[0046] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] The present invention provides Figure 1-Figure 10 A liquid cooling heat sink with a water nozzle structure shown in the figure comprises a heat sink body 1 and an assembly 2, a monitoring mechanism 3 is provided on the rear side of the heat sink body 1, and a micro servo motor 4 and a controller 5 are provided on one side of the assembly 2;

[0048] An arc-shaped water channel is provided in the heat sink body 1, and a plurality of symmetrically arranged circular openings are provided on one side of the water channel, and a conducting mechanism 11 is sealed and rotatably connected in each of the plurality of circular openings;

[0049] One end of the two conducting mechanisms 11 is electrically connected to the monitoring mechanism 3;

[0050] The transmission mechanism 11 includes a transmission rod 111, which is rotatably connected in a circular opening. One end of the transmission rod 111 is connected to an arc-shaped blade 112, and the other end of the transmission rod 111 is connected to a disk 113. The outer wall of the disk 113 is provided with a plurality of metal contacts 114 arranged in a ring shape, and two adjacent symmetrically arranged metal contacts 114 are connected by a metal wire 115. This design of the transmission mechanism 11 can accurately sense changes in water flow. When there is water flow, the arc-shaped blade 112 is impacted by the water flow and drives the transmission rod 111 to rotate, thereby rotating the disk 113, and the metal contacts 114 on the disk 113 move accordingly, converting the tiny movement of the water flow into changes in electrical signals, providing a reliable basis for water leakage monitoring and improving the sensitivity of water leakage detection.

[0051] The monitoring mechanism 3 includes a protective cover 31, which is connected to the bottom of the heat sink body 1. A plurality of mounting plates 32 are installed in the protective cover 31. A ring base 33 is provided on the top of the mounting plate 32. Both ends of the ring base 33 are provided with power supply slots. A plug matching the slot is inserted into the slot. The plug is electrically connected to the controller 5 through a wire. A plurality of metal conductive sheets 34 matching the metal contacts 114 are provided in the ring base 33. The plurality of metal conductive sheets 34 are arranged in a ring shape.

[0052] The assembly 2 is connected to the water nozzle at the input end of the heat sink body 1. A flow control mechanism 21 is provided in the assembly 2, and the flow control mechanism 21 is connected to the water nozzle at the input end of the heat sink body 1.

[0053] The micro servo motor 4 is electrically connected to the controller 5, and the power output shaft of the micro servo motor 4 is transmission-connected to the flow control mechanism 21. One end of the controller 5 is connected to the first temperature sensing probe 6 through a wire, and the detection end of the first temperature sensing probe 6 is plugged into the output end water nozzle of the heat sink body 1. The other end of the controller 5 is connected to the flow rate monitoring component 7 through a wire, and the flow rate monitoring component 7 is connected to the input end water nozzle of the heat sink body 1.

[0054] In the above, through the setting of the above structure, the water flow velocity, temperature monitoring and flow control of the liquid-cooled heat sink can be realized. The rotating turbine 73 in the flow velocity monitoring component 7 rotates under the impact of the water flow, and the speed data collector 72 collects its speed data and transmits it to the controller 5 through the transmission wire to realize water flow velocity monitoring. The first temperature sensing probe 6 detects the temperature of the water nozzle at the output end, and the micro servo motor 4 drives the flow control mechanism 21, which can adjust the flow as needed to ensure the stable and efficient operation of the heat dissipation system, effectively improve the heat dissipation efficiency, and ensure the normal operation of the equipment.

[0055] Furthermore, the flow control mechanism 21 includes an adjusting rod 211, which is rotatably connected in the assembly 2, and a spherical valve 212 is connected to the adjusting rod 211. One end of the adjusting rod 211 is connected to a conical gear disk 213, and the conical gear disk 213 is meshed with a conical gear 214, and the conical gear 214 is connected to the power output shaft of the micro servo motor 4.

[0056] In the above, the micro servo motor 4 can drive the bevel gear 214 to rotate, drive the bevel gear disc 213 meshing with it to rotate, and then rotate the adjustment rod 211 to achieve precise adjustment of the water flow. The flow rate can be controlled according to system requirements to meet the heat dissipation requirements under different working conditions, and improve the adaptability and reliability of the heat dissipation system.

[0057] Furthermore, the spherical valve 212 is provided with an opening in an arc-shaped recessed shape.

[0058] In the above, the special opening design of the ball valve 212 helps to control the water flow more flexibly. By rotating the ball valve 212, the relative position of the opening and the water flow channel is changed, thereby changing the cross-sectional area of ​​the water flow, optimizing the flow control effect, and further improving the performance of the heat sink.

[0059] Furthermore, the flow rate monitoring component 7 includes a hollow metal rod 71, which is connected to the inner wall of the water nozzle at the input end of the heat sink body 1. A transmission wire is provided inside the hollow metal rod 71. A speed data collector 72 is connected to the hollow metal rod 71. The speed data collector 72 is connected to the controller 5 through the transmission wire. A rotating turbine 73 is rotatably connected to the speed data collector 72.

[0060] In the above, when water flows through the water nozzle at the input end, it impacts the rotating turbine 73 to make it rotate. The speed data collector 72 collects the speed information of the rotating turbine 73, and transmits the data to the controller 5 through the transmission wire in the hollow metal rod 71, so that the water flow speed can be accurately measured, providing key data for flow control and system operation status evaluation, facilitating timely adjustment of system parameters, and ensuring stable operation of the cooling system.

[0061] Furthermore, a sealing cover plate is provided on the top of the annular base 33 .

[0062] In the above, the sealing cover can prevent external factors from interfering with the circuit connection and signal transmission inside the monitoring mechanism 3. It can prevent dust, water vapor and other impurities from entering the annular base 33, avoid affecting the contact between the metal contact 114 and the metal conductive sheet 34, and ensure the stability and accuracy of the monitoring function.

[0063] Furthermore, a second temperature sensing probe 8 is provided in the monitoring mechanism 3, and one end of the second temperature sensing probe 8 extends into the water channel.

[0064] In the above, the second temperature sensing probe 8 is in direct contact with the coolant in the water channel, and can obtain the coolant temperature information in real time. Cooperating with the first temperature sensing probe 6, it can more comprehensively grasp the temperature of the cooling system, provide more basis for system control and fault warning, and ensure the safe and stable operation of the cooling system.

[0065] Furthermore, both sides of the assembly 2 are provided with mounting strips plugged into the heat sink body 1 .

[0066] In the above, the mounting strip is designed to facilitate the installation and removal of the assembly 2 and the heat sink body 1. When installing, the mounting strip is inserted into the corresponding slot of the heat sink body 1 to complete the fixation;

[0067] In the above, when disassembling, the installation strip can be pulled out to separate, which is convenient for maintenance and repair of the equipment and improves the convenience of using the equipment.

[0068] Working principle:

[0069] 1. Water flows in from the water nozzle at the input end. When the water flows, the rotating turbine 73 is driven to rotate. The rotation speed data is collected by the rotation speed data collector 72, and the data is transmitted to the controller 5 through the transmission wire in the hollow metal rod 71. The controller 5 collects the data and monitors the water flow speed of the water nozzle at the input end.

[0070] When the water flow rate needs to be controlled, the micro servo motor 4 can be driven by the controller 5, and the micro servo motor 4 drives the bevel gear 214 to rotate, and drives the bevel gear plate 213, the adjustment rod 211 and the ball valve 212 to rotate, and the water flow rate of the input end water nozzle can be controlled by the rotation of the ball valve 212;

[0071] When the water flows in the water channel, the temperature in the water channel is monitored by the second temperature sensing probe 8;

[0072] 2. When the water flow is shut off by the flow control mechanism 21, the water flow in the waterway stops flowing, and the cooperation between the conduction mechanism 11 and the monitoring mechanism 3 is started to monitor the static water flow;

[0073] When water leakage occurs, the internal water flow will flow slightly, and the corresponding arc blade 112 will be driven to rotate by the flow energy of the water flow, and the transmission rod 111, the disk 113 and the metal contact 114 will be driven to rotate by the arc blade 112. Since the metal wire 115 connects the metal contacts 114 at symmetrical positions, when the two corresponding metal contacts 114 rotate at the same time and contact the corresponding metal conductive sheet 34, the current is transmitted through the metal wire 115 to realize intermittent power connection. At this time, the controller 5 collects the intermittent power information and transmits it to the display device;

[0074] 3. By knowing that there is still an intermittent power connection when the flow control mechanism 21 is closed, the personnel can know that there is water flow in the heat sink body 1, and can promptly perform water leakage inspection and maintenance, thereby avoiding coolant leakage caused by equipment leakage, affecting the heat dissipation effect, and possibly causing electronic chips, motherboards and other key electronic components to short-circuit, damage components, cause system shutdown, and threaten the safe operation of the system.

[0075] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
