空气冷却器是利用空气冷却热流体的换热器。管内的热流体通过管壁和翅片与管外空气进行换热，所用的空气通常由通风机供给。今天我们来说一下如何清洗空气冷却器？
冷却水大多数含有钙、镁离子和酸式碳酸盐。当冷却水流经金属表面时，有碳酸盐的生成。另外，溶解在冷却水中的氧还会造成金属腐蚀，形成铁锈。由于锈垢的产生，冷却器冷却效果下降。严重时不得不在壳体外喷淋冷却水，结垢严重时会堵塞管子，使换热效果失去作用。研究的数据显示水垢沉积物对热传输的损失影响巨大，随着沉积物的增加会造成能源费用的加大。即使很薄的一层水垢就要增加设备中结垢部分40%以上的运行费用。保持冷却通道中不含矿物沉积物可以很好的提高功效、节约能源、延长设备的使用寿命，同时节约生产时间和费用。
长期以来传统的清洗方式如机械方法（刮、刷）、高压水、化学清洗(酸洗)等在对设备清洗时出现很多问题：不能彻底清除水垢等沉积物，酸液对设备造成腐蚀形成漏洞，残留的酸对材质产生二次腐蚀或垢下腐蚀，终导致更换设备，此外，清洗废液有毒，需要大量资金进行废水处理。
An air cooler is a heat exchanger that uses air to cool a hot fluid. The heat pipe in the tube is heated by the air outside the pipe wall and fins, and the air is usually supplied by the fan. Today, let's talk about how to clean the air cooler
Most of the cooling water contains calcium, magnesium and acid carbonates. When the cooling water passes through the metal surface, there is the formation of carbonates. In addition, oxygen dissolved in cooling water also causes metal corrosion and rust formation. As a result of fouling, the cooling effect of the cooler decreased. In severe cases, the cooling water must be sprayed outside the shell, and the fouling will clog the pipe when it is serious, and the heat exchange effect will be lost. Data from the study show that scale deposits affect the loss of heat transport greatly and increase energy costs as sediment increases. Even a very thin layer of scale, it is necessary to increase equipment in the fouling parts, more than 40% of the operating costs. Keeping the mineral deposits in the cooling channel can improve the efficiency, save energy and prolong the service life of the equipment. Meanwhile, the production time and cost are saved.
For a long time the traditional way of cleaning method (such as mechanical scraping and brushing), chemical cleaning, high pressure water (pickling) in the cleaning equipment has a lot of problems: can not completely remove scale deposits, acid corrosion caused by the formation of vulnerability on equipment, the residual acid of the material have two times of corrosion or corrosion under the scale, the end led to the replacement of equipment, in addition, the washing wastewater is poisonous, needs a lot of money for wastewater treatment.
