In counter flow heat exchangers
WebA cocurrent heat exchanger is an example of a cocurrent flow exchange mechanism. Two tubes have a liquid flowing in the same direction. One starts off hot at 60 °C, the second cold at 20 °C. A thermoconductive membrane or an open section allows heat transfer between the … WebIn a counter flow cooling, the incoming cooling medium absorbs heat as the ‘hot’ fluid travels in the opposite direction. The cooling medium heats up as it travels through the …
