Spiral-tube heat exchangers consist of one or more spirally wound coils which are, in circular pattern, connected to header from which fluid is flowed. This spiral coil is installed in a shell another fluid is circulated around outside of the tube, leads to transfer the heat between the two fluids.
Spiral Wound Pipe Heat Exchanger:working principle:Compared to traditional parallel bundle,the bundle of Wintech arranged by helix in shell,this configuration prolong the tube in shell, sufficient the exchange; Change liquid state and enhance turbulence effect,enhance the exchange coefficient. And this design could eliminate the shake and stress.
Investigation on the thermal performance of spiral wound Apr 01, 2021 · Spiral wound heat exchanger has compact structure, good thermal performance per volume and simple manufacture process. It is the key equipment for the superfluid helium cryogenic system, which is able to recover the cold capacity and improve the refrigeration effectiveness.
The core of our spiral heat exchangers is the concentric spiral plate coils nested in the shell. The coils form two completely separated channels with a countercurrent flow arrangement that allows the heat exchanger to achieve very close temperature approaches, making our spiral units excellent for heat recovery applications.
The spiral heat exchanger - a higher overall heat transfer
Process calculation method and optimization of the spiral Apr 01, 2018 · Spiral-wound heat exchangers (SWHEs) is a special compact shell and tube heat exchangers, whose unit volume has a large heat transfer area, about 100170m2.
Jul 07, 2016 · Spiral heat exchangers are devices which are highly efficient in extremely dirty and fouling process duties. Spirals inherent in design maintain high heat transfer coefficients while avoiding hazardous effects of fouling and uneven fluid distribution in the channels. Heat pipes
Alfa Laval spiral heat exchangersAlfa 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.
