What is the Working Principle of Aluminum Circular Coolers?
As with all coolers, there is an important law that enables operation in circular aluminum coolers. According to the physics law known as the second law of thermodynamics, the heat flow from the warmer to the warmer one occurs between two systems with temperature difference. This forms the main basis of cooling systems. The heat on a surface is transferred to a colder environment, ensuring that the system remains at the desired temperature value. In fact, this law forms the basis of working not only in coolers but also in heaters. As in the example of the heater, the heat of the hot water inside spreads to the less warm environment. While this situation warms the environment, it causes the water to cool. This shows that its coolers work in the same way as heaters.
How Do Circular Coolers Conduct Heat?
Aluminum circular coolers are designed to conduct heat conduction from the core to the outside. The reason why it is preferred especially in systems requiring rapid cooling, it enables the heat energy to spread to the air very quickly. Circular cooler designs consist of leaves surrounding the main mass in the core. The leaves form much more surface area by branching again according to the design. More surface area provides more air contact and heat conduction. The heat energy transmitted to the mass in the center spreads rapidly in the aluminum block and reaches every corner. In order for the block to come to thermal equilibrium within itself, the heat accumulated in the center rapidly transitions towards the ends of the block. The heat energy accumulated in the leaves at the ends of the blocks is carried by air and allows the heat in the system to be removed. In this way, cooling takes place.
How to Increase the Efficiency of Circular Coolers?
We can show the CPU coolers of desktop computers, where circular heatsinks are most used. Systems such as computer processors need to be cooled quickly. For this reason, circular coolers with higher performance are used. There are several different methods used to increase the effectiveness of circular coolers. The use of thermal pastes, which will increase the contact and heat conduction between the material to be used in the circular cooler and the cooler, is one of them. Other methods include expanding the surface area by adding more leaf branches to the block design, increasing the thickness of the block, and using heat conduction to the block body as a composite with copper systems. To increase the cooling speed, accelerating the air flow that makes the stone provides a solution. For this reason, fans are frequently placed on processor coolers.
