[UVLED Hot Conduction] Several Concepts of UVLED Hot Transfer Method

Designing a complete set of UVLED curing devices involves more and more complex knowledge, including electronics, software engineering, mechanical structure, optics, heat science, material science, etc. Several ways to pass. 1> Environmental air can usually take away the calories of UVLED through three channels, which are transmission, convection and radiation. In fact, air conduction has little effect on UVLED, because the air guidance rate of air is very small, 0.02W/m-K. , Basically, you can ignore its thermal conductivity. 2> The circulation often occurs in a fluid with a temperature difference, because the difference in temperature will cause different density between fluids. The convection is more complicated, which is related to the size and state of the objects in the air and the nature of the air. In particular, the location, size and shape of other objects around the object must be considered. 3> The temperature is higher than the absolute zero-degree object can generate heat radiation. The higher the temperature, the greater the total energy of radiation. The radiation follows the law of Stefan-Boltzmann. Radiation of the rate. The UVLED heat conduction method used in the industry mainly includes liquid cooling, cold, and self -cold. Which thermal conduction method is used to design and select according to different power density and process requirements.
