Thermal management: Enabling enhanced functionality and reduced carbon footprint

Enhanced energy efficiency and reliability of telecommunication equipment with the introduction of novel air cooled thermal architectures

“…A brief description of one VG embodiment in telecommunications equipment was given in [8] and covered more extensively in [6]. The papers demonstrated that reasonable improvement in heat transfer performance can be achieved if one incorporates small plastic delta winglet VGs upstream of an LFHS.…”

“…Results were presented in [8] comparing all three of the novel monolithic 3D heat sink designs against velocity. The current paper will concentrate on the performance of the one design that is most likely to have a positive impact on telecommunications equipment due to its superior thermal and hydrodynamic performance.…”

“…All of these complex flow phenomena provide insight into the mechanisms of enhanced heat transfer. Since the publication of [8], a prototype has been built and tested on the ATCA v2 platform where the VGs are placed on the board guide rail as previously illustrated in Figure 2c. In this instance, because of design constraints, the VGs are of the delta wing design and they are located directly on the metal board guide rail.…”
