Manufacturing process of suction core heat pipe

Manufacturing process of suction core heat pipe

As mentioned earlier, the three main components that make up a heat pipe are the shell, core, and working fluid. After making a reasonable selection of materials for the shell and core during the design process, production can begin. The manufacturing process of heat pipes usually includes the following process operations and is carried out according to certain procedures.

1. Mechanical processing -2. Cleaning -3. Core production -4. Cleaning -5. Welding -6. Leakage detection -7. Degassing -8. Leakage detection -9. Filling -10. Sealing -11. Baking -12. Inspection

In actual manufacturing, it can often reach 20 or even hundreds of processes. Here are just some of the simplest necessary processes.

Gravity heat pipe manufacturing process

At present, the commonly used heat pipes in the field of energy conservation (waste heat recovery) are gravity heat pipes. Gravity heat pipes are mainly composed of three parts: shell, end cover, and working fluid. The usual manufacturing process is as follows:

1. Mechanical processing (shell and end cap, or direct procurement) -2. Pre treatment (shell and end cap degreasing and rust removal) -3. Drying -4. End cap welding (argon arc welding, welding joint polishing) -5. Filling working fluid -6. Exhaust air (baking) -7. Head welding (argon arc welding) -8. Inspection

The key processes are: 6. Exhaust air, 7. Head welding

Spinning head is a commonly used form both domestically and internationally. Spinning head is formed by directly spinning on a spinning machine. This type of end cover has a beautiful appearance, good strength, and saves materials and labor, making it a good form of end cover.
