Abstract

The invention relates to a warm air curtain formed by recycling engine exhaust heat and a manufacture method. The conduction oil is heated by the exhaust heat, the exhaust gas temperature is 400-600 DEG C, a conduction oil boiler is sleeved outside an exhaust pipeline, the conduction oil can cycle while the temperature is 350 DEG C, and no pressure is generated, an inflation drop tank is formed above the conduction oil boiler, the conduction oil boiler is provided with an input end and an output end at two ends, the exhaust gas passes through the middle of the conduction oil boiler and enters into an exhaust silencer after transferring the heat to the conduction oil boiler, the exhaust gas is guided to the fixed conduction oil boiler through a special exhaust high temperature snake-shaped pipe of the engine cylinder head exhaust manifold, the conduction oil boiler is provided with an electrical heated tube used for auxiliary heating while the large hot wind power is required and used for performing the insulation treatment, the heating conduction oil outputted by the conduction oil boiler is recycled to the conduction oil boiler after passing through a radiator, the radiator is provided with a multi-grade cooling fan, and the cold air absorbed by the fan is heated by the radiator for forming the warm air curtain.

Description

technical field [0001] The invention relates to a recovery engine exhaust heat utilization and production method, which belongs to the field of energy recycling, and specifically refers to a hot air curtain produced by recovering engine exhaust heat and a production method. Background technique [0002] The power output of the engine is equipped with diesel and gasoline engines. Diesel engine fuel is compression ignition, the compression ratio in the cylinder is large, and the residual pressure is also large when exhausting. The exhaust port of the cylinder head is about 800 ° C, while the gasoline engine burns mixed gas. , the compression ratio in the spark combustion-supporting cylinder is small, the residual pressure is also small when exhausting, and the exhaust temperature is about 700°C. The temperature of the fuel burned by diesel engines and gasoline engines is different under various working conditions, and the general working conditions are 80%-90 %, the exhaust te...
