Air cooling

Definitions

  • Webster's Revised Unabridged Dictionary
    • Air cooling In devices generating heat, such as gasoline-engine motor vehicles, the cooling of the device by increasing its radiating surface by means of ribs or radiators, and placing it so that it is exposed to a current of air. Cf. Water cooling.

Break the ivy too lavish!
Buds for a carpet ravish!

And the winds in her hair kept locking
Their fingers cool and bare.

Soft airs breathe, and green leaves tremble,
And cool fountains flow.

Flower-sweet and cool with salt sea air,
And watched beside his bed, for whom

Rich coolness wraps the air about,
Whilst through clear pools electric flashes
Betray the watchful trout.

In science:

As warm air rises, it cools almost adiabatically – this is known as the “lapse rate”, and stability of the atmosphere ensures that temperatures fall no faster than this rate with altitude.
Climate Sensitivity and the Response of Temperature to CO$_2$
When air holding water vapor rises and cools, some of the water condenses and releases heat, resulting in warmer air at a given altitude, and a lower lapse rate.
Climate Sensitivity and the Response of Temperature to CO$_2$
Power consumption (mainly by the output circuit) should be < 10 mW/channel in order to keep the detector system at ∼ −60 ◦C with a gentle air (cool N2 gas) flow.
R&D status of FPCCD VTX
Pierrehumbert (1995) examined the local runaway greenhouse in Earth’s tropics, highlighting the importance of dry air columns for cooling.
The Runaway Greenhouse: implications for future climate change, geoengineering and planetary atmospheres
Given the dominance of convection, the vertical temperature profile is set by the behaviour of rising air, following a moist adiabatic lapse rate (air cools as it rises, but part of this cooling is offset by latent heat release as water condenses from the rising air).
The Runaway Greenhouse: implications for future climate change, geoengineering and planetary atmospheres
The modest power dissipated and the possibility to operate the sensor at room temperature, allow to rely on a gentle air flow (a few m/s) for the cooling.
Development of Single- and Double-sided Ladders for the ILD Vertex Detectors
The macro-module containers employ direct liquid cooling to eliminate the space requirements for CRAC units. Also, no space is required for human service or for high volume airflow. As a result, the system density can be much higher than is possible with conventional air-cooled racks.
Architecture for Modular Data Centers
After each evaporation, the set up was cooled down to room temperature and then exposed to air (in order to extract the photo-cathode), therefore the parasitic layer adsorbed water from the ambient air.

At high altitude the air expands, cools and air steam condenses in water collector.

Above 16 cm s−1 , the combustion became fuel-limited as the increased air flow increased convective cooling and slowed pyrolysis and hence ROS.

Including a convective cooling term to the ambient air apparently brought the prediction down to the observed ROS but this was not detailed.

ILC Reference Design Report Volume 1 - Executive Summary
The greater part of the heat is dissipated in the anode of a tetrode or in the collector of a linear-beam tube. These electrodes are normally cooled in one of three ways: by blown air (at low power levels), by pumped liquid (usually de-ionized water), or by vapour phase cooling.
RF power generation
Either of these effects can degrade the effectiveness of the cooling system and cause premature failure of the tube. In blown-air systems careful filtering of the air is necessary for the same reasons.
RF power generation
The highest variance is found at ±30◦ N and approximately 100◦ E of the substellar point, where the equatorial jet has carried warm air from the dayside to the cool nightside, making the fluctuations caused by its north-south movement most apparent.
