BIDIRECTIONAL SWIRL MIXING DEVICE FOR AIR SOURCE SYSTEM HEAT EXCHANGER

Title:

BIDIRECTIONAL SWIRL MIXING DEVICE FOR AIR SOURCE SYSTEM HEAT EXCHANGER

Document Type and Number:

WIPO Patent Application WO/2023/103809

Kind Code:

A1

Abstract:

A bidirectional swirl mixing device for an air source system heat exchanger of an aircraft, comprising an outer sleeve (20) and an inner sleeve (40). The inner sleeve (40) is arranged within the outer sleeve (20) and the two sleeves are spaced apart from each other. The mixing device further comprises: multiple outer ring stator blades (30) which are spaced apart and fixedly connected to the inner wall surface of the outer sleeve (20) and the outer wall surface of the inner sleeve (40); and multiple inner ring stator blades (50), which are spaced apart and fixedly connected to the inner wall surface of the inner sleeve (40). The outer ring stator blades (30) and the inner ring stator blades (50) are arranged at different angles relative to the longitudinal axis of the inner sleeve (40). When the outer ring blades and the inner ring blades incline in opposite directions relative to the longitudinal direction, the bidirectional swirl mixing device can enable airflow passing through the inner ring blades and the outer ring blades to rotate in opposite directions, so that the two strands of airflow are wound and mixed, and the temperature field is quickly and efficiently homogenized.
