Aluminum heat sink is a popular choice for any model home. They are very durable and easy to maintain. They can also be used indoors or outdoors. For residential use, they come in many different designs and materials. Some of the popular materials are cast aluminum, stainless steel, copper, brass, stainless bronze, pewter and satin nickel.

Copper is probably the most well-known heat sink material. Copper has high thermal conductivity and excellent resistance to corrosive and oxidizing agents. In particular, the copper extruded aluminum heat sinks category fits the cooling needs of many domestic projects.

Aluminum heat sinks come in stainless steel, copper, and satin nickel finishes. There are also extruded aluminum heat sink in other metals like aluminum and zinc, which are also widely used for their exceptional cooling properties. The metallic material is lightweight and has excellent thermal conductivity along with ductility. Aluminum alloy 10 1951A has one of the highest thermal conductivity values in the world at 225 W/m but is only mechanically mild.

In extruded heat sinks, the aluminum casing is made up of a thin sheet of metal that is bent into the open fin configuration. When the fin is pushed into the aluminum sheet, the two are joined by means of epoxy glue. Finishes could be brushed, electroplated with different colors, powder-coated, or left plain. The flat-top fin is usually coated so the aluminum can be painted white or black.

Installation typically uses PEX tubing with a stainless steel fin array. After the fin array is installed, the tube can then be soldered to the front or rear of the heat sink. Most heat sinks have holes drilled at their base for water supply and drain. Most pipes are fitted with a copper crimped end. A T-nut is pre-installed on the pipe for the connection to the PEX heat source. The T-nut is pre-drilled to accommodate the copper crimp as well.

Aluminium heat sinks have good dissipation properties because of their flat surface. The fins also have excellent heat conduction properties that keep the heat from the reservoir or heat source inside the unit circulating. Since aluminum has excellent thermal conductivity, it can also transfer the heat from the source outside to the inside of the unit. These unique aspects of aluminum make it a favored choice among many builders.

There are two types of aluminum. The first type of aluminum is purely aluminum chloride with or without additives. The second type of aluminum is made by adding copper. The copper is added to increase thermal conductivity, electrical conductivity, and anti-corrosion qualities. The combination of aluminum and copper improves the cooling effectiveness and efficiency.

You should always purchase a product that meets your needs and specifications. Make sure you are purchasing the right product for your residence. Keep in mind that aluminum and copper are two of the most popular active heat sinks classified. Other popular active heat sinks classified are granite, stone and stainless steel.
