The present invention provides an active heat radiation type radiator, which comprises casings of an air inlet and an air outlet, a radiated pipe positioned inside the casing, an air blow component arranged inside the casing and positioned at the air outlet, a humidifying unit positioned between the radiated pipe and the air blow component, and a control unit positioned on the casing, connected with the air blow component and the humidifying unit, and used for controlling the operation of the air blow component and the humidifying unit. The operation of the present invention can improve the heat emission rate of a heater because the air blow component actively emits hot wind to air.
