According to the experimental results, first of all, the critical heat flux will increase with the increasing of mass flux rate; Moreover, we found that the scale-shaped surface with tip angle of 45 °can get the highest critical heat flux; last, the experimental results showed that the scale-shaped surface with reverse arrangement have higher critical heat flux compared to the the scale-shaped surface with forward arrangement.
