  • Bonded Fin

    Our bonded fin heat sinks are manufactured from either aluminum or copper metal sheets, or by using an extrusion process. Using either epoxy or a solder/braze process, they are then bonded to the base. Each process is designed to meet specific needs and our knowledgeable consulting is always available to answer any manufacturing questions you may have.

    Bonded fin heat sinks are generally designed for high power application with low thermal resistance. Forced air cooling is required for these products.

  • Cold Plate

    Cooling Source, Inc. utilizes a range of technologies and round or flat tubing to produce performance-fin cold plates with a liquid-cooled chassis.  Designed with the increasing demand for compact designs  in mind and with an accompanying requirement for power densities, this type of manufacturing satisfies the increasing demand for compact cooling requirements.

    Utilized by fields as diverse as high-powered electronics, lasers, power drives and medical equipment,  and often supplied to the military and aerospace industries, cold plate technology is the perfect choice for your high-power requirements. If you are faced with high watt densities and air-cooled heat sinks are inadequate, liquid-cooled cold plates offer an ideal high-performance heat transfer solution alternative.

  • Die Casting

    Die cast heat sinks are perfect if you need a custom designed aluminum heat sink. They are manufactured by forcing liquid aluminum under high pressure into re-usable steel molds. This is often an ideal solution when you require a more complex design in high volume and with lower thermal conductivity.

  • Extrusion

    Our standard aluminum heat sinks are the perfect solution when you have both low cost needs and fast to market requirements and are available in either standard or customized types.  An aluminum block is pushed or drawn through a die to create a straight or cross-cut finished product. Each is designed to meet a specific need, and our experts can help you decide which is best for your application.

    Extrusion heat sinks can be a great choice when you require a low tooling cost, a low cost per piece, and little or no secondary machining.

  • Folded Fin

    Folded fin heat sinks are manufactured by bending aluminum or copper sheets into a variety of fins which are later bonded to a base. This type of heat sink allows for the base and the fins to be manufactured from different materials and can be an excellent choice when you require a thin fin of light weight, differing materials for fin and base, and a low tooling cost.
