We present a detailed discussion on the doubly charmed baryon 
production at the RHIC and LHC via the proton–nucleus (p–N) and nucleus–nucleus (N–N) collision modes. The extrinsic charm mechanism via the subprocesses 
and 
together with the gluon-gluon fusion mechanism via the subprocess 
have been taken into consideration, where the intermediate diquark is in 
-state or 
-state, respectively. Total and differential cross sections have been discussed under various collision energies. To compare with the production via proton-proton collision mode at the LHC, we observe that sizable events can also be generated via p–N and N–N collision modes at the RHIC and LHC. For examples, about 
and 
events can be accumulated in p-Pb and Pb-Pb collision modes at the LHC within one operation year.
