    IcePak - Pressure Drop and Fan Operating Point

    Good Day, I was wondering if there were any icepak user here that could help. Is it possible (and how do you do it) to give the pressure drop of a system (An electronics enclosure containing a heatsink, heat sources, grill inlet and exhaust fan for example), and also to give the operating...

    Stamping Copper

    Good Evening, I am looking to design and make a machining that can stamp out a 5mm hole in 3mm think copper. I was wondering how I would go about calculating the force needed to do this. Also, does anyone think that this would be possible pneumatically with an air piston running off an air...

    Drawing Template - Back ground image sent back

    Hi, Does anyone know if its possible to add an image to a drawing template that would appear behind any other objects (Drawing views, tables, etc). For example, if you want a large company branded image in the upper right corner as a drawing background, then as you place your vesision table in...

    Part Numbering after a surface finish

    Hello All, I was wondering how you all manage your part number if you potentially have a product sitting on a shelf unplated, and the same product plated. Do you have a serperate part number for the unplated one. Send it out for plating, then book it back in as a different part number?

    Force Requirements

    Evening All, I'm after some guidance on how I calculate the force required to bend a piece of aluminium. Basically, I want do design a device that will bend a 1mm thick piece of aluminium, about 500mm wide in to a U channel shape. I plan to use tool which is a U channel shape die, and a form...

    Heat Transfer with Solar Loading

    Good Day to All, I'm a bit puzzled by a phenomenon that I'm seeing during a set of CFD simulations. As an example, Say you have an enclosure with an internal heat source that is thermally connected to this enclosure. There is a solar load beating down on the enclosure. Simulation shows, when...

    Absolute Limits

    Apologies upfront is this is a basic question But I was wondering, say you have a number of thermal parameters for on a forced convection heatsink, such as Dimensional Limits, Ambient Temp, Required Temp rise, heat power, heatsink total surface area, and air flow rate. Is there a simple quick...

    Beam / structure Calculations

    Good Afternoon, Over the years since qualifying as a mechanical engineer, Ive wanted to learn more about structural mechanics. We learnt a fair bit about about beam analysis when I done my degree 15 years ago, and the fact I went down a thermal engineering route means Ive had to dig out all the...

    ISO9001

    Hi, We are looking to apply for our ISO 9001. I have come across BSI and QMS as auditors / consultants, but someone told me that certification by QMS is not regarded as very good. Is this true?

    Thermal Impedance - Puzzled

    Sorry to trouble peaple for such a basic question, but Im trying to get my head around thermal Impedance. Say you know Junction to Case Impedance of a IC chip, and say is was 5°C/w. The IC was producing 1w of power. Then you knew the Case Temperature (say 60°C). Would the Junction temperature...
