             abstract = "Surveillance systems have proven to be important applications for 
                         high performance thermal control devices, especially the passive 
                         ones using heat pipe technology. With the growing need for heat 
                         dissipation presented by this type of system, usually hybrid 
                         solutions are designed, which include both liquid cooling and 
                         passive two-phase thermal control. This last one is usually 
                         applied when the heat source is located far from the heat sink and 
                         the use of liquid cooling or any other active thermal control 
                         system is not possible due to the lack of available space for 
                         integration. Since most of the surveillance systems being designed 
                         today require thermal control devices that operate under adverse 
                         orientation, some restrictions apply. Therefore, the technology 
                         that is currently used and disseminated for aerospace missions can 
                         find many other applications on surveillance systems for defense 
                         purposes. With severe restrictions regarding available space for 
                         integration of common thermal control devices, the design and 
                         application of pulsating heat pipes become the most indicated 
                         solution for the present investigation. Previous investigations 
                         have demonstrated that pulsating heat pipes configured as an open 
                         loop can operate on adverse conditions, promoting the heat 
                         transport from the source to the sink with good reliability. Based 
                         on this fact, this investigation is focused on presenting the 
                         thermal management of electronic components of a surveillance 
                         system being done by pulsating heat pipes configured as open 
                         loops. Despite the relatively high temperature difference between 
                         the heat source and sink, the open loop pulsating heat pipe is 
                         able to transport the rejected heat from the electronic components 
                         to a remote heat dissipation area, while keeping their 
                         temperatures within the required range established by the project. 
                         The operation of the pulsating heat pipes have proven to be stable 
                         and reliable, meeting the project's expectations for thermal 
                         control.",
