Description

Technical Field

[0001] The invention relates to the technical field of mainboard cooling, and in particular to a liquid cooling circulation device for a computer mainboard. Background Art

[0002] Computers generate heat during operation, and high heat can cause problems such as unstable system operation, shortened integrated circuit life, and device damage, which can seriously affect the normal operation of the computer. At present, the most common way to dissipate heat generated by computer motherboards is air cooling, that is, cooling the motherboard by installing a fan on the motherboard. However, the single air cooling effect is poor and can no longer meet the heat dissipation requirements of the computer. Therefore, liquid cooling is proposed. Liquid cooling occupies less space on the motherboard, and the heat dissipation effect is much better than that of air cooling. However, the installation and maintenance costs of liquid cooling are high. First, a cooling source is required to continuously output energy to the coolant to ensure that the temperature of the coolant is always kept at a low temperature to complete heat exchange with the heat sink on the motherboard. In addition, a power device is required to drive the coolant to circulate continuously. Both of these require corresponding energy input to achieve normal operation. Therefore, liquid cooling is restricted in its wide application both in terms of energy saving and preparation and maintenance costs. Based on this, the present invention is proposed.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0036] like Figure 1-11 As shown, this embodiment proposes a computer motherboard liquid cooling circulation device, which is suitable for the heat sink on the computer motherboard, and specifically includes a base plate 1 with a rectangular structure. The bottom of the base plate 1 is integrally formed with a limit frame 8 that is adapted to the size of the heat sink, and the top is fixed with an outer shell 2. The interior of the outer shell 2 is respectively provided with a refrigeration box 21 and a coolant circulation box 24. A notch with a rectangular structure is also formed through the middle of the base plate 1, and the notch is consistent with the bottom of the outer shell 2 and the inner cross-section of the limit frame 8. When the entire device is installed, the limit frame 8 is inserted into the heat sink on the motherboard so that the heat sink is clamped by the limit frame 8 on all sides and the top is tightly fitted with the outer shell 2, and then bolts are implanted through the bolt holes at the edge of the base plate 1 to complete the fixation.

[0037] A refrigeration box 21 and a coolant circulation box 24 are arranged inside the outer shell 2, wherein a semiconductor refrigeration tube 23 is installed inside the refrigeration box 21 for cooling the refrigerant, and a serpentine liquid flow channel is formed inside the coolant circulation box 24. The refrigeration box 21 and the coolant circulation box 24 are connected by two connecting pipes 22. The cooled coolant in the refrigeration box 21 enters the coolant circulation box 24, and the coolant circulates in the coolant circulation box 24 along the serpentine liquid flow channel, so that the coolant and the heat sink form heat exchange, thereby cooling the heat sink.

[0038] After the coolant and the heat sink complete the heat exchange, its temperature gradually rises. In order to continuously cool down the heat sink, the traditional method is to install a pressure pump inside the refrigeration box 21, and continuously pump the coolant whose internal temperature is reduced into the coolant circulation box 24 through the pressure pump. After the coolant inside the coolant circulation box 24 completes the heat exchange, it flows back into the refrigeration box 21, and this cycle is repeated continuously. Using current technical means, two electrical devices are required. The first is a pressure pump to drive the flow of coolant, and the second is a power supply for the semiconductor refrigeration tube 23. Both require the help of the power module on the mainboard to ensure normal operation.

[0039] In order to realize energy-saving operation of the whole device, the present invention promotes the circulation of coolant in the refrigeration box 21 and the coolant circulation box 24 by mechanical disturbance. Specifically, a guide plate 25 is connected to the first turning point of the serpentine liquid flow channel inside the coolant circulation box 24 (a serpentine fluid flow channel is formed by a plurality of partitions arranged laterally inside the coolant circulation box 24), the guide plate 25 is arranged perpendicular to the partition, and a coolant disturbance plate 20 is slidably installed in the area between the guide plate 25 and the inner wall of the coolant circulation box 24. The piston rod 19 connected to one end of the coolant disturbance plate 20 extends to the outside of the outer shell 2, and the piston rod 19 is reciprocated along its axial direction to push the coolant disturbance plate 20 to move in the area between the guide plate 25 and the inner wall of the coolant circulation box 24. 20 includes a fixed seat 202 fixedly connected to the piston rod 19, and rotating plates 201 of the same specifications are hinged on both sides of the fixed seat 202. The two rotating plates 201 are connected by a flexible connecting strip 203 on the side away from the piston rod 19. When the piston rod 19 is driven to move toward the inside of the coolant circulation box 24, the two rotating plates 201 are affected by the coolant and rotate in the direction away from each other. Finally, the two are fully unfolded and always maintain this state under the action of the flexible connecting strip 203. The two unfolded rotating plates 201 form a disturbance to the coolant to make it flow. When the piston rod 19 moves toward the outside of the coolant circulation box 24, the two rotating plates 201 are affected by the liquid resistance and rotate toward each other, which will not disturb the coolant. The reciprocating movement of the piston rod 19 causes the coolant to circulate in a single direction.

[0040] For the reciprocating movement of the piston rod 19, the present invention distributes transverse moving plates 5 on both sides of the outer shell 2, and the ends of the two transverse moving plates 5 are connected by a guide rod 11, and the two guide rods 11 maintain a sliding connection with the outer shell 2. The outer end of the piston rod 19 extends to the outside of the outer shell 2 and is fixedly connected to the corresponding transverse moving plate 5. By driving the two transverse moving plates 5 to slide reciprocatingly relative to the outer shell 2, the piston rod 19 is driven to reciprocate.

[0041] The reason why the present invention sets two transverse moving plates 5 to slide synchronously is that the mechanical energy of the movement of the two transverse moving plates 5 is converted into electrical energy to provide power for the operation of the semiconductor refrigeration tube 23. The present invention first sets a support plate 3 on the top of the outer shell 2, and a shield 4 is provided on the support plate 3. A generator 12 is installed in the shield 4. The generator 12 is electrically connected to the semiconductor refrigeration tube 23 through a wire 7. A small bevel gear 13 is fixedly sleeved on the output shaft of the generator 12. A large bevel gear 14 meshing with the small bevel gear 13 is also rotatably installed on the top of the support plate 3, and a spur gear 15 concentrically arranged with the large bevel gear 14 is rotatably installed on the upper end surface of the outer shell 2. The two are fixed by a connecting shaft to rotate synchronously. A sliding frame 6 is set between the two transverse moving plates 5. Meshing teeth 16 that alternately mesh with the spur gear 15 are distributed on both sides of the sliding frame 6. The upper end surface of the outer shell 2 is located on both sides of the spur gear 15 and is parallel to the closed guide rails 17. The two closed guide rails 17 are in a parallelogram structure. The sliding frame 6 It includes a first frame rod 62 and a second frame rod 63 arranged in parallel. The first frame rod 62 and the second frame rod 63 have meshing teeth 16 evenly distributed along the length direction on one side facing each other and meshing with the spur gear 15. The bottoms of the first frame rod 62 and the second frame rod 63 are fixedly connected with guide blocks 18 adapted to the closed guide rail 17. The two guide blocks 18 slide in the corresponding closed guide rail 17. Both ends of the first frame rod 62 and the second frame rod 63 are fixedly connected by connecting short rods 64, and the ends of the first frame rod 62 and the second frame rod 63 are fixedly connected with a slide seat 61. The slide seat 61 is located on the top of the transverse moving plate 5 and is slidably connected thereto (a T-shaped limit rail is formed on the top of the transverse moving plate 5 along its length direction, and the slide seat 61 is sleeved on the T-shaped limit rail to prevent the slide frame 6 from slipping off the transverse moving plate 5).In the initial state, the meshing teeth 16 distributed on one of the first frame rod 62 or the second frame rod 63 mesh with the spur gear 15. For ease of understanding, in the initial state, the meshing teeth 16 distributed on the first frame rod 62 mesh with the spur gear 15. When the two transverse moving plates 5 move to move the piston rod 19 toward the inside of the coolant circulation box 24, the meshing teeth 16 on the first frame rod 62 mesh with the spur gear 15 and drive the spur gear 15 to keep rotating counterclockwise. When the meshing teeth 16 on the first frame rod 62 are all meshed with the spur gear 15, the guide block 18 at this time just slides to the inclined portion of the closed guide rail 17. As the transverse moving plate 5 moves further, the guide block 18 slides on the inclined portion of the closed guide rail 17, thereby driving the first rod 62 to move in the direction away from the spur gear 15, while the second rod 63 gradually approaches the spur gear 15. When the guide block 18 slides to the end of the inclined portion of the closed guide rail 17, the transverse moving plate 5 moves to the extreme state at this time, and then the two transverse moving plates 5 reciprocate. During the reciprocating process, the meshing teeth 16 on the first rod 62 do not mesh with the spur gear 15, while the meshing teeth 16 on the second rod 63 mesh with the spur gear 15, thereby continuing to drive the spur gear 15 to continue to rotate counterclockwise.

[0042] During the synchronous reciprocating motion of the two transverse moving plates 5, the spur gear 15 always rotates in the same direction, and the spur gear 15 drives the large bevel gear 14 to rotate synchronously therewith. The diameter ratio of the small bevel gear 13 to the large bevel gear 14 is 1:2. After speed change, it can output twice the speed to the generator 12, so that the generator 12 can work to generate electricity to power the semiconductor refrigeration tube 23, thereby achieving energy saving effect.

[0043] Furthermore, a rotating disk 10 is rotatably mounted inside the bottom plate 1 corresponding to the middle of each transverse moving plate 5, and a limiting column 27 is fixed in the vertical direction at the eccentric position of the upper end surface of each rotating disk 10, and a sliding groove 26 is provided at the bottom of the transverse moving plate 5 corresponding to the position of the limiting column 27. When the rotating disk 10 rotates, the limiting column 27 slides inside the sliding groove 26, thereby pushing the two transverse moving plates 5 to perform reciprocating linear motion. In the present invention, the only power device of the entire device is to drive the rotating disk 10 to rotate, and a power is set to drive one of the rotating disks 10, which can minimize the input of energy. The power device used to drive the rotating disk 10 to rotate is not specifically limited in the present invention, so it is not specifically illustrated in the drawings. The power device can be a motor fixed inside the bottom plate 1, and a first gear is sleeved on the outside of the rotating disk 10, and a second gear meshing with the first gear is rotatably mounted inside the bottom plate 1, and the second gear is driven to rotate by the motor, and the rotation of the rotating disk 10 can be driven by the meshing of the first gear and the second gear.

[0044] In addition, the present invention can also realize liquid cooling and air cooling of the heat sink at the same time, thereby improving the heat dissipation efficiency. To this end, a cross-moving frame 28 is fixedly connected to the bottom of each rotating disk 10 through a shaft rod, and a groove is formed at the bottom of the bottom plate 1 corresponding to the position of each cross-moving frame 28. The cross-moving frame 28 is located in the groove. The limit frame 8 is integrally connected to the middle of both sides of the cross-moving frame 28, and each connecting tube 9 is hollow inside. The limit frame 8 also has an air-cooling channel 29 connected to the connecting tube 9, and both ends of the air-cooling channel 29 extend to communicate with the outside. The area in the limit frame 8 where the air-cooling channel 29 is opened is open toward each other. The extended end of each connecting tube 9 is a closed structure, and a piston block 30 is slidably installed inside it. The top of the two piston blocks 30 is fixedly connected to a force rod 34 at one end away from each other. The top of the connecting tube 9 is provided with a limit groove 33 for the force rod 34 to slide corresponding to the sliding direction of each force rod 34. A guide column 31 is also fixed to the extended end inside the connecting pipe 9, and the piston block 30 is slidably connected to the corresponding guide column 31. A spring 32 is also sleeved on the outside of each guide column 31. One end of the spring 32 is fixedly connected to the inner wall of the connecting pipe 9, and the other end is connected to the piston block 30. When the rotating disk 10 rotates, the cross-moving frame 28 rotates synchronously with it. During the rotation of the cross-moving frame 28, it acts on the force-bearing rod 34, thereby driving the piston block 30 to slide inside the connecting pipe 9. During each rotation cycle of the rotating disk 10, the cross-moving frame 28 drives the corresponding piston block 30 to perform four reciprocating motions. Since a one-way valve is installed at both ends of each air-cooling flow channel 29, and the opening directions of the two one-way valves are opposite, during the process of the piston block 30 performing a cycle of reciprocating sliding inside the connecting pipe 9, the external air enters the connecting pipe 9 from one of the one-way valves, and is then discharged from the other one-way valve. Such a high-frequency reciprocating cycle can achieve air cooling of the heat sink.
