Product Description

Plate heat exchanger is an ideal equipment for heat exchange between liquid and steam. The utility model has the advantages of high heat exchange efficiency, small heat loss, compact and light structure, small floor area, wide application, long service life, etc. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, the floor area is one third of the tube heat exchanger, and the heat recovery rate can be as high as 90%.

As the gasketed plate heat exchanger became apparent that a gasketed design restricted plate technology in many industrial processes. To satify this demand, a wide range of welded plate heat exchanger designs were developed to meet different process requirements. Welded plate heat exchangers use the same principles as their gasketed counterpart but employ a fusion weld to seal the fluid flow channel instead of the gasket. The result is a fully welded heat transfer plate pack.

1. Core Structure

•   Composed of multiple metal plates welded by laser, plasma or argon arc welding.

•   The plates are pressed into corrugations to form dense flow channels.

•   Divided into two independent flow systems that are completely isolated from each other.

•   No rubber gaskets, suitable for high-temperature, high-pressure and strong corrosion working conditions.

• 
  

2. Working Process

•   Two fluids (hot fluid and cold fluid) enter different channels respectively.

•   The fluid flows at high speed in the narrow corrugated channels, forming strong turbulence.

•   Heat is transferred from the hot side to the cold side through the thin metal plates.

•   The fluids do not mix or leak; only heat exchange occurs.

•   The outlet provides the cooled hot fluid and the heated cold fluid separately.
