Effect of working fluid selection on thermal performance of heat exchanger filled by the porous material

Szymański P.

Journal of Polish CIMEEAC

2015

Vol. 10, no 1

149--154

Thermal management of electronics semiconductor technologies that are located i.e. in a novel marine power plants or computer server rooms become very important issue for designers of such systems. Motivation and need for research in development of novel cooling strategies for modern electronics is of paramount importance. Heat exchangers filled by the porous material are a novel research topic in current heat pipe science. The design of such heat exchangers is rather complex with many things to consider. In this paper the focused is the get knowledge about who to select the working fluid to be used.

Observation of the thermosiphon effect in the circulation of acetone as working fluid in modern cooling system

129--134

Packaging and thermal management of electronic equipment that are located i.e. in a novel marine power plants or computer server rooms has led to the demand for new and reliable methods for electronic cooling. Because of bigger and bigger power levels and miniaturization of the electronic devices, lack of free space in marine power plant, typical cooling techniques such as conduction and forced convection are not able to cool such a high heat flux. The increasing integration of electronic systems requires an improved cooling technology that supposed to be designed for high thermal performance, low mass, and able to work in harsh environments. In this paper presented a prototype of thermosiphon loop heat exchanger developed in Institute of Energy and Industrial Processes in Gdansk University of Technology. This thermosyphon loop is heated from below horizontal side and cooled from upper horizontal side, the working fluid that circulate inside the loop is acetone.
