The cooling method of laser marking machine

  Laser marking machine uses laser beams to permanently label the surface of various substances. The role of marking is to expose deep substances through the evaporation of surface substances, thereby engraving exquisite patterns, trademarks, and text. Laser label machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, and fiber laser marking machines. The YAG laser marking machine is mainly used for some more detailed and more accurate occasions. It is used in electronic components, integrated circuits (ICs), electrical appliances, mobile phone communications, hardware products, tool accessories, precision instruments, glasses clocks, jewelry, car accessories, plastic buttons, building materials, PVC pipes.

  The cooling solutions of the laser marking machine are liquid cooling and air cooling, the option of thermal solution mainly depends on the power of the laser equipment itself. The working principle of liquid cooling and air cooling is the same, and both play a cooling role to ensure the normal work of laser marking machines. For example, the power of semiconductor laser marking machine is relatively large, generally we will design a liquid cooling heat sink, which has excellent thermal performance, and the disadvantage of liquid cooling is that the volume is quite large. Air cooling is generally suitable for small power CO2 marking machines, fiber laser marking machines, UV laser marking machines, etc. The air cooling heat sink has much smaller volume, and design a heat pipe heat sink or vapor chamber heat sink also has great thermal performance.
