[0002] A laser galvanometer consists of an XY optical scanning head, an electronic drive amplifier, and optical reflective lenses. Its operating principle is to direct the laser beam onto a scanning mirror, which is then controlled by a computer at its reflection angle. These two mirrors scan along the X and Y axes, respectively, thereby deflecting the laser beam and focusing the laser light at a specific power density onto the material. Because the precision and quality of the material are inextricably linked to the galvanometer, the stability of the galvanometer system determines the material's performance. Galvanometer systems are typically mounted above a workbench, and the workspace requires a certain temperature to ensure stable sintering of the material. Consequently, the base of the galvanometer system is also subject to high temperatures, affecting system stability.
[0003] Currently, most laser forming machine galvanometer systems do not have cooling devices. A small number of them have cooling structures, which are all integrated inside the laser galvanometer. This is not only expensive, but also has high maintenance costs once damaged.

There are multiple threaded holes, and the positions of the multiple threaded holes correspond to the positions of the bolt mounting holes of the laser galvanometer. The cooling fan is located below the mounting groove and connects the mounting groove with the bottom surface of the cooling base.
[0008] Furthermore, a plurality of evenly distributed support blocks are provided at the bottom of the mounting groove on the periphery of the cooling fan.
[0009] Furthermore, the liquid circulation cooling channel includes two water inlet channels and one water outlet channel, wherein one of the water inlet channels extends from the left side of the cooling seat body to the right side of the mounting portion, and the other water inlet channel extends from the left side of the cooling seat body to the left side of the mounting portion, and the water outlet channel extends from the left side of the cooling seat body to the right side of the mounting portion, and the ends of the two water inlet channels are connected to the water outlet channel through a common channel.
