14 FAKE IT TO MAKE IT THERMAL SIMULATION Continuously growing requirements and more and more complex applications make some sophisticated preparation indispensable in particular in regards to performance and costs optimization in a market changing more and more rapidly. By involving thermal simulation in system development early on, thermal problems can be detected and remedied at an early stage. It offers the most efficient way to visualize temperature development and flow conditions. In a worst case scenario neglecting thermal management can lead to the complete failure of a project. In order to help their customers reach their goals faster, EKL AG has enlarged its development department substantially and further optimized their processes. EKL AG works with the simulation software FloEFD manufactured by Mentor Graphics. FloEFD is based on CFD methods. In combination with the latest hardware EKL AG now owns increased processing power to keep simulation times short. From now on EKL AG offers three attractive development packages (Basic, Plus und Premium) which, apart from designing the cooling solution, also comprise thermal simulation. According to the complexity of the project one of the packages is chosen while costs stay transparent. To ease choosing the suitable package the specialists with EKL AG are offering a system check in advance, free of charge. According to how things go, extensions or reductions to other packages are possible during the simulation phase. For 20 years now customers of EKL AG have benefited from the experience in developing customized cooling solutions and so can cut their time to market to a minimum. Development, prototyping, pre-series and mass production Everything from one source

15 CUSTOM-FIT HEATSINKS FOR YOUR APPLICATION Many different manufacturing technologies Customized heatsinks already for 500 pieces

16 MANUFACTURING TECHNOLOGIES Extrusion One of the most common production technologies in the field of electronic cooling is aluminum extrusion. Experience made over decades has turned EKL AG into a specialist as to design, optimization and feasibility assessment of your extrusion cooler. Favorable production in Asia and the so generated low tool costs enable us to supply even small and medium series of a tailor-made cooler. Low tooling costs Can be combined with other manufacturing technologies Standard procedure for producing Good thermal conductivity Various surface finishes possible Cold-Forging Fanless cooling of more and more efficient systems requires powerful cooling sinks having a extremely large surface. To cool these systems efficiently, EKL AG offers coolers coming from a cold forging procedure. Using high purity aluminum and copper in the shape of pin coolers meets these requirements in an optimum way. In contrast to extruded coolers more complex geometries can be manufactured as well. Apart from customized designs EKL AG also offers a selection of standard dimensions. Copper-, Aluminumheatsink made from "one piece" Standard sizes available High-purity aluminum with extremely high thermal conductivity Huge surface by round pins High material density Soldering The combination of aluminum and copper allows to cool high power density even in small components. The thermal "spreading effect" of copperplates in soldered joints with lightweight aluminum fins results in extremely low thermal resistance. By using punched aluminum fins an additional large thermal surface can be developed to cool systems fanless as well. Standard procedure for producing Copper - Aluminum combination possible High fin density / surface

17 Heatpipe Today the use of heatpipes in modern cooling engineering is indispensable. This technology of more than 30 years found its way into mass production more than 10 years before via the application in CPU coolers. The thermally highly conductive copper pipes work by means of phase change of the medium contained and so can convey hotspot to a suitable heatsink in your system effectively and rapidly. From the individual assembly as mounting kit up to finish soldered heatpipe coolers EKL AG offers a wide range of solutions. The use of qualified, high-end heatpipes gains a long-term stability which will always meet the high demands of our customers todays quality. Very high thermal conduction Highly efficient in small form factor systems Can be combine with other manufacturing technologies Heat transfer over longer distances possible Great design freedom and flexibility through increasing the number of heatpipes Crimped fin As a solderless alternative to soldered fin coolers EKL AG offers coolers equipped with mechanically pressed fins. The combination of aluminum and copper allows to cool high power density even in small components. The "thermal "spreading effect" of copperplates in soldered joints with lightweight aluminium fins results in extremely low thermal resistance. By using punched aluminum fins an additional large thermal surface can be developed to cool systems fanless as well. Solder-free connection (mechanical process) Powder coating possible Copper-Aluminum combination possible High fin density / surface No fin connection needed Die casting Closed systems where housing parts work as cooling device often require solutions made of die cast aluminum. Complex geometries as well as cast-on assembling fixtures can be implemented easily. Be it as motor housing or back of a panel application, the use of die-cast aluminum coolers is most versatile. EKL AG does not only provied production of existing designs but also support in respect to implementation and your ideas. More complex geometries possible Low prices mass production

18 Skived Fin Small form factor systems of low heights require optimum cooling in the smallest space. The skived fin procedure allows EKL AG to offer coolers made of aluminum or copper with heights of less than 30 mm which gainan extremely large surface without any additional thermal resistance caused by soldering or crimping. The skived fins are smoothly combined with the bottom plate. Because of favorable tools small series can be done as well. Copper-, Aluminumheatsink made from "one piece" Low tooling costs Higher fin density possible Surface finishing Whatever is needed - design driven requirements to surfaces, corrosion prtection or EMC guidelines, EKL AG provides your products equipped with the RoHS-conform surfaces required to meet the standard.
