Abstract:
Most of the current available laptop cooling pad is designed in the pattern of covers the entire chassis of laptop. This type of pattern lead to a problem of low ventilation efficiency when the laptop cooling pad is operates. The aim of this project is to search for a cooling method that capable to increase laptop cooling pad ventilation efficiency.
In order to achieved the aim, three objectives were set which included designed of heat sensing circuit, developed of adjustable fan position laptop cooling pad and evaluation of cooling methods and laptop cooling pads. A heat sensing circuit, which is powered by pheriparal interface controller (PIC), and an adjustable fan position laptop cooling pad was fabricated. Evaluation of several cooling methods and laptop
cooling pads were carried out in a controlled room temperature. As a result, the developed laptop cooling pad in this project has the highest ventilation efficiency of 1 l .3 °C/Watt. Laptop cooling pad ventilation efficiency can be enhances by implant a proper cooling method on it. This is important because it help to reduce electrical energy consumption and also provide convenient to laptop's user.
