A new cooling duct system was developed in order to increase the refrigerator performance in terms of uniform temperature distribution particle image velocimetry (PIV) and the commercial software FLUENT was used to compare the performance of the conventional cooling system with the new cooling system. The new cooling system effectively cooled the door basket region, thus increasing the uniformi...

ARTICLE INFO Cooling of electronics component is one of the major challenges faced by thermal engineers. In recent years, a significant increase in microprocessor power dissipation coupled with CPU size has resulted in an increase in heat fluxes. Microprocessor heat fluxes have also increased for many commercial applications. Therefore, thermal management is becoming one of most challenging iss...

The Neutrino Factory has been proposed as a facility to provide an intense source of neutrinos suitable for the measurement of neutrino oscillation parameters and a possible CP violating phase to unprecedented precision. In the Neutrino Factory, neutrinos are produced by the decay of a muon beam with 20-50 GeV per muon. Initially, the muon beam occupies a large volume in phase space, which must...

Introduction. We sought to compare the performance of endovascular cooling to conventional surface cooling after cardiac arrest. Methods. Patients in coma following cardiopulmonary resuscitation were cooled with an endovascular cooling catheter or with ice bags and cold-water-circulating cooling blankets to a target temperature of 32.0-34.0°C for 24 hours. Performance of cooling techniques was ...

the aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (nepcm) slurry as a cooling fluid instead of pure fluid. a threedimensional model of a circular channel using water slurry of nepcm was developed. the results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...

In this study, effect of adding in SiO2 nanoparticle in base fluid (water) in car radiator is investigated experimentally. Radiators are compact heat exchangers that optimized and evaluated by considering different working conditions. Car\'s cooling system, plays an important role in vehicle\'s performance, consists of two main parts, known as radiator and fan. Radiators are compact heat exchan...

cooling towers are widely used in most industrial units to reject waste heat to the atmosphere. this paper deals with an experimental analysis of heat and mass transfer phenomena between water and air by direct contact in a cooling tower. the tower is filled with 6 type packing. in this study temperature and pressure drop and tower characteristics was used in determining experimentally the ther...

In this study, the thermal performance of the printed circuit board (PCB) as a heat sink for the light-emitting diode (LED) bulb is analyzed. Cooling air is drawn through the bottom inlet of a case and exchanges heat from a vertically aligned PCB acting as a heat sink fin. The air then exits through a top outlet. Cooling performance is improved by arranging parallel PCBs to form a channel. Heat...
