Below are simplified diagrams for two basic air-cooling configurations of Access Laser products. In both cases, air flow is directed toward the laser. Air cooling must be symmetrical distributed on both sides, otherwise the laser can develop thermal-mechanical distortion over long periods of time.
The heat sinks on the laser are designed so that standard 60 mm or 50 mm square fans can be mounted directly to the laser, as shown in the photo to below. With a L15 for example, you can choose six 30 CFM fans and mount three of them on each side symmetrically, using self-taping screws (#6-7/8” or equivalent).
