Patent ID: 8707721

Claim:
A cooling system for an aircraft, comprising: a ram air channel for the aircraft; an air inlet through which air from the environment of the aircraft enters the ram air channel; an air outlet through which air emerges from the ram air channel; a heat exchanger of a cabin air conditioning system, the heat exchanger being arranged in the ram air channel and connected to a cabin of the aircraft so as to supply air cooled by the ram air flowing through the ram air channel to the cabin; a distribution line connected to the ram air channel upstream of the heat exchanger, and adapted to ventilate an installation space of at least one heat-loaded component of the cabin air conditioning system; a ventilation device arranged upstream of the distribution line and in fluid communication with the rain air channel and the distribution line such that the ventilation device is adapted to induce an air flow through the heat exchanger and through the distribution line; a temperature detection device which detects the temperature of air flowing out of the heat exchanger to the cabin; and a control device configured to determine if the air flowing out of the heat exchanger to the cabin exceeds a temperature threshold, wherein a one-way valve is arranged in the ram air channel which causes flow of the air in the ram air channel only from the air inlet to the air outlet, and wherein the ram air channel is divided into first and second parallel flow branches, the one-way valve being arranged in the first branch and the ventilation device being arranged the second branch.
