Patent ID: 7920382

Claim:
Aircraft electronics cooling apparatus comprising: a liquid cooling system onboard an aircraft, including a coolant circulating therein; an electronic device to be cooled; and a cooling circuit operatively connecting the electronic device to the liquid cooling system; wherein the aircraft electronics cooling apparatus is configured such that the coolant flows from the liquid cooling system to the cooling circuit, where the coolant flows serially and/or in parallel through at least two of the following: a first heat exchanger through which flows the coolant and air which is cooled by the coolant the cooled air being directed to the electronic device to be cooled after exiting the first heat exchanger, a second heat exchanger through which flows the coolant and air which is cooled by the coolant, wherein the air entering the heat exchanger passes the electronic device to be cooled before entering the second heat exchanger, a board of the electronic device to be cooled, a third heat exchanger which is arranged in a housing below the electronic device to be cooled and is spaced therefrom, the third heat exchanger including at least one respective opening for outflow of air arranged above the electronic device to be cooled and further including at least one respective opening for inflow arranged below the third heat exchanger, a housing in which the electronic device to be cooled is arranged, a heat sink on which the electronic device to be cooled is arranged, and around the electronic device to be cooled.
