The IR detector was passively cooled at 115K, and the visible light detector maintained at 300K.
Wine cellars can be either active or passively cooled.
These detectors were passively cooled and operate in the temperature range 35 to 55 C. This detector had 6 energy channels, covering the range 5-20 keV.
The 4.6 million transistor CPU is cooled passively by an aluminum heatspreader that makes contact with a steel heat sink above.
The RCP, like the CPU, is passively cooled by an aluminum heatspreader that makes contact with a steel heat sink above.
Passively cooled, Eastgate uses only 10% of the energy needed by a similar conventionally cooled building.
The superheated vapor travels under pressure through coils or tubes comprising the condenser, which are passively cooled by exposure to air in the room.
If a circular building is aerodynamically smooth, and cooler than the ground, it can be passively cooled by the "dome effect."
The output transistors of solid-state amplifiers can be passively cooled by using metal fins called heatsinks to radiate away the heat.
Similar to the Trans-Alaska Pipeline System portions of the track are also passively cooled with ammonia based heat exchangers.
