| Abstract: | Experimentally studied was the heat exchange performance of a T-shaped fin inner-threaded boiling intensified heat exchange pipe with the refrigerating agent R134a serving as the working medium outside the pipe and water as the working medium inside the pipe.During the test,a series of data were obtained at a constant heat flux density(q=9 000 W/m2) and a constant water flow speed(v=1.5 m/s,v=2.6 m/s).By employing the Wilson diagram method,the authors have obtained the heat exchange coefficients inside and ... |
