内燃机车散热器单节由集水箱、扁铜水管及散热铜片等部分组成。工作时 ,热水从铜管中流过 ,风从水管间和散热铜片间吹过 ,从而带走水的热量 ,实现对热水进行冷却的目的。散热器在使用中 ,铜管常因出现裂纹而漏泄。由于铜管和散热铜片布置较密 ,从外部不容易查出漏泄的铜管 ,也 Diesel radiator single section from the water tank, flat copper pipes and cooling copper and other components. During work, the hot water flows through the copper pipe, and the wind blows between the pipe and the cooling copper to remove the heat of the water and achieve the purpose of cooling the hot water. Radiator in use, brass often due to cracks and leakage. Due to the dense arrangement of copper tubes and radiating copper sheets, it is not easy to detect the leaked copper tube from the outside, too
