Heat Sink for Diodes

Where ever i want to reduce voltage i use rectifier diodes (1N4007), but the problems is that they get too much hot on passing too many ampere through them which may damage them. The only solution i found was to create heat sink to keep them cool.

I used 2 series pair of 2 diodes, connected parallel and attached my heat sink on them. Believe me or not my diodes worked fine even on passing 12 volts and 15 amperes through them.

Things You Will Need

1. thick Aluminum foil

2. diodes

3. toothpaste [conductor paste (if possible)]

4. stainless steel wire

5. pin

6. scissors/cutter

7. waterproof box

Cut Out Long Stripes of Aluminum Foil

Smother the Stripes by Rubbing Any Hard Thing on Them (e.g Blade)

Wrap the Aluminum Stripes Around the Diode (as Shown in the Picture), But Then Pull Out or Unwrap the Foil in Such a Way That the Shape of the Diode Stays on Them

Add Toothpaste or Conductor Paste(if Available) on the Aluminum Stripes and Then Place the Diode Back in the Aluminium Strip

Make a Hole in the Aluminium Stripe From a Pin and Then Tightly Clamp the Stripe Around Diode From a Steel Wire.

Congratulation ! You Have Made a Diode Heat Sink.

Now it depends upon you whether to dip the heat sink in water or you place it in a ventilated box.
