Cooling Sources in Electronics

What are Heat Sinks? In electronic devices, heat sinks are heat exchangers that are placed in different electronics and computers. To keep the whole device cool is the only function of a heat sink. There is a wide range of heat sinks, including forced or natural air cooling heat sinks and water coolers.

Active and passive are the two varieties of heat sinks. Heatsinks are made keeping in mind the heat a device produces. This heat needs to be absorbed to keep the device and its systems cool and functional. An aluminum extruded heat sink is the most common and most cost-effective means of providing the necessary cooling mechanism in an electronic device. 

Heatsinks are also provided with custom designs and features as effective cooling sources for different electronics. Some of the heat sink types are: 

• Skived fin heat sinks

• Folded fin heat sinks

• Bonded fin heat sinks

• Die cast heat sinks

• Stamped fin heat sinks

The CPU Cooler and its Function

In a CPU, the cooling system is of immense significance. CPU coolers are designed to dissipate the heat produced by different components working constantly in the unit. This type of air flow helps to moderate the temperature in any electronic device that produces excessive heat.

Failure of your CPU cooler can result in a problem like permanent damage of the device. Therefore, it is extremely important to have a close look at the cooling sources of any device to monitor whether or not they are working properly.

Fans of various sizes are placed in large computers to remove heat. This placement of exhaust fans in computers varies from model to model. Parallel and series installations of fans as cooling means in CPUs are the most common setups. Moreover, heatsinks are the most commonly used cooling sources that contain fins to offer the maximum cooling surface area to make contact with the air. 

There are many kinds CPU cooling sources, which include: 

• Active cooling sources

• Passive cooling sources

• Water and heat pipe cooling sources

• Exotic cooling sources

Liquid Cooling vs Heat Sink

Liquid cooling systems involve coolant-filled tubes, radiators and water blocks to keep the computer cool during excessive work. This setup sometimes includes a fan to help move around the water. However, in most computers, a heat sink is used to draw heat from the processing units. 

In some cases, heat sinks have proven inefficient in cooling computers. A device that produces excessive heat usually contains a liquid cooling system. This is mainly because water is an extremely efficient thermal conductor. Moreover, water can absorb more heat than heat sinks. In more expensive and advanced CPUs, the quality of the cooling source cannot be compromised. Therefore, the devices contain the most efficient cooling systems to make sure that heat produced in the processing units is being removed properly and efficiently. 

The effectiveness of liquid cooling technology, therefore, is preferred in modern computers and electronics. Liquid cooling means offer advantages, such as: 

• Efficient cooling boost

• Reliable for bigger, more advanced machines

• Preferable over traditional cooling sources
