Description

Technical Field

[0001] The present invention relates to the technical field of electronic facilities, and in particular to a cabinet system. Background Art

[0002] With the rapid development of computer technology and the Internet, the number of services provided by the Internet is increasing day by day. In particular, emerging technologies such as cloud computing are inseparable from people's lives. Therefore, the demand for data centers is also increasing day by day.

[0003] The computer room of the data center is equipped with a cabinet system, which includes multiple cabinets and a cooling system for dissipating heat from the cabinets. The cabinet includes a cabinet body and electronic equipment such as computers, servers, storage devices, network communication devices, etc. arranged in the cabinet body. Among them, the electronic equipment itself has a fan, which can guide the airflow from the windward side of the electronic equipment to the wind outlet side, so that the electronic equipment can exchange heat with the airflow and cool down.

[0004] The heat exchange coil of the cooling system is arranged on the side wall of the cabinet corresponding to the air outlet surface of the electronic equipment. In this way, the high-temperature gas after heat exchange with the electronic equipment is cooled by the heat exchange coil during the process of being discharged from the cabinet, and the cooled low-temperature gas flows around the cabinet in the machine room until it flows to the position of the cabinet corresponding to the windward surface of the electronic equipment. After entering the cabinet, the low-temperature gas exchanges heat with the electronic equipment, and the electronic equipment is cooled to achieve heat dissipation.

[0005] However, low-temperature gas easily causes cold loss when flowing in the room, resulting in poor heat dissipation of electronic equipment. At the same time, the cooling system dissipates heat for multiple cabinets separately. When the heat exchange component of one cabinet fails, the cooling system cannot dissipate heat for the cabinet in time, causing the cabinet temperature to be too high. Summary of the invention

[0006] In view of the above problems, an embodiment of the present invention provides a cabinet system, which has a high heat dissipation effect and can avoid the problem of excessively high local temperature of the cabinet body causing electronic equipment failure.

[0007] In order to achieve the above purpose, the embodiment of the present invention provides the following technical solutions:

[0008] An embodiment of the present invention provides a cabinet system, which is arranged in a computer room. The cabinet system includes a plurality of cabinets, each cabinet includes a cabinet body and electronic equipment accommodated in the cabinet body, the electronic equipment having a windward surface and an air outlet surface arranged relatively to each other; the inner cavity of the cabinet body has a cold air zone and a hot air zone, the electronic equipment is arranged between the cold air zone and the hot air zone, the cold air zone corresponds to the windward surface of the electronic equipment, and the hot air zone corresponds to the air outlet surface of the electronic equipment; and a heat exchange component is provided on the side wall of the cabinet body corresponding to the cold air zone, which is used to cool the gas in the computer room and then introduce it into the cold air zone; the electronic equipment can guide the cooled gas from the windward surface to the air outlet surface; the side wall of the cabinet body corresponding to the hot air zone is provided with an exhaust hole, which is used to guide the gas after heat exchange with the electronic equipment into the computer room; wherein the cold air zones of two adjacent cabinets can be interconnected.

[0009] In some optional embodiments, the cabinet system is further provided with a baffle and a baffle driver, the baffle is connected to the baffle driver, the baffle is arranged at the connecting position between two adjacent cabinets, and the baffle driver can drive the baffle to move to connect or disconnect two adjacent cabinets.

[0010] In some optional embodiments, the electronic device is provided with a temperature measuring component for detecting the temperature of the electronic device when it is working; the baffle is used to connect or disconnect two adjacent cabinets according to the temperature measured by the temperature measuring component.

[0011] In some optional embodiments, the cabinet system is also provided with a first duct fan, which is arranged at the connecting position between two adjacent cabinets. The first duct fan can rotate forward or reverse according to the temperature measured by the temperature measuring component so that the cooled gas can circulate between the two adjacent cabinets.

[0012] In some optional embodiments, the cabinet system further includes an air duct, both ends of which are detachably connected to two adjacent cabinets, and the cabinets are provided with air outlets connected to the air duct; and the baffle is arranged in the air duct.

[0013] In some optional embodiments, the cabinet further includes a filter element, which is disposed at the air outlet to filter the air flow introduced into the cabinet.

[0014] In some optional embodiments, the air guide tube is made of a flexible material.

[0015] In some optional embodiments, there are multiple electronic devices, and the multiple electronic devices are arranged at intervals in the cabinet; the heat exchange component includes a heat exchange coil with a cooling medium flowing therethrough, the heat exchange coil includes a plurality of heat exchange units arranged in parallel, and a first switch valve is provided at the inlet end of each heat exchange unit; each electronic device is correspondingly provided with at least one heat exchange unit.

[0016] In some optional embodiments, there are multiple heat exchange coils, which are arranged in parallel along the flow direction of the gas, and a second switch valve is provided at one end of each heat exchange coil.

[0017] In some optional embodiments, a second fan is provided at the exhaust hole to guide the gas in the hot air zone of the cabinet into the machine room.

[0018] Compared with the prior art, the cabinet system provided by the embodiment of the present invention has the following advantages: by arranging a heat exchange component on the windward side of the electronic equipment, the cooled low-temperature gas can be introduced into the cold air zone of the cabinet, so that the low-temperature gas can exchange heat with the electronic equipment, and the high-temperature gas after the heat exchange is discharged to the outside of the cabinet, that is, the high-temperature gas is discharged into the machine room. That is to say, the air inlet side of the cabinet in this embodiment corresponds to the cold air zone, and the air outlet side corresponds to the hot air zone.

[0032] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0033] In the prior art, low-temperature gas will circulate in the machine room. During the circulation of low-temperature gas, it is easy to exchange heat with the cabinet, the side wall of the machine room, etc., causing the temperature of the low-temperature gas to rise. In this way, the low-temperature gas with the increased temperature enters the cabinet again to exchange heat with the electronic equipment, resulting in poor heat dissipation effect. At the same time, the cooling system dissipates heat for multiple cabinets at the same time. When a heat dissipation failure occurs in one of the cabinets, the cooling system cannot dissipate heat for the faulty cabinet in time, causing the temperature of the electronic equipment in the cabinet to be too high.

[0034] In view of this, the embodiment of the present application arranges the heat exchange component on the side wall of the cabinet corresponding to the windward side of the electronic equipment, so that the low-temperature gas after cooling directly enters the cabinet and exchanges heat with the electronic equipment, and the flow path of the low-temperature gas becomes smaller, thereby optimizing the heat dissipation effect. At the same time, the cold air areas of the two adjacent cabinets are connected, so that the low-temperature gas in the two adjacent cabinets can circulate with each other. When a heat dissipation failure occurs in one of the cabinets, it can obtain low-temperature gas from the adjacent cabinet for heat dissipation, thereby preventing the temperature of the electronic equipment in the faulty cabinet from being too high.

[0035] Figure 1 A schematic diagram of the structure of a cabinet system provided in an embodiment of the present invention. Figure 2 for Figure 1 Schematic diagram of the structure of the middle cabinet. Figure 3 for Figure 1 Schematic diagram of the cross-sectional view of the cabinet.

[0036] See also Figures 1 to 3 The embodiment of the present invention provides a cabinet system, which is arranged in a machine room (not shown). The cabinet system includes a plurality of cabinets 10. Each cabinet 10 includes a cabinet body 11 and an electronic device 12 accommodated in the cabinet body 11. The electronic device 12 has a windward surface and a wind outlet surface that are arranged oppositely. The inner cavity of the cabinet body 11 has a cold air zone 111 and a hot air zone 112. The electronic device 12 is arranged between the cold air zone 111 and the hot air zone 112. The cold air zone 111 corresponds to the windward surface of the electronic device 12. The wind zone 112 corresponds to the air outlet surface of the electronic device 12; and a heat exchange component is provided on the side wall of the cabinet 11 corresponding to the cold air zone 111, which is used to cool the gas in the computer room and introduce it into the cold air zone 111; the electronic device 12 can guide the cooled gas from the windward surface to the air outlet surface; the side wall of the cabinet 11 corresponding to the hot air zone 112 is provided with an exhaust hole, which is used to guide the gas after heat exchange with the electronic device 12 into the computer room; wherein, the cold air zones 111 of two adjacent cabinets 11 can be interconnected.

[0037] Specifically, the computer room can be understood as a house, a container, etc. in the art. A plurality of cabinets 10 are arranged in the computer room. The cabinets 10 include a cabinet body 11 and electronic equipment 12. The cabinets 10 may be sheet metal structures. The electronic equipment 12 may include any one or more of computers, servers, storage devices, network communication devices, etc.

[0038] The space in the cabinet 11 can be divided into multiple independent accommodating cavities by partitions, and each accommodating cavity space can be used to place an electronic device 12. That is, the number of electronic devices 12 in each cabinet 11 is multiple, and multiple electronic devices 12 are arranged in the cabinet 11 at intervals.

[0039] It is understandable that the electronic device 12 itself has a cooling fan to drive airflow and dissipate heat. Then, the electronic device 12 itself forms a windward surface and a windward surface, which are arranged on opposite sides of the electronic device 12.

[0040] Correspondingly, the cabinet 11 is provided with an air inlet side and an air outlet side. The air inlet side of the cabinet 11 corresponds to the windward side of the electronic device 12 , and the air outlet side of the cabinet 11 corresponds to the air outlet side of the electronic device 12 .

[0041] Among them, after the electronic device 12 is set in the cabinet 11, the space in the cabinet 11 can be divided into three parts accordingly, namely, the part for accommodating the electronic device 12, the part of the electronic device 12 close to the air inlet side, and the part of the electronic device 12 close to the air outlet side. The three parts can be respectively called the working area 113, the cold air area 111 and the hot air area 112.

[0042] In order to dissipate heat from the cabinet 10, a cooling system is further provided in the computer room, for example, an air conditioning refrigeration system well known to those skilled in the art. The heat exchange components such as the evaporator of the air conditioning refrigeration system are used to perform heat exchange with the high-temperature gas, so that the high-temperature gas is cooled to low-temperature gas, so as to cool the electronic equipment 12 in the cabinet 10. This embodiment does not limit the type and structure of the cooling system.

[0043] Optionally, the heat exchange component in this embodiment includes a heat exchange coil 20 with a cooling medium flowing therethrough, the heat exchange coil 20 includes a plurality of heat exchange units 21 arranged in parallel, and a first switch valve 22 is provided at the inlet end of each heat exchange unit 21; each electronic device is correspondingly provided with at least one heat exchange unit 21.

[0044] The cooling medium can be low-temperature water or refrigerant, such as R410. The heat exchange coil 20 is arranged on the side wall of the air inlet side of the cabinet 11 in a serpentine reciprocating bend. When the high-temperature gas flows through the gap of the heat exchange coil 20, it exchanges heat with the cooling medium in the heat exchange coil 20. The high-temperature gas in the machine room is cooled and converted into low-temperature gas. After the cooling medium is heated, it is cooled by the cooling system to cool the gas in the machine room for the next cycle.

[0045] It can be understood that the cabinet 11 is provided with a cabinet door so that the electronic equipment 12 in the cabinet 11 is exposed by opening the cabinet door. The cabinet door can be arranged on the air inlet side of the cabinet 11, and the corresponding heat exchange coil 20 is arranged on the cabinet door and opposite to the cold air area 111. At this time, the heat exchange coil 20 can be connected to other components of the cooling system through a flexible pipeline to avoid pipeline breakage during the cabinet door opening and closing process.

[0046] A seal is provided between the cabinet door and the cabinet body 11 so that when the cabinet door is closed, the gap between the cabinet door and the cabinet body 11 is sealed to prevent low-temperature gas from leaking from the gap between the cabinet door and the cabinet body 11 and reducing the heat dissipation effect.

[0047] Considering that the electronic equipment 12 in each accommodating cavity in the machine room may not work at the same time, in this embodiment, the heat exchange coil 20 includes a plurality of heat exchange units 21 arranged in parallel, and a first switch valve 22 is provided at the inlet end of each heat exchange unit 21. In this way, the first switch valve 22 can be opened or closed according to whether the electronic equipment 12 corresponding to the heat exchange unit 21 is working, thereby reducing the power of the cooling system.

[0048] Then, different electronic devices 12 that need to work for a long time can be concentrated in a certain area of ​​the cabinet 11. In this way, some heat exchange units 21 corresponding to the area can be opened and cooled in a centralized manner to reduce the loss of low-temperature gas.

[0049] It can be understood that the cooling system pipeline is also provided with cooling medium distribution components and cooling medium return components, which are respectively arranged at both ends of the plurality of heat exchange units 21 to divide and recycle the cooling medium of the heat exchange units 21 .

[0050] In some optional embodiments, there are multiple heat exchange coils 20, and multiple heat exchange coils 20 are arranged in parallel along the flow direction of the gas, and a second switch valve (not shown) is provided at one end of each heat exchange coil 20. In this way, one heat exchange coil 20 or multiple heat exchange coils 20 can be selected to cool the high-temperature gas according to the heat generation of the electronic equipment 12 in the cabinet 11, and the heat dissipation effect of the cabinet is better. Among them, each heat exchange coil 20 is provided with multiple heat exchange units 21 arranged in parallel.

[0051] The first switch valve 22 and the second switch valve can be of types well known to those skilled in the art, and this embodiment does not limit them.

[0052] In order to avoid cold loss when low-temperature gas circulates in the machine room, the heat exchange coil 20 in this embodiment is arranged on the air inlet side of the cabinet 10. In this way, the high-temperature gas is located in the machine room; the high-temperature gas is cooled by the heat exchange component on the air inlet side of the cabinet 11 to form low-temperature gas and enter the cold air zone 111 in the cabinet 11; the electronic equipment 12 drives the low-temperature gas to flow through itself to the hot air zone 112 on the air outlet side of the cabinet 11. When the low-temperature gas flows through the electronic equipment 12, the low-temperature gas exchanges heat with the high-temperature electronic equipment 12, the electronic equipment 12 cools down to achieve heat dissipation, and the low-temperature gas heats up to become high-temperature gas; the high-temperature gas is discharged into the machine room through the air outlet side of the cabinet 11.

[0053] The temperature inside the cabinet 11 in this embodiment is lower than the temperature outside the cabinet 11. Compared with the prior art, in which the low-temperature gas flows around the cabinet 11 inside the machine room to the air inlet side of the cabinet 11, the flow path of the low-temperature gas in this embodiment is limited to the inside of the cabinet 11, and the flow of the low-temperature gas becomes smaller, thereby avoiding the cold loss of the low-temperature gas when flowing inside the machine room, and the cooling effect is better.

[0054] Furthermore, the cold air zones 111 of two adjacent cabinets 11 are interconnected. In this way, the low-temperature gases of the two adjacent cabinets 11 can flow to each other. When the heat exchange component of one of the cabinets 11 cannot effectively dissipate heat due to a fault, the cabinet 11 can obtain low-temperature gases from the cold air zone 111 of the adjacent cabinet 11 for heat dissipation, thereby avoiding the problem that the local temperature of a cabinet 11 is too high, causing the electronic equipment 12 to malfunction.

[0055] In some optional embodiments, the cabinet system is further provided with a baffle (not shown) and a baffle driving member (not shown), the baffle being connected to the baffle driving member, the baffle being arranged at the connecting position between two adjacent cabinets 11, and the baffle driving member being able to drive the baffle to move so as to connect or disconnect two adjacent cabinets 11.

[0056] The baffle may be a plate-like structure, and the baffle is rotatably connected to the cabinet 11 or plugged into the cabinet 11, so that the baffle can rotate or move relative to the cabinet 11 to connect or disconnect two adjacent cabinets 11. It is understandable that the baffle may also be other structures well known to those skilled in the art, such as a shutter door.

[0057] Of course, in order to assist the failed cabinet 11 in dissipating heat, the adjacent cabinet 11 delivers low-temperature gas to the cold air zone 111 of the failed cabinet 11 through the opened baffle, and the adjacent cabinet 11 loses part of the low-temperature gas. Accordingly, the adjacent cabinet 11 can obtain more low-temperature gas by increasing the power of the heat exchange component to avoid the phenomenon of the temperature of the adjacent cabinet 11 also rising accordingly. For example, multiple heat exchange coils 20 can dissipate heat at the same time.

[0058] It can be understood that when a cabinet 10 adjacent to a faulty cabinet 10 is in a non-working state, the baffle of another cabinet 10 adjacent to the non-working cabinet 10 can be opened accordingly to allow the low-temperature gas to flow through the non-working cabinet 10 into the faulty cabinet 10.

[0059] In some optional embodiments, the electronic device 12 is provided with a temperature measuring element (not shown) for detecting the temperature of the electronic device 12 when it is working; the baffle is used to connect or disconnect two adjacent cabinets 11 according to the temperature measured by the temperature measuring element.

[0060] The temperature measuring element may be a thermometer or a temperature sensor, and the temperature measuring element is connected to the control system of the cabinet system, so that the control system can obtain the real-time temperature of the electronic equipment in the working state. At the same time, the driving element of the baffle is also electrically connected to the control system.

[0061] Then, when the electronic equipment 12 in a cabinet 11 is in working state, but the heat exchange component stops working due to a fault, the electronic equipment 12 cannot dissipate heat in time and the temperature rises, and the temperature measured by the temperature measuring component gradually rises. At this time, the control system can control the baffle on at least one side of the cabinet 11 to open, so as to introduce the low-temperature gas in the cold air zone 111 of the adjacent cabinet 11 into the cabinet 11, so as to avoid the temperature of the electronic equipment 12 being too high. At the same time, the alarm part in the cabinet 11 sounds an alarm to prompt the staff to repair the heat exchange component in the cabinet 11 in time.

[0062] Of course, the control system can also control the opening and closing degree of the damper, that is, the size of the cross-sectional area at the connection position of two adjacent cabinets 11, so as to adjust the flow rate of the circulating low-temperature gas according to the heat load of the failed cabinet 11. When the load of the failed cabinet 11 is small and the required low-temperature gas is small, the control system can control the damper to connect the two cabinets 11 with a small opening and closing degree, so that the failed cabinet 11 can obtain an appropriate amount of low-temperature gas, thereby avoiding the adjacent cabinet 11 from losing too much low-temperature gas.

[0063] According to the position of the cabinet 11 and the arrangement of the multiple cabinets 11, each cabinet 11 has at least one adjacent cabinet 11. For example, a cabinet 11 at an edge position has one adjacent cabinet 11. When multiple cabinets 11 are arranged in a certain direction, a cabinet 11 in the middle has two adjacent cabinets 11. Of course, when multiple cabinets 11 are stacked, the cabinet 11 in the middle can have three or more adjacent cabinets 11, which is not limited in this embodiment.

[0064] Considering that when a cooling system of a cabinet 10 fails, the flow capacity of the airflow inside the cabinet 10 becomes smaller, please refer to Figure 3 In some optional embodiments, the cabinet system is further provided with a first duct fan 13, which is arranged at the connecting position of two adjacent cabinets 11. The first duct fan 13 can rotate forward or reverse according to the temperature measured by the temperature measuring component, so that the cooled low-temperature gas can circulate between the two adjacent cabinets 11.

[0065] In this way, the first ducting fan 13 is controlled to rotate forward and reversely according to the relative position of the failed cabinet 10 and the first ducting fan 13. For example, if the failed cabinet 10 is located on one side of the first ducting fan 13, the first ducting fan 13 can be controlled to rotate forward to introduce the low-temperature gas in the cold air zone 111 of the adjacent cabinet 11 into the cabinet 11. Then, when the failed cabinet 10 is located on the other side of the first ducting fan 13, the first ducting fan 13 can be controlled to rotate reversely.

[0066] By setting the first fan 13, the control system can immediately start the first fan 13 when a cabinet 10 fails, thereby accelerating the flow of low-temperature gas and introducing an appropriate amount of low-temperature gas into the failed cabinet 10 in a shorter time, thereby avoiding the temperature of the failed cabinet 11 being too high.

[0067] It can be understood that the multiple cabinets 11 can be fixedly connected, that is, two adjacent cabinets 11 can share a side wall, and a connecting hole is provided on the side wall, so that the low-temperature gas between the two adjacent cabinets 11 can flow through the connecting hole.

[0068] Optionally, the cabinets 11 can be independent of each other. Correspondingly, the cabinet system further includes an air duct 14, the two ends of which are detachably connected to two adjacent cabinets 11, and an air outlet 114 connected to the air duct 14 is provided on the cabinet 11; and a baffle is arranged in the air duct 14.

[0069] The air duct 14 is a thin-walled cylindrical structure with a flow cavity inside, so that low-temperature gas can flow in the air duct 14. According to different arrangements of the cabinets 11, the air duct 14 can have different structures, such as a straight cylinder or a bent cylinder.

[0070] The air duct 14 is detachably connected to the cabinet 11, so as to facilitate disassembly, maintenance or replacement of the air duct 14 for each cabinet 10. It can be understood that a seal is provided at the connection position between the air duct 14 and the air outlet 114 to prevent low-temperature gas leakage and cold loss.

[0071] In some optional embodiments, the cabinet 11 further includes a filter (not shown), which is disposed at the air outlet 114 to filter the air flow introduced into the cabinet 11 .

[0072] The filter element may be a filter sponge or a filter net, etc., which are well known to those skilled in the art. The filter net is arranged at the air outlet 114 to prevent the airflow from carrying foreign matter into the cabinet 11. For example, when a cabinet 10 needs to be moved, the air guide 14 between the cabinet 10 and the adjacent cabinet 10 needs to be removed. At this time, a filter element is arranged on the air outlet 114 to prevent the internal space of the cabinet 10 from being directly exposed to the inside of the machine room through the air outlet 114.

[0073] Considering that a roller structure is usually provided at the bottom of the cabinet body 11 to facilitate the staff to move the cabinet 10, in some optional implementations, the air guide tube 14 is made of a flexible material.

[0074] In this way, when the staff moves multiple cabinets 10 at the same time, if two adjacent cabinets 10 move relative to each other, the air guide tube 14 can be correspondingly extended and deformed to prevent the air guide tube 14 from being broken due to pulling.

[0075] The air duct 14 may be a braided tube, a corrugated tube, etc., which are well known to those skilled in the art. The cross-sectional shape of the air duct 14 may be circular, rectangular, etc. Considering that the height of the cabinet 10 is relatively large, while the dimension of the air inlet side of the cabinet 11 along the air flow direction is relatively small, the height of the air duct 14 may be equivalent to the height of the cabinet 10, so as to increase the cross-sectional area of ​​the air duct 14, which helps more low-temperature gas to circulate between two adjacent cabinets 11.

[0076] In some optional embodiments, a second fan 15 is provided at the exhaust hole to guide the gas in the hot air area 112 of the cabinet 11 into the machine room.

[0077] Among them, when the second fan 15 is started, the air flow velocity can be increased, and the high-temperature gas on the discharge side of the cabinet 11 can be quickly and effectively discharged into the machine room. At the same time, the high-temperature gas in the hot air zone 112 is discharged, and the area is in a slightly negative pressure state, which can also help the low-temperature gas in the cold air zone 111 to replenish the hot air zone 112, that is, it helps the low-temperature gas flow and optimizes the heat dissipation effect.

[0078] The second ducting fan 15 can be of a type well known to those skilled in the art, and is not limited in this embodiment. For example, the second ducting fan 15 can be an EC (Electrical Commutation) fan, which can adjust the speed of the EC fan in real time according to the temperature measured by the temperature measuring element to prevent the temperature of the electronic device 12 from being too high.

[0079] The various embodiments or implementation methods in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referenced to each other.
