Heat transfer is the core function of a heat exchanger. The laws of thermodynamics provide the basic rules for heat-exchanger design:
1st Law of Thermodynamics: A heat exchanger cannot destroy or create energy, but there is always a balance between the hot and cold sides.
2nd Law of Thermodynamics: Heat flows from a hot medium to a cold medium to equalise the temperature difference.
Heat transfer is the exchange of heat between hot and cold bodies. There are three fundamental modes by which this occurs:
- Conduction
- Radiation
- Convection
Heat transfer in a heat exchanger is a combination of conduction and convection. Conduction and convection are calculated in each heat-transfer case.
Calculating heat transfer
The total heat-transfer coefficient U is calculated by the sum of the convective heat transfer from both sides (hhot and hcold) of the heat-transfer surface and conduction (k) through the heat-transfer plate.
