Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a panel assembly, a chassis and a server. Background Art

[0002] The server will emit a lot of heat during operation. Common heat dissipation methods include liquid cooling, air cooling, and combined cooling. In air-cooled servers, heat dissipation is generally achieved by blowing air to electronic components through a number of fans. The main principle is to drive the external low-temperature air flow through the fan to take away the heat inside the server. When the ambient temperature of the server is too high, the air inlet temperature will be higher than the chassis temperature. At this time, even if the fan rotates at full speed, it is still difficult to achieve effective cooling, which is likely to trigger a high temperature alarm, causing the server to shut down abnormally and give an error message.

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 are within the scope of protection of the present invention.

[0028] The features of the terms "first" and "second" in the specification and claims of the present invention may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the objects connected before and after are in an "or" relationship.

[0029] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected 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.

[0031] At present, with the rapid development of industrial upgrading and electronic information industry, all walks of life have higher and higher requirements for server performance and storage capacity. For example, in industries such as banking, IT, short video, and high-speed rail, the improvement of server computing performance has brought about an increase in power consumption, and the heat dissipation requirements are also getting higher and higher. If the heat dissipation is not timely, it will cause a series of problems such as server alarms, restarts, and even downtime. In order to ensure that the server can continue to operate in a better temperature environment, related technologies have proposed a variety of server cooling solutions. Among the many cooling solutions, heat exchange cooling is the most commonly used cooling solution, which transfers heat to the outside by blowing air from the front to the back.

[0032] When the ambient temperature of the server is too high, the air inlet temperature will be higher than the chassis temperature. At this time, it is difficult to effectively achieve cooling by fan operation alone. In the related technical scheme, cooling is achieved by the cooperation of fans and liquid cooling systems, that is, on the basis of air cooling, more coolant circulation flow paths are set in the chassis to achieve overall cooling. This method requires more flow paths and the overall layout structure is cumbersome, which makes it difficult to use and maintain, and has high maintenance costs. In addition, since this method uses the flow of liquid cooling to take away the heat from the corresponding position, it is difficult to solve the problem of local high temperature.

[0033] In the diagram, Figure 1 It is a schematic diagram of the three-dimensional structure of the panel assembly in the positive direction; Figure 2 It is a schematic diagram of the three-dimensional structure of the panel assembly facing backward; Figure 3 It is a schematic diagram of the matching structure of the telescopic mechanism and the locking component; Figure 7It is a schematic diagram of the three-dimensional structure of the panel assembly close to one end of the fixed block.

[0034] Regarding the problems in related technologies, such as Figure 1-Figure 3 As shown, the present invention provides a panel assembly, which includes a panel body 10, a liquid inlet pipeline 20 and a manifold 30, wherein the liquid inlet pipeline 20 is provided on the panel body 10 and arranged along the length direction of the panel body 10, and a plurality of spray holes are provided at the bottom of the liquid inlet pipeline 20, and the plurality of spray holes are arranged at intervals along the extension direction of the liquid inlet pipeline 20; the manifold 30 is provided on the panel body 10 and located below the liquid inlet pipeline 20, so that the coolant sprayed from each spray hole enters the manifold 30; wherein the panel body 10 is provided with a liquid inlet interface 21 and a liquid outlet interface 31, the liquid inlet interface 21 is connected to the liquid inlet pipeline 20, and the liquid outlet interface 31 is connected to the manifold 30. In the heat exchange refrigeration scheme, the size of the temperature difference often affects the cooling effect. In this embodiment, the coolant can be sprayed out through the spray holes on the liquid inlet pipe 20, thereby forming a curtain-like liquid cooling area between the liquid inlet pipe 20 and the collecting tank 30, so that even if the external ambient temperature is high, the wind entering the server can be cooled, achieving a good cooling effect.

[0035] Specifically, the panel body 10 is extended along its length direction to form two ends, extended along its thickness direction to form two sides, and extended along its height direction to form two sides. The extension distance in the length direction is greater than the extension distances in the height direction and the thickness direction, and the extension distance in the thickness direction is smaller than the extension distance in the width direction, thereby forming a flat rectangular structure as a whole.

[0036] like Figure 1 As shown, the panel body 10 is a rectangular block structure, and the liquid inlet pipe 20 is arranged on the panel body 10. There is a certain distance between the liquid inlet pipe 20 and the collecting tank 30 in the height direction, so that the coolant in the liquid inlet pipe 20 can flow from the spray hole to the collecting tank 30, so that the coolant flowing between the liquid inlet pipe 20 and the collecting tank 30 forms a curtain-like cooling area.

[0037] It is understandable that when the temperature of the external environment is higher than the temperature of the internal environment, the wind needs to pass through the curtain-shaped cooling area between the liquid inlet pipeline 20 and the manifold 30 to enter the server. When the wind passes through the cooling area, it will cause water mist and relatively more humid air, thereby reducing the temperature at the air inlet. The reduced wind enters the server, thereby providing comprehensive heat exchange and achieving efficient cooling.

[0038] Compared with the method of setting a flow channel in the chassis 90 in the related art, this embodiment adopts an effective combination of air cooling and liquid cooling to reduce the temperature. That is, it combines the wide coverage area, simple maintenance and low cost of air cooling with the superior heat dissipation performance and high space utilization of liquid cooling, thereby achieving low-cost and efficient cooling.

[0039] like Figure 1 , Figure 7 As shown, a molding 13 is formed on the outer surface of the panel body 10, and corresponding molding surfaces 131 are provided on opposite sides of the molding 13, and a flow channel is constructed in the molding surface 131. There is a certain distance between the two molding surfaces 131, and the two molding surfaces 131 are respectively close to the two ends of the panel body 10, so that a space for arranging the liquid inlet pipeline 20 is formed between the two molding ends, and the two ends of the liquid inlet pipeline 20 are connected to the respective corresponding molding surfaces 131, and the liquid inlet pipeline 20 is supported by the molding surfaces 131. When the coolant flows, the coolant is input through the liquid inlet interface 21, and the coolant is input into the liquid inlet pipeline 20 through the flow channel in the molding surface 131, completing the input of the coolant.

[0040] In specific settings, such as Figure 7 As shown, the molded part 13 and the panel body 10 are welded by hot melt, and a flow channel structure is integrally formed in the portion where the molding surface 131 is located. The two ends of the tube body of the liquid inlet pipeline 20 are inserted into the flow channel openings of the corresponding molding surface 131, and the liquid inlet pipeline 20 is connected by hot melt welding. Of course, in other settings, the liquid inlet pipeline 20 can also be directly molded and set between the two molding surfaces 131. In this embodiment, the tube body of the liquid inlet pipeline 20 is connected by hot melt welding. This method reduces the overall molding difficulty and is conducive to the maintenance of the liquid inlet pipeline 20 in the later stage.

[0041] like Figure 1 As shown, both the liquid inlet interface 21 and the liquid outlet interface 31 are connected with pipeline joints, which protrude from the outer surface of the outer side of the molded part 13. The protruding part can be easily connected to the pipeline of the external cooling system to achieve quick connection.

[0042] The external cooling system includes a pipeline system and a liquid cooling device. The liquid cooling device is used to cool the coolant. The pipeline system includes a liquid outlet pipeline and a liquid inlet pipeline 20. One end of the liquid inlet pipeline 20 is connected to the liquid inlet interface 21, and the other end of the liquid inlet pipeline 20 is connected to the output port of the liquid cooling device. One end of the liquid outlet pipeline is connected to the liquid outlet interface 31, and the other end of the liquid outlet pipeline is connected to the input port of the liquid cooling device. In this way, the cooling can be cooled after the external circulation, and the coolant can be fully utilized.

[0043] Specifically, the coolant can be cooling water, ethylene glycol solution, etc., and water is used as the coolant for exemplary description in this embodiment. The header 30 is located below the liquid inlet channel, and the cooling water entering the liquid inlet channel can be sprayed out from the spray hole and sprayed into the header 30 accordingly, and recycled through the header 30 and the external cooling system.

[0044] It should be noted that, as needed, the coolant can be pressurized and input into the liquid inlet pipe 20, that is, the coolant entering the liquid inlet pipe 20 is a pressurized liquid. Correspondingly, in order to prevent the liquid entering the collecting tank 30 from splashing out, the depth of the collecting tank 30 can be deepened or a flexible pad can be added. The pressurized coolant flows faster, which can achieve efficient circulation of the coolant, thereby achieving efficient cooling.

[0045] Furthermore, an anti-splashing layer is provided on the bottom surface of the collecting tank 30, and the anti-splashing layer can be a flexible pad made of a flexible material, or a flexible layer can be directly coated on the bottom of the collecting tank 30 to prevent liquid from splashing. Among them, the flexible pad can be a mesh structure to enhance the anti-splashing effect.

[0046] In some embodiments, Figure 2 As shown, the end surfaces at both ends of the panel body 10 are provided with connecting parts 50, and the connecting parts 50 are used for the detachable connection of the panel body 10. The panel body 10 needs to be installed on a chassis 90, a cabinet or other main equipment to play a role in reducing the temperature of the air inlet. In this embodiment, by providing the connecting parts 50 on the two ends of the panel body 10, the detachable connection of the panel body 10 is realized, so that the panel body 10 can be quickly disassembled and assembled.

[0047] Generally speaking, the panel body 10 needs to be installed on other main equipment. The panel body 10 in this embodiment can directly realize cooling at the air inlet, so as to reduce the temperature of the wind entering the main equipment, effectively reduce the internal temperature, and avoid the problem of local high temperature in the main equipment. Through the connection parts 50 on both ends of the panel body 10, it can realize the detachable connection of the panel body 10, which is convenient for the disassembly and assembly of the panel body 10.

[0048] Specifically, the connection part 50 is used to detachably connect the panel body 10 to the server, chassis 90 or main device, so as to achieve cooling at the air inlet. In a specific implementation, the connection part 50 can be a bolt connection block, which is fixedly connected to both ends of the panel body 10, and the panel body 10 is fixed to the device by bolts. The bolt fixing method can facilitate disassembly and assembly, and can achieve a relatively stable connection strength. Of course, the existing detachable connection method can be used to achieve the detachable connection of the panel body 10, for example, magnetic connection, snap connection, hinge connection, etc.

[0049] In some embodiments, the connection portion 50 includes a fixed block 52 and a telescopic block 51, wherein the fixed block 52 is fixedly disposed at one end of the panel body 10, and the telescopic block 51 is disposed at the other end of the panel body 10 through a telescopic mechanism 60. The connection of the panel body 10 needs to take into account both the stability of the connection and the convenience of disassembly. In this embodiment, one end is provided as the fixed block 52 and the other end is provided as the telescopic block 51, so that both stability and convenience can be achieved.

[0050] Both ends of the panel body 10 are provided with a connecting portion 50 of a columnar structure body, so that when installing the panel body 10, both ends of the panel body 10 need a columnar structure fixed block 52 or a telescopic block 51 to achieve support, which can make the panel body 10 more stable after being installed on the device. And one of them is set as a telescopic block 51, and the telescopic operation of the telescopic block 51 is realized by means of a telescopic mechanism 60, so as to facilitate the disassembly and assembly of the panel body 10.

[0051] For example, matching grooves are provided on both sides of the air inlet of the chassis 90 or the main device. During installation, the fixing block 52 is first inserted into the corresponding matching groove, and the end is fitted with the side wall of the air inlet. Then, the telescopic block 51 is driven to retract so that the end with one end of the telescopic block 51 is located on the other side opposite to the air inlet. Then, the panel body 10 is installed by extending the telescopic block 51 and inserting the telescopic block 51 into the matching groove, thereby improving the stability of the overall installation.

[0052] In the specific setting, the number of fixed blocks 52 and telescopic blocks 51 can be multiple, and multiple fixed blocks 52 are arranged on the end surface of one end of the panel body 10, and multiple telescopic blocks 51 are arranged on the end surface of the other end of the panel body 10. In this way, the stability of the installation of the panel body 10 can be further improved.

[0053] For example, Figure 1 , Figure 2 As shown, there are two fixed blocks 52 and two telescopic blocks 51, and the two fixed blocks 52 and two telescopic blocks 51 are spaced apart near the upper and lower sides of the panel body 10. The arrangement of the two fixed blocks 52 and two telescopic blocks 51 can further facilitate installation and ensure the stability of the overall connection.

[0054] In some embodiments, the fixing block 52 may be a protruding structure directly connected to one end of the panel body 10, which facilitates the overall construction. By directly forming the fixing block 52 on the end surface of one end of the panel body 10, the fixing block 52 has a higher structural strength, making the panel more stable after connection.

[0055] In some embodiments, Figure 3As shown, the telescopic mechanism 60 includes a support plate 61 and a main body plate 62, wherein the support plate 61 is fixedly connected to the panel main body 10, and the main body plate 62 is slidably arranged on the support plate 61; wherein, a claw portion is formed on one side of the main body plate 62, and a part of the claw portion is located outside the end face of the panel main body 10 to form a telescopic block 51; and a connecting column 623 for connecting the elastic component 63 is formed on the other side of the main body plate 62. The telescopic block 51 is used to realize the movement of the telescopic block 51 by driving its telescopic mechanism 60 during disassembly and assembly, thereby facilitating disassembly and assembly. In this embodiment, the support plate 61 can provide support for the main body plate 62, the support plate 61 is fixedly connected to the panel main body 10, and the main body plate 62 can slide relative to the support plate 61, thereby realizing the adjustment of the extension amount of the claw portion, which is conducive to the overall disassembly and assembly.

[0056] like Figure 4 , Figure 5 As shown, the main body plate 62 is constructed as a "Y"-shaped structure, and two free protruding ends are formed on one side, and the two free protruding ends each form the claw portion. A through hole is correspondingly opened on the end of the panel body 10, and the distal end of the claw portion protrudes to the outside of the panel body 10 through the through hole to form a telescopic block 51. That is, in this embodiment, the part of the claw portion extending from the through hole at the end of the panel is named as the telescopic block 51, and the telescopic block 51 can be retracted into the through hole driven by the entire main body plate 62 to facilitate the quick disassembly and assembly of the whole.

[0057] Specifically, the main plate 62 is slidably connected to the support plate 61 through a sliding structure, and the sliding structure includes a plurality of strip-shaped through holes 624 provided on the main plate 62, and screw columns provided in the strip-shaped through holes 624, the screw columns are fixedly connected to the support plate 61, and extend vertically through the strip-shaped through holes 624. A gasket or a nut or other component may be connected to the top of the screw column, so that the main plate 62 is located on the screw column and can be limited by the screw column when moving, so that the main plate 62 can move along the direction in which the strip-shaped holes are opened, that is, move in the left and right directions in the figure.

[0058] For example, Figure 3 , Figure 4 As shown, a strip-shaped through hole 624 is provided on the main body of the main plate 62 near the claw part and on the main body on one side of the connecting column 623. The three strip-shaped through holes 624 are arranged in parallel, and a screw column is arranged in each strip-shaped through hole 624, and the screw column is used to limit the freedom of the main plate 62 in the vertical direction. The elastic component 63 is a spring, and connecting columns 623 are respectively arranged at the bifurcated positions of the two claw parts of the main plate 62. One end of the spring is connected to the connecting column 623, and the other end of the spring abuts against the support plate 61, thereby realizing the reset operation of the main plate 62.

[0059] In the specific setting, the support plate 61 is also constructed as a "Y"-shaped structure as a whole, and an abutment plate is formed at one end of the support plate 61, and the abutment plate is used to abut with the elastic component 63, so that the spring can be compressed when the main plate 62 moves relative to the support plate 61, and when the telescopic block 51 is finally located in the matching groove, the final clamping can be achieved under the action of the spring.

[0060] In some embodiments, the panel body 10 is further provided with a locking member 70, which can selectively abut against the telescopic mechanism 60 to open or close the telescopic function of the telescopic mechanism 60. The arrangement of the locking member 70 can make the panel body more secure after installation and has an anti-theft effect.

[0061] Generally speaking, after the panel body 10 is arranged on the main device or chassis 90 through a detachable connection structure, anyone can disassemble the panel body 10 through the detachable structure, which makes the panel body 10 easy to be stolen, resulting in a high security risk. As can be seen from the above, one end of the panel body 10 is efficiently disassembled through the telescopic block 51. At the same time, due to the telescopic characteristics of the telescopic block 51, the stability and anti-theft performance are relatively weak. In this embodiment, the locking component 70 is set, so that it can be locked by the locking component 70 after the clamping is completed, thereby improving the stability of the overall installation, and can achieve anti-theft through the setting of the locking component 70, thereby improving its security performance.

[0062] In a specific implementation, the main plate 62 has a raised limiting portion 621, one end of the limiting portion 621 has a limiting end face 625, and the locking member 70 can abut against the limiting end face 625, thereby preventing the main plate 62 from moving and achieving the effect of locking the main plate 62. By setting the main plate 62 to lock, the overall stability and safety can be improved.

[0063] like Figure 1 , Figure 3 As shown, the locking component 70 includes a lock body 71 and an abutment portion 73. The abutment portion 73 is connected to the lock body 71. A lock core 72 is provided in the lock body 71. The abutment portion 73 can be rotated by inserting a key outside the lock core 72, so that the abutment portion 73 switches between the abutment position and the free position.

[0064] When in the abutting position, the abutting portion 73 abuts against the limiting end surface 625 to limit the movement of the main plate 62. When in the free position, the abutting portion 73 is disengaged from the abutting and is located on one side of the limiting portion 621, so that the main plate 62 can move freely left and right.

[0065] In some embodiments, a first handle block 622 is formed on the limiting portion 621, one end face of the first handle block 622 is coplanar with an end face of the limiting portion 621, and a protruding edge structure 626 is provided on the face to form a first handle area 627. The first handle area 627 is convenient for fingers to hold when moving the panel body 10, which is conducive to holding and carrying.

[0066] like Figure 2 , Figure 8 As shown, a fixing plate 80 is provided at the end of the panel body 10 opposite to the end with the telescopic block 51. The fixing plate 80 is integrally constructed as a "Y"-shaped structure. The fixing plate 80 is fixedly connected to the panel body 10, and the fixing plate 80 is also formed with two fixing claws. A through hole is provided on the corresponding end face of the panel body 10, and the fixing claw extends through the through hole, and the fixing block 52 is connected to the fixing claw and is located outside the through hole. Specifically, the fixing block 52 is integrally formed with the fixing claw, so that the part of the fixing claw located outside the through hole is the fixing block 52. Arranging in this way can make the structural stability of the fixing block 52 higher.

[0067] In the specific configuration, a second buckle block is formed on the fixing plate 80, and an end surface of the second buckle block 81 is provided with an outwardly protruding edge structure 626 to form a second buckle area 811. The first buckle area 627 and the second buckle area 811 are respectively located near the left and right ends of the panel, so that the first buckle area 627 is formed on the left side of the panel body 10, and the second buckle area 811 is formed on the right side of the panel body 10. The buckle areas at both ends are convenient for fingers to hold during transportation.

[0068] In some embodiments, Figure 1 , Figure 2 , Figure 6 , Figure 7As shown, the panel assembly also includes a protective structure, which is installed on the panel body 10; the protective structure includes a filter plate 42, and a protective net 41 is provided on the front and back of the filter plate 42; wherein the filter plate 42 forms a ventilation gap, and the protective net 41 forms a grid-like main structure, and the top edge and bottom edge of the filter plate 42 are both provided with a plurality of bayonet holes, and the plurality of bayonet holes are arranged at intervals along the length direction of the filter plate 42, and a matching notch is provided on the protective net 41 at the corresponding position of each bayonet hole, and the matching notch and the bayonet hole correspond to form a through-connecting slot 43; the panel body 1 0 comprises a main frame, a top plate 11 is provided at the top of the main frame, a bottom plate 12 is provided at the bottom of the main frame, a first clamping protrusion group is provided on the top plate 11 corresponding to the top clamping slot 43, and a second clamping protrusion group is provided on the bottom plate 12 corresponding to the bottom clamping slot 43; the first clamping protrusion group comprises a plurality of first clamping protrusions, and the plurality of first clamping protrusions are clamped with the top clamping slot 43 in a one-to-one correspondence; the second clamping protrusion group comprises a plurality of second clamping protrusions, and the plurality of second clamping protrusions are clamped with the bottom clamping slot 43 in a one-to-one correspondence, so as to realize the clamping installation of the filter plate 42 and the protective net 41. It can be seen from the aforementioned embodiments that the overall solution realizes cooling of the air inlet by forming a water curtain or a coolant curtain-like structure. This method will generate water mist during cooling. When the cooling air enters the main device or the chassis 90, the water mist may be brought into the interior. In this embodiment, the filter plate 42 can absorb the water mist to prevent the water mist and fine particles such as dust from entering the main device or the chassis 90, thereby improving the service life of the main device or the chassis 90.

[0069] Specifically, if Figure 6 As shown, the protective structure includes two protective nets 41, and a filter plate 42 is arranged between the two protective nets 41. The filter plate 42 can filter fine particles and water mist, and can effectively cool the incoming air to increase the service life of the device host. For example, the filter plate 42 can be an activated carbon plate with gaps, or a polyester fiber board, or a plastic plate with gaps, or a sponge plate with gaps, etc.

[0070] It is understandable that water with a natural flow of the spray hole enters the collecting tank 30, thereby forming a water curtain, and the water curtain realizes cooling of the incoming air during the continuous circulation process. In this embodiment, the water mist is absorbed by the filter plate 42 at the rear, and the absorption temperature will increase under the action of the high-temperature external environment when absorbed by the filter plate 42, so that the filter plate 42 forms a cooling structure, and the incoming air enters through the ventilation gap of the filter plate 42, increasing the contact area between the wind and the filter plate 42, thereby realizing efficient heat exchange, improving the cooling efficiency of the incoming air, and realizing efficient cooling of the incoming air.

[0071] Generally speaking, the filter plate 42 will absorb a large amount of dust in the long term, which requires replacement or cleaning after a certain period of time. When replacing or cleaning, the protective assembly 40 needs to be disassembled. In this embodiment, the structure of the card slot 43 and the card-connecting protrusion is formed to facilitate quick disassembly and reduce the difficulty and cost of later maintenance.

[0072] In some embodiments, both ends of the liquid inlet pipeline 20 are provided with liquid inlet interfaces 21; both ends of the manifold 30 are provided with liquid outlet interfaces 31. The liquid inlet interface 21 is used to input the circulating coolant, and the liquid outlet interface 31 is used to output the circulating coolant. In this embodiment, by providing the liquid inlet interfaces 21 on both sides of the liquid inlet pipeline 20, two cooling systems can be connected during connection to achieve efficient circulation of the coolant.

[0073] Specifically, the entire liquid inlet pipeline 20 and the manifold 30 have a certain length. When the two liquid inlet interfaces 21 simultaneously input the coolant, all the through holes on the liquid inlet pipeline 20 can have a water line (water in each spray hole continuously falls to form a "line"-shaped structure, such as Figure 1 , Figure 6 The cylindrical shape between the liquid inlet pipe 20 and the manifold 30 represents the water line), thereby avoiding the situation that the coolant may not reach the spray hole position at the other end due to the input of coolant at one end. The two liquid outlet interfaces 31 can discharge the water in the manifold 30 in time to avoid deposition in the manifold 30. In addition, by setting the two liquid outlet interfaces 31 and the two liquid inlet interfaces 21, when one of them is blocked or damaged, the other side can still be used, thereby improving the applicability of the panel assembly.

[0074] In specific configuration, the liquid inlet interface 21 and the liquid outlet interface 31 close to the same side are spaced apart, the liquid inlet interface 21 is located at the upper part of the panel body 10 , and the liquid outlet interface 31 is located at the lower part of the panel body 10 .

[0075] In some embodiments, the liquid inlet pipeline 20 is arranged in parallel with the manifold 30, and the spray hole is located directly above the manifold 30. The parallel arrangement can fully utilize the overall space, making the structure in the panel assembly more compact.

[0076] Generally speaking, the cooling liquid can flow out from the spray hole after entering through the liquid inlet pipe 20. In this embodiment, the collecting tank 30 is located directly below the spray hole, which can make the overall structure more compact, facilitate the overall layout, and make the thickness of the panel body 10 thinner.

[0077] like Fig. 9As shown, the present invention also provides a chassis 90, which includes a box body and the panel assembly as described above; a panel window is provided on one side of the box body, and a plurality of ventilation channels are provided at intervals at the panel window, and both sides of the panel window are provided with limit ears 91, and the panel assembly can be detachably installed between the limit ears 91 on both sides. The panel assembly is provided at the air inlet of the box body, and is detachably connected to the limit ears 91 on both sides of the air inlet, thereby realizing quick installation of the panel assembly.

[0078] Generally speaking, the chassis 90 has a ventilating opening. In this embodiment, the panel window is located at the ventilating opening, and ventilation can be achieved through the ventilating opening at the panel window. The panel assembly is arranged on the panel window to cool the wind entering the inside of the chassis 90, thereby achieving the purpose of cooling the inside of the chassis 90.

[0079] In the specific configuration, the side walls opposite to the two limiting ears 91 are provided with a snap-fitting notch 911, and the fixing block 52 and the telescopic block 51 can be inserted into the snap-fitting notch 911, so that the panel assembly can be inserted and snap-fitted. That is, during installation, the fixing blocks 52 and the telescopic blocks 51 at both ends of the panel assembly are aligned with the snap-fitting notches 911 on one side thereof, so as to realize the snap-fitting of the panel assembly.

[0080] In some embodiments, a main BMC module and a backup BMC module are provided in the box; a temperature sensor 912 is provided on at least one side of the limit lug 91, and the temperature sensor 912 is electrically connected to the main BMC module and the backup BMC module respectively. The temperature sensor 912 can detect the temperature of the external environment and the internal environment, and input the collected data into the main BMC module and the backup BMC module, thereby providing a corresponding cooling strategy to achieve efficient cooling inside the box.

[0081] The BMC module is the abbreviation of the baseboard management controller module (BASE MANAGEMENT CONTROLLER), which can output instructions based on the feedback of the collected signals to control whether the water cooling system in the panel components is turned on.

[0082] When the temperature sensor 912 detects that the external temperature is higher than the internal temperature, the BMC module can issue a command to make the fan rotate at full speed to achieve a large amount of air intake, and at the same time turn on the liquid cooling system so that the incoming air can be effectively cooled through the panel assembly. When the temperature sensor 912 detects that the external temperature is lower than the internal temperature, the strategy at this time is to directly turn on the fan to achieve internal cooling.

[0083] In this embodiment, a main BMC module and a backup BMC module are provided. By designing the backup BMC module, when the main BMC module fails or is abnormal, the system can be switched to the backup module in time to ensure the normal operation of the system and improve the reliability of the system. The design of the backup BMC module can simplify maintenance operations and reduce downtime. When the main BMC module fails, the system can be quickly switched to the backup module without shutting down the entire system for maintenance, thereby improving the availability of the system.

As long as the chassis 90 is provided with the above-mentioned panel assembly, it should fall within the description scope of this embodiment; the chassis 90 should have all the beneficial effects of the above-mentioned panel assembly, which will not be repeated here one by one.

[0085] The present invention further provides a server, the server comprising the panel assembly as described above, or the server comprising the chassis 90 as described above.

[0086] In a specific embodiment, the server includes a box, a mainboard and a panel assembly. The mainboard is installed in the box, and the panel assembly is snapped into the vent of the box so that the air duct of the air intake is arranged opposite to the panel assembly. At the same time, limit ears 91 are provided on both sides of the same vent for snapping with the panel assembly.

[0087] In another specific embodiment, the server includes a box, a mainboard and a panel assembly. The mainboard is installed in the box. Limiting ears 91 are provided on both sides of the vent of the box. The panel assembly is snap-connected with the limiting ears 91 at the vent position.
