Fan cooled system are generally avoided in critical care and operating rooms, thus relying on natural convection or liquid cooling to cool devices and equipment.
42.
Water contained within plastic or metal containment and placed in direct sunlight heats more rapidly and more evenly than solid mass due to natural convection heat transfer.
43.
The use of natural convection air currents ( rather than mechanical devices such as fans ) to circulate air is related, though not strictly solar design.
44.
Water vapor is a lighter gas than other gaseous components of air at the same temperature, so humid air will tend to rise by natural convection.
45.
While in earlier personal computers it was possible to cool most components using natural convection ( passive cooling ), many modern components require more effective active cooling.
46.
In the summer, the convective flow is replaced with cooler near-ambient-temperature Earth replacement air, and the warm air exhausts by natural convection.
47.
CH 2 uses similar strategies with its system by effectively using natural convection, ventilation stacks, thermal mass, phase change material, and water for cooling.
48.
The high-mass air well design attempts to cool a large mass of masonry with cool nighttime air entering the structure due to breezes or natural convection.
49.
A solar chimney can use natural convection ( warm air rising ) to create a vacuum to draw filtered passive cooling tube air through the largest diameter cooling tubes.
50.
In other cases, natural buoyancy forces alone are entirely responsible for fluid motion when the fluid is heated, and this process is called " natural convection ".
