Abstract (2. Language):
The present paper investigates the fundamental thermodynamic laws and heat exchanger tank. It introduces the entropy and examines the second law of thermodynamic analysis for this type of exchanger. The methodology involves examining heat exchanger tank under different laboratory conditions including the power of heat element inside the tank, mass flow rate of cooling water of tank wall and the mixer speed inside the tank as variables. The data for the water temperature inside the tank and output water were obtained after cooling the tank wall. The entropy generation rate was then drawn and the optimal performance criteria of the heat exchanger tank and its optimal range were evaluated by minimization of entropy via the second law analysis. This was undertaken to increase the efficiency and decrease energy consumption. The results indicate that when the mass flow rate of input cold water, power of heat element and the mixer speed were respectively controlled in their possible minimum measures, the system tend to perform in optimal conditions according to the second law of thermodynamics.
