The exchanger is performing at its best when the outlet temperatures are equal. Counterflow heat exchangers are inherently more efficient than parallel-flow heat exchangers because they create a more uniform temperature difference between the fluids over the entire length of the fluid path.

Counter-current flow heat exchanger is a type of heat exchanger in which the two fluids flow in opposite directions. In this type of heat exchanger, the temperature difference between the two fluids decreases continuously along the length of the exchanger. The logarithmic temperature difference (LMTD) is a measure of the temperature difference between the two fluids in the heat exchanger.
The LMTD is defined as the logarithmic average of the temperature difference between the hot and cold fluids at any point along the length of the heat exchanger. The LMTD is an important parameter that determines the heat transfer rate in the heat exchanger.
In a counter-current flow heat exchanger, the LMTD between the two fluids is greater as compared to the parallel flow heat exchanger. This is because in a counter-current flow heat exchanger, the hot and cold fluids are flowing in opposite directions, which results in a greater temperature difference between the two fluids at any point along the length of the exchanger.
The greater temperature difference between the two fluids in a counter-current flow heat exchanger results in a higher heat transfer rate. This is because the temperature gradient between the two fluids is higher, which promotes a higher rate of heat transfer.
Therefore, in a counter-current flow heat exchanger, the LMTD between the two fluids is greater as compared to the parallel flow heat exchanger, which results in a higher heat transfer rate.
