DETAILED DESCRIPTION

[0029] like Figures 1 to 9 As shown, the present invention is a high-efficiency liquid cooling heat dissipation system, including a vortex cooling plate 1, a slide 2, a slider 3, a longitudinal displacement drive device 4, a base plate 5 and a transverse displacement drive device 6. The vortex cooling plate 1 is vortex-shaped and gradually transports cooling liquid from the center to the outside. The vortex cooling plate 1 is arranged on the slide 2, and the slide 2 and the slider 3 slide together in the longitudinal direction. The longitudinal displacement drive device 4 is arranged on the slider 3, and the output end of the longitudinal displacement drive device 4 is connected to the slide 2. The transverse displacement drive device 6 is arranged on the base plate 5, and the output end of the transverse displacement drive device 6 is connected to the slider 3. The transverse direction mentioned here refers to the length direction of the base plate 5, and the corresponding vertical direction is the longitudinal direction.

[0030] In the embodiment of the present invention, the longitudinal displacement driving device 4 includes a first motor, a first guide rod, and a first screw connected to the output end of the first motor, wherein the first guide rod is fixed on the slider 3, the slider 2 is slidably matched with the first guide rod, and the first screw is threadedly connected to the slider 2. After the first motor rotates, the slider 2 can be driven to slide longitudinally. Similarly, the transverse displacement driving device 6 of the present invention includes a second motor, a second guide rod, and a second screw connected to the output end of the second motor, wherein the second guide rod is fixed on the floor, the slider 3 is slidably matched with the second guide rod, and the second screw is threadedly connected to the slider 3. After the second motor rotates, the slider 3 can be driven to slide transversely. There is a gap between the slider 3 and the floor to avoid contact with the infrared thermometer 7.

[0031] In the present invention, a plurality of infrared thermometers 7 are arranged in an array on the bottom plate 5. All kinds of controller components of the present invention can be arranged on the bottom plate 5. The infrared thermometers 7 are installed on the bottom plate 5 in a rectangular array. The light used for measuring temperature is along the normal direction of the bottom plate 5. The infrared thermometers 7 periodically measure the temperature of the corresponding position of the bottom plane of the upper device to be cooled. Each infrared thermometer 7 corresponds to a temperature measurement area of ​​the bottom plane of the device to be cooled and measures the temperature thereof. The comparison circuit is used for comparison to determine the position of the infrared thermometer 7 with the highest temperature. The controller converts the position into coordinates and controls the longitudinal displacement drive device 4 and the lateral displacement drive device 6 to move the position on the plane so as to move the vortex cooling plate 1 directly below the position, thereby realizing the targeted cooling action, and thus effectively improving the heat dissipation efficiency.

[0032] In this embodiment, the vortex cooling disk 1 includes a cooling coil 8, which is spirally arranged from the inside to the outside. One end of the cooling coil 8 is connected to a first water pump 9, which is arranged at the central end of the cooling coil 8. The water supply end of the first water pump 9 is connected to a liquid capsule 10, which is arranged on the inner side of the cooling coil 8. By continuously supplying water to the liquid capsule 10, the liquid capsule 10 can expand from one end of the cooling coil 8 to the other end. The specific setting method is that the first water pump 9 is connected to a joint, and a water inlet and a water outlet are provided on the joint at the same time. A valve is provided at the water outlet. When the valve is closed, the joint can only take in water to supply water to the liquid capsule 10 and expand it. When the required expansion area is reached, the valve is opened so that the water inlet and the water outlet of the joint can enter and exit normally, so that the normal replacement and heat exchange of the coolant in the liquid capsule 10 can be realized, and the liquid capsule 10 no longer has obvious expansion force.

[0033] In this embodiment, a ball 11 is provided in a rolling manner inside the cooling coil 8. The ball 11 can roll under the expansion of the liquid capsule 10. An electromagnetic brake is installed inside the ball 11. The output end of the electromagnetic brake is connected to a rotating shaft 12. An open groove 13 is provided on the inner side of the cooling coil 8 along its axial direction. The rotating shaft 12 and the open groove 13 are slidably matched. When the ball 11 rolls, the rotating shaft 12 can be driven to slide along the open groove 13. After the rotating shaft 12 extends out of the open groove 13, a gear 14 is coaxially connected. The gear 14 is meshed with a rack 15, and the rack 15 is fixed on the outer side of the cooling coil 8. In the embodiment of the present invention, the shape arrangement of the rack 15 is set as needed to adapt to the shape of the vortex structure so that it can mesh with the gear 14 as perfectly as possible at all times. A suitable cooling area is determined by the temperature measurement of the infrared thermometer 7, and the cooling area corresponds to the expansion degree of the liquid capsule 10, that is, the expansion length of the liquid capsule 10 is determined, and the number of turns of the rotating shaft 12 can be determined. When the rotating shaft 12 drives the gear 14 to reach the set number of turns, the electromagnetic brake drives the rotating shaft 12 to stop rotating. At this time, the gear 14 no longer moves under the limiting action of the rack 15, which can ensure the positioning effect of the gear 14 and the sphere 11 connected to it, so as to prevent the liquid capsule 10 from continuing to expand and achieve the purpose of limiting. By limiting with the electromagnetic brake, the expansion area of ​​the liquid capsule 10 can be set according to demand, and the liquid capsule 10 can control the expansion degree according to the setting of the first water pump 9. The pressure sensor is close to the outer end of the liquid capsule 10 for measuring the pressure on the surface of the liquid capsule 10. Therefore, the expansion degree can also be controlled according to the electromagnetic brake under the measurement of the pressure sensor, which is convenient for control.

[0034] In this embodiment, a through hole 16 is opened at the top of the cooling coil 8, and a guide column 17 is slidably arranged in the through hole 16. The upper and lower ends of the guide column 17 are fixedly connected to the contact top plate 18 and the arc-shaped heat dissipation plate 19 respectively. The arc-shaped heat dissipation plate 19 is located on the inner side of the cooling coil 8. After the liquid capsule 10 arrives, the inner wall of the arc-shaped heat dissipation plate 19 can abut the liquid capsule 10, so that the temperature of the upper equipment can be timely transmitted to the liquid capsule 10 through the arc-shaped heat dissipation plate 19 and the contact top plate 18, thereby playing a more direct and efficient heat dissipation effect.

[0035] In this embodiment, a spring 20 is also connected between the arc-shaped heat sink 19 and the inner wall of the cooling coil 8. One end of the spring 20 is fixedly connected to the back side of the arc-shaped heat sink 19, and the other end is fixedly connected to the inner side of the cooling coil 8. By providing the spring 20, an inward pre-tightening force can be provided for the contact top plate 18, thereby avoiding interference between the contact top plate 18 and the equipment in the initial stage of movement. In the present invention, one arc-shaped heat sink 19 corresponds to two groups of springs 20. The pre-tightening force of the spring 20 close to the center end of the cooling coil 8 is smaller, which can facilitate the expansion of the liquid bag 10.

[0036] In this embodiment, a linear motor 21 is fixed on the slide 2, and the output end of the linear motor 21 is connected to the first water pump 9, and can also be connected to the cooling coil 8. Through the output of the linear motor 21, the cooling coil 8 can be driven to move up and down as a whole to better contact with the part of the equipment that needs heat dissipation, thereby facilitating heat dissipation.

[0037] In this embodiment, an auxiliary cooling pipe 22 is fixed to the outside of the cooling coil 8, and the auxiliary cooling pipe 22 is connected to the second water pump 23. A proximity switch is provided in the middle of the cooling coil 8, and the second water pump 23 is activated when the liquid capsule 10 reaches the proximity switch. When the temperature is really high, the cooling speed of the cooling coil 8 can no longer meet the requirements, so the second water pump 23 can be activated, and the auxiliary cooling pipe 22 can assist in heat dissipation. At the same time, the auxiliary cooling pipe 22 can also exchange heat with the cooling coil 8, thereby improving the heat dissipation efficiency of the device. An elastic telescopic support seat 24 is provided on the slide 2, and the elastic telescopic support seat 24 is made of rubber material. The elastic telescopic support seat 24 is used to limit the auxiliary cooling pipe 22 and the cooling coil 8 at the same time, which can ensure the operating stability of the device.

[0038] In this embodiment, a plurality of transverse tubes 25 are evenly spaced and fixed along the longitudinal direction of the slider 3, and the two ends of the transverse tube 25 are connected with an air inlet pipe 26 and an air outlet pipe 27, and a plurality of air delivery holes 28 are arranged at intervals on the transverse tube 25, and the air delivery holes 28 are connected with a nozzle 29, and the nozzle 29 extends vertically upward. The bottom of the device can be air-cooled and dissipated through the nozzle 29, which can enhance the heat dissipation effect of the device.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
