[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] The present invention provides a high-frequency resonant cavity arranged in a cooling water channel. The high-frequency resonant cavity is implemented as follows: Figure 1 and Figure 2 As shown, it includes an accelerating chamber 10, a liquid inlet pipe 21 and a liquid outlet pipe 22. The tube wall of the accelerating chamber 10 is hollow to form a cooling channel 11. The liquid inlet pipe 21 and the liquid outlet pipe 22 are both connected to the cooling channel 11, so that the liquid inlet pipe 21 is connected to the liquid outlet pipe 22 through the cooling channel 11.

[0028] During application, the coolant can be input through the liquid inlet pipe 21, and the coolant will flow in the cooling channel 11 to absorb the heat inside the acceleration cavity 10. The heated coolant only needs to flow out through the liquid outlet pipe 22 to take away the heat from the inside of the acceleration cavity 10, thereby achieving efficient heat dissipation. Among them, since the cooling channel 11 is directly arranged in the tube wall of the acceleration cavity 10, not only the device structure is more compact, but also the cooling channel 11 is used to directly absorb heat, which reduces the loss of heat transfer and improves the heat absorption efficiency of the cooling channel 11 to meet more stringent heat dissipation requirements.

[0029] like Figure 1 As shown, the inner wall of the accelerating cavity 10 is provided with a first concave-convex surface 31, and the first concave-convex surface 31 is exposed inside the accelerating cavity 10. After the first concave-convex surface 31 is added, the contact area of ​​the inner wall of the accelerating cavity 10 will be greatly increased, thereby accelerating the absorption of heat by the inner wall of the accelerating cavity 10, thereby improving the heat dissipation efficiency; of course, the first concave-convex surface 31 can be set to a regular concave-convex shape, and can also be set to an irregular concave-convex shape, which can be selected according to actual production needs.

[0030] like Figure 1 As shown, the inner surface of the cooling channel 11 is provided with a second concave-convex surface 32, and the setting position of the second concave-convex surface 32 matches the setting position of the first concave-convex surface 31. For example, the first concave-convex surface 31 and the second concave-convex surface 32 in the figure are arranged adjacent to each other, which can improve the efficiency of heat transfer; and after adding the second concave-convex surface 32, the contact area of ​​the inner surface of the cooling channel 11 will be greatly increased, thereby accelerating the absorption of heat from the cooling channel 11 by the coolant, thereby further improving the heat dissipation efficiency; similarly, the second concave-convex surface 32 can also be set to a regular concave-convex shape or an irregular concave-convex shape, which can also be selected according to actual production needs.

[0031] like Figure 1 As shown, the high-frequency resonant cavity also includes a shielding tube 40, which surrounds the outside of the accelerating cavity 10. After the shielding tube 40 is added, it can block the leakage of neutrons, thereby improving the safety during the application process; wherein, the shielding tube 40 is preferably made of neutron shielding material, among which the best moderating ability is hydrogen-containing material, such as water, paraffin, etc.

[0032] like Figure 1 As shown, the liquid inlet pipe 21 and the liquid outlet pipe 22 pass through the wall of the shielding pipe 40 and extend to the outside of the shielding pipe 40. At this time, the shielding pipe 40 can realize the installation and fixation of the liquid inlet pipe 21 and the liquid outlet pipe 22, and can also realize the anti-leakage protection of the coolant at the inlet and outlet positions.

[0033] like Figure 1 As shown, both ends of the accelerating chamber 10 are provided with fixing plates 50, and both ends of the shielding tube 40 are respectively arranged on the two fixing plates 50, so that both ends of the shielding tube 40 can be installed and fixed on the fixing plates 50, and the installation and fixation of the accelerating chamber 10 and other components are also realized.

[0034] like Figure 1 As shown, the inner walls of both ends of the shielding tube 40 are provided with fixing frames 41, and the fixing frames 41 are connected and fixed to the fixing plate 50. At this time, the fixing plate 50 will cover the shielding tube 40 from the outside, and the fixing frames 41 realize the connection and fixation between the inside of the shielding tube 40 and the fixing plate 50, thereby making the connection and fixation between the shielding tube 40 and the fixing plate 50 more stable.

[0035] like Figure 1 and Figure 2 As shown, a flow balancing plate 60 is provided in the cooling channel 11, and a plurality of through holes 61 are provided on the flow balancing plate 60. The flow balancing plate 60 is annular and arranged around the inner cavity circumference of the acceleration cavity 10 to separate the cooling channel 11 into two parts.

[0036] For example, in this embodiment, the cross section of the accelerating chamber 10 is annular, that is, the cross section of the cooling channel 11 is also annular, so the annular flow plate 60 can block the cooling channel 11 into two parts. Figure 1 In the direction shown, the flow equalizing plate 60 divides the cooling channel 11 into two parts, the left and the right. At this time, the coolant only needs to flow through the flow equalizing plate 60 to achieve flow equalization, thereby improving the smoothness of the coolant flow.

[0037] In this embodiment, the liquid inlet pipe 21 and the liquid outlet pipe 22 are connected to the cooling channel 11 on both sides of the flow equalizer 60, and the liquid inlet pipe 21 and the liquid outlet pipe 22 are respectively placed on opposite sides of the acceleration chamber 10; Figure 1 In the direction shown, the coolant needs to flow from the upper right side to the lower left side, thereby achieving the lateral and vertical flow of the coolant and ensuring the comprehensive heat absorption of the accelerating cavity 10 by the coolant.

[0038] In addition, the flow equalizing plate 60 is arranged adjacent to the liquid inlet pipe 21, which can ensure that the flow equalizing treatment is performed immediately after the coolant enters the cooling channel 11, thereby providing better protection for the flow stability of the entire flow process of the coolant.

[0039] The above are preferred embodiments of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
