环境实验室冷却塔选型及使用注意事项

Selection and Appliance Considerations of Cooling Tower in Environmental Laboratory

环境实验室配备电动振动台、倾斜摇摆台、温湿度箱等军民用检测设备,多数设备需要冷却。风冷方案适用于小型检测设备,水冷方案适用于中大型检测设备。闭式冷却塔具有价格适中、冷却效果好、使用寿命长、易维护等特点,成为水冷方案的首选。分析了冷却塔选型需考虑的因素及使用注意事项,给出了冷却塔流量、换热面积等核心参数的计算方法,以及管路布置、流量不足或分布不均、压力不足、密封失效、防腐防冻等问题的解决方案。

The environmental laboratory is equipped with military and civil testing equipment such as electric vibration table,inclined swing table,temperature and humidity chamber,most of which need to be cooled.The air cooling scheme is suitable for small-scale testing equipment,and the water cooling scheme is suitable for medium and large-scale testing equipment.The closed cooling tower has the characteristics of moderate price,good cooling effect,long service life,easy maintenance and so on,becoming the first choice of water-cooling scheme.The selection and appliance considerations of cooling tower are analyzed.The calculation method of the core parameters such as the flow and heat exchange area of the cooling tower is given,as well as the solutions to the problems such as pipeline layout,insufficient or uneven distribution of flow,insufficient pressure,sealing failure,anti-corrosion and anti freezing.
