The electronic equipment is also separated into two categories by the cooling method used. The two cooling techniques considered in this thesis are ambient cooling (where heat is transferred by free convection and radiation) and forced air cooling (where heat is transferred to cold air supplied by the aircraft ECS).

Air-Cooled, Pin Fin Coldwall Design For Operation At ...

In cases of new aircraft designs, the electronic dissipations of all of the electronic systems to be used on the aircraft are contemplated during the design of the aircraft ECS. For electronic equipment, which is air-cooled by a fan, the variation of flight altitudes results in variable air densities, which become quite low at the higher altitudes.

Diesel In The Sky: Aviation And The Diesel Engine

The first successful diesel-powered aircraft was the Junkers JU-86. Junkers was a German manufacturer of aircraft in the mid-1900s. Primarily producing aircraft for the Luftwaffe, it was responsible for many well-known airframes, and the first use of a diesel powerplant. The JU-86 was a large, twin-engine bomber and transport aircraft.

Thermal Design of Military Electronic Equipment

Most electronic chips use air-cooled heat dissipation, and water-cooled heat dissipation devices are used for devices that consume a lot of heat. But for electronic devices in space flight or outer space, this kind of heat dissipation method is not advisable, and a more compact liquid cooling system must be designed.
