A plate heat exchanger functions as a specialized device for transferring thermal energy between two fluid streams using a series of metal plates. One of its primary advantages over traditional heat exchangers lies in the substantial increase in surface area for heat exchange, achieved by spreading the fluids across these plates. This design greatly enhances the efficiency of heat transfer, resulting in a rapid temperature change.
Plate heat exchangers have become increasingly prevalent, even finding applications in compact, brazed versions within the hot-water systems of countless combination boilers. The remarkable heat transfer efficiency, despite their compact size, has notably boosted the flow rate of domestic hot water in such boilers. While larger commercial variants employ gaskets to seal the spaces between plates, smaller versions are typically brazed together
