thank you so much for your reply,
amazing cooling technology in laptops isnt it!!!! i'm really surprised to see this. i have seen many videos of laptop tear-down, but never heard from any one that there will be a liquid coolant inside.
will this liquid coolant evaporate with time, do we need to refill them?
will liquid coolant be more effective than normal air cooling with fan and heat sink....
The liquid coolant will never "evaporate". It is completely closed inside of the heatpipe. There actually isn't much liquid in some of the heatpipes. But yes - a heatpipe with liquid cooling is much more effective than air cooling.
