Copper Special Tube
- High Finned Tube
- Inner Ridged Tube
- (is called Inner Grooved Tube or Inner Finned Tube) is an internally grooved tube designed primarily for direct expansion water chillers. Direct water chillers are used for air conditioning applications wherein water is cooled on the outside of the tube by refrigerant boiling and expanding on the inside.
Inner Ridged Tube is normally supplied in straight lengths and draw temper for easy insertion into the tube bundles.
Inner Ridged Tube has 1.5 to 2 times the average inside heat transfer coefficient of the same plain tube.
Plain end is manufactured as the requirement of customers.
- Spiral Tube
- This is manufactured by twisting a plain tube; it has a deep and sharp spiral wavy structure so that is has higher heat transfer characteristics than the corrugated tube. It has high flexibility so can be used in coils.
- Low Finned Tube
- Low Finned Tube is manufactured by crosshelical rolling continuously from plain tube.
The finned tubes are widely used as heat transfer tubes because of their large external surface area and high heat transfer performance compared with a plain tube.
The fins and tube are completely integrated, so the heat transfer performance, durability and resistance to vibrations are excellent. The treatment of the tube ends and the land can be chosen to suit the application.
The equipment can be made compact because the heat transfer area is larger than that of a plain tube.
The annealed finned tubes can easily be bent and processed.
- Corrugated Tube
- The corrugated tube was developed to use in water chillers. Water chillers are used for air conditioning applications where water is cooled on the outside of the tube by a refrigerant boiling and expanding on the inside.
Under proper conditions, corrugated tube can provide superior heat transfer performance and less tubeside pressure drop than ordinary plain tubes with ID turbulence devices. The integral corrugations are produced without thinning the wall, and the minimum wall of the starting tube is uniform for the entire lenght of tube. Also, the OD of the corrugated section is the same as the plain end OD.
- Turbo-E Tube
- Turbo-E Tube is a revolutionary heat transfer tube for boiling on outer surface.
It has very excellent heat transfer coefficient derived form an unique fine structure based on the boiling phenomenon essentially; it is different from the conventional integral fin tube which simply increase the surface area.
- Flower Tube
- Flower Tube is used for heat exchanger of absorption refrigerating machine and heat pump.
It's low price against high quality coefficient, and could be increase 30% refrigerating effects through using multiqlicity of cavities tube and adding surfactant.
Figure shows comparative cooling performance ability of plain tube, finned tube and flower tube.
It be seen flower tube is superior to others.
