摘要：
The flow boiling characteristics in constructal tree-shaped minichannel nets are numerically investigated using a one-dimensional model. The pump power requirement, pressure drop, temperature difference and thermal efficiency of the constructal tree-shaped minichannel are evaluated and compared with those of the corresponding traditional serpentine channel. The results indicated that the flow boiling in constructal tree-shaped minichannnel possesses less pressure drop, lower pumping power requirement, better temperature uniformity and higher thermal efficiency. The pumping power requirement in the constructal tree-shaped minichannel is about half of the corresponding serpentine channel's, and the thermal efficiency is 1.9 times of that in serpentine channel with wall heat flux of 20 W/cm2.
