Abstract

Laser-driven white lighting consists of blue laser diode (LD) and yellow phosphor, and it is attracting attention as a future lighting technology due to its advantages such as high luminous intensity, efficacy and the possibility of miniaturization. The optical efficiency of LD is highly affected by the temperature, cooling system is critical for many practical applications such as automotive headlamp. This study presents a single phase liquid cooling system which was selected for both higher cooling performance and lower consumption power. Also, a thermal dynamic model was proposed for predicting the LD temperature with experiment to validate the model. The system consists of an LD, heat spreader, heat sink and liquid pump. A heat spreader was designed with liquid cooling channels based on the model in consideration of both the thermal resistance and pressure drop. Also, the effect of surrounding ambient conditions was analyzed for considering real vehicle situation.

考虑周围环境条件的激光二极管冷却系统热动力学建模

激光驱动的白光照明由蓝色激光二极管(LD)和黄色荧光粉组成，由于其发光强度高、效率高、小型化可能性大等优点，作为一种未来的照明技术备受关注。温度对发光二极管的光学效率影响很大，冷却系统在汽车前照灯等许多实际应用中至关重要。本研究提出了一种具有较高冷却性能和较低功耗的单相液冷系统。提出了一种热动力学模型，并通过实验对模型进行了验证。该系统由LD、散热器、散热器和液泵组成。在此基础上，考虑热阻和压降，设计了带液冷通道的散热器。同时，考虑到车辆的实际情况，分析了周围环境条件的影响。
