钢制板式散热器为啥会响？
在行业群也好，公司客户群也好，经常会碰到反映钢制板式散热器发出噪音的，虽然也简单的讲过一些，但没有系统的整理出来。
In the industry group or customer group, we often encounter the noise emitted from the steel plate radiator. Though it is also briefly mentioned, it has not been systematically sorted out.
今天老胡就稍微整理一下常见的几种钢制板式散热器噪音成因吧，看完了也许你会发现，很多噪音的形成，并不是散热器本身造成的。当然，具体的成因各种各样，不一而足，碰到这里没有描述的，就需要各位自己仔细观察分析了。
Today is Hu tidying up a bit of several common steel plate radiator noise causes it, watching perhaps you will find that the formation of a lot of noise, and not the radiator itself. Of course, there are a variety of specific causes, which are not described here. It is necessary for you to observe and analyze them carefully.
1、水流声
1. The sound of water flow
这种是比较常见的，也比较容易判断，一般都是散热器里面有空气没有排放干净。处理方法也比较简单，只要对系统进行排气补水的操作即可。
This is more common, and it is easier to judge. Generally, there is no clean air in the radiator. The processing method is also relatively simple, as long as the operation of the system is carried out.
2、快速而连续的震动声音
2. Fast and continuous vibrate sound
我们先来看一个视频
Let's look at a video first
这个声音并非散热器本身发出，而是由循环泵、阀门及管道组合产生。请检查阀门是否有堵，以及进回水管是否有接反。这种是比较少见的。
This sound is not emitted by the radiator itself, but is produced by a combination of circulating pumps, valves and pipes. Please check whether there is a plug in the valve, and whether there is a connection between the inlet and the back pipe. This is relatively rare.
3、金属碰击声
3, metal rattle
再来看下面一个视频。
Look at the following video.
相信有不少经销商或者终端用户有碰到这种情况，特别是对于长片（超过1.4m长的），用尽全身法术，还是无法消除。而有的同样的散热器安装在不同位置的，却又完全没有声音。然后就认定是钢制板式散热器本身有问题。
It is believed that many dealers or end users have encountered this situation, especially for long films (over 1.4m long), which can not be eliminated by exhaustion of whole body magic. And some of the same radiator is installed in different positions, but there is no sound at all. Then it is found that the steel plate radiator itself has a problem.
而这个声音出现的时间，如果仔细观察一下，会发现都发生在散热器热起来或者冷却下去的过程中。
And the time of the sound, if you look carefully, will find it happened during the heat or cooling of the radiator.
老胡可以肯定的说，这也不是散热器本身发出的声音！不信？你把散热器一头稍微从挂架上托起，你就会发现，这可恶的声音就消失了。
To be sure, this is not the voice of the radiator itself! Don't believe it? If you lift the radiator a little up from the hanger, you will find that the bad sound is gone.
那么这个声音到底怎么来的啊？老胡来给大家分析一下成因并提供解决方案吧！
So how does this sound come from? The old, to analyze the causes and solutions!
其实这个声音确实不是散热器本身发出来的，而是安装在墙上的挂钩！怎么回事呢？我们其实稍微有点物理知识就知道，铁（钢）是有比较明显的热胀冷缩效应的。所以在热水进入，散热器温度提高的时候，或者阀门关闭，水温随着散热器散热而下降的时候，散热器的物理长度就会发生微小的变化。此时，如果挂钩安装是做到垂直地面，且两个（或者三个）挂钩能在水平一条线上的时候，散热器与挂钩的刮蹭面积和刮蹭力会最小，此时很少会有声音。而如果其中一个挂钩安装不能做到垂直且一条线上，那么散热器与挂钩的刮蹭面积就会变大且刮蹭的阻力也会同时增大，这样当散热器受热或者冷下来发生长度轻微变化的时候，刮蹭的声音就来了。
In fact, this sound is not a radiator itself, but a hook installed on the wall. What's the matter? In fact, we have a little physical knowledge that iron (steel) has a more obvious thermal expansion and contraction effect. So when hot water enters, when the radiator temperature rises, or when the valve closes, and the water temperature decreases with the radiator cooling, the physical length of the radiator will change slightly. At this time, if the hook installation is perpendicular to the ground, and the two (or three) hooks can be on a horizontal line, the scraping area and scraping force of the radiator and the hook will be minimal, so there will be very little sound at this time. If one cannot do a vertical hook and line, then the radiator and linked to the scratch will be bigger and the scratch resistance will also increase, so when the radiator heating or cooling down time length varies slightly, the scraping sound came.
那怎么解决这个问题呢？最好的方法当然是找个负责任的安装师傅把挂钩调好。另外还有2个补救方法，其目的都与前者相同而且可以与前面提出的方法同时使用，就是最大程度的减少散热器与挂钩的刮蹭面积和刮蹭力。一种，是在散热器与挂钩接触的地方滴上润滑油，另外一种，是用淘宝上很容易买到的1mm壁厚的四氟管（又叫铁氟龙管PTFE管）剪小段，对半剪开，卡在散热器与挂钩的接触处。
So how do you solve this problem? The best way to do it is, of course, to find a responsible installer to put the hook up. There are 2 other remedies, which are all the same with the former, and can be used at the same time with the previously proposed method, which is to minimize the scraping area and scraping force of the radiator and the hook. A contact on the radiator and the hook on the local drop of lubricating oil, another is 1mm, it is easy to buy Taobao wall with the thickness of PTFE tube (also called Teflon tube PTFE) cut short, half cut, stuck in the contact radiator and hook.
整个世界，就一下子清静了……
