The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As shown in fig.1, the auxiliary radiating device of the present invention, it includes housing 1, top cover 2 and drive mechanism, and housing 1 pushes up
Portion is provided with opening 3, and outside pyrotoxin 4 is arranged on the inside of housing 1, and pyrotoxin 4 is also in contact with drive mechanism, driving machine
Structure is connected with top cover 2, wherein, drive mechanism is used to absorb the heat of pyrotoxin 4 and produces driving force, and top cover 2, which has, to be opened
Position and closing position, when 4 non-adstante febre of pyrotoxin, top cover 2 is in the close position, and top cover 2 covers in opening 3 completely；When
The adstante febre of pyrotoxin 4, top cover 2 is in an open position, top cover 2 and the mutual dislocation of opening 3 or disengaging.
In the present invention, the heat that pyrotoxin 4 distributes is converted into driving force by drive mechanism, promotes top cover 2 to move, from
And top cover 2 is produced the gap that can accelerate air circulation with housing 1, radiating effect is improved, and it is in low temperature shape in pyrotoxin 4
During state, top cover 2 can cover in opening 3 completely, effectively prevent the entrance of dust.
Specifically, drive mechanism includes cylinder 5, piston 6 and connecting rod 7, and the bottom of cylinder 5 is in contact with pyrotoxin 4, living
Plug 6 is arranged in cylinder 5, and piston 6 is connected through connecting rod 7 with top cover 2, wherein, it is additionally provided with liquid in the rodless cavity of cylinder 5
8, after pyrotoxin 4 generates heat, liquid 8 vaporizes and promotes piston 6 to move.The boiling point of liquid 8 is 70 ° -80 ° in the present invention,
Because when this auxiliary radiating device is applied into 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, when the heating temp of electronic component is higher, liquid 8, which can not still vaporize, promotes piston 6
Action, does not have effective thermolysis；And the boiling point of liquid 8 is too low then, electronic component, which somewhat generates heat, will promote piston 6 dynamic
Make, do not have effective dustproof effect.Certainly, can be according to actual feelings when this auxiliary radiating device being applied into other equipment
Condition selects the liquid of different boiling.
Liquid 8 in the present embodiment can be ethanol, when the temperature rising of pyrotoxin 4, and more than the boiling point (79.8 of ethanol
Degree Celsius) when, acutely vaporization causes the filler in cylinder 5 to be changed into gaseous alcohol vapour to ethanol, and volume significantly increases,
Produce pressure to push up piston 6, then jacked up top cover 2 by connecting rod 7, so that being produced between top cover 2 and housing 1
Larger space, to lift the inner air and outer air convection current of housing 1, so as to reach the purpose for improving radiating.
As shown in fig.2, in one of embodiment of the present invention, top cover 2 and 1 split type connection of housing, connecting rod 7
Top is connected with the lower surface of top cover 2, and when piston 6 moves up, top cover 2 moves straight up, and the shape between housing 1
It is into symmetrical two the first gaps 9, the advantages of this structural formula：1), good heat dissipation effect, two the first gaps 9 can be simultaneously
Radiated, improve the circulating rate of air；2), top cover 2 and housing 1 is easy to assembly, avoids assembling work, reduce plus
Work process.
As shown in fig.3, in an alternative embodiment of the invention, side and the housing 1 of top cover 2 are hinged, connecting rod 7
Top and the lower surface of top cover 2 are hinged, and when piston 6 moves up, top cover 2 is in rotary moving, and is formed between housing 1
Two gaps 10.The advantages of this structural formula, is：Under the equal volume variable condition caused by the phase transformation of liquid 8, this mode energy
Further lift the stroke of piston 6 and improve the bearing capacity of piston 6, so as to expand radiating space, improve radiating efficiency.
In the present invention, pyrotoxin 4 should not be directly contacted with cylinder 5 because of reasons such as shape, states, therefore, pyrotoxin
Fin 11 is additionally provided between 4 and the bottom of cylinder 5, by fin 11 can by the heat maximum magnitude of pyrotoxin 4 and
When be quickly sent in cylinder 5, make cylinder 5 liquid 8 produce phase transformation, so as to improve the sensitivity of device.Preferably, in order to
Ensure heat-conducting area and heat transfer efficiency, the sectional area of fin 11 is more than the bottom section product of cylinder 5.
As shown in fig.4, a kind of home electronics, it includes the auxiliary radiating device of any one of such scheme, also
Including circuit main board 12, circuit main board 12 is arranged in the housing 1 of heat abstractor, and drive of the circuit main board 12 also with heat abstractor
Motivation structure is in contact.Wherein, circuit main board 12 produces heat, passes through circuit at work equivalent to pyrotoxin 4, circuit main board 12
Mainboard 12 transfers heat to drive mechanism, and generation driving force promotes top cover 2 to move after drive mechanism absorbs heat, so as to
Top cover 2 is set to make to produce larger gap between top cover 2 and housing 1 relative to the mutual dislocation of open top 3 of housing 1 or disengaging,
To lift the convection current of the inner air and outer air of housing 1, and then improve the purpose of radiating, the present invention is not required to increase extra radiating electricity
Road, therefore extra thermal source and power consumption will not be introduced, and covered completely in 12 non-adstante febre of circuit main board, top cover 2
In opening 3, it is possible to reduce the entrance of external dust, so as to improve the service life of electronic equipment.
More than, be only the present invention embodiment, but protection scope of the present invention is not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should be all included within the scope of the present invention.Therefore, protection of the invention
Scope should be determined by the scope of protection defined in the claims.
