Every electrical and electronic module in a circuit generates some amount of heat while the circuit is executed by offering the power supply. Most of the high power conducting devices like the power transistors and the
Most of the high power conducting devices like the power transistors and the optoelectronics like the Light emitting diodes and the lasers are also generating the heat in the considerable amount.
However, these kinds of the components are inadequate to diffuse the heat energy, because their capability of dissipation is very low. Due to these heating problems, the electrical and electronics products are heading to the premature failure.
This failure may crash the entire circuit of the system’s performance. So, the temperature should be eliminated or reduced from the device to avoid these problems. For this purpose, the heat sinks are used in these kinds of the appliances for cooling. In this article, you will see what is a heat sink in

What do you know about the heat sink?
In general, the heat sink is a kind of the electronic component or the device which resides in the electronic circuit. It can help to disperse the heat from the other parts especially from the power transistors of the circuit into the surrounding medium. Then, it can cool the components easily by transferring the heat energy to the air. In fact, having
Then, it can cool the components easily by transferring the heat energy to the air. In fact, having a heat sink in the electronic device can help to avail the features that are presented as follows.
- The heat sink can help to increase the device’s efficiency
- It can improve the reliability and performance.
- It can also avoid the premature failure of the device’s components.
In this way, the heat sink offers the wonderful feature in reducing the heat energy of the electrical device. You can see what is a heatsink in the easiest manner.
Importance of the heat sinks
The heat sink is the passive heat exchanger which is structured to have the large surface are in contact with the surrounding medium like the air. It can maintain the thermal stability in a controlled way for each kind the electronic and electrical components.
However, the performance of the heat sinks always depends on upon some interesting factors like as follows.
- Design of the heat sinks
- Air velocity
- Surface treatment
Of course, these kinds of the things are determining the performance of the heat sinks. If the heat sink is not placed in the electronic circuits, then, there are possible chances to get the failure of the parts as mentioned as follows.
- Power transistors
- Integrated chips
- Voltage regulators
- Light emitting diodes
Certainly, the absence of the heat sink in the device may cause the crashes in all these components. So, it is recommended to use the heat sink in the device to avoid the overheating problems.
For this reason, the heat sinks are used in the variety of the electrical and electronic devices like as below.
- Desktop and personal computers
- Mobile phones
- DVD players
In this manner, heat sinks are used in the variety of applications to improve its reliability and the performance. You can get to know what is a heat sink easily.
Major types of heat sink
Normally, the heat sinks are classified into the variety of categories based on some factors. However, the major types of the heat sinks are,
- Active heat sinks
- Passive heat sinks
In fact, the active heat sinks are available in the general fan type and it can utilize the power for the cooling. So, they are also called as the fans or the simple heat sinks. This type of the active heat sinks are further categorized into the two groups and they are,
- Ball bearing type
- Sleeve bearing type
Here, the ball bearing type of motor fans is preferred to use mostly, because they are cheaper and long lasting. Then, the sleeve bearing type of the motor fans is used for the long-term applications and so it is quite expensive to use.
The passive heat sinks do not have any mechanical parts and they are made up of aluminium finned radiators. This type of the heat sinks has used the convection process to diffuse the thermal energy from the device. So, it is highly reliable than the active heat sinks.
These passive heat sinks are highly recommended to maintain the continuous air flow across the fans.
Some other kinds of the heat sink
There are some other types of the heat sinks are available in the market and each of them has offered the unique features and benefits in improving the performance of the electrical device. In that manner, some of the types of the heat sinks are listed as follows.
- Aluminium heat sink
- Stamped heat sink
- Machining heat sink
- Bonded fin heat sink
- Folded fin heat sink
- Skived heat sink
- Forged heat sink
- Single fan assembly heat sink
- Swaged heat sink
These are the different types of the heat sinks that are offered in the market and each of these things is available in the different designs. In fact, they are different from the material, structure and more.
When you are buying the new electrical appliance or assembling the electronic device, you must consider some essential things. As the way, you know what is a heatsink and what its features are. So, it is important to have it on your device to give the reliability.
Even though, a variety of the heat sinks are available in the market and therefore, you can choose the best one among them. For this purpose, you have to take some important considerations in your account and they are provided as follows.
- The maximum allowable case temperature
- The limit of power dissipation of the device
- The highest allowable inlet temperature to the heat sink
All of these things are highly essential and needs to be estimated before you choose the right heat sink for your device. Of course, it is better to consider these things before buying the electrical component.
In this way, you can see what is a heatsink and how it is used in the electronic device easily.
