Solid‐state high voltage high repetitive pulse generators have a broad prospect in various applications. The high power and high‐frequency operation of the pulse generator suffer from the massive heat dissipation problem, which limits the improvement of the output parameters and even affects the lifetime. This article focuses on heat management technology for high voltage high repetitive pulse generators. Firstly, the typical circuit topology of the high repetitive pulse generators was summarised. From the perspective of different application requirements, the demands of the heat management design were concluded. Moreover, the heat generation characteristics and difficulties of solid‐state high voltage high repetitive pulse generators were analysed. Then, the different state‐of‐art cooling techniques were reviewed, and their applicability and limitations for the high voltage high repetitive generators were discussed. Finally, a flow chart for heat management design was given.

“…Unlike beam fans, generating airflow in open space, diaphragm pumps require at least one chamber to create the pressure, and thus, the airflow. Despite diaphragm pumps are flexible in the chamber design, the performance of a diaphragm pump depends on factors such as the operating conditions of the PE actuator [57,58], the configuration of the chamber [57][58][59], and the structure of the inlet and outlet [60,61].…”

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.

“…Fewer studies have investigated the use of SJs for actual cooling applications. For example, De Bock et al [23] and Marron et al [24] explored the performance of SJs for heat sink cooling. These studies showed that SJs can provide significant cooling enhancement over natural convection and that under certain conditions, they outperform traditional fans, especially for equivalent power requirement.…”

To address the growing energy use of data centers, waste heat recuperation offers a solution to better integrate these facilities into the broader energy system, thus facilitating a transition to the decarbonization of the energy system. The use of liquid coolants for full immersion cooling or local heat extraction from high power density components is considered for this purpose. However, heat can also be extracted by novel air cooling approaches, perhaps in combination with localized liquid cooling. To optimize heat extraction from air-cooled systems and maximize the heat grade, synthetic jets can be used for targeted adaptive cooling in conjunction with air ducting to facilitate maximum heat recuperation potential in rack or server-mounted air-to-liquid heat exchangers. Internal server layouts can be optimized numerically, e.g., using a multiple objective genetic algorithm approach based on minimization of entropy generation rates.However, since synthetic jets are inherently transient flow phenomena, this would require transient flow simulations, which form a bottleneck in a numerical optimization loop. This research aims to develop a simplified steady-state representation of a synthetic jet actuator (SJA) with slot orifice using a localized body force to generate a similar time-averaged flow field to a real SJA, suitable for steady Reynolds-averaged Navier Stokes simulations within a numerical optimization loop. Both flow fields are compared in terms of the mean flow field, jet spreading rate, and turbulence intensity distributions.
