Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1 to Fig. 3, fan wall 100 of the present invention comprises the fan modules 30 of nine arrangements in matrix, and each fan module 30 comprises the wind scooper 36 that fan 34 and that a fixed frame 32, is installed on fixed frame 32 side is fixed on fixed frame 32 opposite side.This wind scooper 36 is made up of electromagnetic shielding material, shielding electromagnetic radiation.
This fixed frame 32 is foursquare framework, and comprise the first relative side 320 and the second side 330, this first side 320 and the second side 330 are respectively equipped with a square opening.First side 320 of this fixed frame 32 extends to form four mounting panels 321 be mutually connected respectively in opposite directions in two of its opening relative edges, and set to the concave in the middle part of each mounting panel 321 formation one circular arc.An installing hole 322 is offered in the junction of every two mounting panels 321.The corner place of this fan 34 offers the screw 340 corresponding with installing hole 322 respectively.During installation, insert in this fixed frame 32 by the opening of the second side 330 of fan 34 self-retaining frame, screw 50 locks screw 340 through installing hole 322, fan 34 is fixed on the first side 320 of fixed frame 32.
Please with reference to Fig. 4 to Fig. 6, this wind scooper 36 comprises four installation portions 362 without exception vertically extended to form in foursquare base plate 360, from the top of this base plate 360 and bottom respectively to side and the cover body 363 outwards projecting formation from this base plate 360 opposite side.
This cover body 363 comprises some to arrange at equal intervals and jointly around the circular wind deflector 364 of a central shaft and the some dividing plates 366 be connected with these wind deflectors 364 that outwards arrange in emitting shape from this central shaft.Be provided with a through hole 361 in the middle part of this base plate 360, outermost wind deflector 364 is vertically set on this through hole 361 edge.Every two wind deflectors 364 be spaced apart 0.5cm, in the present embodiment, angle between every two adjacent dividing plates 366 is 30o, also can be any angle between 20o ~ 60o, the height of this cover body 363, wind deflector 364 and dividing plate 366 is 2cm, and the thickness of this wind deflector 364 and dividing plate 366 is 0.3cm.
Contiguous second both sides of the edge, side 330 of the end face of this fixed frame 32 and bottom surface offer two installing holes 332 respectively.The inner vertical of each installation portion 362 projects a protruded stigma 368, protruded stigma 368 offers the screw 367 that runs through this installation portion 362 vertically, during installation, installation portion 362 is stretched in the second side 330 of fixed frame 32, and make screw 367 just to the installing hole 332 corresponding with it, use screw 50 to lock through installing hole 332 the second side 330 that wind scooper 36 is fixed on fixed frame 32 by screw 367.
