Abstract

The invention provides a heat exchange device of an air inlet and outlet pipe system and belongs to the technical field of mechanical design. The heat exchange device of the air inlet and outlet pipe system comprises an air inlet pipe, an engine, an air outlet pipe, an air compressor, a turbine, connecting pipes, a volume cavity, a moving body and a spring. The moving body is installed in the volume cavity and contacted with the inner wall surface of the volume cavity in sealing mode, a penetrating pipe penetrates through the upper wall surface and the lower wall surface of the moving body, and two ends of the spring are respectively connected with a left wall surface of the moving body and the left wall surface of the volume cavity. When the engine is at a low-speed working condition, the moving body moves rightward in the volume cavity, a second connecting pipe is communicated with a fifth connecting pipe, outlet air waste heat is used for heating inlet air, cold starting performance of the engine is good; and when the engine is at a high-speed working condition, the moving body moves leftward in the volume body, and the second connecting pipe is separated from the fifth connecting pipe. The heat exchange device of the air inlet and outlet pipe system is reasonable in design, simple in structure and suitable for an engine inlet air heating system with a turbocharger.

Description

technical field [0001] The invention relates to an intake and exhaust system in the technical field of mechanical design, in particular to an intake and exhaust pipe system heat exchange device with a turbocharger. Background technique [0002] Harmful emissions from engines are a major source of air pollution. With the increasing importance of environmental protection, the goal of reducing harmful emissions from engines has become an important direction for engine development in the world today. With the world's consumption of petroleum products increasing year by year, the international oil price remains high, and the economy of the engine is becoming more and more prominent. Therefore, it is the primary task of engine designers to carry out research on the control methods of engine harmful emissions. By heating the intake system of the engine, it can not only improve the cold start performance of the engine under harsh conditions, but also reduce the exhaust pollution of...
