关于加热棒的使用心得

On the use of a heating rod

现在的加热棒都是控温加热棒，主要分三类：

The heating rods are temperature controlled heating rods, which are mainly divided into three categories:

一、双金属片控温加热棒

A, bimetallic heat control bar

就是我们最常用的加热棒，这是我们今天要讨论的重点。它是在热棒内部放置双金属片作为开关，利用双金属片的两面材料的不同，使金属片可以根据温度变化摆动，最终到设定温度时断开连接达到断电的目的。

This is the most commonly used heating rod, which is the focus we are going to discuss today. It is a switch in which two metal pieces are placed inside the hot rod, and the two sides of the two metal pieces are used to make the metal sheet wobble according to the temperature change, and the end of the wire is broken at the time of setting the temperature.

二、热敏电阻探测温度式加热棒

Two, thermistor detection temperature type heating rod

这是外控加热棒通常采取的工作原理。因为采取了热敏材料，对温度感应更加敏感，对温度的控制更加有效。

This is the usual working principle of the external heating rod. Because the thermal sensitive material is adopted, it is more sensitive to temperature induction, and the temperature control is more effective.

三、纳米加热片

Three, nanoscale heating sheet

貌似是市场上的新宠，主要被厂家以100瓦电=1000瓦热量给吸引了，在本文正题开始之前，本人先撕下这种伪科学虚伪的面纱。不懂科学没关系，假如100瓦电能发出1000瓦热量，我再把这1000瓦热量转化成1000瓦电，再用这个加热片，我将获得10000瓦热量，如此循环下去……不得不说，地球上不再需要能源了。有点物理常识的都知道能量守恒定律，所以这种产品无疑进行了虚假宣传，知情者应向有关机关报案，依法处置。

It seems to be the new favorite in the market, mainly by the manufacturer with 100 watts of =1000 watts of heat to attract, before the beginning of this article, I first tore this false false false face veil. Do not understand science, if 100 watts of electricity can send 1000 watts of heat, I will turn the 1000 watts of heat into 1000 watts of electricity, then this heating piece, I will get 10000 watts of heat, so circulate... It has to be said that energy is no longer needed on the earth. A little common sense of physics knows the law of conservation of energy, so this product has undoubtedly carried out false propaganda, and the informed person should report to the authorities concerned and deal with it according to law.

另外，关于纳米加热片也并非一无是处，符合科学的卖点就是不发光便发热，热效率比前两种都要高一些。

In addition, the nano heating film is not without merit, and the scientific selling point is that it will generate heat without lighting, and the thermal efficiency is higher than the first two kinds.

那究竟能高出多少呢？我们知道，电流经过电阻发热，当电阻热到一定程度到达发光的时候，电流产生的能量除了热量还有光能，光能中大部分会逸散到空气当中。我们不防观察一下我们的加热棒，1000瓦的加热棒的电阻丝的亮度，能不能达到1瓦的灯的亮度？显然不能！即使等于1瓦的亮度，那么纳米加热片也不过将热效率提高了千分之一而已。

How much can that be higher? We know that the current is heated by resistance, and when the resistance is heated to a certain degree of light, the energy produced by the current is in addition to the heat and the light energy, and most of the light energy will escape into the air. We do not want to observe the brightness of our heating rod, the resistance wire of 1000 watts heating rod, can we reach the brightness of 1 watts? Obviously not! Even if the brightness is equal to 1 watts, the heating efficiency of nanomaterials will only increase by 1/1000.

好了，不值得为伪科学浪费时间，言归正传。

Well, it's not worth wasting time on pseudoscience.

热敏电阻加热棒因为比金属片控温加热棒更精确，显然能在该开的时候开，该关的时候关，很多人都用上了变频这个词来形容。不得不说，这也是虚假宣传。何为变频？我们认为变频加热棒是能根据缸内的温度变化而调整功率的加热棒。

A thermistor heating rod is more accurate than a metal sheet, apparently able to open when it is open, and when it is closed, many people use the word "frequency conversion" to describe it. It has to be said that it is also false propaganda. What is frequency conversion? We think that the frequency conversion heating rod is a heating rod which can adjust the power according to the temperature change inside the cylinder.

说到这里，很多人要拿变频空调说事了，的确，变频空调也不是变频，也是虚假宣传，并非恒温就是变频，恒温的办法有很多种，变频只是其中一种比较高级的罢了。而变频不易做到。

Here, a lot of people want to take frequency conversion air conditioning things, indeed, frequency conversion air conditioning is not frequency conversion, but also false propaganda, not constant temperature is frequency conversion, constant temperature method has many kinds, frequency is only one of the more advanced. And frequency conversion is not easy to do.

那么无论何种加热棒，从水体温度而言，能够稳定恒温就是最节能的加热棒了。说到这里，很多人大概已经不耐烦了，既然都不节能还废话，直接上热敏电阻加热棒不就行了？还有脸申请加精？

No matter what kind of heating rod, from the water temperature, the constant temperature is the most energy-efficient heating rod. Speaking of this, many people are already impatient. Since they are not saving energy, they will not be able to heat the rods directly. And face application for refinement?

好吧，前期的铺垫只是陈述一个观点，能够稳定恒温就是最节能的加热棒，而热敏电阻受制于热敏材料的质地，达不到理想程度，所以就此推导出一个结论，能够根据温度变化自动调整功率的加热棒才是最节能的加热棒！

Well, the early paving is just a point of view that can stabilize the constant temperature is the most energy-saving heating rod, and the thermistor is subject to the texture of the thermal material, which can not reach the ideal degree. Therefore, a conclusion is deduced that the heating rod that can automatically adjust the power according to the temperature change is the most energy-saving heating rod!

虽然这种加热棒原理也简单明了，也能够制作出来，但也需要多次设计、试验，成本一时下不来，最终也未必便宜。

Although the principle of this kind of heating rod is simple and clear, it can be made, but it also needs to be designed and tested many times. The cost is not coming for a moment, and it is not necessarily cheap at the end.

在这里我推荐鱼友使用一个土办法，我称之为三段式变频控温。现在回到开始，双金属片控温加热棒，我第一段里就说过这是我们讨论的重点。

Here I recommend the fish friend to use a soil method, which I call the three stage variable frequency temperature control. Now back to the beginning, bimetallic temperature control heating rods, I said in the first paragraph, this is the focus of our discussion.

根据鱼缸水体计算需要的加热棒功率，假如根据计算得知需要800瓦的加热棒，图省事的人选了800瓦的，有心机的选了两根400瓦的、他怕停电，这里我建议选择500瓦、200瓦和100瓦。

According to the water tank water calculation required heating rod power, if according to the calculation that the need for 800 watts of heating rod, the figure to save 800 watts, the heart machine selected two 400 watts, he was afraid of blackout, here I suggest to choose 500 watts, 200 watts and 100 watts.

选好加热棒就该考虑控温区间了，用过这种普通加热棒的人都清楚，他可能存在1度左右的误差，这也是它不如热敏电阻节能的原因。

A heating bar should be selected to consider the temperature control interval. People who have used this ordinary heating rod know that he may have an error of about 1 degrees, which is not the reason why it is not as efficient as the thermistor.

假如我们需要30-32度，选800瓦的人直接会设31度，选两个400瓦的其实很多人没有考虑到，除了防止停电，还多了一种可以设置不同温度的选择，通过温度差而使两者处于不同工作状态，当两根加热棒仅有一根在工作时，恒温效果会明显好于单独用800瓦的缸，节能也更明显。

If we need 30-32 degrees, 800 watts of people will set up 31 degrees and two 400 watts. In fact, many people do not take into account that, in addition to preventing power outages, there is a choice to set different temperatures, and the two are in different working conditions through the temperature difference. When only one of the two heat rods is working, the temperature effect is constant. It will obviously be better than using a 800 Watt cylinder alone, and the energy saving is more obvious.

下面我重点讲解500瓦、200瓦和100瓦的三段式变频控温。

Next I will focus on the three stage variable frequency temperature control of 500 watts, 200 watts and 100 watts.

更好的使用加热棒，一定要考虑鱼缸所处的环境，极端冷是不需要变频的，极端热是不需要加热棒的。以我们普通的北方家庭为例，全年室内温度在16-28度，以每年4月中旬停暖之后和11月中旬供暖之前最冷。

Better use of heating rods, we must consider the environment of the fish tank. Extreme cold does not require frequency conversion. Extreme heat does not require heating rods. Take our common northern family as an example. The indoor temperature is 16-28 degrees throughout the year. It is the most cold before heating in mid April and mid November.

我们可以将100瓦的加热棒设置为31.5度，将200瓦的加热棒设置为31度，将500瓦的加热棒设置为30.5度。这个设置基本上保证了100瓦的棒子一直处于工作状态，在室内温度25度以上时，仅有此加热棒工作即可完成恒温，温度一天变化不会超过0.5度。

We can set the heating rod of 100 watts to 31.5 degrees, set the heating rod of 200 watts to 31 degrees, and set the heating rod of 500 watts to 30.5 degrees. This setting is basically guaranteed that the 100 - watt rod is always working. When the temperature is above 25 degrees, the thermostat can be completed only by the heating rod, and the temperature will not exceed 0.5 degrees a day.

当室内温度在20-25度左右时200瓦的加热棒开始工作，这时候有300瓦的加热棒在工作，实际温度一般会稳定控制在30-31度，温度稍高第二根棒就停止工作，第一根棒还在100瓦的功率工作着，延长了降

When the indoor temperature is around 20-25 degrees, 200 watts of heating rod begins to work. At this time, there are 300 watts of heating rods working, the actual temperature is generally controlled at 30-31 degrees, the temperature is slightly higher and the two rod stops working, the first rod works at 100 watts, extending the drop.
