The heat sink has fins in its design that provide the necessary surface area to dissipate the heat. The fins act to cool the source of the heat and the heat sink itself. Consequently, the efficiency of the fins is an important aspect of the heat sink’s performance.
A heat sink is a traditional cooling solution that maximizes the surface area (using fins or pins) and airflow (using fans) to dissipate heat from the processor out into the surrounding air.
Electronic devices can generate a lot of heat. So, heatsinks play an important role in helping to cool them. You may be aware that aluminum is the most popular metal for heatsinks, but that copper is also sometimes used. You may also realize that copper has better heat conductivity.
Traditionally most heat sink manufacturers use one of two materials: copper or aluminum.
Most modern power electronics devices require controlled temperature environments, in order for them to function correctly. If the device overheats, the performance can be impacted, or in worst cases it fails and can become a safety hazard. The heat sink provides the pathway for heat to be efficiently transferred away from the device to the surroundings.
Heat sink compound is used to fill the gap between the CPU (central processing unit) or other heat generating components and the mechanical heat sink. The mechanical heat sink, a passive component made of a conductive metal, is placed over the CPU. Heat is drawn through the mechanical heat sink to its fins, where a fan blows air through to dissipate the excess heat.
Each heat sink manufacturing process has its own advantages and drawbacks. There are a number of different ways to make heat sinks. Let’s take a look at 6 common heat sink types.
The heat flow between the semiconductor die and ambient air is modelled as a series of resistances to heat flow; there is a resistance from the die to the device case, from the case to the heat sink, and from the heat sink to the ambient.
A heat sink is a passive heat exchanger. This means it transfers heat from an object to a coolant, either air or liquid. This coolant then dispels any heat generated by the object.
Whether you’re designing computers, LED lighting, or other electronics, you need to think about heat sinks. Heat sinks absorb and dissipate the heat from these devices, helping to keep them cool.
Heat can be transferred in three different ways: convection, radiation and conduction. Conduction is the way heat is transferred in a solid, and therefore is the way it is transferred in a heat sink.
To satisfy different functional requirements from our customers,we are making a big range of heat sinks products for our clients on base of different heat sink solution. Our heat sink solution from various manufacturing process including: CNC machining,extrusion,bonded fin,folded fin,cold forged,skiving,stamping,friction stir welding.
Aluminum is the second most common metal on Earth, which is fortunate since it is one of the most useful materials for a range of industries and sectors. The reason for aluminum’s popularity is its characteristics.
A heat sink is a metal designed aluminum heat sinksA heat sink is a metal designed to absorb and disperse heat away from a hot surface. Precisely, a heat sink is a thermal conductor and functions in the similar fashion. Aluminum and its alloys are used as the most common heat sink material but only next to copper. However, the price ranges of copper products is a setback and this is replaced by the aluminum heat sinks.
Heat sink material - The material used for constructing a heat sink has a major impact on determining its thermal performance. It is commonly known that most aluminum heat sinks are crafted from industry-standard aluminum alloys.
