[0002] A microwave waveguide is a transmission line used to transmit microwave signals, and it is widely used in fields such as communications, radar, satellite ground stations, and microwave measurement. With the development of microwave technology, the application of high-power microwave equipment is becoming more and more widespread, and the performance requirements for microwave waveguides are also becoming more and more stringent.

[0003] In microwave waveguides, soft waveguides are widely used in microwave systems due to their flexibility, allowing them to be stretched and compressed to a certain extent along the axial direction and bent at certain angles. Soft waveguides typically consist of a waveguide with a bellows structure, with both ends of the waveguide sealed to a rigid waveguide via flanges.

[0004] However, while existing flexible waveguides possess a certain degree of flexibility, heat dissipation remains a significant challenge during high-power microwave transmission. Therefore, a technical solution is urgently needed that can effectively address the heat dissipation problem of high-power microwave waveguides while maintaining their flexibility.

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please see Figures 1-2 This utility model provides a water-cooled high-power microwave waveguide, including a microwave waveguide 100 and a water-cooling heat dissipation system 200.

[0026] Please refer to Figure 3 The Microsoft waveguide 100 is fixed to flanges 130 at both ends via transition pieces 120. The Microsoft waveguide 100 has a corrugated structure along its axial direction, creating multiple parallel annular grooves 110. The cross-sectional shape of the corrugated structure is a near-sine curve, and the annular grooves 110 are equidistantly distributed. The Microsoft waveguide 100 is made of a flexible material, which allows it to maintain good electrical performance while possessing a certain degree of elastic deformation capability, facilitating installation and adapting to different operating environments.

[0027] Please refer to Figures 4-5 The water-cooled heat dissipation system 200 includes two heat dissipation pipe assemblies 210 respectively disposed on the upper and lower sides of the Microsoft waveguide 100, and the two heat dissipation pipe assemblies 210 are connected by a connecting pipe 220. Each heat dissipation pipe assembly 210 includes a first cooling pipe 211 and a second cooling pipe 212 respectively disposed on both sides of the Microsoft waveguide 100. Multiple third cooling pipes 213 are arranged at intervals between the first cooling pipe 211 and the second cooling pipe 212, and the two ends of the third cooling pipes 213 are connected to the first cooling pipe 211 and the second cooling pipe 212 respectively. The third cooling pipes 213 in the heat dissipation pipe assembly 210 on the same side are parallel to each other, and the third cooling pipes 213 are correspondingly installed in the annular groove 110. The outer diameter of the third cooling pipe 213 is smaller than the opening diameter of the annular groove 110; and the outer diameter of the third cooling pipe 213 is smaller than the outer diameter of the first cooling pipe 211 / second cooling pipe 212. One of the first cooling pipes 211 is connected to the water inlet pipe 230, and the other first cooling pipe 211 is connected to the water outlet pipe 240. The connecting pipe 220 is a U-shaped bend, and its two ends are connected to the upper and lower second cooling pipes 212 respectively. All the pipes of the water cooling system 200 are made of copper pipes. Copper pipes have excellent thermal conductivity and can quickly conduct away the heat generated by the Microsoft waveguide 100, ensuring the normal operating temperature of the Microsoft waveguide 100.

[0028] Please refer to Figures 1-2 and Figure 6 The water-cooled high-power microwave waveguide also includes a fixing component 300 for tightly fitting the third cooling tubes 213 on both sides of the waveguide 100 into the annular groove 110. The fixing component 300 includes a fixing seat 310, a movable pin 320, a pressure plate 330, and a nut 340. The fixing seat 310 is "U"-shaped, and through holes for the third cooling tubes 213 to pass through are respectively opened at both ends of the fixing seat 310. One end of the movable pin 320 is rotatably installed in the middle of the fixing seat 310, and the other end of the movable pin 320 is provided with a nut 340 that is threadedly connected to it. The pressure plate 330 is slidably mounted on the movable pin 320.

[0029] In practical applications, the working principle of this water-cooled high-power microwave waveguide is as follows: As a microwave transmission channel, the Microsoft waveguide generates a significant amount of heat when high-power microwaves are transmitted within it. To effectively dissipate this heat, a water-cooling system introduces cooling water into the first cooling pipe via an inlet pipe. The cooling water then flows through multiple third cooling pipes. Because these third cooling pipes are installed close to the annular grooves within the Microsoft waveguide, they directly absorb the heat generated by the waveguide. After absorbing heat, the cooling water flows into the second cooling pipe, and then through a connecting pipe into the heat dissipation pipe assembly on the other side for further heat dissipation of the Microsoft waveguide, finally exiting through the outlet pipe.

[0030] In summary, the corrugated structure of this microwaveguide not only increases the stability of microwave transmission but also expands the heat dissipation area. Multiple third cooling pipes are tightly fitted within the annular groove, allowing cooling water to be closer to the heat source and improving heat dissipation efficiency. The design of the fixing components ensures that the third cooling pipes are tightly fitted within the annular groove, further improving heat conduction efficiency. The heat dissipation pipe assemblies on the upper and lower sides form a complete water circulation path through connecting pipes, allowing cooling water to fully contact all parts of the microwaveguide for all-around heat dissipation. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
