about the obsolete theory of globalcooling the theory positing an overall cooling of the Earth and perhaps the commencement of glaciation or even an ice age Globalcooling Before the concept of plate tectonics , globalcooling was a reference to a Geophysics geophysical theory by James Dwight Dana , also referred to as the contracting earth theory. It suggested that the Earth had been in a molten state, and features such as mountains formed as it cooled and shrank. ref http www.bbm.me.uk portsdown PH 061 History a.htm The History of Continental Drift Before Wegener Bot generated title ref As the interior of the Earth cooled and shrank, the rigid crust would have to shrink and crumple. The crumpling could produce features such as mountain ranges. Application The Earth was compared to a cooling ball of iron, or a steam boiler with shifting boiler plates. By the early 1900s, it was known that temperature increased with increasing depth. With the thickness of the crust, the boiler plates , being estimated at ten to fifty miles, the downward pressure would be hundreds of thousands of pounds per square inch. Although groundwater was expected to turn to steam at a great depth, usually the downward pressure would contain any steam. Steam s effect upon molten rock was suspected of being a cause of volcanoes and earthquakes, as it had been noticed that most volcanoes are near water. It was not clear whether the molten rock from volcanoes had its origin in the molten rock under the crust, or if increased heat due to pressure under mountains caused the rock to melt. One of the reasons for volcanoes was as a way in which the contracting earth disposes of the matter it can no longer contain ... status This theory is now disproven and considered obsolete.

DISPLAYTITLE H sub 2 sub Ceramic cooling H sub 2 sub Ceramic cooling also called H sub 2 sub C or Hot to Cold is a computer cooling product offered as an option in Dell s XPS gaming systems, advertised specifically as facilitating Cpu CPU overclocking . H sub 2 sub C is a two stage Liquid TEC hybrid cooling system that combines a liquid to air heat exchanger much like a liquid radiator , a Thermoelectric cooling thermoelectric fluid chiller , and control circuitry to optimize CPU cooling with minimal power. According to Dell, the cooling efficiency of H sub 2 sub C contributes to PC systems that are cooler in over clocked mode and potentially quieter in normal operating mode. By cooling the CPU below what is possible with traditional forced air convection or water cooling systems, but preventing the temperature from falling below ambient room temperature , H sub 2 sub C is advertised as extending CPU life while eliminating the risk of humidity condensation .

Oil cooling refers to a process whereby heat is displaced from a hotter object, into a cooler oil and is the principle behind Cooler oil oil cooler devices. The oil carrying the displaced heat usually passes through a cooling unit such as a radiator or less commonly a gas decompresser. The cooled oil repeats this cycle, to continuously remove heat from the object. For and against Advantages Oil has a higher boiling point than water, so it can be used to cool items 100 C or higher. Oil is an electrical insulator thus, it can be used inside of or in direct contact with electrical components. Disadvantages Coolant oil may be limited to cooling objects under approximately 200 C 300 C. Parts are hard to take out and put in after the oil is put in. Gas cooling For the instance where an object to be cooled is greater in temperature than the range a cooling oil can remain stable, a compressed cooled gas would be used. As compressed gas is decompressed, heat is absorbed from surroundings of the gas, in particular, the hot object.

File Cooling curve pure metal.svg 500px The initial point of the graph is the starting temperature of the matter, here noted as the pouring temperature . When the phase change occurs there is a thermal arrest , that is the temperature stays constant. This is because the matter has more internal energy as a liquid or gas than in the state that it is cooling to. The amount of energy required for a phase change is known as latent heat . The cooling rate is the slope of the cooling curve at any point. In the part of the curve where the temperature decreases, the kinetic energy also decreases while the potential energy stays the same.

Thermotunnel cooling is similar to thermionic emission cooling in that fast moving electron s carry heat across a gap but cannot return due to a voltage difference. The problem with using thermal electrons to carry heat is the fact that, due to the high work function of metal s, which are the only practical emitters, the lowest cooling temperate is around 600 C clearly not useful except in the most unusual applications. Thermotunnel cooling avoids this problem by making the gap narrow enough that electrons can tunnel across the gap, carrying the heat with them. The problem with this approach has been getting two surfaces near enough that they can tunnel over a large area, yet not touch at any point, which would short the device out preventing it from doing any useful cooling. Cool Chips is a startup trying to optimise a new process for production of these very close surfaces in preparation for selling practical devices. Their approach is to make a five nanometer spacer layer in a special sandwich of materials. Once the chip is assembled, the spacer layer is chemically removed and tiny piezoelectric actuator s maintain the precise spacing required. At this point no devices are available commercially as the technology is still undergoing refinement.
