenol resin and an epoxy resin. Further, the heat-dissipating fins 1, 21, and 3 may be used as a paper sheet 3 which is formed by wet papermaking by a mold paper formed by adding heat-conductive powder to the fiber, and heat dissipation of the paper sheet of claim 2 of the present invention. Preferably, the heat dissipating fins 1 〇 1 are fixed to the heat conducting portion 102. 1. The heat sink fins 1 0 1 are paper sheets of wet papermaking formed by heating the conductive powder to the fibers. 1 03 to form. Paper-11 - 201128743 Sheet 1 〇3 series is bent at 1 0 4 in the bending line, with the bending line 1 〇 4 as the boundary, and is divided into heat-dissipating fins 1 〇 1 and fixed paper sheets 1 0 6 ° heat sink paper sheets The fixed paper sheet portion 106 of 1300 is fixed to the heat conduction portion 102 in a thermally bonded state, and heat of the heat conduction portion 102 is thermally transferred from the fixed paper sheet portion 1〇6 to the heat dissipation fins 101 to dissipate heat. The heat sink of the above paper sheet has the characteristics of not only increasing the heat radiating area of the heat radiating fin but also achieving excellent heat dissipation characteristics and achieving extremely light weight. This is because the heat sink fins are made of paper for wet papermaking. Since the paper sheet subjected to wet papermaking exhibits extremely excellent thermal conductivity in the surface direction, heat generation in the heat conduction portion can be quickly conducted to a wide area, and heat can be efficiently dissipated. Further, the surface has an infinite number of fine concavities and convexities, and the surface area is substantially large, and the heat dissipating area becomes so that heat can be efficiently dissipated from the surface. By the way, the LED light source provided with the aluminum heat sink is continuously placed in a state where the outside air temperature is 20 ° C, so that the temperature of the LED rises to 6 TC until it is stable, and the same is true. The LED light source, by fixing the heat sink of the paper sheet of the present invention, can dissipate the temperature of the LED to a low temperature of 55 ° C to 62 ° C which is not lost to the heavy aluminum heat sink. Since the heat sink fin is extremely light as a heat sink of the paper sheet, it is only about 1 〇〇g, so that the light source of various forms can be lightened, and the heat generated by the LED can be effectively dissipated to reduce the temperature rise. . Further, not only LEDs but also semiconductor elements have characteristics in which the efficiency is lowered due to an increase in temperature. For example, the LED will decrease in luminous efficiency as the temperature rises, and conversely, when the temperature is lowered from 60 ° C to 30 ° C, the luminous efficiency will increase by about 50%. What is more problematic is that when the efficiency of the semiconductor element -12-201128743 is lowered due to an increase in temperature, the power loss is increased and the amount of heat generation is increased. Therefore, although the semiconductor element can be cooled by efficient heat dissipation, when the heat dissipation is insufficient, the temperature rises again, and when the temperature rises, the heat generation further increases, and the temperature becomes higher. A vicious cycle of reducing efficiency arises.
