The invention discloses a novel radiating constant temperature and humidity incubator. The novel radiating constant temperature and humidity incubator comprises a water tank, a handle, a switch, a support, a motor box, an incubator main body, an exhaust fan, a motor, a base and a cabinet door; the base is mounted below the motor box, the cabinet door is mounted on the incubator main body, the handle is mounted on the cabinet door, the switch is mounted above the cabinet door, the support is mounted on the left side of the incubator main body, the water tank is mounted on the support, and the exhaust fan is mounted on the motor box. The novel radiating constant temperature and humidity incubator has the advantages of being rational in design and simple in structure. An insulation rubber layer is arranged on the handle, so that the probability of electric shock is greatly reduced, and the safety is improved. The design of the exhaust fan is added, so that heat in the motor box is dissipated in time, and the safety of the motor is guaranteed.
