Heat Sinks

Heat Sinks in Aluminum draw heat from another source from thermal contact. These are mainly used in electronic parts and automobile parts but there are other uses like:

Airplane parts
• Circuit boards
• Microwaves
• Cell phones
• Satellite components
• Laser components
• Motor housings
• Automotive
• Lighting parts

Aluminum Heat Sinks absorb and dissipate the heat from another object. It is a piece of molded aluminum or copper that usually sits directly on top of a feverish source or processor. In many cases, you won’t be able to see the processor unless you take out the aluminum heat sink first.

Wherever there is a need for efficient dissipation of heat, there will surely be aluminum heat sinks installed. A major industry that uses heat sinks is refrigeration.

The aluminum heat sinks manufactured these days come in different shapes and sizes. The typical heat sink though, has long fins and thin protrusions for conducting the heat from the processor to the cooler environment inside the aluminum heat sink. Die Casting Companies make heat sinks.

Most of the heat sinks in the market these days are equipped with fans that blow the cool air to the fins to dissipate heat more effectively. These fans or blowers are usually placed on top of the fins or in the middle.

Aluminum heat sinks are designed to require less machine processing. The fins can be manufactured simultaneously with the mounting holes. Typically, about 250 to 2500 heat sink parts can be produced per day.

Aluminum Die Cast Heat Sinks

Aluminum Heat Sinks are objects that draw heat from another object through thermal contact. They are mostly used in electronics and automobiles. Aluminum is a lightweight and sturdy material that has good thermal and electrical properties, that’s why it has become the material of choice for most heat sinks.

Aluminum heat sinks are produced by die casting by a Die Casting Company, a process wherein molten metal is forced is forced into mold cavities. The die casting process is beneficial if you are producing large quantities of small to medium sized automotive parts with good details. Prior to the introduction of die casting, most heat sinks are made by welding several pieces together and drilling holes, if required, after. This process is time consuming, costly, and labor extensive. Die cast aluminum heat sinks are good as raw parts but they can be powder coated and anodized easily.

Die Cast Aluminum heat sinks can be manufactured in a much faster rate—ranging from a few hundreds to a few thousands small to medium sized parts a day—because they can be produced in net shape and there are no welding and drilling methods needed after. Die casting saves time, money, and energy all together.

Die cast aluminum heat sinks are definitely lighter than their stainless steel counterparts, with a specific gravity of about 0.10 pounds per cubic inch. Because they are electrically conductive, aluminum heat sinks are used for radio frequency (RF) and electronic magnetic inductance (EMI) shields. This quality also allows them to be grounded easily.

Aluminum heat sinks are used in airplane parts, circuit boards, microwaves, cellular phones, satellite components, laser components, motor housings, automotive, lighting parts and many more.

Extruded Aluminum Heatsinks

Extruded aluminum heatsinks are made by heating aluminum to the point of a semi-solid state. Then this aluminum is pushed (extruded) through an extrusion die. These aluminum forms have the profile of the die it was pushed through, much like the play dough toy extruder. The simple shapes are stars or circles. These forms are cut to the length needed.

Aluminum Heatsinks that are extruded typically have a flat bottom and ribs on the top. They can be extruded in lengths of several feet an cut to shorter lengths. Because these extruded aluminum heatsinks were formed by pushing through a die, there is a limitation on details that can be formed on the top and bottom surfaces. If a depression is needed to mount components then it will need to be machined into the part as a pocket as an after operation, dramatically increasing the part cost. More typically, if holes are needed for mounting, they too will need to be machined into the parts as a secondary operation. Any other holes needed so wires or components can pass through have the same limitation.

The Aluminum Die Casting Process injects metal into a mold or die that forms the top, bottom and sides. Mounting holes, through holes and cavity indentations formed into the part are in the die halfs on the top and bottom. Aluminum Die Casting Heatsinks will have all the features necessary for installing the components and the holes for mounting during the original manufacturing operation. Die casting heatsinks will not require secondary operations for holes and features.
