The invention discloses a radiation drying device based on a drying target absorption spectrum and a design method thereof. The device comprises a radiation source, a box body and a power supply, the radiation source is used for generating radiation, the box body comprises a back plate, side plates and a support, and the side plates are provided with air guide holes; the support is used for fixing the radiation source. The power supply is used for supplying power to the radiation sources and controlling on-off of the single radiation source. The design method comprises the following steps: selecting a proper radiation source according to an absorption spectrum of a drying target; calculating the required radiation source power and quantity according to the required radiation power density, the required radiation area and the reflectivity of the existing reflecting plate; designing a box body according to the radiation area and the side length of the radiation target surface; a radiation source arrangement mode is designed, and the radiation intensity is changed by controlling on-off of radiation sources through a power supply. According to the invention, accurate drying of a drying target and radiation distribution with the uniformity greater than 90% and the radiation power density greater than 20W / cm < 2 > under a large-size target can be realized, the energy consumption is reduced, and the drying efficiency is improved.

This invention discloses a radiation drying device based on the absorption spectrum of a drying target. The device includes a radiation source, a housing, and a power supply. The radiation source generates radiation. The housing includes a back plate, side plates, and a support; the side plates have air vents. The support secures the radiation source. The power supply powers the radiation source and controls the switching of individual radiation sources. The design method involves: selecting a suitable radiation source based on the absorption spectrum of the drying target; calculating the required radiation source power and quantity based on the required radiation power density, radiation area, and reflectivity of existing reflectors; designing the housing based on the radiation area and the side length of the radiation target surface; designing the radiation source arrangement; and controlling the switching of the radiation sources via the power supply to change the radiation intensity. This invention enables precise drying of targets and achieves a uniformity greater than 90% and a radiation power density greater than 20 W / cm² for large targets. 2 The radiation distribution is improved, energy consumption is reduced, and drying efficiency is increased.
