Zorlanmış taşınım ile yüksek parlak LED ekran sisteminin termal yönetimi ve analitik ve sayısal yaklaşımlarla soğutma performansı optimizasyonu

Thermal management of display devices is crucial for the long-term performance and life of the products. In line with customer demands, multipurpose display devices designed for operating in various environments must comply with high expectations of brightness. However, high brightness requirements mean considerable power consumption, leading to significant heat dissipation within the device. Analytical and numerical approaches are commonly used to optimize cooling performance by tailoring cooling system designs. The heat generation and dissipation inside the display systems could be modeled by using several numerical tools (e.g. ANSYS Icepak). The main objective of this research is to develop and optimize a cooling system that maintains the temperatures of critical components within safe operational limits, thereby keeping the overall reliability and efficiency of the display system. To achieve this, the study investigates various cooling methodologies while focusing on the combination of conduction and forced convection mechanisms to achieve the desired thermal management. Key findings show that a tailored cooling system, designed with a combination of conduction and forced convection, can significantly improve thermal management. The study proposes a design methodology that minimizes the number of components in the cooling system while allowing high cooling performance under harsh operating conditions. Comparison of analytical and numerical results and prototype testing validate the feasibility of the proposed cooling solutions. In summary, our study contributes valuable insights into the thermal management of high-bright LED displays. It offers practical solutions for indoor and semi-outdoor display applications. Future work will focus on further refining the cooling design and exploring advanced materials and technologies to enhance thermal performance.
