The invention relates to a rotational flow mixing device for a heat exchanger of an aircraft air source system. The cyclone mixing device comprises a sleeve, wherein the sleeve comprises a front end attached to the airflow system precooler and a rear end attached to a downstream pipeline; wherein the rotational flow mixing device comprises a plurality of stator blades, the stator blades are fixedly arranged on the inner circumferential wall of the sleeve, the adjacent stator blades are separated from each other along the inner circumferential surface of the sleeve, each stator blade is provided with a windward side relative to the airflow direction, and the windward side forms an inclined included angle relative to the airflow direction. According to the rotational flow mixing device, mixing of a non-uniform temperature field is accelerated at an outlet sealing head of the heat exchanger, the temperature control problem caused by the non-uniform temperature field is effectively solved, the flow resistance of the optimized rotational flow structure is small, and the influence on performance is reduced.

    本发明涉及一种用于飞机气源系统换热器的旋流混合装置。一该旋流混合装置包括套筒,套筒包括附连到所述气流系统预冷器的前端和附连到下游管路的后端;其中旋流混合装置包括多个定子叶片,多个定子叶片固定地设置在套筒的内周壁上,相邻的定子叶片沿套筒的内周面彼此隔开,每一个定子叶片相对于气流方向具有迎风面,迎风面相对于气流方向成一倾斜夹角。采用根据本发明的旋流混合装置,换热器出口封头处的加速非均匀温度场的混合,有效解决非均匀温度场带来的温度控制问题,且优化的旋流结构流阻小,降低对性能的影响。
