Nowadays, UVLED products are in the bud of the market. For people, it is more familiar with cold light sources. In fact, "cold light source" equipment is the same as general mechanical equipment, which is a great demand for heat dissipation of the body, especially Power chip for LED devices.

People who are most impressed with the demand for heat dissipation are not laptops. For notebooks, it is very important to formulate a reasonable heat dissipation layout based on the location of the heat source. Similarly, the heat dissipation of UVLED devices is extremely important for UVLED chips. and on the status of markets, UVLED lamp beads photoelectric conversion efficiency have yet to upgrade, UVLED lamp beads only about 20% of the electrical energy into light energy, other electricity are off as heat, causing the body temperature is too high influences. On this basis, the UVLED power supply is also a large heat dissipation, and its conversion efficiency becomes even more important!

The conversion rate of the power supply = output power / input power * 100% , the design and manufacturing process of the UVLED power supply is very high, the power conversion efficiency is high, the relative heat is lower, and the stability of the whole machine is also stronger. The conversion rate of high-end UVLED power products on the market is generally around 90% , but the conversion efficiency is not fixed. The conversion efficiency is the lowest at no load and full load, and the heat is also the largest. An excellent power supply, the operating temperature is generally not higher than 50 degrees, for example, the power core technology power supply is tested at 50 ° working temperature .

At present, the common cooling methods of UVLED equipment are self-cooling, water cooling and air cooling. The higher the power output of the equipment, the more heat is generated. Therefore, in pursuit of high power, the requirements of UVLED equipment and UVLED power supply for heat control. The higher.

When UVLED equipment enters the door of the era of high power, its requirements for heat dissipation technology are gradually increasing. Low-power equipment is generally air-cooled or self-cooling, but high-power equipment must use water-cooled means to cool down.
