Nov 1, 2001 · In this study, a highly efficient shell-and-tube heat exchanger with spiral baffle plates is simulated three-dimensionally using a commercial thermal-fluid analysis code, CFX4.2. In this...

plates is superior to the conventional heat exchanger in terms of heat transfer. Key Words: Shell-and-TubeHeat Exchanger, Conventional Vertical Baffie Plate, Spiral Baffie Plate,...

Nexson spiral heat exchangers are used for a design pressure from full vacuum to 80 barg and at -200°C design temperature to 450°C. Nexson Group supplies a wide range of spiral heat exchangers from customized to standard units.

The purpose that realizes the spiral baffle heat exchanger shell-side round trip type of flow is under the equal volume flow, can improve the flow velocity of shell fluid and under limited...

Large cross-section circuit for high flows and/or high viscous fluids. Small cross-section circuit for low flows and/or lower viscous fluids. All standard connections are tapered pipe thread. Refer to model data for connection size. Pipe the heat exchanger for counterflow fluid direction.

Jan 1, 2025 · Cao et al [23], [24] investigated the HTC and flow property of spiral baffle heat exchanger by numerical simulation and experimental analysis, comprehensively considered the spiral angle and the axial superposition ratio of the spiral baffle structure, and proposed an optimal design method on the basis of the multi-objective optimization ...

The invention provides a process for manufacturing a spiral baffle plate of a shell-and-tube heat exchanger.

In this study, a highly efficient shell-and-tube heat exchanger with spiral baffle plates is simulated three-dimensionally using a commercial thermal-fluid analysis code, CFX4.2. In this type of heat exchanger, fluid contacts with tubes flowing rotationally in the shell.

Dec 28, 2015 · The idea that the spiral baffle plate heat exchanger is based on the idea that the fluid in the shell side of the shell side is in a continuous spiral flow by changing the layout of the shell side baffle plate. Therefore, the ideal baffle plate should be arranged as …

The arch and disc-ring baffle plate is the most commonly used baffle plate in a shell-and-tube heat exchanger, has simple forming and easy opening, but is gradually replaced by a spiral...
