[0035] DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0038] In order to solve the above problems, the researchers will improve the structure of the machine room in which the above devices are stored during the design process, that is, by setting the air inlet and air outlet on the wall of the machine room, the circulation of indoor and outdoor air is driven by the fan, so as to realize the purpose of cooling indoor air by outdoor air. However, this heat dissipation method is easy to cause the outdoor humid air to enter the indoor, which will affect the service life of the equipment due to the influence of the humid air on the internal electrical structure of the equipment.

[0039] In summary, in order to avoid the influence of outdoor humid air on the working equipment, a machine room heat dissipation system and a machine room are provided in the present application, a water well is arranged outside the machine room, and a drying pipe is also arranged outside the machine room, the air inlet of the drying pipe is communicated with the outdoor, and the air outlet of the drying pipe is communicated with the inside of the machine room, so as to cool and dry the outdoor air by the drying pipe to dissipate heat for the working equipment inside the machine room, thereby realizing effective protection of the working equipment, and further improving the working stability of the working equipment.

[0040] The present application will be described below in combination with the drawings and specific examples.

[0041] Embodiment one

[0042] Please combine Figures 1 to 3The first aspect of the present application provides a machine room heat dissipation system 100, which comprises a water source 1, a drying pipe 2 and an air outlet fan 31. The water source 1 is arranged outside the machine room, and the drying pipe 2 is also arranged outside the machine room. The working equipment is placed inside the machine room, and the drying pipe 2 comprises an air inlet 21, an air outlet 22 and a heat exchange pipe 23 arranged between the air inlet 21 and the air outlet 22. The air inlet 21 of the drying pipe 2 is communicated with the outdoor, and the air outlet 22 is communicated with the inside of the machine room, so that the outdoor air can be transmitted to the inside of the machine room through the drying pipe 2. The air outlet fan 31 sends the high-temperature air inside the machine room to the outdoor to realize the air circulation between the inside of the machine room and the outside. At the same time, the upper water pipe 24 and the lower water pipe 25 are respectively connected to the two ends of the heat exchange pipe 23. The upper water pipe 24 is connected to the water pump 26 and extends to the water surface, so that the water in the water source 1 is pumped into the heat exchange pipe 23 through the upper water pipe 24 by the water pump 26, so that the heat exchange pipe 23 is filled with well water with lower temperature. When the outdoor air passes through the heat exchange pipe 23, it can be cooled by the heat exchange pipe 23 with lower temperature, so as to realize the cooling of the outdoor air. At the same time, the water vapor in the outdoor air can condense on the heat exchange pipe 23 when it is cooled, so that the air entering the machine room through the heat exchange pipe 23 is low-temperature and dry, so as to improve the cooling and moisture-proof protection of the working equipment in the machine room, and improve the working stability of the working equipment.

[0043] In an example, the water source 1 can be a water storage tank opened in the outdoor. Since the water temperature in the water storage tank is usually lower than the temperature in the outdoor air, the water in the water storage tank can be used for drying and cooling. Or in other examples, the water source 1 can also be a water tank with good heat preservation, and the water in the water tank is cold water to realize the drying and cooling of the outdoor air.

[0044] In another example, the above-mentioned water source 1 can be a water well. Since the water temperature in the water well can maintain a relatively stable temperature in the natural state, it is not easily affected by the environmental temperature. Therefore, when the outdoor temperature is high, the water well water temperature can be used to cool the outdoor air. At the same time, since the water in the water well is used to cool the outdoor air, it does not need additional condensers, condensate and other equipment, and it can realize the cooling of the outdoor air under the premise of saving energy resources. In addition, the use of cold water to condense the water vapor in the outdoor air for drying also does not need to consume additional electricity, drying materials and other resources, and the cooling and drying process is more energy-saving and environmentally friendly. Please combine Figure 2 、 Figure 4Further, the bottom of the drying pipe 2 is further provided with a water outlet 27, when the heat exchange pipe 23 dries the outdoor air, the water droplets condensed on the heat exchange pipe 23 can slide downward under the action of gravity, so as to be discharged to the water source 1 through the water outlet 27 of the drying pipe 2, so that the water droplets on the heat exchange pipe 23 can be discharged in time. At the same time, because the water vapor in the outdoor air may contain some impurities, in order to avoid polluting the water in the water source 1, the water filter structure 28 is further arranged at the water outlet 27, so that the water filter structure 28 can be used to filter the water droplets in the drying pipe 2 before being discharged to the water source 1, so as to protect the water quality in the water source 1.

[0045] Specifically, the above-mentioned water filter structure 28 includes a water filter net 281 and an activated carbon filter net 282, the water filter net 281 is arranged on the upper layer of the activated carbon filter net 282, so as to realize the preliminary filtration of the water droplets, and then the second filtration is realized through the activated carbon filter net 282, so that the water discharged to the water source 1 can be fully filtered, thereby effectively protecting the water source 1.

[0046] It can be understood that in other embodiments, the above-mentioned water filter structure 28 can also be provided with only the water filter net 281, and the water filter net 281 can be single-layer or multi-layer; or only the activated carbon filter net 282 is provided; or the water filter net 281 is arranged on the upper and lower layers of the activated carbon filter net 282, and the filtering effect of the lower water filter net 281 is better than that of the upper water filter net 281, etc. In the present embodiment, the specific arrangement mode of the water filter structure 28 is not limited.

[0047] In one of the embodiments, the computer room heat dissipation system 100 further includes a partition plate 41, an evaporator 42 and a supply fan 43, the partition plate 41 is arranged in the interior of the computer room, so as to divide the interior space of the computer room into a first space and a second space, the working equipment is arranged in the first space, the evaporator 42 is arranged in the second space, the air outlet 22 of the drying pipe 2 is communicated with the second space, and the outdoor air can enter the second space of the computer room through the drying pipe 2, at this time, the evaporator 42 arranged in the second space can dry the air from the drying pipe 2, and the supply fan 43 arranged on the partition plate 41 sends the air in the second space into the first space. As shown in Figure 2 Figure 2 ​The dashed arrow in the figure represents the direction of air flow. By setting the partition 41 and the evaporator 42 in the machine room, on the one hand, when the outdoor air is dried by the drying pipe 2, the humidity is still high, at this time, the evaporator 42 can be used to further dry the air from the drying pipe 2, if the humidity has reached the standard, the evaporator 42 does not need to be started; on the other hand, when the outdoor air passes through the drying pipe 2 without starting the water pump 26 (i.e. the drying pipe 2 does not dry and cool the outdoor air), the evaporator 42 can be used to dry the outdoor air from the drying pipe 2; the air supply fan 43 can send the air meeting the humidity requirement into the first space, thereby effectively reducing the moisture entering the first space, and effectively protecting the working equipment in the first space.

[0048] As shown in the figure, Figure 2 The first space and the second space can be arranged vertically, and the second space can be arranged at the lower part of the first space, so that the gas with lower temperature and dryness can sufficiently cool the working equipment during the upward movement. In other examples, the first space and the second space can also be arranged horizontally, which can be adjusted according to the actual situation, and the arrangement of the first space and the second space is not limited in the embodiment.

[0049] It is worth noting that the partition 41 can separate the internal space of the machine room into the first space and the second space, at this time, the partition 41 is sealingly connected to the internal space of the machine room, thereby achieving the division of the first space and the second space. The partition 41 can be a plate made of the same material as the machine room, for example, if the machine room is made of metal material, the partition 41 can also be made of the same metal material, or if the machine room is made of cement building, the partition 41 can also be a cement plate, so as to facilitate the overall design and construction of the partition 41 and the machine room; or the partition 41 can be made of different materials from the machine room, for example, if the machine room is made of cement building, the partition 41 can be a sealingly connected metal plate, which can reduce the cost while achieving the separation of the first space and the second space. In actual design, it can be adjusted as needed, and the material of the partition 41 is not limited in the embodiment.

[0050] Specifically, the machine room heat dissipation system 100 further comprises an outdoor unit 44, which is arranged outside the machine room, and the outdoor unit 44 is connected to the evaporator 42, so that the working heat generated by the evaporator 42 during operation can be dissipated to the outside through the outdoor unit 44, thereby avoiding affecting the temperature inside the machine room.

[0051] Further, in order to effectively protect the working equipment and save energy, the machine room heat dissipation system 100 further comprises a detection assembly and a control module 6, so as to determine whether the water pump 26 needs to work through the cooperation of the detection assembly and the control module 6, thereby effectively achieving the heat dissipation and drying of the machine room heat dissipation system 100.

[0052] Specifically, the detection assembly comprises a water well temperature sensor 51 and an outdoor temperature sensor 52, the water well temperature sensor 51 is arranged in the water source 1 for detecting the water temperature in the water source 1, the outdoor temperature sensor 52 is arranged outside the air inlet 21 of the drying pipe 2 for detecting the outdoor temperature, and the water well temperature sensor 51 and the outdoor temperature sensor 52 are electrically connected to the control module 6 at the same time. The control module 6 can monitor and compare the outdoor temperature and the water temperature of the water source 1 in real time, when the outdoor temperature is higher than the water temperature of the water source 1, the control module 6 controls the water pump 26 to open, so that the water in the water source 1 enters the heat exchange pipe 23. At this time, the outdoor temperature is relatively high, that is, the temperature of the outdoor air is relatively high, which cannot effectively realize the cooling of the working equipment, so the heat exchange pipe 23 needs to realize the cooling and drying of the outdoor air, so that the air entering the machine room can realize the cooling protection of the working equipment; when the outdoor temperature is lower than the water temperature of the water source 1, the control module 6 controls the water pump 26 to close, at this time, the temperature of the outdoor air is low, and it is not necessary to cool it to realize the cooling protection of the working equipment in the machine room, and closing the water pump 26 in time can also save energy, so as to realize the rational use of energy.

[0053] It is worth noting that when the water source 1 is a water well, the water temperature of the water well is in a stable range all year round, that is, it is about 4 degrees Celsius all year round, so in summer, the water well temperature is usually lower than the outdoor temperature, so the water temperature in the water well can be used to cool and dry the outdoor air; in winter, the water well temperature may be higher than the outdoor temperature, at this time, it indicates that the outdoor temperature is low enough to be used for cooling protection of the working equipment, so it is not necessary to cool it.

[0054] It can be understood that the control module 6 can be a single-chip microcomputer, a program in a computer, or an intelligent touch panel, and the control module 6 can be arranged indoors of the machine room, or arranged outdoors of the machine room, or arranged in other positions, as long as it can be electrically connected with each component, and the arrangement of the control module is not limited in the embodiment.

[0055] In one of the embodiments, in addition to the operation of the water pump 26 consuming energy, the operation of the evaporator 42 also consumes energy, in order to further protect the energy, the detection assembly further comprises an intermediate humidity sensor 53, the intermediate humidity sensor 53 and the evaporator 42 are electrically connected to the control module 6, so that the control module 6 can control whether the evaporator 42 needs to work according to the detection result of the intermediate humidity sensor 53, to realize the effective protection of the energy.

[0056] Specifically, the intermediate humidity sensor 53 is arranged at the air outlet 22 of the drying pipe 2, for detecting the air humidity of the outdoor air after passing through the drying pipe 2, at this time the control module 6 can realize monitoring the air humidity of the air from the air outlet 22 of the drying pipe 2, when finding that the air humidity of the air outlet 22 of the drying pipe 2 is greater than the preset threshold value, the control module 6 controls the evaporator 42 to open, so as to dry the air from the air outlet 22 of the drying pipe 2, so that the air entering the first space is dry, thereby realizing effective protection of the working equipment.

[0057] When the outdoor air is dried and cooled by the drying pipe 2, it is possible that the drying pipe 2 cannot completely dry the outdoor air, at this time the arrangement of the intermediate humidity sensor 53 can cooperate with the control module 6 to control the evaporator 42 to open, so as to further dry the outdoor air, so as to avoid the air not meeting the humidity condition from entering the first space, thereby effectively realizing protection of the working equipment; if the air humidity of the outdoor air dried by the drying pipe 2 has met the condition, the control module 6 controls the evaporator 42 to close, thereby avoiding wasting energy. At the same time, since the drying and cooling of the outdoor air by the drying pipe 2 need to be performed under the condition that the water pump 26 is opened, as known from the above description, when the outdoor temperature is lower than the water temperature of the water source 1, the control module 6 controls the water pump 26 to close, at this time the drying pipe 2 only functions as an air duct and cannot dry the outdoor air, at this time the intermediate humidity sensor 53 can be used to determine whether the humidity of the outdoor air meets the requirement, if the humidity of the outdoor air is too high, the evaporator 42 can be opened to dry the outdoor air, so as to realize effective protection of the working equipment; if the air humidity of the outdoor air has met the standard, the evaporator 42 does not need to perform the drying work, thereby avoiding wasting energy.

[0058] It can be understood that when the preset threshold value is less than 35%, the intermediate humidity sensor 53 detects that the air humidity of the air outlet 22 is 30%, at this time the air humidity meets the humidity condition, i.e. meets the standard; if the intermediate humidity sensor 53 detects that the air humidity of the air outlet 22 is 60%, it does not meet the condition, i.e. does not meet the standard. The specific requirement of the preset threshold value can be adjusted according to the working requirement of different working equipment, which is not limited in the embodiment.

[0059] Further, in order to avoid the humid air from entering the first space as much as possible, the drying material 29 is arranged at the air outlet 22 of the drying pipe 2, for drying the air passing through the air outlet 22. That is, when the water pump 26 is running, the arrangement of the drying material 29 at the air outlet 22 of the drying pipe 2 can realize secondary drying of the outdoor air by the drying pipe 2; when the water pump 26 is closed, the drying material 29 arranged at the air outlet 22 of the drying pipe 2 can realize primary drying of the outdoor air, thereby effectively reducing the air humidity.

[0060] Specifically, the dry material 29 can be quicklime dry material 29, silica gel dry material 29, active mineral dry material 29, and montmorillonite dry material 29, etc., wherein the active mineral dry material 29 and the montmorillonite dry material 29 are non-toxic, harmless, green and environmentally friendly, and can avoid pollution to the water in the water source 1. It can be understood that in other embodiments, the dry material 29 can also be other materials, which are not limited in the present embodiment.

[0061] In one embodiment, in order to purify the outdoor air, the machine room heat dissipation system 100 further comprises an air filter screen 71, which is arranged at the connection between the air outlet 22 of the drying pipe 2 and the second space, so that when the outdoor air has entered the drying pipe 2 and enters the second space through the air outlet 22, the air filter screen 71 can filter out dust, leaf fragments, paper or plastic fragments, etc. in the air, so as to avoid the impurities in the outdoor air affecting the working equipment in the machine room, thereby achieving comprehensive protection of the working equipment.

[0062] Please refer to Figure 5 , Figure 6 , further, the machine room heat dissipation system 100 further comprises a rotating disc 72 and a switching motor 73, the switching motor 73 is connected to the rotating disc 72 for driving the rotating disc 72 to rotate. The rotating disc 72 is connected to the outside of the machine room, and the rotating disc 72 has a blocking part 721 for blocking the air outlet 22 of the drying pipe 2 to prevent outdoor air from entering the indoor when needed, i.e. when outdoor air is not needed for heat dissipation and cooling, the blocking part 721 can be a blocking plate, a blocking block, etc. which can block the air outlet 22 of the drying pipe 2 to achieve the structure of blocking the machine room from the outdoor, which is not limited in the present embodiment.

[0063] At the same time, since the air filter screen 71 is a consumable that needs to be replaced regularly, in order to facilitate the switching of the air filter screen 71, the rotating disc 72 further has a plurality of air permeable parts 722, at least two air permeable parts 722 are arranged at intervals, i.e. when the air permeable part 722 is two, the two air permeable parts 722 are arranged at intervals, and when the air permeable part 722 is three or more, each air permeable part 722 is arranged at intervals, and each air permeable part 722 is provided with an air filter screen 71. When it is necessary to replace the air filter screen 71 currently arranged at the air outlet 22, the switching motor 73 can be started to drive the rotating disc 72 to rotate to the position of the next air filter screen 71, so that the new air filter screen 71 can be switched to the air outlet 22. At this time, the air filter screen 71 that has been rotated away from the air outlet 22 can also be replaced, thereby facilitating the disassembly and replacement of the air filter screen 71 for maintenance by the operator.

[0064] Specifically, the air-permeable part 722 can be an opening provided on the rotating disc 72, which can be one large opening corresponding to one air filter screen 71, or multiple small openings corresponding to one air filter screen 71, and the position of the rotating disc 72 itself without the air-permeable part 722 can form the blocking part 721. When there are two air-permeable parts 722, the two air-permeable parts 722 can be arranged at 180 degrees with the center of rotation of the rotating disc 72 as the center, so that the distance between the two air filter screens 71 is the largest, which can more conveniently realize the disassembly and replacement of the air filter screen 71 that needs to be disassembled. At the same time, when the rotating disc 72 is rotated by 90 degrees, it can be rotated to the blocking part 721, that is, it can also facilitate the switching between the blocking part 721 and the air-permeable part 722. It can be understood that in other examples, the number and arrangement of the air-permeable part 722 can be adjusted according to actual conditions, which is not limited in the embodiment.

[0065] In one embodiment, the machine room heat dissipation system 100 further comprises an internal circulation pipeline 8, both ends of the internal circulation pipeline 8 are communicated with the first space and the second space, and the internal circulation pipeline 8 is provided with an air lock 81 at one end of the first space, and the top of the air outlet fan 31 is further provided with a rotating cover plate 32, Figure 2 When the rotating cover plate 32 is opened, the air duct of the air outlet fan 31 is opened, and at this time the air outlet fan 31 can exhaust the indoor air of the machine room to the outdoor, Figure 3 When the rotating cover plate 32 is closed, the air duct of the air outlet fan 31 is closed, and at this time the air outlet fan 31 cannot exhaust the indoor air of the machine room to the outdoor. The control module 6 is electrically connected to the switching motor 73, and when the machine room needs internal circulation, the control module 6 controls the switching motor 73 to drive the rotating disc 72 to rotate to the blocking part 721, and opens the evaporator 42, the air lock 81 and the air supply fan 43, and rotates the rotating cover plate 32 to close the air duct of the air outlet fan 31.

[0069] Specifically, when the partition 41 is arranged in the machine room, the bearing plate 9 can be arranged above the partition 41, i.e. the bearing plate 9 is arranged in the first space and divides the first space into two parts, so that the air with lower temperature and dryness from the second space first enters the lower part of the bearing plate 9 when entering the first space, and then is sent to the upper part of the bearing plate 9 by the upper air passage 91, thereby effectively achieving the cooling protection of the working equipment.

[0070] Embodiment two

[0071] Please refer to Figure 7 The second aspect of the present application provides a machine room 200, which comprises a machine room body 210 and the machine room heat dissipation system 100 as described in the first aspect above, and the working equipment 300 is placed inside the machine room body 210, the water source 1 and the drying pipe 2 of the machine room heat dissipation system 100 are arranged outside the machine room 200, the air inlet 21 of the drying pipe 2 is communicated with the outdoor, and the air outlet 22 is communicated with the inside of the machine room 200, so that the outdoor air can be transmitted to the inside of the machine room 200 through the drying pipe 2, and the high-temperature air in the machine room 200 is sent to the outdoor by the air outlet fan 31, so as to realize the air circulation between the inside of the machine room 200 and the outside. At the same time, the two ends of the heat exchange pipe 23 are respectively connected with the upper water pipe 24 and the lower water pipe 25, the upper water pipe 24 is connected with the water pump 26 and extends to the water surface, so as to pump the water in the water source 1 into the heat exchange pipe 23 through the upper water pipe 24 by the water pump 26, so that the heat exchange pipe 23 is filled with well water with lower temperature, so that when the outdoor air passes through the heat exchange pipe 23, it can be cooled by the heat exchange pipe 23 with lower temperature, so as to realize the cooling of the outdoor air, and at the same time, the moisture in the outdoor air can be condensed on the heat exchange pipe 23, so that the air entering the machine room 200 through the heat exchange pipe 23 is low-temperature and dry, so as to improve the cooling and moisture-proof protection of the working equipment 300 in the machine room 200, and improve the working stability of the working equipment 300.

[0072] The machine room 200 can realize various heat dissipation modes, in one example, when the outdoor temperature is higher than the water temperature of the water source 1, the water pump 26 is started by the control module 6, so that the water in the water source 1 enters the heat exchange pipe 23. At this time, the outdoor temperature is high, i.e. the temperature of the outdoor air is high, which cannot effectively realize the cooling of the working equipment 300, so the heat exchange pipe 23 needs to cool and dry the outdoor air, so that the air entering the machine room 200 can realize the cooling protection of the working equipment 300; when the outdoor temperature is lower than the water temperature of the water source 1, the water pump 26 is closed by the control module 6, at this time, the temperature of the outdoor air is low, and it does not need to be cooled to realize the cooling protection of the working equipment 300 in the machine room 200, and at the same time, the timely closing of the water pump 26 can save energy, so as to realize the reasonable use of energy.

[0073] In another example, when the outdoor temperature is lower than the water temperature of the water source 1, the control module 6 controls the water pump 26 to be closed, at this time, the drying pipe 2 only functions as an air duct, and cannot dry the outdoor air, at this time, the humidity of the outdoor air can be determined by the intermediate humidity sensor 53, if the humidity of the outdoor air is too high, the evaporator 42 can be started to dry the outdoor air, so as to effectively protect the working equipment 300; if the humidity of the outdoor air has reached the standard, the evaporator 42 does not need to work, so as to avoid wasting energy.

[0074] In another example, when the indoor and outdoor temperatures meet certain conditions, indoor circulation can be performed, for example, when the indoor temperature is lower than the outdoor temperature, indoor self-circulation can be performed; or when the indoor temperature is lower than a certain value, indoor self-circulation can be performed, and when the indoor temperature is higher than the value, indoor and outdoor circulation can be performed.

[0075] In addition, the partition plate 41 is arranged in the machine room 200 to divide the internal space of the machine room 200 into the first space 21a and the second space 21b, the working equipment 300 is arranged in the first space 21a, the evaporator 42 is arranged in the second space 21b, the air outlet 22 of the drying pipe 2 is communicated with the second space 21b, and the outdoor air can enter the second space 21b of the machine room 200 through the drying pipe 2, at this time, the evaporator 42 arranged in the second space 21b can dry the air from the drying pipe 2, and the air supply fan 43 arranged on the partition plate 41 sends the air in the second space 21b into the first space 21a. At this time, by arranging the partition plate 41 and the evaporator 42 in the machine room 200, on the one hand, when the outdoor air is dried through the drying pipe 2, the humidity is still high, at this time, the evaporator 42 can be used to further dry the air from the drying pipe 2, if the humidity has reached the standard, the evaporator 42 does not need to be started; on the other hand, when the outdoor air passes through the drying pipe 2 without starting the water pump 26 (that is, the drying pipe 2 does not dry and cool the outdoor air), the evaporator 42 can be used to dry the outdoor air from the drying pipe 2; the air supply fan 43 can send the air meeting the humidity requirement into the first space 21a, so as to effectively reduce the moisture entering the first space 21a, and effectively protect the working equipment 300 in the first space 21a.

[0076] It is worth noting that the working equipment 300 described above can be a cabinet server, a blade server, a storage hard disk cabinet, or a storage with a support frame, and the like, and is not limited in the embodiment.

[0077] It can be understood that the machine room 200 can adjust the ventilation and heat dissipation mode according to the demand of the working equipment 300 and the outdoor environmental condition, and in the embodiment, the above example is given, and in other embodiments, heat dissipation can also be performed through other control modes, which is not limited in the embodiment.
