  • Infant warmer radiant heater head
    Patent number: 5841944
    Abstract: An infrared radiant heater for use in an infant warmer open care bed. The heater includes a curved reflector within a similarly shaped housing. Between the reflector and casing is at least one baffle made of a heat insulating material. The baffle divides the inside of the housing into a number of separate insulating air gaps. In order to ensure that heat is not conducted through the head, spacers protrude from the housing to support the baffles at their required positions maintaining heat insulating air gaps between the heater head components.
