Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide laser tubes, in particular to a carbon dioxide laser tube lens heat dissipation structure. Background Art

[0002] Carbon dioxide laser tubes, also known as glass-encapsulated CO2 lasers, are commonly referred to as laser tubes because of their glass tube-encapsulated structure. Laser tube specifications are primarily based on laser power. Laser tubes are typically used in laser engraving and cutting. High-power lasers generate significant heat, necessitating the development of heat dissipation structures for the laser tube lens to protect the laser tube. However, existing CO2 laser tube lens heat dissipation structures lack comprehensive heat dissipation, resulting in low efficiency and inability to adjust and secure the structure to suit different laser tube sizes.

[0003] There is currently a carbon dioxide laser tube lens heat dissipation structure with Chinese patent publication number CN211605640U. Through the arrangement of an equipment body, an adjusting bolt and a fixing block, when a user uses the carbon dioxide laser tube lens heat dissipation structure and needs to fix the laser tube inside the equipment body, the user can fix the laser tube by rotating the adjusting bolt so that it is fixed inside the equipment body. This solves the problem of not being able to fix it according to different laser tubes and also improves the professionalism of the work. In addition, through the arrangement of a graphene layer, a liquid cooling pipe and a ceiling fan, when a user uses the carbon dioxide laser tube lens heat dissipation structure, when the laser tube generates a large amount of heat due to operation, the graphene layer will transfer the heat to the outside. During this period, the liquid cooling pipe will water-cool the laser tube to assist in heat dissipation and improve the heat dissipation efficiency. When the temperature is still too high, the motor can be turned on to drive the ceiling fan to rotate. The high-speed rotating airflow will dissipate the maximum amount of heat from the laser tube, thus solving the problem of not being able to dissipate heat in all directions and improving work efficiency.

[0004] However, the device has a limited cooling angle, poor cooling performance, and poor practicality. Utility Model Content
