Abstract: Anodization of micro fins in the heat pipes forms a thin porous layer and increases the capillary pressure by decreasing the minimum effective capillary radius. The increase in capillary pressure ensures adequate circulation of working fluid from the condenser to the evaporator and vice versa, leading to higher heat transfer between the two ends of the heat pipe. The anodized micro finned heat pipe can work in anti-gravity, which could apply to satellite cooling applications. It has been observed that the heat pipe with anodized micro fin transferred over 35W in an anti-gravity direction. Generally, anodization is used as a protective coating; however, in this patent, anodization is used to improve heat transfer.

Abstract: Generally, the chilling units were used in all coolers to remove the heat from the water and to decrease the temperature using a mechanical refrigeration system, which is costly, consumes power, and is heavy. Therefore, cost-effective chillers are the need of the hour for everyone and should be affordable for even economically weaker sections. Hence, this patent adopts a bubble-cooling method to cool the water. The principle of the bubble cooling method is to transfer heat from the water to the surroundings by evaporating a minor quantity of water by creating bubbles in the fluid. The generated bubbles rise to the surface and carry away heat from the water through a combination of convective and evaporative heat transfer during the bubble collapse. As the bubbles burst at the surface, the heat is released into the surrounding air or environment, completing the cooling process, reducing the temperature of water. Bubble cooling has several advantages over traditional cooling methods. It can achieve high heat transfer rates and low thermal resistance, resulting in more efficient and effective cooling. It can also operate at low-pressure drops, reducing the energy required for pumping and minimizing the risk of system failure
