Description

Technical Field

[0001] The invention relates to the field of liquid cooling and heat dissipation, and in particular to a low-noise and shock-absorbing liquid cooling device. Background Art

[0002] With the vigorous development of electronic technology, various electronic devices are gradually moving towards high performance and thinness. Therefore, it is necessary to improve performance as much as possible within a limited space volume. However, this also causes a significant increase in the heat energy generated by internal electronic components, which in turn leads to the traditional air cooling being unable to meet the heat dissipation needs of current electronic devices. Therefore, liquid cooling has become the mainstream heat dissipation method for many electronic devices.

[0003] Liquid cooling devices are often used with pumps to push the working liquid to increase the flow rate, thereby accelerating the circulation and increasing the heat dissipation efficiency. Currently, most general liquid cooling devices use either external pumps or internal pumps. The external pump is connected to the pump through a liquid infusion tube on the outside of the liquid cooling device, so that the working liquid can be pushed in the liquid cooling circulation system. Its advantage is that it is easy to connect and disassemble, but its disadvantage is that it takes up configuration space. Therefore, many electronic devices currently use internal pumps, which are placed inside the liquid cooling device to achieve the best driving effect on the internal working liquid, especially in liquid cooling radiators or liquid cooling heads.

[0004] However, due to the thinness limitation of various electronic devices, the area and volume that the liquid cooling device can attach to absorb heat are correspondingly limited. In this case, the flow rate and lift of the working liquid inside the liquid cooling device can only be further increased to improve the overall heat dissipation efficiency of the electronic device. However, as the speed of the pump increases to increase the flow rate and lift, the noise and vibration generated by the operation of the pump also increase significantly, causing the liquid cooling device to produce obvious noise and vibration, which seriously affects the user's experience and feelings. Therefore, how to design a low-noise, shock-absorbing liquid cooling device that can effectively reduce noise and vibration even when the internal pump is running at high speed is a shortcoming that needs to be improved urgently. Summary of the invention

[0005] The main purpose of the present invention is to effectively absorb the noise and vibration generated by the high-speed operation of the pump, and to allow the optical module to be fixed in the middle sleeve without relying on additional components.

[0006] In order to achieve the above-mentioned objectives, the present invention provides a low-noise and shock-absorbing liquid cooling device, including a main body, a pump, a light-emitting module, a middle sleeve, a shell and an optical module.

[0007] In one embodiment of the present invention, each sound absorbing and vibration reducing structure is in a triangle, pyramid, wave or wedge shape.

[0008] In one embodiment of the present invention, the optical module includes a first light-transmitting mirror and a supporting ring, and the supporting ring is supported between the light-emitting module and the first light-transmitting mirror.

[0011] In one embodiment of the present invention, the light-emitting module includes a mounting plate and a plurality of light-emitting elements. The mounting plate is disposed on the main body and shields a portion of the pump. Each light-emitting element is disposed on the mounting plate and is located in the internal space.

[0029] The detailed description and technical contents of the present invention will be described as follows with reference to the drawings. However, the drawings are only for illustration purposes and are not intended to limit the present invention.

[0030] The present invention provides a low-noise damping liquid cooling device. Figure 1 As shown, the low-noise and shock-absorbing liquid cooling device in this embodiment is connected to a liquid cooling head of a liquid cooling row B through a pair of infusion pipes A, but the present invention is not limited to this. In other embodiments, the low-noise and shock-absorbing liquid cooling device can also be a liquid cooling row B or other forms of liquid cooling devices. Please refer to Figures 2 to 6 As shown, the low-noise and shock-absorbing liquid cooling device of the present invention mainly includes a main body 10 , a pump 20 , a light-emitting module 30 , a middle sleeve 40 , a housing 50 and an optical module 60 .

[0031] In this embodiment, the main body 10 has a chamber 11 and a tank 12 on opposite sides, but the present invention is not limited thereto. Specifically, the chamber 11 is formed at the bottom of the main body 10, and the tank 12 is formed at the top of the main body 10. In addition, the main body 10 also has a liquid inlet interface 13 and a liquid outlet interface 14. In this embodiment, the liquid inlet interface 13 and the liquid outlet interface 14 are both configured on the same side of the main body 10, but the present invention is not limited thereto, and the liquid inlet interface 13 and the liquid outlet interface 14 can also be configured on different sides of the main body 10.

[0032] The pump 20 is generally disposed in the main body 10. Specifically, the pump 20 mainly includes a stator assembly 21 and a rotor assembly 22. The stator assembly 21 is disposed in the receiving groove 12, and the rotor assembly 22 is disposed in the chamber 11, so that most of the pump 20 is located in the main body 10. When the pump 20 is powered on, it can generate magnetic force, so that the rotor assembly 22 rotates relative to the stator assembly 21, thereby generating a suction force to push a coolant (not shown) in the main body 10 to flow. It should be noted that since the specific structure and actuation method of the stator assembly 21 and the rotor assembly 22 are both mature technologies and are well known to those with ordinary knowledge in the field, they will not be repeated here.

[0033] The light emitting module 30 is disposed on the main body 10 and shields a portion of the pump 20. The light emitting module 30 includes a mounting plate 31 and a plurality of light emitting elements 32. The mounting plate 31 is fixed on the main body 10 and shields a portion of the pump 20. Specifically, the mounting plate 31 is disposed on the top of the main body 10, and the mounting plate 31 shields the stator assembly 21 of the pump 20 and the receiving groove 12 of the main body 10. Each light emitting element 32 is disposed on the mounting plate 31. In this embodiment, each light emitting element 32 is an LED and is arranged in a circular shape on the mounting plate 31, but the present invention is not limited thereto.

[0034] In this embodiment, the middle sleeve 40 can be a sound-absorbing and cushioning material such as PU foam, PE foam or polyester fiber foam, but the present invention is not limited thereto, as long as the cushioning material has a sound absorption coefficient greater than 0.2. The middle sleeve 40 is a hollow cylindrical structure. The middle sleeve 40 is sleeved on the outside of the main body 10, and the middle sleeve 40 has an inner wall 41, an internal space 42 and a plurality of sound-absorbing and shock-absorbing structures 43. Specifically, the inner wall 41 surrounds the internal space 42. The main body 10, the mounting plate 31 and each light-emitting element 32 of the light-emitting module 30, and the stator assembly 21 and the rotor assembly 22 of the pump 20 are all located in the internal space 42 surrounded by the inner wall 41. It is worth mentioning that, since the pump 20 is disposed in the main body 10 , the pump 20 is not directly located in the internal space 42 (ie, separated by the main body 10 and the mounting plate 31 ), but the pump 20 is actually still surrounded by the inner wall 41 of the middle sleeve 40 and located in the internal space 42 .

[0035] Each sound-absorbing and shock-absorbing structure 43 extends from the inner wall 41. In the present embodiment, each sound-absorbing and shock-absorbing structure 43 is arranged on the inner wall 41 in a matrix arrangement, but the present invention is not limited thereto, and the arrangement of each sound-absorbing and shock-absorbing structure 43 should be adjusted accordingly according to different needs. Each sound-absorbing and shock-absorbing structure 43 is in a triangular, pyramidal, wavy or wedge shape. The sound-absorbing and shock-absorbing structure 43 in the present embodiment is in a pyramidal shape, but the present invention is not limited thereto. In addition, since the middle sleeve 40 in the present embodiment is made of sound-absorbing and cushioning materials such as PU foam, PE foam or polyester fiber foam, the middle sleeve 40 has deformable and compressible properties.

[0036] The housing 50 is fixed to the main body 10 and covers the middle sleeve 40. Specifically, the housing 50 is a hollow cylindrical structure. The top of the housing 50 has a through hole 51. The through hole 51 is connected to the inner space 42 of the middle sleeve 40. In this embodiment, the inner diameter of the through hole 51 is greater than or equal to the diameter of the inner wall 41, so that the light emitted by the light-emitting module 30 can be emitted from the through hole 51 without being affected by it.

[0037] The optical module 60 is clamped between the sound absorbing and damping structures 43 of the middle sleeve 40, and the optical module 60 is located between the light emitting module 30 and the through hole 51. Thus, since the middle sleeve 40 has the characteristics of being deformable and compressible, the optical module 60 can be clamped between the sound absorbing and damping structures 43 of the middle sleeve 40, and can be fixed in the middle sleeve 40 without relying on additional components. In addition, since the middle sleeve 40 is sleeved on the main body 10 and surrounds the light emitting module 30 and the pump 20 at the same time, when the pump 20 is operating efficiently, the middle sleeve 40 can effectively absorb the noise and vibration generated by the pump 20.

[0038] Further explanation, the optical module 60 in this embodiment includes a first light-transmitting mirror 61 and a support ring 62, but the present invention is not limited to this. For example, in other embodiments, the first light-transmitting mirror 61 can also be replaced with a focusing lens or a color-changing lens to produce different optical effects. The support ring 62 is supported between the mounting plate 31 of the light-emitting module 30 and the first light-transmitting mirror 61 to support the first light-transmitting mirror 61 and enable it to remain stable. In addition, the low-noise shock-absorbing liquid cooling device of the present invention also includes a second light-transmitting mirror 70. The housing 50 also has a mounting groove 52. The mounting groove 52 is located at the top of the housing 50 and is connected to the through hole 51. The mounting groove 52 is larger than the through hole 51, so that the second light-transmitting mirror 70 will not cover the through hole 51 when installed in the mounting groove 52. In this embodiment, the first light-transmitting mirror 61 is a one-way mirror and has a total reflection surface 611 on the side away from the light-emitting module 30, and the second light-transmitting mirror 70 has a semi-reflection surface 71 on the side facing the first light-transmitting mirror 61, whereby the light-emitting module 30, the optical module 60 and the second light-transmitting mirror 70 can together form an infinite reflection mirror (not numbered in the figure), so that the light emitted by the light-emitting module 30 produces a specific visual effect, but the present invention is not limited thereto. Specifically, the total reflection surface 611 and the semi-reflection surface 71 in this embodiment can be formed on the first light-transmitting mirror 61 and the second light-transmitting mirror 70 through an optical coating process.

[0039] Further explanation, since the first light-transmitting mirror 61 is a one-way mirror, the light emitted by the light-emitting module 30 cannot penetrate the first light-transmitting mirror 61 again after penetrating the first light-transmitting mirror 61, thereby effectively ensuring the brightness of the light. And since the first light-transmitting mirror 61 has a total reflection surface 611, and the second light-transmitting mirror 70 has a semi-reflection surface 71, when the light is emitted to the second light-transmitting mirror 70, part of the light will penetrate the second light-transmitting mirror 70 to the outside, and the rest of the light will be affected by the semi-reflection surface 71 and reflect, thereby being emitted back to the first light-transmitting mirror 61, and being reflected by the total reflection surface 611 of the first light-transmitting mirror 61, and then being emitted to the second light-transmitting mirror 70. In this way, the infinite reflector in this embodiment can generate an infinite number of virtual images of light sources, thereby generating a special visual effect that is infinitely extended like a light tunnel or a light abyss.

[0040] See also Figure 2 , Figure 3 and Figure 6As shown, the noise-absorbing liquid cooling device of this embodiment also includes a partition component 80 and a base 90. The partition component 80 is arranged at the bottom of the main body 10 and shields the chamber 11. The base 90 is fixed to the bottom of the main body 10 and covers the partition component 80. The base 90 is used to attach to a heat source (not shown) to absorb the heat energy generated when the heat source is in operation. The partition component 80 has a through groove group 801. The base 90 has a plurality of fins 91 arranged parallel to each other, so that a plurality of channels 92 are formed between the fins 91. Each channel 92 is connected to the chamber 11 through the through groove group 801 of the partition component 80. In addition, a liquid inlet cavity 802 is formed between the base 90 and the partition component 80. The liquid inlet interface 13 is connected to the liquid inlet cavity 802. The liquid outlet interface 14 is connected to the chamber 11. Thus, the coolant can enter the liquid inlet cavity 802 from one of the liquid infusion tubes A through the liquid inlet interface 13, and flow through each channel 92 to take away the heat energy absorbed by the base 90 and conducted to each fin 91. Then, the suction force generated by the rotation of the pump 20 allows the coolant to flow into the chamber 11 through the through groove group 801 of the partition component 80, and finally leave the low-noise shock-absorbing liquid cooling device of the present invention from the liquid outlet interface 14. In this embodiment, the partition component 80 includes a partition plate 81 and a guide plate 82. The partition plate 81 is arranged between the guide plate 82 and the chamber 11 to prevent the coolant in the chamber 11 from flowing back into the liquid inlet cavity 802 and causing interference. The guide plate 82 is used to rectify and guide the coolant in each channel 92, so that the coolant can enter the chamber 11 through the partition plate 81.

[0041] The low-noise and shock-absorbing liquid cooling device of the present invention can effectively absorb the noise and vibration generated by the high-speed operation of the pump 20 by mounting the middle sleeve 40 on the main body 10 and surrounding the light-emitting module 30 and the pump 20, and clamping the optical module 60 between the sound-absorbing and shock-absorbing structures 43 of the middle sleeve 40, so that the optical module 60 can be fixed in the middle sleeve 40 without relying on additional components.

[0042] In summary, the above disclosure of the present invention is to enable those with ordinary knowledge in the field to clearly understand the technical content of the present invention and implement it accordingly, and is not intended to limit the scope of patent protection of the present invention. In addition, the present invention may of course have other unlisted embodiments. Without departing from the spirit and essence of the present invention, those familiar with the art should be able to evolve various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the patent applied for by the present invention.
