We study the kinematic and thermal vorticities in low-energy heavy-ion collisions by using ultrarelativistic quantum molecular dynamics model. explore their time evolution spatial distribution. find that initial have a nonmonotonic dependence on collision energy $\sqrt{{s}_{\mathrm{NN}}}$: as $\sqrt{{s}_{\mathrm{NN}}}$ grows first increase steeply then decrease with turning point around $\sqrt{{s}_{\mathrm{NN}}}\ensuremath{\approx}3--5$ GeV depending centrality.
