Introduction: 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.
Step 1: Things You Will Need
1. thick Aluminum foil
3. toothpaste [conductor paste (if possible)]
4. stainless steel wire
7. waterproof box
Step 2: Cut Out Long Stripes of Aluminum Foil
Step 3: Smother the Stripes by Rubbing Any Hard Thing on Them (e.g Blade)
Step 4: 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
Step 5: Add Toothpaste or Conductor Paste(if Available) on the Aluminum Stripes and Then Place the Diode Back in the Aluminium Strip
Step 6: Make a Hole in the Aluminium Stripe From a Pin and Then Tightly Clamp the Stripe Around Diode From a Steel Wire.
Step 7: 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.
