Description

Technical Field

[0001] The utility model belongs to the technical field of data centers, and in particular relates to a temperature and humidity preprocessing device based on a fresh air system of a data center. Background Art

[0002] Changes in temperature and humidity have a significant impact on the product performance of data centers. Creating an environment with suitable and constant temperature and humidity is very necessary for the smooth operation of data centers.

[0003] Regarding the impact of temperature on data center equipment, if the temperature is too high and cannot be dissipated in time, the internal IC devices will form crystals, affecting the normal operation of electronic components and reducing system stability. When the temperature is too low, the resistance of the hardware will increase, causing the aging of electronic components to accelerate and even possibly damaging the hardware. At the same time, at low temperatures, the insulating material will become hard and brittle, which will also weaken the structural strength. In addition, for bearings and mechanical transmission parts, the lubricating oil they carry will condense due to cold, and the viscosity will increase, resulting in stickiness. In addition, when the temperature is too low, the flux with a high tin content will disintegrate, thereby reducing the strength of the electrical connection, and even causing faults such as desoldering and short circuits.

[0004] Regarding the impact of humidity on data center equipment, when the relative humidity of the air is too high, a layer of water film is easily formed on the surface of IT equipment or electronic components, with a thickness generally between 0.001-0.01μm and 10μm. The formation of water film may cause "conductive paths" or arcing, leading to failures. IT equipment is composed of many chips and components, which are very sensitive to static electricity. When the air humidity in the computer room is too low, a relatively dry environment will be formed. In this environment, the activities of the staff are very likely to generate static voltage, thereby damaging the equipment.

[0005] In order to purify and ventilate the indoor air, the data center is equipped with a fresh air system to introduce outside air into the data center. However, the outdoor air has different temperatures and humidity compared to the air inside the data center. If it is directly filtered through the fresh air system and sent into the data center, it will cause significant changes in the temperature and humidity inside the data center. The equipment in the data center cannot operate in an environment with suitable and constant temperature and humidity, which can easily lead to various failures due to temperature and humidity changes.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figures 1 to 4 As shown, in an illustrative embodiment of the temperature and humidity pretreatment device based on the fresh air system of a data center of the utility model, the temperature and humidity pretreatment device based on the fresh air system of a data center includes a fresh air box body 1 and a heat exchange core body 2.

[0035] The fresh air box body 1 has two, which are respectively connected to the front end and the rear end of the heat exchange core 2. The heat exchange core 2 has multiple air flow channels 21. The air flow passes through the two ends and respectively connects the two fresh air boxes 1, so that the two fresh air boxes 1 are connected through the heat exchange core 2.

[0036] The fresh air box 1 is provided with a fresh air inlet 11, which is located on the side of the fresh air box 1 away from the heat exchange core 2. A wet film 3 and a water supply pipe 4 are installed in the fresh air box 1, and the water supply pipe 4 is located above the corresponding wet film 3 to allow the water fed through the water supply pipe 4 to fall onto the wet film 3.

[0037] One side of the wet film 3 covers the end surface of the heat exchange core 2, so that the air flowing into or out of each air flow channel 21 of the heat exchange core 2 will pass through the wet film 3. The other side of the wet film 3 covers the fresh air inlet 11, so that the air flowing into or out of the fresh air box 1 through the fresh air inlet 11 will pass through the wet film 3.

[0038] A support frame 5 is installed between the two fresh air boxes 1. The support frame 5 is located below the heat exchange core 2. A heat exchange fan 6 is installed on the vent set in the support frame 5. The heat exchange fan 6 drives the airflow to flow upward, blows into the gaps between the air flow channels 21 of the heat exchange core 2, and flows out from the upper side of the heat exchange core 2, thereby passing through the heat exchange core 2 from bottom to top.

[0039] When in use, the fresh air outlet 11 of the first fresh air box 1 is connected to the air inlet of the fresh air fan, and the fresh air outlet 11 of the second fresh air box 1 is connected to the outdoor vent on the wall of the data center computer room. When the fresh air fan is running, the outdoor air is introduced into the adjacent second fresh air box 1 through the outdoor vent, passes through the wet film 3 of the fresh air box 1, enters each air flow channel 21 of the heat exchange core 2, and then passes through the wet film 3 at the other end to enter the first fresh air box 1, and then enters the fresh air fan through the fresh air outlet 11 of the first fresh air box 1 for filtration.

[0040] In the process of outdoor air flowing into the fresh air fan in the above manner and being blown into the computer room of the data center by the fresh air fan, since the outdoor air is drier, its humidity is lower than that of the indoor air of the computer room. The water pump sends the water in the water tank into the water supply pipe 4 through the pipeline. The water in the water supply pipe 4 further falls and enters the wet film 3. The wet film 3 is moistened, so that the outdoor air passing through is humidified, thereby reducing or even eliminating the humidity difference between the fresh air sent in by the fresh air fan and the indoor air, and keeping the indoor air humidity of the computer room constant; at the same time, since the operation of the equipment in the computer room of the data center generates a lot of heat, the indoor air The temperature is higher than that of the outdoor air. The temperature and humidity pretreatment device of the present application is located in the machine room as a whole. The heat exchange fan 6 drives the indoor air to pass through the heat exchange core 2 from bottom to top. In the process of passing through the heat exchange core 2, the indoor air exchanges heat with the outdoor air flowing through each air flow channel 21 of the heat exchange core 2, thereby increasing the temperature of the outdoor air entering the fresh air fan and being sent into the machine room by it. It not only uses the relatively low temperature outdoor air to cool and dissipate the indoor air, thereby reducing the load of the air conditioning equipment in the machine room, but also reduces the temperature difference between the fresh air and the indoor air, thereby maintaining a constant temperature and humidity working environment in the machine room. Finally, the temperature and humidity pretreatment device works in the above manner, so that the fresh air system can introduce outdoor fresh air into the machine room while maintaining a constant temperature and humidity working environment in the machine room, thereby maintaining stable operation of the equipment in the machine room.

[0041] In addition, in winter, when the outdoor temperature is cold and the air is dry, only the water supply pipe 4 in the first fresh air box 1 delivers moisture to the wet film 3 below it, so that it humidifies the outdoor air passing through. The water supply pipe 4 of the second fresh air box 1 does not input moisture, and the wet film 3 below it remains dry. Since the dry wet film 3 covers the corresponding fresh air outlet 11, and the fresh air outlet 11 is connected to the outdoor vent, the dry wet film 3 serves as a heat preservation structure to maintain the temperature of the first fresh air box 1 inside, and prevents the wet film 3 in the first fresh air box 1 from freezing due to too low a temperature, and thus prevents the outdoor air flow channel from being blocked, so as to keep the fresh air system running smoothly. Since the heat exchange fan 6 is located at the lower side, the temperature generated by its operation will also pass through the heat exchange core 2 with the indoor air, and exchange heat with the outdoor air flowing through, thereby achieving heat dissipation and cooling of the heat exchange fan 6.

[0042] In the above-mentioned schematic embodiment, the temperature and humidity pretreatment device based on the fresh air system of the data center allows the outdoor air to enter the fresh air box 1 at one end before entering the fresh air fan for filtration, and then enter the fresh air box 1 at the other end through the heat exchange core 2, and then enter the fresh air fan. The heat exchange fan 6 drives the indoor air flow from bottom to top through the heat exchange core 2, and exchanges heat with the outdoor air passing through the heat exchange core 2, which not only realizes indoor heat dissipation, but also makes the temperature of the outdoor air sent in close to the indoor air, avoiding drastic changes in temperature in the data center computer room; before the outdoor air enters the fresh air fan, it also passes through the wet film 3 wetted by water to increase its humidity, so that its humidity is basically consistent with the humidity of the indoor air, avoiding drastic changes in humidity caused by the outdoor air being sent into the data center computer room, and finally maintaining a constant temperature and humidity environment in the data center, ensuring stable operation of equipment in the data center, and solving the problem that the current data center fresh air system is prone to temperature and humidity fluctuations that cause equipment damage.

[0043] In some embodiments, a water receiving trough 12 is provided at the bottom of the fresh air box 1, and the water receiving trough 12 is located below the wet membrane 3. The water fed into the wet membrane 3 through the water supply pipe 4 will gather at the bottom of the wet membrane 3 due to its own gravity, and then seep out of the wet membrane 3. The water receiving trough 12 receives the water seeping out of the wet membrane 3, so as to prevent the seeped water from flowing freely in the fresh air box 1, and then being exposed and spilled into the machine room, thereby preventing water leakage, and ensuring a clean environment in the machine room.

[0044] In some embodiments, the fresh air box 1 is connected to a drain pipe 13 connected to the water receiving tank 12. The seepage water collected by the water receiving tank 12 is sent out through the drain pipe 13 to prevent the water receiving tank 12 from spilling due to fullness, thereby preventing water leakage in the fresh air box 1. In addition, the water discharged through the drain pipe 13 can be sent back to the water tank, so that it can be transported to the wet membrane 3 again through the water pump and the water supply pipe 4, so as to realize the recycling of water and avoid the waste of water resources.

[0045] In some embodiments, a horizontally arranged orifice plate 14 is installed at the top of the water receiving trough 12, and the wet film 3 falls on the orifice plate 14. The water-permeable holes on the orifice plate 14 ensure that the water seeping from the wet film 3 can pass through the orifice plate 14 and fall into the water receiving trough 12. At the same time, the orifice plate 14 supports the wet film 3 to prevent the wet film 3 from falling into the water receiving trough 12 and soaking in the accumulated water, thereby preventing the wet film 3 from softening and collapsing due to long-term soaking, maintaining the shape of the wet film 3 stable, maintaining the wet film 3 covering the end surface of the heat exchange core 2 and the fresh air outlet 11, ensuring that all the outdoor air flowing through fully passes through the wet film 3, thereby maintaining the humidification effect of the wet film 3 on the outdoor air.

[0046] In some embodiments, the water supply pipe 4 is arranged horizontally, extending from one side into the fresh air box 1, and extending to the other side inside the fresh air box 1, and a plurality of water outlets are arranged along the axial direction of the water supply pipe 4. The water supply pipe 4 delivers water to each position of the wet film 3 through the plurality of water outlets, ensuring that each position of the wet film 3 can be completely wetted, thereby ensuring the humidification effect of the wet film 3 on the outdoor air.

[0047] In some embodiments, a spray head 41 is installed on the water outlet, and the spray head 41 is arranged downward. The water mist sprayed by the spray head 41 can be dispersed to a larger range, so as to wet each position of the wet film 3 more quickly and fully, thereby improving the effect and efficiency of comprehensive wetting of the wet film 3.

[0048] In some embodiments, the fresh air box 1 has a fresh air duct 15 on one side away from the heat exchange core 2, the fresh air port 11 is a port at one end of the fresh air duct 15 away from the heat exchange core 2, and the wet film 3 covers the port at the other end of the fresh air duct 15. A tubular structure is provided on the fresh air box 1 to keep the fresh air port 11 away from the wet film 3, further reducing the risk of water seeping from the wet film 3 spilling out through the fresh air port 11.

[0049] In some embodiments, a temperature and humidity sensor 7 is installed in each of the fresh air ducts 15. The fresh air duct 15 provides an installation space for the temperature and humidity sensor 7. The temperature and humidity sensors 7 of the two fresh air boxes 1 can respectively measure the temperature and humidity of the outdoor air, as well as the temperature and humidity of the fresh air after passing through the two wet films 3 and the heat exchange core 2, so that the control device can control the operating speed of the heat exchange fan 6 and the water supply speed of the water supply pipe 4 according to the difference in temperature and humidity on both sides, and adjust the temperature and humidity of the fresh air to make it as close to or even the same as the temperature and humidity of the indoor air as possible, so as to ensure a constant temperature and humidity environment in the machine room.

[0050] In some embodiments, a temperature and humidity sensor 7 extending between the heat exchange fan 6 and the heat exchange core 2 is installed at the bottom of the fresh air box 1 to measure the temperature and humidity of the indoor air before passing through the heat exchange core 2.

[0051] In some embodiments, an air valve 8 is installed between the two fresh air boxes 1, the air valve 8 is connected to the top of the heat exchange core 2, and a temperature sensor is installed in the air valve 8. The temperature and humidity of the indoor air before and after passing through the heat exchange core 2 are measured by two temperature and humidity sensors 7 distributed above and below the heat exchange core 2, respectively, so that the control device can control the operating speed of the heat exchange fan 6 and the opening of the air valve 8 according to the difference in temperature and humidity between the upper and lower sides, and adjust the temperature and humidity of the fresh air while ensuring the temperature drop of the indoor air, so that it is as close to or even the same as the temperature and humidity of the indoor air as possible, so as to ensure a constant temperature and humidity environment in the machine room.

[0052] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0053] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
