Description

Technology Field

[0001] The present invention relates to a device capable of heat exchange and ventilation of internal and external air in a data center, and more specifically, to a data center heat exchange ventilation device configured such that, during the process of discharging high-temperature hot air generated from servers to the outside at the discharge section and supplying cold air to a low-temperature room after cooling by drawing in outside air at the intake section, a heat exchange section is provided between the discharge section and the intake section to provide heat to the outside air drawn in along the path. Background Technology

[0002] With the recent advancement of artificial intelligence (AI) computing technology, high-performance GPUs and AI servers are being introduced into data centers on a large scale. Because these AI servers perform highly parallel computations, they generate significantly more heat than conventional servers, leading to a problem of rapidly increasing cooling and air conditioning loads in data centers.

[0003] Conventional data centers maintain constant temperature and humidity in server rooms using Air Handling Units (AHUs). These units are designed to supply cooling air at 12–18°C to remove heat generated by server racks, while maintaining clean zones at 20–24°C and humidity levels of 40–60%. However, when equipment that continuously emits high heat, such as AI servers, is densely installed, the capacity of the AHUs becomes excessively large, leading to a problem where energy consumption for cooling units and humidity control devices skyrockets.

[0004] In particular, the high-temperature zones of AI servers continuously emit heat of approximately 40–60°C; therefore, if this heat flows into the data center, the cooling load increases and energy efficiency decreases. Existing technologies primarily used a method of simply venting this high-temperature air to the outside, but this resulted in wasting waste heat and causing significant energy waste.

[0005] To address this, technologies have recently been proposed that recover energy or improve outdoor air cooling efficiency by performing heat exchange with the outside air using a heat exchanger during the process of discharging high-temperature air to the outside. However, conventional heat exchange methods have drawbacks, such as the potential for contaminant ingress due to direct contact between the high-temperature air and the outside air, and difficulties in efficient temperature control.

[0006] Therefore, there is a need for a new air conditioning system for data centers that can efficiently manage the high-temperature exhaust air from AI servers to reduce the cooling load of the constant temperature and humidity control unit, while simultaneously saving energy through heat exchange with the outside air. Prior art literature

[0007] Korean Intellectual Property Office Application No. 10-2015-0002066 (2015-01-07) The problem to be solved

[0008] The present invention has been devised to solve the aforementioned conventional problems, and the objective of the present invention is to efficiently manage the large amount of waste heat generated in AI high-temperature servers, thereby reducing the capacity and cooling load of the data center's constant temperature and humidity control unit and improving the energy efficiency of the entire system.

[0009] In addition, the purpose is to reduce the operating load of the cooler and achieve a reduction in data center operating costs by recovering energy through a heat exchanger or utilizing it for cooling the outside air, instead of directly releasing high-temperature air to the outside. means of solving the problem

[0010] The AI ​​data center heat exchange ventilation device according to the present invention comprises a constant temperature and humidity unit and a server, a high-temperature room to which hot air generated from the server is moved, and a low-temperature room to which filtered low-temperature cold air is received, and is a ventilation device for a data center that provides cold air from the low-temperature room to the server. It may include an exhaust unit that sucks in hot air inside the high-temperature room and discharges the hot air to the outside, an intake unit provided adjacent to the exhaust unit and connected to the exhaust unit, which sucks in outside air from the outside and guides it to the low-temperature room, and a heat exchange unit provided between the exhaust unit and the intake unit to heat exchange the hot air and the cold air.

[0011] In addition, the discharge section and the suction section may be arranged vertically in a stacked form, and the heat exchange section may be formed vertically in an elongated manner.

[0012] In addition, the above suction part may have an outside air inlet formed on one side for drawing in outside air, and a low-temperature air inlet on the other side that communicates with the low-temperature room.

[0013] In addition, the heat exchanger can exchange heat with the hot air of the discharge section to cool the outside air sucked into the suction section.

[0014] And the above intake portion may further include a cooling member provided between the heat exchange portion and the low-temperature air inlet to cool the heat-exchanged outside air.

[0015] In addition, the suction part is formed to be expandable, so that a portion disposed in the discharge part can be extended toward the suction part.

[0016] And the above intake part may further include a UV lamp member that irradiates UV light in the low-temperature air inlet or inside the intake part adjacent to the low-temperature air inlet, and a filter is provided inside to purify the air moving to the low-temperature room. Effects of the invention

[0017] The present invention utilizes high-temperature air for heat exchange rather than simply discharging it, thereby reducing the cooling load of a constant temperature and humidity unit by about 30 to 70%, and has the effect of lowering the operating load of an outdoor air cooler and reducing the total power consumption through waste heat recovery.

[0018] In addition, it is possible to minimize temperature variations inside the server room and stably maintain a clean zone within the range of 20 to 24°C.

[0019] In addition, by installing a filter for removing harmful gases (ozone, benzene, formaldehyde, etc.) inside the heat exchanger, indoor air quality can be improved and corrosion and contamination of computer equipment can be prevented. Brief explanation of the drawing

Specific details for implementing the invention

[0021] A preferred embodiment according to the present invention will be described in detail below with reference to the attached drawings.

[0022] The advantages and features of the present invention and the method for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.

[0023] However, the present invention is not limited by the embodiments disclosed below but may be implemented in various different forms, and these embodiments are provided merely to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0024] In addition, in describing the present invention, if it is determined that related known technologies, etc., may obscure the essence of the present invention, a detailed explanation thereof will be omitted.

[0025] The present invention relates to a heat exchange ventilation device for a data center (1), and includes a constant temperature and humidity unit (5) and a server (3) inside the data center (1), and has the purpose of maintaining the data center (1) at 12 to 15 degrees by heat exchange with heat generated from the server (3).

[0026] Specifically, the ventilation device of the present invention for a data center (1) includes a constant temperature and humidity unit (5) and a server (3), a high-temperature room (7) to which hot air generated from the server (3) is moved, and a low-temperature room (9) to which filtered low-temperature cold air is received, and the configuration of the present invention for providing cold air from the low-temperature room (9) to the server (3) may include an exhaust unit (100), an intake unit (300), and a heat exchange unit (500).

[0027] First, the exhaust unit (100) can suck in hot air inside the high-temperature room (7) and discharge the hot air to the outside.

[0028] And the suction part (300) is provided adjacent to the discharge part (100) and connected to the discharge part (100), and can suck in outside air from the outside and guide it to the low-temperature room (9).

[0029] In addition, the heat exchanger (500) is provided between the discharge section (100) and the suction section (300) to exchange heat between hot air and cold air.

[0030] The present invention may be provided in the form of a module that can be installed in an existing data center (1), and may have the purpose of reducing energy consumption and stably maintaining the internal temperature of the data center (1) while the temperature and humidity control unit (5) continuously controls the temperature and humidity against the high temperature heat generated from the server (3).

[0031] The present invention will be described in detail with reference to the drawings.

[0032] FIG. 1 is a schematic diagram for explaining the overall contents of a heat exchange ventilation device of a data center (1) according to one embodiment of the present invention.

[0033] As described above, a server (3) and a temperature and humidity control unit (5) are provided inside the data center (1), and high heat is generated in the server (3), and the temperature and humidity control unit (5) can be operated to maintain the indoor temperature and humidity at a constant level.

[0034] In addition, a low-temperature room is formed on one side and a high-temperature room is formed on the other side, centered on the indoor space where the server (3) and the temperature and humidity control unit (5) are arranged. The high-temperature room may include an intake duct (122) that is connected to the exhaust unit and sucks in air inside the high-temperature room, and a high-temperature air intake port (120) that connects the intake duct (122) to the exhaust unit (100) and serves as a passage for air to move.

[0035] And a high-temperature air intake port (120) may be formed on one side of the discharge section (100), and a high-temperature air exhaust port (140) through which high-temperature hot air is discharged to the outside may be formed on the other side of the discharge section (100).

[0036] Additionally, the intake section (300) provided at the top of the exhaust section (100) may have an external air intake port (340) formed on one side for external air intake, and on the other side of the intake section (300), a low-temperature air inlet (320) may be formed to communicate with the low-temperature room (9) and serve as a passage for air to cool or heat the external air and move to the low-temperature room.

[0037] And the low-temperature air inlet (320) is connected to the low-temperature room (9), and an injection duct (322) is formed at the end so that air from the suction part (300) can be supplied to the low-temperature room through the injection duct (322).

[0038] And due to the high heat generated in the server (3), the surrounding hot air can be moved to a high-temperature room (7) separated from the server (3) and then discharged to the outside through the discharge section (100).

[0039] Since the outside air is between -10°C and 32°C, the high-temperature hot air discharged from the discharge unit (100) is between 40°C and 60°C, so it may be advantageous for energy saving to discharge the high temperature of the server (3) and use the outside air.

[0040] The outside air varies depending on the winter and summer seasons, but since the outside air is at a lower temperature than the temperature emitted from the server (3) even in the summer season, it is preferable to use the outside air.

[0041] Therefore, the hot air from the discharge section (100) is discharged, and during the summer, the intake section (300) can filter and cool the outside air and inject it into the low-temperature room (9).

[0042] If sub-zero outside air enters the intake section (300) during the winter season, the sub-zero outside air can raise its temperature through the heat exchange section (500).

[0043] In this way, ventilation between the data center (1) and the outside is performed through the heat exchanger (500), so that the space containing the server (3) can be maintained at 20°C to 24°C.

[0044] Next, the discharge section (100) and the suction section (300) will be described in detail.

[0045] FIGS. 2 and FIGS. 3 are drawings showing an exhaust section (100), an intake section (300), and a heat exchange section (500) of a heat exchange ventilation device of a data center (1) according to an embodiment of the present invention.

[0046] As described, it has a stacked form in which a discharge section (100) is positioned at the bottom and a suction section (300) is positioned at the top, and it can be seen that the discharge section (100) and the suction section (300) are formed in the form of a casing.

[0047] First, the exhaust section (100) has a high-temperature air intake port (120) formed on one side that serves as a passage connecting to the high-temperature room (7), and an exhaust section filter member (160) may be formed inside the exhaust section (100) adjacent to the high-temperature air intake port (120).

[0048] And on the other side of the discharge section (100), a high-temperature air exhaust port is formed that communicates with the outside, and an exhaust pump (124) is connected inside the discharge section (100) adjacent to the high-temperature air exhaust port to provide the speed of exhaust.

[0049] A passage is formed at the center of the discharge section (100) that is open to the top and communicates with the suction section (300), and the suction section (300) can be formed at the top of the passage, having the shape of a casing of the same size as the discharge section (100).

[0050] The intake section (300) has an external air intake port (340) formed on one side that protrudes in the same direction as the high-temperature air placement port, and an intake section filter member (360) may be formed inside the intake section (300) adjacent to the external air intake port (340).

[0051] And on the other side of the suction part (300), a low-temperature air inlet (320) is formed to serve as a passage for air to move to the low-temperature room (9), and an intake pump (324) may be formed inside the suction part (300) adjacent to the low-temperature air inlet (320).

[0052] Additionally, a cooling member (330) may be further formed inside the intake section (300). The cooling member (330) is formed along the path through which outside air moves to the low-temperature room (9), and may take the form of a cooler or air conditioner that cools the outside air.

[0053] And a heat exchanger (500) is formed between the outside air intake port (340) and the cooling member (330), and at this location, the lower part of the intake part (300) may be open to communicate with the discharge part (100).

[0054] The heat exchanger (500) according to the present invention may be provided in a form that moves between the suction part (300) and the discharge part (100) or extends in length.

[0055] The heat exchanger (500) transfers heat from the discharge section (100) to the air in the intake section (300), and in one embodiment of the present invention for this purpose, the heat exchanger (500) may have a structure that is raised and lowered.

[0056] In the present invention, the heat exchanger (500) may include a heat conduction member (520), a traction member (540), a rib bar member (560), and a motor member (580).

[0057] First, the heat conduction member (520) can be formed from a material of a conductor through which heat from the high-temperature room is transferred in the discharge section (100).

[0058] And a motor member (580) is provided on the upper part of the suction part (300), and the motor member (580) is connected to a heat conduction member (520) so as to raise and lower the heat conduction member (520).

[0059] The motor member (580) is coupled to the heat conduction member (520) by a long traction member (540), and the traction member (540) is configured to be adjustable in length in the connection passage between the suction part (300) and the discharge part (100) at the upper part of the suction part (300), and one end may be coupled in a form that is wound onto the motor member (580), and the other end may be coupled to the upper part of the heat conduction member (520).

[0060] To this end, the other end of the traction member (540) may be formed horizontally along the side width direction of the heat conduction member (520), and a rib bar member (560) may protrude downward from a portion and be combined with the heat conduction member (520).

[0061] Here, the width direction of the heat conduction member (520) can be the direction from the high-temperature air intake (120) toward the high-temperature air exhaust.

[0062] Alternatively, the traction member (540) is formed radially laterally at an orthogonal end of the heat conduction member (520), and the rib bar member (560) protrudes downward toward the lower end and can be coupled to the heat conduction member (520).

[0063] The rib bar member (560) may be a material having long rigidity, and the rib bar member (560) may be connected to the inner lower surface of the discharge portion (100) by penetrating the heat conduction member (520).

[0064] This feature may guide the heat conduction member (520) to move up and down without shaking through the rib bar member (560).

[0065] Through the shape of the aforementioned traction member (540) and rib bar member (560), the heat exchanger (500) of the heat exchange ventilation device of the data center (1) of the present invention can receive heat from the hot air moving from the exhaust part (100) to the high-temperature room (7) during the winter season, and transfer heat to the outside air moving upward to the low-temperature room (9).

[0066] In winter, the outside air may be below freezing, and when heat is transferred to the outside air to maintain the area around the server (3) at 18°C ​​to 22°C, the heat from the hot air of the exhaust part (100) can be taken and transferred to the outside air that has entered the intake part (300).

[0067] This allows heat to be transferred to the outside air using the winter heat, making it possible to raise the temperature without using energy to heat the outside air.

[0068] In another embodiment of the present invention, the heat exchanger (500) may be formed extending from the discharge section (100) to the suction section (300).

[0069] FIG. 4 is a drawing showing the length of the heat exchanger (500) being extended in a heat exchange ventilation device of a data center (1) according to a modified embodiment of the present invention.

[0070] As described, the rib bar member (560) is formed long and penetrates the heat conduction member (520) and is coupled to the inner lower surface of the discharge portion (100).

[0071] And the traction member (540) is combined with the upper end of the rib bar member (560) that penetrates the heat conduction member (520) and is located on the upper inner side of the suction part (300).

[0072] And in this embodiment as well, the heat-conducting member (520) can be formed as a conductor.

[0073] Through this, the high temperature of the discharge section (100) heats the lower part of the heat conduction member (520), and as the heat moves upward, heat can be transferred to the upper part of the heat conduction member (520).

[0074] And the outside air sucked into the suction part (300) passes through the heat conduction member (520) and its temperature rises, and as the outside air with the raised temperature moves to the server (3), energy for the constant temperature and humidity device (5) to heat the server (3) to a temperature maintained by the server (3) can be saved.

[0075] According to another embodiment of the present invention, the heat-conducting member (520) is composed of a liquid refrigerant and can perform heat exchange.

[0076] In this embodiment, the heat conducting member (520) is arranged in a manner such that a plurality of liquid refrigerants are arranged along the direction in which outside air moves from the intake section (300), and the heat conducting member (520) may be formed in a long shape extending from the discharge section (100) toward the intake section (300).

[0077] In this way, the heat conducting member (520) is formed extending from the inner bottom of the discharge section (100) to the inner upper part of the suction section (300), so that heat from the hot air exhausted from the discharge section (100) is transferred to the liquid refrigerant, and as the heat from the lower part of the liquid refrigerant is transferred to the upper part, heat can be provided to the outside air passing through the suction section (300).

[0078] Specifically, in this embodiment, the heat-conducting member (520) has a tube (not shown) through which air moves formed inside the discharge section (100) and the suction section (300) which are arranged vertically, and the tube may have a zigzag shape formed so that it is formed horizontally and the end is bent to form a parallel vertically.

[0079] And the surface of the above tube is wrapped with a liquid refrigerant, and this refrigerant can transfer temperature to the tube.

[0080] In addition, the pipe of the discharge section (100) and the pipe of the suction section (300) are connected by a pump, which may be for moving air inside the pipe from the discharge section (100) to the suction section (300).

[0081] Accordingly, in the discharge section (100), the liquid refrigerant transfers high-temperature heat to the pipe placed in the discharge section (100), and transfers high-temperature heat inside the discharge section (100) to the pipe of the suction section (300).

[0082] And the cold air at low temperature sucked into the intake section (300) during winter can undergo heat exchange inside the intake section (300) through the pipe.

[0083] Next, we will examine a modified embodiment of the present invention.

[0084] According to a modified embodiment of the present invention, the shape of the intake part (300) and the exhaust part (100) can be modified to facilitate the entry and exit of air.

[0085] FIG. 5 is a drawing showing that the shape of the exhaust part (100) of the heat exchange ventilation device of a data center (1) according to a modified embodiment of the present invention has been modified.

[0086] As described, both sides of the discharge section (100) and the suction section (300) may have a shape that becomes smaller in size towards the ends.

[0087] To explain the intake port as an example, the intake section (300) has a heat exchange section (500) formed in the center of the body, an outside air intake port (340) formed on one side, and a low-temperature air inlet (320) formed on the other side.

[0088] And the upper and lower surfaces can be formed at an angle along one side from the center of the body of the suction part (300) so as to be closer to each other toward the outside air intake port (340).

[0089] The other side of the suction part (300) has the same shape as this, and the discharge part (100) may have a shape in which the opening of both sides becomes narrower towards the end, just like the suction part (300).

[0090] This shape may be intended to narrow the entrances and exits of the intake section (300) and the exhaust section (100) and to increase their size as air moves toward the center, thereby allowing the time for heat exchange to be relatively longer at the center equipped with the heat exchange section (500), and also to accelerate the movement of air from the intake section (300) to the low-temperature air inlet (320).

[0091] This allows the density of the air to increase while there is airflow through the low-temperature air inlet (320), and at this time, the air can be moved quickly by forcibly exhausting it with the intake pump (324).

[0092] Meanwhile, in the heat exchange section (500), the heat conduction member (520) has a structure that moves up and down, and it was shown that two are formed.

[0093] And the heat conduction member (520) may be connected to the motor member (580) so that it can be individually raised and lowered.

[0094] In this configuration, when hot air from the high-temperature room (7) is discharged to the outside during the winter season, high-temperature heat is transferred to two heat-conducting members (520), and when both heat-conducting members (520) are moved to the intake section (300), the outside air below freezing during the winter season comes into contact with the heat-conducting members (520) for a relatively longer time than when there is only one heat exchanger (500), thereby allowing the temperature of the outside air to be raised significantly compared to when it comes into contact with only one heat-conducting member (520).

[0095] Therefore, depending on the external temperature, the heat conduction member (520) of the heat exchanger (500) may be moved upward by selecting one or two options.

[0096] Meanwhile, in another modified embodiment of the present invention, the heat exchanger (500) may have a structure that is raised or lowered when combined or separated.

[0097] I will explain by referring to the drawings.

[0098] FIG. 6 is a diagram showing a structure in which a heat exchanger (500) is raised and lowered in a heat exchange ventilation device of a data center (1) according to a modified embodiment of the present invention, and FIG. 7 is a diagram showing a structure in which heat can be transferred by a thermoelectric element in a heat exchange ventilation device of a data center (1) according to a modified embodiment of the present invention.

[0099] As described above, in this embodiment, the heat-conducting member (520) may further include a lower body (522), a rail (524), and a movable body (526).

[0100] First, the lower body (522) may be formed of a conductor made of a material capable of heat conduction, and a movable body (526) may be accommodated in the lower body (522) and then rise to the top, and the movable body (526) and the lower body (522) may be connected by a rail (524).

[0101] In addition, a motor member (580), a traction member (540), and a rib bar member (560) are combined on the upper part of the movable body (526) to provide power to raise and lower the movable body (526).

[0102] Here, the movable body (526) and the lower body (522) can be formed in a shape where straight lines intersect each other along the lateral or vertical direction.

[0103] For example, as shown in FIG. 7, the lower body (522) is formed long along the direction of the outside air intake from the low-temperature air inlet (320) with respect to the intake part (300), and can be formed in a plurality of bar shapes inside.

[0104] And the above bars are formed to be spaced apart from adjacent bars at a predetermined distance, and can be arranged in such a way that the bars of the movable body (526) are inserted into the spaced gap.

[0105] At this time, the bar of the lower body (522) and the bar of the moving body (526) are not in contact with each other and a predetermined gap is formed, so that heat exchange can be achieved when air moves through the gap.

[0106] Alternatively, the movable body (526) and the lower body (522) may be formed to overlap each other in a grid shape, or may have a shape in which protrusions and grooves are repeated in a zigzag shape, and in this case, the grooves of the movable body (526) are inserted into the protrusions of the lower body (522), and the protrusions of the movable body (526) are inserted into the grooves of the lower body (522), so that they may overlap.

[0107] Meanwhile, the present invention has the purpose of reducing the energy consumption of the constant temperature and humidity unit (5) through the heat exchange unit (500).

[0108] Therefore, a control unit (700) capable of controlling the constant temperature and humidity unit (5) in response to the outside temperature may be further included.

[0109] Figure 8 describes a method of automatically controlling the temperature using the control unit (700).

[0110] FIG. 8 is a diagram showing that a control unit (700) controls an intake unit (300) and a constant temperature and humidity unit (5) in a heat exchange ventilation device of a data center (1) according to a modified embodiment of the present invention.

[0111] The control unit (700) according to the present invention is connected to the constant temperature and humidity unit (5), the exhaust unit (100), the suction unit (300), and the heat exchange unit (500), and may include a temperature sensor to receive external temperature information, and may include communication equipment to receive weather information through a meteorological agency or media.

[0112] Through this configuration, the control unit (700) receives current weather and future weather information through weather forecasts and controls the heat exchange unit (500) according to the temperature of the outside air, that is, it can control the heat conduction member (520) to move to or extend the suction unit (300), and can also control the operation of the cooling member (330).

[0113] Accordingly, when outside air is sucked into the intake section (300), it is determined whether to operate the cooling member (330) or the heat conducting member (520) according to the temperature of the outside air. If it is determined that the temperature of the outside air is higher than the temperature of the low-temperature room (9), the cooling member (330) is operated without raising the heat conducting member (520), and if it is determined that the temperature of the outside air is lower than the temperature of the low-temperature room (9), the operation of the cooling member (330) is stopped and the heat conducting member (520) can be raised into the discharge section (100).

[0114] Although specific embodiments regarding the heat exchange ventilation device of the data center (1) according to the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0115] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
