Description

TECHNICAL FIELD

[0001] The present application relates to the field of reinforced computer technology, for example to a control method for a heat dissipation rack and a heat dissipation rack. BACKGROUND

[0002] A rack server is a high-performance computer that provides computing or application services for other clients, and is generally composed of a rack (or a case), various functional LRM modules, etc. The LRM module has the advantages of on-site replaceability and strong interchangeability, and is the core of the server. The various functional LRM modules have high power consumption and generate a large amount of heat during operation, and thus the fans on the rack need to provide heat dissipation support. Therefore, heat dissipation design is also a crucial link that affects the overall performance of the server.

[0003] When engineers design heat dissipation, they usually find the optimal fan spatial layout when the server is fully loaded through a simulation method, fix the fan position, and divide the fan speed into 1-n gears. During server operation, the fans are in a fixed-point running state, and the selection of the fan gear is determined by human judgment. This leads to the following problems: 1) the fans are in a full running state, and if a slot of the rack is not loaded with a module, the air volume is lost; 2) if the rack is loaded with a single module or a plurality of modules, the heat dissipation flow field is affected by the number and loading position of the modules, and cannot achieve the optimal state; 3) the fan speed needs to be adjusted by humans, and there is a risk of improper gear selection affecting the heat dissipation effect.

[0035] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In combination with Figures 1-4 As shown in the drawings, the present disclosure provides a heat dissipation rack, which comprises a rack body, a fan, a wind channel state monitoring mechanism and a control mechanism.

[0037] The rack body comprises a mounting rack, a moving rack and a monitoring rack, the mounting rack is used for mounting the LRM module 17, the moving rack is provided with a moving mechanism, and the fan is movably installed on the rack body through the moving mechanism.

[0038] The fan is used for dissipating heat of the LRM module 17, and the fan and the rack body constitute a wind channel.

[0039] The wind channel state monitoring mechanism is installed on the monitoring rack and is used for monitoring the temperature and / or wind speed of the wind channel.

[0040] The position detection mechanism is used for detecting the installation position of the LRM module 17.

[0041] The control mechanism is electrically connected with the air duct state monitoring mechanism, the moving mechanism, the fan and the position detection mechanism, and the control mechanism is configured to control the moving mechanism to shift to drive the fan to move to adjust the heat dissipation flow field of the LRM module 17 according to the installation position of the LRM module 17 and the feedback data of the air duct state monitoring mechanism; the control mechanism is further configured to adjust the rotating speed of the fan to reduce the operating temperature when the heat dissipation flow field reaches the ideal state.

[0042] The position detection mechanism can be a weight sensor or a distance sensor installed on the mounting rack and used to detect whether the LRM module 17 is installed on the slot.

[0043] The heat dissipation rack provided by the embodiment of the present disclosure can automatically determine whether the corresponding fan operates according to whether the LRM module 17 is installed on the slot through the effective control of the control mechanism; the heat dissipation rack can automatically adjust the position of the fan according to the number and position of the LRM module 17 to make the heat dissipation flow field reach the optimal state; when the flow field reaches the optimal state, if the heat dissipation of the LRM module 17 still cannot reach the predetermined effect, the heat dissipation rack can automatically adjust the gear position of the fan to the appropriate rotating speed to reduce the operating temperature.

[0044] Optionally, the mounting rack is provided with a plurality of slots, and each slot is provided with a module guide rail 5 used for plugging and unplugging the LRM module 17, and the extension direction of the module guide rail 5 is perpendicular to the moving direction of the moving mechanism. The moving rack is located at the lower part of the mounting rack, and the monitoring rack is located at the upper part of the moving rack; each slot of the mounting rack is provided with a first through hole, and the monitoring rack is provided with a second through hole at the position corresponding to the slot, and each first through hole and second through hole cooperates to form an air duct, so that each slot corresponds to an air duct, and the air flows from bottom to top. The air duct state monitoring mechanism includes an air speed and temperature instrument 6 installed at the center of each air duct.

[0045] As an example, as shown in Figure 1 , 2 The heat dissipation rack includes nine slots, each slot corresponds to a module guide rail 5 and an air duct, and an air speed and temperature instrument 6 is installed at the center of each air duct. In the initial state, the fans are uniformly distributed as shown in Figure 1 The first fan 12, the second fan 14, the third fan 15 and the fourth fan 16 provide heat dissipation support for the first to second slots, the third to fifth slots, the sixth to seventh slots and the eighth to ninth slots, respectively. When the slot is empty, the fan providing heat dissipation for the slot is stationary; when the slot is loaded with the LRM module 17, the fan providing heat dissipation for the slot starts to operate.

[0046] Optionally, the moving mechanism is an electric guide rail assembly, and the electric guide rail assembly includes a rail body 10 and a sliding pressure piece 11, and the fan is connected with the sliding pressure piece 11, and the sliding pressure piece 11 can drive the fan to slide transversely along the electric guide rail 10.

[0047] Optionally, multiple fans are provided, and multiple sets of sliding pressure members 11 are provided, with each sliding pressure member 11 corresponding to a fan. The control mechanism adjusts the positions of multiple fans by adjusting the positions of the multiple sets of sliding pressure members 11, thereby changing the heat dissipation flow field of the LRM module 17. The controller includes a management board 8, which is used to receive and process information transmitted by the air duct status monitoring mechanism, fans, moving mechanism, and position detection mechanism. The frame also includes a rear panel 7, which has a cavity inside, and the management board 8 is installed in the cavity.

[0048] It is understandable that, such as Figure 1 , 2 As shown in Figure 3, the first fan 12, the second fan 14, the third fan 15, and the fourth fan 16 are fixed to the sliding pressure member 11 of the electric guide rail 10 by screws and nut plates 13. The management board 8 controls the sliding pressure member 11 to drive the fans to slide laterally along the electric guide rail 10 to find the fan position at the highest wind speed. After the anemometer 6 monitors the wind speed signal, it converts it into an electrical signal and transmits it to the management board 8. It continuously provides feedback to correct the fan position. When the maximum wind speed, i.e., the optimal wind field, is obtained, the voltage or current reaches an extreme value. After the fan position is adjusted, the wind speed reaches the maximum. If the temperature value monitored by the anemometer 6 is still greater than the set value t, the management board 8 controls the fan to continuously increase the speed until the monitored value is less than the set value t. This process is still a feedback correction process.

[0049] like Figure 4 As shown, taking the fan positions of slots four, five, and six equipped with LRM module 17 as an example, the first fan 12 and the fourth fan 16 are in a stationary state at this time. The management board 8 controls the second fan 14 and the third fan 15 to move to the position shown in the figure to obtain the maximum wind speed, i.e., the optimal flow field. If the temperature monitored by the anemometer 6 is still greater than the set temperature t, the management board 8 controls the fans to continuously increase their speed until the monitored value is less than the set value t.

[0050] This design method can also be used for racks with other numbers of slots. Using this design method, the rack can automatically determine the operation of the corresponding fan based on the number of LRM modules 17 installed in each slot.

[0051] In addition, the rack can automatically adjust the fan position according to the number and location of LRM modules 17 to achieve the optimal heat dissipation flow field. During use, the management board 8 can preset a first mapping table containing the mapping relationship between LRM module 17 mounting information and fan setting position. According to the mounting information and the first mapping table, the fan position is adjusted to achieve the optimal flow field. When the flow field reaches the optimal state, if the heat dissipation of module 17 still cannot achieve the predetermined effect, the rack can automatically adjust the fan speed to a suitable speed to reduce the operating temperature.

[0052] The above description and drawings suffice to fully enable one skilled in the art to practice the embodiments of the present disclosure. Other embodiments can include structural and other changes. The embodiments are merely representative of possible variations. Individual components and functions are optional unless explicitly required, and the order of operations can be varied. Portions and features of some embodiments can be included in, or substituted for, portions and features of other embodiments. The embodiments of the present disclosure are not limited to the mechanisms already described and shown in the drawings, and can be implemented in various modifications and changes, without departing from the scope thereof. The scope of the present disclosure is limited only by the claims appended hereto.
