A heat exchanger is device which heat exchangers among two or more fluids. Heat exchanger are using for the heating and cooling systems in domestic and industrial operations. When heat exchanger devices are used in any operation than some heat losses in atmosphere. We studied different research paper and analysed the performance parameter of heat exchangers. After studied of different research paper, I found new idea to get better the thermal performances of counter to cross flow by using air cooled heat exchanger [ACHE] process. Constrained geometry structures are counter to cross flow using air cooled heat exchangers process. In air cooled heat exchanger [ACHE] process is using internal grooved aluminium concentric tube and aluminium fins. Hot water will be flow in spiral grooved aluminium tube and rectangular fins will be fitted on tube. A fan will be fitted perpendicular to the tube which expand cold air through the fan on tube. In this study, time-domain simulations are performed for the National Advisory Committee for Aeronautics Air foil 6512 propeller. NACA 0015 was used for blade inner fan with a variety of inner fan blade angles 150, 300, 450 and 600 and varied wind speed to turbine ventilator 1.5, 3, 4.5 and 6 m/s. The fans will blow the air on tube due to hot fluid will be decreases the temperature outlet of tube. We will be temperature difference found input and output of the hot fluid.
