Liquid cooling of LED car headlamps using polymeric hollow fibers
Original language description
Thermal management of high-power Light Emitting Diodes (LED) car headlamp is important because high temperatures decrease life span of LEDs significantly. Polymeric hollow fibers of a small diameter (approx. 1 mm) were used to create a compact liquid cooling systems of LED car headlights. The cooling performance of liquid cooling system installed on the headlight Printed Circuit Board (PCB) of Skoda Octavia and Skoda Enyaq was tested. Results of the testing show that the proposed plastic radiators ensure efficient and uniform cooling of the PCBs and keep the LEDs operation temperature much below the recommended 110°C. As the heat generation is relatively small for liquid cooling (tens of watts), there is only 3-10 l/hour flow rate of coolant needed, allowing to operate the plastic radiator with low velocity and pressure drops (below 1kPa).
