Abstract

A cooling device applicable to an airplane having a pressurized cabin and a ram air channel for cooling an electronic device arranged in the pressurized cabin, is comprised of a partition wall separating the pressurized cabin from the ram air channel; and a heat exchanger thermally in contact with the electronic device and exposed to the ram air channel so as to radiate heat to a ram air.

Claims

1. A cooling device applicable to an airplane having a pressurized cabin and a ram air channel for cooling an electronic device arranged in the pressurized cabin, comprising:

a partition wall separating the pressurized cabin from the ram air channel; and

a heat exchanger thermally in contact with the electronic device and exposed to the ram air channel so as to radiate heat to a ram air.

2. The cooling device of claim 1, wherein the heat exchanger gets thermally in contact with both faces of the partition wall, one of the faces facing to the pressurized cabin and another of the faces facing to the ram air channel, whereby the heat exchanger and the partition wall constitute a heat transfer path for transmitting heat from the electronic device to the ram air channel.

3. The cooling device of claim 1, wherein the heat exchanger further includes a heat pipe.
