Description

Technical Field

[0001] The utility model relates to a laser water cooling system, in particular to a semiconductor laser with a water cooling channel and a modular water cooling system. Background Art

[0002] The laser water cooling system mainly cools the laser by fixing it on a water cooling plate and using a water chiller and a water pump for cooling circulation. However, this traditional design has the following several significant problems:

[0003] Since the traditional laser water cooling system needs to be installed on a large water cooling plate and requires a water cooling compressor, the overall volume and weight are relatively large, which makes the system inconvenient for installation and transportation and limits its application scenarios.

[0004] Since the system mainly relies on the compressor for cooling, its functional structure is complex. Once the system fails, it often requires disassembly, installation, and repair of the entire system, increasing the maintenance difficulty and cost.

[0005] The heat dissipation of the traditional system depends on the overall design of the water cooling plate and the cooling circulation. The heat dissipation efficiency is limited by the physical properties of the water cooling plate and the design of the cooling circulation, and it is difficult to meet the requirements of efficient heat dissipation.
