The invention provides an engine compartment cooling device. The device is arranged between an engine air inlet channel and an engine inlet. The engine compartment cooling device comprises: a first metal ring used for forming an airplane gas inlet channel and provided with a plurality of air inlet openings in the circumferential direction; a second metal ring arranged on the outer side of the first metal ring in a sleeving mode, wherein the second metal ring and the first metal ring form an annular gas collecting cavity capable of containing gas, and a plurality of gas outlet openings communicated with the annular gas collecting cavity are formed in the circumferential direction of the second metal ring; and a limiting piece arranged on the outer side of the gas outlet opening and coveringthe gas outlet opening, wherein the limiting piece and the gas outlet opening form a one-way valve which can only exhaust gas from the annular gas collecting cavity to the gas outlet opening. The non-ram gas inlet can be formed in the outer surface of an airplane, so that the gas resistance in flight is reduced, the engine compartment cooling gas inlets are formed in the forefront part of the engine compartment and are annularly and uniformly formed, and cooling gas flow in the engine compartment basically has no flowing dead zone, temperature distribution is uniform, and no local high-temperature zone exists.

    本申请提供了一种发动机舱冷却装置,其设置在发动机进气道与发动机进口之间,发动机舱冷却装置包括:用于构成飞机进气道的第一金属环,第一金属环的周向上设有多个进气开口;套在第一金属环外侧的第二金属环,第二金属环与第一金属环形成能够容纳气体的环形集气腔,第二金属环的周向上也设有多个连通环形集气腔的出气开口;设置在出气开口外侧且覆盖出气开口的限位片,限位片与出气开口形成只能自环形集气腔向出气开口排气的单向活门。本申请可以使飞机外表面形成无冲压的进气口,从而减小飞行中的空气阻力,且发动机舱冷却进气口设置在发动机舱最前部且环向均匀设置,使发动机舱内的冷却空气流基本无流动死区,温度分布均匀,无局部高温区。
