[0021] As shown in Figure 4 And Figure 5 As shown in another embodiment of the utility model, the movable slot 4 is movably installed with the fixed rod 6 in the inside middle, the fixed rod 6 is movably installed in the inside of rotating rod 5, a plurality of shunt holes 10 are arranged through between guide slot 8 and first connecting slot 9, the second connecting slot 11 is movably installed with the second heat conduction sheet 15 in the inside of air outlet pipe 3, the second heat conduction sheet 15 is connected with the second buffer block 16, a plurality of annular turbulence sheets 17 are movably installed in the inside upper and lower ends of first connecting slot 9, and the annular turbulence sheets 17 are staggered and parallel to each other, a plurality of spiral heat dissipation sheets 14 are movably installed in the inside upper and lower ends of second connecting slot 11, and the first heat conduction sheet 13 is movably installed between the spiral heat dissipation sheet 14 and the first buffer block 12.

[0022] The gas enters the inside of the movable groove 4 along the gas inlet pipe 2, and then the gas in the inside of the movable groove 4 blows the blocking sheet 7, so that the blocking sheet 7 drives the rotating rod 5 to rotate around the fixed rod 6, thereby converting part of the kinetic energy of the gas into mechanical energy of the blocking sheet 7, thereby realizing the preliminary reduction of the kinetic energy of the gas, effectively reducing the direct impact force of the gas, and then the airflow is orderly guided into the inside of the guide groove 8, and then the gas in the inside of the guide groove 8 is accurately divided into multiple streams through a plurality of shunt holes 10, so that the airflow flows to the first connecting groove 9 at a lower flow rate and a more uniform distribution, so that the gas is more uniformly contacted with the second buffer block 16, so as to effectively convert the impact force of the airflow into heat energy through the second buffer block 16, and absorb and dissipate, thereby realizing the effective conversion and sound insulation of the airflow impact force, and then the gas flows along the second buffer block 16 to the annular spoiler 17, so that the gas is hindered and disturbed by the annular spoiler 17, forming complex vortex and turbulent flow, further consuming the kinetic energy of the airflow, reducing the noise level, and also making the airflow more uniformly distributed in the muffler, and finally the airflow after multiple conversion and noise reduction treatment is in contact with the first buffer block 12 again for secondary conversion and noise reduction. At this time, most of the kinetic energy in the airflow has been effectively reduced, and the noise has been greatly controlled. Finally, the airflow flows outward along the spiral heat sink 14 designed with care. The spiral heat sink 14 not only greatly increases the contact area of the airflow with the spiral heat sink 14, but also fully utilizes the flow of the airflow to take away the heat generated by the conversion. Finally, when the airflow flows outward along the rotating rod 5, it also takes away the temperature in the second heat-conducting sheet 15, realizing efficient heat dissipation.

[0023] The first buffer block 12 and the second buffer block 16 are made of mineral wool and glass fiber. Mineral wool and glass fiber are both excellent sound-absorbing materials. Mineral wool is known for its fibrous structure and good sound-absorbing and sound-insulating performance, and can effectively convert sound energy into heat energy, reduce sound reflection and propagation. Glass fiber performs well in absorbing high-frequency noise and can suppress vibration and reflection to achieve better sound insulation effect. The combination of the two can integrate the sound-absorbing properties of both and achieve wider-band noise elimination, improving the overall sound-absorbing performance of the muffler.

[0024] The first heat-conducting sheet 13 is used to conduct heat from the first buffer block 12 to the spiral heat sink 14, and the second heat-conducting sheet 15 is used to conduct heat from the inside of the second buffer block 16, thereby facilitating the airflow to take away the temperature in the spiral heat sink 14 and the second heat-conducting sheet 15 during the flow process, realizing heat dissipation

[0025] The working principle of the muffler with airflow circulation and heat dissipation is as follows:

[0026] In use, firstly, the gas enters the interior of the movable groove 4 along the gas inlet pipe 2, and then the gas in the interior of the movable groove 4 blows the blocking sheet 7, so that the blocking sheet 7 drives the rotating rod 5 to rotate around the fixed rod 6 as the axis, thereby converting part of kinetic energy of the gas into mechanical energy of the blocking sheet 7, so as to realize preliminary reduction of kinetic energy of the gas, effectively reducing the direct impact force of the gas, and then the airflow is orderly guided into the interior of the guide groove 8, and then the gas in the interior of the guide groove 8 is accurately divided into multiple thin streams through the plurality of shunt holes 10, so that the airflow flows to the first connecting groove 9 at a lower flow rate and a more uniform distribution, so that the gas is more uniformly contacted with the second buffer block 16, so as to effectively convert the impact force of the airflow into heat energy through the second buffer block 16, and absorb and dissipate, so as to realize effective conversion and sound insulation of the impact force of the airflow, and then the gaseous state flows along the second buffer block 16 to the annular spoiler 17, so that the gas is hindered and disturbed by the annular spoiler 17, forming complex vortex and turbulent flow, further consuming kinetic energy of the airflow and reducing noise level, and also making the airflow more uniformly distributed in the muffler, and finally the airflow subjected to multiple conversion and noise reduction processes contacts the first buffer block 12 again for secondary conversion and noise reduction, at this time, most of the kinetic energy in the airflow has been effectively reduced, and the noise has been greatly controlled, and finally the airflow flows outward along the spiral heat sink 14 designed with care. The spiral heat sink 14 not only greatly increases the contact area of the airflow with the spiral heat sink 14, but also fully utilizes the flow of the airflow to take away the heat generated by the conversion, and finally when the airflow flows outward along the rotating rod 5, the temperature in the interior of the second heat-conducting sheet 15 is also taken away, realizing high-efficiency heat dissipation.
