In the computer, the CPU heat large CPU faster, power consumption, the greater the heat more. General cooling method relies mainly on the heat sink and fan. The bottom and the upper part of the motherboard, each with a metal heat sink. The location of the CPU, and assist in the cooling system to absorb the heat generated from the CPU. The cooling fan does not start, low air flow and high air flow and three files, depending on CPU temperature. The greatest advantage of this cooling method is low cost, it was accepted by most PC manufacturers.
In addition to cooling, the keyboard convection cooling is a very creative approach. We know that the laptop computer is thin, when the Gateway MP-07F33U4-4424H Keyboard
to the motherboard, the bottom of the keyboard will be, and board contacts can just use the keyboard at the bottom of conduction of heat generated by the CPU out. The structure of the keyboard, each key has four holes, the heat is then discharged through the button hole, when the hot air discharged from the button hole, and the air flows from the button hole to replace the hot air.
In a large number of cooling technology, water-cooled heat pipe technology is IBM proposed a very effective cooling technology. The initial idea is to dig ice cream spoon, handle the heat through the air traffic control-oriented frozen ice cream, melting more soft can be dug out after eating. Cooling tube within the fiber and liquid heat transfer medium (mostly water), drawn into the vacuum tube, a section close to the CPU, the other end away from the CPU. It works is: under vacuum, the boiling point of liquid thermal conductivity of the medium is very low, if a section of the tube is heated, the media will evaporate, the tropics to the other end of the cooling and then flow back, and so forth, the heat is constantly being brought to go. The heat pipe has many advantages, no moving parts, no noise, do not consume energy, while a long time to work effectively.
In addition to the heat pipe technology in IBM's unique Toshiba laptop, cold, hot-plate cooling technology. Thermal efficiency has increased by approximately 6.5 times, so that the laptop cooling issues are effectively addressed. Many brand name notebook computers using heat pipe cooling, convection cooling keyboard, a thermostatically controlled fan three cooling methods.
Did not yet have the software to directly control the laptop fan is running, but by the HTL instruction can effectively reduce the CPU's heat. Windows2000/XP has built-in support HTL instructions.
