[0024] When using, Figure 3 and Figure 5 As shown, the first probe connector 11 and the second probe connector 12 are connected to the hose 24 on the probe 25 to form a closed cooling water circuit for the probe 25, and then water is injected into the water storage cup 5, and the first peristaltic pump 2, the second peristaltic pump 3 and the negative pressure vacuum pump 9 are started. Through the pumping of the first peristaltic pump 2 and the second peristaltic pump 3, the entire cooling water circuit of the probe 25 is filled with water, and all the air in the water circuit is discharged; the water in the water storage cup 5 flows to the degassing filter 8 under the pumping of the second peristaltic pump 3, and the negative pressure vacuum pump 9 forms a low-pressure area in the air path chamber of the degassing filter 8, forcing the oxygen in the water to penetrate through the water vapor isolation hair of the degassing filter 8. The capillary enters the degassing gas path, and then is discharged outwardly through the negative pressure vacuum pump 9; the water degassed by the degassing filter 8 flows to the transducer of the probe 25 under the pumping of the second peristaltic pump 3, and the transducer is cooled down by heat exchange, and at the same time, the water in the heat dissipation water tank 4 flows to the input end of the filter cylinder 7 under the pumping of the first peristaltic pump 2, and intersects with the water that has cooled the transducer, cools the water that has cooled the transducer, and then after being filtered by the filter cylinder 7, a part of the water flows to the water storage cup 5, continues to be degassed and filtered by the degassing filter 8 to cool the transducer, and the other part of the water flows to the heat dissipation water tank 4 to be cooled by the heat dissipation water tank 4.
[0025] Among them, the degassing filter 8 plays the role of degassing and filtering, and has a degassing membrane and a reverse osmosis membrane.

[0027] When in use, the refrigeration plate 10 is energized to conduct the heat of the water in the heat dissipation water tank 4 to the copper base 14, and dissipate the heat through the heat dissipation ribs 15. At the same time, by tilting the heat dissipation ribs 15 toward the center of the copper base 14, the external cold air can enter the heat dissipation channel between two adjacent heat dissipation ribs 15 along the tilted heat dissipation ribs 15, and dissipate the heat by air convection, thereby realizing heat dissipation by both conduction and air convection.

The vacuum negative pressure gauge 19 is provided to quickly and directly feedback the vacuum degree of the water circuit and monitor the degassing process of the water circuit. When the vacuum degree value of the vacuum negative pressure gauge 19 (between -22inHg and -30inHg) is less than the set value (-22inHg), it means that the water in the water circuit has been degassed (the oxygen content of the water is ≤3ppm), and the requirements for emitting HIFU (high-intensity focused ultrasound) are met.
