Extruded Aluminum Heatsinks from Cooling Source Are the Ultimate in Heat Sink Extrusions

It would be great to have someone walk into your place of business and meet all of your extruded aluminum heatsink needs. Cooling Source is the next best option. We have an extensive inventory of heat sink extrusions.

Any order can be fulfilled quickly. We offer both standard and custom extruded aluminum heatsinks. On our website, you can browse through our catalog of heat sink extrusions we have in stock. We have an online form for customers to use to request a quote with or without an existing heat sink. A customer representative will respond quickly.

Custom Heat Sink Extrusions

Benefits of custom heat sink extrusions include:

• Keeping tooling costs low
• Achieving a low per piece cost
• Little or no secondary machining

Heat sink extrusions are made in a variety of shapes. Each is designed to fulfill a particular need. Our Cooling Source experts can explain the benefits of a process and help determine which of our extruded aluminum heatsinks best fits your needs.

The advantages of extruded aluminum heatsinks are:

• Improved cooling performance provided by high fin density
• Lighter in weight than copper
• Work more efficiently than stamped heatsinks
• Cost less than machined assemblies
• Wide variety of customized designs
• Useful flat backs for power module components
• Geared unique shapes for electronic power assembly use

Time associated with the machination of an equivalent block aluminum form is eliminated

Extruded Aluminum Heatsink Finishes

Cooling Source offers finishes that protect heat sink extrusion parts against hazardous environments. For extruded aluminum heatsinks, we use an anodizing finish and chromate finishing. Anodizing is an electrolytic passivation process that increases the surface's natural oxide layer.

The finish is made of aluminum oxide. It is a sturdy finish that has excellent emissivity. Hard anodizing is implemented for high-temperature applications. The finish is electrically non-conductive. It is a low-cost option that is available in custom colors upon request.

A chromate finish is a conversion coating option that passivates aluminum. Chromate finishes are corrosion inhibitors. They prevent the extruded aluminum heatsinks from tarnishing. A chromate finish is electrically conductive. It is also a low-cost option that is available in yellow or clear.

We have earned the trust of our customers by offering service, reliability, and quality products. The world class customer service, extensive inventory, and the latest technology and engineering solutions are what we use to maintain excellence.

Uses for Heatpipe-Assembly

Heatpipe-assembly offers solutions for thermal performance, help in the control of energy costs, and maximize the reliability and life of a system even under conditions that are harsh. When space is limited, a heatpipe-assembly is a compact thermal solution for cost-effective cooling.

A variety of heatpipe-assembly systems can be used to accomplish the task. The heat technology gives an effective means of moving heat for remote dissipation. Low thermal resistance heat spreads from isolated cooling or concentrated heat sources to protect applications such as:

• Military systems
• Transportation control systems
• Consumer electronic devices
• Computer components

When a system design makes it difficult to place a heating device adjacent to a critical component for essential cooling, remote dissipation thermal management is a solution.
Application Constraints that Benefit from Heatpipe-Assembly

• Space constrained by footprint or height – The height over an electronic module may be insufficient in the amount of space provide direct cooling at the location. Remote heatpipe assemblies can be effective solutions. When where is not enough room to increase the footprint or height of an existing heat sink, vapor or embedded chamber assembly may be the solution. When there is no restriction above the heat sink, vapor tower technology can be used. 

• Zero or limited electrical power construction – Natural convection cooling improves reliability and eliminates fan noise. A heat pipe will produce less noise than a large fan system when volume constraints limit natural convection cooling solutions. 
• Low maintenance – Electromechanical devices such as fans require maintenance and have a finite life. A heatpipe-assembly has no moving parts to fail. Maintenance requirements are reduced or eliminated. 
• Cooling in sealed enclosures – Electronics are sometimes sealed in an enclosure as protection from the environment. Heat needs to be dispelled to the outside of the housing. A heatpipe-assembly provides a thermal path to the wall of the enclosure. 

Any of the above constraints merit the use of a heatpipe-assembly.
