Alfa Laval spiral heat exchangers (SHEs) are based on an ingen-ious design. It provides optimum heat transfer and flow conditions for a wide variety of fluids, with a built-in self-cleaning effect, while keeping the overall size of the unit to a minimum. Above:Welded single-channel geometry eliminates the risk of intermixing of the two fluids.
The experimental setup was designed essentiallyto investigate the forced convection heat transfer in a spiral plate heat exchanger. The setup was fabricated in Sehore, and erected in the Mechanical Engineering Department at Faculty of Technology & Engineering, RGPV Bhopal. The schematic diagram of the heat exchanger test loop used for the study is as shown. Water, the working fluid, is drawn
Spiral heat exchanger technologyAug 01, 2021 · An SPHE consists of a shell and plates (which are welded to the shell) in a spiral shape that are separated by spacing studs to accommodate both hot and cold fluids in a countercurrent flow. This inherent design feature of an SPHE results in a compact design and enables cleaning of the internals by a hydro-jetting process and chemical cleaning.
