“…The result stated that after thermal tests, the loop heat pipe improves power and heat transfer-distance significantly without additional energy source (Maydanik et al, 2018). The effect of the heat pipe effective length also affects the velocity of the mass flow rate along the pipe, which also affects the final heat dissipation generated by the CPU (Muhammaddiyah et al, 2018;Winarta et al, 2019). Tan et al (2005) conducted an analytical study of flat plate heat pipe effective length using a point source approach.…”

Computer Central Processing Unit (CPU) technology is being developed rapidly for better work performance together with smaller size. This technology development produces significant heat flux increase on the processor. In this paper, a cascade straight heat pipe (CSHP) is created for a better CPU cooling system which is a fully passive system using nanofluids and hybrid nanofluid as the working fluid. Heat loads were given to the CSHP at 10 watts, 20 watts, 30 watts, and 40 watts, respectively. Based on the experiment's result, the CSHP with Al2O3-TiO2-water working fluid showed the best performance, decreasing 41.872% of the simulator plate temperature at maximum load while also having the highest condenser output temperature. The CSHP with Al2O3-water working fluid decreased 35.243% of the simulator plate temperature. The CSHP with water working fluid decreased only 28.648% of the simulator plate temperature and had the lowest condenser output temperature. The CSHP with Al2O3-TiO2-water showed the lowest thermal resistance and the highest coefficient of heat transfer.

“…The heat pipe is thus a beneficial device within energy recovery systems (Srimuang & Amatachaya, 2012). Several types of heat pipes have been applied, such as straight heat pipes (Putra et al, 2017), thermosyphon (Jouhara & Merchant, 2012), oscillating heat pipes (Winarta et al, 2019), and a wraparound loop heat pipe (Jouhara & Meskimmon, 2018). An HVAC system with an HPHE installed provides the benefit of acting as heat recovery equipment, mainly when used in the operating room of a hospital (Shabgard et al, 2015).…”

Hospitals consume large amounts of energy, especially in their heating, ventilation, and air conditioning (HVAC) systems due to the special requirements for ensuring healthy, comfortable, and safe environmental conditions. The use of a Heat Pipe Heat Exchanger (HPHE) is recommended as a means of minimizing electricity consumption with no loss of comfort while also improving indoor air quality. An experimental study was conducted to investigate the performance of a U-shape HPHE in recovering exhaust air heat from an indoor room included in an HVAC system. The U-shape HPHE consists of several tubular U-shape heat pipes with water as a working fluid and arranged in a staggered configuration. Tests were carried out to determine the impact of the inlet air temperature, air velocity, and the number of heat pipes on its effectiveness. The experiment revealed that the higher the temperature of the inlet air, the more effective the U-shape HPHE. The results show that the temperature of the air entering the cooling coil decreased by 1.73 °C with an effectiveness value of 7.64 %. This result was achieved using 12 U-shape HPHEs, which had a staggered arrangement, an air velocity of 1.5 m / s, and an air temperature entering the evaporator of 45 °C. The highest amount of heat recovery, 2190.43 kJ/hour, was achieved when the air velocity was 2.5 m/s.
