ABSTRACT

A common heat exchange method used for most new designs is the use of heat sinks such as short pin fins. This experimental study investigated the static pressure characteristics developed in a short pin fin. Different fin array arrangements, fin longitudinal and transverse spacing ratios and individual slot heights in the fin were investigated. It was found that the row removed arrangement has superior flow efficiency, but to enhance heat transfer the staggered array is a better choice; the greater the fin spacing and slot height in each fin are, the less the pressure loss was experienced in the array.

开槽短针阵列静压特性的实验研究

摘要

用于大多数新设计的常见热交换方法是使用散热器，例如短针翅片。本实验研究调查了短针翅片中产生的静压特性。研究了不同的翅片阵列布置、翅片纵向和横向间距比以及翅片中的各个槽高度。结果发现，移排布置具有优越的流动效率，但为了增强传热，交错排列是更好的选择；每个翅片的翅片间距和槽高越大，阵列中的压力损失就越小。
