Extensive Development of the Loop Heat Pipe Technology 2006-01-2169
The development of LHPs for space applications have shown the possibility of using them in several ground applications, such as water heating systems, electronics cooling, etc. Some issues related to the use of LHPs rely on their design and development depending on the required use. In this case, the most indicated configuration for their reliable operation will depend on the correct selection of working fluid, materials and configuration regarding the maximum heat management requirement. This paper presents what has been developed in this institute regarding the LHP technology, which includes devices for electronics cooling operating at its classical design (one evaporator and condenser), reversible, ramified and miniature LHPs. The results obtained have shown the great potential in using LHPs as passive thermal control devices. Continuous development have shown that the LHPs can promote a reliable control of the heat source temperature within the required designed limits, even when considering the issue of miniaturizing these devices.
