“…Researchers have carried out lots of numerical simulations of forced single phase water flowing in heat sinks with different physical dimensions, concluding that the predicted results agree well with the experimental data [24][25][26]. In the mentioned numerical simulations, finite volume method (FVM) is widely used to solve the conjugate heat transfer problem for simultaneously predicting of the temperature fields in the solid and liquid regions.…”

A coupled finite volume-element method is developed to simulate the transient thermal deformation of water-cooled mirror by considering fluid flow and convective heat transfer. The simulation process consists of two steps: the 3D finite volume models of fluid flow and heat transfer equation are solved to obtain the time-dependent temperature field by using CFD; then, the obtained temperature field used as final temperature field is unidirectionally coupled to the finite element model for solving the thermoplastic equation. It is concluded that fluid flow not only affects the magnitude of temperature rise and thermal deformation, but also affects the distribution of temperature and thermal deformation. The temperature gradient in the thickness direction (z direction) is found to be much larger than that in transverse direction. It is found that the temperature and the consequent deformation of water-cooled mirror increase significantly in the first seconds and gradually become steady state in the subsequent time. Experiments are conducted to estimate the precision of numerical models, and the experimental results agree well with the simulated results.

“…At the same time, this reduction in physical space is counterweighted by the high performance required at the refrigeration systems in such equipment. Therefore, thermal control is one of the most critical areas for the development of modern microelectronic devices [1][2][3][4][5].…”

“…A lot of experimental studies [1,2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], besides theoretical [22][23][24] and numerical studies [5,[25][26][27][28], have been carried out, in the past decades, seeking to investigate the hydrodynamics and heat transfer characteristics in microscale. The results obtained in several of these studies show diversions among themselves and, also, with the conventional theory.…”

“…Some researchers attribute the deviations found for the friction factor or Poiseuille number to variations of the cross-section of microchannels due to the surface roughness [6,12,14,17]. Other researchers attribute these deviations to deformations existing in the cross-section of the microchannels [2,21], to aspect ratio of channels [2,5,8,17] and, also, to scaling effects, such as viscous dissipation [19,26] and electrokinetic effect [22,23], for example. Uncertainty analysis carried out in several experimental studies attribute to the inaccuracy in the measurement of hydraulic diameter of the microchannels as one of the main reasons of errors in determining the friction factor and Poiseuille number in microscale flow [1,16,[19][20][21].…”

“…However, other researchers have indicated that differences in rates and coefficients of heat transfer, as well as in Nusselt number, can be related to the flow velocity and fluid temperature [16,[34][35][36], the Reynolds number [9], the heat transfer conjugated [2,[37][38][39], the viscous dissipation [16,20,26,40,41], the surface roughness [42], the aspect ratio of microchannels [5,43] and the conductivity of the material that compose them [2,[37][38][39], besides experimental uncertainties [4,[30][31][32][33]44]. Some numerical studies [45,46] showed that the Nusselt number is more sensitive to the shape of the cross-section of the microchannels in comparison to other parameters, such as surface roughness, for example.…”

A significant quantity of research has been dedicated to the application of liquid cold plates to eliminate the high heat flux in server electronic chips. Traditional parallel straight microchannel liquid cold plates suffer from low heat flux density with uneven flow distribution, which poses a serious challenge to high-performance server chip heat dissipation. This paper reviews recent research progress in geometry optimization, interrupted structures, channel patterns, and two-phase flow of liquid cold plates. The optimal geometry parameters of rectangular cross-sectional microchannels including the aspect ratio, length, and hydraulic diameter are summarized. Inquest of higher thermal performance, various interrupted structures (ribs, pin fins, etc.), special channel patterns (wavy-shaped, zigzag-shaped, fractal, serpentine, and doublelayered microchannels, etc.), and two-phase flow on the liquid cold plate are applied to promote fluid-turbulivity and increase heat transfer area, meanwhile they lead to more pressure drop. Furthermore, it is an essential approach to commercialize liquid cold plates by applying the academic and prototype of the liquid cold plate to manufacturing and liquid cooling system solutions. In the end, this review provides a discussion about the limitations of current research on liquid cold plates and an outlook on future research directions.
