Aluminum Heat Sinks

We produce aluminum heat sinks and other extrusions according to stock designs or special designs prepared by the customer. All our products are made of highly resistant alloys 6060 and 6063. We are located in Russia but welcome international customers and ship to all countries around the world.

Types of Aluminum Heatsink Extrusions

Aluminum heatsink extrusion profiles are applied to improve the heat dissipation of highly heating elements or to redirect heat to the cooling medium. It is irreplaceable in electrical power and radio equipment. We offer for sale various kinds of heat sinks.

How Heat Sinks Work

Many heatsinks work with so-called cooling fins; a grooved plate that (possibly together with a fan) provides cooling. Air-cooled engines often have cooling fins on the cylinder and cylinder head. Due to a larger contact surface with the air, the block gets cooled faster. Cooling fins are made of good thermal conductors, usually aluminum. Optimal contact between cooling fins and components to be cooled is ensured by polishing the fins and by applying a layer of thermally conductive paste (e.g. colloidal silver).

The cooling effect of heat sink extrusions is measured in degrees Celsius or Kelvin per watt (°C/W or K/W), which means that every watt of power will make the device much warmer. The lower this value, the better a heat sink works. Vertically installed heat sinks work better than horizontal ones because the radiated heat rises whereas cool air gets drawn in.

Applications of Heat Sinks

Aluminum heat sinks are widely used in power electronics such as power supplies, computer processors, and amplifiers. Also, power resistors often feature them. Where static cooling is not sufficient, fans can be added so that the airflow along the cooling plate increases the heat dissipation to the environment. This is called forced cooling.

The temperature increase of electronic components, such as a microprocessor, can be limited by distributing the heat over a larger mass and allowing it to exchange (by increasing the surface area) with the ambient air.

Why Choose Our Heat Sink Extrusions

If you are looking for a cooler for your technical equipment, take a look at our offer. We offer durable, eco-friendly aluminum comb profiles in various sizes at low prices. Though they differ in shape, the number of fins, and wall thickness, their high quality remains unchanged. We use modern high-tech equipment and raw materials for our production. Our aluminum profiles meet the latest industry standards and customer requirements.
