To manufacture aluminum extruded pin fin heat sinks, firstly we should get the aluminum extrusion profiles by extruding the ingot through the tooling die. We generally need to put the aluminum billets in a high temperature environment of 350~500 °C, use a large extruder to apply high-intensity pressure, and extrude the aluminum billtes through tooling die to make the designed cross-sectional shapes. Definitly the tooling die needs to be designed. Aluminum extrusion production process is aluminum rod, heating, extrusion, cut to length, cross cut.
Aluminum extrusion heat sinks are widely used in various fields such as heat exchangers and radiators of refrigeration and heating equipment, air conditioners for vehicles and other daily necessities, from leisure products to aviation equipment and other fields, so the development of aluminum extrusion heat sink is very active.
Why use extruded heat sink?
(1) More efficient than stamped heat sinks;
(2) It is more cost-effective than machining;
(3) There are a variety of standard shapes and sizes to choose from;
(4)Customization is much easier than copper, as ithas obvious advantages of weight and cost;
(5) The MAX CLIP fastener system does not require installation hardware and tools.
Aluminum extruded pin fin heat sinks can offer more surface area to dissipate the heat which makes this type of heat sink own better thermal performance, besides, the pin fin structure can make the work steady when the ambient air flow is not stable. Extrusion heat sinks are generally for high-power electronic components and systems. Sinda Thermal can provide reliable natural convection environment solutions based on the existing mature aluminum extrusion heat sink technology. The aluminum extrusion profiles are extruded from the tooling die, which can make the complex fin structure. These complex cooling fins increase the heat dissipation surface area even more, while reducing the cost and time of machining.
