Four radiating parts 5 of 4 side of shell, the first through hole 6 on any radiating part 5 are set to the first through hole 6 relatively
The second through-hole 7 on another radiating part 5 being arranged.Four radiating parts 5 join end to end, four radiating parts 5, institutes
It states heat dissipation laminate 2 and the shell 4 surrounds a cavity 10 jointly.Several heat dissipation channels 3 by 10 this side of cavity heat dissipation laminate
2 extend to form several fins to cavity 10, to be formed.The fin is conducive to quickly distribute heat to the sky in cavity 10
In gas.It is equipped with water-proof ventilated device 8 in the first through hole 6, is equipped with fan 9 in second through-hole 7.The heat dissipation channel 3
One end connects the water-proof ventilated device 8, and the other end connects the fan 9, constitutes the channel of air circulation, advantageously forms certainly
The dynamic circulatory system.The height of the heat dissipation channel 3 is less than the heat dissipation laminate 2 and arrives the distance between described shell 4, the heat dissipation
If the height in channel 3 is arranged excessively high, it is connected to the medial surface of the shell 4, then is entered cold inside the cavity 10
Air will be limited to, and be unfavorable for radiating, and both can be air circulation so the height of the heat dissipation channel 3 is suitably reduced
Smoothly channel is provided, while hot and cold air can also be made without limitations, reaches better heat dissipation effect.The heat dissipation laminate 2
Area can greater than, equal to or less than the shell 4 area, between the radiating part 5 described in this way and the shell 4 just be in one
Fixed angle, this angle can be arbitrary value, and the area for the laminate 2 that radiates described in the present embodiment is greater than the face of the shell 4
Product, in obtuse angle, specifically, preferably 135 ° in the present embodiment, this design keeps tablet computer overall structure more beautiful to the angle
It sees, the fan 9 and the water-proof ventilated device 8 can stash, and surface can't see.The heat dissipation laminate 2 can reinforce plate
Additional cooler is played the role of in the heat dissipation of computer internal electronic component, specifically, slim aluminium is used described in the present embodiment
Alloy sheets, light-weight, thermal coefficient is high, preferably tablet computer internal heat can be directed in the cavity 10, and in institute
It states and is provided with several through-holes 21 on heat dissipation laminate 2, scattering and disappearing for 1 internal heat of plate ontology can be reinforced.The utility model knot
Structure design is simple, it is easy to accomplish, small in size, heat sinking back-plate is directly integrally designed with plate ontology, easy to carry and use, heat dissipation
Effect is good, while can balance tablet computer external and internal pressure, prevents moisture and dust from entering inside tablet computer.
Referring to Fig. 1, the first through hole 6 is identical as the shape of the water-proof ventilated device 8, can be arbitrary shape
Shape, since circle is easier to form, structure is beautiful, is easily installed, while not easily causing defect after circular configuration molding, so
First through hole 6 described in the present embodiment and 8 circular of water-proof ventilated device.Second through-hole 7 theoretically can be to appoint
Shape of anticipating uses rectangle in the present embodiment to preferably install the fan 9.The fan 9 is aerofoil fan, axis stream wind
The exhausting effect of fan is good, and muting function is good.The water-proof ventilated device 8, which is separately positioned on the fan 9, to be oppositely arranged
On two radiating parts 5, convenient for forming cross-ventilation, reinforce heat dissipation effect.
Fig. 4 and Fig. 5 are please referred to, the water-proof ventilated device 8 includes: that the waterproof on 6 inner wall of first through hole is saturating
Air film 81, the support frame 82 set on 81 inside of waterproof ventilated membrane.81 aperture of waterproof ventilated membrane is greater than gas in air
Molecular diameter, and it is less than hydrone diameter, it can guarantee to realize that gas molecule exists under the premise of 81 waterproof of waterproof ventilated membrane
It swaps inside and outside the cavity 10, to guarantee 10 internal and external pressure balance of cavity, while being swapped in gas molecule
When can also realize the balance of 10 internal-external temperature difference of cavity.The area of the waterproof ventilated membrane 81 is greater than the first through hole 6
Area can guarantee that the waterproof ventilated membrane 81 covers the first through hole 6 in this way, avoid influencing waterproof and breathable there are gap
Performance.Gluing oxidant layer 83 is equipped between 5 inner wall of the radiating part around the waterproof ventilated membrane 81 and the first through hole 6.
The area of support frame as described above 82 is greater than the area of the waterproof ventilated membrane 81, can preferably fix the waterproof ventilated membrane in this way
81, support frame as described above 82 is fixed on 5 inner wall of the radiating part around the first through hole 6 by sealant 84, using glue
Stick and sealant are fixed, easy to operate, seal good fixing effect, will not additionally increase the weight of the heat sinking back-plate.
Support frame as described above 82 includes a support portion 821, is fixed, is prevented to the waterproof ventilated membrane 81 by the support portion 821
The waterproof ventilated membrane 81 falls off damage in the inner air and outer air process of circulation repeatedly, extends making for the waterproof ventilated membrane 81
Use the service life.The shape of the support portion 821 can have any shape, such as can be cross or groined type, and the present embodiment is excellent
Cross is selected, cross-shaped structure design is simple, and support effect is good.
In use, the fan 9 is powered on, the hot wind in the cavity 10 is taken out of by the fan 9；Thus
The cavity internal pressure is reduced, makes the cavity 10 is inside and outside to form pressure difference, so that cool exterior air passes through the waterproof and breathable
Enter in the cavity 10 after 8 dust removal by filtration of device；Cold air is by the drive of 9 draft of fan across the entire cavity
10, the heat that tablet computer distributes is taken away, hot wind is discharged eventually by the fan 9；Thus automatic cycle forms circulation
Air-flow is reached for the purpose of tablet computer cooling.What heat dissipation channel 3 described here played the role of is water conservancy diversion, in the fan 9
Draft effect under, part cold air will be accelerated along the heat dissipation channel 3, accelerate the exchange of heat, another part
Cold air will be trapped in the cavity 10 and slowly move, and cooling simultaneously replaces the hot-air in the cavity 10, reinforce heat dissipation effect
Fruit.
In conclusion integrated radiating backboard is arranged at the tablet computer back side in the utility model, tablet computer heat dissipation is realized
While prevent dust and moisture from entering inside backboard；Using fan and water-proof ventilated device in combination with cavity and heat dissipation channel
Automatic cycle heat dissipation system is constituted, good heat dissipation effect is conducive to row pressure；Waterproof ventilated membrane was both facilitated using adhesive mounting method
Operation, and save cost；The fixation of support frame can prevent waterproof ventilated membrane from falling off and damaging simultaneously；Between support frame and radiating part
It is sealed using sealant, easy to operate, sealing and stationarity are good.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
