Compact type dry ice air cooling laser heat dissipation system and method

Abstract

The invention discloses a compact type dry ice air cooling laser heat dissipation system and method. A scheme adopted in the invention employs dry ice to cool forced convection air for heat dissipation, and employs the cooled forced convection air to carry out heat exchange on a laser heat sink. Compared with an existing scheme, the scheme of the invention has the advantages that the space structure of the laser heat dissipation system is optimized, the phase change cold storage mode is large in cold storage capacity, cold can be rapidly released, and the problem that the air cooling heat dissipation capacity is limited can be solved.

Description

technical field [0001] The invention relates to laser technology, in particular to the heat dissipation technology of the laser. Background technique [0002] During the working process of the laser, the gain medium absorbs the energy of the pump beam and tends to generate heat. A large amount of heat will lead to uneven energy distribution inside the crystal, thereby affecting the output performance of the laser. The higher the input power of the laser, the more obvious the thermal effect. However, with the continuous development of laser advanced manufacturing technology, high input power is a major trend in today's development. Therefore, efficient thermal management technology is an important support to promote the continuous development of lasers. [0003] At present, the laser heat dissipation system mainly includes two types of methods: water cooling and air cooling. [0004] The water cooling method mainly uses a water cooler to cool the water, and sends it to the...

AI Technical Summary

Problems solved by technology

[0007] 1. Most of the existing air-cooled structures directly use fans and other devices to perform forced convection heat exchange on the laser heat sink. The heat dissipation effect is not good, the heat dissipation capacity is limited, and the use of high-power lasers is limited.

[0008] 2. Existing high-power lasers use water-cooled heat dissipation systems, but water-cooled heat dissipation systems suitable for high-power lasers are often bulky and complex systems

[0009] 3. The existing heat dissipation structure is generally designed according to the peak heat dissipation when the laser is running. When the laser is not running at high power, energy will be wasted

[0010] 4. Simply relying on air-cooled heat dissipation makes huge noise, which brings unnecessary troubles to users
