To provide a duct structure of a cooling device capable of suppressing occurrence of condensation in a cooling air duct at the time of cooling is off.SOLUTION: A duct structure of a cooling device includes: a duct part 41 through which cooling air cooled by a cooling part of a cooling device provided in an upper part of a vehicle passes; an air outlet 42 provided in a lower surface of the duct part 41; a communication port 12b provided in a side surface of the duct part 41; and a valve 11 that opens and closes the communication port 12b. The communication port 12b is inclined such that an upper part thereof approaches the valve 11. The valve 11 is configured such that an upper part thereof is rotatably supported and the valve 11 becomes perpendicular in the vertical direction due to dead weight. By a wind pressure when the cooling air passes at the time of cooling is on, the valve 11 becomes closed, and becomes opened when cooling is off.SELECTED DRAWING: Figure 3
【課題】冷房オフ時に冷風ダクトにおける結露の発生を抑制することができるようにした冷却装置のダクト構造を提供する。【解決手段】車両の上部に備えられる冷却装置の冷却部により冷却された冷風が通過するダクト部41と、ダクト部41の下面に設けられる吹出口42と、ダクト部41の側面に設けられる連通口12bと、連通口12bを開閉する弁11と、を備え、連通口12bは上部が弁側11に近づくように傾斜され、弁11は上部が回動可能に支持されると共に、自重により上下方向に垂直となるように構成され、冷房オン時の冷風通過時の風圧により閉となり、冷房オフ時に開となる。【選択図】図3
