The invention discloses a lubricating oil heat dissipation system of an auxiliary power device for an airplane. The lubricating oil heat dissipation system comprises an auxiliary power device cabin, an airplane air inlet channel, an integral air inlet unit, a lubricating oil unit and an auxiliary power device body. The auxiliary power device cabin is mounted at the tail of the aircraft; one end of the airplane air inlet channel is connected with the auxiliary power device cabin; the other end of the airplane air inlet channel is connected with the integral air inlet unit; the integral air inlet unit is connected with the auxiliary power device body; and the integral air inlet unit is connected with the lubricating oil unit. Compared with a fan cooling mode, a rotating part is omitted, power consumption is reduced, the structural complexity is reduced, and reliability is enhanced; compared with an exhaust ejection heat dissipation mode, an exhaust ejector is omitted, so that the structure is more compact; the lubricating oil radiator is placed in a cold end area, and the problem that cooling air needs to flow through a high-temperature area to be heated, and consequently the cooling effect is poor is solved.

    本发明公开了一种飞机用辅助动力装置滑油散热系统,包括:辅助动力装置舱、飞机进气道、整体式进气单元、滑油单元和辅助动力装置本体;所述辅助动力装置舱安装于飞机尾部;所述飞机进气道一端与辅助动力装置舱相连接;所述飞机进气道另一端与整体式进气单元连接;所述整体式进气单元与辅助动力装置本体连接;所述整体式进气单元与滑油单元连接。本发明相对于风扇冷却方式,取消了旋转部件,减少了功率消耗,降低了结构复杂程度,增强可靠性;相对于排气引射散热方式,取消了排气引射器,使得结构更加紧凑;滑油散热器放置于冷端区域,克服了冷却空气需要流经高温区加热,导致冷却效果差的问题。
