Research on ventilation flow distribution of civil aircraft electronic equipment based on flow resistance simulation

The ventilation and cooling system of electronic equipment in civil aircraft is an important function to ensure the normal operation of the aircraft. Providing sufficient cooling air to each electronic device through flow distribution design is key to ventilation system design. In this article, a ventilation flow distribution method for electronic equipment based on flow resistance simulation is introduced, regarding the layout, interface, and flow resistance characteristics of electronic equipment compartments in civil aircraft. A flow distribution simulation model is established by simulating the flow resistance characteristics of real equipment. Experimental research is conducted based on flow resistance simulation test articles, indicating that this method can efficiently complete the flow distribution design of electronic equipment and achieve high accuracy. This research has provided a high-efficiency method on the design of civil aircraft.
