Efficient plate heat exchanger plate heat exchanger is a high efficiency, compact structure, easy maintenance of heat transfer equipment, has been widely used in heating, air conditioning, water supply and drainage, metallurgy, chemicals, video, petroleum, machinery and other industries, become the designer of choice for users and the plate heat exchanger, BR series plate heat exchanger consists of a pack of corrugated metal plates and gaskets, compression plate, guide bar, column, and took over the clamp bolt and other components. The four corners of the board opened a corner plate heat exchanger consists of a pack of corrugated metal plates and gaskets, compression plate, guide bar, column, and took over the clamp bolt and other components. Angular corners of the board open holes for the two heat transfer fluid passes. Metal plate mounted within the frame fixed plate and movable pressing plate composed, with the clamping bolt intensify. Board equipped with gaskets, seals the fluid passage, and alternately directing the fluid flow into the respective channels. Corrugated board not only improves the degree of turbulence, and forming a plurality of support points, the media enough to withstand the pressure difference.
