Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0033] Referring to Figure 1 , Figure 3 , Figure 4 An embodiment provided by the utility model: an anti-explosion turbocharger 3, comprising an air valve 1, the air valve 1 can accurately control the exhaust gas of engine emission to enter, ensure that the gas flow and pressure of subsequent device are stable, provide suitable intake condition for the efficient operation of subsequent structure. The outside of air valve 1 is detachably connected with butt frame 2 by screw, so as to facilitate the rapid replacement of parts when equipment maintenance or fault repair. The other end of butt frame 2 is fixedly connected with turbocharger 3, turbocharger 3 utilizes the exhaust gas energy of engine to drive the high-speed rotation of turbine, and then drives the high-speed rotation of coaxial compressor impeller, sends the compressed air into the engine cylinder, and increases the air intake of engine. The output end of turbocharger 3 is fixedly connected with sealing mechanism, the other end of sealing mechanism is detachably connected with heat dissipation mechanism, the other end of heat dissipation mechanism is fixedly connected with booster pump 19, and booster pump 19 further improves the pressure of gas.
[0034] The sealing mechanism includes a connecting pipe 4, one end of the connecting pipe 4 is fixedly connected to the output end of the turbocharger 3, the connecting pipe 4 is used to ensure smooth and stable transmission of the gas, avoid gas leakage or pressure loss caused by poor connection. The inner wall of the connecting pipe 4 is fixedly connected with a plurality of rubber rings 5, when the gas flows in the connecting pipe 4, the rubber ring 5 can tightly fit between the inner wall of the pipeline and the component transmitting the gas, forming an effective seal to prevent gas leakage from the gap between the pipe wall and the component. The other end of the connecting pipe 4 is provided with a plurality of connecting holes 6, the connecting holes 6 are used for precise connection with the subsequent components, to ensure the tightness and stability of the connection. The outer wall of the connecting pipe 4 is fixedly connected with a filling ring 12, the filling ring 12 has a certain deformation ability, the outer wall of the filling ring 12 is slidingly connected with an extrusion shell 11, when the extrusion shell 11 is subjected to external force, it will extrude the filling ring 12, causing it to deform, and the filling ring 12 will tightly fit between the extrusion shell 11 and the connecting pipe 4, further enhancing the sealing of the connection, effectively preventing gas leakage from the connecting part of the connecting pipe 4 and the extrusion shell 11.
[0035] The top of the filling ring 12 is slidingly connected with two tight shells 7, one end of the extrusion shell 11 is in contact with the outer wall of the tight shell 7, and the outer wall of the tight shell 7 is in contact with one end of the outer wall of the connecting pipe 4, when the extrusion shell 11 is displaced, it will push the tight shell 7 to move, so that it tightly fits with the outer wall of the connecting pipe 4, thereby forming a multiple sealing structure. The inner wall of the tight shell 7 is fixedly connected with a plurality of springs 8, the other end of the spring 8 is fixedly connected with a push block 9, the spring 8 can automatically stretch and contract according to different degrees of stress changes of the sealing structure, and tightly press the sealing ring 10 on the corresponding contact surface through the push block 9, always maintaining good sealing effect. When the pressure increases, the sealing ring 10 is compressed, and the spring 8 is compressed; when the pressure decreases, the spring 8 rebounds, so that the sealing ring 10 can still maintain sufficient sealing pressure.

[0037] Referring to Figures 1 to 2The heat dissipation mechanism includes a intercooler shell 13, the outer wall of the intercooler shell 13 is detachably arranged at the other end of the butt joint pipe 4, and the intercooler shell 13 provides a stable installation and working environment for the internal heat dissipation components. The bottom inner wall of the intercooler shell 13 is fixedly connected with a liquid storage tank 14, the liquid storage tank 14 is used for storing cooling liquid, ensuring that the heat dissipation process will not be interrupted due to insufficient cooling liquid, and maintaining the stability and reliability of the heat dissipation system. The top of the liquid storage tank 14 is provided with a controller 15, which can accurately monitor and control the temperature, liquid level and circulation speed of the cooling liquid in the liquid storage tank 14. The inside of the liquid storage tank 14 is fixedly connected with a plurality of circulating pipes 16, which ensure that the cooling liquid can be uniformly and efficiently distributed to each heat dissipation part, increase the contact area of the cooling liquid with the outside, and improve the heat exchange efficiency. The outer side of the circulating pipe 16 is provided with a plurality of grooves, which not only increase the surface area of the circulating pipe 16, so that the cooling liquid can flow in the pipe and exchange heat with the outside environment more fully, but also can disturb the flow state of the cooling liquid to some extent, enhance the turbulence degree, and further improve the heat transfer efficiency.
[0038] The inner wall of the intercooler shell 13 is fixedly connected with a plurality of heat dissipation fins 17, the shape of the heat dissipation fins 17 is triangular wave shape, the inner and outer walls of the plurality of circulating pipes 16 are in contact with the outer walls of the plurality of heat dissipation fins 17, the triangular wave shape increases the surface area of the heat dissipation fins 17, compared with the traditional plane fins, the triangular wave shape of the heat dissipation fins 17 can contact the surrounding air more fully, thereby improving the heat exchange efficiency between the air and the heat dissipation fins 17. When the hot cooling liquid flows in the circulating pipe 16, the heat is quickly transferred to the heat dissipation fins 17, the heat dissipation fins 17 dissipate heat to the surrounding air through a large area of surface, due to its special shape, the air forms turbulence when flowing through the heat dissipation fins 17, enhances the convective heat transfer effect of the air, accelerates the heat dissipation, and further improves the heat dissipation capacity of the heat dissipation mechanism. The outside of the intercooler shell 13 is provided with a fan 18, the fan 18 generates forced convection airflow by rotating, accelerates the flow speed of the air around the intercooler shell 13. The turbocharger 3, the intercooler shell 13, the booster pump 19 and the air exchange valve 1 are connected through a communication pipe 20, the communication pipe 20 plays the role of flow channel for gas transmission between components, and the two ends of the communication pipe 20 are fixedly connected with sealing interfaces 21, thereby enhancing the sealing performance of the connection parts between the communication pipe 20 and the components, and effectively preventing gas leakage.
[0039] Working principle: when turbocharger 3 works, gas enters the butt joint pipe 4 from the output end, the flow of gas drives the rubber ring 5 in the butt joint pipe 4 to closely adhere to the pipe wall and the transmission part, preventing the pipe wall gap from leaking, and the butt joint hole 6 on the butt joint pipe 4 is prepared for the connection of the subsequent components. And when the external force generated by the turbocharger works on the extrusion shell 11, the extrusion shell 11 slides along the outer wall of the filling ring 12, and the extrusion makes the filling ring 12 deform and closely adhere to the extrusion shell 11 and the butt joint pipe 4, enhancing the sealing of the connection. The displacement of the extrusion shell 11 pushes the tight shell 7 to slide on the top of the filling ring 12, so that it closely adheres to the outer wall of the butt joint pipe 4 to form a multiple sealing structure. And due to the temperature of the gas, the stress change caused by the vibration of the turbocharger work drives the spring 8 in the tight shell 7 to automatically expand and contract, and the expansion and contraction of the spring 8 drives the push block 9 to slide in the tight shell 7, and the push block 9 tightly presses the sealing ring 10 on the outer wall of the butt joint pipe 4 and the sealing shell, and the sealing ring 10 can deform with the slight displacement or deformation of the components, thereby effectively preventing gas leakage, ensuring the efficient sealing of the output port of the turbocharger 3, and ensuring the stable operation of the whole system, so that the gas is stably transmitted to the subsequent mechanism.
[0040] When the turbocharger 3 works and generates heat, the high-temperature gas flows through the intercooler through the communication pipe 20, and the coolant stored in the liquid tank 14 is accurately controlled by the controller 15, and according to the changes of the temperature, liquid level and circulation speed of the coolant, etc. Parameters change through the circulation pipe 16 to circulate, and the grooves on the circulation pipe 16 increase the surface area and disturb the flow state of the coolant, so that the coolant can exchange heat with the outside more efficiently, and then the heat is transferred to the triangular wave-shaped heat dissipation fins 17 in contact with it. The heat dissipation fins 17 increase the contact area with the air due to their special shape, and the heat transfer forms a turbulent flow when the air flows through, enhancing the convective heat transfer effect and driving the heat to dissipate into the air. At the same time, the fan 18 outside the intercooler shell 13 rotates to generate forced air flow, which drives the air around the intercooler shell 13 to flow faster, further enhancing heat dissipation.
[0041] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the foregoing embodiments, or to make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
