    工业降温用到的【翅片管】是否越多越好

    翅片管主要的作用用来散热冷却的,但是不是冷却用的机器上翅片管的翅片越多越好呢?答案当然是否定的,要想问为什么,小编下面就给大家讲一讲原因。工业降温用到的【翅片管】是否越多越好
    The main function of finned tube is to heat and cool, but the more fins the finned tube has on the machine that is not used for cooling, the better? The answer is, of course, negative. If you want to ask why, Xiaobian will tell you why. The more finned tubes used for industrial cooling, the better.
    1、当翅片管翅片的传热面积增加一倍时,其换热系数并不能增加一倍,而是要打一个折扣,一般为(0.9-0.7)。这说明,翅片越多,翅片效率就越低,增加翅片的经济性就下降了。
    1. When the heat transfer area of finned tube and fin is doubled, the heat transfer coefficient can not be doubled, but should be discounted, generally (0.9-0.7). This shows that the more fin, the lower the efficiency of fin, and the economic increase of fin will be reduced.
    2、翅片太高太密,会增加工艺难度,提高加工成本。
    2, the fins are too high and too dense, which will increase the difficulty of the process and improve the processing cost.
    3、如果翅片太高太密,容易产生积灰问题,而且清灰困难。
    3, if the fins are too high and too dense, it is easy to cause ash accumulation and difficult to remove dust.

    The more finned tubes used for industrial cooling, the better.
    所以选用多少的翅片管是要靠计算翅化比来看的,也就是增加翅片以后的总传热面积除以未增加翅片是的总面积之比。而按照正常的规定,一般认为翅化比在5到10左右为最好,所以大家在选择翅片管时一定要合理选择选择,物极必反这个道理也是很有道理的。
    So how many finned tubes are selected depends on the finning ratio, that is, the ratio of the total heat transfer area after increasing fins divided by the total area without increasing fins. According to the normal regulations, the finning ratio is generally considered to be the best between 5 and 10. Therefore, when choosing the finned tube, we must make a reasonable choice. It is also reasonable that the extreme must be contrary to the extreme. 辛苦整理.转载请注明http://www.wxsxsjx.com
