As shown in Figure 7, the Audio Frequency Amplifier box 400 that has a heat-dissipating part On/Off device 300 has a plurality of heat-dissipating parts.Label 410 each heat-dissipating part of expression.The position of these heat-dissipating parts all is corresponding with the position of those On/Off plates of the first On/Off arrangement components 304 and the second On/Off arrangement components 306.
Various details the 3rd embodiment.
Fig. 9 is a diagram is finished the On/Off operation by the heat-dissipating part On/Off device shown in Fig. 7 a view.For simplicity, only illustrate a moving member 320.Description to the manner of execution of moving member 320 is applicable to another moving member.Here, will describe be contained in first dissipating cover 361 on the relevant operation of heat-dissipating part On/Off device 300.A four-headed arrow A indicates the movement direction of moving member 320.
At first, if do not make the Audio Frequency Amplifier energising, produce the parts (schematically illustrating with label 500) of heat, for example power supply will not produce heat.Therefore, do not have heat to pass to shaping memory alloy spring 342, like this, by helical spring 341, the moving member 320 of heat-dissipating part On/Off device 300 is in A
1The position.As shown in Figure 9, be in A when moving member 320
1During the position, described a plurality of heat-dissipating parts are shut with their corresponding respectively a plurality of On/ Off plates.Label 410 and 320 is represented each heat-dissipating part and On/Off plate respectively.
When making the Audio Frequency Amplifier energising, heating component 500 (as power supply) is emitted heat.Liberated heat in turn heats first dissipating cover 361 and fixed block 350.When fixed block 350 was heated, shape memory alloy spring 342 also was heated, and like this, its temperature raises.In case the temperature of shape memory alloy spring 342 reaches a specific temperature, shape memory alloy spring 342 is retracted to a shape of having remembered.The contraction of shape memory alloy spring 342 is moved to the left moving member 320.At this moment, helical spring 341 stretches left.Simultaneously, moving member 320 is in A
2On the position.As shown in Figure 9, be in A at moving member 320
2The position time, by with the moving of the corresponding a plurality of On/Off plates of heat-dissipating part, open described a plurality of heat-dissipating part.
In addition, if cut off the power supply of Audio Frequency Amplifier, the temperature of shape memory alloy spring 342 descends.When the temperature of shape memory alloy spring 342 when a specific temperature descends, shape memory alloy spring 342 loses its shape memory.At this moment, by the restoring force of helical spring 341, moving member 320 moves right.When the restoring force of helical spring 341 disappeared, moving member 320 was in position A
1Like this, utilize described a plurality of On/Off plate to close described a plurality of heat-dissipating part.
In addition, the movement direction of another moving member is identical with moving member 320.Because the manner of execution of another moving member is identical with moving member 320, has omitted the description to another moving member manner of execution.
Therefore, heat-dissipating part On/Off device of the present invention has prevented that foreign matter from entering Audio Frequency Amplifier inside, and to the hot air that effluxes the big device of bulk storage inside.
Although the present invention has been carried out detailed displaying and description with reference to its certain embodiments, those skilled in the art should be realized that, without prejudice to the situation that exceeds the spirit and scope of the present invention defined by the claims under, can carry out various changes to form of the present invention and details.
