What is fully welded plate and frame heat exchanger?
The fully welded plate and frame heat exchanger is a new concept in heat transfer technology. It combines the advantages of both gasket and frame plate heat exchangers and shell and tube heat exchangers. It offers efficient heat transfer and a compact construction like a plate heat exchanger, while also being suitable for high temperature and pressure applications like a shell and tube heat exchanger.
With its internal countercurrent flow design, the fully welded plate and frame heat exchanger can achieve a terminal temperature difference that cannot be met by other fully welded heat exchangers. Additionally, its cover board can be easily opened for cleaning purposes.
One of the key features of this heat exchanger is the high liquid shear stress that occurs in the passage, which is higher compared to other welded plate heat exchangers. This enhances heat transfer efficiency. Furthermore, the fully-welded plate and frame heat exchanger have a special flow design that allows it to be used as an efficient condenser.
Welded Plate Heat Exchangers for Industry Applications
- The fully welded plate heat exchanger is commonly used in the chemical industry for applications such as heating or cooling corrosive fluids, condensing or evaporating solvents, and recovering heat from chemical processes. Its corrosion-resistant materials and compact design make it suitable for handling aggressive chemicals.
- In the oil and gas industry, the fully welded plate heat exchanger is utilized for applications such as oil cooling, gas processing, and heat recovery from refinery processes. Its high thermal efficiency, compact size, and ability to handle high temperatures and pressures make it ideal for these demanding conditions.
- The welded plate and frame heat exchangers are employed in power plants for various heat transfer tasks. They are used for cooling turbine oil, condensing steam, and heating or cooling feedwater. Their compact design and high heat transfer efficiency contribute to improved energy efficiency and reduced operating costs.
- The fully welded plate heat exchanger finds applications in the food and beverage industry for processes such as pasteurization, sterilization, and cooling of food and beverage products. Its hygienic design, easy cleaning, and high heat transfer efficiency ensure product safety and quality.
- Fully welded plate heat exchangers are used in heating, ventilation, and air conditioning (HVAC) systems for heat transfer between hot and cold water streams. Their compact size, high thermal efficiency, and ability to handle varying load conditions make them suitable for HVAC applications.
Advantage of Fully Welded Plate and Frame Heat Exchanger
- Compact and space-saving design. WPHE occupies less floor space compared to traditional shell and tube heat exchangers.
- Provide efficient heat transfer due to its large surface area and turbulent flow created by the pattern of welded plates. This results in improved thermal performance and reduced energy consumption.
- Constructed using corrosion-resistant materials such as stainless steel or titanium. This makes it ideal for handling corrosive fluids and environments, ensuring long-term durability and reliability.
- Understand high temperatures and pressures, making it suitable for applications that require heat transfer in extreme operating conditions.
- Designed for easy maintenance and cleaning. The plates can be easily accessed and cleaned, reducing downtime and ensuring optimal performance.
