Description

Technical Field

[0001] The present invention relates to the technical field of server chassis, and particularly relates to a self-cooling type chassis with adjustable size. Background Art

[0002] Currently in the market, for different numbers of CPU cores, the required chassis sizes are different. The more CPU cores there are, the larger the motherboard size needed, and thus the larger the chassis. For example, for 2 CPU cores, a 62 cm or 75 cm chassis is required, and for 4 CPU cores, an 85 cm or 96 cm chassis is used. During the production process, according to the different numbers of CPU cores of each manufacturer's products, the chassis is designed and adapted according to requirements. When producing products of multiple sizes, there are many chassis specification sizes, increasing the mold opening requirements, resulting in too high overall production costs. Moreover, when the existing chassis is in use, it is cooled by air-cooling, with poor heat dissipation effect, resulting in poor overall heat dissipation efficiency, thus affecting the processing performance of the equipment inside the chassis.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Referring to Figures 1 - 9 , the present invention proposes a self-cooling and size-adjustable chassis, which includes five boxes 1 arranged in sequence from top to bottom. Except for the boxes 1 at the uppermost and lowermost positions, the remaining boxes 1 each include a bottom plate 2 and a cover plate 3 that are arranged oppositely and abut against each other and are connected by bolts. The bottom plate 2 has a U-shaped structure and its U-shaped opening faces the cover plate 3. The bottom plate 2 is used for installing and fixing the main board.

[0030] The bottom plate 2, the cover plate 3, and the top end of the bottommost box body 1 are all provided with card slots 5, and the bottom plate 2, the cover plate 3, and the bottom end of the uppermost box body 1 are all provided with clamping plates 4 adapted to the card slots 5. The clamping plate 4 of the upper bottom plate 2 is clamped in the card slot 5 of the lower bottom plate 2, and the clamping plate 4 is bolted to the lower bottom plate 2. The clamping plate 4 of the upper cover plate 3 is clamped in the card slot 5 of the lower cover plate 3, and the clamping plate 4 is bolted to the lower cover plate 3. The clamping plate 4 of the uppermost box body 1 is clamped in the card slots 5 of the uppermost bottom plate 2 and cover plate 3, and the clamping plates 4 of the bottommost bottom plate 2 and cover plate 3 are clamped in the card slot 5 of the bottommost box body 1.

[0031] In this embodiment, the box body 1 in the middle is divided into a bottom plate 2 and a cover plate 3. According to the size of the main board to be installed, different sizes of the bottom plate 2 and cover plate 3, or different combinations of the number of the bottom plate 2 and cover plate 3 can be selected to realize the adjustment of the size of the entire chassis, which can adapt to various different models of chassis, has strong adaptability, and can be designed / molded once for multiple uses during design and production. By using the form of clamping and engaging the card slot 5 and the clamping plate 4, the connection and fixation of adjacent bottom plates 2, adjacent cover plates 3, the bottom plate and the cover plate with the uppermost box body 1, and the bottom plate 2 and the cover plate 3 with the bottommost box body 1 are realized, making the connection between the box bodies 1 more stable and ensuring the stability of the entire chassis.

[0032] In this embodiment, referring to Figures 3 - 7 , a storage box 9 is provided in the bottommost cover plate 3, and a delivery pump 43 is installed in the storage box. A partition plate 44 for separating the circulating coolant is provided in the storage box 9, and a communicating return hole 45 is provided on the partition plate 44. Heat dissipation grooves 6 are provided in the remaining bottom plates 2 and cover plates 3, and one heat dissipation groove 6 is provided on the inner walls of the uppermost and bottommost box bodies 1. The heat dissipation groove 6 is in an S-shaped structure. Drain holes 7 and water inlet holes 8 are provided in the heat dissipation groove 6 and the storage box 9. A connecting pipe 12 is connected to the water inlet hole 8. The connecting pipe 12 of the upper cover plate 3 is inserted into the drain hole 7 of the lower cover plate 3, and the connecting pipe 12 of the bottommost cover plate 3 is inserted into the drain hole 7 of the bottommost box body 1. The connecting pipe 12 of the uppermost box body 1 is inserted into the drain hole 7 of the uppermost cover plate 3, and the connecting pipe 12 of the uppermost bottom plate 2 is inserted into the drain hole 7 of the uppermost box body 1. The connecting pipe 12 of the lower bottom plate 2 is inserted into the drain hole 7 of the upper bottom plate 2, and the connecting pipe 12 of the bottommost box body 1 is inserted into the drain hole 7 of the bottommost bottom plate 2. By providing heat dissipation grooves 6 in the box body 1, the bottom plate 2, and the cover plate 3, and setting coolant in the heat dissipation grooves 6, the heat generated by the chassis is adsorbed in time by the coolant, thus effectively realizing the cooling of the chassis and preventing the temperature inside the chassis from being too high.

[0033] Furthermore, referring to Figures 3 - 7 , a first adjusting ring 14 is fixedly installed in each drain hole 7. A first adjusting plate 15 that can seal the first adjusting ring 14 is arranged on the side of the first adjusting ring 14 away from the connecting pipe 12 in the drain hole 7. First adjusting grooves 16 are formed on both sides of the first adjusting plate 15 in the drain hole 7. A first connecting block 17 is slidably connected in the first adjusting groove 16, and a first spring 18 connected to the first connecting block 17 is arranged in the first adjusting groove 16. Both sides of the first adjusting plate 15 are respectively connected to the two first connecting blocks 17. When the first spring 18 is in a natural state, the first adjusting plate 15 is located in the first adjusting ring 14 to seal the first adjusting ring 14. A second adjusting ring 19 is fixedly installed in the water inlet hole 8. A second adjusting plate 20 that can seal the second adjusting ring 19 is arranged on the side of the second adjusting ring 19 away from the connecting pipe 12 in the water inlet hole 8. Second adjusting grooves 21 are formed on both sides of the second adjusting plate 20 in the water inlet hole 8. A second connecting block 22 is slidably connected in the second adjusting groove 21, and a second spring 23 connected to the second connecting block 22 is arranged in the second adjusting groove 21. Both sides of the second adjusting plate 20 are respectively connected to the two second connecting blocks 22. When the second spring 23 is in a natural state, the second adjusting plate 20 is located in the second adjusting ring 19 to seal the second adjusting ring 19. An adjusting member for driving the first adjusting plate 15 and the second adjusting plate 20 to move simultaneously to open the first adjusting ring 14 and the second adjusting ring 19 at the same time is installed in the water inlet hole 8. Specifically: the adjusting member includes a positioning ring 24 and a positioning rod 25. The positioning ring 24 is arranged on the side of the second adjusting plate 20 close to the connecting pipe 12, and the positioning ring 24 is fixed to the inner wall of the water inlet hole 8 through a bracket. The positioning rod 25 is coaxial with the connecting pipe 12 and passes through the connecting pipe 12 and extends into the drain hole 7. The positioning rod 25 penetrates through the positioning ring 24 and is slidably connected with the positioning ring 24. Limit blocks 26 for preventing the positioning rod 25 from falling off and separating are fixed on both sides of the positioning rod 25 located on both sides of the positioning ring 24. The length of the positioning rod 25 is greater than the distance between the first adjusting ring 14 and the second adjusting ring 19.

[0034] The designs of the first adjusting plate 15, the second adjusting plate 20 and the adjusting member can achieve the selective sealing of the drain hole 7 and the water inlet hole 8. Before the overall assembly or after disassembly, the first adjusting plate 15 and the second adjusting plate 20 respectively seal the drain hole 7 and the water inlet hole 8. When in use after assembly, due to the action of the adjusting member, the first adjusting plate 15 and the second adjusting plate 20 respectively release the sealing of the drain hole 7 and the water inlet hole 8, so that the coolant forms a closed loop inside the chassis, which is better for installation. While ensuring the heat dissipation of the coolant, it is also convenient for the overall installation or disassembly. At the same time, the designs of the first spring 18, the first connecting block 17, the second spring 23 and the second connecting block 22 can achieve the automatic sealing of the drain hole 7 and the water inlet hole 8 by the first adjusting plate 15 and the second adjusting plate 20 respectively before the overall installation or after disassembly of the chassis. The coolant inside the heat dissipation groove 6 will not flow out, ensuring the overall sealing performance and preventing the loss of coolant. The designs of the connecting pipe 12, the positioning ring 24 and the positioning rod 25 are such that when the cover plate 3 or the bottom plate 2 is about to be connected, the connecting pipe 12 can first be inserted into the drain hole 7, so that the drain hole 7 and the water inlet hole 8 are in a communicating state. When the cover plate 3 or the bottom plate 2 continues to be connected, when the two ends of the positioning rod 25 respectively contact the first adjusting plate 15 and the second adjusting plate 20, and the connecting pipe 12 is still being inserted, the positioning rod 25 will push the first adjusting plate 15 and the second adjusting plate 20 to open the first adjusting ring 14 and the second adjusting ring 19, so that the corresponding drain hole 7 and the water inlet hole 8 are connected, and thus the two heat dissipation grooves 6 are connected. During the whole process, the coolant will not leak. During the disassembly process, only the coolant between the first adjusting plate 15 and the second adjusting plate 20 will leak. After disassembly, the first adjusting plate 15 and the second adjusting plate 20 can respectively automatically seal the first adjusting ring 14 and the second adjusting ring 19 under the action of the first spring 18 and the second spring 23 to prevent the loss of coolant.

[0035] Further, referring to Figures 8 - 9, on both the inner and outer sides of the bottom plate 2 and the cover plate 3 of the box body in the middle, a plurality of flow dividing grooves 27 communicating with the inner heat dissipation grooves 6 thereof and a plurality of spraying mechanisms are provided, and the plurality of spraying mechanisms are respectively in one-to-one correspondence and communication with the plurality of flow dividing grooves 27. The spraying mechanism includes a spraying disc 28 and a connecting disc 29. A connecting groove 30 is provided on the connecting disc 29. A first pipe 31 is connected to the bottom of the connecting groove 30, and a second pipe 32 is slidably connected in the first pipe 31. A communication hole 33 coaxial with and communicating with the first pipe 31 is opened at the bottom of the connecting groove 30. An elastic band 34 connected to the second pipe 32 and enabling the second pipe 32 to move into the first pipe 31 is connected in the communication hole 33. A flow dividing pipe 35 coaxial with and communicating with the communication hole 33 is installed on the side of the connecting disc 29 away from the connecting groove 30. The flow dividing pipe 35 is in threaded fit connection with the flow dividing groove 27; the spraying disc 28 is slidably installed in the connecting groove 30. A spraying groove 36 is opened in the spraying disc 28, and the end of the second pipe 32 away from the first pipe 31 is rotatably and fittingly installed in the spraying groove 36. A plurality of spraying holes 37 communicating with the spraying groove 36 are opened on the spraying disc 28. The design of the flow dividing groove 27 can, when the temperature inside the chassis is too high, enable the coolant to enter the spraying mechanism through the flow dividing groove 27, and use the spraying mechanism to spray the coolant to a fixed point on the outer wall of the chassis or a position that has no influence on the internal equipment of the chassis. By using the principle of heat absorption by evaporation, the overall heat dissipation effect is further improved, making the overall heat dissipation faster and ensuring the performance of the chassis.

[0036] The spraying direction of the spraying holes 37 is inclined downward. The reaction force after the spraying holes 37 spray can drive the spraying disc 28 to rotate, realizing rotary spraying. The design of the first pipe 31 and the second pipe 32 realizes the connection function and also realizes the telescopic adjustment of the telescopic pipe; the second pipe is rotatably and fittingly connected with the spraying disc, which can realize the rotation between the spraying disc 28 and the second pipe 32, so that the rotation of the spraying disc 28 will not drive the second pipe 32 to rotate. Coupled with the design of the elastic band 34, when the water pressure returns to normal and the pressure decreases, the coolant cannot enter the flow dividing groove 27. Thus, the elastic band 34 is used to drive the telescopic pipe to automatically contract, making the spraying disc 28 return to its initial position, effectively preventing the spraying disc 28 from occupying space.

[0037] Furthermore, referring to Figures 8 - 9, a third adjusting ring 38 is fixedly installed in the flow dividing groove 27. A third adjusting plate 39 for sealing the third adjusting ring 38 is arranged on one side of the third adjusting ring 38 close to the flow dividing pipe 35 in the flow dividing groove 27. Third adjusting grooves 40 are formed in the inner wall of the flow dividing groove 27 at both sides of the third adjusting plate 39. A third connecting block 41 and a third spring 42 connected to the third connecting block 41 are slidably connected in the third adjusting groove 40. Both sides of the third adjusting plate 39 are respectively connected to the two third connecting blocks 41. When the third spring 42 is in the natural state, the third adjusting plate 39 is located in the third adjusting ring 38 to seal the third adjusting ring 38.

[0038] The design of the third adjusting plate 39 and the third spring 42 enables the flow rate during the normal transportation of the delivery pump 43 to exactly pass through the return hole 45. And during normal transportation, the pressure in the heat dissipation groove 6 cannot push the third spring 42 to open the third adjusting ring 38. When heat dissipation is required, the delivery pump 43 is started to increase the delivery power of the delivery pump 43. In this way, the flow rate delivered by the delivery pump 43 is greater than the flow rate returned through the return hole 45, resulting in the accumulation of the coolant in the heat dissipation groove 6 and an increase in the internal pressure. Such an increase in pressure can overcome the elasticity of the third spring 42 and extrude the third adjusting plate 39 outwards, so that the coolant can flow out of the flow dividing groove 27 and enter the spraying mechanism, achieving the effect of spraying and cooling. With such a design, only by adjusting the delivery power of the delivery pump 43, the automatic spraying of the spraying mechanism can be realized. And under normal cooling conditions, the coolant cannot be sprayed out from the spraying mechanism, ensuring the overall stability. Only when the temperature is too high and the delivery power of the delivery pump 43 is increased, the automatic spraying of the spraying mechanism is realized. It not only achieves the effect of spraying and cooling, but also reduces the addition of extra equipment and saves more costs.

[0039] In the embodiment, the flow dividing groove 27 and the spraying mechanism can also be arranged on the outer side of the upper or lower box body 1, so that the upper or lower box body 1 can also be sprayed and cooled, thereby improving the overall heat dissipation effect.

[0040] In this application, a solenoid valve can also be arranged in the return hole 45. When spraying is required, the solenoid valve is closed to stop the return of the coolant, so that the coolant can better enter the flow dividing groove 27 without changing the delivery power of the delivery pump 43.

[0041] When this embodiment is in use:

[0042] In this application, when 2 CPUs are required, only 3 boxes are needed. The box in the middle is composed of a bottom plate and a cover plate. After combination, through the cooperation of the clamping plate and the clamping groove, the middle box is snap-connected to the upper and lower boxes 1, and the clamping plate is connected and fixed to the two boxes by bolts. The connection between the cover plate 3 and the bottom plate 2 is also connected and fixed by bolts;

[0043] When 4 CPUs or more CPUs are required, the number of intermediate boxes (composed of a cover plate 3 and a bottom plate 2) can be increased, and the connection and fixation can be achieved through the connection method of the clamping plate 4 and the clamping groove 5;

[0044] After the overall connection is completed, during use, a temperature sensor can be set inside the chassis. When the temperature sensor senses an increase in temperature, the transfer pump 43 can be started to form a closed-loop circulation of the coolant inside the chassis. Thus, by the flow of the coolant, heat can be better absorbed and dissipated, achieving a cooling effect;

[0045] When the temperature is higher than the set value, the transfer pump 43 pumps at high power. The flow rate of the transfer pump 43 is greater than the flow rate of the return hole 45 for return flow. There will be a backlog of coolant in the heat dissipation groove 6, resulting in an increase in internal pressure. This increase in pressure can overcome the elasticity of the third spring 43 and squeeze the third adjusting plate 39 outward, so that the coolant can flow out from the shunt groove 27 and enter the spraying mechanism. The water pressure of the coolant increases, causing the spraying disc 28 to separate from the connecting disc 29, enabling the spraying disc 28 to be further away from the connecting disc 29. In this way, when the spraying disc 28 sprays, it can spray a wider range in this area. At the same time, the spraying holes 37 are directed towards the inner wall of the chassis. Such spraying can always keep the coolant towards the set inner wall area of the chassis when the chassis is placed at various angles. Thus, in the form of rotating spraying of the coolant, it is sprayed onto the surface of the set area, combined with the original cooling fan, so as to dissipate heat more quickly in a timely manner.

[0046] In this application, the spraying mechanism can also be set in some places inside the chassis where spraying and cooling can be carried out, and the spraying mechanism is fixed. Then, using a hose, the shunt groove 27 is connected to the shunt pipe 35. In this way, the inside of the chassis can be better sprayed and cooled.
