Does anyone need some largish heat sinks.

Question

I checked the local scrap yard today and found some power semiconductor stu ff. Did not have suitable tools with me and am thinking of going back on M onday with a better assortment of tools. I noticed two or three heat sink s and thought if anyone uses such things ,I could buy them and ship them. The scrap yard charges $1 a lb. for aluminum. My guess is they weigh about 12 to 15 lbs. I did not measure them,but they are about 5 or 6 inches by 9 to 10 inches in cross section. Could not see the length, but would guess they are about a foot long.

Could not see the length, but would guess they are about a foot long. Bad guess.  I went to the scrap yard today.  The heat sinks are 5 inchs by 5 inches by 20 inches.  I  took two IGBT  modules good for 600 volts and 400 amps along with some other junk, mostly capacitors.                                   Dan

Still very nice, a $500 value easily! If only the three phase power to use them were so cheap :) Tim --  Seven Transistor Labs Electrical Engineering Consultation Website:

They are Toshiba MG400G1UL1 Modules.  Obsolete.  In looking for data sheets, I think I found a site with them for $23. But still worth getting.                                             Dan
