THESE HEATSINKS MAY HELP

Although the term laptop heat pipe  may not be what most people think of when they hear the word computer, exactly. Without heat pipe technology inc , modern computers couldn't run at the speeds on their regular basic .   Just as you cool down with a cold bottle of Gatorade after a high impact workout, heat sink also  dissipates the heat of  your computer's processor after it runs multiple programs simultaneously. And if you don ’ t have  a qualified  heat sink, your computer processor may be  overheating, which could destroy  the  entire system, costing you lots of money and energy .  Thus, having a  custom heatsink  will be a nice chioce.   But the question is what exactly a heat sink  is  and how it work s ? Simply speaking ,  heat sink  is an object that disperses heat from another object. They're most commonly used in computers, but also found in  cell phones , DVD players and even refrigerators. In computers, a heat sink is an attachment for chip  heatsink  that pr

This is how chip cooling works

In the early days of computers, there weren't many computer components that used large heat sink . With the increasing power of computers and prevalence of overclocking among computer players, modern computers have increasingly high requirements for the heat sink  of important components.  Methods of heat-dissipating are various , basically divide d  into air cooling,   chip heat sink ,   water cooled plate  and so on. The commonly used   one--- air cooling, in fact, is heat sink fins  with  good thermal conductivity tightly against the larger chip .   A bove the heat sink   there is  a small fan.   In this way, the airflow generated by the high-speed rotation of the fan takes the heat away from the fins. P ay attention to  these points when choose air cooling: R egardless of the material problem, I believe there are  still many people think that ,  the larger the size of the heat sink  is , the better the heat dissipation effect can play. In fact, the quality of heat sink has n

Where can’t copper heat sinks be used?

Copper heat sink  has its advantages, also have its disadvantages. As is often the case that distributors and manufacturers always introduce advantages of heat sink while the disadvantages are hardly mentioned. However those shortcomings are often the key to solving the heat sink problems. Large heat sink   has great demand for water quality of heat -supplying  system . I f it has a simple corrosion phenomenon   in the unsafe heating system, chip heat sink  manufacturers said that consumers should know whether the heat sinks match the residential  heat-supplying system before their purchase. Since  water quality  of those  residential  heat-supplying system  can not reach the specification, recently  companies have begun to take  corresponding anti-corrosion measures.

What opportunities and challenges does the aluminum heat sink industry face?

This has been a tough year for the   heat sink s   suppliers .  Large  heat sink  industry in the war on the battlefield, the future is the battle of soft power.   The strong will grow stronger, and the weak will fade away.   Now those predictions are coming true.   Fixed aluminum heat sink  market rise is weak, in the early stage of change, the performance of aluminum heat sink  companies slow down the trend.   At the same time, the changing environment at home and abroad has put the company under unprecedented pressure to survive. First, the growth rate is slowing down Data show that even though the market for heat sink s   aluminum  in China  is still growing steadily, the overall upward trend has slowed down significantly.  A luminum heat sink  on the market up slow, the company up drive is insufficient.   While the cost of heatsink  materials  and labor continued to increase, the price of aluminum heat sink  continued to decline, resulting in the compression of the profit ran

How to effectively prevent the false warranty of heat sink?

Extrusion technology makes a better heat sink

A luminium extrusion heatsink   must  have extremely high requirement on shape design and dimensional accuracy .   Plus, round aluminum heatsink   should have no  error in molding process  to  achieve the best heat dissipation effect , which means  the help of technology of aluminium heat sink  is indispensable. Extrusion molding is to put in the mold cavity of the alloy material to exert a strong pressure  making  the aluminum alloy directional deformation . And then  obtain the proper  section shape, size and certain mechanical properties of the parts processing method.   Using   heat sink extrusion  technology can make   heat sink  of high precision, good surface quality and the solid  structure, which e nsure the pass rate of our products.  However, t he traditional welding technology is not as  good as extrusion molding.   It doesn’t  meet the accuracy  demand  and easy to rot,   which  affect s  the stability of the whole structure.

How to improve the utilization of high power led heatsink?

While using  LED heat sink , how to improve its  efficiency, especially when we  use high power led heatsink .   Here below are  relevant instructions. The heat sink  temperature control valve is installed on the automatic control valve.   Its control elements are temperature-sensitive materials filled with temperature control components. When the temperature rises, the temperature pack expands to make the valve smaller, reducing the hot water supply to the aluminum heat sink for led . If  the temperature drops, the situation is reversed, thus the purpose of temperature control   achiev e .   The LED heat sink  temperature control valve can also adjust the set temperature and automatically control and adjust the hot water supply of the LED  light heat sink  according to the set requirements.  Luckily,  LED heat sink  temperature control valve with built-in preset device solves this problem.

Fin design of round aluminum heat sink for led light

The round aluminum heat sink  is designed as a sunflower  shape  and fin shape , not only  to increase the contact area with the heat source absorb ing  more heat, but also increase the contact area between heat sink in  led lights  and air in order to disperse heat to the air more quickly. Here people may  wonder if the thicker   fins  are , the better cooling effect will be . Absolutely not , the round heat sink  of the whole area is finite .   Thus, more   fins means   that there ’ re  more contact area s  to absorb more heat, but it also means that the spacing  between the fins is shorter.  the air flow velocity of each channel  is slower as well , which   results in difficult y of dispersing heat to the air.

How to produce a led light heat sink with good cooling effect?

Heatsink for led  as a high heat dissipation efficiency of a heat dissipation tool, different LED heat sink manufacturers master different technologies, the production standards are different, the led light heat sink produced in the heat dissipation effect will have advantages and disadvantages. So how can LED heat sink manufacturers produce a good cooling effect led light heat sink? Heat sink bottom thickness design. Many people in contact w ith the led light heat sink   will think that heat pipe fin  is the key to heat, in fact, the bottom of the heat sink is a part of the heat can not be ignored. The led lighting heat sinks  should adhere to the principle of being thinner from the heat source part to both sides on the bottom design, which is to ensure that the heat absorbed by the heat source part can quickly transfer to the surrounding thinner part. And then achieve high efficiency heat dissipation. If bottom heat sink is designed level off, the heat of heat source part diffuses

Where should the heat sink be installed in the computer?

The iron thing under the CPU fan is the  CPU heatsink . Computer heat dissipation is actually the process of heat transfer, the purpose is to bring the heat generated by the CPU to other media, to control the CPU temperature in a stable range. Depending on the environment we live in, the heat from the CPU is ultimately released into the air. And the heat transfer process is the role that heat sink should play. Heat convection is the main way to heat to cool the  500w heat sink . According to the different means of heat conduction and heat convection, heat sink products can be divided into active and passive ways. Active means that there are energy sources unrelated to the heating element involved in forced cooling, such as fans, pumps in  liquid cooling , and compressors in phase-change refrigeration. These cooling methods are generally characterized by high efficiency, but they also require the assistance of other energy sources. Passive, on the other hand, means simply relying o

How can we deal with heat sink with dust?

With the extension of computer use, there’re a lot of dust and stains in the   Cpu heat sinks  . And what’s more, the Cpu power supply will severely pile up lots of dust and stains, which can lead to high temperature of CPU. Abnormal computer will also take the initiative to duplicate the downtime,etc. In order to completely eliminate contamination of computer CPU heat sink and fan, we should let CPU electronic   heat sink   fins  and metal to be completely separated using common household cleaning fluid and oil brush to completely remove   copper heat sink . Inserting the heat sink matrix is to further improve the performance of heat sink matrix to another level. For most of the existing microprocessor applications, like electronic components,their exposed surface area is actually much smaller than heat sink substrate surface area. This situation lead to hot pressing substrate of  non-isothermal  distribution on the whole area.

Power batteries have higher technical requirements for general batteries and higher requirements for the sustainability of batteries. At present, power battery manufacturers are everywhere in China, seemingly it has developed comprehensively as well as  heat sink manufacturers . Power battery pack  liquid cooling heat sink   experts believe that power battery pack industry will be from everywhere to the situation of polarization, on a period of time, power battery enterprise polarization is significant. Seems we should pay some attention to the  large heat sink . Throughout the development of domestic power batteries, the rapid expansion of battery capacity led to the overall domestic lithium battery will continue to excess. From the quality point of view, there are more low-quality production capacity and still lack of high-quality production capacity. The concentration degree of power battery industry will be furth

How heat sink fin gap works in natural cooling?

  Heat sink technology includes different kinds of heat sink. Such as   skived fin heat sink s , heat pipe heat sink,   led heat sinks  and so on. Here we’re talking about the gap of heat sink fin. As usual in thermal engineering quite bit quite meets the attention . The fin gap of a heat sink, if not optimized for your application, can actually reduce the thermal efficiency of your heat sink. If the fins are too narrowly place then the channel is just too narrow and air features a harder time getting through! Think of air because it really is: a fluid. Don’t forget that in physics, a fluid are often either liquid or a gas. That should help you to visualize what’s going on.    The project we were working on was for a rather  large heat sink , for a wireless network remote radio head (RRH) application. The customer was another Telecommunications Equipment. The customer actually had developed their own conductor for  natural cooling . While the planning was basically on track , the th

Hybrid 1-piece Vapor chamber

Single-piece integrated VC costs less than two-piece VC, maintains the same thermal performance characteristics, and adds some unique features.Single-piece VC, like heat pipes, is in direct contact with a heat source and has multi-direction heat flow.But they are cheaper to produce because they are simple and require fewer tools. The design steps Step 1: first determine the location In view of these limitations, the focus is on the heat sink  itself. First of all, we should know whether the condenser is away from the heat source or close to the heat source. ·  If the distance is more than 40-50mm, heat pipe   heat sink is better. The design is highly flexible, allowing for bending  and flattening to conform to any shape in the three dimensions. ·  If the focus is on solving the diffusion thermal resistance, then the VC heat sink   scheme is the best, but the basic condition is that the perimeter ratio of the heat sink   to the heat source is greater than 30:1. Step 2: si
