The exhaust muffler and the tail gas energy recovery device of the conventional internal combustion engine do not meet the requirements on compactness and high efficiency, have various structures and high manufacturing cost and cannot be standard accessories, so that the exhaust heat loss and the infrared radiation of the internal combustion engine are high, the utilization of the rest heat stays in a research stage, and the total energy efficiency does not break through 50%. Recycling the exhaust energy of the internal combustion engine is an effective way to improve the total energy efficiency, reduce the oil consumption and reduce the infrared radiation energy. The device is provided with an electromechanical hybrid power device and a power device consisting of a hydrogen fuel cell and a power cell, waste heat energy of the recovery device is required to be used for heat preservation of the cell and the device in a low-temperature environment, high-efficiency low-emission engines such as homogeneous charge compression ignition and rotors need exhaust regenerative cycle and reduce fire loss in low-medium cycle and low-temperature environments, and external waste gas recirculation is required in high cycle to reduce combustion intensity and harmful substance emission; compared with the heat dissipation capacity of a cooling water tank of an internal combustion engine with the same capacity, the waste heat generated in the work of the proton exchange membrane fuel cell is multiplied, and the heat dissipation temperature difference is small, and in addition, an air conditioner condenser, an air inlet intercooler and a radiator of a power control unit special for the fuel cell bring a severe test to the heat dissipation layout of a front cabin of a fuel cell car, and even the heat dissipation requirement of the front cabin is met at the cost of sacrificing the power of a galvanic pile; the working temperature of the molten carbonate and solid oxide fuel cell is high, the discharge temperature is also high, and whether the discharged waste heat is utilized or not can influence the whole efficiency; the air filter, the supercharger and the intercooler of the air inlet system of the existing internal combustion engine and the fuel cell are independently arranged and connected through pipelines, so that the volume is large and not compact, and the air inlet resistance is large; an exhaust silencing heat exchange device of an engine, an electromechanical hybrid power device, a high-temperature exhaust heat utilization device and a cooling device of a fuel cell stack and an intake intercooling assembly integrated silencing heat exchange device all need a new heat exchange element with a silencing function. In addition, a heat regenerator and an air preheater which are efficient, compact and low-cost, integrated with a host machine and easy to automatically produce are needed for a micro gas turbine, an aviation turbine shaft, a turboprop engine and a hot air engine so as to improve the efficiency of the whole machine and reduce the exhaust temperature and noise; in addition, the gas water heater and the gas wall-mounted heating stove also have the problems of high exhaust temperature, high exhaust noise and the like, and the main reason is that the heat exchanger adopts a finned tube type, a tube belt type or a plate fin type and the like, and the traditional equipment is not easy to form a multi-flow variable-section heat exchange channel structure and does not have the silencing function; domestic gas cookers, domestic production enterprises mainly develop fuel combustion technologies of burner heads, the application and development of heat transfer, noise elimination and heat utilization technologies after combustion are few, and some commercial gas cookers have high combustion noise and low utilization efficiency of flue gas waste heat, and the flue gas waste heat of the domestic gas cookers is not recycled, so that the proportion of the domestic gas cooker products which can achieve 1-level energy efficiency in the market is less than 10%; the domestic fuel oil hot water (hot air) heater adopts flue gas to fold back the heating water jacket fins, and the flue gas is heated by the outer wall of the combustion cylinder in a radiation mode at the same time to form flue gas heat release and be heated, so that the problems of high exhaust gas temperature, high noise, low energy utilization rate, large environmental pollution and the like are caused; the condenser and the evaporator of the air conditioner are arranged in a split mode, so that the problems of more materials, large volume of the whole air conditioner and unsafe danger of mounting the condenser are caused, the micro-channel condenser sometimes has 'ice blockage' and cannot run, particularly, the air conditioner has no new air supplementary circulation, and in addition, the adsorption type refrigeration equipment which is suitable for being driven by waste heat of mobile internal combustion engines of automobiles, ships and the like is not applied, and the main reason is that the energy efficiency and the technology of an adsorption bed are low.

The thermoacoustic equipment and the energy power device are indispensable energy utilization equipment for human to utilize energy, the common characteristic of the thermoacoustic equipment and the energy power device is that energy is combusted and utilized, so that heat energy is converted into mechanical energy or electric energy, or the heat energy is directly used for human living demands, the energy utilization efficiency problem is involved in the process of converting the energy into the mechanical energy and the electric energy or utilizing the heat energy, noise pollution and thermal pollution to the environment are generated along with the conversion of the energy into the mechanical energy and the electric energy, and the aim of efficiently and environmentally-friendly utilization of the energy by human is achieved.

Detailed Description

Example 1:

embodiment 1 is a noise elimination heat exchange passage structure of a first working medium mainly composed of a corrugated cylinder. As shown in fig. 1 and 2, the corrugated container 1, the metal container 2, the first working medium inlet 3 and the first working medium outlet 4, the corrugated container 1 is a cylindrical body formed by bending and enclosing a corrugated metal band, and the extending direction of the corrugated groove is the same as the axial direction of the container, the metal container 2 is arranged in the container cavity of the corrugated container 1, the outer wall of the metal container is close to the internal tooth peak of the inner wall of the corrugated container 1, so that the inner corrugated container forms a single inner corrugated container channel with two open ends, the front and rear ends of the corrugated container 1 are respectively sealed (by plates), the partition 5 arranged in the metal container 2 divides the space in the sealed corrugated container 1 into a front chamber 6 and a rear chamber 7, the first working medium inlet 3 and the first working medium outlet 4 are arranged at the same end of the corrugated container or at different ends and are respectively communicated with the front chamber 6 and the rear chamber 7 (when the first working medium inlet 3 and the first working medium outlet 4 are arranged at the same end, the first working medium inlet 3, the front chamber 6, the inner corrugated groove channel, the rear chamber 7 and the first working medium outlet 4 form a silencing heat exchange passage of the first working medium which is communicated in sequence.

Embodiment 1 may be provided with an extension pipe 12 in the rear chamber 7, one end of the extension pipe 12 extends radially outward to be connected with the inner rim of the corrugated cylinder 1, the other end extends axially away from the end of the first working medium outlet 4, the extension pipe 12 is used for guiding and separating air flow and noise, and if the extension pipe is provided with an opening and forms a jacket type micro-perforated resonance sound absorption structure with a pipeline additionally arranged therein. The space inside the enclosed corrugated cylinder 1 includes the end of the corrugated cylinder 1.

The bending part of the corrugated cylinder close to the central shaft is an internal tooth peak, and the bending part far away from the central shaft is an external tooth peak; the internal tooth peaks of the corrugated cylinder are welded with the outer wall of the metal cylinder, and the outer side of the corrugated cylinder is surrounded with the inner wall of the other metal cylinder; two ports of the corrugated channel of the corrugated cylinder can be blocked by a fin belt 13 (a sealing belt, a section line part is marked in the figure), so that the inner corrugated channel port and the outer corrugated channel port at two ends are independent, and the corrugated channel port blocked by the fin belt 13 is opened on the side surface.

The noise airflow after the engine does work realizes the cooling and noise reduction process in the corrugated cylinder silencing passage structure: the exhaust of the engine (high-temperature and high-noise turbulent flow pulsating mixed gas) enters the front chamber from the first working medium inlet and expands, and the acoustic impedance in the channel suddenly changes due to the sudden expansion of the channel section formed by the first working medium inlet pipe and the front chamber, so that the exhaust noise with certain frequency is reflected and interfered at the position; when exhaust noise sound waves enter a wedge inlet of an inner corrugated groove channel at the front end of the corrugated cylinder (namely, a silencing wedge inlet formed between internal tooth peaks of the corrugated cylinder), the exhaust noise sound waves entering the inner corrugated groove channel from the wedge inlet are divided into a plurality of beams, each beam of small sound waves are repeatedly reflected in the inner corrugated groove channel and collide with the wall surface of the channel to consume energy, and meanwhile, temperature difference heat transfer exists between the exhaust and the wall surface of the channel, so that the energy consumed by collision of the exhaust noise and the exhaust heat energy are finally radiated through the outer wall surface of the corrugated groove channel in a heat energy mode, and the sound pressure is further reduced; meanwhile, when exhaust enters the inner corrugated channel from the front chamber and flows to the rear outlet along the inner corrugated channel, a part of exhaust noise returns to the front chamber because the difference between the wedge inlet direction of the inner corrugated channel and the flow direction of the corrugated channel is about 90 degrees; in the process of flowing of the exhaust entering a corrugated groove channel in the corrugated cylinder to an outlet at the rear end along the channel, because the inner corrugated groove channel can be a channel provided with a certain type of fin, or a corrugated channel, or a cross corrugated channel, or a support turbulence straight channel and other structures (the corrugated groove channel can be made into a zigzag shape along the axial direction), when the exhaust noise flows in the corrugated groove channel with small hydraulic diameter, on one hand, the exhaust exchanges heat with the corrugated groove channel, on the other hand, the exhaust noise repeatedly reflects and collides in the channel to consume energy, the consumed energy and the exhaust heat transfer energy are finally dissipated through the outer wall surface of the corrugated cylinder in the form of heat energy, and the exhaust noise and the reduction of temperature further reduce the sound pressure; finally, exhaust gas flows out from an outlet of the inner corrugated groove channel and returns 180 degrees through the extension pipe to enter a rear chamber, and part of exhaust noise returns to the corrugated groove channel; and the exhaust noise entering the rear chamber is further expanded and expanded, the sound pressure is further reduced, and finally the exhaust noise is reduced to the requirement in the corrugated cylinder silencing passage structure and then is discharged from the first working medium outlet pipe.

The axial section of the corrugated channel is rectangular, trapezoidal or parabolic, and the axial direction of the corrugated channel is a straight channel, or a straight channel with fins, or a zigzag corrugated channel, etc. On one hand, the total flow area of the corrugated groove channel is larger than the area of the first working medium outlet and inlet pipe, so that the channel resistance influence is small; on the other hand, the flow of the exhaust noise in the corrugated groove channel is a honeycomb type resistive noise elimination process, and because the reflection times of the sound wave in the corrugated groove channel are increased, and the contact chance of the surface area of the corrugated groove channel and the noise wave is also increased, the noise elimination effect is improved, and the medium-high frequency noise wave of the exhaust noise in the corrugated groove channel is better eliminated; meanwhile, heat converted from medium-high frequency noise waves of the exhaust gas and the exhaust gas heat are radiated through the outer wall surface of the corrugated groove channel, and the exhaust gas is cooled in each corrugated groove channel, so that the exhaust gas temperature is reduced, the sound pressure is reduced, and the sound intensity is reduced greatly.

The corrugated cylinder silencing passage structure is an impedance composite silencing structure formed by communicating an annular corrugated groove type resistive silencing channel with a front chamber and a rear chamber (resistant expansion), wherein the front chamber and the rear chamber have a better silencing effect on noise waves in a low-intermediate frequency range, the corrugated groove type resistive silencing channel has a better silencing effect on noise waves in a medium-intermediate frequency range, and the silencing frequency band of the impedance composite silencing structure is wide; a partition plate can be additionally arranged in the front chamber or the rear chamber with larger space to form silencing elements such as a resonant cavity, and the opening of the resonant cavity is communicated with the front chamber or the rear chamber, or communicated with the inlet or the outlet of the first working medium, or communicated with the inner corrugated groove channel; the baffle of the corrugated cylinder can be provided with an adjusting door with a silencing structure, or other silencing elements are arranged in the corrugated cylinder to further form various exhaust silencing structures.

The surface area of the external corrugated groove is more than ten times of that of the cylinder, when the external corrugated groove is used for an engine exhaust silencer, the heat transfer area to the external air is large, the temperature of engine exhaust in a corrugated cylinder silencing passage structure is reduced quickly, the reduction of the exhaust temperature reduces the noise wavelength, the transmission loss curve moves towards the low frequency direction, and the reduction of the exhaust temperature also reduces the propagation speed of sound waves in a medium, reduces the average flow velocity of exhaust, and reduces the exhaust flow resistance loss and the regeneration flow noise; in addition, the geometric center line of each inner corrugated groove channel is staggered with the axial line of a first working medium inlet and outlet pipe of the front and rear expansion chambers by the maximum axial distance and is increased along with the increase of the diameter of the corrugated cylinder, so that exhaust noise waves cannot pass through the expansion chambers in a narrow beam form, the upper limit cutoff frequency is not reduced due to expansion, the upper limit failure frequency is improved due to the fact that the channel is divided into a plurality of corrugated groove channels, the noise elimination frequency is wider, the medium-high frequency noise elimination effect is better, and the noise elimination amount mainly depends on the diameter of the corrugated cylinder and the length of the inner corrugated groove channels.

The silencing and heat exchange passage structure has the advantages that through the communication of the front chamber and the rear chamber with different geometric characteristics and acoustic characteristics by the corrugated groove channel which is encircled into a ring, the sound pressure of exhaust noise with different frequencies is reduced, the direction of exhaust noise airflow is changed for many times, and an exhaust airflow field is separated from a noise field; passing the exhaust flow through the expanding or contracting section a plurality of times to smooth the exhaust flow pulsation pressure wave and the volume flow pulsation; particularly, the exhaust flow channels are uniformly dispersed to all corrugated groove channels, so that the noise elimination frequency range is improved, the heat of exhaust flow and the heat converted by noise are all transmitted to the inner wall of the corrugated groove channels, then the heat is dissipated by the outer wall surface of the corrugated groove, and the energy, the flow speed and the volume flow of the exhaust flow are all reduced after the high-temperature exhaust gas is cooled; the structure meets the exhaust noise elimination principle, creates conditions for energy recycling of high-temperature exhaust noise, and the heat exchange quantity is related to the width (hydraulic diameter) and the number of corrugated groove channels and the structural form.

Example 2:

in embodiment 2, a noise reduction heat exchange path structure mainly composed of inner and outer corrugated grooves of a corrugated cylinder is used. As shown in fig. 3, based on embodiment 1, further, a metal cylinder 2 is sleeved outside the corrugated cylinder 1, and a second working medium inlet 8 and a second working medium outlet 9 are provided, an outer crest of the outer wall of the corrugated cylinder 1 abuts against an inner wall of the metal cylinder 2, so that the corrugated grooves on the outer side form independent outer corrugated groove channels with two open ends, and a noise elimination heat exchange structure for heat transfer and temperature reduction of the corrugated cylinder is formed between the outer corrugated groove channels and the inner corrugated groove channels, the two open ends of each outer corrugated groove channel are respectively collected and respectively communicated with the second working medium inlet 8 and the second working medium outlet 9 to form a noise elimination heat exchange passage of the second working medium of the corrugated cylinder 1, the noise elimination heat exchange passage of the second working medium of the corrugated cylinder 1 and the noise elimination heat exchange passage of the first working medium of the corrugated cylinder 1 form a noise elimination heat exchange passage of the corrugated cylinder 1, and fins may be provided in the corrugated groove channels.

The extension pipe and the pipeline additionally arranged in the extension pipe can form a heat-absorbing jacket sleeve at a certain distance to be connected with the first working medium outlet. The embodiment is used for silencing exhaust gas of an engine and recovering waste heat, the inner metal cylinder can also be a heat storage jacket pipe, so that the temperature of the recovered heat is stable, the inner metal cylinder can be used for high-grade application such as regenerative cycle of an internal combustion engine, and the inner metal cylinder can also be used for heat preservation of a power battery of a hybrid power device, heating and other applications.

The corrugated groove channel is long and narrow in radial direction, and the radial curvature can be changed through bending, so that the mechanical strength and compactness of the noise-elimination heat exchange structure are further improved, and thermal stress is released. If the silencing heat exchange passage structure is used for a 'regenerator' of a micro-combustion engine, the silencing heat exchange passage structure is a high-compactness silencing heat exchange passage structure which requires higher mechanical strength and smaller volume, and simultaneously works under a high-temperature environment with large thermal stress.
