  • Heat exchanger for friction stir welding apparatus and associated system and method
    Patent number: 12377490
    Abstract: A heat exchanger for a self-reacting friction stir welding apparatus includes a collar. The collar includes a collar flow inlet, a collar flow outlet, and an internal conduit fluidically coupling the collar flow inlet and the collar flow outlet. The heat exchanger also includes a rotary union having a first rotary-union flow outlet fluidically coupled with the collar flow inlet, a first rotary-union flow inlet fluidically coupled with the collar flow outlet, a second rotary-union flow inlet, and a second rotary-union flow outlet. The rotary union is co-rotatable with the collar. The heat exchanger further includes a manifold that has a first manifold flow outlet fluidically coupled with the second rotary-union flow inlet and a first manifold flow inlet fluidically coupled with the second rotary-union flow outlet. The rotary union is rotatable relative to the manifold.
