The chiller is a standard cooling equipment for laser cutting machines, laser welding machines, and laser cleaning machines. The core parameter of a chiller is the cooling capacity. Generally, when it is unclear how to select a chiller, high power is preferred. High power cooling capacity is sufficient to ensure the normal operation of the laser. The cooling capacity of the chiller will vary due to factors such as environmental temperature and humidity. So, what factors are related to the cooling capacity of the laser chiller?
The factors that affect the cooling capacity of the laser chiller mainly include the following aspects:
1. Under the same ambient temperature conditions. The higher the outlet temperature, the greater the cooling capacity. The lower the outlet temperature, the smaller the cooling capacity.
2.The magnitude of water flow directly affects the heat transfer rate. The larger the water flow rate, the greater the cooling capacity, while the smaller the water flow rate, the smaller the cooling capacity.
3.The voltage is unstable and the equipment cannot operate at full load. When the equipment reaches its rated power, the cooling effect is the best.
4.The diameter of the equipment condensation pipeline. The larger the condensing tube, the greater the cooling capacity, while the smaller the condensing tube, the smaller the cooling capacity.
5.The forms of evaporators are divided into water tank coil type, shell tube type, plate type evaporators, etc. The different form of evaporator and its coolant can also affect the overall cooling effect.
6.Compressor power. The higher the power, the greater the cooling capacity of the chiller. The lower the power, the smaller the cooling capacity of the chiller.
7.After the filter screen is blocked, the dust on the condenser will accumulate more and more, and over time, the cooling effect will become worse and worse. It is necessary to regularly replace and clean the filter screen to maintain good cooling effect.
In summary, many factors affect the cooling capacity of the chiller, and human intervention is required to ensure the optimal cooling effect. When selecting the chiller power, redundancy should be left to ensure that the laser can operate normally in some extreme situations. The cooling of the chiller should be an indispensable and important part of laser equipment, and everyone must be cautious when selecting the type.
