The invention discloses a bidirectional rotational flow mixing device for a heat exchanger of an aircraft air source system, the mixing device comprises an outer sleeve and an inner sleeve, the inner sleeve is located in the outer sleeve, and the two sleeves are spaced from each other; the mixing device further comprises a plurality of outer ring stator blades, and the outer ring stator blades are fixedly connected with the inner wall face of the outer sleeve and the outer wall face of the inner sleeve at intervals. The plurality of inner ring stator blades are fixedly connected with the inner wall surface of the inner sleeve in a mutually separated manner; the outer ring stator blades and the inner ring stator blades are arranged at different angles relative to the longitudinal axis of the inner sleeve. When the outer-ring blades and the inner-ring blades incline in opposite directions relative to the longitudinal direction, the two-way rotational flow mixing device can enable air flows passing through the inner-ring blades and the outer-ring blades to rotate in opposite directions, so that the two air flows are wound and mixed with each other, and the purpose of quickly and efficiently realizing temperature field homogenization is achieved.

    本发明公开一种用于飞机气源系统换热器的双向旋流混合装置,该混合装置包括外套筒和内套筒,其中内套筒位于外套筒之内,并且两个套筒相互间隔开;混合装置还包括多个外圈定子叶片,多个外圈定子叶片彼此隔开地固定地连接所述外套筒的内壁面和所述内套筒的外壁面;以及多个内圈定子叶片,多个内圈定子叶片彼此隔开地固定地连接所述内套筒的内壁面;外圈定子叶片和内圈定子叶片相对于内套筒的纵向轴线以不同的角度布置。当外圈叶片和内圈叶片相对于纵向方向以相反的方向倾斜时,双向旋流混合装置能使经过内外两圈叶片的气流够产生相反方向的旋转,从而使两股气流相互缠绕混合,达到快速且高效地实现温度场均匀化的目的。
