挑战
全球高性能塑料供应商帝斯曼工程塑料在 LED 照明应用领域面临挑战。这些应用中使用的散热器主要由铝制成,负责将 LED 产生的热量散发到环境中。然而,尽管铝是一种良好的导热体,但也存在一些局限性,例如与加工压铸件相关的成本较高、设计自由度有限、可回收性问题和重量。帝斯曼试图为散热器提供基于塑料的解决方案来克服这些问题。为了找到由聚合物材料制成的散热器的最佳设计并预测其热性能,帝斯曼需要对自然对流和辐射冷却(LED 散热器向环境散热的机制)进行建模。我们面临的挑战是找到一种能够准确模拟这些过程并提供可靠结果的工具。

解决方案
DSM 在其开发流程中实施了 Altair Engineering 的产品 AcuSolve。 AcuSolve 是一款基于通用计算流体动力学 (CFD) 的软件,能够对各种热和流动问题进行建模。 DSM 使用 AcuSolve 模拟自然对流和辐射冷却。为了评估聚合物散热器的冷却能力,AcuSolve 与其他有价值的 CAE 工具一起使用。 AcuSolve 能够对自然对流的热损失进行建模,同时考虑到由于散热器表面附近的空气密度差异而导致的散热器周围气流的热损失。它还解释了由于边界层效应而导致的气流停滞,特别是当散热器设计的翅片间间距太小时时。此外,AcuSolve 能够使用 hemicube 算法对辐射热损失进行建模,同时考虑散热器不同部分的视角因素。这可以优化散热器设计,最大限度地提高环境中的辐射热损失。

Boiler Control System for Plastic Manufacturing Applications
Factory automation applications must be equipped to handle and monitor the myriads of information from attached devices. For plastic manufacturing applications, the boiler control system plays a critical role by gathering and regulating information to ensure production is accurate and smooth. In this particular case, the customer combines eight subsystems that include power meters, water meters, alarm output, displays, and I/O status to be controlled by several intelligent controllers with Modbus RTU interface. The Modbus TCP protocol is used for this application due to the distance. System Requirements: • Modbus serial to Modbus TCP translation • Multiple slaves/masters support • Automatic Modbus TCP response time detection

Ascend Performance Materials Case Study
Ascend operations must access multiple software systems to manage day-to-day operations in an effective and secure manner. These systems generate large sets of data which contain critical information pertaining to management systems, planning and cost information in business systems and energy consumption. As a result, Ascend management was challenged with creating relevant reports reflecting performance measures in overall context of their operational process. The company’s previous process entailed collecting and analyzing data manually which was not effective, since the information collected was generated after the fact, and was too complex for collaborative use across the organization.
