The invention belongs to the technical field of helicopter structural design. The invention relates to an avionics equipment cabin with a ventilation loop. The equipment cabin adopts an upper-lower double-layer equipment platform design; the equipment cabin platform is integrally provided with a ventilation loop, an exhaust fan is arranged at the bottom of the equipment cabin platform, negative pressure is formed in the cabin, cold air is sucked into the equipment cabin from a ventilation opening cover of the machine body, the air inlet flow is increased, and the whole passage is smooth; a horizontal plate is transversely added to the equipment compartment, the horizontal plate, the frame beam and the skin form a box section type sub-compartment, the horizontal plate can transmit loads, and equipment is suitable for being placed in the sub-compartment.

    本发明属于直升机结构设计技术领域,涉及一种带通风回路的航空电子设备舱,设备舱采用上下双层设备平台设计,避免设备布局杂乱,并由杂乱布置引起的线缆干涉以及散热困难,设备舱平台通过整体设置通风回路,在底部设置排气风扇,舱内形成负压,将冷空气从机体通风口盖吸入设备舱,增大进空气流量,整个通路顺畅;在设备舱横向加水平板,与框梁及蒙皮形成盒段式子舱室,水平板可传递载荷,子舱室内适用于放置设备。
