Describe the heat dissipation problem and heat dissipation method of UVLED curing machineClick [211] Publish Time:2022-05-19

The heat dissipation problem of UVLED curing machine has always been an important problem in the development of UVLED curing machine. During the working process of UVLED curing machine, only about 20%-30% of the energy is converted into light energy, and about 70%-80% of the energy will be converted for heat energy. If the heat cannot be dissipated in time and effectively, it will have a great impact on the life and radiation intensity of UVLED lamp beads. As a UVLED curing machine manufacturer, Height-LED has been exploring and accumulating in the field of UVLED heat dissipation, and is committed to designing a better UVLED heat dissipation method, so that the UVLED curing machine can play its role better.


Before understanding the heat dissipation method of the UVLED curing machine, we first need to understand how much temperature affects the UVLED lamp beads. For example, at a temperature of 25 °C, the relative optical power of UVLED can reach 100%, while at 100 °C, it drops by at least 20%, and short-wave UVLED even drops by 60%. It can be seen that the temperature has a great influence, and the increase in temperature will greatly shorten the service life of the UVLED.

There are currently two types of UVLED curing machines: air cooling and water cooling. Air cooling reduces the temperature of the substrate by means of a radiator and a fan. The water cooling method is to take away the temperature on the lamp bead substrate by means of thermal convection and circulating cooling water, so as to achieve the cooling effect.


These two heat dissipation methods are also the mainstream heat dissipation methods in the industry. Height-LED strives for better heat dissipation by using high-quality fans, water coolers, and scientific and precise calculations on heat dissipation modules. At present, Height-LED high-intensity UVLED curing machine, equipped with a water-cooled box, can perform irradiation curing work at high intensity for a long time, which can basically meet the heat dissipation requirements of the equipment.


As a manufacturer of UVLED curing equipment, Shenzhen Height-LED is committed to providing customers with a complete set of curing solutions. The products have standard products and can also customize products according to customer needs. If you have UVLED curing requirements, you can contact online customer service, or call for consultation and exchange.
