HEAT SINK SE46

Aluminium heat sink acts as a heat exchanger .It transfers the heat to a medium with lower temperature. Dimension HEAT SINK SE46 .

Basic information

Heatsinks is like the most fit player of the electronic and electrical components team. Heat that if left unchecked could reduce the life span or even destroy outright the processor that created it. Thermal management increasingly needed when dealing with electronic devices to satisfy the objectives and of functional integrity and operational integrity. A lower temperature will yield satisfactory function and increase the expected life of the electronics. The application of a heat sink satisfies those two objectives. A heat sink is a heat dissipation device that consists of a base and fins that extend outward. The performance is affected by air velocity, choice of the material, fin design and surface treatment. When a chip heats up from use the heat sink removes and disperses the heat to keep chip at a proper operational temperature. The heat comes in to the fins and then the flow takes it away by change of the enthalpy across the surface. Without the use of the heat sink the chip would over heat which could destroy the entire system. Anodizing is the electrochemical process that thickens and toughens the naturally occurring protective oxide layer on the surface of metal. A heat sink is a heat exchanger that transfers the heat generated by an electronic or a mechanical device to a low temperature fluid medium, often air or a liquid because, air and liquid have lot of space for atoms to move and create energy. There are premierly 2 types of heat sinks .

• Passive heat sinks
• Active heat sinks

Passive heat sinks are those that don’t rely on forced air flow (fans) and are considered more reliable than active solutions. So, we can say that passive heat sinks are more natural in terms of their mechanisms.
