3

 Design and manufacture a heat exchanger learning apparatus to provide students with a comprehensive study of heat exchangers and the various parameters that effect their performance. 4

5

 Heat exchangers are devices that provide the flow of thermal energy between two or more fluids at different temperatures.  Functions Heat a cooler fluid by means of a hotter fluid. Reduce the temperature of a hot fluid by means of a cooler fluid. 6

7

 Heat exchangers are used in a wide variety of applications Transportation Electronics Household National Defense Industry Energy Farm & Fishery Environmental Engineering 8

9

 Most educational institutions that offer engineering courses in thermodynamics and who specialize in heat exchangers are only capable of teaching their students the theoretical knowledge.  They do not have the necessary equipment to educate them on the various parameters that effect heat exchangers. 10

 The reason that most educational institutions can’t afford to purchase this type of equipment is because of the financial situation  Due to the recession most educational institutions are being subjected to budget cuts 11
