DESIGN, MANUFACTURING AND TESTING OF SHELL AND TUBE HEAT EXCHANGER AND TO COMPARE THE PERFORMANCE USING PLAIN TUBES AND LOWFIN TUBES

Abstract

The project aim is to provide an overview of design, manufacture and testing of shell and tube heat exchanger and to compare the performance with using plain tube and low fin tubes. The objective of the project is to remove the heat from the lubricating oil passing it through the heat exchanger where in a coolant is circulated to remove the heat. Water is commonly used as the coolant to dissipate heat. The heat exchangers are designed for shell side flow rate 35lpm, temperature 55 o C-45 o C and tube side flow rate of 30 o C-35 o C. First the design calculations are done using the details of heat exchanger, various correlations and finally arriving at the design drawing of heat exchanger using the AutoCAD tool. Various manufacturing techniques were used for manufacturing of heat exchanger. Testing was then done on the manufactured heat exchangers for checking the performance of the heat exchangers.
