What is conduction in cooling system?

Conduction Cooling: This is defined as the transfer of heat from one hot part to another cooler part by direct contact. The advantage of this method of cooling is that no electromechanical fans are required. Another type of convection cooling requires forced-air-flow via fans or blowers across the power device.

What are the design considerations of heat sink?

Some of the key factors that should be considered in heat sink design include thermal resistance, material, fin configuration, fin size and shape, fin efficiency, heat sink attachment method, and thermal interface material.

How can I improve my heat sink design?

Natural and Forced Convection – Since a heat sink works by dispersing heat to the surrounding air, the process can be improved by moving that air parallel to the fins of the heat sink. This will lower the effective thermal resistance of the heat sink, while ensuring that the ambient air remains at a lower temperature.

Is conduction a cooling process?

In situations where you have adequate space, a sealed enclosure or require no audible noise, conduction is a reliable cooling option. Conduction doesn’t require pumps or fans to operate, and instead, relies on heat transfer between parts of a continuum, through direct physical contact.

How do conduction and convection differ?

While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves.

What is the best heatsink material?

Aluminum alloys are the most common heat sink material. This is because aluminum costs less than copper. However copper is used where higher levels of thermal conductivity are needed. Some heat sinks use a combination aluminum fins with a copper base.

What is the thermal resistance of a heat sink?

The contact between the device case and heat sink may have a thermal resistance between 0.5 and 1.7 °C/W, depending on the case size and use of grease or insulating mica washer.

What material makes the best heat sink?

Aluminum is the most common material for heat sinks. In particular, extruded aluminum heat sinks fit the needs of most projects. The metal is lightweight and has relatively good thermal conductivity.

What are cooling fins made of?

In most high performance applications, fins are made of copper or aluminum. Aluminum fins are preferred in aircraft electronic liquid cooling applications due to their lighter weight.

What is the role of fins in cooling system?

Cooling fins rely on conduction to diffuse the heat away from what is being cooled. The fins are designed to increase the surface area with another liquid (air for example). Here the heat is transfered using convection, cooling the fins and warming the liquid.

What are condconduction cooling solutions?

Conduction cooling solutions rely on direct contact with materials with high thermal conductivity to effectively transfer heat.

What are the benefits of conduction cooling solutions?

One of the key benefits of conduction cooling solutions is that they are passive solutions that don’t require moving components, meaning high reliability, less wear and tear, and low maintenance. Heat spreaders can be integrated into complex assemblies or geometries for high performance chassis or enclosures where internal volume is at a premium.

What is passive conduction cooling?

Talk With Us! Passive conduction cooling is an essential tool for reliable heat transfer and one of Boyd’s areas of expertise for over 50 years.

What is a thermal busses made of graphite?

Boyd is the pioneer in utilizing encapsulated graphite to create lightweight, yet highly thermally conductive solutions. Thermal busses integrated with k-Core® to combine the lightweight benefits of graphite with the strength of copper or aluminum and offer thermal conductivity greater than the encapsulating material.
