工業降溫用到的【翅片管】是否越多越好

翅片管主要的作用用來散熱冷卻的，但是不是冷卻用的機器上翅片管的翅片越多越好呢？答案當然是否定的，要想問為什麼，小編下面就給大傢講一講原因。工業降溫用到的【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、當翅片管翅片的傳熱面積增加一倍時，其換熱系數並不能增加一倍，而是要打一個折扣，一般為（0.9-0.7）。這說明，翅片越多，翅片效率就越低，增加翅片的經濟性就下降瞭。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，會增加工藝難度，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，容易產生積灰問題，而且清灰困難。3, if the fins are too high and too dense, it is easy to cause ash accumulation and difficult to remove dust.工業降溫用到的【翅片管】是否越多越好The more finned tubes used for industrial cooling, the better.所以選用多少的翅片管是要靠計算翅化比來看的，也就是增加翅片以後的總傳熱面積除以未增加翅片是的總面積之比。而按照正常的規定，一般認為翅化比在5到10左右為最好，所以大傢在選擇透水地坪翅片管時一定要合理選擇選擇，物極必反這個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 rat印花地坪io 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.轉載請註明http://www.wxsxsjx.com
