Detailed Introduction: Square Fully Welded Plate Heat Exchanger
The Square Fully Welded Plate Heat Exchanger is a versatile thermal transfer device with the following core features:
Structural Features
Welded Shell:The main body typically consists of two parallel square or rectangular shells, housing multiple sets of parallel tube bundles or plates to achieve heat transfer. This structural design ensures the exchanger is highly compact, effectively saving installation space.
Corrugated Plate Structure:Adjacent plates are welded together to form independent flow channels. The plates often feature chevron (herringbone) or other corrugated patterns. This design enhances fluid turbulence, thereby improving heat transfer efficiency.
Convenient Detachable & Washable Design:The shell of some models adopts a six-sided detachable structure. When plate blockages occur, the surrounding cover plates can be directly removed for cleaning operations, compatible with both mechanical and chemical cleaning processes.
Core Performance Advantages
Excellent High Temperature & Pressure Resistance:The fully welded structure completely overcomes the limitations of gasket sealing. It can withstand high-pressure conditions (typically ≥
4.0 MPa) and temperatures up to
800°C, making it suitable for various harsh industrial operating environments.
Outstanding Heat Transfer Efficiency:The corrugated plate design induces high-intensity turbulence within the flow channels, with a heat transfer coefficient
3 to 5 times that of shell-and-tube exchangers. While maintaining equivalent thermal exchange capacity, the equipment volume can be reduced by
30%-50%.
Strong Corrosion Resistance:The all-metal welded structure fundamentally eliminates the issue of rubber gasket aging. Furthermore, special materials such as
Hastelloy and
254SMO can be selected based on medium characteristics to easily handle corrosive environments like acids and high-salt conditions.
Economical Maintenance Costs:The gasket-free design eliminates leakage risks, and the integral welded structure reduces the risk of vibration damage. This results in a longer maintenance cycle and superior lifecycle cost advantages.
Flexible Flow Channel Configuration:Supports various flow channel designs, including single/multi-pass and symmetric/asymmetric configurations. It can adapt to different flow rate ratios and temperature difference requirements, with a flow rate ratio adjustment range covering
1:1 to 6:1.
Key Technical Parameters
Flow Rate Range: Standard applicable flow rate is 1-2000 m³/h.
Working Pressure: Adaptable to pressure ranges from vacuum to 8.2 MPa.
Operating Temperature: Standard applicable temperature range is -195°C to 300°C.
Connection Specifications: Interface sizes range from DN25 to DN300, supporting various connection methods such as welding, flange, and threaded connections.
Applicable Application Fields
Widely used in industries such as chemical, petroleum, food processing, and power generation. It can perform cooling or heating operations for different media including liquids, gases, and steam, fully meeting the thermal exchange needs of various process applications.
