Embodiment 1

[0062] Embodiments of the present disclosure provide an apparatus for air-cooling an optical fiber laser, the fiber laser in order to efficiently air-cooled.

[0063] In the prior art fiber laser typically water-cooled, water-cooled machine typically includes an external water cooler and built two programs.

[0064] If using an external cooling loop water-cooling machine, you need to buy water-cooled machine, leading to increased procurement costs, and in the time, power consumption is relatively large, resulting in increased cost, in addition to large area, resulting in movement of transport is very inconvenient.

[0065] If the machine with built-in water-cooled cooling cycle, power consumption is larger, it would still result in an increase in the volume of the fiber laser weight gain, not easy to move and transport.

[0066] And whether it is built using an external water cooler or water cooler circulates cooling water leakage accident occurs readily, and damage the electrical...

Embodiment 2

[0111] Embodiment 2 provides a housing comprising an air-cooling heat-cooling device of an optical fiber laser in Example No. 1, wherein the technical characteristics of the air-cooling heat-cooling device of the disclosed fiber laser are also suitable for this embodiment. The technical features of the disclosed air-cooling heat dissipation device are no longer repeated.

[0112] Combine Figure 1 to 8 as well as Figure 10 to 12 And see Figure 9 As shown, the housing 2 provided in this embodiment includes a housing 20 and a ventilation device 1.

[0113] Among them, the outer casing 20 is commonly known as the chassis, and the role of protecting the components mounted inside it. In order to facilitate observation of the inside of the outer casing 20, the view can be provided on the side of the outer casing 20.

[0114] In order to facilitate movement of the fiber laser 3 machine, improve the portability, the casing 31 can be provided at the bottom of the outer casing 20 to facilita...

Abstract

The invention relates to the technical field of lasers, in particular to an air cooling heat dissipation device of an optical fiber laser and the optical fiber laser. The air cooling heat dissipation device comprises a draught fan, a first radiator and a first heat dissipation body. An air inlet space, an air outlet space and a first air cooling space are formed in the first heat dissipation body; the fan is arranged at the air outlet end and sucks cold air towards the air outlet space; one end of the air inlet space is communicated with the air inlet end, and the other end of the air inlet space is blocked from the air outlet end; one end of the air outlet space is blocked from the air inlet end, and the other end of the air outlet space is communicated with the air outlet end; the first radiator is arranged in the first air cooling space, the first radiator is used for installing a pumping source of the fiber laser, and a plurality of first air cooling channels communicating the air inlet space and the air outlet space are formed in the first radiator. The optical fiber laser comprises the air cooling heat dissipation device. The air-cooling heat dissipation device and the optical fiber laser are large in cold air flow and high in heat dissipation efficiency, and can meet the air-cooling heat dissipation requirement of the high-power optical fiber laser.

Description

Technical field [0001] The present application relates to the field of laser technology, particularly relates to an optical fiber laser and fiber laser air cooling means. Background technique [0002] It refers to a rare earth doped fiber laser glass fiber as the laser gain medium. Fiber laser is widely used, including laser fiber-optic communications, laser distance space communications, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing roll, military and national defense security, medical equipment, large-scale infrastructure construction, other lasers as the pump source or the like. [0003] Fiber lasers working time will generate a lot of heat, to the laser requires constant cooling to maintain continuous operation, otherwise it will damage the laser. [0004] At present, water-cooled multi-fiber laser to the laser cooling to maintain normal operation. Although the water-cooled heat quickly, but there are still many pro...
