“…Their findings also highlighted a potential scope for optimizing the non-uniform fin height design [4]. Apart from this study, [5][6][7][8][9] illustrated heat transfer aspects of rectangular finned heat sinks for different applications. From the reviewed literature, numerous studies on optimal fin design for maximum heat extraction have been identified.…”

This study investigated the effect of dust deposition on the fin surfaces of a rectangular finned heat sink for natural convection. Therefore, experimental analysis was carried out on two cases, i.e., under fine dust and fiber dust conditions. The experiment was conducted inside a closed duct on the heat sink consisting of 17 fins. After analyzing the data and variation of temperature values at various positions of the fin surfaces, it was observed that the fine dust accumulation had a negligible effect on the thermal performance. However, fiber dust accumulation had a significant effect on the thermal performance. Moreover, the obtained values of Nusselt number were 26.68, 26.21, and 23.75 for natural convection under no dust, fine dust, and fiber dust conditions, respectively. Hence, the amount of heat dissipated by natural convection was minimal under fiber dust conditions.

Experimental investigation on controlled cooling by coupling of thermoelectric and an air impinging jet for CPU

In this study, experimental tests have been carried out on the coupling thermoelectric cooling module with minichannel heatsink subjected to impinging airflow for cooling desktop central processing unit (CPU). A controlled thermoelectric‐forced test system was designed for this purpose. This was designed using electronic Arduino card. The proposed hybrid cooling system was compared with the conventional forced air‐cooling technique. Three power of heat source (CPU) were adopted, investigated, and compared, namely 60, 87, and 95 W. Performance of controlled thermoelectric cooling with three preset temperature were experimentally examined. The effects of air velocity and thermoelectric input current on the case temperature (Tcase), thermal resistance, and heat transfer coefficient were analyzed. Results showed that the Tcase increases with the increase of its input power. In addition, increasing air jet velocity and thermoelectric input current improve CPU cooling significantly. For a CPU power of 95 W, the recorded Tcase temperature was 57°C with the conventional system. While it was maintained below 50°C in the hybrid system. The thermoelectric cooler has had a major effect on CPU cooling, having 15% improvement over conventional forced air‐cooling. However, this was accompanied by an increase in energy consumption in the range of 45 W.

Другое экспериментальное исследование горизонтально расположенного радиатора с прямоугольными ребрами [7] было выполнено при естественной и смешанной конвекции. В работе [8] было исследовано влияние расстояния между ребрами и их высоты на коэффициент теплоотдачи.…”

Study of thermal characteristics of the radiator with vertical finning using aerosol evaporative cooling

2020

View full text Add to dashboard Cite

The paper is dedicated to the new cooling scheme examination where aerosol is injected directly into the air-cooling system and then the evaporated aerosol is collected and redirected back to the inlet ports. It has examined the air-and-water aerosol influence on the heat extractor characteristics and area of the cooling surface of radiator with parallel square fins considering natural convection as well as radiation. Also, the influence of different characteristics has been examined, such as the concentration of water in aerosol, input power of heating, on the characteristics of the heat extractor.
