[0029] As Figures 1-5The utility model provides a technical scheme: a heat dissipation type array ultrasonic transducer, include: the lantern ring 12, the outside of lantern ring 12 is sleeved with heat dissipation ring 2, heat dissipation ring 2 includes semicircle ring one 21 and semicircle ring two 22, the middle part of semicircle ring one 21 one end is equipped with movable slot 26, the middle part of movable slot 26 is fixedly installed with fixed block 27, the upper and lower of movable slot 26 middle part are slidably connected with the insertion rod 29, the one end of two insertion rods 29 is fixedly installed with L type clamping block 30, the one end of two insertion rods 29 and the upper and lower of fixed block 27 are all fixedly connected with telescopic spring rod 28, the one side of semicircle ring one 21 one end middle part is equipped with moving slot 31, the upper and lower of moving slot 31 middle part are slidably connected with the lever 32, the one end of two levers 32 is fixedly connected with the one side of insertion rod 29 respectively, the upper and lower of semicircle ring one 21 other end middle part are fixedly installed with guide rod 25, the upper and lower of semicircle ring two 22 other end middle part are equipped with guide slot 33, the upper and lower of semicircle ring two 22 one end middle part are equipped with inclined surface insertion slot 34, the one end of two inclined surface insertion slots 34 is equipped with clamping slot 35, the front end of inclined surface insertion slot 34 is greater than the rear end, insertion rod 29 and L type clamping block 30 are slidably inserted in the middle part of inclined surface insertion slot 34 respectively, insertion rod 29 is inserted in the middle part of clamping slot 35, the upper and lower of semicircle ring one 21 and semicircle ring two 22 outer surface middle part are evenly equipped with multiple S type air ducts 23, multiple S type air ducts 23 are arrayed, the inlet of multiple S type air ducts 23 is greater than the outlet, the middle part of semicircle ring one 21 and semicircle ring two 22 outer surface is evenly fixedly installed with multiple heat dissipation fins 24, multiple heat dissipation fins 24 are arrayed.
[0030] In this embodiment, a quick-release heat dissipation ring 2 is designed, consisting of a first semicircular ring 21 and a second semicircular ring 22. This design allows the heat dissipation ring 2 to be easily fitted onto the outer side of the collar 12 on the surface of the ultrasonic transducer. Made of copper with good thermal conductivity, during installation, simply align the first semicircular ring 21 and the second semicircular ring 22 with the collar 12 and gently press. The L-shaped locking block 30 at the end of the insertion rod 29 will smoothly engage with the slot 35 under the action of the spring force, thus completing the installation. When disassembly is required, by moving the lever 32, the insertion rod 29 can be pulled out of the slot 35, easily separating the first semicircular ring 21 and the second semicircular ring 22. Multiple S-shaped air channels 23 are evenly distributed on the outer surface of the first semicircular ring 21 and the second semicircular ring 22. When the transducer vibrates, air flows along a curved path within the channels, increasing airflow turbulence and the contact area with the channel wall, thereby improving heat dissipation. Efficiency is enhanced because the air has a longer contact time with the heat dissipation ring 2 when flowing in the S-shaped air passage 23, allowing for more efficient heat absorption. For example, when outside air enters the S-shaped air passage 23, the curved structure causes the air to change direction continuously and come into contact with the air passage wall multiple times, thus improving the efficiency of heat exchange. At the same time, the inlets of multiple S-shaped air passages 23 are larger than the outlets. According to the principles of fluid dynamics, the air velocity increases when flowing in this variable diameter structure. The increased velocity can improve the convective heat transfer coefficient, allowing heat to be transferred from the surface of the heat dissipation ring 2 to the air more quickly, thereby enhancing the heat dissipation effect. In addition, the multiple heat dissipation fins 24 installed on the outer surfaces of the semicircular ring 1 21 and semicircular ring 22 can significantly increase the surface area of the heat dissipation ring 2. A larger heat dissipation surface area means that more heat can be dissipated to the surrounding environment more quickly through heat conduction and heat convection. Example
[0031] like Figures 1-4 As shown, multiple sets of piezoelectric ceramic plates 16 are uniformly fixedly installed in the middle of the collar 12, and an electrode 17 is fixedly installed between the middle of every two sets of piezoelectric ceramic plates 16. A front driver 13 is fixedly installed at the upper end of the collar 12, and an upper fixed plate 14 is fixedly installed at the upper end of the middle of the front driver 13. A lower fixed plate 15 is fixedly installed at the lower part of the middle of the collar 12. A heat dissipation ring 2 is snapped into the space formed between the middle of the upper fixed plate 14 and the lower fixed plate 15. A rear driver 1 is fixedly installed at the lower end of the collar 12, and a warning screw hole 11 is opened in the middle of the lower end of the rear driver 1.
[0032] In this embodiment, the multiple groups of piezoelectric ceramic sheets 16 evenly installed in the middle of the collar 12 and the electrodes 17 fixed between every two groups of piezoelectric ceramic sheets 16 constitute an efficient system of converting electrical energy into mechanical energy. When the electrodes 17 apply an alternating electric field, the piezoelectric ceramic sheets 16 generate periodic expansion and contraction deformation based on the inverse piezoelectric effect, and then efficiently generate ultrasonic waves. The front driver 13 is fixed on the upper end of the collar 12, and the upper end of the front driver 13 is further installed with the upper fixed disc 14, which provides a stable support for the front end of the ultrasonic transducer. The heat dissipation ring 2 is clamped in the space between the middle of the upper fixed disc 14 and the lower fixed disc 15, which realizes the efficient heat dissipation in close contact with the heat source of the ultrasonic transducer, i.e. the piezoelectric ceramic sheets 16 and the electrodes 17. The position enables the heat dissipation ring 2 to quickly absorb the heat generated by the working of the piezoelectric ceramic sheets 16, and then dissipate the heat through the S-shaped air duct 23 and the heat dissipation fins 24, etc. structures, which can effectively reduce the working temperature of the transducer, improve its working efficiency and service life. The early warning screw hole 11 opened in the middle of the lower end of the rear driver 1 provides convenience for installing temperature, pressure and other sensors.
[0033] Working principle:
[0034] As Figures 1-5As shown, the piezoelectric ceramic sheet 16 and the electrode 17 fixed between every two groups of piezoelectric ceramic sheet 16 are evenly installed in the middle of the sleeve ring 12, which constructs an efficient system of converting electrical energy into mechanical energy, when the electrode 17 applies an alternating electric field, the piezoelectric ceramic sheet 16 generates periodic expansion and contraction deformation based on the inverse piezoelectric effect, and then efficiently generates ultrasonic waves, the front driver 13 is fixed on the upper end of the sleeve ring 12, and the upper end of the sleeve ring 12 is provided with a fixed disc 14, which provides stable support for the front end of the ultrasonic transducer, and the detachable heat dissipation ring 2 is composed of a half ring one 21 and a half ring two 22, which can be conveniently sleeved outside the sleeve ring 12 on the surface of the ultrasonic transducer, wherein the heat dissipation ring 2 is made of copper with good thermal conductivity, and during installation, the half ring one 21 and the half ring two 22 are aligned with the sleeve ring 12, and then pressed gently, and the L-shaped clamping block 30 at the end of the insertion rod 29 will be smoothly clamped into the clamping groove 35 under the action of the spring force, so as to complete the installation, and when disassembly is needed, the insertion rod 29 is pulled out of the clamping groove 35 by rotating the lever 32, so that the half ring one 21 and the half ring two 22 can be easily separated, wherein a plurality of S-shaped air passages 23 are evenly arranged on the outer surfaces of the half ring one 21 and the half ring two 22, when the transducer vibrates, air will flow along the curved path in the channel, increasing the disturbance of airflow and the contact area with the channel wall, thereby improving the heat dissipation efficiency, and the inlet of the plurality of S-shaped air passages 23 is larger than the outlet, according to the principle of fluid mechanics, when air flows in such a variable diameter structure, the flow rate will increase, and the increase of the flow rate can improve the convective heat transfer coefficient, so that heat can be transferred from the surface of the heat dissipation ring 2 to the air more quickly, and in cooperation with the plurality of heat dissipation fins 24 installed on the outer surfaces of the half ring one 21 and the half ring two 22, the surface area of the heat dissipation ring 2 can be significantly increased, and the larger heat dissipation surface area means that more heat can be quickly dissipated to the surrounding environment through heat conduction and heat convection, which can further enhance the heat dissipation effect, and the early warning screw hole 11 is arranged in the middle of the lower end of the rear driver 1, which provides convenience for installing temperature, pressure and other sensors.
