Cosmic-ray (CR) anti-nuclei are often considered as important observables fordark matter (DM) indirect detections at low kinetic energies below GeV pernucleon. Since the primary CR fluxes drop quickly towards high energies, thesecondary anti-nuclei in CR are expected to be significantly suppressed in highenergy regions ($\gtrsim 100$ GeV per nucleon). If DM particles are heavy, theannihilation productions of DM can be highly boosted, thus the fluxes ofanti-nuclei produced by DM annihilations may exceed the secondary background athigh energies, which opens a high energy window for DM indirect detections. Weinvestigate the possibility of detecting heavy DM particles which annihilateinto high energy anti-nuclei. We use Monte-Carlo generators $\texttt{PYTHIA}$,$\texttt{EPOS-LHC}$ and $\texttt{DPMJET}$ and the coalescence model to simulatethe production of anti-nuclei, and constrain the DM annihilation cross sectionsby using the AMS-02 and HAWC antiproton data and the HESS galactic centergamma-ray data. We find that the conclusion depends on the choice of DM densityprofiles. For the "Cored" type profile with a DM particle mass $\gtrsim 10$TeV, the contributions from DM annihilations can exceed the secondarybackground in high energy regions, which opens the high energy window. Whilefor the "Cuspy" type profile, the excess disappears.
