摘要

对轨道交通应用的多种不同结构的水冷散热器进行了试验研究，对比不同类型流道对散热器流阻和散热性能的影响，得出了目前轨道交通常用的典型流道的散热特性。研究结果表明，散热器可通过减少流道长度，合理设置间距和齿槽排列等方法有效减少流阻；柱型流道和焊接翅片型流道可有效增加扰流，显著提高散热效果；焊接翅片型流道热阻和流阻相对较小和成本低，在高热流密度散热时更具优势。

Abstract

A variety of different structures of water-cooled radiators used in rail transportation were tested and compared. The effects of different types of flow channels on the flow resistance and heat dissipation performance of radiators were compared, and the heat dissipation characteristics of typical flow channels commonly used in rail transportation were obtained. The research results showed that the flow resistance can be effectively reduced by reducing the length of the flow channel and the reasonable setting of the spacing and the arrangement of the grooves; the cylindrical flow channel and the welded fintype flow channel can effectively increase the turbulence and signi fi cantly improve the heat dissipation effect. The thermal resistance and flow resistance of the welded fin type flow channel are relatively small, and the cost is low, which is more advantageous when the heat dissipation requirement of high heat flux density is required.
