The invention discloses a heat transferring medium and a cooling device provided with the heat transferring medium. The heat transferring medium comprises a hollow sphere and a phase change material filled in the hollow sphere. The cooling device comprises a shell, an electric spindle channel and a heat transferring medium channel, wherein the electric spindle channel and the heat transferring medium channel are arranged in the shell, the heat transferring medium channel is distributed along the periphery of the electric spindle channel and is used for filling the heat transferring medium, the cooling device is further provided with a driving mechanism connected to the heat transferring medium channel and used for driving the heat transferring medium to move, and a cooling mechanism connected to the driving mechanism. According to the heat transferring medium, the phase change material is prevented from leaking from the hollow sphere. According to the cooling device, the heat transferring medium is driven to
