図１を参照し、実施形態に係る熱音響システム１の構成を説明する。中央の熱音響機体２は、共鳴管９とその内部に蓄熱器５を備え、一端には発電機６を付設している。発電機６は共鳴管９から発生した音波振動により発電を行うリニア発電機である。
The configuration of the thermoacoustic system 1 according to the embodiment will be described with reference to FIG. The thermoacoustic body 2 at the center is provided with a resonance pipe 9 and a heat accumulator 5 inside thereof, and a generator 6 is attached to one end. The generator 6 is a linear generator that generates electric power by the sonic vibration generated from the resonance tube 9.
本実施例では、熱音響機体２ごとにレンズ８を備える。レンズ８を通した太陽熱により熱音響機体２の蓄熱器５の一端を加熱する。これにより蓄熱器５に大きな温度勾配を生じさせる。温度勾配を利用した熱音響効果によって発電機６は動作する。
In the present embodiment, the lens 8 is provided for each thermoacoustic body 2. The solar heat passing through the lens 8 heats one end of the heat accumulator 5 of the thermoacoustic body 2. Thereby, a large temperature gradient is generated in the heat accumulator 5. The generator 6 operates by the thermoacoustic effect using a temperature gradient.
本発明ではさらに蓄熱器５の他端を、別の熱音響機体２に付設したヒートポンプ７の冷却作用によって冷却することを特徴とする。図示左右の熱音響機体２は上記同様に共鳴管９とその内部に蓄熱器５を備えており、それぞれの蓄熱器５の一端はレンズ８で集光した太陽熱によって加熱される。各共鳴管の熱音響効果で生じた音波振動から逆スターリングサイクルによって冷却作用を生じさせ、ヒートポンプ７を駆動する。
The present invention is further characterized in that the other end of the heat accumulator 5 is cooled by the cooling action of a heat pump 7 attached to another thermoacoustic body 2. Similarly to the above, the left and right thermoacoustic bodies 2 are provided with the resonance tube 9 and the heat storage unit 5 therein, and one end of each heat storage unit 5 is heated by the solar heat collected by the lens 8. From the sound wave vibration generated by the thermoacoustic effect of each resonance tube, the cooling action is generated by the reverse Stirling cycle to drive the heat pump 7.
右側のヒートポンプ７は中央の蓄熱器５の他端側を冷却しており、これによって該蓄熱器５にさらに大きな温度勾配を生じさせる。温度勾配が大きいことは、より大きな音波を生じさせることになるので、発電機６の発電量を増加することができる。
The heat pump 7 on the right side cools the other end side of the central heat accumulator 5, thereby causing the heat accumulator 5 to generate a larger temperature gradient. Since a large temperature gradient will generate a larger sound wave, the power generation amount of the generator 6 can be increased.
さらに、左側のヒートポンプ７は、発電機６を冷却している。発電機は駆動時の発熱によって効率が低下するため、このように冷却することは発電効率の向上に寄与する。
Furthermore, the heat pump 7 on the left side cools the generator 6. Since the efficiency of the generator is reduced by heat generation during driving, such cooling contributes to the improvement of the power generation efficiency.
従来、発電及び冷却をそれぞれ行う熱音響機関が提案されていたが、本発明のように冷却作用によって発電効率を向上させることは提案されていない。熱音響効果では発電及び冷却が効率的に行える特徴を有しており、本発明のような組み合わせは特に相乗的な効果を有している。
また、必ずしも発電機や蓄熱器を冷却することに用いなくても、一般に電力消費時には機器による発熱が課題となることから、発電と同時に冷却作用を及ぼすシステムの提供は極めて有効である。 Conventionally, thermoacoustic engines that respectively perform power generation and cooling have been proposed, but it has not been proposed to improve power generation efficiency by the cooling action as in the present invention. The thermoacoustic effect is characterized by efficient power generation and cooling, and the combination as in the present invention has a particularly synergistic effect.
In addition, even if it is not necessarily used for cooling a generator or a heat storage device, heat generation by the device is generally a problem at the time of power consumption, so it is extremely effective to provide a system that exerts a cooling action simultaneously with power generation.

The present invention is characterized in that power generation and cooling can be simultaneously performed while using heat from the same heat source for heating the heat storage sections of a plurality of thermoacoustic vehicles.
