“…To date, heat pipes can be fabricated in many different types, including thermosyphons 9 , capillary heat pipes 10 – 12 , loop heat pipes 13 , 14 , miniature heat pipes 15 and oscillating heat pipes 16 – 20 . Owing to their advantages of high thermal conductivity and low cost, capillary heat pipes have been widely applied within field likes electronics 21 , aerospace 22 , solar heating water systems 23 – 25 and battery thermal management 26 , 27 . In the capillary heat pipe, the wick structure (as the most important component) not only provides a significantly efficient capillary force to pump condensed liquid back to the evaporator section, it also increases the heat transfer area of the evaporator and condenser sections, which will further affect the heat transfer performance of the heat pipe.…”

As the electronic technology becomes increasingly integrated and miniaturized, thermal management has become a major challenge for electronic device applications. A heat pipe is a highly efficient two-phase heat transfer device. Due to its simple structure, high thermal conductivity and good temperature uniformity, it has been used in many different industrial fields. A novel aluminum flat heat pipe, with micro-grooves, has in the present work been designed and fabricated by using a 3D printing technology. Aluminum powder was used as a raw material, which was selectively melted and solidified to form the shape of the heat pipe. The sintered aluminum powder increased the roughness of the inner surface of the heat pipe, and the designed micro-grooves further enhanced the capillary forces induced by the wick structure. The wettability, for the working fluid (acetone), was excellent and the capillary forces were sufficient for the working fluid to flow back in the pipe. The effects of working fluid filling ratio, on the heat transfer performance of the heat pipe, was also investigated. It was shown that a filling ratio of 10% gave the best heat transfer performance with the lowest thermal resistance. The 3D-printed flat heat pipe was, therefore, also tested for the thermal management of a LED. The temperature of the LED could be kept within 40 °C and its service life became prolonged.

“…Depending on the source of driving force for condensate return inside the heat pipe, heat pipes can be distinguished into rotating and non-rotating heat pipes. The non-rotating heat pipe is driven by capillary force or gravity 4 , while the condensate return in a rotating heat pipe is achieved by the rotational motion of the heat pipe body 3 .…”

In the last decade one of the main opportunity areas of the cooler systems is increase their efficiency; for this, it has been innovating in materials and working fluids mainly. In the last decade one of the main areas of opportunity in refrigeration systems is the reference to increase their efficiency. For this, it has been innovating in materials and fluids of work mainly. In this work, the analysis of the transfer of calories in liquid cooling systems is analyzed by adding nanoparticles. These systems have different industrial and refrigeration applications in electronic systems. In the present work a configuration of the refrigeration system to be used is proposed. The analysis consists of the mathematical mode from the design of the geometry and the trajectory of the flow in the pipeline, in addition to a simulation in Computational Fluid Dynamics (CFD) of the system. The conditions are presented in the results.
