In counter flow heat exchangers
WebCounter flow heat exchangers are the most efficient of the three types. In contrast to the parallel flow heat exchanger, the counter flow heat exchanger can have the hottest cold … Webremains nearly constant (Fig. 3(b)). Counter flow heat exchangers provide the maximum heat transfer rate for a given surface area. Hence, they are the most widely used heat exchangers. 2 L (Length) Fig. 3 Counter Flow Heat Exchanger Temperature difference(θ 1) = t h 1 −t c 2 … (4) Temperature difference(θ 2) = t h 2 −t c 1 … (5)
