多孔噴嘴-
Of the currently available coolers for electronic products with a high heat flux, micro - jets impingement cooling heat sinks are able to provide the best heat transfer performance : lowering the maxmal temperature and the temperature difference. the heat transfer for multiple jets impingement has been studied firstly for summarizing a few rules. and then a copper micro - jets impingement cooling heat sink consisting of five copper sheets is designed in this paper and the jet diameter is 0. 15mm
本文首先對陣列射流沖擊進行了實驗研究，總結了陣列射流沖擊的一些規律和特性，在此基礎上，根據數值模擬優化結果設計和製作了微射流陣列冷卻熱沉（射流孔直徑d = 0 . 15mm ） ，並採用去離子水和氮氣作為工質，對熱沉內流體壓降和傳熱特性進行了研究。 -
Within the core of a jet streak, flow speed may reach 200 to 300 km per hour with possibility of multiple maxima
急流中心風速有時可達每小時200至300公里，而且可以有一個或多個風速極大中心，具有強大的水平切變和垂直切變。
