LABTUCAL will participate in the next two missions aboard the VSB-30 suborbital rocket, from the Microgravity project (4? and 5? Announcement of Opportunities) financed by the Brazilian Space Agency (AEB). The design allows different heat pipe configurations to operate in a Microgravity environment. The suborbital rocket will be launched from the Alc�ntara Rocket Launch Center in Brazil. This project deals with the design, manufacture and testing of devices dedicated to the thermal control of satellite electronic equipment, but applying new porous media technologies for mini heat pipes, heat pipes in circuits (LHP - Loop Heat Pipe) and heat pipes. pulsating heat pipe (PHP- Pulsating Heat Pipe). These devices are superconductors of heat, which use phase change of a working fluid and capillary action to passively transport heat from a hot source to a cold source. The working fluid circulates through the action of capillary forces generated by the porous element present in the evaporator section, which is responsible for pumping the condensate from the condenser section to the evaporator section. The effect of microgravity can influence the operation of devices based on phenomena involving phase change, surface tension and fluid flow. For this reason, testing these devices in microgravity is extremely important. This project will also consider the use of the Peltier effect in conjunction with the technique for storing and releasing heat using phase change materials (PCM - Phase Change Material), successfully tested during Operation Maracati II, in 2010.
