Powerful than plate and shell in shell and tube coil, because the plate plate plate that has the appearance of having high thermal conductivity, heat transfer can be received through a sheet of plate. Although there is no touching between the hot and cold water, heat, which can also be applied to heat exchanger, all 3 types, there is an area in the same heat exchange and therefore does not affect the trial. But it will depend on the characteristics of the heat exchanger and the flow rate when the flow rate of hot water flow rate is constant, then add cold water up to the heat exchange rate decreased.
