Heat exchange silencer

Abstract

The invention relates to a heat exchange silencer. Advanced silencing principles such as micropore jet partition, counter-phase and split-gas rushing and a thermoacoustic effect, a composite silencing theory and a strengthened heat transfer technology are adopted, 8 layers of round tubes with different lengths and diameters are sleeved on one axis to form a centrifugal S-shaped heat release silencing channel in which diesel exhaust flows from the center to the outside, and a centripetal S-shaped heat absorption channel in which a heat absorption medium flows from an outer layer to an inner layer through guide pipes and baffles, a structure flow channel for gradually reducing the temperature of noise air flow by mixing air flow at different temperatures and with counter-phase noise wave for multiple times is highlighted, and excess heat, excess pressure energy and noise energy are recovered from internal combustion engine exhaust through cold and hot working medium inlets and outlets formed at the two ends.

Description

Technical field: [0001] The invention is a heat exchanging muffler which combines heat exchanging function and muffler performance and simultaneously performs heat exchanging and muffler, and relates to thermal engineering, fluid mechanics and acoustics. Background technique: [0002] Diesel engine, one of the types of internal combustion engines, has been widely used in various ships, diesel locomotives, highways, etc. Commercial transportation, power generation, geological oil exploration and drilling, agricultural machinery power, construction machinery and military vehicles and equipment, etc. In my country, the heat equivalent converted into effective work by diesel engines accounts for 30% to 45% of the calorific value of fuel combustion, and 90% of the remaining 55% to 70% of the energy is lost through the cooling water of the diesel engine and the exhaust heat of high-temperature exhaust gas. Cooling water waste heat has been widely used in vehicle heating and some ...
