Abstract A theoretical study is conducted to investigate a new cooling technique for thermal management of outdoor telecommunication equipment enclosures. The technique consists of using a phase change material (PCM) combined with a heat sink to dissipate the heat to the ambient. The main advantages of using the PCM include: fully passive technique with no maintenance, no power is required, and relatively low cost. The use of the PCM for more effective thermal management of electronic enclosures is investigated for both the high end cooling (i.e. when the enclosure is exposed to high ambient temperatures) and the low end cooling (i.e. when the enclosure is exposed to very low ambient temperatures). The results from this preliminary theoretical study showed that with the use of a moderate amount of a properly selected PCM combined with the heat sink, the temperature within the enclosure can be maintained within the specified operating range. Potential applications with the use of the PCM include: peak load usage (e.g. during high communications traffic periods), extreme ambient conditions, reduced temperature fluctuations (to improve reliability), and more efficient implementation in smaller size enclosures.

Abstract In recent years phase change materials (PCMs) have emerged as a promising material for various thermal management applications. However, the lower thermal conductivity of PCM is a major hindrance in its widespread use. In the present study, an experimental investigation is carried out using high thermal conductive carbon foam (CF) embedded with PCM inside heat sink for thermal management of electronic components. Various configurations of heat sinks such as unfinned heat sink without PCM, unfinned heat sink integrated with PCM, unfinned heat sink integrated with CF-PCM composite, two finned heat sink integrated with PCM, and two finned heat sink integrated with CF-PCM composite are investigated. The vacuum impregnation technique is employed to infiltrate the PCM inside the CF. Heat flux is varied in the range of 1.5 to 2.5 kW/m2. Temperature variation of the heat sink base is used to compare the performance of various heat sinks. Unfinned heat sink without and with PCM is used for baseline comparison. Enhancement ratios are presented for various set point temperatures (SPT) such as 65 and 75°C. The highest enhancement ratio of 4.98 is obtained for two fin CF-PCM composite heat sink.
