Redundant integrated liquid cooling system for avionics

Cooling system for cooling at least one first heat producing device provided in a means of transport, for example in an aircraft, the cooling system comprising:

• at least one first liquid circuit, and
• at least one first heat exchanger assigned to the first liquid circuit, the first liquid circuit, for cooling the at least one first heat producing device provided on board the means of transport, being configured to absorb heat of the first heat producing device by means of a cooling liquid circulating in the first liquid circuit and dissipate heat to the first heat exchanger, the first heat exchanger being coupled in such a manner to a first air-guiding system available on board the means of transport, for example a first exhaust air system available on board the means of transport, that exhaust air extracted from the first air-guiding system, for example the first exhaust air system, is suppliable to the first heat exchanger in order to recool the cooling liquid.
