The graph shows the relationship between the efficiency of heat transfer with the angle of incline angle adjustment case, CNN, Thermo tube 90o substance R134a 300 mm working length, when evaporation temperature is. more contribution will result in heat transfer efficiency is high, but when the temperature contribution less volatile substance makes the work less and in part of a work, performance, better heat transfer is working the corners 0-150o afterward, heat transfer performance reduced the working angle 170-180o.
