Study on forced air convection cooling for electronic assemblies

LI Bin, TAO Wenquan, HE Yaling

Frontiers in Energy 2008, Volume 2, Issue 2,   Pages 158-163 doi: 10.1007/s11708-008-0009-2

Abstract: The slotted fin concept was employed to improve the air cooling performance of plate-fin in heat sinks. Numerical simulations of laminar heat transfer and flow pressure drop were conducted for the integral plate fin, discrete plate fin and discrete slotted fin heat sinks. It is found that the performance of the discrete plate fin is better than that of the integral continuum plate fin and the performance of slotted fin is better than that of the discrete plate fin at the same pumping power of the fan. A new type of heat sink characterized by discrete and slotted fin surfaces with thinner fins and smaller spaces between fins is then proposed. Preliminary computation shows that this type of heat sink may be useful for the next generation of higher thermal load CPUs. The limit of cooling capacity for air-cooling techniques was also addressed.

The study of forced vibration for threetower suspension bridge under moving loads

Feng Zhaoxiang,Chen Liang and Miu Changqing

Strategic Study of CAE 2012, Volume 14, Issue 5,   Pages 80-84

Abstract:

Taking Taizhou Bridge for example, dynamic characteristics of the finite element model are analyzed and then the effects of different moving speeds and loads on dynamic response of three-tower twospan suspension bridge are studied. The result demonstrates that vertical bending of natural frequency is approximately 0.08 Hz, which is far below natural frequency loading truck, and will not form resonance condition. The response of force and displacement of three-tower twospan continuous suspension bridge under simply moving loads and equivalent static loads are the same. The structural will be greater when moving loads quantity and speed become greater and they have similar positive relationship. However, the load amplification factor of structural force and displacement does not vary with the quantity change of moving loads.

Keywords： dynamic characteristics     forced vibration     response     load amplification factor
