Stainless steel tube coil heat exchanger,low pressure drop,good heat exchanging

Customize Stainless steel tube coil heat exchanger, Stainless steel tubing heat exchanger.Materials can be stainless steel pipe,or copper pipe.Coil heat exchanger typically consists of a stainless steel or copper or titanium tube which is bent as needed into a desired shape and size, such as circular, rectangle, spiral, and long serpentine. It was the first appearance of heat transfer equipment with a simple structure and easy operation. The main advantage is the ability to flow liquid, steam, or refrigerant with a small pressure. It has very high heat exchange efficiency, no leakage, and can withstand high pressure.If process with advanced technology, they can be got with excellent corrosion resistance to a wide range of chemicals, salts, and acids.

The coil heat exchangers are always used in the fields of food, industrial, HVAC, and architectural and transportation fields,it is also called tube serpentine heat exchangers.

Advantage :

√ The heat exchanger is made from seamless SS tube grade 304,316,316L,seamless ,and the tube can stand high pressure.Also can be made from copper or titanium tubing.
√ Our equipment machine can help you to fabricate any grade stainless steel tube into any the designed shape and required dimension.
√ If you need,we can process the tube surface with

polished technology .
√ The coil reached food grade standards.
√ Smooth inner surface and the refrigerant or water can circulate flowing in the coil,small pressure-drop.
√ The material has good performance of resistant to corrosion.
√ Customizable size as you required.

Stainless Steel has good heat conductivity performance and properties .It is also healthy,and no problem to contact water or food directly.

Therefore,Stainless steel tube coil heat exchanger  is used to transfer heat in a wide variety operating conditions. coil immersion heat exchanger is more efficient than shell and tube exchangers for low flow rates. Due to their simple construction they are low in price and convenient to clean on the shell side. Thermal efficiency approximates that a true countercurrent flow type exchanger. Condenserors are used for condensation vapours cooling liquids. Condensers are made by fusing number parallel coils in a glass shell. Stainless steel  tube coil immersion heat exchanger is artificial to special requirements as to dimensional tolerances, finish and tempers for use in condensers and heat exchangers. Copper heat exchanger tubes are normally supplied in straight length in annealed half hard temper. It is not only have the stiff tolerances the most dependable dimensions throughout the tube length. The tube surface is clean both inside. Coils are made in different diameters using tubes different bores.

Calculation of heat transfer area of stainless steel coil：

Heat transfer area calculation formula: F=Q/KK*△tm

F is the effective heat transfer area of the coil heat exchanger device; Q is the total heat transfer heat; k is the dirt coefficient, which generally takes 0.8-0.9; K is the heat transfer coefficient; △tm is the average temperature difference.

Setting: The specific heat of air d[j/(kg*k)], density p(kg/m³), tube thickness h(m), and the thermal conductivity of stainless steel λ[j/(m*k)]. The required heat dissipation area is S(㎡).

Average temperature difference ΔT=(82+33)/2-29=28． 5(k)
