“…For instance, a 20 MW data center necessitated cooling water in a quantity that can be used by 2500 people [7]. Moreover, liquid cooling can be effective for the thermal management of the electronic components of electric vehicles, such as power modules [8][9][10][11], insulated-gate bipolar transistors [12][13][14][15], and battery packs [16][17][18].…”

This paper reviews the major researchers of liquid, immersion, and two-phase cooling. Currently, liquids are used instead of air to cool the growing data centers. Immersion cooling shows a higher heat transfer coefficient than conventional cooling (<37 W/cm2). Because the use of liquids with high global warming potentials is prohibited, the number of liquids that can be used is limited. This paper discusses the existing, relevant literature from researchers who have studied the issue at least thrice. The authors were divided into those who focused on the surface and those who formed a structure on the surface. In summary, the authors suggested the following research directions: The experimental conditions of porous foam are not diverse, and there is a concern about the separation of foam and coating into the tub. The experimental conditions of the immersion tub should also be varied according to the heat and pressure over time. Structure-level research shows higher performance than surface-level research, but an economic feasibility study is required.

“…The redesigned mini‐channel heat sink's coolant distribution reduces the temperature gradient by 60%. Deng et al, 28 have done experimental and theoretical analyses of a hybrid mini‐channel and slot jet array heat sink to understand the flow and heat transfer characteristics. The applied heat flux was 35.74 W cm −2 and 62.22 W cm −2 , at different flow rates ranging from 0.1 L min −1 to 1.2 L min −1 and both the heat sinks have a length and width of 10 mm and height of 2 mm.…”

Summary The cogenerated energy from the densely packed ultrahigh concentration photovoltaic thermal systems (UHCPV/T) can not only promote higher exergetic efficiency but also enable the usability of the collected thermal energy for potential desalination purposes. In the present study, three finned heat sink designs of UHCPV/T have been proposed toward maximum collected thermal power and minimum required pumping power. A conjugate heat transfer model has been developed and validated to simulate the different designs under various operating conditions. The cooling setups are based on copper millimeter‐scale finned heat sinks immersed in fully developed laminar flow in a rectangular microchannel. It was found that the configuration from the more efficient heat sink design to the poorest thermal one is the rectangular fins (RFs), elliptical fins (EFs), diamond pin‐fins (DPFs), and then traditional round pin‐fins (TRPFs) heat sink. The RF heat sink has demonstrated the best thermal performance with a maximum multi‐junction solar cell (MJSC) temperature of 81.4°C and water temperature increase of 14.21°C under ×1200 and water inlet velocity of 0.02 m/s. Despite the RF heat sink has recorded the highest values of pressure drop and required pumping power equal to 78.74 Pa and 570.7 mW, respectively, it was selected as the optimal heat sink design, ensuring the highest net electrical output power and thermal collected power.
