Application Solution of ELAPLUS Thermal Conductive Material in Data Centers

2025-02-20

The data center is crowded with intensive servers running resource intensive processes, facing significant challenges related to heat. Overheating can limit server performance to prevent hardware damage, resulting in efficiency losses, while prolonged overheating can accelerate wear and tear, increase hardware failures, and increase the risk of costly downtime. These issues highlight the urgent need for advanced thermal management solutions to ensure optimal performance, reliability, and sustainability of high-performance data centers. In this article, let’s learn how to transform thermal management using advanced data center TIM solutions. Traditional solutions such as phase change films will deteriorate after repeated insertion and removal, such as the solution required for pluggable optical modules (POM). This degradation not only reduces thermal performance, but may also introduce volatile compounds into the data center environment, thereby damaging sensitive electronic components.In addition, these traditional methods often cannot handle the increased power density of newer transceiver designs, and the power density of each module may exceed 20W or even 35W. Due to each line card having up to 32 modules, accumulating thermal load becomes a key challenge. These inefficiencies can lead to overheating, increased energy consumption, and increased cooling costs, ultimately affecting the performance and sustainability of data centers.Given these realities, a top switch manufacturer is seeking a new innovative thermal control solution to reduce the operating temperature of its 20W transceiver application.Why effective thermal conductive material (TIM) solutions are crucial for data centersTIM plays a crucial role in bridging the small air gap between heating components and cooling solutions such as radiators or heat diffusers. If there is no effective TIM, these air gaps will become thermal barriers, reducing heat transfer efficiency and leading to various problems. The TIM solution for data centers ensures the following advantages:Avoiding performance degradation: Overheating can cause the processor and other components…
