[Prior Art] Referring to FIG. 1, the "heat sink and its heat sink" disclosed in the Patent No. M423992 of the Republic of China, the heat sink i includes a heat sink U, a plurality of spacers are disposed on the heat sink u and The heat dissipating member 丨丨_; the body-formed political sheet 12, and an upper cover and a lower cover 14 disposed on both sides of the heat dissipating member, the heat dissipating member π includes an inner ring wall lu, an outer ring wall 112, and a plurality of a partition 113 connected between the inner and outer annular walls 1 and 112, and a plurality of flow passages 114 defined by the inner and outer annular walls 111 and 112 and the partition 113 for circulating refrigerant, the upper and lower portions The covers 13, 14 are for sealing both ends of the flow path ιι. Referring to FIG. 2, the upper and lower covers 13, 14 respectively have upper and lower ring passages 131, 141 communicating with the flow passage 114. When the heat sink i is attached to a heat generating component 1 in the manner shown in FIG. When the crucible, the refrigerant located in the flow path 114 and the lower ring passage 141 absorbs heat and changes from a liquid state to a gaseous state, and moves upward in the flow path 114 to dissipate heat through the heat sink 12, and the refrigerant It will cool and change from a gaseous state to a liquid state and flow back into the lower ring passage 141 to repeat the heat dissipation work. Since the heat dissipating member 11 and the heat sink 12 are integrally formed, they are generally manufactured by extrusion or casting. However, when manufactured by the aluminum extrusion method, the density of the heat sink 12 and the partition U3 is denser, and the tonnage required for the machine is increased to generate sufficient thrust, and the larger the tonnage, the M437041 machine. The more expensive the price is, the higher the cost, and the denser the heat sink η and the spacer 113, the greater the frictional resistance and the greater the wear on the machine. The denser the heat sink 12 and the separator 113 are, the more likely the flow of the material in the mold is uneven or the mold is not easily released, resulting in defective products. Thus, the above-described manufacturing method limits the number of the fins 12 and the spacers 113. [New content] Therefore, the object of the present invention is to provide a heat sink that can save manufacturing costs and improve heat dissipation efficiency. The novel heat sink of the present invention comprises a casing, a heat dissipating unit disposed on the surface of the casing, and a conducting unit in the casing. The shovel further includes a hollow outer peripheral wall and a first cover body detachably coupled to the outer peripheral wall, the outer peripheral wall having an inner wall surface, an outer wall surface and a periphery defined by the inner wall surface The accommodating portion has a first opening, and the first cover body blocks the first opening. The heat dissipation sheet 7L includes a plurality of fins spaced apart from the outer wall surface of the outer peripheral wall and extending from the outer wall surface away from the outer peripheral wall. The guiding unit is not integrally formed in the receiving portion and directly contacts the inner wall surface of the outer peripheral wall of the outer casing. The utility model has the advantages that the conductive unit is separated from the outer casing 4 instead of being integrally formed, thereby effectively reducing the frictional resistance during the manufacturing process or the uneven material flow, saving the manufacturing cost and more appropriately increasing the heat dissipation. The number of sheets' further increases the efficiency of heat dissipation. [Embodiment] 4 M437041 The foregoing and other technical contents of the present invention will be clearly described in the following detailed description of the preferred embodiments of the present invention. Before the present invention is described in detail, it is to be noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 3 and FIG. 4 , a first preferred embodiment of the heat dissipation device 2 includes a housing 3 , a heat dissipation unit 4 disposed on a surface of the housing 3 , and a conductive unit 5 disposed in the housing 3 . . The outer casing 3 includes a hollow outer peripheral wall 31 and a first cover 32 detachably coupled to the outer peripheral wall 31. The outer peripheral wall 3 has an inner wall surface 311 and an outer wall surface 312, and The accommodating portion 313 is formed in a blind hole shape and has a first opening 314. The first cover 32 blocks the first opening 314. The heat dissipating unit 4 includes a plurality of fins 41 spaced apart from the outer wall surface 312 of the outer peripheral wall 31 and extending from the outer wall surface 312 away from the outer peripheral wall 31. The conductive unit 5 is disposed in the accommodating portion 313 in a non-integral manner. In the present embodiment, the conductive unit 5 includes an inner peripheral wall 51 having a hollow shape corresponding to the outer peripheral wall 31 of the outer casing 3, and a plurality of pieces. The heat conducting sheet 52 is arranged at intervals and surrounded by the inner peripheral wall 51, and a plurality of flow paths $3 defined by the inner peripheral wall 51 and the heat conducting sheet 52 for the refrigerant to flow, and the inner peripheral wall 51 has an inner portion The heat conducting piece 52 is connected to the inner ring surface 511. The inner peripheral wall 51 is welded to the inner wall surface 311 of the outer peripheral wall 31. The heat conducting sheet 52 is formed by the first opening 314. Extending in a direction away from the first opening 314. The first cover 32 has a first engaging portion 321 which is integrally extended toward the conductive unit 5 and correspondingly engaged in any of the flow passages 53. Of course, the number of the first engaging portions 321 may also be two. In the above, the first cover 32 is more firmly coupled to the conduction unit 5. The first locking portion 321 is designed to be one of the first cover bodies 32 and the outer peripheral wall 31. Other combinations may be used, and are not limited to those disclosed in the embodiment. As shown in FIGS. 4 and 5, the outer wall surface 312 of the outer peripheral wall 31 has a contact portion 315'. The heat sink 41 is disposed in a region other than the contact portion 315. When a heat generating member 9 is in contact with the touch When the portion 315 performs the heat dissipating action, the refrigerant located in the flow path 53 absorbs the heat energy conducted by the heat generating element 9, and the refrigerant absorbs heat and then changes from a liquid state to a gaseous state to rise and move in the flow path 53, and the gaseous refrigerant is allowed to pass. The heat energy is transmitted to the heat dissipating fins 41 through the inner peripheral wall 51 and the outer peripheral wall 31, and is dissipated to achieve a heat dissipating effect. After the heat dissipating heat, the gas is converted into a liquid cancer, and flows downward in the flow channel 53. The endothermic effect is repeated. It should be particularly noted that, as shown in FIGS. 5 and 6, the size of the contact portion 315 can be designed according to a continuous requirement. When the volume of the heat generating member 9 is large, as shown in FIG. The area of the contact portion 315 is made larger, and when the volume of the heat generating element 9 is small, the area of the contact portion 3 1 $ is made smaller as shown in FIG. 6 , and the heat dissipation can be appropriately increased. The number of sheets 41. In addition, as shown in FIG. 7, the inner ring surface 511 of the heat conducting sheet 52 and the inner peripheral wall 51 may be in a zigzag shape, thereby increasing the contact area between the refrigerant and the inner ring surface 5, the heat conducting sheet 52, and further Improve heat dissipation efficiency. Furthermore, as shown in FIG. 8 , the receiving portion 313 of the outer peripheral wall 31 can also be designed to be through-shaped and the receiving portion 313 further has a second opening 316 opposite to the first opening 3M. The piece 52 extends from the first opening 314 to the second opening 316. The outer casing 3 further includes a second cover 33 detachably coupled to the outer (four) 31 (four) to block the second opening 316. The cover body 33 also has a second locking portion 331 extending integrally toward the conductive unit 5 and correspondingly engaged in the any-flow channel 53. The sS: meter provides another use of the heat sink 2 Aspect. In this embodiment, the conductive unit 5 is separately manufactured from the outer casing 3 instead of being formed, which can effectively reduce the aluminum extrusion method and overcome the frictional resistance between the heat sink 41 and the heat conductive sheet 52. The problem of the manufacturing of the heat sink 41 and the heat conductive sheet 52 can be increased by the problem that the heat dissipation fins 41 and the heat conductive sheets 52 are arranged too densely to cause uneven material flow. The quantity 'further increases the heat dissipation efficiency. Referring to Figures 9 and 10, a second preferred embodiment of the heat sink 2 of the present invention is different from the first preferred embodiment in that the heat conducting sheets 52 of the conducting unit 5 are spaced apart therefrom. The inner peripheral wall 51 and the outer peripheral wall 31 of the outer casing 3 are connected to the peripheral wall 51. The flow passage 53 is defined by the inner peripheral wall 51, the outer peripheral wall 31, and the heat conducting sheet 52. In the present embodiment, the conductive unit 5 is placed in the accommodating portion 313 of the outer peripheral wall 31, and the heat conducting sheet 52 is joined to the inner wall surface 311 of the outer peripheral wall 31 by welding. In this embodiment, the first locking portion 31 of the first cover 32 and the second locking portion 31 of the second cover 33 are all engaged on the inner peripheral wall 51. By this design, the present embodiment provides a form different from the first preferred embodiment of the M437041, and the overall shape can be changed depending on the actual use requirements. In addition, in the embodiment, the heat sink 41 and the heat conductive sheet 52 can be formed in a curved shape to increase the contact area between the refrigerant and the heat conductive sheet 52, and the heat sink 41 and the outside. The contact area of the air further improves the heat dissipation efficiency. Referring to FIG. 12', a third preferred embodiment of the heat sink device 2 of the present invention is different from the second preferred embodiment of the present invention. The conductive unit $ further includes a surrounding conductive layer. a connecting piece 54 of 52, wherein the flow path is defined by the inner peripheral wall 51, the connecting piece 54, and the heat conducting piece 52, and the connecting piece 54 is welded to the outer peripheral wall 3 Inner wall surface 311. Through the arrangement of the connecting piece 54, the contact area of the conducting unit 5 with the inner wall surface 311 of the outer peripheral wall 31 can be increased, so that the coupling of the conducting unit 5 and the outer peripheral wall 31 is more stable. As described above, the heat dissipating device 2 of the present invention is manufactured separately from the outer casing 3 by the conducting unit 5, and is not integrally formed, thereby effectively reducing the problem of large frictional resistance or uneven material flow during manufacturing, saving manufacturing. The cost 'more can increase the amount of heat dissipation 41 41 and the number of the heat conductive sheets 52, and further improve the heat dissipation efficiency, so the purpose of the present invention can be achieved. The above-mentioned ones are only the preferred embodiments of the present invention, and are not limited to the scope of the present invention, that is, the simple equivalent changes made by the general patent application scope and the new description contents. And modifications are still within the scope of this new patent.
