摘　　要：基于浸没燃烧技术研究了热交换器的热传递过程,用热交换媒介来分析管道外部的水流速、平均对流传热系数及管长、风机功率消耗之间的内在关联。同时,结合分析结果对不同功率的加热装置进行测试、分析,通过数据拟合得到管道外部水槽的功率消耗和最大水浴流速之间的多项式,可为同一类型浸没形式的热交换机设计提供重要参考。Based on the immersion combustion technology,this paper studies the heat transfer process of the heat exchanger,and uses heat exchange medium to analyze the internal relations among the flow velocity,average convective heat transfer coefficient,pipe length and fan power consumption outside the pipe.At the same time,combined with the analysis results,the heating devices with different power are tested and analyzed,and the polynomials between the power consumption of the external water tank and the maximum water bath velocity are obtained by data fitting.The conclusions of the study can provide an important reference for the design of heat exchangers of the same type of immersion.
