Axial-flow type air duct structure of warmer

Abstract

The utility model discloses a warmer axial-flow type air duct structure which comprises a warmer shell, an air hole unit is arranged on the outer side of one end of the warmer shell, supports are fixed to the positions, located on the two sides of the air hole unit, in the warmer shell, one end of each support is provided with a direct-current fan used for generating ventilation airflow, and the other end of each support is provided with a direct-current fan used for generating ventilation airflow. Wherein one support is communicated with a PTC mold frame with a built-in PTC heating module, the PTC mold frame is internally provided with a flow dividing assembly used for guiding ventilation airflow to evenly penetrate through the PTC heating module, the ventilation airflow is pressurized on one side of the flow uniformizing plate and then passes through all the flow uniformizing holes, and even airflow can be formed; uniform airflow is guided by all the flow guide plates and then turns to pass through the PTC heating module, the heating efficiency and hot air uniformity are improved, the oblique flow plate can effectively reduce wind resistance and wind noise, and the sound insulation cover on the outer side of the support is made of porous sound absorption cotton materials, so that noise generated when the direct-current draught fan operates is lowered.
