sufficient cooling liquid 503 is filled in the heat insulation interlayer 501 and the heat insulation bottom layer 502, the controller 3 is used for controlling the semiconductor refrigerating sheet 403 to be opened, so that the cold end of the semiconductor refrigerating sheet 403 exchanges heat with the cooling liquid 503 in the heat insulation interlayer 501, the cooling liquid 503 in the heat insulation interlayer 501 and the cooling liquid 503 in the heat insulation bottom layer 502 can flow mutually, and meanwhile, the cooling of the cooling liquid 503 in the heat insulation bottom layer 502 is realized; the centrifugal tube of the fat sample to be centrifugally processed is placed on a centrifuge tube shelf 6021, the lower end of the rotating shaft 6022 descends to the lowest position under the action of gravity, the key groove 6023 is separated from the inner key part 6032, the water pump 504 is started at the moment, the cooling liquid 503 in the heat-insulating bottom layer 502 is pumped into the centrifugal environment through the water pump 504, the page of the cooling liquid 503 rises to be in contact with the centrifugal tube of the fat cell sample, so that the fat sample can be directly and rapidly cooled through the cooling liquid 503, meanwhile, the upper layer in the heat-insulating interlayer 501 is in a vacuum state, the semiconductor refrigerating sheet 403 can be closed at the moment, and the vacuum state can play a heat-insulating role and reduce heat exchange with the outside. During the cooling process of the fat cell sample, the reflux electromagnetic valve 505 can be opened under the control of the controller 3 to cooperate with the water pump 504, so as to reflux and cool the cooling liquid 503. When the upper cover 2 is closed, the magnet 6041 generates an attracting force to the metal attracting member 6042 upward, the rotation shaft 6022 drives the key groove 6023 to ascend to be matched with the inner key part 6032, the centrifugal motor 601 is started, and the centrifugal operation is started.

By arranging the cooling device 4 and the heat preservation device 5, the cooling liquid 503 in the heat preservation device 5 can be cooled and maintained at a lower temperature through the semiconductor refrigeration sheet 403, so that the heat generation influence of the centrifugal motor 601 in the centrifugal process is reduced, and meanwhile, the cooling liquid 503 in the heat preservation interlayer 501 and the heat preservation bottom layer 502 can be lifted into a centrifugal working space through the water pump 504, so that a sample on the centrifugal tube rack 6021 can be immersed into the cooling liquid 503, the heat transfer efficiency of the cooling liquid 503 and a fat sample can be accelerated, and the survival rate of the fat sample is improved; meanwhile, after the cooling liquid 503 is pumped to the centrifugal working space by the water pump 504, the heat-insulating interlayer 501 is in a vacuum state, so that the heat-insulating effect in the centrifugal working process is further improved. The invention has the advantages of ingenious structural design, good refrigeration and heat preservation effects, stable operation and improvement of the survival rate of fat cells.
