Of course, you should have patented this _before_
posting... |
|
| |
I suspect it probably has already been patented, like every other idea ever. |
|

You might want to discuss that with [2fries]. |

Since most systems are designed to collect the dust, but this one isn't (it merely keeps the fan clean during extraction), there doesn't seem to be anything like this out there (but I'll keep digging... not that Google knows everything).
This is a good idea, as long as the benefits of a cleaner fan and less maintenance offset the expense of complexity and greater power usage (admittedly, it won't be much power...). |
|
| |
While trawling Google for prior art, I came up with the perfect target market for this system: computer cooling fans.
Run the conveyor around the outside of the parts to be cooled, so both the fan and the motherboard/whatever are inside the belt; dust from the room doesn't get into the guts. It will reduce the cooling efficiency somewhat, and the case will need a more defined air inlet and outlet (more "duct", less "a bunch of air holes somewhere"). |

(+) Make sure the rollers aren't made of too dissimilar materials or any metal ducting might have some kind of Van de Graaff effect from the static. |
|
| |
Build it around the computer itself and it would look like
some weird Star Trek force field. [+] |
|
| |
/The trouble is, it'll blow the same dust back out there into the air,/
That is why I did not think the linked blower scheme would be good for cooling small items - these coolers just move ambient air around. |
|
| |
If there is any issue with the fact that this concept, as described, makes insufficient use of flames may I suggest that the screen duck under a baffle on return back under the fan. Under the baffle are flames (or possibly hot wires if one does not want to hook it up to the gas) which burn off any remaining tiny adherent particles not blown free. |
|
| |
Having personally pulled big wads of dust from around my computer's fans, while realizing how much thermal stress it must have been putting on the computer, I would like to see this idea applied to computer cooling. [+] |

<old joke> My mate used to collect old farm
equipment. He's an ex-tractor fan. <\oj> |

Thanks, [MaxwellBuchanan]; that's just the right amount of silly for a Thursday morning :-D |

If the filter belt is woven in a way such that fan air flowing by tends to push it along the same direction the belt is meant to travel, there may be no need for motor or mechanism to move the belt. |
|
| |
If dust traps are well placed downstream of the entire fan and filter, they could be come clogged and overflowing and still not drop the fans efficiency. |
|
| |
I did a search for the performance-size curve for fans but I couldn't find anything useful. The question at hand is whether the smallest possible fan can successfully dislodge the smallest likely Detritus. I think not, and that electrostatic removal is a much better option. |

Sorry [Max] I didn't notice you fawning over me again until you changed [21q] to [2fries]. |
|

There are many new things under the sun.
Yes Virginia... there is an easter bunny. |
|

//changed [21q] to [2fries]// Yes - names with digits
sometimes confuse me. Sorry about that. |
|

Any luck with the dowsing yet? |

That would be ideal, because it would never wear out - only one side is ever used. |
