We calculate the spectroscopic parameters of resonance X(4630) observed in the process B+→ J/ΨϕK+ by at the LHCb experiments at CERN by means of thermal QCD sum rule method at non-zero temperature. The exotic vector X(4630) is assigned as the diquark-antidiquark state [cs][cs] with spin-parity JPC=1-+. Employing the two-point QCD sum rule approach up to the sixth order of the operator dimension by including non-perturbative contribution, we calculate the mass and decay constant of X(4630) at T≠0. The numerical analyses demonstrate that the values of the mass and decay constant of X(4630) near the deconfinement temperature decrease up to 9.8% and 60% of their vacuum values. At T→0, the obtained results for the mass mX(4630)=(4649±40) MeV and decay constant λX(4630)=(10.07±0.8)×10-3 MeV are in excellent agreement with the results reported by LHCb experiments and other theoretical predictions.
