How to protect laser source in winter-Wilson

How to protect laser source in winter

In the cold winter, when the air temperature is lower than 0 °C, the

liquid water will condense to form a solid, and in the process of

solidification, the volume will become larger; this will "crack" the

pipelines and components in the water-cooled system ( The chilled water

system includes a chiller, a laser, and an output head). During the

installation and commissioning of your company, please pay attention to

the antifreeze before using it. After the commissioning is completed, the

QBH output cable and laser must be filled with antifreeze and stored or

sent to the customer to avoid loss caused by freezing damage during

storage and transportation.

How to avoid laser antifreeze on the client is a key issue in winter laser

maintenance. We will inform you about the use of laser antifreeze

protection measures and hazards in winter, and please remind your

customers again to avoid losses.

一. If there is no power outage in the local area, the water cooler will not

be turned off at night, and at the same time, energy saving, low

temperature and normal temperature water temperature will be

adjusted to 5 ~ 10 °C, to ensure that the coolant is in a circulating state

and the temperature is not lower than the freezing point.

二.Use antifreeze as coolant

Antifreeze must be used when the environment is often blacked out and济南新天科技有限公司

there are no conditions for daily coolant venting. The base liquid of

antifreeze is generally composed of alcohol and water. It requires high

boiling point and flash point, large specific heat and conductivity, low

viscosity at low temperature, not easy to foam, and does not corrode

metal parts and rubber hoses. When selecting or blending antifreeze, the

freezing point should be 5 °C lower than the lowest temperature in the


1.Antifreeze selection

Add professional brand antifreeze to the water cooler, such as Clariant's

AntifrogenN antifreeze, which is added in a ratio of 3:7 (3 for antifreeze,

7 for water), and can resist -20 ° C without freezing after adding

antifreeze. If the temperature is lower than this range, please consult the

water cooler supplier to confirm the proportion of antifreeze.

If the professional brand is not convenient to buy, you can purchase the

large-capacity car antifreeze shell OAT-45°C, which can be directly used

in the laser water cooling system. The dilution ratio can refer to the

following table. Please compare the actual temperature according to the

place of use, due to the use environment and water cooling machine.

The reason for the configuration, the actual use will affect the flow rate

and flow rate of the coolant, causing the water cooler flow alarm or the

laser heat dissipation problem. If the temperature is abnormal, please

contact our company after-sales personnel.济南新天科技有限公司

2. Antifreeze use precautions

Any antifreeze cannot completely replace deionized water and cannot be

used for a long time throughout the year. After the winter, the pipeline

must be cleaned with deionized water or purified water, and deionized

water or purified water should be used as a coolant.

At the same time, during the holidays such as the Spring Festival holiday

or during the long power outage, please drain the water in the pipeline

related to the laser and water cooler.

3. If is fine ,it is better for water chiller working continuously.

4. If your laser machine did not use for long time ,please drain the water

chiller,cutting head,and laser source out ,do not leave water inside
