The invention discloses a crucible assembly and a single crystal growth device with the crucible assembly. The crucible assembly comprises a crucible, a crucible body and a single crystal growth device, the flow guide device divides an inner cavity of the crucible into a first cavity and a second cavity, the first cavity is suitable for containing seed crystals, an air outlet is formed in the cavity wall of the first cavity, the second cavity is suitable for containing raw materials, an air inlet is formed in the cavity wall of the second cavity, and a flow guide channel is limited on the inner side of the flow guide device; the flow guide channel and the seed crystal are oppositely and coaxially arranged in the vertical direction, the flow guide channel comprises a first channel, a second channel and a third channel which are sequentially connected from bottom to top, the side, away from the second channel, of the first channel communicates with the second cavity, and the end, away from the second channel, o
