Is the quality of steel heat sinks good? What materials are made of heatsinks

Steel Heat Sink: Advantages, 1Strong pressure resistance 2

Easy to install and maintain 3The appearance is also more beautiful 4The cost is relatively moderate, and the foreign application is relatively large.

5.The way of convection is more comfortable, and the thermal efficiency will be higher. Cons:

1.It will cause corrosion because of the oxygen integrated into the water, and the water of the heating system is oxygen-rich tap water, and most of the domestic radiator pipes have serious corrosion problems because they do not take oxygen blocking measures (St. Lawrence radiators imported from Europe effectively use oxygen blocking measures to prevent corrosion problems), resulting in a relatively high frequency of water leakage accidents. (But most families will not use it for hundreds of years, so it is more important to consider steel) 2

The weight of the steel radiator plus the weight of the water is still much heavier than that of aluminum. A test of the material of the installation and hooks.

In general, if your house is going to live for a long time, and the local heating water quality is not very good, it is recommended to buy a copper-aluminum composite radiator, of course, this will be more expensive. If you prefer steel radiators, try to keep them full of water when not in use. At the same time, the return valve must be added to prevent quality problems, which cannot be repaired or cause greater property losses.

1. Aluminum extruded heat sink.

Due to the soft and easy processing characteristics of aluminum material, it has been applied to the radiator market for a long time, and the aluminum extrusion technology is simply to put aluminum ingots.

After high temperature heating, the molten aluminum is allowed to flow through an extrusion die with grooves under high pressure to make the primary embryo of the heat sink, and then the primary embryo of the heat sink is cut and grooved to make a common heat sink.

The cost of aluminum extruded heat sink is low, and the technical threshold requirements are not high, but due to the limitation of its own material, the ratio of the thickness and length of the heat sink can not exceed 1:18, so it is difficult to increase the heat dissipation area in a limited space, so the heat dissipation effect of aluminum extruded heat sink is relatively poor, and it is difficult to be competent for today's rising high-frequency CPU.

2. Plug copper heat sink.

The main materials used in the mainstream heat sink in the market are nothing more than aluminum and copper, and the copper plugging process is the product of combining the respective advantages of aluminum and copper.

The copper plugging process is the use of thermal expansion and cold contraction.

The aluminum extruded heat sink is heated and the copper core is plugged into it, and finally the overall cooling is carried out.

Since no third-party media is used, the copper plug process can significantly reduce the thermal resistance between the contact surfaces.

It not only ensures the tightness of the copper-aluminum bond, but also makes full use of the characteristics of fast heat dissipation and fast heat absorption of aluminum. This copper plugging process has a moderate cost and good heat dissipation effect, and is the mainstream heat sink type on the market.

3. Pressing method.

That is, a large number of copper or aluminum sheets are superimposed, and then pressurized on both sides and polished with a section that is in contact with the CPU core and the other side that extends as a fin for the heat sink.

4. Forged heat sink.

The forging process is formed by heating the aluminum block and using high pressure to fill the mold, its advantage is that the height of the fin can reach more than 50mm, the thickness is less than 1mm, and the maximum heat dissipation area can be obtained in the same volume, and the forging is easy to get good dimensional accuracy and surface finish.

However, during forging, due to the low plasticity of the metal, it is easy to crack when deformed, and the deformation resistance is large, and a large ton (more than 500 tons) of forging machinery is required, and the product cost is extremely high because of the high cost of equipment and molds.

4. be quiet!: The brand focuses on the manufacture of high-performance silent computer hardware, and its heatsink is well balanced in terms of heat dissipation, while also effectively reducing the noise of the fan.

The above brands have a certain degree of popularity and recognition in the field of electronic equipment, and are suitable for different types of computer hardware equipment. When selecting a heatsink, it is recommended to evaluate and select it according to factors such as device model, functional requirements, and price point, and pay attention to follow the manufacturer's instructions for use and installation to ensure its safety, stability, and excellent heat dissipation performance.

Installing a home heating system is now a common consideration before renovating a home. We can choose a household boiler that we are satisfied with, but we are often overwhelmed by the choice of the heating end and choose the heating method. It is more reasonable to use radiators to dissipate heat, and it is more ideal to choose steel plate radiators for radiators.

1. Good thermal workability.

Steel radiator can be a good solution to the problem of indoor temperature uniformity of other radiators, because only steel plate radiators can obtain good thermal performance, that is, 30% radiation heat dissipation, 70% convection heat dissipation, so as to obtain the highest thermal comfort, if the radiation heat dissipation is too large to cause damage to the indoor furniture surface, the indoor heating speed will also slow down, and the heat loss is large. Of all the radiator types, only steel panel radiators can achieve high convection heat dissipation.

2. It has good corrosion resistance.

Many people are worried that steel panel radiators will corrode, in fact, this is a misunderstanding of radiators, because in the independent heating system of the home, the water flow is closed, completely isolated from the air, and there is no oxygen in the water. The main corrosion of steel is oxygen corrosion, if the water system has no oxygen, how can there be corrosion. On the contrary, many people think that aluminum is corrosion-resistant, but it is only resistant to acid corrosion, and the heating system is often neutral to alkaline, especially the centralized system, the corrosion of aluminum radiators is very serious, and the electrochemical corrosion of aluminum alloy is also the most obvious in the heating system, which is the main reason for the perforation and corrosion of aluminum alloy radiators.

3. Beautiful appearance.

It is in good harmony with the interior decoration, and the milky white surface color is the easiest to integrate with the wall, and the elegant shape design integrates functionality and decoration. The surface of the radiator is treated in strict accordance with the unified European environmental protection standards, after cleaning and passivation, anti-corrosion, and finally electrostatic powder spraying and drying, to achieve the perfect effect of long-term anti-corrosion.

4. Energy saving and comfort.

When the temperature valve changes, the steel plate radiator can respond quickly, shorten the transition time, control the temperature accurately, and save energy.

5. High thermal efficiency and fast heating rate.

The heat dissipation efficiency of steel radiators is the highest among all forms of radiators (about 4 times that of cast iron radiators), and the best heat dissipation effect is achieved with a smaller volume, and the heating hood is no longer needed, minimizing the occupancy of indoor space and improving the utilization of the room. Due to the small water storage capacity of steel plate radiators, the boiler heats up quickly, the indoor heating is also fast, and the thermal inertia is small.

The heat sink material refers to the specific material used in the heat sink. The thermal conductivity of each material is different, and it is ranked from high to low in order of thermal conductivity, which is silver, copper, aluminum, and steel. However, it would be too expensive to use silver for the heat sink, so the best solution is to use copper.

Although aluminum is much cheaper, it is obviously not as thermally conductive as copper (about 50 percent of copper).

At present, the commonly used heat sink materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is more expensive, difficult to process, too heavy (many pure copper heat sinks exceed the weight limit of the CPU), small heat capacity, and easy oxidation. The pure aluminum is too soft to be used directly, and the aluminum alloy used can provide sufficient hardness, and the advantages of aluminum alloy are low and lightweight, but the thermal conductivity is much worse than copper.

Some radiators take their own strengths and embed a copper plate on the base of the aluminum alloy radiator.

For ordinary users, the use of aluminum heat sinks is enough to meet the heat dissipation needs.

The most commonly used materials for heat sinks are copper and aluminum profiles. The thermal conductivity of copper is good, and the heat dissipation effect is relatively good, but it is high;The thermal conductivity of aluminum is low, and the heat dissipation effect is also lower than that of copper

The heat sink needs to improve the heat dissipation efficiency, you can use the nano carbon heat sink spraying material of Liwang new materials, and the heat dissipation efficiency of copper and aluminum heat sinks can be increased by 15% and 25% after use.

Due to the very good thermal performance of copper and aluminum, the heat dissipation capacity of steel radiators is much higher than that of radiators of other materials, and its heat price ratio is much higher than that of radiators of other materials. And because copper and aluminum are non-ferrous metals, its value is growing over time, so the value retention rate of steel radiators is much higher than that of radiators of other materials. Aluminum alloy can be extruded into various shapes, so the appearance of steel radiators can be varied to meet the consumption concepts of different consumers.

Steel radiators, because of their outstanding anti-corrosion performance, general suitability to cherry blossoms, good heat price ratio, high value retention rate and beautiful appearance, will become the leading new type of radiator for a long time in the future. The market prospect is also very broad, with the steel radiator from time to time pause and promote the use of it will play a greater role in the industry pause.

The radiator is directly affected by the market, and the radiator on the market is high, and every brand will not be cheap. For these special shopping festivals such as Double 11, merchants will also give discounts** and launch preferential policies, and users should seize this stage to enjoy more discounts.

How much does it cost to install a radiator? There is a simple way to calculate, to see how much is the actual usable area of a family room, we take a house of 100 as an example, the usable area is assumed to be 80, if you can install a steel radiator, we temporarily select a steel 80 * 35 model, it is 600mm high each piece with a heating area, divide by 80, a total of 43 pieces, multiply the number of pieces needed by each piece, is about the amount of money that needs to be spent.

Any model of radiator can be calculated in this way. However, when actually purchasing, considering that there are elderly and children at home and the heat preservation and heat loss of the room, you can consider that one or two more pieces can be installed in each room. Purchase and install at the right time, the calculated price must be inexpensive and affordable, spend less money, so that the family can have a warm and secure winter, which is also a great achievement.

Different brands of radiators, production processes, after-sales service are also different, these factors will also indirectly affect the life of radiators. Some small workshops of miscellaneous radiators, after a few years of use, there will be problems such as radiators not hot, water leakage, etc., and there is no after-sales service to deal with, in comparison, it is the products of large enterprises that are more reliable, although the highest is higher, but the quality is more guaranteed, labor-saving and worry-free.

If the radiator is not purchased properly, it will not only affect the heating effect, but also cause losses to family property, so how to choose the right radiator. When purchasing radiators, you can refer to the ranking of the top ten brands of radiators:
