Abstract

The invention discloses a management method of micro scale composite phase change cooling automobile and a device thereof, and relates to the engine technology. The method utilizes the characteristic that the composite phase change heat exchange of the evaporation and boiling of working medium in a micro channel has extremely high heat exchange strength, thus improving the heat exchange efficiency greatly; the management device consists of a heat absorption and conversion device, an air-cooled type condenser, an electromagnetic valve, a liquid backflow pipe and a steam insulating pipe; the liquid inlet of the heat absorption and conversion device is connected with the liquid outlet of the air-cooled type condenser by the liquid backflow pipe; the steam outlet of the heat absorption and conversion device is connected with the steam inlet of the air-cooled type condenser by the steam insulating pipe; and the electromagnetic valve is arranged on the liquid backflow pipe and the management device is vacuumized. The management method and the device of the invention reduce the over-high temperature of the tail gas of the automobile effectively, lead a three-way catalytic device of the automobile to work normally and reduce the content of pollutants in the tail gas of the automobile effectively.

Description

Technical field: [0001] The invention relates to the technical field of engines, and is an efficient gas cooling method and device. The temperature of high-temperature gas can be significantly reduced after being cooled by the device. It is suitable for the cooling of high-temperature exhaust gas of high-power engines, so that the exhaust gas of automobiles can meet the increasingly strict emission standards of automobile exhaust gases. technical background: [0002] From the beginning of the 19th century to the present two hundred years, the automobile industry has developed rapidly. So far, the number of automobiles in the world has exceeded 800 million. As the most important means of transportation, automobiles have become a symbol of modern social civilization. However, while automobiles are vigorously promoting the development of productivity and providing great convenience for people to travel, the tail gas emitted by them is also harmful to human health and has cause...
