Apr 23, 2020 · Within the class of compact heat exchanger, the sub-class of high efficiency CHEs is generally characterized by high film coefficients and low fouling factors that both contribute to higher overall U values. While these attributes alone tend to make the CHEs smaller in size than conventional shell-and-tube and other longitudinal heat exchangers, the use of close channel spacings also allows
inside of a countercurrent, double-pipe heat exchanger at 300K and is heated by an oil stream that enters at 385K at a rate of 3.2kg/s. The heat capacity of the oil is 1.89 kJ/kg K, and the average heat capacity of water over the temperature range of interest is 4.192 kJ/kg K. The overall heat-transfer coefficient of the exchanger is
Heat Exchangers IPIECAHeat exchangers can improve a systems energy efficiency by transferring heat from systems where it is not needed to other systems where it can be usefully used. For example, waste heat in the exhaust of an electricity-generating gas turbine can be transferred via a heat exchanger to boil water to drive a steam turbine to generate more electricity (this is the basis for Combined Cycle Gas Turbine technology).
Sep 29, 2017 · CompRexs proprietary compact technology not only increases heat exchange efficiency by at least 25 % but also reduces footprint by at least a factor of ten compared to traditional shell-and-tube solutions of the same capacity and by 15 to 20 % compared to other currently available Printed Circuit Heat Exchanger (PCHE) solutions.
