CFD THERMAL ANALYSIS ON LAPTOP COOLING SYSTEM USING LOOP HEAT PIPE TECHNOLOGY

Science and Technology has begun a new revolution in human life. Due the development in technology, electronic equipments especially laptops ensue to be smaller, lighter and faster. As a high processing unit is involved, laptops are subjected to release a lot of heat, and in turn creating hot spots on the processing unit. Since the cooling system currently employed is not much efficient to drive away the heat in hot spots, it is replaced with modern miniature Loop Heat Pipe (mLHP) technology for enhanced cooling. In addition, this novel passive cooling solution has so many advantages compared to the existing active cooling solutions such as the noise-free operation, lower energy consumption and higher reliability. In this paper, a digital prototype of laptop with the new cooling technique is designed and analyzed using Computational Fluid Dynamics software Fluent. This analysis is carried out with various heat dissipation rates of the heat source 30 W, 32 W, 43 W for different working conditions such as standard use of the notebook, standard use while charging the battery and 100% CPU load respectively. The heat dissipation and distribution for different working conditions are investigated. Based on the results obtained, a contemporary
