Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining。
Consult shown in Fig. 1, the auxiliary radiating device of the present invention, it includes housing 1, top cover 2 and driving mechanism, housing 1 top is provided with opening 3, outside pyrotoxin 4 is arranged on the inside of housing 1, and pyrotoxin 4 also contacts with driving mechanism, and driving mechanism is connected with top cover 2, wherein, driving mechanism is for absorbing the heat of pyrotoxin 4 and producing driving force, and top cover 2 has open position and make position, when the non-adstante febre of pyrotoxin 4, top cover 2 is in the close position, and top cover 2 covers completely on opening 3；When pyrotoxin 4 adstante febre, top cover 2 is in an open position, top cover 2 and opening 3 mutual dislocation or disengaging。
In the present invention, driving mechanism converts the heat that pyrotoxin 4 distributes to driving force, top cover 2 is promoted to move, so that top cover 2 and housing 1 produce to accelerate the gap of air circulation, improve radiating effect, and when pyrotoxin 4 is in low temperature state, top cover 2 can cover completely on opening 3, effectively prevent the entrance of dust。
Specifically, driving mechanism includes cylinder 5, piston 6 and connecting rod 7, the bottom of cylinder 5 contacts with pyrotoxin 4, piston 6 is arranged in cylinder 5, and piston 6 is connected bar 7 and is connected with top cover 2, wherein, in the rodless cavity of cylinder 5, it is additionally provided with liquid 8, after pyrotoxin 4 generates heat, liquid 8 is vaporized and promotes piston 6 to move。In the present invention, the boiling point of liquid 8 is 70 °-80 °, because when this auxiliary radiating device is applied to electronic equipment, the heating temp of the electronic component in electronic equipment is generally less than 100 °, if the boiling point of liquid 8 is too high, then when the heating temp of electronic component is higher, liquid 8 still can not be vaporized and be promoted piston 6 action, does not have effective thermolysis；The boiling point of liquid 8 is too low then, and electronic component somewhat generates heat and will promote piston 6 action, does not have effective dustproof effect。Certainly, when this auxiliary radiating device being applied to other equipment, it is possible to select the liquid of different boiling according to practical situation。
Liquid 8 in the present embodiment can be ethanol, when the temperature of pyrotoxin 4 rises, and when exceeding boiling point (79.8 degrees Celsius) of ethanol, ethanol is acutely vaporized so that the implant in cylinder 5 becomes the alcohol vapour of gaseous state, and volume significantly increases, and produces pressure by piston 6 upwardly, again through connecting rod 7 by top cover 2 jack-up, so that produce bigger space between top cover 2 and housing 1, to promote housing 1 inner air and outer air convection current, thus reaching to improve the purpose of heat radiation。
