Description

Technical Field

[0001] This invention mainly relates to a computer room layout structure, specifically, a circulating energy-saving and environmentally friendly computer room. Background Technology

[0002] Computer rooms are spaces on campus where a large number of computers are concentrated, and also areas where a large number of students gather. Therefore, when the computers are running, their cases will emit a lot of heat. Since computer rooms are relatively enclosed spaces, even with windows open for ventilation, heat can easily accumulate indoors. This can not only raise the indoor temperature and cause discomfort to students, but also cause the internal components of the computers to lose heat in time, passively reducing their heat dissipation efficiency and leading to temperature increases, posing a risk of overheating damage.

[0003] Existing computer room cooling systems can largely solve the above problems, but since the computers in the computer room need to be turned on for a long time, the cooling system also needs to run for a long time, which results in a lot of energy consumption. Therefore, how to meet the cooling and heat dissipation needs of computer rooms in an energy-saving and environmentally friendly way is a research direction that should be focused on in this field. Summary of the Invention

[0004] To address the technical deficiencies in the background technology, this invention proposes a circulating energy-saving and environmentally friendly computer room, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A circulating energy-saving and environmentally friendly computer room includes a room body, a non-powered fan installed on the roof of the room body, and a powered fan installed on the roof of the room body and connected to the non-powered fan. The walls of the room body have several rows of longitudinally arranged, inclined rectangular air inlets, with the inclination direction of the air inlets facing away from the powered fan. The air inlets have several elongated grooves evenly distributed on the vertical sidewalls. Water injection holes are provided above the grooves, and receiving grooves flowing towards the inside of the room body are provided below the air inlets. The receiving grooves on the same wall are shielded by a filter strip. A coarse filter screen is provided inside the air inlets. The water injection holes are connected to a water injection pipe network, which is arranged around the upper edge of the room body. The receiving grooves are connected to the inlet of a primary circulating pump, and the outlet of the primary circulating pump is connected to the water injection pipe network.

[0006] As a further technical solution of the present invention, the air inlet has an oblique rectangular profile, all air inlets provided in the room have the same volume, and the inclination direction is away from the nearest power fan, and the number of power fans close to any wall in the room is at least one.

[0007] As a further technical solution of the present invention, the air inlet has an oblique elongated platform-shaped outline, and the volume of all air inlets provided in the room is based on the straight-line distance to the power fan. The closer the distance, the greater the height of the air inlet. The number of power fans close to any wall in the room is at least one.

[0008] As a further technical solution of the present invention, the tank is a fluid-shaped blind hole that is placed horizontally or inclined toward the power fan.

[0009] As a further technical solution of the present invention, the receiving slot is inclined towards the interior of the room, the receiving slots are connected by a guide tube with openings at both ends, the filter strip extends into the openings at both ends of the guide tube, and the openings of the guide tube are inclined upward towards the inner wall of the room so that the two ends of the filter strip protrude out of the guide tube, and the middle section of the guide tube is connected to the primary circulation pump through a pipeline.

[0010] As a further technical solution of the present invention, both ends of the filter strip are provided with elastic connecting buckles, and the filter strip is a soft mesh embedded with activated carbon.

[0011] As a further technical solution of the present invention, the water injection network is also provided with several ports facing the indoor side of the room. The ports are connected to the nearest power fan through radial branching pipes, and then connected to the inlet of a secondary circulation pump through a return pipe. The outlet of the secondary circulation pump is connected to the water injection hole.

[0012] As a further technical solution of the present invention, the branched pipeline includes segmented pipe bodies and two-way connectors or cross connectors connecting the segmented pipe bodies. The middle section of the segmented pipe body has a willow leaf-shaped cross section, and the two ends have circular cross sections. The outer tip of the segmented pipe body faces the power fan.

[0013] The beneficial effects of this invention are as follows: while utilizing the computer's self-heating and water cooling to form an internal air circulation flow to assist heat dissipation in the computer room, it also uses a combination of non-powered fans and powered fans to bring fresh outdoor air into the room, promoting the circulation of indoor and outdoor air. Water cooling is used to assist in cooling, and water is used for cleaning the filtration structure and water circulation, thereby achieving a circulating energy-saving and environmentally friendly computer room layout with low energy consumption, which is convenient and effective.

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0021] To address the technical deficiencies in the background technology, this invention proposes a circulating energy-saving and environmentally friendly computer room, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0022] Combination Figures 1 to 5 As shown, a circulating energy-saving and environmentally friendly computer room includes a room body 1, a non-powered fan 2 installed on the outer roof of the room body 1, and a powered fan 3 installed on the inner roof of the room body 1 and connected to the non-powered fan 2. The walls of the room body 1 have several rows of longitudinally arranged, inclined rectangular air inlets 4, with the inclination direction of the air inlets 4 facing away from the powered fan 3. The air inlets 4 have several elongated grooves 5 evenly distributed on their vertical sidewalls. A water injection hole 6 is provided above the tank body 5, and a receiving trough 7 flowing to the inside of the room body 1 is provided below the air inlet 4. The receiving trough 7 on the same wall is shielded by a filter strip 8. A coarse filter screen 9 is provided inside the air inlet 4. The water injection hole 6 is connected to a water injection pipe network 10. The water injection pipe network 10 is arranged around the upper edge of the room body 1. The receiving trough 7 is connected to the water inlet of the primary circulation pump 11. The water outlet of the primary circulation pump 11 is connected to the water injection pipe network 10.

[0023] The basic principle of this invention is as follows:

[0024] Under normal circumstances, the room 1 uses a non-powered fan 2 installed outside the roof to achieve indoor heat dissipation and ventilation without energy consumption. At the same time, the air inlet 4 can also work with the non-powered fan 2 to allow outdoor air to continuously enter the room and carry away the heat of the equipment in the room 1. This is usually used when the equipment load in the computer room is small or under normal load. At this time, no energy is consumed to drive the above structure to dissipate heat. The indoor and outdoor air also form a large circulation, ensuring that the temperature difference between indoor and outdoor is not too large, allowing the cooler outdoor air to enter the room and carry away the heat.

[0025] Combination Figures 1 to 3 As shown, under medium or high load conditions, the temperature accumulation of the equipment inside room 1 will exceed the range that the non-powered fan 2 can withstand. At this time, it is necessary to turn on the powered fan 3 to assist in transporting the heat in the room along the location of the non-powered fan 2, allowing the heat to be sent away from the top of the room 1. At the same time, it will also accelerate the entry of outdoor air into the room 1 through the air inlet 4. The part framed by the dotted line on the right side of the figure is a simplified illustration, which is consistent with the left side to avoid the difficulty of identification due to too many lines in the figure. This forms a rapid circulation of indoor and outdoor air temperature exchange. Since heat accumulates upward, the extraction of the powered fan 3 conforms to the trend of heat flow, and can drive the heat outward with less energy. At this time, the air inlet 4 is a rectangular opening with a sloping path. This allows the air perpendicular to the intake side and the exhaust side of the air inlet 4 to form a certain degree of Bernoulli effect due to the narrow flow at the position where the straight distance between the two sides is the smallest, which accelerates the flow of air and promotes the heat discharge of the powered fan 3 from another direction. In this way, heat can be discharged under the premise of energy saving, which is very convenient.

[0026] Combination Figures 1 to 3 As shown, under high load conditions, increasing the output of the power fan 3 to dissipate heat is obviously less efficient than using the electrical energy consumed to drive the power fan 3. Therefore, a water circulation system is created by driving the water injection network 10, the primary circulation pump 11, the water injection hole 6, and the receiving tank 7. The thick solid lines in the diagram represent buried or exposed connecting pipes. To minimize water waste, external water supply to this circulation system is generally not continuously activated. Furthermore, the water injection network 10 is laid around the upper edge of the housing 1. When water with a temperature significantly lower than the indoor temperature is introduced into the water injection network 10, a ring-shaped low-temperature zone will be formed in the upper part of the room 1. This low-temperature zone will form a convection with the heat radiating upward from the room, thereby generating wind. This will then form a circular, scattered vortex within the room 1. These vortices will flow along the air outlet side of the air inlet 4, thereby accelerating the entry of outdoor air into the room. Finally, the air will be discharged outward from the non-powered fan 2 by the action of the powered fan 3, thus ensuring the maintenance of the indoor temperature under high load conditions.

[0027] In the above structure, the air inlet 4, through the inclusion of a trough 5, allows the air, which has not been accelerated by the Bernoulli effect at the point where the straight-line distance between the inlet and outlet sides of the air inlet 4 is minimal, to form turbulence at the trough 5. This turbulence obstructs suspended particles in the air as they collide with the trough 5. At this time, a continuous flow of circulating water is delivered from the water inlet 6, which can effectively and promptly cool the air upon contact with the water, while also purifying some of the suspended particles in the air. This prevents the air delivered into the room 1 from becoming excessively turbid and hot, thus contributing to the cooling of the indoor temperature. Furthermore, because the air inlet 4 is positioned away from the direction of the power fan 3, it is easier to ensure the occurrence of the Bernoulli effect's narrow flow phenomenon, while also allowing the air more opportunities to contact the trough 5 for purification and cooling. This achieves two goals at once, resulting in energy conservation and environmental protection.

[0028] Combination Figure 1 and Figure 5 As shown, after the water containing some air particles flows into the receiving tank 7 along the height direction of the air inlet 4, it will be simply filtered by the filter strip 8, thereby improving the reuse efficiency of the water, minimizing the need for water replenishment, and reducing water consumption. The filter strip 8 can also be easily disassembled and replaced for low-cost maintenance, simplifying the cost of daily maintenance.

[0029] Reference Figure 3 As shown, in one preferred embodiment of the present invention, the air inlet 4 has an oblique rectangular profile, all air inlets 4 provided in the room have the same volume, and the inclination direction is away from the nearest power fan 3. The number of power fans 3 near any wall inside the room 1 is at least one.

[0030] With the above setup, the number of power fans 3 can ensure that each wall with an air inlet 4 can achieve good ventilation efficiency. Since the air inlet 4 has a rectangular outline and the area of ​​the air inlet side is the same as that of the air outlet side, the narrow flow effect needs to be linearly amplified by increasing the number of air inlets 4 in order to achieve a better indoor-outdoor circulation effect. This also makes it easier to set up the layout of the air inlets 4.

[0031] Reference Figure 4 As shown, in one of the preferred embodiments of the present invention, the air inlet 4 has a sloping elongated platform-shaped outline. The volume of all the air inlets 4 provided in the room body 1 is based on the straight-line distance to the power fan 3. The closer the distance, the greater the height of the air inlet 4. The number of power fans 3 close to any wall inside the room body 1 is at least one.

[0032] In the above-described configuration, since the air inlet 4 has become a slanted elongated platform shape, the areas of the air inlet side and the air outlet side of the air inlet 4 are not the same. Combined with the narrow flow effect under the Bernoulli phenomenon of the original structure, it is actually equivalent to reducing the passage area under the minimum straight-line distance between the two, increasing the air velocity, and at the same time, the turbulence phenomenon is also intensified, affecting the efficiency of air cooling and purification, making it higher. The overall efficiency of fresh air passage is theoretically similar to or only slightly different from the previous embodiment. The advantage is that it saves the manufacturing cost of opening the air inlet 4. Therefore, it is not necessary to make each air inlet 4 the same size. It is only necessary to keep the air inlet 4 closest to the power fan 3 at its maximum size, while the air inlet 4 furthest away does not need to be the same size to achieve a similar degree of air circulation effect as in the previous embodiment.

[0033] In one preferred embodiment of the present invention, the tank 5 is a fluid-shaped blind hole placed horizontally or inclined toward the power fan 3. The fluid-shaped blind hole refers to a contour similar to a water droplet or an airfoil cross section, which allows the air to come into more full contact with the inner wall of the tank 5, generating turbulence and making it more likely that airborne particles will combine with the water flow from the water injection hole 6. The water flow from the water injection hole 6 can also more easily cover the entire tank 5, ensuring more thorough purification and cooling.

[0034] Reference Figure 1 As shown, in one preferred embodiment of the present invention, the receiving slot 7 is inclined toward the interior of the room 1, and the receiving slots 7 are connected by a guide pipe 12 with openings at both ends. The filter strip 8 extends into the guide pipe 12 from the openings at both ends, and the opening of the guide pipe 12 is inclined upward toward the inner wall of the room 1, so that the two ends of the filter strip 8 protrude from the guide pipe 12. The middle section of the guide pipe 12 is connected to the primary circulation pump 11 through a pipeline.

[0035] The above-described structure makes it easier to replace the filter strip 8. Simply connect one end of the new filter strip 8 to one end of the old filter strip 8, and pull the other end of the old filter strip 8 to send the new filter strip 8 into the guide pipe 12. The guide pipe 12 can prevent water from splashing out of the receiving tank 7 and wetting the floor of the chamber 1. The receiving tank 7 can also be placed at an angle to make it easier for the water to converge and flow along the middle section of the guide pipe 12 to the first-stage circulation pump 11 to complete the water circulation.

[0036] In one preferred embodiment of the present invention, both ends of the filter strip 8 are provided with elastic connecting buckles 13, and the filter strip 8 is a soft mesh embedded with activated carbon.

[0037] The above-described structure allows the filter strip 8 to perform a good filtration function without increasing maintenance costs. At the same time, the flexible connecting buckle 13 makes it easier to position both ends of the filter strip 8, preventing it from shifting left and right in the guide tube 12. The connecting buckle 13 can also be used to connect the old and new filter strips 8 for easy replacement. The soft mesh activated carbon content structure makes it easy to install and remove and to perform a certain degree of filtration without increasing costs excessively. Since the working environment of this application has very low filtration pressure, theoretically, the filter strip 8 should only be replaced once every long period of time, which is very economical and environmentally friendly.

[0038] Reference Figure 1 As shown, in one preferred embodiment of the present invention, the water injection network 10 is further provided with a plurality of ports 100 facing the indoor side of the room. The ports 100 converge to the bottom of the nearest power fan 3 through radial branching pipes 14, and are connected to the inlet end of a secondary circulation pump 16 through a return pipe 15. The outlet end of the secondary circulation pump 16 is connected to the water injection hole 6.

[0039] By using the branch pipe 14, the water circulating above the chamber 1 can be circulated as close as possible to the power fan 3. This also facilitates heat exchange between the hot water and the cold water in the water injection network 10 when the hot water flows to the power fan 3. The secondary circulation pump 16 is set to avoid the problem of slow water flow caused by excessive load on the primary circulation pump 11. Preferably, one is set above the chamber 1 and the other is set below the chamber 1.

[0040] Reference Figure 5 As shown, as a further technical solution of the present invention, the branch pipe 14 includes a segmented pipe body 140 and a two-way connector 141 or a cross connector 142 connecting the segments of the pipe body 140. The middle section of the segmented pipe body 140 has a willow leaf-shaped cross section and the two ends have circular cross sections, and the outer tip of the segmented pipe body 141 faces the power fan 3.

[0041] The above-described structure allows the branched pipes 14 to form a spider web-like structure, and the willow-leaf-shaped cross-section increases the area for heat exchange with the air. The segmented pipe 140 is preferably made of a heat-conducting metal. At the same time, in order to better replace the segmented pipe 140 without affecting the overall water flow performance, the two-way connector 141 and the cross connector 142 can be used to replace a certain segmented pipe 140 by simply cutting off the connecting connectors, without affecting the water flow of other segmented pipes 140, which is very convenient.

[0042] The beneficial effects of this invention are as follows: while utilizing the computer's self-heating and water cooling to form an internal air circulation flow to assist heat dissipation in the computer room, it also uses a combination of non-powered fans and powered fans to bring fresh outdoor air into the room, promoting the circulation of indoor and outdoor air. Water cooling is used to assist in cooling, and water is used for cleaning the filtration structure and water circulation, thereby achieving a circulating energy-saving and environmentally friendly computer room layout with low energy consumption, which is convenient and effective.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
