Is heat sink a cooling system?
The heat sink belongs to the cooling system.
The heat sink is a kind of passive heat dissipation system, which mainly dissipates heat through the heat dissipation surface area and fins, but its heat dissipation efficiency is relatively low.
However, when used together with other heat dissipation systems such as fans or water cooled plate, the heat dissipation effect will be greatly improved.
Details such as the size and thermal solution design will affect the heat dissipation effect. How to design the professional thermal solution design, you can consult Awind for more assistance.
What is the difference between a heat sink and a cooling fan?
The majority of heat sinks are passive heat sinks, which transfer heat from the heat source to the air through the arrangement of the fins. Therefore, the heat sink is passive and has low noise.
The fan is rotated by the force exerted by the wire coil in the magnetic field. Electrical energy is converted into mechanical energy, and due to coil resistance, it is inevitable that a portion of electrical energy will be converted into thermal energy. Therefore, fans actively dissipate heat, will generate noise and heat.
What is the definition of heat sink?
The heat sink is made of a material with high thermal conductivity (usually aluminum or copper) through different processes. The heat sink is mainly used on equipment to dissipate heat. It is used to cool circuit components by dissipating excess heat to prevent overheating from causing failures, and to improve the reliability and performance of components.
When two objects at different temperatures come into contact, heat conduction occurs. Heat is transferred from the hotter area to the cooler area around it. Through this principle, the heat sink transmits the heat from the heat source to the surrounding areas, achieving a rapid heat dissipation effect.
