The clamping force is concentrated only on the sides of the earth groove. The clamping force is not very stable, in addition, :Hot:: The position at the time of insertion is not correct, or it is affected by the vibration during the punching. The k-shaped fins are bounced off the groove bottom, so there is not the bottom of the groove of the radiator groove. Not only can not be combined with the heat sink, the high heat loss will occur, and the heat sink will be easy to shake or 201135178. The applicant for this case has been in the Republic of China in 1998 (2〇〇9) 〇April 23 The "heat sink" design (hereinafter referred to as the previous case) of the first leak (four) is proposed, which is provided with a first convex portion and a second convex portion on both sides of the groove of the base, but the base groove of the previous case is only a single-class groove, so the l-shaped single fold at the bottom end of the heat sink is inserted deep Very limited, the contact area between the W single-folded portion and the base groove is also relatively limited. Moreover, the first convex portion of the front case can only produce a downward force pressing combination for the L-shaped single-folded portion of the heat sink. Therefore, there is still room for improvement in terms of stability or contact area of the bond. SUMMARY OF THE INVENTION The main object of the present invention is to provide a heat sink design, which includes a plurality of heat sinks and a base, in particular, the bottom end of each heat sink is formed with a two-section bent 2-shaped bend. In the section, the silk surface is provided with a plurality of adjacent double-stage grooves, and the first convex portion and the second convex portion are respectively disposed on both sides of the groove, so that the double-shaped shape is inserted in the U-shape and the base is inserted. After the groove, the first convex portion and the second convex portion are stamped by the stamping die of the adapted shape, forcing the first convex portion to deform and simultaneously generating the "downward" and the lateral pressing force of the lateral direction 7 It is confirmed that the combination of the hot film and the base is more stable, and the contact area between the heat sink and the base can be increased, and the heat transfer efficiency is improved. The second object of the present invention is to provide a heat sink design, which can be optionally implemented as a rectangle. The seat body or the hollow tubular (or solid cylindrical) seat body is used for matching and matching of the heat sinks to enable the formation of heat sinks of various shapes. A further object of the present invention is to provide a heat sink design, the first convex portion and the second convex portion of the base double-shaped groove of the 201135178, the convexity of the two is approximately equal, and thus for the zigzag shape The bent portion can produce a combination of: placing and pressing. Another purpose of this month is to provide a heat sink design in which a heat pipe that is in a bottom or bottomless manner is tightly coupled between the heat sink and the base to accelerate heat conduction through the heat pipe. [Embodiment] The structure and other functions and purposes of the present invention are described in detail below. As shown in the first and second figures, the "heat sink" of the present invention includes a base 1 and The plurality of fins 2, wherein: the base 1' is provided with a plurality of adjacent double-stage grooves u on the surface, and the grooves (4) on both sides of each of the double-stage grooves 11 are respectively provided with the first protrusions! 2 and the = convex portion 13, and the first convex portion 12 and the second convex portion 13 can be implemented to have an equal convex height; the pulp fins 2 are formed at the bottom end of each of the sheets - a zigzag bend Folding, the end of each fin 2 is provided with a root of a zigzag feature, and the Z sub-reading portion 21 is matched with a double-stage groove 11 9 implanted with the base 丨. The zigzag-shaped folded portion 21 of the fin 2 is utilized. After matching the double-stage grooves 11 of the inserted base i, the stamping die 3 of the adapted shape can be used to respectively press the first convex portion 12 and the first convex portion 13 (such as the third conductive portion) to force the first ΓΓ 2 After the deformation, both the "downward" and "lateral" (four) kinds of pressing joint forces (such as the fourth figure) are generated simultaneously, and the first convex portion 12 and the second convex portion 13 are simultaneously separated by the sheet 2, and the curved shape is bent. The end root of the folded portion 21 also completely penetrates the bottom step 1U of 201135178, thus ensuring the heat sink 2 and the base fifth and sixth figures, and increases the contact area of the heat sink 2 with the base 1 to improve heat transfer efficiency. The figure and the sixth figure show 'the base 1 and the plural number of the present invention', and the piece 2' can be compared with the embodiment of the prior case and the plural number of "two tightly combined" - more than one is attached to the bottom = 4', the heat official 4 can be tightly coupled to the plurality of heat sinks 2, and simultaneously embedded, combined with the base 1' and forming a tangent pressure plane with the bottom surface of the base 1, so that the heat pipe 4 can be exposed to the bottom; The heat pipe can also be implemented as a combination form that is not bottomed or exposed when necessary. According to the design spirit of the present invention, the base i can be implemented as a rectangular base body according to the first figure to the second figure. Alternatively, it can be selected as a hollow official shape (or solid cylindrical shape) for the base body. The matching of the heat sinks is as shown in the embodiment of the seventh to ninth figures. When the base la is in the form of a hollow tubular U-shaped solid cylindrical body, the same reason can be opened on the circumferential surface of the base work a. Singing a plurality of adjacent double-stage grooves, and the groove walls on both sides of each of the double-stage grooves are also respectively provided with a first convex portion 12a and a second convex portion 13a, and the first convex portion 12a and the second convex portion 13a It can be implemented to have approximately equal protrusion heights, whereby the hollow tube-shaped (or solid cylindrical) base ia can also match the Z-shaped bent portion 21 a of the bottom fins of the plurality of fins 23 to the implant base 1 a The double-stage groove, and using the adapted stamping die to press the first convex portion 12a and the second convex portion 13a' to force the first convex portion 12a to deform, and simultaneously produce "downward" and "lateral" two pressing The combined force causes the zigzag bent portion 21a of the end root to also completely penetrate the double-stage groove The step surface, therefore, the radiation direction is formed by a heat sink that is tightly coupled to form another form, so 201135178 is selected to be implemented as a rectangular base or medium to provide various forms of dispersion. The invention can be used according to different needs. Empty tubular (or solid cylindrical) seat, suitable for heaters. 1 Feng invented the heat sink Z-shaped bending part and the insertion of the base, the shape: Shen has been significantly different, and can achieve the expected effect without flaws, in order to apply for the May patent according to law, please grant the patent according to law, the real sense of virtue.
