Reveal the mysterious veil of the thermal tube

Now the wind and cold heat dissipation facing the high -end DIY market has been completely occupied by thermal pipe products. Without 4 pipes, 8 pipes make people look like a high -end domineering feeling. The fins of the copper are really shocking. But behind the gorgeous, do you really know the heat tube?

The heat pipe seems to be similar, usually copper pipes. Some manufacturers add some electroplating processes to prevent copper oxidation, and also give heat dissipation products a more beautiful color matching. But, is it the same heat tube with the same heat dissipation effect? The answer is obviously not. The seemingly the same bronze skin is not a cave. The internal structure is very different, and there are certain differences in cost and heat dissipation effect.

The key to heat the heat pipe is on this tube. What should consumers go when they buy, is it cheap or efficient? Can you find a cost -effective choice between the two and avoid various cottage products in a timely and effective manner. Let's open the heat tube and explore what is different in its internal and what kind of heat tube is a good hot tube!

The principle of thermal pipe work and the structure of thermal slag

The thermal tube consists of tube shell, suction liquid core, and end cover, and pump into the tube into 1 · 3 × (10 losses, 1--- 10 losses 4) PA's negative voltage of PA is charged with an appropriate amount of working liquid to make the inner wall of the tube close to the inner wall of the tube. The liquid -absorbing core hair is sealed and sealed after the liquid is filled. One end of the tube is the evaporation section (heating section), and the other end is the condensed section (cooling section). According to the application needs, the thermal insulation section can be arranged in the middle of the two sections. It makes full use of the rapid thermal transmission properties of the thermal conductivity and the cold medium, and quickly transmits the heat of the thermal object to the thermal source through the thermal pipe, and its thermal conductivity exceeds the thermal conductivity of any known metal.

Thermal pipe work principle

The liquid in the tube absorbs heat and evaporates in the endothermic section, and condenses and refluxes in the cooling section, and the heat is taken away by circulation. But the efficiency of this process is determined by the material and manufacturing process of the wick in the heat pipe.

Hot slag structure

Internal structure of thermal pipe

The production process of this structure is to heat the copper powder to a certain temperature. Before it is not fully melted, the edge of the amount of copper powder granules will be melted first. Inner wall structure. But the difference is that this inner wall structure is very hard and like metal. The production cost of this heat pipe is higher.

The groove structure of the heat pipe heat dissipation form

This processing method is to process many small slots in the inner wall of the heat pipe. These grooves are like capillary blood vessels, and they also generate certain suction power to accelerate the rapid return of liquid in the tube.

Found accuracy affects the effect greatly

However, according to the precise and delicate situation of the slot, according to the process level of the process and the direction of the groove, it will have a great impact on the heat dissipation of the heat pipe. The finer the groove, the faster the reflux speed of the liquid. Generally speaking, the processing method of this heat pipe is relatively simple, difficult, and the price is relatively cheap. Similarly, its effect is not as good as the hot slag heat pipe.

Multi -metal mesh in the form of heat pipe heat dissipation

This design is attached to the inner wall of the copper pipe similar to a weaving bag. Generally speaking, it is copper. There will be a gap between the preparation of the metal wire, which will generate a certain suction power to accelerate the return of liquid in the tube to a certain extent.

Simple structure and performance

The production process of this heat pipe is the simplest. As long as a copper tube that can resist negative pressure, plus some metal nets. The cost is relatively low, and its heat dissipation effect is not as good as the previous two. It is used by most heat pipe radiator.

Domestic cottage style in the form of heat pipe heat dissipation

Many readers estimate that they are wondering when they see this name, but the facts that really exist. Now that this article is written, the author will be directly clear here. Fake heat pipes exist!

Fake thermal pipe

With the above picture, you can simply summarize the production process of cottage fake goods. Pull the liquid and seal the liquid of alcohol in the copper tube. There is no suction core on the tube wall to return the liquid back. Unless the heat dissipation effect of this heat pipe is very strong, the liquid in the inside is basically not circulated, and the heat conduction effect is very poor.

Article summary：

A new round of competition is about to start the cooling products. In the face of the current popularity of heat pipes, the effect of more heat dissipation is not necessarily good, but it depends on the structure of the thermal pipe and then concluded. In addition, after the heat pipe is bending and other deformation operations, the core structure of the liquid absorption will change to a certain amount. The cottage products of the dragon flying phoenix dance will not have a good effect even if they use real thermal tubes. The heat dissipation effect of the heat pipe also depends on the pipe diameter. Generally speaking, buying thick and not fine.

Although the four thermal pipe structures are mentioned in this article, the effect is decreasing in turn, but the heat scum -type heat pipe is generally only common in high -end heat dissipation products, and its price is relatively high. Most of us are grooves or metal mesh types. When you choose, while taking into account the cost -effectiveness, try to consider the overall effect of heat dissipation products, instead of making a lot of money in tube.

Although it is an article with popular knowledge, the relationship between heat dissipation and heat pipes, many players think that the heat dissipation effect of buying multi -heat pipes will be good, but it may not be real. The number of thermal pipes is not proportional to the heat dissipation effect, but it is more related to its workmanship.
