Serrated Spiral Tube Boiler Fin Tube Radiator Efficient Heat Transfer Performance
Serrated Spiral Fin Tube Description
Serrated spiral fin tube radiator is a heating system in the main heat dissipation device, it mainly uses low temperature medium, through the heat source will be heated into a high temperature medium, through a certain way to its input pipe, and then through the pipeline transmission to the installed radiator indoor, indoor heating effect
High temperature heat medium of serrated spiral finned tube radiator after circulating and dissipating heat, its temperature will reduce and become a medium of low temperature, which is the medium of low temperature will flow back through the radiator reflux pipe, and then through the heat source heating into high temperature heat medium, so as to cycle again, this is the simple working principle of the radiator system.
Serrated spiral finned tube is a special-shaped extended surface developed on the basis of spiral finned tube. Its manufacturing process is similar to that of high-frequency welded spiral finned tube, but the difference is that the gap of the strip must be cut before winding the serrated spiral finned tube.When winding, the cut part is separated naturally, forming a gear shape.On high frequency welding spiral fin hobbing winding technology not only simplifies greatly reduced (deformation), has combined with tight, high strength, thermal shock and mechanical shock, thermal performance is good, small flow loss, strong corrosion resistance performance, and has considerable diffusion surface, in cold and hot condition for a long time is not easy to deformation, long working life, also because of the destruction of flow boundary layer and intensified heat transfer.This serrated fin has been widely used in air conditioners and boiler economizers.
Compact space and low cost
The pipe set is much compact and reduces the height of tail smoke well.
The total weight is greatly reduced and the load of the suspension system is reduced.
Reduce cost of economizer and integral boiler.
Reduce smoke lateral resistance
Reduce the operating and investment cost of induced fan.
