@Yasin consider the following.
1. Hot fluid enters from left.
2. Cold fluid enters from the right.
(since it is counter flow HE both fluids will enter in opposite direction i.e. left and right respectively.
3. Hot fluid will become cold and leaves from the outlet.
4. Cold fluid gets hotter and leaves from left.
Now consider 1 & 4, both fluids at the inlet are hot.
1. Hot fluid enters from left.
2. Cold fluid enters from the right.
(since it is counter flow HE both fluids will enter in opposite direction i.e. left and right respectively.
3. Hot fluid will become cold and leaves from the outlet.
4. Cold fluid gets hotter and leaves from left.
Now consider 1 & 4, both fluids at the inlet are hot.
