Core Viewpoint - The article emphasizes the critical role of thermal management in the performance and reliability of electronic devices, driven by increasing power density due to advancements in technologies like 5G, AI, and IoT. Effective heat dissipation solutions are essential to prevent device failures and ensure optimal operation [7][10][15]. Group 1: Thermal Density and Management - The rise in power density of electronic components necessitates advanced thermal management solutions, as temperature increases can significantly reduce system reliability [7][10]. - The failure rate of electronic components increases exponentially with temperature, with a 50% reduction in reliability for every 10°C increase [7][8]. - The thermal flow density has surged from under 10W/cm² to nearly 100W/cm², driven by both increased power and reduced chip sizes [11][15]. Group 2: Passive Cooling Solutions - Passive cooling methods, which do not use active components, include materials like metal heat sinks, graphite films, and heat pipes, relying on thermal interface materials (TIMs) to transfer heat away from components [23][26]. - Metal heat sinks are effective for low-power devices but face limitations in high-power applications due to their thermal transfer rates [28][31]. - Graphite films have been widely adopted in consumer electronics for their high thermal conductivity in the X-Y plane, although their Z-axis conductivity is limited [32][33]. Group 3: Active Cooling Solutions - Active cooling methods, such as forced air cooling and liquid cooling, are becoming necessary as device power levels increase beyond the capabilities of passive systems [68][69]. - Liquid cooling systems can achieve heat dissipation rates of 10-1000W/cm², significantly outperforming air cooling methods [73][74]. - Data centers are increasingly adopting liquid cooling solutions to manage the rising power density of servers, with some configurations exceeding 30kW per cabinet [80][81]. Group 4: Market Opportunities and Beneficiaries - Companies involved in the development of advanced thermal management solutions, such as VC (vapor chamber) technology and liquid cooling systems, are positioned to benefit from the growing demand for efficient heat dissipation in high-performance electronics [49][54]. - Key players in the market include companies like Feirongda, Suzhou Tianmai, and others that are innovating in thermal management technologies [5][6].
