SYSTEM AND METHOD FOR COOLING AT LEAST ONE HEAT-PRODUCING DEVICE IN AN AIRCRAFT

摘要

A system is provided for cooling at least one heat producing device in an aircraft that includes, but is not limited to at least one coolant circuit. A coolant absorbs heat from the heat producing device and dissipates heat, by way of a heat dissipation device, to the surroundings of the aircraft. A temperature spreading device reduces the temperature of the coolant in a feed line of the coolant circuit and increases the heat dissipation temperature of the heat dissipation device relative to the temperature of the coolant in a return line of the coolant circuit. In this manner ram air ducts that are commonly used in the state of the art or systems that consume pre-cooled air can be avoided, which in particular when the aircraft is situated on the ground on hot days can render avionics cooling or the like difficult.
