Double-pipe Heat Exchanger

Objective

From production of the ink in your ball-point pen, to the hydraulic brake fluids of your car - ethylene glycol finds itself in a wide variety of industrial applications. Controlled heating of ethylene glycol is, therefore, of significant interest in the industry. One way to do this is to use a Double-pipe Heat Exchanger (DPHX).

In our project, we designed and fabricated a prototype counter-flow double-pipe heat exchanger, to be used in water-controlled heating of ethylene glycol. Moreover, we optimized the pipe dimensions to achieve the required heat transfer using minimal build materials, thus minimizing material costs.
