Aluminium Extrusions in Racking Applications

Aluminium extrusion racking and racks are all around us. There are the obvious applications such as car roof racks and shop display racks but this material makes it an ideal choice for rack designers in a range of industries such as aerospace, sports equipment, electronic equipment and construction equipment.

Racks made from aluminium extrusions – it’s an obvious choice, due not just to the ease of manufacture but also to the native qualities of aluminium. It is also 100% recyclable.

The racks and racking must exhibit the following qualities:aluminium-racking

  • high strength
  • safe
  • durable
  • light weight
  • easy of manufacture
  • high corrosion resistance
  • low cost of maintenance

In an industry associated with constant innovation and revamping, the versatility of aluminium extrusions not only improves the efficiency in manufacturing and installing various components, but also offers a solution that is both aesthetically pleasing and functional.

Delivery and packaging of racks

Aluminium extrusions provide a practical solution for racks as they can be shipped in a small package and assembled on site. The small packages allow for greater carrying capacity on the delivery vehicles due to their weight and size with fuel savings gained during transportation. In use on a range of vehicles further fuel savings are gained due the light weight of aluminium.

Design and Manufacture

Using extruded aluminium to manufacture racks allows for elegant, low maintenance designs with green credentials and increased design innovation possibilities.

The extrusion process allows for an array of cross sections and curves that can be incorporated into the rack design and production process.

Surface Treatment

Aluminium extrusion racking finishing can include anodising, painting or powder coating to provide colour variations and extra weather protection.

Why use extruded aluminium instead of other materials?

  • Aluminium is lighter making it easier to assemble and maintain the racking
  • Aluminium and its associated fixings are safer by design
  • Extruded aluminium has a low cost of manufacture compared to other materials
  • It can be anodised or powder coated maintaining its appearance and won’t rust or rot

Keeping Electronics Temperatures Down and Performance Up

boardmount billboard-bga

Today’s Electronics Design Engineers are faced with the challenges of miniaturisation and also increasing performance demands. The issue with both of these is, as it always was, heat dissipation.

All electronic devices would be able to run faster if it wasn’t for the heat they need to dissipate. If there was no heat dissipation then devices would become unreliable, overheat and fail. So to produce reliable devices that have acceptable performance and long life, some means of heat dissipation is introduced. Smart phones and tablets get around this by using very little power and so heat isn’t so much of an issue.

One way of removing heat is to attach a heat sink.

Heatsinks are devices that enable heat dissipation from a hot component, usually the surface of a heat generating component, to a cooler, ambient medium, which is usually air.

In most situations, heat transfer through the interface between the hot component and the coolant air is the least efficient within a system. A heat sink placed on the hot component will improve the heat transfer by increasing the surface area, usually with fins, that is in direct contact with the air. This allows more heat to be dissipated and so lowers the component operating temperature. The primary purpose of a heat sink is to maintain the device temperature below the maximum allowable temperature specified by the device manufacturers.

Choosing a Heat sink

When choosing an appropriate heat sink to meet the required thermal performance, it is necessary to perform calculations and consider various parameters that affect not only the heat sink performance itself, but also the overall performance of the system. For example the air flow over the heat sink can be natural convection or forced by means of a fan and the method of attaching the heat sink to the hot component, usually thermal paste or tape, can affect the thermal performance.

Heat sink Types

There are heatsinks available for a variety of applications and include Extruded, Board / Surface mount, Fabricated Fin, and BGA that are all available in a variety of sizes, performance levels and fixing methods.

Extruded heatsinks allow the formation of two-dimensional profiles capable of dissipating large heat loads. They may be cut, machined and have options added. A cross-cutting will produce omni-directional, rectangular pin fin heat sinks, and incorporating serrated fins also improves the performance.

Board Level heat sinks are so named because they are generally attached both to the device and the PCB. Usually constructed as either a stamping or an extrusion, these heat sinks are designed for common package sizes.

BGA heat sinks are so named because they are mounted to BGA devices, but are actually just simple extrusions. BGA heat sinks are usually crosscut to convert the extruded fins into pins which allow them to be used in more diverse applications.

ABL has been a supplier of heat sinks to the electronics industry since its formation in 1975 and now offers one of the UK’s most comprehensive ranges of heat sinks. ABL is at the forefront in the design and manufacture of heat sinks and now supplies, from stock, many of the electronics industry’s most widely specified components from its modern facilities.

High Performance Heatsink Range will Assist Cooling

Improve your thermal performance now at a low cost as ABL Aluminium Components has launched a new range of high performance heatsinks.

As heatsink efficiency is largely determined by surface area, designers will aim to design heatsinks with as many fins as possible and as close together as possible.

High performance heatsinks offer a massive advantage compared to single piece aluminium extrusion heatsinks, such as excellent cooling performance and a favorable weight / performance ratio.

Our new range has differing options and can be provided in either solid or hollow fins. The hollow fin heatsink product is specifically designed for use with forced air cooling.

ABL Aluminium Components can also machine your components to suit varying needs on our CNC machines.

Check out the high powered heatsink range on our website www.abl-heatsinks.co.uk.

Dissipation of Electronic Component Waste Heat Via Heatsinks

When it comes to keeping electronic components cool heatsinks are a mheatrsink in goldust. Electronic designers have to increasingly rely on heatsinks as, CPUs for example, continue to increase in power and therefore have more heat to dissipate. Further compounding the heat dissipation issue is the need for miniaturisation. The task of the heatsink in removing heat at a rate suitable to keep the electronic component from overheating is becoming more and more difficult. There was a time when simple finned heatsinks would be adequate but as CPUs have grown in size and power and thus emitted more heat the simple finned heatsink can no longer cope despite increasing the finned surface area.

Temperature Difference

Electronic components have to work within a permissible temperature range and so at the higher end, where ambient temperatures can be uncomfortably high, removing heat becomes more of a challenge. Heatsinks rely on temperature difference and so the higher the ambient air temperature the less difference there is to produce a significant heat flow away from the heatsink and therefore the electronic component. Adding to local temperature within the unit enclosure are other components also trying to dissipate their own excess heat and so it is also necessary to forcibly extract heat from the enclosure and provide cooler air.

Reliability and Life Expectancy

Additionally the performance, reliability and life expectancy of electronic components are inversely related to the component temperature. For example an increase in the component   temperature corresponds to an exponential decrease in its reliability, performance and life expectancy. It is, therefore, important to effectively control the component operating temperature within the limits set by the design engineers to ensure long life and reliable performance.

Forced Coolingheatsink with fan

Attaching a fan to the heatsink will significantly improve its performance and thus the component it is cooling. Electronic designers are obviously aware of this and so a fan is incorporated to allow the component to operate at higher performance and temperature without loss of reliability or life expectancy.

ES Live 2014 Industry Football match

ABL Aluminium Components Ltd had Steve Judd, Sales and Production Coordinator, selected for the ES LIVE 2014 Industry Football match at Stadium MK, home of Milton Keynes Dons Football Club.

After a day talking to exhibitors about aluminium extrusion, heatsinks and the anodising process, Steve turned up at the changing room for the team he was selected for to meet his team mates for the evening.

The Tournament was a round robin with each team playing two matches on the MK Dons pitch.

Steve, started and played both matches at Centre Half in the May heat, even scoring a penalty.

Steve said ” It was an amazing experience to play football in a 30,000 seat stadium and on a lovely pitch, the biggest changing rooms I had ever experienced in football”

Steve was asked if it compared to his first love, playing tennis at Wimbledon, which he did years ago, the reply was quick ” No Chance” ” but was still Fantastic”.
