FAQ

How do LMTD and NTU methods differ?

Use LMTD when outlet temperatures are known or easy to estimate. Use NTU-effectiveness when outlet temperatures are unknown and you want to predict exchanger performance.

Are heat-sink and fin calculations the same?

Heat-sink design includes fin efficiency, but also base resistance, contact resistance, airflow, and allowable temperature rise.

Why separate heat exchanger hubs for SEO and usability?

Grouping exchanger, fin, and cooling tools separately from broad HVAC pages makes the specialist cluster clearer for users and search engines.
