“…Qu et al [78] demonstrated a needle-to-ring EHD pump used to cool a 10 W ligtht-emititng diode (LED) that comes with a heat sink and showed the maximum temperature difference at the heating film center between the cases with and without the EHD pump could be 35.6 C. Feng et al [79] presented a needle-to-plate EHD pump, where the plate is the fin of the heat sink, and reported that the maximum temperature drops from 54.5 C to 39.1 C for a 7.2 W heat source while the EHD pump consumes 0.85 W power only. He et al [80] proposed a wire-toplate EHD pump for a thermoelectric refrigeration system and reported that the EHD cooling system makes the coefficient of performance of the refrigeration system similar to that using traditional mechanical fans while the noise level is only 4.2 dbA (Fig. 35).…”

“…Besides, EHD flow is also known to be useful in the boundary layer control [89,90], and thus the heat transfer enhancement [91,92]. Furthermore, EHD pumps have no moving parts, making the silent operation possible [80,93]. However, EHD pumps suffer from performance degradations because of the oxidation on corona electrodes [94,95], even coating nanomaterials (e.g., monolayer graphene and single-walled carbon nanotubes) onto corona electrodes could ease such the problems [96].…”

For electronics, poor thermal management could cause severe mechanical and electrical failures. Forced convective air cooling, i.e., flowing air over a hot surface, is one of the most efficient and economical solutions to manage thermal issues of electronics. Air pump is used to initiate and sustain airflow required in forced convection. This paper reviews both the mechanical and the nonmechanical air pumps that have been using widely in current electronics or have a great potential in future electronics. The mechanical pumps include axial fans, blowers, beam fans, and diaphragm pumps, while the nonmechanical pump specifically focuses on electrohydrodynamic pumps. This paper presents the working principle first and then the recent developments, including the pump itself (design, characteristics, etc.) and the applications in thermal management (placement, integration, etc.). In the end, this paper conducts the strength analysis (flow rate, pressure, noise, flexibility, and reliability) among the reviewed five types of air pumps.

“…Since the 19th century, the rise of the Industrial Revolution has led to an explosive increase in demand for fans. Fans are widely used in industries such as metallurgy, chemical engineering, petroleum refining, natural gas, and refrigeration [2] . Besides, fan is one of the most important auxiliary-equipment in power generation stations.…”

To overcome the technical challenges of the multi-blade centrifugal fan, such as low efficiency and insufficient total pressure, the single-arc blades of the fan were optimized and replaced in this study. The flow field of the multi-blade centrifugal fan with a single-arc blade and an airfoil blade was simulated and compared using Computational Fluid Dynamics (CFD). Under steady-state conditions, the total pressure, velocity field distribution, and aerodynamic performance of a multi-blade centrifugal fan were analyzed. The numerical results show that the presence of vortices, secondary flows, and boundary layer separation in the flow channel of a single-arc multi-blade centrifugal fan. Combined with the lift-to-drag ratio theory of aerodynamic airfoil, four different airfoil blades were selected for the multi-blade centrifugal fan. It can be found that the lift-to-drag ratio of the airfoil was positively correlated with fan efficiency. Furthermore, the airfoil blade can suppress the above phenomena in the flow channel and enhance the flowability of the blade flow channel. Verified experiments on airfoil effects showed a 3%-7% efficiency improvement in the multi-blade centrifugal fan compared to the single-arc blade. Additionally, the airfoil fan exhibited substantial enhancements in total pressure and power. These findings hold significance for guiding optimal fan design.

“…Astrain et al [8] studied the combined thermoelectric and vapor compression hybrid refrigerator. The efficiency of a system with ionic wind fans has been developed [9]. Electronic devices generate much heat during operation, so the maximum junction temperature should be maintained below 85℃ [10], and the maximum generated heat is about 200W [11].…”

This work presents the COP and EER of the combined air conditioning and thermoelectric cooling systems. The small-scale air conditioning (8000 BTU/hr) with thermoelectric cooling systems is set up in the closed room (2.0*2.0*2.0 m), and free energy from the photovoltaic cell is used for the thermoelectric cooling module. The COP and EER with the thermoelectric cooling module are higher than those without the thermoelectric cooling module. It is observed that the COP and EER increase as the axial fan speeds increase. In addition, there is good agreement from the comparison, giving an average error of 3.77%. The highest COP and EER for the system with the thermoelectric cooling module are 1.71 and 5.85 for an airflow rate of 4.7 m3/s, respectively. The results can be used as guidelines for developing the thermal performance of air conditioning by combining it with the thermoelectric cooling module.
