A Fan Exhaust Induced Ram Air Environmental Control Liquid Cooling Integrated System

Abstract

The invention belongs to the technical field of aircraft environment control systems and relates to a fan exhaust induced, ram-air and environmental control liquid cooling integrated system. The fan exhaust induced, ram-air and environmental control liquid cooling integrated system comprises an air cycle refrigeration system (1) and a liquid cooling system; the liquid cooling system comprises an air-liquid heat exchanger (2); the air cycle refrigeration system (1) comprises an air-air heat exchanger (3); after pumping outside air through theair-liquid heat exchanger (2), the air cycle refrigeration system (1) exhausts the air through an ejector (4) which is communication with a fan exhaust passage of the air cycle refrigeration system (1); and the ejector (4) is in communication with an air inlet passage passing through the air-air heat exchanger (3). The invention provides the fan exhaust induced, ram-air and environmental control liquid cooling integrated system which realizes refrigerating capacity by using small flow.

Description

technical field [0001] The invention belongs to the technical field of aircraft environmental control systems, and relates to a fan exhaust induced ram air environmental control liquid cooling integrated system. Background technique [0002] If the aircraft only uses the external air ram head to provide power for the radiator group during flight, it is likely that the ram air cannot flow through the radiator group due to the excessive flow resistance of the cold side of the radiator group, so the simple refrigeration components usually used The fan end draws ram air to provide cooling air for the air-liquid heat exchanger / air-air heat exchanger group, but because the liquid cooling system provides a large enough cooling capacity for the task system, the flow resistance of the cold side of the radiator is very high Usually, there are two problems that the fan pressure rise cannot make the ram air cooler pass through the radiator group and the load on the fan end of the compon...
