The brazed Plate Heat Exchanger (BPHE) is a type of heat exchanger construction in which metal plates with flat surface offer an effective and efficient method of heat transfer. These plates are joined together by brazing (mainly copper), typically stainless steel. Due to the close contact between the two surfaces, there is a very high heat transfer coefficient, leading to a low overall unit size. They therefore provide much greater efficiency than a Shell And Tube Heat Exchanger.
Brazed Plate Heat Exchangers are widely used in air-conditioning and refrigeration, power generation, and other process applications. For example, within a cooling cycle, a BPHE can be used to transfer heat from one fluid to another. Typical fluids in such coils and systems are either glycol or water. In a power system, a BPHE can be used to cool oils, recirculating lubricants, fuels, and other fluids.
The major advantages of BPHE are their compact size, efficient heat transfer and minimal pressure loss. BPHEs also have low maintenance requirements and a long service lifetime. Furthermore, because of their flat surface design, BPHEs have no patterns or turns and thus lower energy costs and minimize fouling. Finally, the material used in BPHEs makes them resist to corrosion and heat, making them ideal for high temperature and hostile environments.
