2. Principle of Primary Degassing Machine 

Primary degassing machines evacuate air/gases from internal heat pipe parts before they are sealed. It degasses the necessary tubes/chambers prior to filling them with vacuum.

The machine will first preheat the chamber or pipe slightly then pump out any existing gases. Following evacuation, the machine will normalize internal pressure.

Gas molecules inside of heat pipes/sheets cause inferior heat conduction. Therefore, a proper degassing procedure is critical.

3. Importance of Degassing

Removing excess gas improves thermal performance. This is why production lines need to degas before sealing the heat pipe.

Gas serves as thermal insulation within the pipe. This means there is less effective vapor movement.

Gas also impacts internal pressure which can cause device malfunction if not regulated.

Thanks to the primary degassing machine, heat pipes can function properly every time.

4. Primary Degassing Machine Working Principle

The primary degassing machine works by applying vacuum.

Operators place the heat pipe parts into the chamber initially.

Then, heating elements slightly increase the part temperature.

Simultaneously, vacuum pumps turn on because heat induces degassing of retained gases. The pumps suck out air and volatile matter next.

Lastly, the pumps sustain the process at a steady pressure for a predetermined period. They prepare the parts for forwarding to secondary processing afterward.

IEEE papers are one of the sources where you can learn about thermal system research.

5. Primary Degassing Machine Parts

There are many important systems that a modern primary degassing machine is composed of.

• Vacuum Chamber

Operators place heat pipe parts that require degassing into this chamber specifically. It stores the parts at a controlled pressure.

• Heating System

Heating elements assist in releasing absorbed gases from the metal and wick.

• Vacuum Pump

These powerful pumps suck out the remaining air and volatile gas in the chamber.

• Control System

A PLC controller controls the time, pressure, and temperature of the process.

• Monitoring Devices

Vacuum and Temperature sensors are used to monitor the changes during processing.

Since proper process control determines the quality of end products, all parts must be calibrated well.

6. Technical Specifications

The main technical advantages of purchasing a good primary degassing machine are as follows.

The machine is equipped with automatic control. This allows it to have stable degassing conditions.

Parameters can be set according to different sizes of the finished product.

It is equipped with high-performance vacuum pumps to improve degassing speed.

Due to the short degassing time, the production line can produce more heat pipes.

The equipment is simple in structure and can be quickly integrated into the existing heat pipe production line.
