Rapid-heating-up external-heating-type heat loading device

The utility model discloses a rapid-heating-up external-heating-type heat loading device. A reflection plate is formed by connecting and closing a plurality of reflection plate units, of which the radial cross sections are in circular arc shape. A plurality of vertical lamp pipes are arranged in a vertical inner cavity of the reflection plate. The plurality of lamp pipes are in one-to-one correspondence with the plurality of reflection plate units. The lamp pipes are arranged in arc groove corresponding areas at the inner sides of the corresponding reflection plate units respectively. The plurality of lamp pipes are uniformly distributed around a virtual horizontal circle and form a space for placing an object to be heated. The reflection plate and all lamp pipes are arranged in a vertical cylinder, the upper and lower ends of which are opened. The two ends of each lamp pipe are electrically connected with two conductive coils through a lamp pipe clamp respectively. The lamp pipe clamps pass through the cylinder. The reflection plate is provided to enable light rays emitted outward by the lamp pipes to be reflected inwards, thereby improving heat utilization rate of the lamp pipes; and meanwhile, radiation heat conduction mode is utilized, so that the heat loading device has a heat loading capability ensuring a high temperature rising rate and high heating temperature, and can meet high temperature rising rate and loading high temperature requirements.
