Method for realizing ventilation and cooling of aeronautic electric equipment by using cockpit exhaust air on basis of double exhaust valves

The invention provides a method for realizing ventilation and cooling of aeronautic electric equipment by using cockpit exhaust air on the basis of double exhaust valves, and belongs to the technical field of airplane environment control. A cockpit exhaust valve and an equipment cooling exhaust valve are arranged in an airplane cockpit; the cockpit exhaust valve regulates the cockpit pressure according to a preset cockpit pressure system; and the equipment cooling exhaust valve regulates the equipment inlet pressure or the equipment cooling exhaust valve outlet pressure according to the preset pressure system, so that the cockpit exhaust air is enabled to be sufficient for the ventilation and the cooling of the electronic equipment.
