Abstract

Further development in cutting-edge technologies becomes increasingly reliant upon the ability for massive heat removal. Boiling heat transfer offers the cooling capacity required by such emerging technologies. However, phase-change cooling schemes based on boiling heat transfer typically have two important limitations. First, high uncertainty in predicting the so-called ldquocritical heat fluxrdquo (CHF) that determines the maximum heat-removal capacity. Second, the inability to actively respond to fluctuating cooling demands due to the passive working principle. The present study seek to contribute to the advancement of phase-change cooling schemes by model-based development of control strategies that safely facilitate efficient boiling heat transfer close to CHF under dynamic operating conditions. These control strategies can be developed by means of a compact 3D model that describes the system-level dynamics of pool-boiling processes entirely in terms of the heat distribution within the heat-generating device. The compact 3D model and how to utilise it for the development of control strategies are the topics of this paper.

控制池沸腾:高性能冷却方案的一种方式?
尖端技术的进一步发展越来越依赖于大量散热的能力。沸腾传热提供了这种新兴技术所需的冷却能力。然而,基于沸腾传热的相变冷却方案通常有两个重要的局限性。首先,在预测所谓的临界热通量(CHF)时存在很大的不确定性,而CHF决定了最大的排热能力。其次,由于被动工作原理,无法主动响应波动的冷却需求。本研究旨在通过基于模型的控制策略的开发来促进相变冷却方案的发展,从而在动态操作条件下安全促进接近CHF的高效沸腾传热。这些控制策略可以通过一个紧凑的3D模型来开发,该模型完全根据产热装置内的热量分布来描述池沸腾过程的系统级动力学。本文的主题是紧凑的三维模型以及如何利用它来开发控制策略。
