Copper nickel heat exchanger tube
There is a difference between copper-nickel heat exchanger tubes and copper-nickel condenser tubes.
The design of copper-nickel heat exchanger tubes allows for heat transmission from fluids that have a high temperature to one that has a lower temperature.
This happens without there being a phase change.
The design of a copper-nickel condenser allows for the conversion of a fluid from one state to another.
That is, from gas to liquid.
The outlet of a copper-nickel condenser tube is larger than that of the inlet.
This is to allow for a smooth flow of fluid after conversion from gas to liquid while maintaining the same pressure.
The inlet and outlet are of the same size when it comes to a copper-nickel heat exchanger tube.
Besides, this is because only heat is transferred from one fluid to another, and there is no change in its form.
Why Choose Copper Nickel Tubes for Heat Exchanger Systems?
Selecting copper-nickel tubes for use in your heat exchanger system is ideal because of:
- Efficient heat transmission
- Ease of dismantling
- Relatively cheap compared to other heat exchangers
How do you Install Copper Nickel Heat Exchanger?
Copper nickel heat exchanger system
Copper-nickel heat exchanger installation can either be vertical or horizontal, depending on the type. However, you need to check on the inlet and outlet positions.
That is, you should position the oil outlet next to the water inlet. This facilitates the counter flow and helps in cooling and heating.
If it is in a horizontal position, you have to position a vent around the water outlet if it is facing upwards.
Ensure you support your tube work and try minimizing on using long tube lengths.
If you are installing in an application that experiences frequent vibration, you need to use flexible hoses. Alternatively, you can use a flexible compensator flange.
Installation of the cooler element of your copper-nickel heat exchanger should be around the return line of your tank.
But if there is a high fluctuation of pressure and temperature, you need to mount the cooler off-line, and it should have its re-circulation pump.
The positioning and functioning of the cooler should be in such a position that it cannot freeze.
In a cold environment, the use of a check valve is vital as it helps in bypassing oil.
You need to check on the type of water, its pressure, and temperature.
This helps in determining the flow level of the water as it cools or heats your system.
The temperature control valve should be in the water section.

the type of fluid affects the structure of the copper-nickel tubes and also the ease of it flowing through the heating system.
Gases and liquid have light materials and flow relatively smooth compared to semi-solid fluids.
· Expansion Rate
The rate of expansion of copper-nickel heat exchanger tubes determines the temperature of the fluid flowing through it.
Besides, the expansion rate helps in determining the operating pressure and temperature of a given fluid.
· Pressure Limits
Understanding the operating pressure limits of a given copper-nickel heat exchanger tube.
This prevents the bursting of the tubes during operation.
An ideal pressure limit for your copper-nickel heat exchange tube should be within that of the fluid that is flowing through it.
· Ease of Cleaning
Given the various types of fluids flowing through a copper-nickel heat exchanger tube, it is critical to check on its cleanability.
The structure of such a heat exchanger tube should allow for cleaning.
Besides, the cleaning agents should not react negatively with the heat exchanger tube.
· Pressure Drop
The pressure drop within the copper-nickel heat exchanger tube should be uniform for the uniform flow of the fluid.
This ensures there is even fluid flow through your application.
· Fluid Flow Capacity
Understanding the fluid flow capacity within a given copper-nickel heat exchanger tube prevents its rupture.
The fluid flow capacity should correspond to the pressure limits of a given copper-nickel heat exchanger tube.
How do you differentiate between Copper Nickel Tube and Copper Nickel Pipe?
The design of a copper-nickel pipe differs from that of a copper-nickel tube.
The standard specification of a copper-nickel pipe its cross-section is circular.
On the other hand, the standard specification of a copper-nickel tube can either be rectangular, round, oval, or square.
When should you Choose Copper Coil Heat Exchanger?
You need to consider using copper coil heat exchanger when:
- There is a need for high thermal conductivity. Copper allows for faster heat conduction.
- There is a need for a corrosion-resistant material. This is because copper does not easily corrode, which can affect the quality of your heat exchanger.
- Has a high-stress resistance. This allows for usage in heavy applications without causing damage to your heat exchanger.
- The ease of fabrication allows for cutting and modifying into various shapes. This means you can alter the design of your heat exchanger to fit your specifications.
What is the Thermal Conductivity of Copper?
Copper has a heat transfer coefficient of is 385.0 W/m K
How do you Bend Copper Nickel Heat Exchanger Tubes?
A tube pilot is a necessary tool when bedding a copper-nickel heat exchanger tube though the tube sheets and plates.
It features an aluminum grooved nose and replaceable nylon brush.
The tube pilot has shoulders on which the copper-nickel tube rests on during the installation process.
This minimizes the belling of the copper-nickel tube end and also reduces the “fin lock” effect on these tubes.
The overall diameter of your copper-nickel heat exchanger tube should correspond to that of your tube pilot.
When bedding, you have to start from the bottom of your exchanger towards the top.
The reason for this is for the bottom tube to offer support to give you a pattern for bedding at the next level.
When installing copper-nickel heat exchanger tubes on a shell and tube heat exchanger, the starting point is from the middle-lower row going upwards.
When you finish, you get to the next row and work again upwards until you finish every row on the heat exchanger.
By doing this, you can easily remove the tube pilot in case of dislodging within it.
