2. What is Secondary Degassing Machine

Secondary degassing machines further remove air and gases from heat pipes/vapor chambers before sealing.

Components first sit in a vacuum chamber before pumps evacuate leftover gas molecules.

Finally, targeted heating allows for the last traces of gas to fully evacuate from the chamber.

A tiny amount of gas can degrade thermal conductivity so secondary degassing machines ensure there are no leaks.

ASHRAE is a good resource to learn about thermal standards.

3.Value of Secondary Degassing for Heat Pipe Production

Helps produce higher quality product.

When primary degassing takes place, there are still likely gases left inside the wick and micro-channel system. These gases, if not removed, will prevent the flow of vapor during operation.

This causes an increase in thermal resistance which causes a reduction in overall performance. Secondary degassing machines ensure this does not happen.

Secondary degassing machines also allow uniform production of massive production quantities. This is why heat pipe producers can guarantee stable thermal components.

4.Principle

Secondary degassing machines operate using vacuum and heat.

Components are placed into the degassing chamber. The mass is slightly heated allowing gas to escape.

Vacuum pumps remove leftover air/volatile gases from the chamber. Sensors will detect pressure and temperature changes.

Once a stable vacuum has been held for the proper amount of time, components can move onto filling and sealing

As this process is highly repeatable, secondary degassing is automated for mass production consistency.

5. Parts of the Machine

Secondary degassing machine mainly comprises:

• Vacuum tank

Container that stores heat pipe/vapor chamber parts for degassing.

• Degassing heater

Allows outgassing of residual gases adsorbed on metal surfaces and inside wicks.

• Efficient Vacuum Pump

Pulls out the remaining air and volatile substances quickly to provide deep vacuum.

• PLC controls

Automatically controls temperature, pressure, and time.

• Vacuum and Temperature Sensors

Monitors temperature and pressure precisely.

Since precise control allows more reliable thermal components,

Individual components also need precision control.

6. Characteristics

Ideal secondary degassing machine will have these features:

• Capable of deep vacuum for degassing as many gases out of the system as possible
• Ability to automatically control temperature as well as process timing
• High volume capacity for production needs
• Design that can be integrated
• Has sensors and data logging to verify parts quality

Bangwin Machine engineers degassing machines that can operate stably for long periods of time.

7. Applications in Thermal Production

Secondary degassing machines are commonly used in these production lines:

• Heat pipe production line
• Vapor chamber production line
• High-performance electronic cooling module production
• LED & GPU thermal solution production

Take data center heat pipes as an example: low residual gas inside cooling components is vital for thermal performance. Secondary degassing provides users the ability to reach max thermal transfer.

Electric vehicle power modules are another example which benefit from secondary degassing. Only by optimizing the vacuum level inside heat pipes can we achieve stable performance.
