Description

Technical Field

[0001] This utility model relates to the field of transducer technology, and more specifically to CPU piezoelectric cooling transducers. Background Technology

[0002] CPU piezoelectric cooling transducers are components used for CPU heat dissipation based on the piezoelectric effect. They convert electrical energy into mechanical energy, generating airflow or driving liquid flow to remove heat from the CPU. When an alternating electric field is applied to the piezoelectric ceramic material of the cooling transducer, its crystal structure undergoes periodic deformation, producing micrometer-level displacement or bending. This minute vibration, through specific mechanical structure design, can be converted into effective airflow or liquid flow, thereby achieving CPU cooling. For example, a piezoelectric fan typically consists of a cantilever beam with piezoelectric ceramic sheets attached. Driven by an AC voltage, the periodic deformation of the piezoelectric sheets causes the cantilever beam to oscillate back and forth at its resonant frequency with large amplitude, stirring the surrounding air and generating directional airflow for heat dissipation.

[0003] For example, in the transducer disclosed in the prior art CN219043457U, when the piezoelectric ceramic sheet and the metal sheet are placed inside the bottom shell, the first shell and the second shell are connected by a connecting structure. The bottom shell can secure the piezoelectric ceramic sheet and the metal sheet inside the bottom shell. The lead wire passes through the wire hole to the outside of the bottom shell and is fixed in the wire hole by the fixing component. This can reduce the possibility of the lead wire connection falling off and affecting the normal use of the piezoelectric ceramic transducer, and play a certain protective role for the lead wire connection.

[0004] However, the existing technology described above still has the following problems in use: While traditional cooling transducers can provide some cooling when used with a CPU, their heat dissipation rate is slow, and their cooling effect decreases after long-term use, affecting the CPU's cooling performance. Therefore, this invention provides a CPU piezoelectric cooling transducer with high cooling efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a CPU piezoelectric cooling transducer. By cooperating with the heat sink, the cooling efficiency of the CPU can be significantly improved. Furthermore, the heat sink is fixed by a limiting block and a fixing plate, which facilitates quick installation by the staff and effectively improves installation efficiency. In addition, the fixing plate is fixed by a plug rod, a compression spring, and a slot, which further enhances the convenience of installation and disassembly of the overall structure, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CPU piezoelectric cooling transducer, comprising a transducer body, a heat sink on the top of the transducer body, the heat sink being a device for transferring heat from a heat source to the surrounding environment, limiting blocks fixedly provided on both sides of the transducer body, the heat sink being disposed between the two limiting blocks, a fixing plate hinged to the front end of each of the two limiting blocks, an installation groove opened on the top of each of the two limiting blocks, an installation cylinder fixedly provided inside the installation groove, a rod slidably provided inside the installation cylinder, a slot adapted to the rod opened on the top of each of the two fixing plates, the rod being inserted into the slot, a compression spring connected between the top of the rod and the inner wall of the installation cylinder, the compression spring being compressed when squeezed, and when the rod is no longer limited, the compression spring automatically recovers its deformation and pushes the rod into the slot, thereby maintaining the fixation of the fixing plate.

[0007] In a preferred embodiment, a pull rod is fixedly provided at the top of each of the two insertion rods. The top of the pull rod passes through the mounting cylinder and extends into the mounting groove. The pull rod facilitates the worker to quickly open the fixing plate, thereby improving the speed of radiator disassembly and assembly.

[0008] In a preferred embodiment, connecting plates are fixedly provided on both sides of the radiator, and two symmetrically distributed fixing holes are opened on the top of each connecting plate. Each fixing hole is filled with a fastening bolt, and the radiator and the fixing fastener are fixed by means of threaded connection, thereby improving the stability of the entire cooling structure.

[0009] In a preferred embodiment, the outer walls of multiple fastening bolts are fitted with the same fixing buckle, which cooperates with the heat sink to fix the CPU, thereby improving the stability of the transducer body.

[0010] In a preferred embodiment, wires are fixedly provided on both sides of the front end of the transducer body, and a wire coil is sleeved on the outer wall of each wire. The wire coil is wrapped around the outside of the two wires to achieve a storage function and make the device neater during use.

[0011] In a preferred embodiment, a fixing rope is connected to the top of the cable management roll, and the cable management roll is connected to the radiator through the fixing rope. The fixing rope is tied to the radiator, which can hold the cable management roll in place and prevent the cable management roll and the wire from shaking, thus affecting the stability of use.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model can significantly improve the cooling efficiency of the CPU by cooperating with the transducer body and the heat sink. At the same time, limit blocks are provided on both sides of the transducer body, and the heat sink is limited and fixed by the fixing plate, which can facilitate the staff to quickly complete the installation operation and effectively improve the installation efficiency. In addition, through the synergistic action of the plug rod and the compression spring, the fixing plate is fixed by the plug rod and the slot, which further improves the convenience of the overall structure installation and disassembly.

[0013] 2. By wrapping the cable management coil around the outside of the two wires, it can be stored neatly and is more tidy during use. In addition, tying the fixing rope to the radiator can hold the cable management coil in place and prevent the cable management coil and wires from shaking, which would affect the stability of use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Refer to the instruction manual appendix Figures 1-5 This utility model provides a CPU piezoelectric cooling transducer, including a transducer body 1. The top of the transducer body 1 is provided with a heat sink 2. The heat sink 2 is a device used to transfer heat from a heat source to the surrounding environment. The heat sink 2 is an air-cooled heat sink. It works by using heat dissipation fins and a fan to remove heat from the CPU surface. It has the advantages of high cost performance and convenient installation.

[0018] Next, limiting blocks 3 are fixedly provided on both sides of the transducer body 1. The heat sink 2 is located between the two limiting blocks 3. The front ends of the two limiting blocks 3 are hinged to fixing plates 4. The top of the two limiting blocks 3 is provided with mounting grooves 5. The mounting cylinder 6 is fixedly provided inside the mounting groove 5. The insertion rod 7 is slidably provided inside the mounting cylinder 6. The top of the two fixing plates 4 is provided with slots 8 that are adapted to the insertion rod 7. The insertion rod 7 is inserted into the slot 8. A compression spring 9 is connected between the top end of the insertion rod 7 and the inner wall of the mounting cylinder 6. The compression spring 9 can be compressed when squeezed. When the insertion rod 7 is not limited, the compression spring 9 can automatically restore its deformation and push the insertion rod 7 into the slot 8, thereby maintaining the fixation of the fixing plate 4.

[0019] Both insertion rods 7 are fixedly provided with pull rods 10 at their top ends. The top ends of the pull rods 10 pass through the mounting cylinder 6 and extend into the mounting groove 5. Both sides of the front end of the transducer body 1 are fixedly provided with wires 15 for connecting the circuit, so that the transducer body 1 is powered on to cool the CPU.

[0020] In actual use, first place the transducer body 1 on top of the CPU, then grasp the pull rod 10 to drive the insertion rod 7 upward. At this time, the compression spring 9 between the insertion rod 7 and the mounting cylinder 6 is squeezed. Then push the heat sink 2 from front to back between the two limit blocks 3. The bottom of the heat sink 2 contacts the top of the transducer body 1. After the heat sink 2 is pushed into place, close the two fixing plates 4. At the same time, release the pull rod 10. The compression spring 9 returns to its original position and pushes the insertion rod 7 downward to automatically insert into the slot 8, thereby fixing the fixing plate 4 to prevent the heat sink 2 from loosening and affecting the cooling effect. Finally, the operator connects the two wires 15 to the power supply motherboard. After the transducer body 1 is powered on, based on the Peltier effect, the direct current forces the charge to move in the P-type and N-type semiconductors, "transferring" heat at the microscopic level, so that one end becomes cold and absorbs heat, and the other end becomes hot and releases heat, thereby achieving the cooling of the CPU.

[0021] Refer to the instruction manual appendix Figure 2 The heat sink 2 is fixedly provided with connecting plates 11 on both sides. Each of the two connecting plates 11 has two symmetrically distributed fixing holes 12 on its top. Each fixing hole 12 has a fastening bolt 13 passing through it. The outer wall of the multiple fastening bolts 13 is fitted with the same fixing buckle 14. The fixing buckle 14 cooperates with the heat sink 2 to fix the CPU, thereby effectively improving the stability of the contact between the transducer body 1 and the CPU, and thus improving the normal cooling of the CPU.

[0022] Both wires 15 are fitted with cable management coils 16 on their outer walls. The cable management coils 16 can be made of flexible materials, such as rubber. When installing the cable management coils 16, the operator only needs to open the cable management coils 16 and then put them over the outside of the two wires 15. The cable management coils 16 will automatically close, thus tightening the two wires 15. By wrapping the cable management coils 16 around the outside of the two wires 15, they can be stored neatly and are easier for operators to quickly separate the wires 15. In addition, a fixing rope 17 is connected to the top of the cable management coils 16. The cable management coils 16 are connected to the radiator 2 through the fixing rope 17. By binding the fixing rope 17 to the radiator 2, the cable management coils 16 can be held in place, preventing the cable management coils 16 and the wires 15 from shaking and affecting the stability of use.

[0023] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
