UV-LED Liquid Cold Plate

UV-LED Liquid Cold Plate

Uniform irradiation and brightness are required for UV-LED lighting.
We design a uniform cooling flow path exclusively for UV-LEDs. It evenly cools the LED device at once, and thus achieves uniform irradiation and brightness.

Want to know the reason why the brazed Liquid Cold Plates can:

  • Reduce more temperature
  • Achieve uniform cooling

Uniform cooling flow path design made uniform irradiation possible

  • Problem

    A general flow path generates temperature variation on the surface of a liquid cold plate.
    In other words, general liquid cold plates cause fluctuation in UV LED irradiation amount, and this would affect the product quality of the irradiated body.

  • Solution

    Uniform cooling of heat sink surface reduces fluctuations in the amount of UV irradiation and enables efficient irradiation of the irradiated object.
    We have much experience and skill in designing the best flow path to provide uniform cooling.
