Description

Technical Field

[0001] The present invention relates to the field of cooling equipment, and in particular to a water cooling device for an MXM graphics card and a reinforced notebook. Background Art

[0002] MXM graphics cards are detachable graphics cards for computers, and are widely used in industrial and military environments that require multiple displays, high computing power, small size, and light weight. Due to the high performance of MXM graphics cards, the requirements for heat dissipation during operation are also higher.

[0003] The existing water cooling devices for MXM graphics cards mostly adopt a centrifugal design, which is very easy to generate bubbles during high-intensity heat dissipation operations. The bubbles are not discharged in time after they are generated, and they need to be operated continuously for a long time before they can be slowly discharged. Since the heat conductivity of air is much lower than that of water, the long-term existence of bubbles will have a negative impact on the heat dissipation effect. Summary of the invention

[0004] The present invention provides a water cooling device for an MXM graphics card and a reinforced notebook, which can separate and discharge bubbles, thereby reducing the negative impact on the heat dissipation effect, thereby facilitating efficient heat dissipation of the MXM graphics card and ensuring that the graphics card can always maintain a high-performance state to work.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0053] Please refer to Figure 1 and Figure 7 The water cooling device 100 for the MXM graphics card and the reinforced notebook 1000 provided in the embodiments of the present invention can solve the above problems, which will be described in detail below.

[0054] Example 1

[0055] refer to Figure 1 and Figure 2 The water cooling device 100 for the MXM graphics card includes a water pipe 110, a water pump body 120, a rotating blade 130 and a water tank 140;

[0056] Among them, a connected accommodating cavity 121 and an air guiding cavity 122 are formed in the water pump body 120, the accommodating cavity 121 is connected to the water pipe 110, the rotating blade 130 is arranged in the accommodating cavity 121, and is used to rotate under the action of external force, the water tank 140 is located on the upper side of the water pump body 120 and is connected to the accommodating cavity 121 and the air guiding cavity 122 at the same time, and a spoiler 123 is formed on the side wall of the accommodating cavity 121, and the spoiler 123 extends in the direction close to the rotating blade 130 and is separated from the rotating blade 130.

[0057] In the working state, water enters the accommodating cavity 121 through the water pipe 110 and rotates under the drive of the rotating blades 130. The spoiler 123 is used to separate the generated bubbles, so that the bubbles enter the air guide cavity 122, and enter the water tank 140 along the air guide cavity 122 and then are discharged, thereby reducing the mixing time of the bubbles and water as much as possible, thereby reducing the negative impact on the heat dissipation effect.

[0058] It should be noted that, when the water flows from the water pipe 110 into the accommodating cavity 121, the water flows with a certain flow pressure will generate bubbles due to the shear force generated by the rotation of the rotating blades 130 during the contact process with the rotating blades 130, and the existence of bubbles will reduce the heat dissipation effect of the water. The spoiler 123 is used to separate the water flow and bubbles driven by the rotating blades 130. After the water flows contact the spoiler 123, it will bypass the spoiler 123 to flow in a circumferential direction, or flow along the spoiler 123 toward the water tank 140 on the upper side. When the bubbles contact the spoiler 123, they will flow away from the rotating blades 130 to the air guide cavity 122, reducing the contact between the bubbles and the rotating blades 130. Because the bubbles are lighter, they will move along the air guide cavity 122 toward the water tank 140 on the upper side until they enter the water tank 140.

[0059] In order to facilitate the balance of the water tank 140 and the external air pressure, a waterproof breathable valve 170 can be installed at the top of the water tank 140. When the gas enters the water tank 140, it will move to the top of the water tank 140 and gather. The waterproof breathable valve 170 can achieve air pressure balance inside and outside the water tank 140, and at the same time prevent the water in the water tank 140 from overflowing.

[0060] refer to Figure 1 and Figure 2 In order to improve the diversion effect of water and bubbles and reduce the obstruction to the flow of water, the spoiler 123 can be extended from the outside to the inside along the rotation direction of the rotating blade 130. When the water contacts the spoiler 123, the spoiler 123 can guide the water and guide the water to flow along the rotation direction of the rotating blade 130, avoiding the opposite direction of the guide direction of the spoiler 123, preventing the flow of water from being obstructed, and avoiding the generation of more bubbles due to collision with the water.

[0061] At the same time, in order to reduce the moving path of the bubbles and improve the moving efficiency of the bubbles as much as possible so that the bubbles quickly enter the water tank 140 , the air guide cavity 122 can be extended along the axial direction of the rotating blade 130 .

[0062] In this embodiment, the water pump body 120 is a rectangular parallelepiped structure, there are two water pipes 110 that are respectively connected to the two sides of the water pump body 120, and there are four air guide cavities 122 that are respectively formed at the four corners of the water pump body 120; of course, in other embodiments of the present invention, the water pump body 120 can also be other shapes such as a cylinder and a triangular prism, the number of water pipes 110 can also be one, three, four, etc., the number of air guide cavities 122 can also be one, three, six, etc., and there is no limitation on the specific shape of the water pump body 120, the specific number of water pipes 110, and the specific number of air guide cavities 122.

[0063] refer to Figure 2 and Figure 3 The side wall of the accommodating cavity 121 is recessed to form an air guide groove 124 , which is connected to the air guide cavity 122 , and one end of the air guide groove 124 away from the air guide cavity 122 is connected to the water pipe 110 .

[0064] Because the water will impact the rotating blades 130 at the moment of flowing out of the water pipe 110, the rotating shear force will cause the water to generate a large number of bubbles, and by forming the air guide groove 124, the water has a larger activity space when flowing out of the inlet and outlet pipe, thereby reducing the shear impact caused by contact with the rotating blades 130, which helps to reduce the generation of bubbles. At the same time, the air guide groove 124 can play a guiding role, used to guide the water and bubbles to move in the direction close to the spoiler 123, thereby facilitating the diversion effect of the spoiler 123, and facilitating the separated bubbles to enter the air guide cavity 122.

[0065] In this embodiment, in order to facilitate the movement of water and bubbles and avoid uneven movement speed at corners, the bottom wall of the air guide groove 124 can be made arc-shaped.

[0066] refer to Figure 2 and Figure 3 In order to facilitate the disassembly, assembly and maintenance of the water pump body 120 and to install other structures in the accommodating cavity 121, the water pump body 120 may include a detachably connected upper shell 1201 and a lower shell 1202. When it is necessary to install components such as the rotating blades 130 in the accommodating cavity 121, the upper shell 1201 and the lower shell 1202 may be separated. When the upper shell 1201 or the lower shell 1202 is damaged, only the damaged shell may be replaced, thereby reducing maintenance costs.

[0067] Furthermore, the accommodating cavity 121 and the air guiding cavity 122 are both formed in the lower shell 1202, and a converging cavity 125 is formed in the upper shell 1201. The top of the converging cavity 125 is communicated with the water tank 140, and the bottom of the converging cavity 125 is connected to both the accommodating cavity 121 and the air guiding cavity 122. During operation, bubbles and water can enter the water tank 140 through the converging cavity 125 from the air guiding cavity 122 and the accommodating cavity 121, respectively.

[0068] It is worth noting that although both bubbles and water will enter the water tank 140 through the converging cavity 125, because the converging cavity 125 is formed in the upper shell 1201 and is located on the upper side of the rotating blade 130, even if the bubbles and water converge here, no additional bubbles will be generated.

[0069] Furthermore, in order to improve the convergence effect and facilitate the rapid entry of water into the water tank 140, the convergence cavity 125 may be made to have a structure that is small at the top and large at the bottom, and the axial cross-sectional size of the convergence cavity 125 gradually decreases from bottom to top.

[0070] In this embodiment, the side wall of the converging cavity 125 formed in the upper shell 1201 is a slope; of course, in other embodiments of the present invention, the side wall of the converging cavity 125 formed in the upper shell 1201 can also be a curved surface, and the direction of the curved curvature can be consistent with the direction approaching the converging cavity 125, or it can be consistent with the direction away from the converging cavity 125; that is, the rate of change of the circumferential cross-sectional size of the converging cavity 125 can gradually increase from bottom to top, or it can gradually decrease from bottom to top.

[0071] During operation, the water pump body 120 can be controlled to operate periodically, running at 50% speed for 30 seconds and then stopping for 20 seconds, thus completing 6 cycles. When the water pump body 120 stops, the bubbles will mainly return to the inside of the water tank 140 along the inclined surface on the side wall of the convergence cavity 125.

[0072] refer to Figure 2 and Figure 4 In order to improve the flow efficiency during the flow of water and bubbles, the water cooling device 100 for MXM graphics card may further include a drainage mechanism 150. The drainage mechanism 150 includes a rotating shaft 151, a first fixing plate 152, a sliding block 153 and a drainage plate 154;

[0073] The rotating shaft 151 is coaxially arranged with the rotating blade 130 and is used to rotate under the action of external force. The first fixed plate 152 is connected to the water pump body 120. The outer wall of the rotating shaft 151 is provided with a spiral groove 1511. The first fixed plate 152 is provided with a first guide hole 1521. One end of the sliding block 153 is accommodated in the spiral groove 1511. The sliding block 153 can be movably penetrated through the first guide hole 1521. The guide plate 154 is located on the upper side of the spoiler 123 and is connected to the other end of the sliding block 153. The guide plate 154 is used to rotate under the drive of the sliding block 153.

[0074] During operation, the rotating shaft 151 can rotate under the action of external force, and through the cooperation between the spiral groove 1511 and the end of the sliding block 153, the rotational motion can be converted into the sliding motion of the sliding block 153 in the axial direction of the rotating shaft 151, and the sliding of the sliding block 153 can drive the guide plate 154 to rotate to achieve the drainage effect.

[0075] Specifically, in order to make the moving speed of the sliding block 153 more accurate, the spiral slope of the spiral groove 1511 can be adaptively designed. It can be understood that when the sliding block 153 is preferably moved quickly, the spiral slope of the corresponding spiral groove 1511 can be steeper; when the sliding block 153 is preferably moved slowly, the spiral slope of the corresponding spiral groove 1511 can be gentler.

[0076] It is worth noting that, because the rotating shaft 151 can have a different rotation speed from the rotating blade 130, the water cooling device 100 for the MXM graphics card can also include a driving member 180. The driving member 180 can be disposed at the top of the water tank 140. The output shaft of the driving member 180 is coaxially connected to the rotating shaft 151, and then the driving member 180 provides power to the rotating shaft 151 to drive the rotating shaft 151 to rotate.

[0077] Specifically, the driving member 180 may be a rotary motor, a rotary cylinder or a rotary hydraulic cylinder, and its specific power shape is not limited. Of course, in other embodiments of the present invention, the rotating shaft 151 may be coaxially connected to the rotating blade 130, so that the rotating shaft 151 may be driven to rotate when the rotating blade 130 rotates.

[0078] In this embodiment, in order to reduce friction and improve the matching effect, the end of the sliding block 153 accommodated in the spiral groove 1511 can be an arc head. In addition, in order to provide a good guiding effect for the sliding of the sliding block 153, the first guide hole 1521 can be in the shape of a long strip, the extending direction of the strip (i.e., the length direction of the strip) is the axial direction of the rotating shaft 151, and the width of the long strip of the first guide hole 1521 is adapted to the width of a section of the sliding block 153 accommodated in the first guide hole 1521.

[0079] refer to Figure 2 and Figure 4 The drainage mechanism 150 also includes a second fixed plate 155; the second fixed plate 155 is connected to the water pump body 120, and the end of the drainage plate 154 away from the sliding block 153 is rotatably connected to the second fixed plate 155 through the first rotating shaft 156. The end of the drainage plate 154 close to the sliding block 153 is provided with a second guide hole 1541, and the sliding block 153 is connected to a second rotating shaft 157. The second rotating shaft 157 can be movably accommodated in the second guide hole 1541, so that the drainage plate 154 can rotate with the first rotating shaft 156 as a fulcrum.

[0080] When in use, the second fixing plate 155 is used to fix the axial position of the end of the guide plate 154 through the first rotating shaft 156, so that the end of the guide plate 154 will not easily change position without affecting the rotation of the guide plate 154. When the sliding block 153 slides up and down, it can slide in the second guide hole 1541 through the second rotating shaft 157. The second guide hole 1541 is in the shape of a long strip, and its strip extension direction (i.e., the strip length direction) is consistent with the extension direction of the guide plate 154. Its strip width is adapted to the diameter or width of the second rotating shaft 157, so that the end of the guide plate 154 close to the second rotating shaft 157 moves under the drive of the sliding block 153.

[0081] In this embodiment, a single sliding block 153 and a single second fixed plate 155 respectively correspond to six guide plates 154. The six guide plates 154 are divided into two groups and are respectively arranged on both sides of the second fixed plate 155. The three guide plates 154 on the same side are arranged at equal distances to ensure uniform flow when draining water or bubbles, thereby avoiding an increase in bubbles due to increased water flow collisions caused by uneven flow.

[0082] Of course, in other embodiments of the present invention, the number of the second fixed plates 155 can also be two, four, eight, etc. There is no limitation on the specific number of the second fixed plates 155. They can be arranged on one side of the second fixed plate 155, or symmetrically on both sides of the second fixed plate 155.

[0083] refer to Figure 2 and Figure 6 In order to improve the heat dissipation effect, other media are sometimes added to the heat dissipation liquid. However, due to the mixing of the media, it is easy for the spoiler 123 and the inner wall of the air guide cavity 122 to have adhesion after long-term use. In order to clean the adhesion and avoid its negative impact on the heat dissipation effect or the movement of the water and bubbles, the water cooling device 100 for the MXM graphics card can also include a cleaning mechanism 160.

[0084] The cleaning mechanism 160 may include a cleaning ring brush 161, which is connected to the sliding block 153 and accommodated in the air guide cavity 122. The cleaning ring brush 161 is used to move along the axial direction of the rotating blade 130 under the drive of the sliding block 153. During operation, when the sliding block 153 moves along the axial direction of the rotating shaft 151, the cleaning ring brush 161 may be driven to move synchronously, so that the cleaning ring brush 161 cleans the adhesion on the inner wall of the air guide cavity 122.

[0085] Of course, the cleaning mechanism 160 may also include a cleaning brush 162, which is connected to the sliding block 153 and is arranged close to the spoiler 123. The cleaning brush 162 is used to move along the axial direction of the rotating blade 130 under the drive of the sliding block 153. During operation, when the sliding block 153 moves along the axial direction of the rotating shaft 151, the cleaning brush 162 may be driven to move synchronously, so that the cleaning brush 162 cleans the adhesion on the spoiler 123.

[0086] It is worth noting that the cleaning ring brush 161 and the cleaning plate brush 162 can move synchronously with the sliding block 153, that is, the cleaning operation can be performed while the drainage plate 154 is draining. In addition, in order to further improve the cleaning effect, the cleaning operation can also be performed without drainage, that is, the cleaning operation can be performed exclusively without the flow of water and bubbles.

[0087] refer to Figure 5 and Figure 6 In order to improve the cleaning effect and the cleaning ability of stubborn adhesions, the cleaning mechanism 160 may further include a vibration rod 163, and the side wall of the first fixing plate 152 may be formed with at least two first arc-shaped protrusions 1522;

[0088] One end of the vibration rod 163 is connected to the sliding block 153 and cooperates with the first arc-shaped protrusion 1522 , and the other end of the vibration rod 163 is connected to the cleaning ring brush 161 and the cleaning plate brush 162 .

[0089] It can be understood that while the sliding block 153 moves, the vibration rod 163 will move along the arrangement direction of the first arc-shaped protrusions 1522, and then contact the first arc-shaped protrusions 1522 in turn, thereby achieving a vibration effect during the contact process, and the vibration rod 163 drives the cleaning ring brush 161 and the cleaning plate brush 162 to vibrate, thereby improving the cleaning ability of stubborn adhesions.

[0090] In this embodiment, the cleaning ring brush 161 is in a circular ring shape, and the cleaning plate brush 162 is in an arc plate shape, and is compatible with the arc shape of the spoiler 123; of course, in other embodiments of the present invention, the cleaning ring brush 161 can also be in other shapes such as a triangular ring, a rectangular ring, etc., and the cleaning plate brush 162 can also be in a straight plate shape, etc., and there is no limitation on the specific appearance of the two.

[0091] In order to make the excitation effect more uniform, the number of the first arc-shaped protrusions 1522 can be limited to at least three, and the at least three first arc-shaped protrusions 1522 are arranged at equal intervals.

[0092] Specifically, the vibration rod 163 includes a first extension rod 1631, a second extension rod 1632, a connecting rod 1633, an exciting rod 1634 and a spring 1635; one end of the first extension rod 1631 is connected to the sliding block 153, the other end of the first extension rod 1631 is connected to the cleaning ring brush 161 and the cleaning plate brush 162, and the end of the second extension rod 1632 close to the first fixed plate 152 is connected to the first extension rod 1631 through the connecting rod 1633 One end of the exciting rod 1634 cooperates with the first arc-shaped protrusion 1522, and the other end of the exciting rod 1634 passes through the connecting rod 1633. The spring 1635 is sleeved on the exciting rod 1634 and is supported between the connecting rod 1633 and the first arc-shaped protrusion 1522; at least two second arc-shaped protrusions 1636 are formed on the side of the second extension rod 1632 close to the first extension rod 1631, and the second arc-shaped protrusion 1636 is used to support the first extension rod 1631.

[0093] During the cleaning process, the presence of the spring 1635 and the excitation rod 1634 can reduce the impact generated when the excitation rod 1634 contacts different first arc-shaped protrusions 1522, reduce the vibration impact while having a vibration effect, and then reduce the contact damage between the excitation rod 1634 and the first arc-shaped protrusion 1522, which helps to increase the service life of both. In addition, by forming the second arc-shaped protrusion 1636 on the second extension rod 1632 and using the second arc-shaped protrusion 1636 to collide with the first extension rod 1631, it helps to transmit the vibration occurring at the end of the first extension rod 1631 close to the sliding block 153 to the cleaning ring brush 161 and the cleaning plate brush 162 located at the end of the first extension rod 1631 away from the sliding block 153.

[0096] Specifically, the reinforced notebook 1000 also includes a display 200 and a base 300. The top side of the base 300 is connected to the display 200. The water tank 140, the water pipe 110 and the water pump body 120 are all accommodated inside the base 300. The top surface of the base 300 is provided with keyboard buttons. One of the sides of the base 300 is provided with a circulating water interface 310. The circulating water interface 310 is used to communicate with the circulating water pipe and the water pipe 110 at the same time to facilitate the replacement of water. At the same time, in order to facilitate the lifting and moving of the entire reinforced notebook 1000, a portable handle can be provided on one of the sides of the base 300. The portable handle and the circulating water interface 310 are respectively provided on different sides of the base 300.

[0097] In this embodiment, the display 200 is a three-screen structure; of course, in other embodiments of the present invention, the display 200 can also be a single-screen, dual-screen or quad-screen structure, etc., and there is no limitation on the specific number of screens.

[0098] In summary, the water cooling device 100 for MXM graphics cards and the reinforced notebook 1000 provided by the embodiments of the present invention have at least the following advantages:

[0099] (1) The generated bubbles can be separated by setting a spoiler 123, so that the bubbles enter the air guide cavity 122, and then enter the water tank 140 along the air guide cavity 122 and then are discharged, thereby reducing the mixing time of the bubbles and the water as much as possible, thereby reducing the negative impact on the heat dissipation effect.

[0100] (2) By limiting the extension direction of the spoiler 123 and the air guide cavity 122, the separation effect of water and bubbles can be improved, and the moving speed of bubbles can be increased, so that bubbles can quickly enter the water tank 140 through the air guide channel.

[0101] (3) It is provided with a drainage mechanism 150, and the rotational motion of the rotating shaft 151 is converted into the axial movement of the sliding block 153 and then into the flipping motion of the drainage plate 154, so as to achieve the drainage effect on the water and facilitate the water to quickly enter the water tank 140.

[0102] (4) By setting a cleaning mechanism 160, the cleaning ring brush 161, the cleaning plate brush 162 and the vibration rod 163 can move with the sliding block 153, thereby realizing the cleaning operation of the adhesion on the air guide cavity 122 and the spoiler 123, thereby avoiding the negative impact of the residual adhesion on the heat dissipation effect.

[0103] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
