1results about How to "Improve water cooling effect" patented technology

This invention belongs to the field of laser cladding and laser additive manufacturing, specifically relating to a synchronous water-cooled laser cladding head and method based on co-channel photon and powder. The head includes a cladding head body, on which a laser head interface, a photon channel structure, a metal powder channel, and a cooling water channel structure are disposed. The laser head interface and the photon channel structure are vertically connected, and the metal powder channel is connected to the photon channel. The cooling water channel structure comprises an inlet channel, an annular cooling cavity, and an outlet channel arranged sequentially from top to bottom. The annular cooling cavity surrounds the photon channel structure, and the outlet channel sprays cooling water onto the substrate to cool it. This invention uses an externally placed water-cooling channel to form an annular water curtain, effectively reducing the adverse effects of heat accumulation during the cladding process.
