UVLED curing equipment - why use water-cooled heat dissipation


In order to improve curing efficiency and shorten curing time, more and more manufacturers are preferentially choosing high-power UVLED curing machines. However, high-power UVLED curing machines require higher cooling conditions due to the large heat generated per unit and high heat dissipation requirements. So currently, water-cooled circulating heat dissipation is a relatively good solution.

So when using water-cooled UVLED curing lamps, we should pay attention to the following:

1. When using UVLED curing machines with chillers, attention should be paid to equipment information exchange. When the chiller malfunctions, it can notify the UVLED device to turn off the light source to avoid thermal damage to the UVLED device caused by cooling failure.

2. The chillers of water-cooled UVLED curing machines generally use water as the coolant, because water is the most easily obtainable and inexpensive, and water has good chemical stability, high specific heat, non toxicity, non combustion, non explosion, and less corrosion to metals than saltwater. However, when using tap water or purified water for a long time, scale will form on the radiator wall, which has a certain insulation effect and can affect heat conduction. Suggest using distilled water or water tank.

3. It is best to control the working temperature of the chiller below 30 degrees, as the chiller mainly operates as a compressor, cooling the hot water circulating out of the UVLED lamp head, and then sending the cold water into the UVLED lamp head. If the temperature is too high and the compressor cannot work effectively, then the cooling capacity will significantly decrease, which will not effectively reduce the temperature of the UVLED lamp head.

As we all know, the lifespan and effectiveness of any device are related to our daily usage habits and reasonable and appropriate maintenance, and water-cooled UVLED curing machines are no exception, which also require maintenance and upkeep
