How does a plate heat exchanger work?
Heat transfer theory
The law of physics always allows the driving energy in a system to flow until equilibrium. Heat dissipates when there is a temperature difference.
A heat exchanger follows the equalisation principle. With a plate heat exchanger, heat cuts through the surface and separates the hot medium from the cold. Thus, heating and cooling fluids and gases use minimal energy levels.
The theory of heat transfer between mediums and fluids happens when:
- Heat is always transferred from a hot medium to a cold medium.
- There must always be a temperature difference between the mediums.
- The heat lost from the hot medium is equal to the amount of heat gained by the cold medium.
