Description

Laser installation seat with cooling system

Technical Field

The utility model relates to a laser instrument technical field specifically is a laser instrument mount pad with cooling system.

Background

With the development and progress of science and technology in recent years, the research and development and application range of lasers are rapidly expanded, and the lasers are widely applied to various industries, such as precision machining, medical operations, petrochemical industry, environmental detection, scientific research experiments and the like of semiconductors, flat panel displays, solar energy, microelectronics and other industries.

The laser can generate a large amount of heat during working, if the heat is not dissipated timely, the working efficiency of the laser light source and related working components can be affected, and even the laser light source and the components can be burnt possibly. With the continuous increase of laser power and the increasing miniaturization of device size, the thermal effect generated when the laser works has become a serious obstacle to further increase of output power, and effective cooling and strict temperature control measures must be adopted.

The laser device is required to be stably installed in a frame body which can dissipate heat and control temperature, and the frame body with the function can stably work for a long time, and is called a laser device installation seat (Housing), which is called a laser seat for short. The laser seat is the basis of the laser, and the laser head, the laser processing mechanism and the like are installed and fixed in the laser seat.

At present, the most widely used laser cooling method is to install a set of cooling water circulation system in the laser seat, the circulated cooling water pipe is coiled and fixed in the laser seat, and the cooling water usually reaches the flow of several liters to several tens liters per second to ensure the enough high heat dissipation coefficient. To achieve such high flow rates, the cooling system requires the use of large water pumps, large heat exchangers, large diameter piping, and large volumes of cooling water, which add to the bulk and weight of the laser system.

Use H type aluminum alloy laser seat, the size is 150 × 350 × 650mm as the example, purchase a monoblock aluminum alloy raw and other materials, thickness is about 150mm, hollowing out the material into the H type through machining's mode, see figure 1, adopt the copper pipe as cooling water circulation circuit, bend the copper pipe into required water route shape, install directly over the laser seat, fix in the semicircular groove with the screw, connect remaining cooling device, in order to realize that the cooling water circulates in the water pipe and flows, thereby take away the used heat that the laser instrument produced.

This cooling system, the installation of copper pipe is loaded down with trivial details, needs dozens of or even hundreds of screws to fix. If the radian and the flatness of the bent copper pipe are slightly out of tolerance or the design is slightly defective, the copper pipe cannot be installed in the groove or interferes with the laser module and the component. In addition, the more complicated the circulating flow channel is, the more the required length and bending times of the copper pipe are, and the larger the internal space of the laser seat is occupied. After the laser works for a long time, the copper pipe is easy to deform, and the sealing ring is aged, so that fatal influence can be brought to the laser.

In addition, a cooling method is adopted, a water channel loop is directly dug at the bottom of the laser seat without using a copper pipe, and then the laser seat is sealed by a cover plate and a sealing ring. Because the water course area is great, the apron if sealed improper, perhaps the sealing washer is ageing, can lead to the cooling water seepage, damages laser components and parts.
