Question
QUESTION: Dear ZZ

Is it feasible to install Heat sink fan within Smartphone?.

Thanks
Prashant

ANSWER: It would be very difficult since there is no room inside; they are packaged so tightly to keep them small and efficient.  The IC chip is intentionally mounted so as to dissipate heat to the outer case; thus getting a little warm to the touch but that is the way the heat is drawn out.  Holding a smartphone in ones hand will warm the hand but it will also help carry the heat away from the phone.

Hope this helps.

QUESTION: Dear ZZ

Thanks.

Do you feel if this is made possible with robust engineering design in Smartphone, will there be advantages in implementing Heat sink fan?.

Thanks
Prashant

Answer
I see no advantage in adding a fan to the smartphone.

First there is no space and increasing the size to accomodate a fan is out of the question.

Secondly the already low battery power would be shortened even further which would be a big negative to the selling story of the phone. Battery power is one of the principle targets of new designs; every user wants more battery running time, not less (which would be caused by an addition of a fan).
