热交换器包含散热器、空冷器、中冷器、油冷器、冷凝器等，当热交换器芯子由于氧化、腐蚀、机械损伤等原因造成破裂渗漏及其他缺陷后，在对热交换效果无较大影响的前提下，作为应急处理措施，可进行堵塞处理。一般认为：堵塞后无法疏通及因破损而施行堵塞处理的芯子不大于总数? Heat exchangers include radiators, air coolers, intercoolers, oil coolers, condensers and the like. When the heat exchanger core cracks, leaks and other defects due to oxidation, corrosion, mechanical damage and the like, Under the premise of no significant effect on the results, as a contingency measure, can be blocked. Is generally believed that: after the blockage can not clear and due to damage and blockage of the implementation of the core is not greater than the total number?
