[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A semiconductor wafer efficient cooling device comprises a cutting device body 1, a wafer body 2 and a cutting blade 3, wherein the cutting blade 3 is arranged on the cutting device body 1, and the wafer body 2 is arranged below the cutting blade 3, a fan 5 is fixed on one side of the cutting device body 1, and an air outlet 15 is opened on the top surface of the fan 5, a first fixed block 4 is fixed below the side of the cutting device body 1 away from the fan 5, an air duct 7 is fixed on the first fixed block 4, an opening is arranged at one end of the air duct 7 close to the cutting blade 3, a first transmission pipe 6 is arranged at one end of the air duct 7 away from the cutting blade 3, the first transmission pipe 6 is fixed inside the cutting device body 1, one end of the first transmission pipe 6 is fixedly connected to the air duct 7, and the other end of the first transmission pipe 6 is fixedly connected to the air outlet 15, so that the air duct 7 dissipates heat to the wafer body 2 and the cutting blade 3.

[0023] Specifically, the opening on the air duct 7 is aligned with the contact end of the cutting blade 3 and the wafer body 2 , and the bottom end of the air duct 7 is located above the bottom end of the cutting blade 3 to prevent the air duct 7 from blocking the cutting blade 3 .

[0024] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a second fixed block 8 is fixed on a side of the cutting device body 1 away from the first fixed block 4, a dust box 9 is fixed on an end of the second fixed block 8 close to the cutting blade 3, a dust suction port is opened on the side of the dust box 9 close to the cutting blade 3, a second transmission tube 10 is arranged on the top surface of the dust box 9, the second transmission tube 10 is fixed to one side of the cutting device body 1, one end of the second transmission tube 10 is fixedly connected to the dust box 9, the other end of the second transmission tube 10 is fixedly connected to a recovery box 11, and the top surface of the recovery box 11 is fixedly connected to the fan 5, so that the recovery box 11 recovers the debris of the cutting blade 3 cutting the chip body 2.

[0025] Specifically, the bottom end of the dust box 9 is provided with an inclined surface facing the cutting blade 3, and the bottom end of the dust box 9 is located above the bottom end of the cutting blade 3 to prevent the dust box 9 from blocking the cutting blade 3.
