the metal boxes are much too expensive for me...and I just don't think them to be worthy. I made this at my home so I can only deal with paper-made boxes..sorry. and where to find 16mm2 wires? the largest wire I could find is about 10mm2 and extremely expensive...[s:275]
the heatsink is large enough at this moment.. and if the heat-dissipation situation become worse, I'll just simply open the box and put a large fan on it....isn't easier and cheaper??
and i think that rather than using 16mm2 solid copper wires, using copper tubes of diameter 8mm or 1cm would be a better choice.. the price is nearly the same and you know, high freq currents tend to go near the sur face[s:228]
