Infant incubator heating system

The invention relates to the technical field of infant incubators and particularly discloses an infant incubator heating system which comprises a heating chamber (10) formed in one side of the incubator and an air duct structure located between a bed base (20) and a bed tray (6) of the incubator. An air return assembly (11) is arranged between the heating chamber (10) and an inner compartment of the incubator; a heater (8) is arranged in the heating chamber (10), a wind wheel (31) is arranged at the lower portion of the heater (8), and the air exhaust side of the wind wheel (31) is communicated with the air duct structure. According to the infant incubator heating system, the vibration interference of the heating system to an infant bed can be reduced to a certain extent, the heat dissipation area of the air duct structure is large, the uniform diffusion of warm air is facilitated, accordingly the uniform temperature in the incubator is guaranteed, and the softer heat can be transferred to the bed tray. 本发明涉及
