Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber cooling, in particular to an optical fiber cooling plate. Background Art

[0002] As the output power level of high-power fiber lasers continues to increase, the heat problem has become a restrictive factor that restricts the further increase of the output power of fiber lasers. How to efficiently, quickly and conveniently remove the waste heat from the optical fiber has become an important research topic in the field of fiber lasers.

[0003] Currently, the heat dissipation methods commonly used by high-power fiber lasers are metal heat conduction, heat dissipation colloid contact heat dissipation, air cooling and water cooling, among which water cooling generally has a better effect.

[0004] Water cooling generally includes direct and indirect cooling, which is determined by whether the water coolant directly contacts the optical fiber to be cooled. Direct cooling is significantly more effective than indirect cooling. Existing direct water cooling methods generally place the optical fiber to be cooled in a water cooling tank, and then directly introduce the water coolant into the tank. However, optical fibers have a length property. To ensure the effective length, the optical fiber to be cooled is generally placed in a coil in the water cooling tank. To ensure uniform heat dissipation, an involute groove is generally provided at the bottom of the water cooling tank. The optical fiber is then embedded in the groove and secured with a clip or lock to prevent the optical fiber from falling out of the groove.

[0005] The above-mentioned cooling device has the following problems: (1) In order to ensure that the optical fiber can be effectively fixed in the cable trough, the bottom surface of the optical fiber is in contact with the cable trough over a large area, and only the top surface is in contact with the water-cooling liquid and heat exchange occurs, resulting in uneven heat exchange; (2) The clip or lock shields and squeezes part of the top surface of the optical fiber, resulting in extremely poor heat dissipation effect in this part. Utility Model Content

The wire fixing plates 20 are arranged along the radial direction of the cooling groove 11. The top surface of the wire fixing plate 20 is vertically recessed with multiple wire embedding grooves 21. All the wire embedding grooves 21 are evenly spaced along the length direction of the wire fixing plate 20 and pass through the wire fixing plate 20 along the width direction. The side walls of the bottom of the wire embedding groove 21 are dug with wire clamping grooves 22 radially inward or outward along the cooling groove 11. The widths of the wire embedding grooves 21 and the wire clamping grooves 22 are slightly larger than the diameter of the optical fiber to be cooled.

[0033] The optical fiber cooling disk provided in this embodiment is provided with a base disk 10, and an annular cooling groove 11 is opened on the top surface thereof, a groove cover 12 is provided, and a water inlet pipe 13 and a water outlet pipe 14 are provided to form a direct contact water cooling foundation, and cooling water circulation is realized by providing a water cooler to ensure the water cooling effect; on this basis, a plurality of wire fixing plates 20 are provided in a ring shape, a plurality of wire embedding grooves 21 are vertically recessed on the top surface of each wire fixing plate 20, and a wire clamping groove 22 is radially dug at the bottom of the wire embedding groove 21, and the widths of the wire embedding grooves 21 and the wire clamping grooves 22 are limited to be slightly larger than the diameter of the optical fiber to be cooled. When in use, the optical fiber to be cooled is pressed into a wire embedding groove 21 (the outermost one) of a wire fixing plate 20, and then is pressed into the wire embedding grooves 21 of the adjacent wire fixing plate 20 in sequence, and this is carried out in sequence. After the outermost circle is embedded, it is embedded inward in sequence to make the optical fiber gradually open. The optical fiber is fixed in a linear manner, and the elasticity of the optical fiber itself will make the optical fiber further clamped from the wire embedding groove 21 into the wire clamping groove 22, thereby effectively preventing the optical fiber from falling out. The optical fiber can also be manually clamped into the wire clamping groove 22 when embedding. Through this arrangement, the optical fiber is suspended in the cooling groove 11 in an involute shape, and is fully and evenly in contact with the water-cooled liquid for heat exchange.

When the slot cover 12 is covered with the base plate 10, the fastening rings 121 are embedded in the corresponding front wire embedding groove 21.

[0038] In order to improve the water flow rate of the gap between the optical fiber and the wire clamping groove 22, the groove wall of the wire clamping groove 22 is a cylindrical surface, and the diameter of the wire clamping groove 22 is slightly larger than the diameter of the optical fiber to be cooled.

[0039] In order to further prevent the optical fiber from contacting the groove wall of the wire clamping groove 22 , a plurality of nozzles 221 are radially provided on the groove wall of the wire clamping groove 22 , and all the nozzles 221 are connected to an air pump 24 .

[0040] Through the above arrangement, the air pump 24 is used to supply air, so that the nozzle 221 sprays air radially inward, so that the optical fiber in the cable clamping groove 22 is separated from the groove wall of the cable clamping groove 22 under the action of the air flow, thereby effectively avoiding the contact between the optical fiber and the groove wall of the cable clamping groove 22, and further avoiding the problem of uneven heat exchange.
