Computer cooling system

A computer system typically comprises a plurality of electronic components which may include a central processing unit (CPU), a chipset, and a memory. With the advent of the increased heat developed by such electronic components, modern computer systems require increased ventilation to move cooling air through the unit. A failure to provide adequate ventilation through a modern computer system may increase the probability of computer failure due to overheating and may result in damage to the electronics and/or peripheral units. Heat dissipation in a computer system that typically includes a central processing unit (CPU) is always a significant concern. This is due to the fact that heat is typically generated in the computer system during operation. Due to the heat generation from this CPU the temperature of the interior of the personal computer rises, with the result that the operation of the CPU may sometimes become abnormal, that the operation of other circuits of the personal computer may sometimes become unstable. The temperature rise in the computer system may cause the computer system to malfunction. A thermal management system is typically used to remove heat from a computer system. For cooling the semiconductor device of a computer system, there are various known techniques, such as thermal conduction or air-cooling, or the use of a heat pipe, or liquid cooling. It is typical to use a heat sink with the central processing unit of a laptop computer to increase the heat-dissipating surface area of the central processing unit for more effective cooling. Heat sinks are often attached to heat generating electronic components, such as microprocessors, and fans are also used for forced air cooling of the electronic components. Specifically, with cooling by the use of forced air, an air blower or fan is provided inside the electronic apparatus, thereby achieving a cooling of the semiconductor device therein by forced circulation of air thereon. Cooling fans are commonly used to blow air over the heat generating electronic components and also to blow the accumulated hot air away from the atmosphere surrounding the components to thereby lower the air temperature and allow for more heat to be radiated out of the component. In liquid cooling, a liquid is pumped through a closed loop cooling system and removes heat from heat exchangers that are in thermal contact with each of the processor chips.
