description	The invention discloses a fan pneumatic structure. The fan pneumatic structure comprises a centrifugal impeller, radial guide vanes (2) and axial guide vanes (3); the radial guide vanes (2) are located at outlets of centrifugal vanes (1) of the centrifugal impeller; the axial guide vanes (3) are located at outlets of the radial guide vanes (2); airflow sequentially passes through the centrifugal vanes (1) of the centrifugal impeller, the radial guide vanes (2) and the axial guide vanes (3), and axial air intake and axial air exhaust are realized. According to the fan pneumatic structure, the respective advantages of a centrifugal fan and axial flow air are effectively utilized, the design problem that a "small flow, large pressure rising" fan cannot carry out axial air intake/exhaust is solved, and a novel idea is provided for airborne fan design. 本发明公开了一种风机气动结构，包括离心叶轮、径向导叶(2)和轴向导叶(3)；所述径向导叶(2)位于离心叶轮的离心叶片(1)的出口；所述轴向导叶(3)位于径向导叶(2)的出口；气流依次经离心叶轮的离心叶片(1)、径向导叶(2)和轴向导叶(3)，轴向进气，轴向排气。本发明有效利用了离心风机和轴流风各自的优点，解决了"小流量、大压升
