Specific embodiment

Please refer to Fig. 1 and Fig. 2, the better embodiment of electronic device of the present invention, including a bottom plate 10, a circuit board 20, Several fans 30 and an air guide member 40.

Several fixed columns 12 with screw hole 121 are convexly equipped on the bottom plate 10.On the corresponding bottom plate 10 of the circuit board 20 The screw hole 121 of these fixed columns 12 is equipped with several perforation 23.A heat-generating electronic elements 25 are installed on the circuit board 20.These wind Fan 30 is installed on the bottom plate 10.

Referring to figure 3. with Fig. 4, which includes that a horizontally long main body 41 and two are had by what the main body 41 was extended The card base 43 of elasticity.The main body 41 in triangular prism shaped, including a bottom wall 412 and one by the bottom wall 412 front side upwards and backward Tilt the air guiding wall 414 extended.Several length along the air guide member 40 are vertically connected between the bottom wall 412 and the air guiding wall 414 Spend the spaced baffle 416 in direction.These rectangular triangles of baffle 416.The back side edge of the air guiding wall 414, the bottom wall 412 Back side edge and the back side edges of these baffles be located on same vertical plane.The adjacent baffle 416 of 414 face of air guiding wall every two it Between gap 417 offer the ventilation slot 418 in the connection gap 417.Two card base 43 in the form of sheets, respectively by the air guiding wall It is extended back at 414 neighbouring both ends.The middle part of two card base 43 is bent respectively to form the clamping part 431 of an arc in opposite directions. The distance between two clamping part 431 is substantially equal between two fixed columns 12 of these neighbouring fans 30 on the circuit board 20 Distance.The end of two card base 43 is bent respectively to form an inclined guide surface 433 in opposite directions.Each card base 43 is backwards to another card base 43 side is convexly equipped with several tread plates 435 in clamping part 431 between guide surface 433.

Referring once again to Fig. 1 and Fig. 2, when assembling, the circuit board 20 is placed in these fixed columns 12 first, if by Perforation 23 that dry screw 60 is each passed through on the circuit board 20 and the screw hole 121 for locking the correspondence fixed column 12 on the bottom plate 10, The circuit board 20 is fixed on the bottom plate 10.These fans 30 are located at the front of the circuit board 20.The air guide member 40 is placed in this On bottom plate 10 and between the circuit board 20 and fan 30.Make the air guiding wall 414 of the air guide member 40 towards these fans 30, it should Two card bases 43 of air guide member 40 are inserted into the lower section of the circuit board 20, and divide the guide surface 433 of two card bases 43 of the air guide member 40 Two corresponding fixed columns 12 of these neighbouring fans 30 on the circuit board 20 are not abutted.The air guide member 40 is pushed backward, this two draws Guide face 433 gradually slips over the two corresponding fixed column 12 and two card base 43 is driven to move towards generation flexible deformation.Continue to After push the air guide member 40, until two card base 43 clamping part 431 distinguish the face two corresponding fixed column 12, two card base 43 elasticity restore that two clamping part 431 is made to be placed in the two corresponding fixed column 12 respectively.To which the air guide member 40 is fixed in The bottom plate 10.At this point, the back side edge of the air guiding wall 414 of the air guide member 40 is connected to the front side of the circuit board 20, the air guide member 40 These ventilation slots 418 be located at the circuit board 20 heat-generating electronic elements 25 front.

When the electronic device functions, distinguished and admirable a part of these fans 30 blowout directly blows to the top of the circuit board 20, A part is blown to the top of the circuit board 20 along the air guiding wall 414 of the air guide member 40 from bottom to top, this two parts is distinguished and admirable Flow through heat-generating electronic elements 25 on the circuit board 20 and other electron component and to heat-generating electronic elements 25 and other electronics member Part is efficiently radiated.Meanwhile the distinguished and admirable also sub-fraction of these fans 30 blowout passes through the air guiding wall of the air guide member 40 The gap 417 between ventilation slot 418 and baffle 416 on 414 and the lower section for blowing to the heat-generating electronic elements 25 of the circuit board 20, So as to radiate from bottom surface to heat-generating electronic elements 25 and circuit board 20.Since the air guide member 40 will flow most To the distinguished and admirable top stopped and be oriented to circuit board 20 of 20 lower section of circuit board, to improve distinguished and admirable utilization rate and electronic device Radiating efficiency.

When taking out the air guide member 40, being equipped at tread plate 435 for two card bases 43 of the air guide member 40 need to be only pressed in opposite directions, So that the clamping part 431 of two card base 43 is detached from corresponding fixed column 12 respectively, the air guide member 40 can be extracted forward.

In other embodiments, the bottom wall 412 of the air guide member 40 can save.The air guide member 40 can save two card base 43 and be fixed on the bottom plate 10 otherwise, such as locked by buckle between bottom plate 10 or screw.
