Claim 4:
5. The two-phase flow active and passive multi-level data center cabinet cooling device according to claim 4, wherein
the first CPU (26-1) of the blade server, the second CPU (26-2) of the blade server and a thermal interface material (29) are integrated, and a ring structure (32) wrapping a thermosiphon evaporation section pipeline in the thermal interface material (29) wraps the thermosiphon evaporation section pipeline (28);
4 thermosiphon evaporation section pipelines (28) are connected in parallel and connected with the rack-level loop thermosiphon (11);
the thermal interface material (29) has a fractal tree-like flow channel (35), two fluid inlets a thermal interface material cooling medium left inlet (33-1) and a thermal interface material cooling medium right inlet (33-2), and two fluid outlets such as a thermal interface material cooling medium left outlet (34-1) and a thermal interface material cooling medium right outlet (34-2);
the thermal interface material cooling medium left inlet (33-1) and the thermal interface material cooling medium right inlet (33-2) are connected to the pipeline of the rack-level loop thermosiphon (11) on a left side of the thermosiphon evaporation section pipeline (28) via a thermal interface material cooling medium inlet pipeline (30);
the thermal interface material cooling medium left outlet (34-1) and the thermal interface material cooling medium right outlet (34-2) are connected to the pipeline of the rack-level loop thermosiphon (11) on a right side of the thermosiphon evaporation section pipeline (28) via a thermal interface material cooling medium outlet pipeline (31).
