Seek a design for a cooler

Task requirement: Use circulating cooling water as the cooling medium; the pressure of this circulating cooling water is 0.3 Mpa, with an inlet temperature of 32 degrees and an outlet temperature of 37.5 degrees. It is necessary to cool air with a flow rate of 23,000 cubic meters per hour from 80 degrees to 35 degrees, at a pressure of 0.6 Mpa; a cooler needs to be designed to accomplish this task. I want to design a shell-and-tube heat exchanger based on this design... But I haven’t mastered the concepts related to heat exchange, QAQ. So I have to turn to everyone here for help. Thank you so much. :'(
A basic design at the undergraduate level... I’m asking for help here; I’d like to know how to approach designing this I should 1) estimate the heat transfer area based on the requirements, and then determine the tube side and shell side -> 2) calculate the heat load -> so what should I do next?
Find a calculation software for heat exchangers and do the calculations yourself.
Take a look at this~~~https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1308694&extra=
Water outlet 37: You want it to reach 35 degrees – the temperature difference is very small. The heat exchanger will have to be quite large in size
