Two-phase thermosyphon loops (TPTLs) are widely used in air-conditioning field for heat recovery and free cooling utilization in recent years. The height difference between the condenser and the evaporator is always considered as the driven force of thermosyphon. However, experiments show the cooling capacity of the TPTLs is not linearly improved with the increase of the height difference. So, ...
Phase change materials (PCM) are applied worldwide as a thermal energy storage technology to reduce demands in buildings and solve environmental contamination issues. Form-stable phase (FSPCM), one branch of PCMs, can be improved by embedding them with thermosyphon, resulting better performance. In this paper, novel thermoplastic elastomer-based FSPCM was developed tested. A device integrating ...
A metallic wire mesh screen, diameter of approximately 50 μm, is folded into ~80 “accordion-shaped” mini-channels and placed inside the evaporator package a novel passive thermal management device for cooling overhead light-emitting diodes (LEDs) used in factory floors high-bay facilities. The power dissipated via these devices ranges between 75 W 171 W. channel walls (screen) wick liquid water...
The energy consumption of air conditioning for a telecommunication base station (TBS) in China can be significantly decreased when an air to air thermosyphon heat exchanger is used for free cooling in low atmosphere temperature days. The model for the typical TBS in China was established and the air conditioning energy consumption was analyzed for the cities with climatic data in China. Taking ...
