1. What is Heat Pipe Manufacturer?

Heat pipe manufacturer refers to the company that can design and make heat pipes, test and supply to customers.

Heat pipes are used to conduct heat from high temperature area to low temperature area.

By using the evaporation and condensation principles to conduct heat.

So heat pipes have an advantage to transfer heat in a more efficient way without any mechanical motion.

Professional heat pipe manufacturer can make various structure of heat pipes according to the requirement of the products.

Like straight heat pipes, curved heat pipes, flat heat pipes or some special heat pipes.

They can also make heat pipes for heatsink, laptop, server, GPU, industry electronic and auto electronic.

A full service heat pipe manufacturer can supply more than just heat pipes.

During the production line, we can also help you to prepare the material, cut the casing, clean, fill powder, sinter, vacuum, charge working fluid, seal, form and test.

If you want to know more about heat pipe production line you can check out our article Heat Pipe Production Line and Heat Pipe Assembly Equipment.

2. What is Heat Pipe?

Heat pipe is a kind of thermal conducting device that can transfer heat from one place to another.

There will be working fluid and wick structure inside the heat pipe.

Normally there are three main areas of a heat pipe.

• Evaporator
• Adiabatic
• Condenser

When heat pipe contact the heat source. The evaporator section will get heated.

Working fluid will absorb the heat and become vapor.

Then the vapor will move towards the condenser section which has a lower temperature.

The vapor will release the heat and turn back to liquid state.

The wick will help to send the liquid back to the evaporator.

The heat pipe will repeat the above process.

That is why heat pipes can transfer heat at a large rate with a small size.

Copper is the most widely used heat pipe material.

Because it has great heat conduction ability and can work with common working fluids.

You can learn more about heat pipes in our articles Heat Pipes and Heat Pipe Heat Sink.

3. How Does Heat Pipe Work?

Learn about the working principle of heat pipes will help you understand why we need to manufacture heat pipes professionally.

3.1 Evaporate

When the heat source heats up the evaporator.

The working fluid will absorb the heat.

And change to vapor state.

3.2 Vapor Movement

The vapor will move inside the heat pipe towards the condenser.

During this process the heat will be transferred from heat source.

3.3 Condense

When the vapor reach the condenser area.

It will release heat and turn back to liquid.

3.4 Liquid Return

The liquid will return back to evaporator through the wick.

So that the heat pipe can continue the cycle.

All these happen inside a closed loop system.

That is why vacuum and seal is very important during the heat pipe manufacturing process.

4. Why Need A Professional Heat Pipe Manufacturer?

To produce a heat pipe we need to control each process properly.

Any small problem during the manufacturing can lead to bad heat pipe performance.

So we need a professional production line with advanced equipment to produce heat pipes.

Product Quality

With professional production process we can make sure the heat pipe size, vacuum, wick structure and working fluid amount is qualified.

Custom Size

Every product need different size of heat pipes.

We can help you to customize the heat pipe:

• Size
• Thickness
• Curvature
• Structure
• Bending angle
• Wick
• Working fluid

Testing

Professional heat pipe manufacturer can provide testing service for your heat pipes.

Like leak test, vacuum test, size and heat transfer performance.

Mass Production

Professional heat pipe production line can help you to make sample and mass production.

5. Heat Pipe Types

Heat pipe manufacturer can make many different types of heat pipes.

5.1 Circular Heat Pipe

Circular heat pipe is the most common type of heat pipe.

It has a simple structure and can be applied in many products.

Heat pipe manufacturer can produce heat pipes in different diameter and length.

5.2 Flat Heat Pipe

Flat heat pipe can reduce the thickness of the product.

So it can be used in slim electronic devices.

Like laptops, tablets, phones and other slim computers.

5.3 Curved Heat Pipe

We can bend heat pipes to fit different products.

It can be used to make some complex products.

So curved heat pipes are mostly used in heat sink.

5.4 Sinter Heat Pipe

By sintering copper powder we can create a wick structure inside the heat pipe.

The capillary force of sintered wick can push liquid faster.

So it is widely used in heat pipes.

5.5 Groove Heat Pipe

Use groove as the wick structure inside the heat pipe.

This can also help to send the liquid back to evaporator.

5.6 Mesh Wick Heat Pipe

Another type of wick is mesh.

We can use different type of mesh structure for heat pipes.

5.7 Heat Pipe Assembly

Heat pipe manufacturer can also make heat pipe assembly.

Which means we can install heat pipes onto the heat sink.

Check out our article Automated Heat Pipe Assembly Line Supplier to learn more.

6. Heat Pipe Material

Different material can bring different properties to heat pipes.

6.1 Copper

Copper is one of the most used material to make heat pipe.

It has high heat conduction value.

And can work with water as working fluid.

So copper heat pipes are used in many electronic devices.

6.2 Aluminum

Aluminum is lighter than copper.

So if your product need lighter weight you can use aluminum heat pipes.

But you need to choose the right material and working fluid combination.

6.3 Wick

There are many types of wick that can be used in heat pipes.

Such as:

• Sinter powder
• Mesh
• Groove
• Combine structure

Depending on the requirement we can choose the best wick for your heat pipes.

7. Heat Pipe Manufacturing Process

There are many steps to produce heat pipes.

And every step can affect the final result of the heat pipe.

Below is a general heat pipe manufacturing process.

Step 1 Prepare Material

Prepare the copper tube or other material that you want to use.

Make sure the size meet your requirement.

Step 2 Auto Cut Casing

Cut the tube to the length you need.

Using automatic casing cutter can help you cut the tube faster and with better accuracy.

You can check out our article Automatic Casing Cutter.

Step 3 Clean

Clean the casing before making the wick and filling powder.

Make sure no oil or dirt left on the casing.

Step 4 Fill Powder

Fill the copper powder into the heat pipe casing.

You need to control the amount and distribution of the powder.

You can use our automatic powder filling machine to help you.

Step 5 Sinter

Put the casing into the sintering oven.

After heating the copper powder will stick together and form the wick structure.

You can learn more in our article Vacuum Sintering Oven.

Step 6 Forming

We can form the heat pipe into different shapes.

Depending on your product requirement we can make different type of heat pipes.

Step 7 Vacuum

Remove the air inside the heat pipe.

To make sure the heat pipe has a good vacuum level.

This is a very important step before we charge the working fluid.

You can read more in our articles Vacuum Degassing Machine and Degassing Machine.

Step 8 Charge Working Fluid

Charge the working fluid into the heat pipe.

Water is the most commonly used working fluid.

Step 9 Seal

Seal the heat pipe after vacuum and charging the working fluid.

Step 10 Test

Test the heat pipe before shipping it out.

8. Heat Pipe QC and Testing

Testing is very important when you are making heat pipes.

Here are some ways we can test your heat pipes.

Size

We can measure the size of the heat pipe.

Including:

• Length
• Diameter
• Thickness
• Flat
• Bending angle
• Ending size

Wick

Make sure the wick structure is good inside the heat pipe.

We can control the powder filling and sintering process to get a good wick.

Vacuum

Measure the vacuum level of the heat pipe.

A bad vacuum level can affect the heat transfer performance.

Leak Test

Make sure the heat pipe is sealed properly and there is no leak.

Heat Transfer Performance

We can also test the heat transfer performance of the heat pipe.

Appearance

Make sure the heat pipe look good and no scratch or deformation.

9. Heat Pipe Application
