A porous micro heat sink system is presented for cooling of high power LEDs, which has high heat transport capability. The operational principle and heat transfer characteristics of porous micro heat sink are analyzed. Numerical model for the micro heat sink is proposed to describe liquid flow and heat transfer based on the local thermal equilibrium of porous media, and it is solved with SIMPLE algorithm...
Finite element simulations have been performed for the dynamics of heating and cooling of a single spherical gold nanoparticle and surrounding fluid environment by laser pulses of nanosecond duration in the limit of validity of Mie theory. Thermal and dielectric property changes of the surrounding medium are taken into account in the model. It has been shown that such changes significantly affect...
This paper specifically addresses the thermal characteristics of the miniature loop heat pipe (mLHP) with flat disk shaped evaporator for the thermal control of the compact electronic devices. The loop was made of stainless steel with sintered nickel wick and ammonia as the working fluid. Detail study was conducted on the start-up reliability of the mLHP and the operating characteristics under different...
Immersion cooling of power electronic equipment can avoid device derating at elevated ambient temperatures and thereby increase power density. In this paper, a test bench is presented that can be used to characterize the heat transfer from fluid-immersed electrical components inside cylindrical volumes. Since the thermal properties of coolants are themselves temperature dependent and vary locally,...
In order to study fluid state influence on stator temperature of generator, this paper applies heat transfer theory and hydromechanics to analyze water cooling system. The water velocity was studied when the water cooling winding was blocked in turbo-generators and the stator 3D temperature field was calculated by the thermal network method. The result showed different water velocity could be lead...
