The invention relates to the field of commercial aircraft application, in particular to a ram air collecting diffuser for an aircraft air conditioning system. Which comprises a device body which is respectively connected with an air circulation machine fan and a heat exchanger, and is characterized in that the device body comprises an air collection cylinder and a diffusion cylinder arranged in the air collection cylinder, and a one-way valve is arranged in the diffusion cylinder; through the device, ram air entering the air conditioning assembly can be smoothly exhausted (in the taxiing, climbing, cruising and landing stages of an airplane), the heat exchange efficiency of an air conditioning system when the airplane is on the ground or at a low altitude is improved, flowing of the ram air at the high altitude is not affected, the opening degree of the valve can be automatically adjusted through the air pressure difference, the opening degree of the valve is limited, and the service life of the air conditioning assembly is prolonged. Therefore, ram air can be smoothly exhausted under different working conditions.
本发明涉及商用飞机应用领域,具体涉及一种飞机空调系统用冲压空气集气扩散器。包括装置本体,其装置本体分别与空气循环机风扇相连以及热交换器相连,其特征在于,所述装置本体包括集气筒以及安装于集气筒内部的扩散筒,所述扩散筒内安装有单向活门,通过本装置可以使进入空调组件的冲压空气可顺利排出(在飞机滑行、爬升、巡航、降落阶段),提高飞机在地面或低空时空调系统的换热效率,且不影响高空时冲压空气的流动,本装置可通过空气压力差来自动调节活门开度,并且限制活门开度,从而实现在不同工况下冲压空气的顺利排出。
