A body cooling device includes a main body, and at least one fan. The main body is provided with an air import part and two guiding parts. The air import part has an air inlet. The two guiding parts extend from the air import part toward a direction away from the air inlet, and the two guiding parts are symmetrically disposed, with an air outlet disposed at the lower edge of each guiding part, respectively. Each air outlet has a plurality of guiding plates, such that each air outlet is partitioned into plural air outlet portions. The at least one fan is rotatable disposed at the air import part, so as to guide an external air flow into the main body, and the external air flow is subsequently guided to be discharged by the two air outlets.本發明提供一種人體降溫裝置,其包含:一本體,其具有一入風部及兩導引部,其中,入風部具有一入風口,該兩導引部係由入風部兩端延伸而出,且其延伸方向係遠離入風口,而該兩導引部係呈對稱設置,並於下緣皆具有一出風口,各出風口皆設有複數個導風板,以將各出風口分隔成複數個出風區;以及至少一風扇,其轉動地設置於該入風部,用以導引一外界氣流由入風口進入本體中,並使外界氣流經由該兩出風口導出。10‧‧‧本體11‧‧‧入風部12‧‧‧導引部12a‧‧‧外側壁12b‧‧‧內側壁13‧‧‧入風口14‧‧‧網罩15‧‧‧出風口16‧‧‧導風板18‧‧‧容置部19‧‧‧喇叭網罩20‧‧‧風扇30‧‧‧揚聲元件40‧‧‧控制器
