In the selection method of the laser chiller, the water flow and head of the chiller will directly affect the stable operation of the laser chiller in the future.

1) The flow rate of the chiller water pump is too small:

The direct effect of too small flow rate of the water pump is that the heat cannot be quickly taken out from the cooled equipment, causing the temperature of the cooled equipment to rise. And because the cooling water flow rate is not fast enough, the temperature difference between the inlet and outlet becomes larger, so the surface temperature difference of the temperature-controlled equipment is relatively large.

2) The chiller water pump flow rate is too large:

The large flow rate of the water pump makes the cooling effect of the chiller good and the cooling capacity large, which can meet the cooling requirements. However, an excessively large cooling water circulation pump will inevitably increase the equipment cost of the industrial chiller, and the operating cost such as electricity will also increase. The high cooling water flow and pressure will also increase the resistance of the water flow pipe, which will cause unnecessary energy consumption, reduce the service life of the cooling water circulating pump, and may cause many other failure
