The present invention adopts the production method of boiling and exhaust explained hereafter heat pipe type full-glass vacuum pipe and the difference of existing production method to be mainly following 4 aspects:
1, in the method for boiling and exhaust explained hereafter heat pipe type full-glass vacuum pipe provided by the invention, the processing of described glass inner tube is independently to finish, and after check, has only qualified glass inner tube just to enter next process.And be when finishing the inner and outer pipes welding of glass-vacuum tube in the prior art, pipe end welding condenser pipe is made heat pipe.Whether qualified the key technical indexes is: the sealing of glass inner tube and the amount of interior intraductal working medium and weigh all-glass vacuum tube, so prior art is had relatively high expectations to production equipment, production has high input, and production method provided by the present invention does not have extra high requirement to the working medium filling apparatus, so investment in production equipment is low, reduced production cost indirectly.
2, the present invention and the existing core that goes up the difference of product method are that exhaust process is to adopt boiling and exhaust technology, are about to working medium and are heated to boiling, and the working medium vaporized gas can be discharged the on-condensible gas that evaporates in the gas in the glass tube and the working medium.After the glass inner tube sealing-in, the steam of coagulable working medium is condensed into liquid state again, makes glass inner tube have higher vacuum.
3, in the production method that the present invention adopts, temperature is higher than the serviceability temperature of glass heat pipe during owing to vacuum exhaust, does not go wrong in process of production, and this product does not just have glass tube explosion problem when using.Improved reliability and the security of product when hot operation greatly.
4, evaporator section, the condensation segment of the interior pipe of the all-glass vacuum tube produced of method of the present invention are one, thereby have avoided weld inwall out-of-flatness in the two-part structure and influence the problem that working medium refluxes.
In addition, the production method that the present invention adopts is applicable to mobile automatic production line, also is applicable to fixedly exhaust station equipment.Every all-glass vacuum tube vacuumizing and exhausting approximately needs 10min in the existing production technology, and every all-glass vacuum tube boiling and exhaust only needs about 1min in the production method of the present invention, and its production efficiency is higher than existing production method far away.
In sum, reliability and the security of the all-glass vacuum tube that the method for boiling and exhaust explained hereafter heat pipe type full-glass vacuum pipe provided by the present invention is produced are good, have improved product quality; Simultaneously, also reduce production cost, improved production efficiency.
