Abstract

The invention relates to a built-in circulating passive cooling module and method for an air-cooled small-power solid laser of an all-in-one machine. The module comprises a module seat, the top of the module seat is provided with a cooling bottom plate for installing the laser, and the cooling bottom plate is internally provided with an S-shaped water channel. A water pump communicated with the hot water outlet of the S-shaped water channel and a water cooling disc communicated with the water pump are arranged in the module base, the outlet of the water cooling disc is communicated with the cold water inlet of the S-shaped water channel, an air outlet is formed in the side wall of one side of the module seat, and a water cooling disc fan set is arranged at the position, close to the air outlet, in the module seat. The water cooling disc is arranged between a water cooling disc fan group and the air outlet, and a power supply interface for controlling the water cooling disc fan group to work is arranged on the module seat. Large-air-volume fans and the water cooling disc are utilized, and the built-in circulating water device is additionally arranged, so that the cooling bottom plate provided with the laser can effectively and uniformly dissipate heat, and the low-power solid laser arranged on the cooling bottom plate can reach a dynamic stable state.

Description

technical field

[0001] The invention belongs to the technical field of laser beam processing, such as welding, cutting and drilling, and is particularly a compact passive cooling module suitable for an integrated machine of low-power air-cooled solid-state lasers. Background technique

[0002] The cooling methods of laser crystals in all-solid-state lasers can be roughly divided into three methods: "liquid cooling, semiconductor cooling, and air-cooling conduction heat dissipation".

[0003] Among them, liquid cooling can achieve a better cooling effect by controlling the temperature and flow of the liquid. It uses constant temperature water as the cooling method and requires a separate laser water cooler to provide cooling; the added laser water cooler has no advantages in terms of cost. It will not be able to meet the requirements in an environment with high humidity requirements.

[0004] Semiconductor (TEC) cooling needs to add heat sink fan cooling on the basis of semi...
