Abstract
The present invention discloses a heat sound refrigerator by using noise as a driving source. The present invention is orderly connected with a noise collector, a heat exchanger at the hot end, a heat sound plate stack, a heat exchanger at the cold end, a resonating tube and a resonant cavity. The present invention uses noise as the driving source, and a noise source has multiple kinds and comprises an electroacoustic source (such as an improved electric loudspeaker, a piezoelectric loudspeaker and a high frequency linear motor driving sound generator), a heat sound source (a standing wave type heat sound driver and a travelling wave type heat driver), a pneumatic sound source, etc. The sound sources have a common characteristic that the sound sources need to consume usable energy sources (such as electrical energy, heat energy, dynamic energy, etc.) The present invention has the aim for using omnipresent noise in daily environment, and the noise is collected to be used for driving the heat sound refrigerator, and waste is changed into valuables; thus, great practical value is realized. A unidirectional reflection type oxhorn-shaped sound channel is used for collecting and amplifying the noise in the environment, and accordingly, a sound pressure level is enhanced so as to achieve the requirements of a heat sound refrigerator system.
Description
Technical field
The present invention relates to a kind of is the hot sound refrigerating machine of drive source with the noise.
Background technology
Thermoacoustic refrigeration is to utilize thermoacoustic effect to carry out pump heat, promptly because the interaction between the fluid of solid dielectric in the sound field and vibration, make in the solid wall surface certain limit equal hot-fluid when producing against the acoustic propagation direction, and in this zone the phenomenon of absorption sound merit.The thermoacoustic refrigeration effect obviously depends on the existence of sound wave in the system, thereby primary work is to produce sound wave.Generally adopt at present through improved dynamic loudspeaker or piezo-electric loudspeaker and high frequency linear electric motors driving acoustic generator.In addition, the pneumatic type of employing sonic generator is also arranged.Yet their something in common is to need to consume the useful energy to obtain merit.In surroundings, noise is ubiquitous, and especially in some specific industrial occasions, noise level even reach the intolerable stage of people if can collect noise to turn waste into wealth be used to drive hot sound refrigerating machine, will have great practical value.
Summary of the invention
The purpose of this invention is to provide a kind of is the hot sound refrigerating machine of drive source with the noise.
It is connected with that noise gatherer, hot end heat exchanger, heat sound plate are folded in turn, cool end heat exchanger and resonatron resonant cavity.
The present invention is drive source with the noise, and the noise source kind is a lot, comprises electroacoustic source (for example improved dynamic loudspeaker, piezoelectric speaker and high frequency linear electric motors drive acoustic generator), hot sound source (standing wave type and travelling-wave type thermo acoustic engine) and pneumatic sound source etc.Their common ground is all to need to consume the useful energy (as electric energy, heat energy and kinetic energy etc.).The present invention is intended to utilize noise ubiquitous in surroundings, and it is collected is used to drive hot sound refrigerating machine, turns waste into wealth to reach, and realizes its great practical value.Adopt the ox horn type sound channel of regular reflection formula, the noise in the environment is collected and amplification, thereby improve sound pressure level to reach the requirement of thermoacoustic refrigeration system.
Description of drawings
Fig. 1 is to be the hot sound refrigerating machine structural representation of drive source with the noise;
Fig. 2 is that noise gatherer noise of the present invention is collected the amplification principle schematic diagram.
The specific embodiment
With the noise be that the hot sound refrigerating machine of drive source is connected with that noise gatherer 1, hot end heat exchanger 2, heat sound plate are folded 3 in turn, cool end heat exchanger 4 and resonatron 5 resonant cavity 6.Noise gatherer 1 is " ox horn type " sound channel, and is provided with the noise gatherer arrival end 7 and the noise gatherer port of export 8.
The noise gatherer is the drive source in the system.Though noise is ubiquitous in environment, yet weigh with the standard that drives hot sound refrigerating machine, its sound pressure level is too little, cannot directly be used.In order to reach the purpose that turns waste into wealth, the problem of overriding concern is that sound pressure level is improved.In view of we do not add the prerequisite of the new useful energy, must realize so just can improving acoustic streaming density by mechanical mode focusing on the smaller area than larger area sound merit.Yet we will inevitably produce reflection when knowing on acoustic irradiation to a surface (especially rigid plane), are unfavorable for our collection sound merit like this.Iff being in order to overcome the reflection of merit, we can certainly adopt the sound-absorbing material with strong acoustically effective, but the sound wave that be absorbed into this moment but is consumed among the sound-absorbing material, thereby just are far from being and amplify and be used.So, we consider to adopt a kind of " ox horn type " sound passage (as shown in Figure 2) through particular design, in this sound channel, the sound wave of any direction incides arrival end (caliber is than butt end), its reflection channel must be that inwardly (end that the vial footpath is smaller) is unidirectional, so the sound merit on the tube inlet area will all focus on and carefully bring out mouth 8, sound merit density will improve greatly, and concrete multiplication factor only depends on both area ratios.It is a kind of simple but effective method that this structure is collected amplification to the sound merit, can realize the purpose that noise is used under the situation of not paying extra energy consumption.
Ambient noise through above-mentioned sound passage after, its sound pressure level has obtained improving greatly, is imported in the hot sound refrigerating machine then and goes, the outlet of sound passage is of coupled connections with the inlet of hot sound refrigerating machine, so successfully realize the alternative of hot sound refrigerating machine sound source.After sound wave entered in the resonatron of refrigeration machine, by parts such as hot end heat exchanger, heat sound plate superimposition cool end heat exchangers, realization thermoacoustic effect in heat sound plate is folded was to reach the purpose of refrigeration in succession.
