摘要/Abstract

摘要：

为了研究翅片数量、倾斜角度及相变材料对带有纵向翅片的电源散热器传热性能的影响，在恒定热负荷为16 W的条件对含相变材料和不含相变材料两类工况下的5种不同结构散热器进行了实验研究。通过搭建的由实验段、直流电源、数据采集设备等组成的实验系统开展实验，分析了翅片数量(1～5片)、散热器倾角(0°～90°)和相变材料(正二十烷)对散热器传热性能的具体影响，并通过含相变材料散热器的温升变化特征以及相变传热特征对散热器热性能进行了评估。结果表明，倾斜角度和翅片数对液相相变材料对流单元的形成以及传热和运行时间起着关键作用。对于0°倾角的含相变材料散热器，相比1个翅片，5个翅片达到最大允许温度所需的时间增加了80%，而当倾角增加到90°时翅片数的增加对时间的影响不显著。对于所有的倾斜角度，各个测点的相变材料(PCM)温度值都随着翅片数的增加而减小。当倾角增加时，由于浮力诱导流的增强促使对流液相相变区域变大；在单翅片工况下，60°倾角相比0°倾角状态下的工作时间延长78.6%。

Abstract:

In order to study the effects of fin number, inclination angle and phase change material on the heat transfer performance of power radiator with longitudinal fins, five different structure radiators with and without phase change material were experimentally studied under the condition of constant heat load of 16 W. The experiment is carried out through the experimental system composed of experimental section, DC power supply and data acquisition equipment. The specific effects of the number of fins (1～5), the inclination angle of the radiator (0°～90°) and the phase change material (n-eicosane) on the heat transfer performance of the radiator are analyzed experimentally. The thermal performance of the radiator is evaluated by the temperature rise characteristics and phase change heat transfer characteristics of the radiator containing phase change materials. The results show that the tilt angle and the number of fins play a key role in the formation, heat transfer and operation time of liquid phase change material convection unit. For the radiator with phase change material with an inclination of 0°, compared with one fin, the time required for five fins to reach the maximum allowable temperature increases by 80%, while when the inclination increases to 90°, the increase of the number of fins has no significant effect on the time. For all tilt angles, the PCM temperature at each measuring point decreases with the increase of the number of fins. When the dip angle increases, the phase transition region becomes larger due to the enhancement of buoyancy induced flow; Under the condition of single fin, the working time at 60° inclination angle is 78.6% longer than that at 0° inclination angle.

Key words: heat transfer characteristic, PCM material, fin structure, inclination of radiators
