Full Welded Plate Heat Exchanger Evaporator Water Cooler Plate And Shell Heat Exchanger

Fully Welded Plate Heat Exchanger is a plate heat exchanger made of a series of corrugated metal plates welded by laser or argon arc welding. The plate group and the plate group are connected by welding with molding strips. Because there is no gasket seal, it has higher temperature and pressure resistance. It can be applied to extreme working conditions of high temperature and high pressure.

Plates
Plates can be produced in a wide range of materials. After pressing and cutting, the plates are welded together to form a fully welded platepack. Nozzles are added which carry flow in and out of the platepack (the 'Plate side' flowpath).

Shells
The fully welded platepack is assembled into an outer shell which creates a second flowpath ( the 'Shell side'). The different types of shell arrangements and the normal flow patterns are shown below.
Shell and plate type heat exchanger is composed of round plate bundle and shell, plate bundle is the core, sealed in shell. Plate defines the efficiency of PHE, while shell defines the design temperature and pressure.
The medium pass through the port holes and into the gap between the plates. The heat transfer takes place when the warmer product transfers energy through the flow plates and delivers it to the colder opposing medium without mixing the both products.
