电气设备的功耗逐年增加，因此电力电子设备的热管理变得越来越重要。本文综述了自20世纪70年代末压电扇发明以来，在压电扇优化方面所取得的进展。能源消耗是高度相关的，也是贯穿始终的基本主题。重点放在为许多不同的应用优化设计所采用的方法上，并包括对这些过程的关键分析。对不同研究数据的比较突出了压电扇设计的既定规则，更重要的是，为了未来的发展，还确定了设计中尚未完全理解的方面。自2010年以来，数值建模已成为压电风扇设计优化的重要工具，此后的绝大多数出版物都在某种程度上包含了计算方法。对于热点冷却应用的单个压电风扇的优化是众所周知的，虽然一直是研究领域的基础，但在实际应用中并不构成最大的发展潜力，因为单个压电风扇不能取代任何大尺寸的冷却系统。相反，应该在未来几年大力考虑开发多风扇阵列，最终取代替代电力电子热管理系统。
Power consumption from electrical devices increases year upon year, and as a result thermal management of power electronics is becoming ever more relevant. This review summarises the advancements made in the piezoelectric fan optimisation since their invention in the late 1970s. Energy consumption is highly relevant, and is an underlying theme throughout. Emphasis is placed on the methods undertaken to optimise designs for many different applications, and critical analysis of these processes is included. Comparison of data taken from different studies highlights the well-established rules of piezoelectric fan design and, more importantly for future advancements, also identifies the aspects of design which are not fully understood. Numerical modelling has become an essential tool for piezoelectric fan design optimisation since 2010, and the large majority of publications since have included computational methods to some degree. The optimisation of a single piezoelectric fan for a hot spot cooling application is well understood and, whilst always fundamental to the research field, does not pose the greatest potential for development in real life applications, as a single piezoelectric fan cannot replace a cooling system of any great size. Rather, the development of multiple fan arrays, which could ultimately replace alternative power electronic thermal management systems, should be strongly considered in the coming years.
