Heat pipes have the advantage of transferring large amounts of heat between reservoirs with small temperature differences which makes them preferable for electronics cooling applications. Micro-grooved heat pipes promise the additional advantage of being adaptable to systems which need to be cooled with minimal contact resistance. In this study, a multi-physics computational model is developed to assess the thermal performance of a silicon-based micro-grooved heat pipe. The microfluidic platform consists of 50 rectangular micro-grooves on a silicon wafer with integrated chromium (Cr) microheaters. The phase change occurring within the micro-groove is included in the model as a convective heat transfer boundary condition at the channel wall. The convective heat transfer coefficients are obtained from another detailed study in which the 3-D heat transfer process in the solid and working fluid coupled with a 1-D analysis of momentum equation in a unit cell is solved. With the current computational model, an experimental set-up is designed, which will be used as the verification tool of the detailed computational model for a unit cell. The required heating and cooling conditions of the unit cell model can be realized with the proper design of the heater and the cooling channels. The present study demonstrates that the thermal performance of MHP can be predicted with global multi-physics modeling integrated with rigorous phase change model based on a unit cell.

Multi-dimensional modelling of evaporation in the micro region of a micro grooved heat pipe Akkuş, Yiğit; Dursunkaya, Zafer; Tarman, Işık Hakan; Department of Mechanical Engineering (2015) Capillary cooling devices are preferred in heat removal from electronic components which are characterized by high heat dissipation rates. Heat pipes use various wick structures to generate the necessary capillary action. Heat pipes that use grooved micro-channels as wick structures, have been widely studied by researchers due to the fact that their simple geometry enables the modelling of fluid flow and heat transfer both analytically and numerically. Near the attachment point of liquid-vapor free surface ...
Modeling guided heat pipe design methodology and experimental validation for flat grooved heat pipes Saygan, Samet; Dursunkaya, Zafer; Çetin, Barbaros; Department of Mechanical Engineering (2021-2-24) Heat pipes are commonly preferred thermal management devices due to their rapid heat transfer characteristics, small size and reliability. It is crucial to design heat pipes that accurately match the requirements of the system to be thermally managed. In the present study, a numerical design and diagnosis simulation tool for heat pipes is developed and verified for grooved heat pipes. A modular heat pipe experimental setup is designed and manufactured. In order to decide on the geometric parameters of the h...
PERFORMANCE ASSESSMENT OF COMMERCIAL HEAT PIPES WITH SINTERED AND GROOVED WICKS UNDER NATURAL CONVECTION Atay, Atakan; Sariarslan, Busra; Kuscu, Yigit F.; Saygan, Samet; Akkus, Yigit; Gurer, A. Turker; Cetin, Barbaros; Dursunkaya, Zafer (2019-01-01) Heat pipes are widely used in thermal management of high heat flux devices due to their ability of removing high heat loads with small temperature differences. While the thermal conductivity of standard metal coolers is approximately 100-500 W/m.K, effective thermal conductivities of heat pipes, which utilize phase-change heat transfer, can reach up to 50,000 W/m.K. In industrial applications, commercially available heat pipes are commonly preferred by thermal engineers due to their low cost and versatility...
Modeling of multidimensional heat transfer in a rectangular grooved heat pipe / Odabaşı, Gülnihal; Dursunkaya, Zafer; Department of Mechanical Engineering (2014) Heat pipes are generally preferred for electronics cooling application due to large heat transfer capacity in spite of small size. Micro heat pipes use small channels, whose dimension is on the order of micrometers, to generate necessary capillary action maintaining fluid flow for heat pipe operation. In the present study a flat micro heat pipe with rectangular cross section is analyzed numerically. A simplified axial fluid flow model is utilized to find liquid-vapor interface shape variation along the heat...
Performance analysis of grooved heat pipes using 3-D multi-channel thermal resistance network Sezmen, Ramazan Aykut; Dursunkaya, Zafer; Çetin, Barbaros; Department of Mechanical Engineering (2021-9) Heat pipes are phase change heat transfer devices that transfer high amounts of heat with low temperature differences compared to conventional cooling techniques due to their high thermal conductivity. Since heat pipes do not require any external power supply and not involve any moving parts, they are preferred for high reliability applications and in wide range of industrial applications from thermal management of electronics to space applications. Essentially, heat pipes use the advantage of occurring pha...
