Description

Technical Field

[0001] The present invention belongs to the technical field of experimental equipment, and in particular relates to a flexible liquid cooling heat dissipation and vibration reduction structure and a liquid cooling heat dissipation and vibration reduction device. Background Art

[0002] Currently, the grinding machines on the market are generally noisy and vibrate violently during operation, requiring the use of noise reduction equipment, which seriously affects the surrounding environment. Furthermore, the grinding machines can generate significant heat during operation, with the temperature rising rapidly. In actual operation, if the machine overheats, it is necessary to shut down the machine and suspend operation until the machine cools down before resuming work.

[0003] In terms of vibration reduction and noise reduction, there are the following problems: 1. It is not very flexible, relatively fixed, and cannot be moved at will; 2. It cannot dissipate heat well, resulting in high temperatures when the instrument is in operation, or requires the use of refrigeration equipment such as air conditioners; 3. Most of the current vibration reduction and noise reduction equipment is mainly aimed at large instruments, and there are fewer related devices for small instruments. For example, when performing comprehensive noise reduction on large instruments and equipment, decorative walls or ceilings such as glass wool and foam plastics are often used. Although they have a noise reduction effect, the overall installation is relatively cumbersome and requires coordination with rooms or other fixed devices. It has great limitations and is time-consuming and labor-intensive when changing the use of the room. Heat dissipation requires the installation of additional air conditioners. For equipment with high heat generation, this heat dissipation method is not effective. For this reason, it is very necessary to develop a flexible liquid-cooled heat dissipation and vibration reduction structure and a liquid-cooled heat dissipation and vibration reduction device.

[0022] The present invention is further described below with reference to the embodiments and drawings, but the present invention is not limited in any way. Any changes or substitutions made based on the teachings of the present invention fall within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figure 1 ~Attached Figure 2As shown, the flexible liquid cooling and heat dissipation vibration reduction structure of this embodiment includes a substrate 1, a boss 2, a flexible elastic cover 3, and a heat conducting sheet 4. The substrate 1, the boss 2, and the heat conducting sheet 4 are all made of copper, and the flexible elastic cover 3 is made of rubber. The boss 2 and the flexible elastic cover 3 are both hemispherical. The boss 2 is provided on the substrate 1, and the flexible elastic cover 3 covers the boss 2, with a liquid flow gap between the flexible elastic cover 3 and the boss 2. A liquid inlet pipe 5 and a liquid outlet pipe 6 are respectively provided on the side of the flexible elastic cover 3, and the heat conducting sheet 4 is provided at the top center of the flexible elastic cover 3.

[0025] The surface of the flexible elastic cover 3 of the flexible liquid cooling and vibration reduction structure of this embodiment is brought into contact with the surface of the object to be cooled. Since the flexible elastic cover 3 has elastic force, the flexible elastic cover 3 is compressed and deformed after the contact. At this time, there is a gap between the heat conducting plate 4 and the boss 2. The coolant continuously flows into the gap between the flexible elastic cover 3 and the boss 2 through the liquid inlet pipe 5, while taking away part of the heat transferred through the heat conducting plate 4 and part of the heat transferred through the flexible elastic cover 3 and dissipating it from the liquid outlet pipe 6; since the substrate 1 and the boss 2 both have good thermal conductivity, part of the heat will also be dissipated outwards through the substrate 1 and the boss 2.

[0026] Example 2

[0027] The flexible liquid cooling and heat dissipation vibration reduction structure of this embodiment is based on the embodiment 1, wherein the base plate 1 and the boss 2 are integrally formed into an integrated structure;

[0028] The surface of the flexible elastic cover 3 of the flexible liquid cooling and vibration reduction structure of this embodiment is in contact with the surface of the heating part of the motor to assist in dissipating heat from the heating part. The vibration generated by the motor itself reacts with the flexible elastic cover 3 and the coolant inside, thereby reducing vibration.

[0029] Example 3

[0030] As attached Figure 1 ~Attached Figure 4 As shown, the flexible liquid cooling and vibration damping structure of this embodiment is based on the embodiment 1. There are nine flexible liquid cooling and vibration damping structures and they are arranged adjacent to each other in three rows and three columns. In two adjacent flexible liquid cooling and vibration damping structures, the liquid outlet pipe of one flexible liquid cooling and vibration damping structure serves as the liquid inlet pipe of the other flexible liquid cooling and vibration damping structure, so that the coolant flows through different flexible liquid cooling and vibration damping structures and forms a serpentine liquid flow, that is, the coolant enters from the first flexible liquid cooling and vibration damping structure and is discharged from the last flexible liquid cooling and vibration damping structure;

[0031] The surface of the flexible elastic cover 3 of the flexible liquid cooling and vibration reduction structure of this embodiment is brought into contact with the surface of a larger object to be cooled. The object is non-vibrating, and the heat conducting plate 4 is pressed against the boss 2. Multiple flexible liquid cooling and vibration reduction structures increase the contact area. While the heat conducting plate 4 and the top of the boss 2 are exchanging heat, the coolant flows around the boss 2 and takes away the heat.

[0032] Example 4

[0033] The flexible liquid cooling and vibration reduction structure of this embodiment is based on the embodiment 1. The flexible liquid cooling and vibration reduction structures are provided in three rows and arranged adjacent to each other. In two adjacent flexible liquid cooling and vibration reduction structures, the liquid outlet pipe of one flexible liquid cooling and vibration reduction structure is connected to the liquid inlet pipe of the other flexible liquid cooling and vibration reduction structure.

[0034] The surface of the flexible elastic cover 3 of the flexible liquid cooling and vibration reduction structure of this embodiment is brought into contact with the surface of the heating part of the large motor to assist in dissipating the heat from the heating part. The vibration generated by the motor itself reacts with the flexible elastic cover 3 and the coolant inside, thereby reducing vibration.

[0035] The working principle and working process of the flexible liquid-cooled heat dissipation and vibration reduction structure of the present invention are as follows: coolant is introduced into the gap between the boss 2 and the flexible elastic cover 3 through the liquid inlet pipe 5. The coolant can specifically be a cooling medium such as water or cooling oil; the flexible elastic cover 3 deforms after contacting the surface of the object to be cooled; the heat of the object is transferred through the heat conducting plate 4 and the flexible elastic cover 3 and discharged from the liquid outlet pipe 6 through the coolant; when the object vibrates, the vibration is reduced by the action of the flexible elastic cover 3 and the liquid inside it.

[0036] Example 5

[0037] As attached Figure 1 ~Attached Figure 5 As shown, the liquid cooling and heat dissipation vibration reduction device of this embodiment includes the flexible liquid cooling and heat dissipation vibration reduction structure, and also includes a box body 7, a platform 8, and a vibration reduction spring 9. The box body 7 is composed of a base plate 1, and the box body 7 is provided with a side-opening box door. The platform 8 is located in the box body 7, and the upper end of the vibration reduction spring 9 is connected to the bottom of the platform 8, and the lower end is connected to the bottom of the box body 7. The inner wall of the box body 7 is provided with a flexible liquid cooling and heat dissipation vibration reduction structure, and there is no flexible liquid cooling and heat dissipation vibration reduction structure at the door opening corresponding to the box door. The flexible liquid cooling and heat dissipation vibration reduction structures of each inner wall are connected by a liquid inlet pipe and a liquid outlet pipe. In adjacent inner walls, a flexible liquid cooling and heat dissipation vibration reduction structure in one inner wall is connected to a flexible liquid cooling and heat dissipation vibration reduction structure in another inner wall through a liquid inlet pipe and a liquid outlet pipe. A liquid feed pipe 10 and a liquid discharge pipe 11 are respectively provided on the outside of the box body 7, and the liquid feed pipe 10 and the discharge pipe 11 are respectively connected to different flexible liquid cooling and heat dissipation vibration reduction structures;

[0038] The FSJ-A03E1 sample grinder has a power of 300W, a four-blade stainless steel blade, and a maximum capacity of 200g. During operation, it grinds samples for 1 minute and then stops for 2 minutes. Furthermore, the grinder generates noticeable heat, vibrates violently, and makes a loud noise, reaching up to 100 decibels.

[0039] Open the door, place the FSJ-A03E1 grinding machine loaded with 100g of sample to be processed on the platform 8 of this device, and then close the door; pass the coolant into the flexible liquid cooling and vibration reduction structure through the liquid feeding pipe 10, with a flow rate of 1dm 3 / min, the flexible elastic cover 3 stands up after the liquid is passed into it and contacts the grinding machine casing, and the coolant is finally discharged from the drain pipe 11, wherein the coolant is externally connected to a cooling circulation device to achieve external cooling and continuous circulation of the coolant; during the operation of the grinding machine, the noise is significantly reduced, about 50 decibels; the temperature is detected immediately after the grinding machine is completed, and the temperature is significantly lower than that of the grinding machine that does not use this device; it can be seen that the device of the present invention can significantly reduce vibration, reduce noise and temperature.

[0042] The TP-air compressor has a pump power of 2040W and produces a huge noise when working, with a maximum noise level of 105 decibels, strong vibration, and obvious heat generation.

[0043] Place the TP-air compressor on platform 8, pass the cable of the TP-air compressor through the cable hole, and the air inlet end of the air compressor corresponds to the air inlet of the box; the coolant flow rate is controlled at 10dm 3 / min; when the air compressor is running, the temperature is significantly reduced, the vibration is weakened, and the noise is reduced to about 60 decibels; it can be seen that the device of the present invention can significantly reduce vibration, reduce noise and temperature.

[0044] The working principle and working process of the liquid cooling and vibration reduction device of the present invention are as follows: the box body 7 forms a relatively closed space, and cooperates with the vibration reduction spring 9 and the flexible liquid cooling and vibration reduction structure to enhance the vibration reduction effect and reduce the operating noise of the equipment; and there are flexible liquid cooling and vibration reduction structures all around the equipment to cool the equipment in all directions, and the cooling effect can be controlled by controlling the flow rate of the coolant; after the equipment is completed, it can be removed from the device.
