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.

The utility model belongs to the field of octagonal hatching box machines, and particularly relates to a ventilation structure of an octagonal hatching box machine, which comprises a case, an air inlet pipeline is fixedly arranged in the middle of the case, air outlets are arranged on two sides of the upper end of the case, a water cooler is fixedly arranged in the middle of the inner side of the case, and a ventilation fan is arranged on the water cooler. A mounting frame is fixedly mounted in the case, a bearing seat is fixedly mounted at the upper end of the mounting frame, and a bearing is fixedly mounted in the bearing seat. The two air inlet pipelines are arranged in the middle of the machine body for air inlet, the two sides of the machine body for air outlet, and the bottoms of the air inlet pipelines extend to the positions close to the centers of the fan blades, so that the negative pressure of the air inlet pipelines is greatly increased, the air speed in the air inlet pipelines is greatly increased, and the uniformity of airflow in the equipment is optimized; and through uniform distribution of the water cooler structure from top to bottom, the water cooling effect is greatly improved, and the concentration of carbon dioxide in the machine body can be reduced.

The application belongs to the field of hydraulic systems, and discloses a digital intelligent temperature control heat dissipation system, which comprises a heat dissipation device, a temperature control assembly, an oil inlet pipeline and an oil outlet pipeline, the heat dissipation device comprises a fan and a composite heat dissipation assembly arranged at the air outlet end of the fan, and the composite heat dissipation assembly is communicated with a hydraulic station through the oil inlet pipeline and the oil outlet pipeline. The effective combination of water cooling and air cooling can be realized through the composite heat dissipation assembly, the oil network pipe component can be pre-water-cooled through water cooling of the water cooling chamber, and further air cooling can be realized through the heat dissipation structure similar to the capillary pipeline under the action of air cooling, the cooling liquid after absorbing heat in the water cooling chamber can be air-cooled through the network air cooling part, so that the cooling liquid can be water-cooled for a longer time, and the network air cooling part and the pipe connection part of the air cooling area are staggered, so that air cooling and heat dissipation can be realized for both at the same time under the air cooling action of the fan.
