The invention discloses a method for coating an electric heat pipe with an electric thermal film. The method includes the following steps of: a, installation preparation: pushing a strut to allow the electric heat pipe to completely stretch into a spraying pipe; b, spraying the electric thermal film: pre-heating electric thermal film solution to 75-85 DEG C in advance, starting a motor to allow the electric heat pipe to rotate uniformly, then starting a centrifugal pump to pump the electric thermal film solution into a diversion pipe, atomizing the electric thermal film solution by an atomization pipe, closing the centrifugal pump after 8-10min, and pushing the strut to pull the electric heat pipe out of the spraying pipe; c, baking the electric thermal film: pre-heating a heating layer in a baking pipe to 300-400 DEG C, rotating a support plate to allow the head end of the electric heat pipe to face the inlet of the baking pipe, until a first stop dog abuts against a second stop dog, pushing the strut to allow the electric heat pipe to completely stretch into the baking pipe, pushing the strut to pull the electric heat pipe out of the baking pipe after 10-12min, separating the electric heat pipe from a fixing bracket by a special fixture and cooling naturally. The method can achieve better energy-saving and emission-reducing effect and lower cost.
