Abstract


The Grashof incubator uses natural convection where the transfer of heat from a bulb lamplight as a heating element to the baby chamber is not generated by an external source like a blower, fan or suction device but only by density differences occuring due to temperature gradients. The density of air depend on its temperature, if the temperature rise the density decreased that means the air become lighter then move upward. Heating chamber connect to the outside air by several holes allowing fresh-air enter the heating chamber replace the hot air which moving upward to the baby’s cabin. The mission of the community services in this applied technology is to help the preemies baby who’s suffer a hypothermia because of the prematurity which means that the baby was born before 37 weeks of the pregnancy. Especially, these social-entrepreneurship action destinate to cover the poor people who cannot afford financially the hospital administration fees which is so far too expensive. After 4 years rolling such an implementation of our thermal knowledge, more than thousand babies over 14 provinces in the country have already been saved.
