Summary of the Invention

[0010] By adopting the above technical solution, a small part of the vibration is transmitted to the liquid cooling channel, and the small-amplitude vibration generated by the liquid cooling channel can disturb the cooling medium inside the liquid cooling channel to a certain extent, so as to improve the heat exchange efficiency between the cooling medium in the liquid cooling channel and the heat around the unit, and also improve the heat exchange efficiency between the cooling water in the heat exchange tube and the cooling medium in the liquid cooling channel.

[0011] Optionally, the heat exchange assembly includes a U-shaped heat exchange tube arranged in the liquid cooling channel, a water inlet pipe arranged at one end of the heat exchange tube, and a water outlet pipe arranged at the other end of the heat exchange tube, and the water inlet pipe and the water outlet pipe are both connected to the cooling water circulation system.

[0012] By adopting the above technical solution, the cooling water circulation system passes the cooling water into the heat exchange tube through the water inlet pipe, so that the cooling water in the heat exchange tube exchanges heat with the cooling medium in the liquid cooling channel, and the cooling water with increased temperature is discharged to the cooling water circulation system through the water outlet pipe.

[0013] Optionally, the size of the clearance port is larger than the size of the air inlet branch pipe and the air outlet branch pipe, and a second sound insulation buffer layer is provided between the clearance port and the air inlet branch pipe and the air outlet branch pipe respectively.

The second sound insulation buffer layer can not only buffer the liquid cooling channel, the air inlet branch pipe and the air outlet branch pipe, but also have a certain sound insulation effect.

[0015] Optionally, a sound absorbing layer is provided on a side of the liquid cooling channel close to the unit, and a plurality of sound absorbing and heat conducting strips are provided on the sound absorbing layer.

[0016] By adopting the above technical solution, the heat dissipated by the unit can be smoothly transferred to the liquid cooling channel, and the noise generated during the operation of the unit can also be absorbed.

[0017] Optionally, the liquid cooling channel is in a "return" shape, and an operation door is hinged at the top opening of the liquid cooling channel. An acoustic absorption layer is also provided inside the operation door.

[0027] S2: When the load of the unit is large, the cooling medium in the liquid cooling channel absorbs the heat around the unit to control the air inlet volume of the air inlet main pipe and the air outlet volume of the air outlet main pipe within a reasonable range.

[0028] S3: The cooling water circulation system passes the cooling water into the heat exchange tubes. The cooling water in the heat exchange tubes exchanges heat with the cooling medium in the liquid cooling channel.

Detailed Embodiments

[0041] The following is combined with the attached Figures 1 to 6This application is described in further detail.

[0042] The present application embodiment discloses a noise reduction structure for a machine room. Figure 1 The noise reduction structure of the machine room includes a machine room body 1, a base 2, a unit 3, an air cooling mechanism 4 and a liquid cooling mechanism. The interior of the machine room body 1 is a closed space. The base 2 is installed on the inner bottom of the machine room body 1, and the unit 3 is installed on the top of the base 2. In this embodiment, the unit 3 is a diesel generator set. The diesel generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy, and the diesel generator set is a prior art.

[0043] The air cooling mechanism 4 and the liquid cooling mechanism are both located around the unit 3 . The air cooling mechanism 4 can perform air cooling and heat dissipation on the unit 3 , and the liquid cooling mechanism can perform liquid cooling and heat dissipation on the unit 3 .

[0044] Reference Figure 2 and Figure 3 The liquid cooling mechanism includes a liquid cooling channel 5 and a heat exchange component 6. The cross-sectional area of ​​the base 2 is larger than the cross-sectional area of ​​the unit 3. A shock absorbing component 7 is installed on the top of the base 2. The liquid cooling channel 5 is installed above the base 2 through the shock absorbing component 7. The liquid cooling channel 5 is in the shape of a "U". The middle part of the liquid cooling channel 5 is a make way space. The liquid cooling channel 5 surrounds the unit 3, and there is a certain distance between the liquid cooling channel 5 and the unit 3. A cooling medium is contained in the liquid cooling channel 5. The cooling medium can exchange heat with the heat dissipated by the unit 3, so that the temperature of the cooling medium increases. The heat exchange component 6 is installed on the liquid cooling channel 5. The heat exchange component 6 can transfer the heat of the cooling medium in the liquid cooling channel 5 to the outside, so that the temperature of the cooling medium decreases.

[0045] Reference Figure 2 and Figure 4 The air cooling mechanism 4 includes an air inlet pipe 8, a plurality of air inlet branch pipes 9, an air outlet pipe 10 and a plurality of air outlet branch pipes 11. The air inlet pipe 8 and the air outlet pipe 10 are both located inside the machine room body 1. One end of the air inlet pipe 8 is fixedly connected to the air inlet end of the machine room body 1, and one end of the air outlet pipe 10 is fixedly connected to the air outlet end of the machine room body 1. Pipe fans 12 are installed in the air inlet pipe 8 and the air outlet pipe 10. The air inlet pipe 8 and the air outlet pipe 10 are respectively located on opposite sides of the liquid cooling channel 5. A plurality of air inlet branch pipes 9 are fixedly connected to one end of the air inlet pipe 8 close to the liquid cooling channel 5. A plurality of air outlet branch pipes 11 are fixedly connected to one end of the air outlet pipe 10 close to the liquid cooling channel 5. The liquid cooling channel 5 is provided with a plurality of make way openings 13. The make way openings 13 are connected to the make way space of the liquid cooling channel 5, and the make way openings 13 are not connected to the inside of the liquid cooling channel 5. The make way openings 13 are used for the air inlet branch pipe 9 and the air outlet branch pipe 11 to extend into the make way space of the liquid cooling channel 5.

[0046] The unit 3 generates a large amount of heat during operation, so it needs to be dissipated. When the air cooling mechanism 4 dissipates heat for the unit 3, the duct fans 12 in the air inlet pipe 8 and the air outlet pipe 10 are first started to make the interior of the machine room main body 1 a negative pressure state, so that the outside air is sucked into the air inlet pipe 8, and enters multiple air inlet branch pipes 9 along the air inlet pipe 8, so that the dispersed cooling air is blown to the unit 3, and the heat dissipated by the unit 3 is combined with the cooling air to form warming air. Since there is a certain distance between the unit 3 and the liquid cooling channel 5, the warming air can flow along the surface of the unit 3 and enter the air outlet branch pipe 11, and then be collected in the air outlet pipe 10 along the air inlet branch pipe 9 and discharged out of the machine room main body 1. It should be noted that, since the air inlet branch pipe 9 and the air outlet branch pipe 11 are respectively arranged on opposite sides of the unit 3, the cooling air of the air inlet branch pipe 9 is completely absorbed by the unit 3 and used as a cooling source. At the same time, it is ensured that the heated air discharged from the unit 3 is not easily mixed with the cooling air, thereby improving the heat dissipation effect of the unit 3 and making the rotation speed of the duct fan 12 not need to be too fast to achieve a better heat dissipation effect, thereby reducing the overall noise of the machine room.

[0047] In addition, when the load of the unit 3 is large, if the rotation speed of the duct fan 12 is increased, it is bound to generate large noise. At this time, a liquid cooling mechanism can be used to liquid-cool the unit 3 to control the air intake volume of the air inlet pipe 8 and the air outlet volume of the air outlet pipe 10 to a reasonable range, thereby achieving a balance between heat dissipation and noise reduction.

[0048] Reference Figure 3 The heat exchange assembly 6 includes a heat exchange tube 14, a water inlet pipe 15 and a water outlet pipe 16. The heat exchange tube 14 is installed inside the liquid cooling channel 5. The heat exchange tube 14 is U-shaped. The inside of the heat exchange tube 14 is not connected to the inside of the liquid cooling channel 5. The water inlet pipe 15 is connected to one end of the heat exchange tube 14, and the water outlet pipe 16 is connected to the other end of the heat exchange tube 14. The water inlet pipe 15 and the water outlet pipe 16 both extend out of the liquid cooling channel 5. The water inlet pipe 15 and the water outlet pipe 16 are both connected to the cooling water circulation system. In this embodiment, the cooling water circulation system is the prior art.

[0049] The cooling water circulation system passes the cooling water into the heat exchange tube 14 through the water inlet pipe 15, so that the cooling water in the heat exchange tube 14 exchanges heat with the cooling medium in the liquid cooling channel 5, which can transfer the heat of the cooling medium to the cooling water, increase the temperature of the cooling water, and reduce the temperature of the cooling medium. The cooling water with increased temperature is discharged to the cooling water circulation system through the water outlet pipe 16.

[0050] Reference Figure 1, in order to reduce the overall noise of the computer room main body 1, a sound insulation cavity 17 is provided inside the computer room main body 1, and the sound insulation cavity 17 is filled with sound insulation materials. The sound insulation materials can be mineral wool boards, polyurethane foams, glass wools, rubber sound insulation pads, etc. These materials can reduce the transmission of sound by reflecting or absorbing sound waves. In addition, a sound absorption board 18 is fixed to the inner wall of the computer room main body 1. The sound absorption board 18 can be a wave crest sound absorption sponge. The wave crest sound absorption sponge is a sponge with a concave-convex wave shape on one side, and its interior is filled with fine voids and semi-open pore structures, which can effectively absorb the sound wave energy.

[0051] Referring to Figure 5 , preferably, the shock absorption assembly 7 includes a convex platform 19, a relief groove 20, a shock absorber 21 and a first sound insulation buffer layer 22. The convex platform 19 is fixedly installed on the top of the base 2. The convex platform 19 is also in the shape of a "hui" character. The relief groove 20 is opened at the bottom of the liquid cooling channel 5. The relief groove 20 is not communicated with the inside of the liquid cooling channel 5. The relief groove 20 is formed in a circle. The convex platform 19 is slidably connected to the relief groove 20. The bottom end of the shock absorber 21 is fixed to the top of the convex platform 19. The top end of the shock absorber 21 is fixed to the inner top of the relief groove 20. And a plurality of shock absorbers 21 are provided. The first sound insulation buffer layer 22 is fixedly sleeved on the outside of the convex platform 19. The inner wall of the relief groove 20 is also fixedly connected with the first sound insulation buffer layer 22, and the two first sound insulation buffer layers 22 are mutually attached. In this embodiment, the first sound insulation buffer layer 22 is made of rubber material, and both the water inlet pipe 15 and the water outlet pipe 16 are flexible hoses.

[0052] Since the unit 3 generates certain vibrations during operation, these energies will be transmitted to the convex platform 19 through the base 2. The shock absorbers 21 and the first sound insulation buffer layer 22 can absorb the vibrations to a certain extent to reduce the vibrations of the liquid cooling channel 5. It should be noted that the shock absorbers 21 and the first sound insulation buffer layer 22 cannot absorb all the vibrations, and there will still be a small part of the vibrations transmitted to the liquid cooling channel 5. The small-amplitude vibrations generated by the liquid cooling channel 5 can disturb the cooling medium inside the liquid cooling channel 5 to a certain extent, so as to improve the heat exchange efficiency between the cooling medium in the liquid cooling channel 5 and the heat around the unit 3, and can also improve the heat exchange efficiency between the cooling water in the heat exchange tube 14 and the cooling medium in the liquid cooling channel 5. Since both the water inlet pipe 15 and the water outlet pipe 16 are flexible hoses, the flexible connection between the heat exchange tube 14 and the water inlet pipe 15 and the water outlet pipe 16 is realized. Rubber is a high-density material, which has a quite good sound insulation effect on high-frequency sounds, and also has the characteristics of shock absorption, waterproofing, and mildew prevention.

[0053] Referring to Figure 6Furthermore, the size of the clearance port 13 is larger than the size of the air inlet branch pipe 9 and the air outlet branch pipe 11, and the inner wall of the clearance port 13 is fixedly connected with a second sound insulation buffer layer 28, and the outer sides of the air inlet branch pipe 9 and the air outlet branch pipe 11 are also fixedly connected with a second sound insulation buffer layer 28, and the second sound insulation buffer layer 28 of the clearance port 13 is respectively fitted with the second sound insulation buffer layer 28 of the air inlet branch pipe 9 and the air outlet branch pipe 11. In this embodiment, the second sound insulation buffer layer 28 is made of rubber material. It should be noted that the size of the clearance port 13, the air inlet branch pipe 9 and the air outlet branch pipe 11 is restricted, so that when the liquid cooling channel 5 vibrates with a small amplitude, it is not easy to drive the air inlet branch pipe 9 and the air outlet branch pipe 11 to vibrate together, and the second sound insulation buffer layer 28 can not only buffer the liquid cooling channel 5, the air inlet branch pipe 9 and the air outlet branch pipe 11, but also have a certain sound insulation effect.

[0054] Reference Figure 4 Preferably, the air inlet pipe 8 and the air outlet pipe 10 are filled with a sound insulation medium 23, and the inner walls of the air inlet pipe 8 and the air outlet pipe 10 are fixed with a sound absorbing medium 24. In this embodiment, the sound insulation medium 23 can be a mineral wool board, polyurethane foam, glass wool, rubber sound insulation pad, etc., and the sound absorbing medium 24 can be a wave peak sound absorbing sponge. By filling the air inlet pipe 8 and the air outlet pipe 10 with the sound insulation medium 23, the sound insulation effect of the air inlet pipe 8 and the air outlet pipe 10 can be improved, and the setting of the sound absorbing medium 24 can absorb the noise generated when the air flows to a certain extent.

[0055] Reference Figure 5, Further, a sound-absorbing layer 25 is fixed on the side of the liquid cooling channel 5 close to the unit 3, and a plurality of sound-absorbing and heat-conducting strips 26 are fixed on the sound-absorbing layer 25. The sound-absorbing layer 25 and the sound-absorbing and heat-conducting strips 26 are bonded by glue. The lengths of the plurality of sound-absorbing and heat-conducting strips 26 are different, and the lengths of the sound-absorbing and heat-conducting strips 26 are set according to the horizontal distance between the outer side wall of the liquid cooling channel 5 and the unit 3, so that the horizontal distance between the sound-absorbing and heat-conducting strips 26 and the unit 3 remains unchanged. In this embodiment, the sound-absorbing layer 25 and the sound-absorbing and heat-conducting strips 26 can be flexible graphene materials. Due to their porous structure and large specific surface area, flexible graphene materials can effectively absorb and scatter sound waves, thus achieving a sound insulation effect. Because of their high thermal conductivity, flexible graphene materials can smoothly transfer the heat dissipated by the unit 3 to the liquid cooling channel 5. In addition, flexible graphene materials also have good elasticity. Even if the unit 3 touches the sound-absorbing and heat-conducting strips 26, it is not easy to cause damage to them. In this embodiment, the sound-absorbing layer 25 and the sound-absorbing and heat-conducting strips 26 can also be microporous polyurethane materials. Microporous polyurethane materials have a porous structure, and this structure can effectively absorb sound waves, thus achieving a sound insulation effect. After sound waves enter the micropores of the material, they will cause air vibration in the pores, generate friction with the pore walls, and convert sound energy into heat energy to achieve the purpose of sound absorption; due to their microporous structure, microporous polyurethane materials can effectively conduct heat, especially the microporous structure formed during the foaming process, which helps to improve the thermal conductivity of the materials.

[0056] Preferably, an operation door 27 is hinged at the top opening of the liquid cooling channel 5, and a sound-absorbing layer 25 is also fixed inside the operation door 27. In this embodiment, the sound-absorbing layer 25 can be mineral wool board, polyurethane foam, glass wool, rubber sound insulation pad, etc. The setting of the operation door 27 facilitates corresponding operations or maintenance on the unit 3 at its bottom, and the setting of the sound-absorbing layer 25 can reduce the noise of the unit 3. It should be noted that the operation door 27 and the liquid cooling channel 5 can be fixed by means of a lock catch or the like.

[0057] The embodiment of the present application also discloses a noise reduction method for a computer room noise reduction structure, and the noise reduction method includes the following steps:

[0058] S1: The air inlet main pipe 8 conveys the outside air to the air inlet branch pipe 9, and the cooling air blown out from the air inlet branch pipe 9 blows towards the unit 3. The heat dissipated by the unit 3 combines with the cooling air to form a temperature-rising air, and the temperature-rising air enters the air outlet branch pipe 11 and is discharged to the outside through the air outlet main pipe 10.

[0059] S2: When the load of the unit 3 is large, the cooling medium in the liquid cooling channel 5 absorbs the heat around the unit 3 to control the air intake volume of the air inlet main pipe 8 and the air outlet volume of the air outlet main pipe 10 within a reasonable range.

[0060] S3: The cooling water circulation system passes the cooling water into the heat exchange tube 14 through the water inlet pipe 15. The cooling water in the heat exchange tube 14 exchanges heat with the cooling medium in the liquid cooling channel 5. After the temperature of the cooling water in the heat exchange tube 14 rises, it returns to the cooling water circulation system through the water outlet pipe 16.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.

A method for reducing noise in a machine room, using a machine room noise reduction structure as claimed in any one of claims 1 to 5, characterized in that: The noise reduction method comprises the following steps: S1: The air inlet pipe (8) blows the external cooling air toward the unit (3), and the heat emitted by the unit (3) combines with the cooling air to form warming air. The warming air enters the air outlet branch pipe (11) and is discharged to the outside through the air outlet pipe (10); S2: When the load of the unit (3) is large, the cooling medium in the liquid cooling channel (5) absorbs the heat around the unit (3) to control the air intake of the air inlet pipe (8) and the air outlet of the air outlet pipe (10); S3: The cooling water circulation system passes cooling water into the heat exchange tube (14), and the cooling water in the heat exchange tube (14) exchanges heat with the cooling medium in the liquid cooling channel (5). After the temperature of the cooling water in the heat exchange tube (14) increases, it flows back to the cooling water circulation system through the water outlet pipe (16).
