某型散热器泄漏问题分析及改进

Analysis and Improvement of the Leakage Problem of a Certain Type of Radiator

某型产品在严寒地区开展适应性试验,其配套的散热器散热管根部出现开裂,导致散热器出现泄漏现象,严重影响产品的使用。文章通过对散热器设计结构、材质、防冻液加注过程及断口进行分析验证,确认因防冻液加注方法存在缺陷,导致散热器内部空气未排除干净,在低温下散热器左右区域热不平衡,散热管发生疲劳开裂。因此,采取了完善散热器防冻液加注方法、明确加注量的整改措施对问题进行整改,进而对整改后的车辆进行试验验证,解决了散热器泄漏问题,提高了产品的可靠性,对类似产品的设计与生产具有借鉴意义。

During the adaptability test of a certain type of product in the severe cold area,the root of the radiator heat pipe cracked,which led to the leakage of the radiator and seriously affected the use of the product.In this paper,through the analysis and verification of the design structure,material,antifreeze filling process and fracture of the radiator,it is confirmed that due to the defects in the antifreeze filling method,the internal air of the radiator is not removed clean and the heat is out of balance in the left and right area of the radiator at low temperature,fatigue cracking occurs in the heat pipe.The rectifying measures of perfecting the filling method of radiator antifreeze and defining the filling amount are adopted to rectify the problem,and the test verification of the rectified vehicle is carried out,which solves the problem of radiator leakage and improves the reliability of the product.It can be used as a reference for the design and production of similar products.
