Electrical gadgets generate some heat that normally takes place upon the execution of the circuit to provide power. In most cases, some of the high power semiconducting devices also have a tendency of generating considerable amounts of heat. Even though this is the case, their ability to dissipate heat tends to be inadequate due to their low capability. As a result, most of these gadgets fail prematurely and it may have negative effects on the entire system. To manage this problem, appropriate heat sink technology has come into use.
What is a heat sink?
A heat sink is an electronic device of an electric circuit designed to dissipate heat generated by electronic devices passively. This device creates optimal temperatures for the device to operate by regulating heat levels. Heat sinks are common in semiconductor devices such power transistors where they create moderate temperature conditions for the device to function. In effect, this boosts performance and reliability that may be compromised by premature failure.
Heat sinks operate using Fourier’s law of conduction. This law simply states that upon the existence of a temperature gradient within a body, there will be heat transfer from a region of high concentration to a region of low concentration. Heat transfer, in this case, is achieved in three primary ways that include radiation, convention and conduction.
Objects with high temperature levels often transfer heat by means of conduction when they collide with objects with low temperature levels.In a similar fashion, heat sinks transfer heat from highly concentrated areas to low concentrated medium like oil, water and air. Air is mostly preferred as a medium of low temperature.
There are various types of heat sinks in the market today. These sinks come in a variety of categories based on particular criteria. In this article, we shall only mention two major types, which are the active heat sinks and the passive heat sinks. Active heat sinks come fitted with fans or a blower. Some of the most common ones include the ball bearing fans. They provide efficient performance because of their moving parts. On the other hand, passive heat sinks do not have any mechanical components. These ones utilize conventional heat dissipating methods. Because of lacking moving parts, they are considered more reliable in the market.
Even though heat sinks are available in the market, some people prefer the option of homemade heatsink. The question that arise with this sinks is, how can make their own homemade heatsink? In the next section, we are going to look at steps of making a heatsink from your home.
How to make a homemade heatsink
When thinking about making homemade heat sink, let us look at the list of items you need to have when working on your own heat sink. You need to have a hammer, iron cutting hand blade, useless choke of a tube light that you can get from scrap, glue, a screwdriver, a big sand paper and an iron cutting hand blade. With these items ready, you stick to the following steps.
Step 1: Aluminum base
You need either aluminum or copper base because they have the capacity to dissipate heat much faster when compared to other metals such as iron. Next is to attach them to the LED. Using the hammer, gently straighten the angles by stroking them gently. It is preferable to have a thickness of at least 2mm. cut a piece of 1 by 1 inches.
Step 2: LED attachment
This is where you use the super glue to attach the LED to the aluminum. Super glue is a preferred choice because comes with less viscosity and dries faster compared to other options. Also, super glue makes very thin layers and it is a good conductor.
Step 3: Get the iron strips
At this stage, get the old choke from tube light. It has many wrought iron strips that one can access using a screwdriver. Even though iron is not a good conductor compared to aluminum, you can still use it at this stage because of the increased surface area. This will also serve the role of heat dissipation quite well.
Step 4: Get the strips clean
When retrieved from scrap, most of these strips are usually rusty. Clean them using sandpaper. This is followed by applying glue to their respective centers. For effectiveness, use five strips. During this process, it is advised that you place them in an overlapping manner turning at different angles.
Step 5: Light the LED
You can check it at about 4 volts for an hour. You will realize that it works just fine because of the constant temperate maintained by the homemade heatsink.
Well, putting your knowledge and skills to use can be quite exciting. While this is the case, it is advisable to consider quality heat sinks. Getting a good heat sink from a reputable manufacturer gets the job well done. We take pride in the type of heat sinks we manufacture because they come with the following benefits. They are equipped with high and efficient thermal conductivity properties that promote performance. Our heat sinks are light and handy making them ideal to boost system efficiency.
Secondly, depending on the type of electrical gadgets, whether industrial or at home, our heat sinks are popular thermal conductors. They have high strength metal properties convenient for metal heating. Furthermore, they are friendly to handle and easy to install. Our LED heat sinks come in various shapes and sizes with aesthetic qualities. Due to this, they can fit in any location without interfering with the ambience.
In conclusion, when it comes to choosing heat sinks, think no farther. Our company has state of the art heat sinks that are both durable and lasting. When searching for heat sinks, make sure that you go for the appropriate sink designed to address your requirements. If you are not sure about the type of heat sink you need, then you can contact us.
