Description

technical field [0001] The invention relates to a forced air-cooled laser cooling system, which belongs to the technical field of laser generators. Background technique [0002] A laser is a device capable of emitting laser light. It is the core equipment for military and high-precision processing, and it is also one of the weapons and equipment that countries focus on developing. A laser is mainly composed of a pump source, a laser medium and a resonant cavity. Among them, the effective heat dissipation of the pump source is an important guarantee for the safe and stable operation of the laser. The current main cooling methods for lasers are as follows: [0003] 1. Forced air cooling is the most widely used heat dissipation method at present. Aluminum or copper heat sinks are usually used to increase the convection area, and then fans are used for forced convection air cooling to achieve the effect of heat dissipation. The design of the heat sink and the cooperation of t...

Problems solved by technology

[0006] 1. With the increase in the power of electronic equipment, single-phase flow circulation cooling is gradually difficult to meet the thermal management requirements under high heat flux density conditions

[0007] 2. The existing equipment adopts the method of immersion phase change cooling for the part with the largest heat generation of the laser, but the direct immersion cooling of this scheme cannot actually achieve a high heat transfer coefficient, and when the laser is working, its instantaneous power is too high, and If the heat is too large, film boiling may occur at this time, and the thermal conductivity and heat transfer coefficient will be seriously reduced
