Description

Technical Field

[0001] This utility model belongs to the field of turbochargers, and in particular relates to a turbocharger with a high-efficiency intake and exhaust flow structure. Background Technology

[0002] A turbocharger is an intake booster device for internal combustion engines. It uses exhaust gases from the engine to drive a turbine, which in turn drives a coaxial compressor impeller to rotate at high speed. This compresses fresh air and forces it into the engine cylinders, increasing the amount of air entering the cylinders and thus improving the engine's power and torque. This device can significantly improve engine performance without significantly increasing engine displacement, while also helping to improve fuel economy and reduce emissions. It is widely used in the automotive, marine, and aerospace industries.

[0003] Chinese patent CN219412729U discloses a twin-scroll turbocharger, comprising a turbocharger body and a heat dissipation mechanism. The heat dissipation mechanism is installed on the shell wall of the turbocharger body and consists of a heat-conducting plate A, heat sink A, a heat-conducting plate B, and heat sink B. The outer wall of the turbocharger body is connected to the heat-conducting plate A by rivets, and several sets of heat sink A are welded to the wall of the heat-conducting plate A. Similarly, the outer wall of the turbocharger body is connected to the heat-conducting plate B by rivets, and several sets of heat sink B are welded to the wall of the heat-conducting plate B. This heat dissipation mechanism increases the heat dissipation of the turbocharger body, preventing excessively high turbocharger body temperature from reducing intake efficiency.

[0004] However, while the aforementioned twin-scroll turbocharger design improves heat dissipation and intake / exhaust efficiency through modifications to the cooling and flow channels, it suffers from a significant drawback: the lack of particulate matter filtration in the intake air. Without a dedicated filter, dust, sand, and other impurities enter the turbocharger along with the intake air. These particles can adhere to critical components such as the impeller and bearings, disrupting the impeller's dynamic balance, increasing bearing wear, and ultimately reducing the turbocharger's efficiency and lifespan. Therefore, designing a turbocharger with a highly efficient intake and exhaust flow structure is essential. Utility Model Content

[0005] This invention provides a turbocharger with a high-efficiency intake and exhaust flow structure, aiming to solve the problem that although the currently used dual-flow turbochargers have heat dissipation and flow channel optimization, they lack a filtration device, which easily allows dust and impurities to enter, damaging the impeller bearings and reducing performance and lifespan.

[0006] This invention is implemented as follows: a turbocharger with a high-efficiency intake and exhaust flow structure includes: a turbocharger body; an air intake device mounted on one side of the turbocharger body, the air intake device being used to assist in the input of air; an air filter device mounted on the air intake device, the air filter device being used to filter particles in the air; an anti-clogging device mounted on one side of the air intake device, the anti-clogging device being used to prevent particle blockage; a dual-function exhaust and exhaust assembly mounted on one side of the turbocharger body, the exhaust and exhaust assembly being used to assist in the exhaust of air; and a heat dissipation assembly mounted on the outer surface of the turbocharger body, the heat dissipation assembly being used to dissipate heat from the turbocharger body.

[0007] Preferably, the turbocharger body includes: an exhaust duct fixedly installed on one side of the turbocharger body, a control valve fixedly installed on the exhaust duct, and a cover plate fixedly installed at one end of the exhaust duct.

[0008] Preferably, the air filtration device includes: an inclined filter plate fixedly installed inside the exhaust duct, a discharge pipe fixedly installed on one side of the exhaust duct, and a dust collection bag fixedly installed at the bottom of the discharge pipe.

[0009] Preferably, the anti-clogging device includes: a connecting pipe fixedly installed on one side of the exhaust duct, and a fan fixedly installed on one side of the connecting pipe.

[0010] Preferably, the dual-function exhaust and ventilation component includes: an inlet and outlet air duct fixedly installed on the top side of one side of the turbocharger body, an inlet and outlet air duct mounting frame fixedly installed on one side of the inlet and outlet air duct, and an intake and exhaust fan fixedly installed on the intake and outlet air duct mounting frame.

[0011] Preferably, the heat dissipation assembly includes: an upper mounting ring fixedly installed on the top of the outer surface of the turbocharger body, a heat dissipation plate fixedly installed on the bottom of the outer surface of the turbocharger body, and a lower mounting ring fixedly installed between the upper mounting ring and the heat dissipation plate.

[0012] Preferably, multiple sets of lower mounting rings are provided, and the multiple sets of lower mounting rings are equidistantly arranged between the upper mounting ring and the heat sink.

[0013] Preferably, the feed pipe and the connecting pipe are located at the top of the inclined filter plate, and the feed pipe and the connecting pipe are arranged corresponding to each other.

[0014] Compared with related technologies, the turbocharger with a high-efficiency intake and exhaust flow structure provided by this utility model has the following beneficial effects:

[0015] When the turbocharger with its efficient intake and exhaust flow structure is operating, air is first introduced through the intake system. At this point, the inclined filter plate in the air filter system filters particulate matter from the air, preventing dust and impurities from entering the turbocharger body. The filtered impurities are collected in a dust bag through a discharge pipe to prevent clogging. Simultaneously, the fan in the anti-clogging device assists airflow through connecting pipes, further preventing clogging of the filter. The filtered clean air enters the turbocharger body, where the intake volume is regulated by the exhaust duct and control valve, while a cover plate provides protection. During the exhaust phase, the intake and exhaust fans in the dual-function exhaust and exhaust assembly assist in exhaust through the intake and exhaust ducts and the intake and exhaust mounting frame, improving exhaust efficiency. When increased airflow is required, the intake and exhaust fans switch to exhaust mode, introducing external air through the intake and exhaust ducts to increase the intake volume, thus meeting the needs of different operating conditions. The cooling system effectively dissipates heat from the turbocharger body. This design not only solves the problem of dust and impurities entering and damaging the impeller bearings and reducing performance life of the twin-scroll turbocharger due to the lack of a filtration device, but also further improves the overall performance and service life of the turbocharger by optimizing intake, exhaust and heat dissipation functions.
