Abstract

The invention belongs to the technical field of helicopter structure design, and relates to an avionics equipment cabin with a ventilation circuit. The equipment cabin adopts an upper and lower double-layer equipment platform design to avoid messy equipment layout, cable interference and heat dissipation difficulties caused by the messy layout. The cabin platform is equipped with a ventilation circuit as a whole, and an exhaust fan is installed at the bottom to form a negative pressure in the cabin, and the cold air is sucked into the equipment cabin from the air vent cover of the body, increasing the air flow rate, and the entire passage is smooth; A box-section sub-compartment is formed with the frame beam and the skin, the horizontal plate can transmit the load, and the sub-compartment is suitable for placing equipment.

Description

technical field [0001] The invention belongs to the technical field of helicopter structure design, and relates to an avionics cabin with a ventilation circuit. Background technique [0002] In order to meet the functional requirements of the helicopter, a large number of electronic equipment and computers are arranged on the helicopter structural installation platform. In order to arrange the equipment and prevent the equipment from exceeding the preset temperature limit and cause it to fail to work normally, it is necessary to have a suitable equipment cabin platform and heat dissipation channels. Designed to meet the needs of electronic equipment installation and heat dissipation. [0003] At present, the heat dissipation of electronic equipment arranged on the helicopter installation platform is mainly passive, and the air inlet is opened on the side of the cabin. Through the relative speed of the helicopter flight, the relative air flow enters the cabin to dissipate hea...
