Design of a Heat Sink for an Electronic Component in ABB Drive using Different Types of Fins

As the computing frontier drifts to the edge, edge datacenters play a crucial role in supporting various real-time applications. Different from cloud datacenters, the requirements of proximity to end-users, high density, and heterogeneity, present new challenges to cool the edge datacenters efficiently. Although warm water cooling has become a promising cooling technique for this infrastructure, the one-size-fits-all cooling control would lower the cooling efficiency considerably because of the severe thermal imbalance across servers, hardware, and even inside one hardware component in an edge datacenter. In this work, we propose CoolEdge, a hotspot-relievable warm water cooling system for improving the cooling efficiency and saving costs of edge datacenters. Specifically, through the elaborate design of water circulations, CoolEdge can dynamically adjust the water temperature and flow rate for each heterogeneous hardware component to eliminate the hardwarelevel hotspots. By redesigning cold plates, CoolEdge can quickly disperse the chip-level hotspots without manual intervention. We further quantify the power saving achieved by the warm water

In this study, two types of heat sinks are selected at similar dimensions. In addition, five types of aluminum alloys are used to find the optimum performance for both models’ inline and cut cross heat sinks. These types of alloy materials were Al-1100, Al-3063, Al+25%Ni, and Al+25%Cu that are selected and compared with pure aluminum. The effectiveness results showed of the heat sink using Al- 25%Cu has the highest value compared to the other material types Al- 25%Ni, Al 1100, and Al 6063 respectively. While the lowest value of the fin efficiency was observed for pure aluminum. Moreover, the heat sink using Al- 25%Ni, Al 1100, and Al 6063 has moderate values. The results also indicated that the rate of heat-dissipated from the cut cross heat sink increases, as the fin thickness increases until reaches maximum value be-fore it decreases with an increase in the fin thickness. While for the inline heat sink, the heat transfer increases as the fin thickness increase before stables at 2 mm approximately.
