Description

Technical Field

[0001] The invention relates to the technical field of heat dissipation in a computer room, and in particular to a high-efficiency energy-saving heat dissipation system for a large-scale storage unit in a computer room of a power system. Background Art

[0002] Information rooms, such as data center rooms and core rooms, are important places for placing communication electronic equipment. With the rapid development of global communications, the Internet, the Internet of Things, e-commerce, and cloud computing industries, both communication operators and governments, enterprises, etc. are building a large number of electronic information rooms. The electronic equipment in these rooms will continue to generate heat during operation. In order to ensure the normal operation of information electronic equipment, special air conditioners are generally installed in electronic information rooms to cool the information electronic equipment. The integration of information electronic equipment is getting higher and higher, and its heat density is getting higher and higher. As a result, the load on the dedicated air conditioner in the room will become larger and larger, and the energy consumption will also be higher and higher. Under the same conditions, traditional room air conditioners can only increase the number of air conditioners or replace room air conditioners with larger cooling capacity, so as to reduce the effective area of ​​the room. Data show that the energy consumption of information electronic equipment currently accounts for 45% of the overall energy consumption of the room, while the energy consumption of refrigeration equipment such as dedicated air conditioners in the room accounts for 40% of the overall energy consumption of the room, which is close to or exceeds the energy consumption of information electronic equipment. It can be seen that by improving the refrigeration system of the communication room, the communication room still has a large space for energy saving.

[0003] Chinese patent application number "CN201410755258.2" discloses an energy-saving computer room cooling system, including a precision air conditioner, a static pressure box, a return air device, a fully visible heat exchanger, a cooling module and an intelligent server cabinet. The cooling system is composed of a precision air conditioner, a static pressure box, an intelligent server cabinet, a return air device and a fully visible heat exchanger to form an internal circulation. The cooling system is composed of a fully visible heat exchanger and a cooling module to form an external circulation. The internal circulation of the computer room is coupled with the external circulation. When the outdoor air temperature is high, the air required by the server is first partially reduced in temperature by the external circulation, and then reduced to the required nominal value by the precision air conditioner; when the outdoor temperature is low, the air required by the server directly passes through the external circulation to reach the required nominal value. The above system can exchange heat between the higher temperature air in the computer room and the lower temperature air outside without affecting the internal environment of the computer room.

[0004] However, the system will occupy a certain amount of space inside the computer room, which is prone to produce a heat island effect, resulting in a high temperature in the computer room. In addition, the system cannot directly dissipate heat to the equipment in processing, resulting in the temperature of the working equipment surface remaining high during the double circulation process.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention can perform individual heat dissipation for each memory unit by installing the memory unit separately in an independent cabinet and cooperating with the heat dissipation components arranged on the independent cabinet, and directly absorb the hot air generated by the memory unit when it is working and guide it to the water cooling system for cooling treatment, and discharge it into the interior of the computer room body, thereby avoiding the high temperature inside the computer room body. The precision air-conditioning system is used to cool the interior of the computer room body, which not only ensures the direct cooling of the memory unit but also avoids a substantial increase in the overall temperature of the computer room body, making it convenient for staff to enter the interior of the computer room body to inspect the memory unit and perform other operations.

[0019] 2. The present invention adopts a non-enclosed installation method for the storage unit through an independent cabinet, which can very conveniently dissipate part of the heat generated by the storage unit during operation directly into the overall air in the computer room, thereby avoiding the effect of the surface heat of the storage unit being unable to dissipate due to the enclosed installation, resulting in the reheating of the storage unit.

[0020] 3. The present invention forms an air flow path inside the storage unit through the cooperation of the blowing unit and the exhaust unit. The heat generated by the storage unit during operation is absorbed by the exhaust unit and transported from the first intake pipe to the heat dissipation unit, so that each storage unit can perform independent heat dissipation. When a problem occurs in the heat dissipation component of one of the storage units, it will not cause a significant increase in the overall temperature. When the heat dissipation component is repaired separately, it will not affect the normal operation of other storage units.

[0021] 4. The present invention conducts the hot air absorbed by the exhaust unit to the water cooling system under the floor of the computer room body through the heat dissipation unit. The air storage box of the heat dissipation unit wraps the output end of the second fan to prevent the hot air from directly entering the interior of the computer room body. The hot air in the air storage box is conducted to the first copper tube through the first bellows. The first copper tube is immersed in a water tank filled with cooling liquid. The hot air completes heat conduction at the first copper tube to reduce the temperature of the air. The cooled air enters the interior of the computer room body through the second bellows, reducing the temperature impact on the interior of the computer room body.

[0022] 5. The present invention achieves sealing of the connection position by arranging a sealing ring at the connection position between the first copper tube, the first bellows and the second bellows.

[0023] 6. The present invention opens a plurality of openings on the floor of the machine room body and installs a detachable closing plate, which facilitates the passage of the first bellows and the second bellows while preventing the liquid in the water tank under the floor from entering the upper floor through the openings.

[0024] 7. The present invention cools down the interior of the computer room body by installing a precision air-conditioning system on the computer room body in cooperation with a plurality of gas-convenient ventilation fans provided on the computer room body to circulate gas. Since part of the heat generated by the storage unit has been processed by the water cooling system, the temperature regulation inside the computer room body is relatively simple, and the power of the fan of the precision air-conditioning system is reduced, thereby solving the problem of high power of the heat dissipation system.

[0025] 8. The present invention provides space for the installation of a water tank by installing the floor of the computer room body on a support frame, so that there is only one device, a control device, in the computer room body in addition to the storage unit, thereby releasing a large amount of space in the computer room body and avoiding the heat island effect caused by too many devices in the computer room body causing the temperature inside the computer room body to rise.

DETAILED DESCRIPTION

[0042] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figures 1 to 4 As shown, this application provides:

[0044] A high-efficiency and energy-saving heat dissipation system for large-scale storage units in a power system computer room, comprising a computer room body 1 and a plurality of storage units 2 placed in the computer room body 1, a precision air-conditioning system 3 for reducing the temperature in the computer room body 1 and an independent cabinet 4 for individually placing the storage units 2 are installed on the computer room body 1, a heat dissipation component 5 for dissipating heat for a single storage unit 2 is arranged on the independent cabinet 4, the heat dissipation component 5 comprises a blowing unit 5a with a working end facing the storage unit 2 and an exhaust unit 5b for absorbing hot air in the storage unit 2, the exhaust unit 5b is connected to a water cooling system 6 arranged at the bottom of the computer room body 1 through a heat dissipation unit 5c, and the water cooling system 6 is used to cooperate with the heat dissipation unit 5c to absorb the heat in the exhaust unit 5b.

[0045] Based on the above embodiments, the technical problem that the present application intends to solve is how to dissipate heat more efficiently for the storage unit 2 and avoid the internal space of the computer room body 1 being too dense and the temperature inside the computer room body 1 being too high. To this end, the present application adjusts the overall problem in the computer room body 1 by setting a precision air conditioning system 3 on the computer room body 1. The storage units 2 placed in the computer room body 1 are individually installed in independent cabinets 4. The heat dissipation components 5 provided on the independent cabinets 4 can dissipate heat for each storage unit 2 individually. The heat dissipation components 5 blow air to the storage unit 2 through the blowing unit 5a to accelerate the air flow speed on the surface of the storage unit 2, thereby taking away a large amount of heat generated by the storage unit 2 during operation. The exhaust unit 5b inhales air to the storage unit 2 in cooperation with the blowing unit 5a. An air flow path is formed, and the exhaust unit 5b directly absorbs the hot air and guides it to the water cooling system 6 through the heat dissipation unit 5c. The water cooling system 6 can absorb the heat to a certain extent, and then discharge the cooled air to the inside of the computer room body 1, thereby avoiding the high temperature inside the computer room body 1. In conjunction with the precision air-conditioning system 3, the inside of the computer room body 1 is cooled, which not only ensures the direct cooling of the storage unit 2, but also avoids a substantial increase in the overall temperature of the computer room body 1, making it convenient for staff to enter the computer room body 1 to inspect the storage unit 2 and other operations.

[0046] Further, such as Figure 3 and 4 As shown:

[0047] The independent cabinet 4 includes a bottom base 4a, and a top plate 4b is arranged above the bottom base 4a. The distance between the bottom base 4a and the top plate 4b is greater than the height of the storage unit 2. The bottom base 4a and the two sides of the top plate 4b are connected by side support plates 4c. The top plate 4b is provided with a plurality of first ventilation holes 4b1, and the side support plates 4c are provided with a plurality of second ventilation holes 4c1.

[0048] Based on the above embodiments, the technical problem that the present application intends to solve is how to install the memory unit 2 in the independent cabinet 4 to ensure its own heat dissipation performance. To this end, the present application forms an independent cabinet 4 by splicing the bottom base 4a, the top plate 4b and the side support plate 4c. The bottom base 4a, the top plate 4b and the side support plate 4c are all made of metal materials to ensure their own structural stability. The channel between the side support plates 4c is used for the placement of the memory unit 2. The memory unit 2 is placed on the bottom base 4a. The top plate 4b and the side support plate 4c are both provided with a plurality of dense first ventilation holes 4b1 and second ventilation holes 4c1 to facilitate the heat dissipation of the memory unit 2. The non-enclosed installation method adopted by the independent cabinet 4 for the memory unit 2 can be very convenient for the heat generated by the memory unit 2 during operation to be directly dissipated to the overall air in the machine room body 1, avoiding the influence of the memory unit 2 being heated again due to the inability to dissipate the surface heat of the memory unit 2 caused by the enclosed installation.

[0049] Further, such as Figures 5 to 7 As shown:

[0050] The blowing unit 5a includes a first fan 5a1 installed on the top of the top plate 4b of the independent cabinet 4, and a first mounting port 4b2 matching the shape of the first fan 5a1 is arranged on the top of the top plate 4b. The blowing end of the first fan 5a1 is arranged toward the inside of the independent cabinet 4, and a first closing box 5a2 is arranged below the first fan 5a1. A plurality of first air inlet pipes 5a3 are arranged below the first closing box 5a2. The first air inlet pipes 5a3 are fixedly connected to different height layers of the storage unit 2 through a first connecting member 5a4, and the first air inlet pipes 5a3 are used to transport gas to different layers of the storage unit 2.

[0051] The exhaust unit 5b includes a second fan 5b1 installed on the outside of the bottom of the side support plate 4c of the independent cabinet 4, and a first mounting port 4b2 matching the shape of the second fan 5b1 is provided at the connection position between the side support plate 4c and the second fan 5b1. The blowing end of the second fan 5b1 is arranged toward the outside of the independent cabinet 4, and the second fan 5b1 is provided with a second closing box 5b2 on the inner side of the independent cabinet 4. A plurality of first air intake pipes 5b3 are provided above the second closing box 5b2. The first air intake pipes 5b3 are fixedly connected to different height layers of the storage unit 2 through a second connecting member 5b4, and the first air intake pipes 5b3 are used to absorb hot air in different layers of the storage unit 2.

[0052] Based on the above embodiments, the technical problem that the present application intends to solve is that the heat dissipation component 5 performs independent heat dissipation treatment on a separate storage unit 2 so as to improve the heat dissipation effect of each storage unit 2 when working. To this end, the present application places a single storage unit 2 through an independent cabinet 4. The storage unit 2 is usually divided into a plurality of grids, and a plurality of storage devices are installed in each grid. The heat dissipation component 5 blows air into each grid through the blowing unit 5a to accelerate the movement of heat on the surface of the storage device inside the grid. The blowing unit 5a delivers air to the storage unit 2 through the first fan 5a1 installed on the top of the independent cabinet 4. The first closing box 5a2 is installed under the air inlet of the first fan 5a1 to prevent wind loss. The first closing box 5a2 cooperates with the first air intake pipe 5a3 to transport wind to different grids. The first connecting member 5a4 is used to connect the connecting end of the first air intake pipe 5a3 to different grids of the storage unit 2. A connecting pipe is set to cooperate with the first connecting piece 5a4. After the gas enters the storage unit 2, it is transported to one side. The exhaust unit 5b installed at the bottom of the other side of the independent cabinet 4 exhausts the inside of the storage unit 2 through the first air intake pipe 5b3 connected to the storage unit 2 and the second fan 5b1. The cooperation between the blowing unit 5a and the exhaust unit 5b forms an air flow path inside the storage unit 2. The heat generated by the storage unit 2 during operation is absorbed by the exhaust unit 5b and transported from the first air intake pipe 5b3 to the heat dissipation unit 5c, so that each storage unit 2 can dissipate heat separately. When a problem occurs in the heat dissipation component 5 of one of the storage units 2, it will not cause a significant increase in the overall temperature. When the heat dissipation component 5 is repaired separately, it will not affect the normal operation of other storage units 2, nor will it affect the temperature in the computer room body 1, so that it is convenient for staff to enter the computer room body 1 for maintenance.

[0053] Further, such as Figure 2 , Figure 6 , Figure 8 and Fig. 9 As shown:

[0054] The heat dissipation unit 5c includes an air storage box 5c1 wrapped around the outside of the second fan 5b1, and a first bellows 5c2 extending vertically downward is arranged below the air storage box 5c1. The first bellows 5c2 passes through the floor 1a of the machine room body 1, and one end of the first bellows 5c2 is connected to the first copper tube 5c3, and one end of the first copper tube 5c3 is connected to the second bellows 5c4. One end of the second bellows 5c4 passes through the floor 1a toward the inside of the machine room body 1.

[0055] The water cooling system 6 includes a water tank 6a installed at the bottom of the floor 1a of the machine room body 1, the water tank 6a is filled with cooling liquid, the first copper tube 5c3 of the heat dissipation component 5 is immersed in the water tank 6a and in contact with the cooling liquid, and the water cooling system 6 also includes a control device 6b arranged in the machine room body 1, and the control device 6b is used to control the discharge of the liquid in the water tank 6a.

[0056] Based on the above embodiments, the technical problem that the present application intends to solve is how to prevent the storage unit 2 from directly discharging a large amount of heat into the overall space of the computer room body 1, causing the overall temperature inside the computer room body 1 to rise. To this end, the present application conducts the hot air absorbed by the exhaust unit 5b to the water cooling system 6 under the floor 1a of the computer room body 1 through the heat dissipation unit 5c. The air storage box 5c1 of the heat dissipation unit 5c wraps the output end of the second fan 5b1 to prevent the hot air from directly entering the computer room body 1. The hot air in the air storage box 5c1 is conducted to the first copper tube 5c3 through the first corrugated pipe 5c2. The first copper tube 5c3 has a certain thermal conductivity, and the first copper tube 5c3 is immersed in a water tank 6a filled with cooling liquid. The cooling liquid can be water or cooling oil. The hot air completes the heat conduction at the first copper tube 5c3 to reduce the temperature of the air. The cooled air enters the interior of the computer room body 1 through the second bellows 5c4, reducing the temperature impact on the interior of the computer room body 1. The presence of the first bellows 5c2 and the second bellows 5c4 facilitates the connection of the first copper tube 5c3, so that the first copper tube 5c3 can be placed horizontally inside the water tank 6a. The water tank 6a is controlled by the control device 6b placed inside the computer room body 1, so that the entire computer room body 1 has only one single device, the control device 6b, except for the storage unit 2, thereby freeing up a large amount of space in the computer room body 1 and avoiding the situation where the temperature inside the computer room body 1 increases due to the heat island effect caused by too many devices in the computer room body 1.

[0057] Further, such as Figure 8 As shown:

[0058] Sealing rings 5c5 are provided at the connection positions between the two ends of the first copper tube 5c3 and the first bellows 5c2 and the second bellows 5c4.

[0059] Based on the above embodiments, the technical problem that the present application intends to solve is how to prevent water from entering the first copper tube 5c3 immersed in the water storage tank 6a. To this end, the present application provides a sealing ring 5c5 at the connection position between the first copper tube 5c3, the first corrugated tube 5c2 and the second corrugated tube 5c4 to achieve sealing at the connection position. Threads can be provided at both ends of the first copper tube 5c3 to cooperate with the threads provided at the connection end of the first copper tube 5c3 and the second corrugated tube 5c4 to achieve a tight connection and ensure the strength of the connection.

[0060] Further, such as Fig. 9 and 10 As shown:

[0061] A plurality of openings 1a1 are provided on the floor 1a of the machine room body 1, and the openings 1a1 are provided at the positions where the first bellows 5c2 and the second bellows 5c4 of the heat dissipation unit 5c are connected to the floor 1a. A closing plate 1b is installed at the opening 1a1, and the closing plate 1b closes the opening 1a1. A plurality of sockets 1b1 are provided on the closing plate 1b, and the size and number of the sockets 1b1 are consistent with those of the first bellows 5c2 and the second bellows 5c4 of the heat dissipation unit 5c.

[0062] Based on the above embodiments, the technical problem that the present application intends to solve is how the gas storage box 5c1 and the first bellows 5c2 of the heat dissipation unit 5c pass through the floor 1a of the machine room body 1. To this end, the present application provides a plurality of openings 1a1 on the floor 1a of the machine room body 1 to facilitate the gas storage box 5c1 to enter under the floor 1a, and a closing plate 1b is installed at the opening 1a1. The closing plate 1b can be detachably installed on the opening 1a1 and is provided with jacks 1b1 that match the number and size of the gas storage box 5c1 and the first bellows 5c2, which facilitates the passage of the first bellows 5c2 and the second bellows 5c4 while preventing the liquid in the water tank 6a under the floor 1a from entering the upper layer of the floor 1a through the opening 1a1.

[0063] Further, such as Figure 2 and 9 As shown:

[0064] A support frame 1c is provided at the bottom of the floor 1a of the machine room body 1, and the support frame 1c is used to support the entire floor 1a.

[0065] Based on the above embodiments, the technical problem that the present application intends to solve is how to avoid squeezing the water tank 6a when the water cooling system 6 is arranged at the bottom of the floor 1a. To this end, the present application provides space for the installation of the water tank 6a by installing the floor 1a of the machine room body 1 on the support frame 1c. The support frame 1c can raise the floor 1a, ensure the stability of the floor 1a structure, and facilitate the installation of the water tank 6a, so that the working area inside the machine room body 1 is released, and the area occupied by the equipment in the machine room body 1 is reduced.

[0066] Further, such as Figure 1 and 9 As shown:

[0067] The precision air conditioning system 3 includes a fan 3a installed on the machine room body 1, and the fan 3a is used to transport cooling air into the machine room body 1. A plurality of ventilation fans 1d are arranged on the machine room body 1, and the ventilation fans 1d are used to discharge the internal air of the machine room body 1 to the outside.

[0068] Based on the above embodiments, the technical problem that the present application wants to solve is how the precision air conditioning system 3 adjusts the temperature inside the computer room body 1. To this end, the present application cools down the inside of the computer room body 1 by installing a precision air conditioning system 3 on the computer room body 1. The precision air conditioning system 3 can be one or a combination of water-cooled air conditioning, chilled water air conditioning, air-cooled air conditioning, fresh air air conditioning, energy-saving air conditioning, etc. In this embodiment, an air conditioner of a fresh air system is shown, and its fan 3a is installed on one side of the computer room body 1, and a plurality of ventilation fans 1d are provided on the computer room body 1 to facilitate the circulation of gas. Since part of the heat generated by the storage unit 2 has been processed by the water cooling system 6, the temperature adjustment inside the computer room body 1 is relatively simple, and the power of the fan 3a of the precision air conditioning system 3 is also reduced, solving the problem of high power of the heat dissipation system.

[0069] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
