Abstract

There is provided a telecommunications network equipment unit, comprising a cooling system. The cooling system comprises an air input channel and an exhaust air output, wherein the exhaust air output is separate from the air input channel. The cooling system further comprises a plurality of air conduits. The plurality of air conduits is arranged such that heat can be transferred from respective ones of a plurality of devices in the telecommunications network equipment to air passing through respective ones of the plurality of air conduits. Each of the plurality of air conduits is arranged to receive a respective outflow of air from the air input channel and to direct said outflow of air therethrough to the exhaust air output. There is further provided telecommunications network equipment comprising one or more telecommunications network equipment units.

Dependent claims

A telecommunications network equipment unit, comprising:

a cooling system;
wherein the cooling system comprises:
an air input channel;
an exhaust air output, wherein the exhaust air output is separate from the air input channel;
and
a plurality of air conduits, wherein the plurality of air conduits is arranged such that heat can be transferred from respective ones of a plurality of devices in the telecommunications network equipment to air passing through respective ones of the plurality of air conduits, wherein each of the plurality of air conduits is arranged to receive a respective outflow of air from the air input channel and to direct said outflow of air therethrough to the exhaust air output, wherein each of the plurality of air conduits is physically separated from adjacent air conduits by solid walls extending along a length of the air conduits from the air input channel to the exhaust air output, and wherein the plurality of air conduits comprises a heat conductive material arranged to thermally couple with the plurality of devices for transferring heat from the devices to air flowing through the air conduits.
