The invention belongs to the field of aviation environment control system design, and particularly relates to an aircraft heat exchange system based on bidirectional injection. Comprising a stamping air inlet channel, and the stamping air inlet channel comprises a stamping inlet section (1), a transition injection section (4) and a stamping outlet section; heat exchangers including an air-liquid heat exchanger (2), a first air-air heat exchanger and a second air-air heat exchanger; air cycle machines including a first air cycle machine and a second air cycle machine; according to the aircraft heat exchange system based on two-way injection, the flow of ram air entering the left side and the right side of the ram outlet channel is limited according to the principle of constant entropy injection, meanwhile, the cold edge of the heat exchanger and the ram air inlet channel are integrally designed, and the flow resistance of the heat exchanger set is combined to be matched with the dynamic pressure brought by the ram air; and the problems of fan overspeed, windmill effect, surge and the like of the air cycle machine are effectively avoided.

    本申请属于航空环境控制系统设计领域,特别涉及一种基于双向引射的飞机换热系统。包括:冲压进气道,所述冲压进气道包括冲压进口段(1)、过渡引射段(4)以及冲压出口段;热交换器,所述热交换器包括空‑液热交换器(2)、第一空‑空热交换器以及第二空‑空热交换器;空气循环机,所述空气循环机包括第一空气循环机以及第二空气循环机;本申请的基于双向引射的飞机换热系统,利用定熵引射的原理限制了进入左侧以及右侧冲压出口通道的冲压空气流量,同时将热交换器的冷边与冲压进气道一体化设计,结合热交换器组的流阻匹配冲压空气带来的动压,有效规避空气循环机的风扇超速、风车效应、喘振等问题。
