PROBLEM TO BE SOLVED: To make it possible to efficiently cool an aircraft electrically-driven unit by air refrigerant.SOLUTION: Heat exchangers 17, 31 are disposed to be adjacent to electrically-driven units 19, 33, respectively so that air (ventilation air or air outside of an aircraft) drawn in by electric blowers of electric blower units 21, 35 rotating at rotating speeds in response to heating values of the respective electrically-driven units 19, 33 passes through the adjacent heat exchangers 17, 31. Air-cooling capabilities of the corresponding heat exchangers 17, 31 are individually regulated in response to the heating values of the electrically-driven units 19, 33 by controlling the rotating speeds of the electric blowers. This makes it unnecessary to ensure that an entire cooling system of the electrically-driven units 19, 33 always has the air-cooling capabilities including a certain margin on the assumption of, for example, a case where the heating values of all the electrically-driven units 19, 33 increase.SELECTED DRAWING: Figure 1

    【課題】航空機の電動駆動ユニットを空気冷媒によって効率的に冷却できるようにする。【解決手段】各電動駆動ユニット19,33に熱交換器17,31をそれぞれ隣接させて、各電動駆動ユニット19,33の発熱量に応じた回転数で回転する各電動ブロワユニット21,35の電動ブロワにより吸引したエア(ベンチレーションエアや機外の空気)を、対応する電動駆動ユニット19,33に隣接する熱交換器17,31にそれぞれ通過させる。そして、各電動駆動ユニット19,33の発熱量に応じて、対応する熱交換器17,31による空冷能力を電動ブロワの回転数制御により個別に調整する。このため、例えば、全ての電動駆動ユニット19,33の発熱量が増加した場合等を想定して、一定のマージンを含めた高めの空冷能力を電動駆動ユニット19,33の冷却システム全体で常に持たせておく必要をなくすことができる。【選択図】図1
