Laser device in which a laser oscillation part, an air cooling machine and a dehumidifier are cooled by general cooling water

摘要

The laser apparatus includes a laser oscillation part including a water cooled plate, an air cooling machine including a radiator, a dehumidifier including a water cooled plate, and a cooling water feeding device including a cooling water pipe through which a cooling water is fed. The air cooling machine and the dehumidifier are arranged in a housing. The cooling water pipe is branched so that the water-cooled plate in the laser oscillation part, the radiator and the water-cooled plate in the dehumidifier are connected in parallel. The cooling water supply device supplies a general cooling water of the same temperature to the water-cooled plate in the laser oscillation section, the radiator and the water-cooled plate in the dehumidifier.
