2 Local presence global competence invites you to take a look at our world of cooling solutions by utilizing and combining our expertise with the unique properties of intelligent aluminium extrusion and, if you like what you see, to take the next step by entering into a partnership with. has 4,000 employees in 5 countries and sales of USD 5 billion/eur.8 billion As the world s largest provider of extruded aluminium profiles, is a leading supplier to all sectors using aluminium as the strategic material: transportation, general engineering, solar, telecom, renewable energy, and more... Aluminium Profiles: we make them simple or advanced, big or small, direct or indirect and with high aspect ratios. We deliver profiles from over 00 extrusion presses, from as small as 5 mm (0.0") and 0 g/m (0.00 lb/ft) to profiles up to 60 mm (4.0") and 65 kg/m (4.7 lb/ft). Add to that our technical expertise: R&D Technology Centre, design support Testing and FEM of structural profiles and components As part of our global centres of excellence, we have specialists in the area of thermal management with in-depth knowledge of manufacturing, product design, prototyping, testing and analysis, and project management. We aim to become your preferred supplier of extruded aluminium cooling solutions. You are also welcome to visit our website or contact our team: thermal.management@sapagroup.com Intelligent aluminium profile solutions Endless opportunities It is possible to integrate a wide range of functions into an extruded aluminium profile. s idea profile (picture on the right) illustrates some examples: e.g. heat sinks, integral tubes, hinges, latches, screw ports, decorative patterns, slots for screws, rivets or rubber seals, lugs, etc. Built-in profile features reduce your manufacturing costs and enhance functionality. Do not hesitate to exploit our wealth of experience from millions of profile designs.

3 Extruded aluminium profiles the perfect starting point for developing customized cooling solutions Get started with your own profile design Our competencies and production capabilities make us a major supplier across broad sectors like renewable energy, transportation and general engineering, and in specialized industries like LED lighting, power conversion, telecom and medical equipment. Features like thermal conductivity, strength, ductility, corrosion resistance combined with low weight and the cost-saving potential of integrating intelligent features into the profile are unique and comprise important tools in our Thermal Management toolbox. At the same time, we can help you to choose the right alloy that meets the requirements in the manufacturing of your final cooling solution.

This identifies the potential improvement from using advanced thermal analysis and complex product simulations using FEA (linear static), fluid dynamics, assembly/ tolerance analysis or snap-fit design. With these services we can identify further options for: reducing material content, delivering optimized sections, proposing simplified assembly and bringing you even more fabrication options. 40% better cooling performance and 0% weight reduction. Innovative and cost-effective solutions are all about knowing how to optimize component design. At we combine our extrusion experience with Computational Fluid Dynamics (CFD) and other advanced simulation techniques.

4 We add value to your heat sink solutions and help you to enhance your performance Special Cooling solutions There may be regional variances in our capabilities, contact your regional office with your specific enquiry. We are experts in aluminium design and extrusion technology. Add to that our Embedded heat pipes world-wide technology centres comprising specialists within engineering, marketing, machining and product design. They are the ones who understand your industry and can make your innovations become a reality. In the heat-sink industry we know from experience that improved thermal performance using aluminium extrusions often leads to longer service life higher efficiency lower overall system costs Using embedded heat pipes spreads the heat more uniformly over the heat-sink base. A heat pipe is a passive device with highly effective thermal conductivity. The heat pipe can be bent or flattened before soldering/bonding, which extracts heat from a device very rapidly and bonds it to the bent aluminium heat-sink base. Embedding heat pipes into heat sinks by soldering improves thermal performance compared to the original extruded heat sink shown below. has the resources not only to design, but also to simulate and test a new liquid cooler concept. to liquid coolers with Friction Stir Welding technology The unique possibilities of Friction Stir Welding enable us to produce liquid coolers with outstanding performance. Liquid coolers can be Take advantage of highly conductive copper, without increasing the weight or the cost! Copper pads designed with lower weight, lower total costs and, in many cases, improved heat-transfer performance. The joints can be made to be very flexible, because no filler metal is used in the FSW process, while high conductivity and strength are maintained at the joint line. One of our liquid cooling designs has been success- Aluminium heat-sink performance can be improved by integrating copper pads into the base, by either soldering or Friction Stir Welding. Copper s excellent heat-transfer properties are used to reduce the temperature in high-load areas. fully lab-tested in over 5,000,000 leak-proof cycles. has the resources to not only design, but also to simulate and test new liquid cooler concepts.

5 Don t just dream of sophisticated fabrication ask for it..! operates a global network of manufacturing facilities. We offer our customers a broad range of fabrication, from advanced CNC machining to traditional tooling like cutting, punching, milling, drilling, etc. is a global leader in Friction Stir Welding but we have also access to traditional welding and other joining technologies. Surface treatment design and function capsule and component In many business areas, the surface of our extruded aluminium solutions is an integral part of the design. But we also offer various surface treatments if additional coatings and protection are required. Customized seminars produce customized solutions! A partnership with is your passport to our world of R&D expertise in aluminium and our global network of production sites. Let conduct your next technical in-house seminar and tailor a team of specialists who know your industry.

6 Standard heat sink solutions At some of our locations, we offer our customers a range of standard extruded heat sinks for various applications inverters telecom LED drives medical equipment. Contact your local sales representative to hear more. Bright light for a green sector LED lighting might not be a novelty anymore. But the breadth of its fields of application certainly is. The luminaries of Fionia Lightning a research company related to the University of Southern Denmark are a shining example. After five years of R&D, Fionia launched its LED-lighting fixtures that will save up to 40% of the energy required by conventional lighting systems. High fin density heat sinks Aspect ratios up to 0: or more are possible using s pressed fin solution in combination with Friction Stir Welding. Low contact resistance in the base due to joint configuration enables a high flow of heat. Customized fin spacing, thickness, and lengths to meet pressure-drop requirements and optimized surface areas are also possible.
