80年代，大连内燃机车研究所首先将汽车水箱的管带式散热器技术推广应用于国产内燃机车销散热器上，研究开发成功6P管带式散热器，并装于东风4C型机车上。由于管带式散热器具有独特的优越性，因此已被路内、外生产厂家看好，迄今，已纷纷开发出4P、6P、7P（双流道）管带式散热器系列产品。然而，由于6P管带式散热器自身结构所致，使其刚性差，并导致泄漏这一惯性质量问题发生，对此应引起足够重视。本文针对6P管带式散热器刚性差问题，提出了提高其刚性的具体建议。
In the 1980s, Dalian Diesel Locomotive Research Institute firstly promoted the application of the tube-and-tube radiator technology of the automobile water tank to the domestically produced diesel locomotive radiator, and successfully developed the 6P tube-and-tube radiator and installed it on the Dongfeng 4C locomotive. Due to the unique superiority of the tube-and-tube radiator, it has been favored by the inside and outside manufacturers. Up to now, the 4P, 6P and 7P (double channel) tube and tube radiator products have been developed. However, due to the structure of the 6P tube-type heat sink itself, resulting in poor rigidity and lead to leakage of inertia quality problems, which should be given sufficient attention. In this paper, aiming at the rigid difference of 6P tube-and-tube radiators, some specific suggestions to improve its rigidity are put forward.
