Forward in flight (IFE) entertainment cooling system

In combination with in an aircraft:

• an in flight entertainment system having in-flight entertainment system electronics;
• a video control cabinet for housing said in flight entertainment system electronics;
• a cooling system for conducting air from outside the aircraft cabin to said video control cabinet;
• control means for venting heated air from said video control cabinet to the outside of the aircraft or to said aircraft cabin depending upon the location of the aircraft and the outside ambient temperature;
• and, wherein said control means vents said heated air into the aircraft cabin when the aircraft is on the ground and the outside ambient temperature (OAT) is less than a predetermined temperature.

A system within an aircraft for exhausting heated air overboard comprising:

• an air/ground signal for detecting air/ground transition from ground made to air mode;
• a forward in-flight entertainment system cooling overflow valve;
• ventilation valves for closing and exhausting heated air overboard by said forward in-flight entertainment system cooling overflow valve upon transition to air mode;
• and
• said forward in-flight entertainment system cooling overflow valve providing overboard flow increasing with altitude and cabin to ambient pressure differential.

In combination with an aircraft having a cargo door, frames and windows:

• a forward in-flight entertainment cooling system;
• supply air provided forward of the cargo door;
• a forward supply fan disposed in a supply manifold forward of the cargo door;
• a supply manifold comprising a plurality of flex ducts running between the frames and windows;
• and
• said forward supply fan providing forced air through said supply manifold.

An exhaust system for use in an aircraft comprising in combination:

• a plurality of video control cabinets;
• an exhaust duct for collecting exhaust air from any of said plurality of video control cabinets;
• said exhaust duct connected to a distribution duct bypassing said plurality of video control cabinets;
• said exhaust system further including a collection manifold, forward exhaust fan and forward smoke detector plumbed across said forward exhaust fan.
