Laser chiller

Laser chillers are often used to cool UV lasers, CO2 laser glass tubes, semiconductor lasers, CO2 RF tube lasers, and fiber lasers for cooling cutting machines, marking machines, engraving machines, and other equipment. The user can choose the applicable chiller according to the different power of the laser.

The laser chiller is an individual application of industrial refrigerators to the laser industry. The laser chiller mainly cools the laser generator of the laser equipment by water circulation, and controls the operating temperature of the laser generator, so that the laser generator can be maintained for a long time. normal work. During the long-term operation of the laser equipment, the laser generator will continuously generate high temperature, and if the temperature is too high, the normal operation of the laser generator will be affected, so a laser chiller is required for water circulation cooling and temperature control.

According to the type of laser generator and the classification method of chillers, laser chillers are divided into carbon dioxide glass laser tube laser chillers, carbon dioxide metal RF tube laser chillers, semiconductor side pump laser chillers, semiconductor end pump laser chillers, and YAG lasers. Chiller, fiber laser chiller, UV laser chiller.

Laser marking is the most popular industrial processing method that emerged in the late twentieth century. Domestic companies engaged in the research and development, production and processing of laser marking machines, laser engraving machines, laser welding machines, laser inkjet printers, laser cutting machines and other laser processing equipment continue to emerge. The quality of the cooling system is a key part of the entire laser marking operation.

1. What is a non-start-stop chiller and how to choose one?

The non-start-stop chiller actually controls the refrigerant flow in the chiller to control the temperature of the refrigeration circulating water. According to the manufacturing principle of the chiller, it is divided into two control methods. The refrigerant flow direction control method is adopted within 5 degrees, so that the chiller can accurately control the temperature at plus or minus 0.1 degrees, and the compressor start-stop method is used outside 5 degrees. Make the chiller work energy-saving without the need for intense cooling. Based on the working mode of the chiller, the cooling accuracy requirements of the chiller can basically be met (for those with high accuracy requirements, the control method of the refrigerant flow can be used).

The rest is the cooling power and the selection requirements of the water pump. As long as the specific calorific value is considered, you can choose a chiller with different cooling capacity, and then look at the head and flow requirements of the water pump, and choose a different water pump. This will allow you to find the right chiller.

2. The heat dissipation capacity of the chiller CW-3000AG is 50W/℃. How to understand this value and unit and what is the basic heat dissipation principle?

The heat dissipation is the parameter of power and temperature change obtained after balancing the temperature by exchanging the heat-generating components with the temperature higher than the normal temperature air with the normal temperature air. 50W/degree Celsius means that each degree higher than normal temperature can dissipate 50W of heat. The CW-3000 series exchanges heat between the heating components of the target object and the normal temperature air through its own water and heat exchanger, so as to achieve the purpose of heat dissipation. It is a compact device for economical cooling.

3. How to calculate the amount of cold water in the chiller, it is often seen that the model of the chiller is represented by "HP" (horse), but how many tons is the amount of cold water?

Can it be calculated?

The amount of cold water is generally expressed by RT, but there are three types of cold tons: American cold tons, Japanese cold tons and British cold tons. What we usually talk about and the most commonly used are American cold tons, which are expressed by US.RT, and US is the United States. The abbreviation is 1US.RT=3516.7W, and HP refers to the input power unit of the chiller compressor. Generally, a 1HP compressor can have a cooling capacity of 2500W. Of course, some chillers use a 1HP compressor, and the system may only There are 2300W, and 1HP of some chillers may be 2800W.
