Abstract

The embodiment of the invention provides a two-phase immersed heat dissipation device for a fiber laser, and the device comprises a sealing box which is provided with a cavity for accommodating a phase-change working medium and the fiber laser, the phase-change working medium being an insulating working medium with a gas-liquid two-phase phase change characteristic, and the fiber laser being immersed in the liquid phase-change working medium in the sealing box; a cooling mechanism, arranged in the sealing box and used for being arranged on the upper side of the liquid phase change working medium in the sealing box. According to the invention, efficient heat dissipation of the fiber laser can be realized, and the surface temperature of the fiber laser can be controlled to be maintained within a preset range while the heat dissipation uniformity of each region on the surface of the fiber laser is ensured, so that a relatively good heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of fiber lasers, in particular to a two-phase immersion heat dissipation device for fiber lasers. Background technique [0002] Fiber laser refers to a laser that uses rare earth-doped glass fiber as the gain medium. Fiber laser can be developed on the basis of fiber amplifier. Under the action of pump light, it is easy to form high power density in the fiber, resulting in laser working substance The laser energy level "particle number inversion", when properly added to the positive feedback loop, can form the laser oscillation output. Fiber lasers are used in a wide range of applications, including: laser optical fiber communication, laser space long-distance communication, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing rolls, drilling / drilling of metal or non-metal Cutting / welding, military and national defense security, medical equipment, large-...
