Product Overview

The Fully Welded Plate Heat Exchanger is a highly efficient and compact heat exchange device that achieves heat transfer between two media through channels formed by corrugated plates. The equipment uses high-quality stainless steel or titanium alloy plates, featuring high heat transfer coefficient, small footprint, light weight, and easy disassembly and cleaning. It is widely used in heating, refrigeration, chemical, food, and pharmaceutical industries.

Working Principle

The Fully Welded Plate Heat Exchanger consists of alternating corrugated plates that form narrow channels between adjacent plates. Two fluids (hot and cold) flow on opposite sides of the same plate, transferring heat through the metal plate. The corrugated plate design creates turbulence at low flow rates, significantly improving heat transfer efficiency while reducing the risk of fouling.

Technical Features

Heat transfer coefficient up to 3000-7000 W/(m²·K), 3-5 times that of shell-and-tube heat exchangers
Compact structure, footprint only 1/5-1/3 of shell-and-tube heat exchangers
Plates formed by stamping, uniform channels, balanced pressure distribution
Flexible adjustment of heat exchange area by adding or removing plates
Easy disassembly and cleaning, low maintenance cost
Low metal consumption, excellent cost-performance ratio

Applications

The Fully Welded Plate Heat Exchanger is suitable for various industrial and civil applications:

Heat exchange stations in central heating systems
Evaporators and condensers in air conditioning systems
Heating, cooling, and condensation processes in chemical industry
Sterilization and temperature control in food and beverage industry
Waste heat recovery in metallurgy and power industries
Cooling systems for ships and offshore platforms

Selection Guide

When selecting the Fully Welded Plate Heat Exchanger, consider the following factors: heat transfer medium properties (corrosiveness, viscosity, cleanliness), operating temperature and pressure range, flow requirements, and installation space limitations. It is recommended to choose appropriate plate material (316L stainless steel, titanium, Hastelloy) and gasket material (NBR, EPDM, FKM) based on actual working conditions.
