- While in operation, a heat-generating element such as a central processing unit (CPU) of a computer will generate high temperature and heat, and the heat has to be dissipated promptly for allowing the heat-generating element to continue to work normally.
- Most of the conventional heat dissipating methods conduct heat dissipation by using a heat dissipation base and a heat dissipation fin contacting the heat-generating element. However, since the heat conduction or natural convection occurring in the conventional heat dissipating methods does not provide sufficient heat dissipation, its heat dissipation effect is not good enough. In order to lower the temperature of the heat-generating element and protect its performance and operation life, additional fan and motor are generally needed for conducting heat dissipation on the heat-generating element by forced convection.
- However, the fan and motor have the disadvantages of high production cost, big volume (size), large power consumption and noise occurrence. Moreover, when the fan is operated to expel hot air and suck in cool air, the dusts in the air will be sucked in with the strong air flow and be adsorbed inside the main body (such as the computer) on which the heat-generating element is disposed, and then the dusts will be gradually accumulated on the rotating axle or blades of the fan, thus causing the fan to be seized and fail to work continuously, eventually resulting in the overheating breakdown of the heat-generating element.
- On the other hand, another conventional heat dissipating method is a liquid cooling method, wherein a heat conducting pipe containing water or liquid is disposed to contact the heat-generating element, and a motor is used to drive the pump to circulate the water or liquid for achieving the purpose of dissipating the heat of the heat-generating element.
