What is the Cooler (Heat Sink)?
Cooler (Heat Sink) systems are much needed equipment especially in the field of electronics. Development in electronic technology enables chips to work much faster and with high efficiency. However, as the chips work, the problem of heating occurs. Systems that are not properly cooled break down in a short time. There are passive cooling systems and active cooling systems among the systems that will effectively cool the systems to prevent malfunctions. The cooling system known as Heat Sink is designed using basic thermodynamic principles.
How Does The Cooler (Heat Sink) Work?
The working principle of Heat Sink (cooler) equipment is based on basic heat dissipation principles. Conduction (conduction), convection and radiation (radiation) are the most basic heat conduction principles. Cooling systems allow the excess heat in the material placed on it to flow onto itself. The heat accumulated on the cooling block, on the other hand, contacts with the air that is less warm than itself and ensures that the heat is removed from the system by convection. Cooler blocks are generally produced from aluminum and copper materials with strong heat conduction. In this way, it removes the heat in the hot system much faster. In order to increase the efficiency of the cooler (Heat Sink), various leaf designs are made to increase the level of transport of the material with more contact surfaces.
How To Determine The Cooler (Heat Sink) Performance?
Heat always tends to flow into the less intense environment. The thermal conductivity coefficients of the materials transmit heat faster or slower according to the [W / (m.K)] value. The high heat conduction coefficient of the material used in cooling enables faster cooling. Other factors affecting cooler performance are the weight of the material, the width of the surface area, and the effect of the coating on the heat conduction. Surface area is one of the most important factors. Widening the surface area allows it to come into contact with more fluids and to provide more effective cooling. For this reason, while designing the cooler (heat sink), production is made to expand the surface area and accelerate the flow. An external factor affecting the performance of the cooler is the flow rate of the fluid in contact. Fluid, which is generally air, is also used as water and oil in different systems. The performances of aluminum cooler (Heat Sink) models vary according to these factors.
