Visualization of bubbles formation on the boiling process in tapering heat pipe with variation of evaporator to condenser diameter ratio

“…In the other study, inclination angle affects the thermal efficiency of the heat pipe on working fluid copper using Nano fluid [10]. The studied heat pipe with an inclination angle of 45 o produces the highest thermal performance [11]. The heat pipe design is developed to provide the performance, and heat transfer improvement.…”

“…Wang et al [27] Water/CuO 50 nm & 0.5-2.0 wt.% The inclination angle of 45°corresponds to the best thermal performance for heat pipes Hung et al [15] Water/Al 2 O 3 20 nm & 0.5-3.0 wt.% The tilt angle that maximizes the thermal performance of the heat pipe ranges from 40°to 70°T eng et al [28] Water/Al 2 O 3 20-30 nm & 0.5-3.0 wt.% The optimal thermal efficiency for heat pipes occurred at 60°L iu et al [29] Water/CuO 50 nm & 0.5-2.0 wt.% The inclination angle of 45°corresponds to the best thermal performance for heat pipes Senthilkumar et al [30] Water temperatures of the heat pipe surface were measured using five K-type thermocouples by mounting two thermocouples at the surface of the evaporator, one at the surface of the adiabatic section and the rest at the surface of the condenser section.…”

Experimental Study of Copper Nano-fluid on Thermosyphons Thermal Performance

“…Recently, heat pipes are used to remove intense heat from small electronic components in desktop and laptop computers. Heat pipe is a heat transfer device which transports large quantities of heat with minimum temperature gradient without any additional power between the two temperature limits [8]. A heat pipe consists of essentially three parts: an evaporator, an adiabatic section, and a condenser.…”

“…There is an urgent need for new and innovative coolants with improved performance. The novel heat transfer fluids containing suspensions of nano-particles has been proposed is called ''Nano-fluids'', which are engineered by suspending experimental investigations have revealed that nano-fluids have remarkably higher thermal conductivity and greater heat transfer characteristics than conventional pure fluids [1][2][3][4][5][6][7][8]. In convective heat transfer in nano-fluids, the heat transfer coefficient depends not only on the thermal conductivity but also on other properties, such as the specific heat, density, and dynamic viscosity of a nano-fluid.…”
