CORREA, Rodrigo; REYES, Oscar  and  MARIN, Jeison. Using a heat pipe (TPTC) for dissipating energy generated by an electronic circuit. Ing. Investig. [online]. 2010, vol.30, n.1, pp.107-111. ISSN 0120-5609.

This paper presents an experimental investigation aimed at estimating the thermal efficiency of a heat pipe compared to the most common elements for removing heat from a circuit (i.e., an electric fan and a fin - extended surface). The input voltage frequency for a standard power circuit was changed for the experiments, whilst all the other parameters were kept constant. An experimental statistical design was used as an analytical tool. Unexpectedly, the heat pipe showed the lowest thermal efficiency for all the experiments, although it had the advantage of being a passive element having low volume and no mobile parts.

Keywords : heat transfer; energy disipated by a circuit; Joule effect.
