Over the last 4 years, the loop heat pipe (LHP) technology has been under development by this institute, focusing on future applications for this passive thermal control device, specially related to instruments' thermal control in satellites. Such a development has been focused on designing, manufacturing, assembling, charging and testing LHPs for Space applications using acetone as working fluid. Several procedures were specially conceived during the development program, which resulted in reliable apparatuses that have been extensively tested for potential applications. Repeatability on the processes used during the manufacturing of the LHPs was established as the key parameter to qualify this technology, as well as suppliers and techniques for charging and testing procedures. As a result, several LHPs were manufactured and are operational presenting reliable results related to the thermal control, according to the parameters established by the project. In parallel, two mathematical models were developed based on the experimental data gathered in laboratory conditions, which were then validated and have been applied on the design of LHPs for Earth orbit operation.
