A new type of three-dimensional inner microfin tube is used in the present paper. And the two-phase closed thermalsyphon is made in such kind of tubes with two geometries, called T1 and T2 tube respectively. The refrigerant used in this heat transfer performance experiment of heat pipe is water and methanol.
The experimental conditions are as follows: the heat flux is from 5 kw/m2 to 32 kw/m2, the working temperatures are between 40℃ and 95℃, the liquid full ratio is from 20%~40%, an...
