Rapid heating internal heating type heat loading device

The utility model discloses a rapid heating internal heating type heat loading device. Two transverse lamp tube integrated boards are fixedly connected via vertical connecting rods. Multiple vertical lamp tubes are installed between the two lamp tube integrated boards and are evenly distributed around a virtual circle. The two wire connecting ends of the two ends of the multiple lamp tubes are respectively connected with the two lamp tube integrated boards. The two lamp tube integrated boards are provided with wire connecting terminals which are used for being externally connected with a power supply. A reflecting board is formed by multiple reflecting board units via mutual connection and enclosing, and the radial cross section of the reflecting board units is arc-shaped. The multiple reflecting board units are corresponding to the multiple lamp tubes in a one-to-one way. The lamp tubes and the reflecting board units are coaxial. The lamp tubes are arranged in the arc-shaped slot areas of the external sides of the corresponding reflecting board units. The reflecting board and all the lamp tubes are arranged in a vertical sleeve. Light rays emitted to the internal side by the lamp tubes are outwardly reflected via arrangement of the reflecting board so that heat utilization rate of the lamp tubes is enhanced. Meanwhile, a radiation heat conduction mode is adopted so that the rapid heating internal heating type heat loading device has heat loading capacity with high temperature rise rate and high heating temperature.
