Description

Technical Field

[0001] This utility model relates to the field of laser applications, and in particular to a surface-heated laser with an air-cooled structure. Background Technology

[0002] Industrial heating lasers, with their advantages of high precision, high efficiency, controllable energy, automation compatibility, environmental friendliness, energy saving, and non-contact characteristics, are widely used in fields requiring non-contact, precision heating, such as surface treatment and precision annealing of semiconductor wafers.

[0003] During operation, the surface-heated laser module generates a large amount of heat. Therefore, a heat dissipation module is installed at the bottom of the surface-heated laser. This module uses a fan for cooling. The fan rotates to cool the heat sink. The heat sink is relatively large, and the metal material in the center is thick, which can lead to inadequate heat dissipation and insufficient protection for the surface-heated laser module.

[0024] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, such as... Figures 1 to 5The device includes an outer frame 1, a base plate 2 mounted at the bottom of the outer frame 1, a laser module 5 mounted at the top of the base plate 2, a heat sink 3 mounted at the bottom of the base plate 2, a fan 4 mounted at the bottom of the heat sink 3, ventilation holes at the bottom of the heat sink 3, a spiral channel 7 on the inner side of the heat sink 3, and two rows of heat dissipation holes 6. The spiral channel 7 on the inner side of the heat sink 3 guides the air flow, allowing the air to move outward along the circumference. The two rows of heat dissipation holes 6 allow the internal air to be discharged, carrying away heat, thereby better protecting the laser module 5 and effectively improving the service life of the laser module 5.

[0025] The substrate 2 is a copper-based circuit board, which is used to fix the laser module 5.

[0026] The outer frame 1 has through holes on its outer side for hot air to escape, thus protecting the laser module and extending its service life.

[0027] Multiple heat sinks 8 are provided on the outside of the heat sink 3. The heat sinks 8 can increase the contact area with the air to accelerate heat dissipation.

[0028] The fan 4 includes a mounting bracket 41. A motor 43 is mounted on the inner side of the mounting bracket 41 via a bracket 42. The motor 43 rotates to rotate the fan blades 44, thereby achieving air circulation.

[0029] The mounting bracket 41 has mounting holes 45 at its four corners. The mounting holes 45 are used for bolts to pass through, so that the fan 4 can be fixed to the lower part of the heat sink 3.

[0030] The implementation principle of a surface-heated laser with a wind-cooled structure in this application embodiment is as follows: When the surface-heated laser with a wind-cooled structure is in use, the heat generated is conducted to the heat sink 3. The motor 43 rotates, the fan blades 44 rotate, and the external air flows in from the ventilation hole at the bottom of the heat sink 3. It flows inside the heat sink 3 and is guided by the spiral channel 7 to be discharged from the heat dissipation hole 6, thus taking away the heat inside the heat sink 3 and protecting the laser module 2.

[0031] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
