Whether you need a heat sink for your computer, LED lighting, or any other application, a custom heatsink can be the perfect solution. These components help the heat from a source of heat move throughout the custom heatsink in a uniform manner. Heat pipes and other conducting devices help the heat move from hot spots to cooler areas. Regardless of your project's requirements, heatsinks from Heatell can help you meet your objectives.
The fabrication process used for custom heatsinks is highly varied. For example, machined heat sinks use highly precise tools and are generally made of aluminum alloys. Different manufacturers utilize different processes and materials for die-casting, ensuring high performance and durability. Die-cast heatsinks use copper or aluminum sheets that have been shaped into fins with varying geometries and thicknesses. The advantage of this type of fabrication is the high precision it offers.
ATS produces a full range of standard and custom clips for custom heat sink. These clips are used to attach heat-generating electronics to the heatsink. In addition, ATS can offer fast prototyping in the US manufacturing facility to help you make a prototype faster and more affordably. The best part of working with ATS is that they have hundreds of years of combined experience in manufacturing heatsinks for high-power electronics.
CNC machining is another method used to manufacture a extruded aluminum heatsink. This process involves cutting a solid block of metal using a computer-controlled machine. This method is very expensive and wastes most of the material cut from the main block. A CNC machine can easily cut through a block of metal and create a complex design with a lot of fins. Depending on the design, you can even have the fins placed with a slight curve in the base.
Aluminum is an excellent material for a custom heat sink. It is light, conductive, and non-corrosive. Aluminum alloy 6061 and 6063 have 166 W/mK - higher than copper's - and are the most popular alloys for heat sinks. Copper is also a good choice because it doesn't corrode easily, and it is not as difficult to process. Copper heat sinks are also easy to make and don't require extensive post-processing.
Another method of heat dissipation is through air flow over the fins. The amount of heat a custom heatsink can dissipate depends on the amount of heat produced and the difference between its ambient temperature and the heat sink's maximum operating temperature. It is important to remember that a custom heat sink may have different mounting methods and wattage requirements than other materials. Therefore, you must take into consideration your power source when designing your custom heatsink.
