Abstract
Micro heat pipes are devices that work by transporting heat through the phase change of a working fluid inside of an enclosure that has acute angles in its cross section to pump the liquid by capillary effect. The possibility of different combinations of micro heat pipes parameters, such as material, dimensions, geometry, inclination, filling ratio, working fluid type, led to a wide number of studies through the past decades. Therefore, a brass micro heat pipe array was analyzed in the present study. The array consisted of 40 triangular micro channels with 500 µm side length, 105 mm long and 500 µm interchannel spacing. R134a was utilized as working fluid. The thermal performance was measured by values of effective thermal conductivity and thermal resistance of the filled and empty array. The micro heat pipes enhanced the heat transport of the system.
