Abstract

The objective of this paper is to study the effect of multiple jet impingements on one another in a heat sink under adiabatic conditions. The jet impingement is a unique design which aimed to optimize the cooling performance of a concentrated photovoltaic cell. The paper is based on the design and fabrication of a new 9-celled test section. Initially, to set a baseline, individual cells in the 9-celled test section were tested alone in order to observe their flow regimes. These tests were completed by applying varying water cross flow rates to a set air-water mass flow rate exiting the jet impingement. Afterwards, two cells were tested in conjunction with one another under similar conditions. The location of the cells tested had been varied in order to observe how different cells interact with another. Plug flow and bubbly flow were consistently found through the various experiments. In general, it was noticed at higher crossflow rates the bubble sizes and quantity would decrease drastically.
光伏电池热管理用混合式散热器的研制
本文的目的是研究绝热条件下散热器中多个射流相互撞击的影响。射流冲击是一种独特的设计,旨在优化聚光光伏电池的冷却性能。本文是基于一种新型九室试验台的设计与制作。最初,为了设定一个基线,单独测试9个细胞测试区的单个细胞,以观察它们的流动状态。这些测试是通过将不同的水交叉流量应用于给定的空气-水质量流量来完成的。之后,两个细胞在相似的条件下相互结合进行测试。为了观察不同的细胞如何相互作用,测试细胞的位置被改变了。在各种实验中均发现了塞流和气泡流。一般来说,在较高的横流速率下,气泡的大小和数量会急剧减小。
