             abstract = "Important applications can be found on surveillance systems using 
                         high performance thermal control devices, especially passive ones 
                         using heat pipe technology. With the growing need for heat 
                         dissipation presented by this type of system, usually hybrid 
                         solutions are designed. This 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. 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 can find 
                         many other applications in 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 (PHPs) becomes the most 
                         indicated solution for the present investigation, together with 
                         the use of heat pipes for proper heat rejection. Based on this 
                         fact, this investigation is focused on presenting the thermal 
                         control management of electronic components of a surveillance 
                         system being done by PHPs configured as open loops with 
                         conventional heat pipes. Despite the relatively high temperature 
                         difference observed between the heat source and the sink (up to 25 
                         °C), the open loop PHP was able to transport the rejected heat (up 
                         to 40 W) from the electronic components to a remote heat 
                         dissipation area, while keeping their temperatures within the 
                         required range established by the project (below 80 °C) and 
                         relatively high thermal conductances (up to 1.6 W/°C), as 
                         demonstrated by experimental results. The heat pipe has 
                         demonstrated the capability of spreading the heat evenly, 
                         positively affecting the operation of the PHP. The operation of 
                         this combined solution has shown to be stable and reliable.",
