[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention provides a server room with remote control function for liquid flow rate. The temperature of the server motherboard is detected by a temperature sensing module and converted into a signal by an A / D converter. The converted signal is sent to the remote control terminal through a second data transceiver module. When the temperature exceeds 45 degrees Celsius, the central processing unit sends a control command to the AMR microprocessor module through the control module.

When the telescopic cylinder retracts, the included angle between the two sets of adjusting rods decreases. At this time, the bearings of the two sets drive the limit rods of the two sets to move closer to each other. The movable shaft drives the swing rod to move, and the swing range of the other end of the swing rod increases. When the other end of the swing rod swings, it slides in the guide groove through the guide block, causing the sliding plate to move back and forth. When the sliding plate drives the valve plate to move back and forth inside the piston cylinder through the sliding rod, the coolant inside the heat sink is pumped into the heat conduction plate under the action of the one-way liquid inlet valve and the one-way liquid outlet valve, continuously cooling the circuit board and realizing the adjustment of heat dissipation speed.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To address the need for monitoring the internal temperature of servers during operation and ensuring stable operation, temperature detection and control present technical challenges when dealing with a large number of servers. Figures 1-4 As shown, the following preferred technical solutions are provided:

[0038] A server room with remote control function for liquid flow rate includes a control system 1 and a heat dissipation component 2. The control system 1 includes a remote control terminal 11 and a server control terminal 12 installed inside the server. The remote control terminal 11 can connect to several sets of server control terminals 12. The heat dissipation component 2 is also installed inside the server. The remote control terminal 11 includes a first data transceiver module 111, a central processing unit 112, a control module 113, and a data storage module 114. The first data transceiver module 111 is used to receive and transmit data from the server control terminal 12. The central processing unit 112 is used to process the temperature information sent by the server control terminal 12. The control module 113 is used to send control commands to the server control terminal 12. The data storage module 114 is used to store the received and transmitted control information.

[0039] The server control terminal 12 includes a second data transceiver module 121, an AMR microprocessor module 122, a temperature sensing module 123, and an A / D converter 124. The second data transceiver module 121 is used to transmit and receive data from the remote control terminal 11. The AMR microprocessor module 122 is used to process the signals and control commands sent by the remote control terminal 11. The temperature sensing module 123 is used to detect the temperature of the server motherboard. The A / D converter 124 is used to convert the current signal detected by the temperature sensing module 123 into a digital signal.

[0040] Specifically, the temperature of the server motherboard is detected by the temperature sensing module 123 and the signal is converted by the A / D converter 124. The converted signal is sent to the remote control terminal 11 through the second data transceiver module 121. When the temperature exceeds 45 degrees Celsius, the central processing unit 112 sends a control command to the AMR microprocessor module 122 through the control module 113. The AMR microprocessor module 122 controls the heat dissipation component 2 to dissipate heat from the server. When the temperature exceeds 65 degrees Celsius, the heat dissipation component 2 operates at overclock to dissipate heat.

[0041] To address the technical issues of controlling the server's heat dissipation rate, such as Figures 5-15 As shown, the following preferred technical solutions are provided:

[0042] The heat dissipation component 2 includes a server heat sink 21, a pump mechanism 22, a transmission mechanism 23, and a drive mechanism 24. A circuit board 3 is installed inside the server, and a heat conduction plate 31 is installed below the circuit board 3. The heat conduction plate 31 is hollow inside.

[0043] The outer surface of the heat sink 21 is evenly distributed with passive heat sinks 211, and the heat conduction plate 31 is connected to the upper interior of the heat sink 21 through the return pipe 32. The interior of the heat sink 21 is filled with coolant.

[0044] The pump mechanism 22 includes piston cylinders 221 installed on both sides in front of the heat sink 21. A one-way inlet valve 222 is installed on one side of the piston cylinder 221. A first inlet pipe 223 is installed on the outside of the one-way inlet valve 222, and the other end of the first inlet pipe 223 is connected to the lower interior of the heat sink 21. A second inlet pipe 33 is installed on one end of the heat conduction plate 31. A connecting pipe 35 is installed on the other end of the second inlet pipe 33 through a three-way pipe 34. A one-way outlet valve 36 is installed on the other end of the connecting pipe 35, and the other end of the one-way outlet valve 36 is connected to the interior of the piston cylinder 221.

[0045] A valve plate 224 is slidably connected inside the piston cylinder 221. A sealing ring 225 is provided on the outer edge of the valve plate 224. A sliding rod 226 is fixedly connected to the inner side of the valve plate 224. A sliding plate 227 is fixedly connected between the two sets of sliding rods 226. A fixed plate 229 is fixedly connected to the front of the heat sink 21. A transverse sliding groove 2291 is provided on the fixed plate 229. A slider 2271 is fixedly connected to the bottom of the sliding plate 227. The slider 2271 is slidably connected inside the sliding groove 2291. A guide plate 228 is fixedly connected to the top of the sliding plate 227. A longitudinal guide groove 2281 is provided on the inner side of the guide plate 228.

[0046] The transmission mechanism 23 includes fixed seats 231 fixedly connected to both sides of the heat sink 21. Rotating rods 232 are rotatably connected to each fixed seat 231. Transmission rollers 233 are fixedly connected to the inner side of each rotating rod 232. Connecting rods 234 are fixedly connected to the inner side of each transmission roller 233. Each connecting rod 234 is provided with a movable groove 2341. A limit rod 235 is slidably connected inside the movable groove 2341. An H-shaped plate 236 is rotatably connected to one end of each limit rod 235. A movable shaft 237 is rotatably connected between the two sets of H-shaped plates 236.

[0047] The outer surface of the movable shaft 237 is provided with a second rotating groove 2371. A bushing 238 is rotatably connected to the second rotating groove 2371. A fixing block 2381 is fixedly connected to the outer edge of the bushing 238. A rocker arm 239 is fixedly connected to the outer wall of the fixing block 2381. The other end of the rocker arm 239 is fixedly connected to the rotating shaft 2391 at both ends. The other end of the rotating shaft 2391 is fixedly connected to the guide block 2392. The guide block 2392 is slidably connected in the guide groove 2281 inside the guide plate 228. When the transmission roller 233 rotates, it drives the limiting rod 235 to rotate through the connecting rod 234. When the movable shaft 237 has a certain inclination, the limiting rod 235 rotates and drives the bushing 238 on the outer wall of the movable shaft 237, thereby causing the rocker arm 239 to swing left and right. When the rocker arm 239 swings left and right, the guide plate 228 can slide left and right through the rotating shaft 2391, thereby causing the valve plate 224 to reciprocate inside the piston cylinder 221.

[0048] A rotating plate 2351 is fixedly connected to the outer wall of the limiting rod 235, and a first rotating groove 2352 is arranged around the rotating plate 2351.

[0049] The drive mechanism 24 includes a dual-head motor 241 mounted on the top of the heat sink 21. Both output ends of the dual-head motor 241 are fixedly connected to the drive roller 242. A transmission belt 2421 is installed between the drive roller 242 and the transmission roller 233. When the dual-head motor 241 rotates, it can drive the transmission roller 233 to rotate through the drive roller 242 and the transmission belt 2421.

[0050] The drive mechanism 24 also includes a mounting base 243 fixedly connected to the top of the heat sink 21. A telescopic cylinder 244 is fixedly connected to the top of the mounting base 243. A first fixed frame 245 is fixedly connected to the output end of the telescopic cylinder 244. An adjusting rod 246 is rotatably connected to the front of the first fixed frame 245. Two sets of adjusting rods 246 are provided. The other end of each adjusting rod 246 is rotatably connected to a second fixed frame 247 via a rotating shaft 2461. A bearing 248 is fixedly connected to the other end of the second fixed frame 247. The bearing 248 is installed in the first rotating groove 2352 on the outer edge of the rotating plate 2351. When the telescopic cylinder 244 extends, the angle between the two sets of adjusting rods 246 opens, which increases the distance between the two sets of limiting rods 235, reduces the inclination of the movable shaft 237, and ultimately reduces the downward swing range of the swing arm 239, thereby reducing the pumping speed.

[0051] Specifically, when the temperature of circuit board 3 is too high and overclocking is required for heat dissipation, the telescopic cylinder 244 retracts, making the angle between the two sets of adjusting rods 246 smaller. At this time, the bearings 248 of the two sets drive the limit rods 235 of the two sets to move closer to each other. At this time, the inclination of the movable shaft 237 increases. When the dual-head motor 241 drives the transmission roller 233 to rotate, the movable shaft 237 drives the swing rod 239 to move. The swing range of the other end of the swing rod 239 increases. When the other end of the swing rod 239 swings, it slides in the guide groove 2281 through the guide block 2392, causing the sliding plate 227 to move back and forth. When the sliding plate 227 drives the valve plate 224 to move back and forth inside the piston cylinder 221 through the sliding rod 226, the coolant inside the heat sink 21 is pumped into the heat conduction plate 31 under the action of the one-way liquid inlet valve 222 and the one-way liquid outlet valve 36, continuously cooling the circuit board 3.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
