[The conventional method is attached to the surface of the heat-generating electronic component. A fin set is disposed, and then a fan is disposed on the fin set, and the fin group is forcibly dissipated by the cold air flow generated by the fan, thereby dissipating heat generated by the heat generating electronic component. The conventional notebook computer generally includes a bottom plate and a cover plate opposite to the bottom plate. The bottom plate and the cover plate are combined with each other to form a sealed receiving space. A fan is received in the receiving space, and the fan generally includes a cover. a fan frame and an impeller disposed in the fan frame, and the fan frame of the fan is provided with upper and lower air inlets, and the fan and the fan are mounted on the electronic device, and the upper and lower air inlets of the fan and the electronic device are The cover and the bottom plate have a certain distance to ensure the air inlet condition of the fan. However, for the height of the system, the distance between the air inlet of the fan and the cover and the bottom plate of the notebook computer will be reduced. The traffic will also be greatly reduced. Therefore, how to ensure that the 200949515 notebook computer has better heat dissipation performance under the condition of reducing the size of the notebook computer has become an inevitable trend of current development. SUMMARY OF THE INVENTION It is necessary to provide a heat sink having a lower height without being able to be used for a computer and a type of heat sink. θ, a type of computer, including a bottom plate, a cover plate, a heat-generating electronic 7C device, and a heat-dissipating farm, the bottom plate and a housing having a receiving space, the heat-generating electronic component and heat dissipation; a fin group connected to the heat pipe and disposed on the fin== fan, the fan and the fin set are disposed on the bottom plate, wherein the sidewall has an air outlet and a wall and a wall Adjacent, the airflow enters from the air inlet and the air outlet and the fin are discharged from the air outlet and blown toward the fin group. A heat dissipating device includes a heat pipe, a fin group connected to the heat pipe, and a fan disposed on the side of the fin group, the fan including a side wall, the side wall opening=an air outlet and an air inlet, The air outlet is adjacent to the tab group, and the thin 4 person vents are taken in from the air outlet and blown to the tab group. Compared with the prior art, the loose track device in the notebook computer changes the airflow direction by changing the setting of the fan π of the fan, and the (four) setting can be used without considering the bottom plate of the notebook computer, the cover plate and the fan air inlet. The distance 'can adapt to the needs of thinner notebook computers, so that its heat is effectively distributed. / [Embodiment] 7 200949515 A notebook computer having a heat dissipating device of the present invention will be described in detail below with reference to the accompanying drawings. 1 to 3 show a preferred embodiment of the notebook computer of the present invention. The notebook computer 1000 includes a bottom plate 100, a heat dissipation device 200 disposed on the bottom plate 100, and a cover plate 300 disposed on the heat dissipation device 200. The cover plate 300 and the bottom plate 1 are combined to form a receiving space (not shown). The heat sink 200 is received in the receiving space. The heat sink 200 is used to heat the electronic components disposed in the receiving space. Cpu (not shown) and so on. The heat sink 200 includes a heat absorbing plate 10, the lower surface of which is in contact with the heat generating electronic component for absorbing heat thereof, and the upper surface of the heat absorbing plate 10 is connected to one end of the heat pipe 20 'the other end of the heat pipe 20 The bent extension is connected to a fin set 30, and a fan 40 is disposed on one side of the fin set 30. The fin group 30 is disposed at a position of one end of the bottom plate 100. The side wall 302 of the cover plate 300 is provided with a vent 304 corresponding to the position of the fin group 30. The size of the vent 304 and the fin group 30 are The size is quite. The fan 40 includes a frame 42 and an impeller 44 disposed in the frame 42. One side of the fan frame 42 is provided with an air outlet 46' corresponding to the position of the fin group 30. The opposite side of the fan frame 42 is opposite to the air outlet 46. The fan frame 42 includes a substrate 420 and a sidewall extending vertically downward from the substrate 420. The air inlet 48 and the air outlet 46 are defined on the sidewall, and the sidewall is divided into the first wall portion 422. And the second wall portion 424, the first and second wall portions 422, 424 are oppositely disposed on opposite sides of the air outlet 46 and the air inlet 48. In this embodiment, the substrate 420 has an arc 8 200949515 side 4202 and two straight sides 4204, 4206 '. The air outlet 46 is disposed at a position of the straight side 4204, and the second wall portion 424 is formed by another straight side 4206 and An arcuate edge 4202 that engages with the straight edge 4206 extends downwardly. The first wall portion 422 is formed by a downwardly extending portion of the curved edge 4202 opposite to the straight edge 4206. The first wall portion 422 is adjacent to the first wall portion 422. A tongue portion 4260 is formed inwardly from the tuyere 46. The impeller 44 includes a hub 440 and a plurality of blades 442' disposed around the hub 440. The hub 440 includes a circular bottom surface 4420 and an annular wall 4422 extending vertically upward from the periphery of the bottom surface 4420. The vane 442 extends radially outwardly, and its end portion is bent in a clockwise direction, and the vane 442 is evenly distributed around the periphery of the wheel portion 440 so that the impeller 44 does not sway when rotated. Each of the vanes 442 is fixedly connected by a ring 444. In the present embodiment, the number of the rings 444 is four, the four rings 444 are disposed around the hub 440, and the adjacent rings 444 are spaced apart from each other. The top and bottom surfaces of the blades 442 and the bottom surface, that is, the blades 442 The four corners are connected to the four rings 444 in a one-to-one manner, with the vanes 442 located in the area surrounded by the ring 4. The impeller 44 connects the annular wall 4422 of the hub 440 to the ring 444 of the bottom surface of the inner end of the blade 442 by a plurality of ribs 446. Of course, the structure of the impeller 44 is not limited to the case of the present embodiment, but may be applied to the structure of the impeller in the other four buy-out fans. For example, the vane 442 may be coupled to the hub 440 by a disc. In this embodiment, the arrangement of the structure fan 40 can directly attach the cover 3 of the notebook computer 1 to the substrate 420 of the fan frame 42 when the notebook computer 1000 is assembled. Instead of leaving a blank 9 200949515 gap, this can effectively reduce the thickness of the notebook 1000. In addition, the heat-generating electronic components and fin sets 30 of the notebook computer 1000 are located on the same line as the air inlets 48 and the air outlets 46 of the fan 40, and the hot airflow around the heat-generating electronic components can be directly passed through the fan 40. The tuyere 48 is sucked in and then blown out from the air outlet 46. In addition, the heat generated by the heat-generating electronic component is transmitted to the heat pipe 20 through the heat absorbing plate 10, and then transmitted to the fin group 30 via the heat pipe 20, and the airflow blown from the air outlet 46 through the fan 40 flows through the fin group 30, and then ventilated. Port 304 ® removes the heat from fin set 30 for heat dissipation. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law.
