Download Free PDF. Passive Cooling Techniques. Joel Gamboc. • It rely on natural heat-sinks to remove heat from the building. They derive cooling directly from evaporation, convection, and radiation without using any intermediate electrical devices. the rising hot air is allowed to escape which in turn does two.

B. Stable air, altitude increases, temp increases C. The atmospheric conditions in a location at a specific time D. Hot air rises, cools, then sinks E. The weather as recorded over time AB. Wind being deflected due to earth's rotation AC. Plants use solar radiation and CO 2 to make energy and release O 2 AD. Energy from the sun AE. and heat will be transferred from this layer to the outer layers of air. Fig. 1: Natural convection heat transfer from a hot body. The temperature of the air adjacent to the hot object is higher, thus its density is lower. As a result, the heated air rises. This movement is called the natural convection current. Note. When air is heated, it expands, becomes lighter and goes up. Cold air is denser and heavy. That is why it tends to sink down. When hot air rises, cold air from surrounding area rushes there to fill in the gap. That is how air circulation takes place. AIR

natural or forced. Hot or cold fluids can add or remove heat. Natural convection is caused by density differences. Hot air rises because it is less dense than cold air, so air will rise above a heater and sink near a cold window. Forced convection refers to fluids being pushed around by outside forces. 31 ratings4 reviews. Hot Air Rises and Heat Sinks: Everything You Know About Cooling Electronics Is Wrong is a collection of myths, mistakes, and "lessons learned" from practicing engineers involved in the field of electronic equipment cooling. Through anecdotes and stories based on his experiences at Tellabs Operations, Inc. Tony Kordyban. Other examples of convection are: boiling a pot of water on the stove; using a hot radiator to warm the air in a room; and using heated air to make a hot-air balloon rise up into the sky. Radiation So we’ve learned that conduction moves heat easiest through solids, and convection moves heat through liquids and gases.
