摘要/Abstract

摘要： 为研究海拔对车辆散热器翅片性能的影响，编写了基于Matlab 的管带式散热器计算程序，在验证仿真程序正确的基础上，分别计算不同热物理条件下百叶窗翅片、平直翅片、波纹翅片、锯齿翅片4 种常见翅片散热器在不同海拔地区的空气侧和水侧出口温度、空气侧压降、空气侧换热系数、散热量等参数; 分析了海拔变化对不同翅片散热器散热能力的影响，对比了不同翅片散热器在变海拔下的散热特性和风阻特性．由综合换热系数可知，百叶窗翅片的散热能力最强，锯齿形翅片的海拔适应性最好．

关键词: 散热器翅片, 海拔, 散热特性, 风阻特性

Abstract:

In order to reveal the effect of altitude on the performance of vehicle radiator fins,the simulation program for tubular radiator is developed in Matlab environment.After verifying the correctness of the simulation program,the air-side and water-side outlet temperatures,the air-side pressure drop,the air-side heat transfer coefficient and the heat dissipation of radiators with four common fins ( namely louver,straight,wavy and serrated fins) are calculated under different thermal physical conditions at different altitudes.Then,the cooling capacity of different radiator fins are analyzed under the influence of various altitudes,and the heat transfer performance as well as the wind resistance performance of different radiator fins at various altitudes are analyzed in a comparative way.It is found from the obtained comprehensive heat transfer coefficient that louver fin is of the strongest cooling capacity,while serrated fin is of the best adaptability to altitude.

Key words: radiator fin, altitude, heat transfer performance, wind resistance performance
