Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, in particular to a modular turbocharger volute structure. Background Art

[0002] A turbocharger is a device used to increase the intake air volume of an internal combustion engine. It mainly uses the energy of the exhaust gas discharged from the engine to drive a turbine, and the turbine drives the coaxial compressor impeller to rotate. The compressor impeller compresses the air and sends it into the intake manifold of the engine, increasing the air density entering the engine cylinder. With the continuous development of technology, modular turbochargers are gradually widely used.

[0003] A modular turbocharger is a supercharger structure in which each functional component of the turbocharger is designed as a relatively independent module and then combined together through specific interfaces. These modules mainly include a turbine module, a compressor module, an intermediate body module, and a wastegate module. Each module can be used as an independent unit during the design, manufacturing, and testing processes, facilitating production management and quality control. Among them, the modular turbocharger volute structure is an essential structure.

[0004] The modular turbocharger volute structure refers to a structural form in which the volute of the turbocharger is designed to be composed of multiple modules with specific functions and interfaces. Its main functions include guiding the flow of exhaust gas, being an energy conversion medium, protecting internal components, having a pressure regulation function, and improving the overall performance and efficiency. However, under the frequent action of high and low temperature cycles, the volute will have a thermal fatigue phenomenon, resulting in a decrease in material properties and even cracks. Especially under working conditions such as frequent start-stop, rapid acceleration, and rapid deceleration of the engine, the thermal fatigue problem will be more prominent. In the prior art, a cooling cavity with an air circulation pipe group is arranged on the volute, and the cooling cavity is connected to the inner cavity of the guide shell, and the exhaust gas self-circulation is used to cool the volute, effectively reducing the surface temperature of the volute and reducing the risk of thermal fatigue failure. However, the maintenance and management of the cooling device are also more complex. When the cooling device fails, it cannot be quickly repaired, which will affect the performance and reliability of the entire supercharger. Summary of the Utility Model

The mounting plate restricts the position of the hydrogel block to prevent excessive rebound. The above process ensures that the device can quickly dissipate heat when it overheats, extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

Clamping blocks 11 are installed at both the left and right ends of the front side of the second volute 10. A right-angle rod 16 is fixedly connected to the front side of the clamping block 11. An installation ball 17 is installed at the bottom of the right-angle rod 16. Through the installation of the right-angle rod 16, unnecessary rotation of the device is avoided.

A slot plate 18 is fixedly connected to the left side of the right installation circular plate 6. Through the installation of the clamping plate 7 and the slot plate 18, the device can be disassembled and installed. A heat dissipation mechanism 2 is installed on the right side of the first volute 1. The heat dissipation mechanism 2 is used for dissipating heat from the first volute 1. An installation ring 8 is installed on the top of the second volute 10. A plurality of first screws 9 are equidistantly threadedly connected to the top of the installation ring 8. Through the installation of the installation ring 8, the device is installed more stably. A second handle 20 is fixedly connected to the front side of the installation circular plate 6. A protective sleeve 13 is installed on the outer side of the second handle 20. Through the installation of the protective sleeve 13, the hand is prevented from slipping off when rotating the second handle 20;

[0033] Refer to Figure 1 、 Figure 2 and Figure 5, the heat dissipation mechanism 2 includes a fan 201. The fan 201 is installed in the middle of the right side of the first volute 1. A fixed block 204 is fixedly connected to the front end of the right side of the first volute 1. A spring 206 is fixedly connected to the bottom of the fixed block 204. Through the installation of the spring 206, the device can be rebounded. An installation plate 203 is arranged at the bottom of the fixed block 204. A hydrogel block 207 is fixedly connected to the bottom of the spring 206. An iron sheet 202 is fixedly connected to the bottom of the installation plate 203. Through the installation of the iron sheet 202, a sound can be emitted when the hydrogel block 207 rises. A button 205 is arranged at the bottom of the installation plate 203. A protection box 4 is installed outside the fan 201. A first handle 5 is fixedly connected to the middle of the right side of the protection box 4. Through the installation of the protection box 4, this mechanism is protected from damage. A sealing ring 15 is installed on the front side of the first volute 1. Second screws 14 are equidistantly threadedly connected to the front side of the sealing ring 15. Through the installation of the sealing ring 15, the first volute 1 is installed more firmly. The model of the fan 201 is Y4-73;

[0034] Refer to Figure 1 , Figure 2 and Figure 3 , a fixing plate 23 is installed in the middle of the top end of the connecting pipe 3. Installation round holes 19 are opened at both the front and rear ends of the fixing plate 23. Through the installation of the installation round holes 19, it is convenient to connect this device with other devices. A plurality of threaded pipes 22 are equidistantly fixedly connected to the right side of the second volute 10. Bolts 21 are threadedly connected inside the threaded pipes 22. Through the connection of the bolts 21, this device is installed more firmly;

[0035] Working principle: When the device needs to be overhauled, first remove the installation ball 17, then bend the right-angle rod 16 to other angles, and then rotate the second handle 20 protected by the protective sleeve 13, and rotate its two parts in opposite directions respectively, so that the rotating column 12 rotates accordingly, and then the clamping plate 7 is separated from the clamping groove plate 18, and the separation of the second volute 10 can be realized. When it needs to be assembled, rotate the two second handles 20 in the reverse direction, so that the rotating column 12 rotates back to its original position, so that the clamping plate 7 is re-engaged with the clamping groove plate 18, and the right-angle rod 16 is passed through the rotating column 12 again, and finally the installation ball 17 is installed in place, avoiding unnecessary rotation of the rotating column 12. And the same mechanism is installed on the front side of the second volute 10 for the above processes. The two work together to further strengthen the fixing effect. Through the above processes, the disassembly of the second volute 10 can be realized, which is convenient for overhauling its interior;

[0036] Since heat is dissipated when the device is working, when the heat dissipation is not timely, the internal temperature rises, causing the hydrogel block 207 to become smaller and lighter. Then, through the rebound of the spring 206, the position of the hydrogel block 207 rapidly rises, and then the button 205 can be pressed. At this time, the fan 201 is turned on, which can assist in heat dissipation. At the same time, it hits the iron sheet 202 and makes a sound. Through the installation of the mounting plate 203, the position of the hydrogel block 207 is restricted to prevent excessive rebound. Through the above process, when the internal temperature is too high, rapid heat dissipation can be achieved, and its service life can be extended.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
