If it is impossible to dissipate the notebook computer: the heat is dissipated in a timely and effective manner, it will greatly reduce the working performance of the electronic reading, and at the same time reduce the use of the electronic tree, so the electronic components must be dissipated. In the notebook computer, the electronic components (4) are often placed by a heat-conducting plate, a heat pipe, and a heat-dissipating piece. The peak of the 2 electronic components on the electronic components generated by the _, the 敎 tube will be heat-conducting, f-dispersion group for thermal connection and the heat-conducting plate absorbs the U-quantity: gas: blow = Γ away: fan outlet 'The centrifugal fan produces the final heat dissipation: the heat exchange of the heat sink is correct, and the heat dissipation performance of the thermal shock has a great influence. The size of the product is the same and the spacing is equal: the heat sink chip group usually consists of the heat dissipation area outside the group, and the common method, the total distance between the two hot plates of the chip group to increase the heat sink 6 and the number of heat sinks can be obtained. Lifting, but at the same time will make y heat dissipation of the heat sink. Manufacturing equipment with high recording capacity [Summary of the invention] In view of this, it is necessary to provide a kind of low-cost manufacturing cost _ with secret heat dissipation performance - a kind of heat sink, including - used by it heat sink.

The scatter-correcting group further includes a second heat sink of the Wei Wei wing portion. The airflow velocity is set in the near wind region where the airflow velocity is large, and the second scatter is set in the windward side region where the airflow velocity is small at the air outlet. Compared with the prior art, in the above-mentioned heat dissipating device, the wind plate with the air outlet of the centrifugal wind is provided with a flap H piece, which increases the heat dissipating area of the fin, from * in the heat The film group is located near the ===: the windward side of the air outlet of the secret fan is dimmed η jI. The younger brother, the heat sink, can effectively control the cost. At the same time, the flow rate of the airflow flowing through the near-wind side region is far, and the flow velocity of the domain airflow is equal to the flow of the airflow on the near-wind side or the wind-up side in the area on the windward side. Therefore, the airflow generated by the heart 2 can be fully utilized, so that the heat dissipation performance is effectively improved.

When the heat dissipating device is in use, the heat conducting plate 2 is attached to the surface of a heat-generating electronic component and absorbs the heat generated by the heat-dissipating plate 2, and the tube 40 transfers the heat absorbed by the heat-conducting plate 20 to the heat sink group 3〇 first and second The heat sinks 31, 32' are further blown by the airflow generated by the centrifugal fan to the first and second heat sinks 31, 32 and exchange heat with the first and second heat sinks 31 to finally dissipate heat. The heat dissipating post 21 provided on the second side can also directly dissipate part of the heat absorbed by the heat conducting board 20. In the heat dissipating device, a first fin 31 having a flap portion 312 is provided in a region of the wind side 135 of the air outlet n3 of the centrifugal fan 10, and a flap portion 312 between the adjacent first fins 31 and the two - the body 11 311 of the heat sink 31 is spaced apart by a distance, thereby separating the air flow passages of the two adjacent _ heat sink & gates into two parts, and the air flow flows through the two adjacent first heat sinks When the air flow passages of the 31 passages are simultaneously heat-crossed with the two surfaces of the flap portion 312, the heat sink group 30 is located on the near wind side without increasing the integral of the heat sink group 3G. The 135 area is the first - the overall heat dissipation area of the heat sink is increased. In the far side of the air outlet 136 of the centrifugal fan, the second heat sink 32 without the wing portion is used, so that the manufacturing cost of the heat sink group 3 can be effectively controlled. At the same time, the flow rate of the airflow flowing through the near-wind side 135 is greater than the 13-speed of the far wind side, on the equal area, the gas on the near-wind side is the second; the flow is greater than the flow on the far wind side 136. Therefore, the airflow generated by the centrifugal fan can be transferred to full Xiang, and the thermal performance of the filament can be effectively improved. The wing portion 312 of each of the first heat releasing fins 31 is located only in the middle of the air flow passage, thereby partially dividing the air flow passage into two parts, so that the windward side of the air flow passage is not provided with the flap portion 312, so that the near wind side 135 The airflow in the region can smoothly enter the airflow passage between the first fins 31 along the intake section. The airflow is accelerated after being compressed in the middle portion of the airflow passage, so that it can quickly flow out from the air outlet section of the airflow passage. The distance between the far wind segments 316 and 327 of the second flanges 314 and 324 of the first and second heat sinks 31 and 324 and the respective first flanges 313 and 323 is greater than that of the first and first heat sinks 31 and 32, respectively. The distance between the near wind segments 315, 326 of the second flanges 314, 324 and the respective first flanges 313, 323, so that the air flow passage between the first and second heat sinks 31, 32 is at the height of the air outlet section 12 The degree is greater than the outflow section of the height section of the intake section. The test can quickly pass from the airflow to the above-mentioned heat sink, and the first tube 312 of the hot plate 31 is attached to the first flange 313. Under the condition of the size of the bulk and the number of heat sinks, the force of the external force of the ^ chip group can be transmitted downward by the first heat sink 3i^=4G=condensing segment, and the heat pipe 4 is squid scattered” wing portion 312 Effectively, the heat transfer efficiency of the Me hot film is obtained for several years, and the conventional heat pipe is welded by increasing the heat dissipation device of the heat sink area of the heat sink group. The reliability is higher. - In addition, the second heat sink 32 is provided with a flow guiding portion, and the 邛 322 is biased toward the air outlet of the centrifugal fan 1 (1) to make the air flow smoother. The gas between the adjacent two second heat sinks 32 = = production: reducing the impact between the air flow and the second heat sink 32, thereby reducing the heat sink unit 3, the first heat sink 31 The first-folded edge 313 and the second folded edge 314 are located on the same side of the main body portion 3 ιι to understand that the first folded edge 31 of the first heat sink 31 is affixed to On the opposite side of the body portion 311, when the two first heat sinks U are lifted, the 319 of the wing portion 312 of the first heat sink 31 abuts against the second fold between the two first heat sinks 31. In summary, the present invention is in accordance with the requirements of the invention patent, and the patent application is filed according to law. However, it is familiar with the embodiment of the technique of the invention, and the equivalent modification of the π Γ in the spirit of the invention alone. All of them should be covered in the following patents.
