This pallet 13 comprises the first surface 131 and the second surface 132 that are oppositely arranged, contiguous this cover plate 123 of this first surface 131.This pallet 13 defines the central shaft on vertical this first, second surface 131,132, and this pallet 13 rotates relative to this bracket 12 taking this central shaft as rotating shaft.One cylindric reference column 133 is set on this first surface 131, this reference column 133 is coaxial with this central shaft, sheathed this reference column 133 peripheries that are fixed on of another cylinder-shaped magnet 164, the cylinder-shaped magnet 163 and the sheathed cylinder-shaped magnet 164 that is fixed on reference column 133 peripheries that are fixed on groove 1212 produce the magnetive attraction repelling each other.This first surface 131 also arranges one second annular groove 136, the setting corresponding to this first ring connected in star 1232 of this second annular groove 136, this second annular groove 136 is in order to fix another annular magnet 162, and the annular magnet 161,162 being arranged in first, second annular groove 1232,136 produces the magnetive attraction repelling each other.The position of the corresponding reference column 133 of this second surface 132 arranges one first circular groove 137, in order to fix a discoideus magnet 165.
Multiple the second through holes 135 run through this first, second surface 131,132.And the vertical line on each the second relative this first, second surface 131,132 of through hole 135 is obliquely installed (consulting Fig. 3).This second through hole 135 is centered around outside this reference column 133 to surround into the mode of circumference, and the plurality of the second through hole 135 is at least around this reference column 133 1 weeks.The circumference being surrounded into by this second through hole 135 is corresponding with the circumference being surrounded into by this first through hole 1250.In the present embodiment, the density of this second through hole 135 on its circumference is greater than the density of the first through hole 1250 on its circumference.This second through hole 135 outside this reference column 133 from the inside to the outside around three weeks.The second through hole 135 of each circumference is distributed in outside reference column 133 according to Jun Yun tilt angle.Be arranged on three weeks every three the second through holes 135 be in alignment with each other and be positioned on the line stretcher of radius of this reference column 133.
This netted upper cover 15 comprises wire side 152 and is arranged on wire side 152 edges vertically extending support 153, and contiguous pallet 13 second surfaces 132 of this wire side 152 arrange.One second circular groove 157 is also set on this wire side 152, and this second circular groove 157 is in order to fix another discoideus magnet 166.The discoideus magnet 165,166 being fixedly installed in this first, second circular groove 137,157 produces the magnetive attraction repelling each other.This netted upper cover 15 is fixed on bracket 12 by this support 153.In the present embodiment, this support 153 comprises connecting portion 1531 and fixed part 1532, and this connecting portion 1531 is L-shaped with this fixed part 1532, and connecting portion 1531 is connected with wire side 152.This netted upper cover 15 is fixed to the cover plate 123 of bracket 12 by fixed part 1532.
See also Fig. 4-5, while assembling this heat abstractor 1, annular magnet 161,162 is separately fixed in this first, second annular groove 1232,136.Cylinder-shaped magnet 163 is fixed in the groove 1212 of bracket 12 base plates 121, sheathed reference column 133 peripheries that are fixed on of cylinder-shaped magnet 164.Discoideus magnet 165,166 is separately fixed in this first, second circular groove 137,157.Pallet is placed on the cover plate 123 of bracket 12, the reference column 133 and the cylinder-shaped magnet 164 that are set-located are limited in the cylinder of cylinder-shaped magnet 163.Cover netted upper cover 15, make the support 153 of netted upper cover 15 be positioned at the peripheral of pallet 13 and by spacing pallet 13 receiving space 150 defining at this netted upper cover 15 and bracket 12.The circumference at these the first through hole 1250 places is corresponding with the circumference at the second through hole 135 places.
Owing to producing the magnetive attraction repelling each other between annular magnet 161,162, between cylinder-shaped magnet 163,164, produce the magnetive attraction repelling each other, between discoideus magnet 165,166, produce the magnetive attraction repelling each other, thereby can relatively freely pallet 13 be supported in receiving space 150, this pallet 13 can be relative at this, receiving space 150 is interior rotates freely.
The heat abstractor 1 of this case is without providing electric power to dispel the heat, while adopting the heat abstractor 1 of this case to dispel the heat to electronic installation 19 (consulting Fig. 6), heat abstractor 1 is fixed on the housing of electronic installation 19, fixed form can adopt to fix and fix, and also can adopt screw locking.In the present embodiment, the draw-in groove 120 forming is fixed to the housing of electronic installation 19, thereby dispels the heat by this heat abstractor 1 on heat abstractor 1 bracket 12 base plates 121.There is temperature difference inside and outside the housing of electronic installation 19 time, because temperature contrast can make density difference between air, the volume expansion of being heated, density reduces, outwards loss gradually, and replenish air that position is lower by environment temperature, density is larger in it it, the air outside loss of being heated again supplementing, air around comes again to supplement, so circulation endlessly, by heat by the Bas Discharged flowing.And when the temperature difference T>0.5 in electronic installation 19 housings and outside housing spends, when heated air is progressed into heat abstractor 1 and is passed through heat abstractor 1 outside loss by the first through hole 1250 on the bracket 12 of heat abstractor 1, enter after heat abstractor 1 at the air being heated, the air of discharging through the second through hole 135 of pallet 13, due to the relative pallet 13 first of the second through hole 135, second surface 131, 132 vertical line is obliquely installed, therefore the mobile air in the second through hole 135 produces side force to pallet 13, thereby pallet 13 is rotated relative to bracket 12, and the rotation of pallet 13 also can further promote Air Flow, and the rotation of pallet 13 causes inside and outside air velocity difference and produces pressure differential, accelerate hot gas and drive outflow enclosure interior, thereby greatly improve the effect of heat radiation.
The heat abstractor 1 of this case is simple in structure, and without utilizing driven by power, the convection current producing by the temperature difference and the second through hole 135 being obliquely installed, the side force driving tray 13 that the air stream being heated is produced pallet 13 through the second through hole 135 rotates relative to bracket 12, further improve radiating effect, relatively increase the life-span of heat abstractor 1.
