[0048] The liquid extraction pump 2 extracts the coolant inside the liquid storage tank 1 and sends it into the cooling pipe 3. The coolant cools and dissipates heat from the component to be cooled. After absorbing heat, the coolant enters the inside of the ring frame 4. The driving member 7 drives the driving rod 8 to rotate, and the driving rod 8 drives the first heat dissipation mechanism to rotate.

The partition and sprinkling component separates and sprinkles the coolant. At the same time, the partition and sprinkling component drives the first rotating rod 13 to revolve, and the first rotating rod 13 drives the gear 9 to revolve.

[0067] An elastic member 19, one end of which is connected to the sliding rod 18 and the other end of which is connected to the fixing rod 17.

[0068] The driving rod 8 drives the transmission component 15 to rotate, the transmission component 15 drives the second rotating rod 16 to rotate, the second rotating rod 16 drives the second fan blade 20 to rotate, accelerating the air flow rate, thereby dissipating heat from the coolant.
