摘　　要：微通道相变换热技术可较好地解决集成电路散热问题,近年来已成为传热学领域的研究热点之一。为满足国家“双碳”人才培养需求,增强本科生对新型换热技术的深入了解,研制一套微通道内相变流动可视化教学实验系统。实验系统由加热系统、可视化热沉室、测量系统以及相关管路和元器件组成,其中通道宽度为1 mm,既能形成微通道沸腾流动,又便于学生观察实验现象。实验时通过调节水流量和加热功率来控制沸腾程度,以呈现独立气泡、塞状流、弹状流、环状流等典型气泡特征及其转变过程,实验过程生动有趣、启发思考,可增强学生对基础知识的理解,提高创新能力。Micro-channel phase transition thermal technology can solve the heat dissipation problem of integrated circuits,and has become one of the hot topics in heat transfer field in recent years.In order to meet the needs of national"Carbon peaking and Carbon neutrality"talent training and enhance undergraduate students'in-depth understanding of the new heat transfer technology,a visualization teaching equipment of micro-channel phase change flow has been developed.The equipment consists of a heating system,a visual heat chamber,a measurement system,and associated piping and components.The width of fluid channel in heat chamber is 1mm,which can not only form micro-channel boiling flow,but also facilitate naked eye observation.The boiling degree is controlled by adjusting water flow and heating power to present typical bubble characteristics and transformation process such as independent bubble,plug flow,slug flow and annular flow.The experimental process is vivid and interesting,inspiring thinking,which can strengthen students'understanding of basic knowledge and improve their innovation ability.
