The heat pipe is a device that effectively transfers heat through phase-change of the internal working fluid, and is a two-phase closed system. A general heat pipe is fabricated by maintaining a vacuum state on the inside and then injecting a working fluid that has undergone a degassing process. Such a degassing method has no problem in fabricating individual heat pipes but requires more time to manufacture heat pipe heat exchangers that require many heat pipes. Therefore, the present research proposed a method of manufacturing a heat pipe by using induction heating that can be heated to a degassing temperature in a short time and compared thermal performance with a heat pipe fabricated by the existing method. This study conducted numerical analysis and experiments using 5/8 in and 1 in diameter copper pipes. The error was found to be up to 7%; however, the trends between numerical analysis and experimental data were almost consistent. Based on the numerical analysis results, induction heating manufactured heat pipes under conditions of 90 V and 32 A. In addition, thermal resistance was measured, similar to the thermal resistance of heat pipe fabricated by the conventional degassing method. The manufacturing method by induction heating was validated by comparing thermal resistance with the existing method. It is expected that the manufacturing time of heat pipes can be meaningfully reduced and applied to the manufacture of heat pipes under various conditions using numerical analysis.
