Description

Technical Field

[0001] This utility model relates to the field of ultrasonic transducer technology, and in particular to an ultrasonic transducer with a protective structure. Background Technology

[0002] An ultrasonic transducer is an energy conversion device that can convert alternating electrical signals within the ultrasonic frequency range into acoustic signals, or vice versa. An ultrasonic transducer mainly consists of a piezoelectric ceramic disc transducer, a shell, and other structures. The piezoelectric ceramic is the core component of the transducer, which realizes the conversion between electrical energy and mechanical energy through the piezoelectric effect. When an alternating voltage is applied to the piezoelectric ceramic, it will generate mechanical vibration, thereby generating ultrasonic waves.

[0003] In existing transducers, to ensure effective heat dissipation, the piezoelectric ceramic rings and other structures are directly exposed. Therefore, they are susceptible to mechanical damage from contact with external objects, reducing their service life. Furthermore, in some operating environments, the transducers may come into direct contact with corrosive materials, further shortening their lifespan. While installing protective covers or other protective structures can protect the transducers from external damage, it can also obstruct airflow, preventing heat from dissipating in a timely manner. This can lead to an increase in transducer temperature, affecting its operating efficiency and stability. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic transducer with a protective structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An ultrasonic transducer with a protective structure includes a lower driver, a first fixed flange fixedly mounted on the outside of the lower driver, an upper driver fixedly mounted on the upper end of the lower driver, a plurality of piezoelectric ceramic rings fixedly mounted between the lower driver and the upper driver, a welding head fixedly mounted on the lower end of the lower driver, a protective cover fixedly mounted on the lower driver, the piezoelectric ceramic rings, and the outside of the upper driver, a plurality of heat dissipation fins fixedly mounted inside the protective cover, and a plurality of heat-conducting pipes fixedly mounted between the plurality of heat dissipation fins.

[0007] As a further preferred embodiment of this utility model, a heat-conducting cover is also provided on the inner side of the protective cover, and the outer side of the heat-conducting cover is fixedly connected to one side of multiple heat dissipation fins.

[0008] As a further preferred embodiment of this utility model, a second fixing flange is fixedly installed at the lower end of the protective cover. The second fixing flange is fixedly installed on the first fixing flange, and the heat-conducting cover is interlaced and installed on the outside of the lower driver, the piezoelectric ceramic ring, and the upper driver. Thermal grease is applied between the heat-conducting cover and the lower driver, the piezoelectric ceramic ring, and the upper driver. By interlacing the protective cover and the heat-conducting cover on the outside of the lower driver, the piezoelectric ceramic ring, and the upper driver, the inner side of the heat-conducting cover can be in contact with the outer side of the lower driver, the piezoelectric ceramic ring, and the upper driver, thereby cooperating with the heat dissipation fins to dissipate the heat generated by the lower driver, the piezoelectric ceramic ring, and the upper driver during operation.

[0009] As a further preferred embodiment of this utility model, the side of the heat dissipation fin away from the heat conduction cover extends through the protective cover to the outside of the protective cover and has multiple pipe holes. The multiple pipe holes in the heat dissipation fin can provide basic conditions for the installation of the heat conduction pipe.

[0010] As a further preferred embodiment of this utility model, the heat-conducting pipe is installed in the tube holes of multiple heat dissipation fins, and an air inlet pipe is fixedly installed at one end of the heat-conducting pipe. The air inlet pipe is connected to the output end of an external fan or air compressor through a pipeline.

[0011] As a further preferred embodiment of this utility model, multiple air nozzles are fixedly installed on the outside of the heat pipe, and the air nozzles are obliquely positioned in the direction of the corresponding heat dissipation fins. Through the arrangement of the heat pipe, air can be delivered into the heat pipe and discharged in conjunction with an external fan or air compressor, which can improve the heat dissipation effect of the heat dissipation fins. Furthermore, the heat dissipation effect can be further improved by blowing air onto the outer surface of the heat dissipation fins with the help of multiple air nozzles.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a protective cover is provided on the outside of the lower driver, and a heat-conducting cover is provided on the inside of the protective cover and fitted onto the outside of the lower driver, the piezoelectric ceramic ring, and the upper driver. This, together with the heat dissipation fins, can protect the lower driver, the piezoelectric ceramic ring, and the upper driver, and achieve heat dissipation. In addition, heat-conducting pipes are provided between multiple heat dissipation fins, and multiple angled air nozzles are provided on the outside of the heat-conducting pipes. This can be used with external air delivery equipment to achieve rapid heat dissipation of the heat dissipation fins, thereby improving the overall heat dissipation effect of the structure.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, the present invention provides an ultrasonic transducer with a protective structure, including a lower driver 1, a first fixed flange 2 fixedly installed on the outside of the lower driver 1, an upper driver 4 fixedly installed on the upper end of the lower driver 1, a plurality of piezoelectric ceramic rings 3 fixedly installed between the lower driver 1 and the upper driver 4, a welding head 5 fixedly installed on the lower end of the lower driver 1, a protective cover 6 fixedly installed on the outside of the lower driver 1, the piezoelectric ceramic rings 3, and the upper driver 4, a plurality of heat dissipation fins 7 fixedly installed inside the protective cover 6, and a plurality of heat conduction pipes 8 fixedly installed between the plurality of heat dissipation fins 7.

[0021] A heat-conducting cover 10 is also provided inside the protective cover 6, and the outer side of the heat-conducting cover 10 is fixedly connected to one side of multiple heat dissipation fins 7. A second fixing flange 9 is fixedly installed at the lower end of the protective cover 6. The second fixing flange 9 is fixedly installed on the first fixing flange 2, and the heat-conducting cover 10 is inserted and installed on the outer side of the lower driver 1, the piezoelectric ceramic ring 3, and the upper driver 4. Thermal grease is applied between the heat-conducting cover 10 and the lower driver 1, the piezoelectric ceramic ring 3, and the upper driver 4. By inserting the protective cover 6 and the heat-conducting cover 10 on the outer side of the lower driver 1, the piezoelectric ceramic ring 3, and the upper driver 4, the inner side of the heat-conducting cover 10 can be in close contact with the outer side of the lower driver 1, the piezoelectric ceramic ring 3, and the upper driver 4, thereby cooperating with the heat dissipation fins 7 to dissipate the heat generated by the lower driver 1, the piezoelectric ceramic ring 3, and the upper driver 4 during operation. The side of the heat sink 7 away from the heat conduction cover 10 extends through the protective cover 6 to the outside of the protective cover 6 and has multiple pipe holes 11. Multiple pipe holes 11 are opened in the heat sink 7 to provide basic conditions for the installation of the heat conduction pipe 8. The heat conduction pipe 8 is coiled in the pipe holes 11 of the multiple heat sink fins 7, and one end of the heat conduction pipe 8 is fixedly installed with an air inlet pipe 13. The air inlet pipe 13 is connected to the output end of an external fan or air compressor through a pipe. Multiple air nozzles 12 are fixedly installed on the outside of the heat conduction pipe 8, and the air nozzles 12 are obliquely placed in the direction of the corresponding heat sink fin 7. Through the setting of the heat conduction pipe 8, air can be delivered into the heat conduction pipe 8 and discharged in conjunction with the external fan or air compressor, which can improve the heat dissipation effect of the heat sink fin 7. In addition, the multiple air nozzles 12 can blow on the outer surface of the heat sink fin 7 to further improve the heat dissipation effect.

[0022] It should be noted that this utility model is an ultrasonic transducer with a protective structure. When installing the protective cover 6, the protective cover 6 can be inserted from the lower port through the upper driver 4, so that the heat-conducting cover 10 can be inserted through the lower driver 1, the piezoelectric ceramic ring 3, and the outer side of the upper driver 4. Before this, thermal grease needs to be applied to the inner side of the heat-conducting cover 10 to improve the heat conduction efficiency. Then, the lower end of the second fixing flange 9 is attached to the first fixing flange 2, and the second fixing flange 9 and the first fixing flange 2 are fixed with bolts. Then, one end of the external hose is connected to One end of the hose is connected to the intake pipe 13, and the other end is connected to the output end of the fan or air compressor. This allows cold air to be delivered into the heat pipe 8, so that the heat conduction cover 10 can conduct heat into multiple heat dissipation fins 7 and dissipate heat through the heat dissipation fins 7. At the same time, the heat dissipated by the heat dissipation fins 7 is also transferred to the heat pipe 8, and the high-speed airflow in the heat pipe 8 can carry away some of the heat. Meanwhile, multiple angled air nozzles 12 on the outside of the heat pipe 8 blow towards the heat dissipation fins 7, which can accelerate the airflow near the heat dissipation fins 7, thereby further improving the heat dissipation efficiency of the heat dissipation fins 7.
