The invention discloses a ventilation cooling device of an engine core bin. An engine comprises the core bin and an outer culvert. The outer culvert comprises an outer culvert outer wall and an outer culvert inner wall. A plurality of air inlet holes are formed in the outer culvert inner wall. The ventilation cooling device is arranged on the outer culvert inner wall and can be adjusted so that the flow of air entering the core bin from the air inlet holes can be controlled. The ventilation cooling device can be switched among the first work position, the second work position and the middle work position, and therefore the core bin can be cooled according to the environment need. According to the ventilation cooling device, the core bin can be effectively ventilated and cooled, the requirement for the temperature of pipelines and accessories in the bin under the high-temperature work state can be met, meanwhile, the effect of the ventilation cooling device on the pneumatic performance of the outer culvert can be small, and the cruising loss is reduced.
