  • Method of manufacturing heat exchanger tube and heat exchanger
    Patent number: 7802716
    Abstract: The present invention provides a method of manufacturing a heat exchanger tube in which a tube for a heat exchanger formed by brazing is manufactured using a sheet material, wherein a filler metal melted during brazing can be prevented from entering an opening formed in an opposing portion or a parallel portion formed when bending a sheet material into a tube shape or an opening facing toward the outside of the tube. The opposing portion, the parallel portion, or the opening facing toward the outside of the tube is sealed. As the sealing means, friction welding is preferable.
