10 Advantages of Pc Enclosures Compared to Industrial Computers
The demands on computers in industry are a lot higher than the demands of a conventional desktop PC.
Often environments in industry are the exact opposite of the optimum conditions an off-the-shelf computer is designed to run in. There can be large quantities of dust, dirt, grease and grime. It can be too hot or too cold and there could be many processes and cleaning that requires water, not forgetting the forklift trucks and pallet trucks that could completely destroy a PC if it got clouted.
The solution in industry and manufacturing has, for many years, been to use specialist solid state industrial computers. These machines are often intrinsically sealed, rugged and tough. They are often designed to be resistant to dust, dirt and grime and can also be completely waterproof.
These machines are also very expensive, not just to buy but also to maintain. Industrial computers have to be maintained by service engineer, often forcing shutdown of production lines they also have to be replaced periodically as the hardware and software will eventually become obsolete. All computers eventually fail but an industrial computer enclosure means that over three generations of computers can use the same enclosure.
Industrial PC enclosures are a more efficient, affordable and reliable alternative to these expensive machines. The main benefits of an industrial computer enclosure are:
1. Withstand the same environments as an industrial computer, whether that is dust (including explosive atmospheres), dirt, grime, oil, grease and water (even completely doused). Enclosures are rated using European IP ratings that give a clear indication to the types of environments the enclosure can operate in, for example IP 65 totally protects dust whilst protecting against strong jets of water, (the first digit, 6, represents the dust protection the second digit, 5, the water) while IP 66 offers the same dust protection but the enclosure can be completely immersed in water.
2. Enclosures can also withstand the same shocks, vibrations and tampering as the enclosure can be built from robust materials and the enclosed PC can be fitted snugly and secured with shock absorbing bolts. Enclosures can also be securely locked and bolted to floors or walls to protect against theft.
3. For computing in extreme temperatures, computer enclosures can in fact work to a better standard than industrial machines as the extra cooling and heating units can be replaced if they are not working as efficiently as they should (a sealed industrial computer that is running too hot or cold would need to be replaced or returned for an upgrade).
4. Computer enclosures can enable a PC to run equally as reliable as an industrial computer as the desktop PC housed in the enclosure can be any conventional machine, from a trusted office workhorse to the latest all singing, all dancing off-the shelf PC.
5. A computer housed in an enclosure is also far cheaper than an industrial computer. Apart from the initial outlay for the expensive bespoke industrial computer, enclosures can out live an industrial machine by over a decade as an industrial computer will eventually have an internal failure (as all computers do) or become completely obsolete and will need replacing. However, an enclosure can be reused to house another machine and will in general house three generations of machines.
6. A computer enclosure can house monitors, printers, touch-screens and all manner of computing equipment (including the peripherals such as mouse and keyboard ) or they can be combined with water/dust proof sealed keyboards and mouse.
7. As an enclosure houses a conventional PC, any repairs or upgrades can be carried out in-house in minutes rather than have to wait for an engineer and have to shutdown the production.
8. Enclosures can be manufactured from a range of material including food grade Stainless Steel.
9. Enclosures can be lockable and secured to walls or floors to prevent theft or tampering.
10. Enclosures allow you to choose which software or hardware to run inside the enclosure rather than suffer out-dated technology.
With the demands of industrial computing so variable and extreme, industrial PC enclosures offer a flexibility that even conventional industrial computers fail to match whilst also offering the same protection and reliability for a fraction of the cost. PC enclosures are ideal for even the most hostile industrial environment and while specialist PCs will always be required for certain tasks the majority of uses for an industrial computer can be achieved using a conventional PC housed in an industrial PC enclosure.

any tips on soldering aluminium?
planning to solder together pc watercooling waterblock out of aluminium i have lying around. i know aluminium soldering is tricky business and i have never done it before so im asking for some knowhow. im planning to use ALUSOL solder to do it,
Solder with water-soluble four-core flux. Suitable for soft soldering of aluminium, stainless steel and other low alloy metals. Not suitable for electrical joints and duralumin. Normally requires no prior processing of oxidised surfaces. Alloy: tin 18 %, lead 80.1 %, silver 1.9 %. Melting temperature between 178–270 °C. Suitable tip temperature 350 °C
a heat gun to heat up the pieces of aluminium and that's about it.
so far i know that aluminium high heat conductivity and oxidation make soldering it difficult, if anyone with experience on the matter knows some reason why my plan will not work or has any additional tips, please answer
Yeah, using aluminum solder takes a bit of practice.
(If you have any bits of aluminum scrap metal laying around, you might want to practice on some scrap before tackling the real thing.)
A heat gun probably isn't up to the task here. I suggest you get yourself a propane torch.
1)To start, make sure your joints are clean and grease-free. the best way to prepare the joint is probably either a bit of clean sandpaper, or a stainless steel brush, the point being to abrade off the dull oxide layer on the base metal. When it comes to making good sound joints, cleanliness is godliness.
Note: solder won't fill gaps or irregular joints; It's too fluid. If your joints have gaps or holes, you might as well take it to a welding shop and have them TIG weld it.
2)Apply the flux only to the areas you want the solder to flow onto, (unless you're using flux core wire...I recommend using a system with a separate flux)
(Protip: if possible, you can try wraping a bit of solder wire around the joint, like a twist-tie, then paint with flux.)
3)The trick with any kind of soldering is to heat the *base metal*, not the solder. (What makes this difficult is aluminum is a good heat conductor, while the melting point of the solder is relatively low.) With aluminum solder, you want to heat the base metal JUST to the melting point of the solder, without overheating! If you overheat, the flux will start burn up and you'll get porousity and oxidation in the joint.
Be patient and heat the joint slowly and very gently! Take your time! Generally, you don't need to heat the joint directly, but you can alternate heating on either side of the joint. Once the solder starts to flow, you can probably remove your flame at that point.
