Description

Technical Field

[0001] This invention belongs to the field of server cooling technology, specifically a cooling structure for mobile communication base station servers. Background Technology

[0002] Mobile communication base station servers, as core equipment of communication networks, are often deployed in outdoor computer rooms, base station cabins, and other scenarios. Moisture and dust in the environment can easily cause short circuits, oxidation, or blockage of heat dissipation channels in their internal electronic components. Therefore, the server casing needs to be designed as a closed structure to isolate external contaminants and ensure stable operation of components. However, a closed casing will block the natural heat exchange between the inside and the outside. When the server is running, the electronic components continuously generate heat. If the heat cannot be dissipated, it will lead to performance degradation or even shutdown. Therefore, an active cooling system is required. The mainstream coolant cooling solution is a system consisting of a storage tank, heat exchange plate, and circulating water pump. The heat exchange plate absorbs the heat inside the casing, and then the circulating coolant carries away the heat to achieve stable cooling.

[0003] In this cooling system, a certain amount of space must be reserved in the coolant storage tank, and it cannot be completely filled. This is because if the coolant is filled to the brim, the coolant will generate excessive pressure when it expands due to heat, which may cause the storage tank to rupture and the pipe joints to leak. At the same time, the coolant will carry air and form bubbles during circulation. The reserved space allows the bubbles to gather and be discharged, preventing the bubbles from accumulating and forming air blockages that would block the coolant circulation.

[0004] Some heat exchange plates are exposed above the coolant surface and cannot directly contact the coolant, resulting in a significant reduction in the effective heat exchange area and a marked decrease in heat exchange efficiency. Furthermore, there is a significant temperature difference between the heat exchange plates above and below the coolant surface. The heat exchange plates below the coolant surface can efficiently transfer heat, while the heat exchange plates above the coolant surface can only dissipate heat indirectly through the air inside the coolant storage tank, forming localized hot zones. This results in uneven heat exchange, seriously affecting the stability of the cooling system and making it difficult to meet the heat dissipation requirements of the base station server during continuous high-load operation.

[0005] Therefore, the present invention provides a cooling structure for a mobile communication base station server. Summary of the Invention

[0020] Preferably, the upper end of the control shaft extends to the outer wall of the exhaust hood and is fixedly mounted with a transmission disc. A connecting seat is fixedly mounted on the upper end face of the transmission disc, and a pressing rod for pressing the elastic strip is rotatably mounted on the outer wall of the connecting seat via a torsion spring.

[0021] A limit block is fixedly installed on the outer wall of the top pressure rod, and a blocking block for blocking the limit block is fixedly installed on the outer wall of the connecting seat.

[0022] Preferably, a control cylinder is fixedly installed on the inner wall of the storage box, and the inner cavity of the control cylinder is connected to the inner cavity of the guide tube;

[0025] Preferably, the inner wall of the storage box is elastically fitted with a sealing plug, which is made of elastic material and has a conical structure;

[0026] The axial end of the spray pipe is provided with a tapered hole that is compatible with the sealing plug;

[0030] The beneficial effects of this invention are as follows:

[0031] 1. This invention addresses the pain points of cooling systems by incorporating a circulating water pump, backflush pipe, spray pipe, exhaust hood, elastic plate, guide plate, and buried storage tank. The buried storage tank conducts heat to the soil, strengthening the heat dissipation foundation. The circulating water pump drives the coolant flow, and the drain hole of the backflush pipe aligns with the gaps between the heat exchange plates, causing the coolant to surge within the gaps, breaking up the stagnant liquid film on the surface of the heat exchange plates, increasing the contact frequency between the liquid and the plates, and mixing hot and cold liquids to prevent localized overheating. When the spray pipe sprays water upwards, the corresponding elastic plate vibrates upon impact, breaking the water column into fine droplets. Combined with the exhaust hood, these droplets are dispersed, ensuring that the coolant fully covers the heat exchange plates above the liquid surface, eliminating heat exchange gaps and reducing water film resistance. The guide plate can adjust the exhaust direction, adapting to multiple parallel heat exchange plates, ensuring that each plate contacts the droplets. Overall, this significantly improves heat exchange efficiency and uniformity, ensuring the stability of the cooling system and meeting the continuous high-load heat dissipation requirements of base station servers.

[0032] 2. This invention further optimizes the cooling effect by incorporating a guide plate, a tapping ball, a sealing plug, and a control cylinder. The guide plate, connected to a connecting plate and a pin shaft, can rotate synchronously to adjust the exhaust direction, ensuring that the airflow evenly covers multiple heat exchange plates. The tapping ball, linked with the elastic strip and the pressure rod, periodically taps the elastic plates, making the droplets smaller and more dispersed, preventing aggregation that could affect heat exchange. The sealing plug, in conjunction with a sector gear, causes the water pressure in the spray pipe to change back and forth, reducing stagnant liquid film and improving the dynamic contact between the liquid plates. The sliding plug inside the control cylinder, linked with the transmission sleeve, drives the guide plate to deflect back and forth using water pressure changes, synchronously adapting to airflow guidance and droplet distribution. Simultaneously, the buffer cylinder balances the air pressure in the storage tank. Overall, this significantly improves the heat exchange adaptability and stability, meeting the high-load heat dissipation requirements of base station servers. Attached Figure Description

Detailed Implementation

[0044] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0045] like Figures 1 to 9 As shown, the cooling structure for a mobile communication base station server according to the present invention includes a server shell 1, a circulation mechanism, a heat exchange mechanism, a turbulence mechanism, a spray mechanism, an air supply mechanism, and a control mechanism. The server of the mobile communication base station is located inside the server shell 1. The core functional components and functions of the mobile communication base station server are as follows: the baseband processing module is the core, responsible for processing the uplink and downlink signals between the mobile phone and the core network, completing protocol conversion and data encoding and decoding; the radio frequency module converts the baseband signal into a radio frequency signal and amplifies and transmits it, while receiving the mobile phone signal feedback; the interface and transmission module connect to the core network and other base stations through optical ports and network ports to realize data interaction; and the power supply provides stable power to ensure continuous operation of the equipment.

[0046] The server casing 1 has an external door that can be opened and closed. When the door is closed, it can form a closed space inside, preventing moisture in the air from entering the interior of the server casing 1, thereby preventing external moisture from affecting the use of the electronic components inside the server casing 1.

[0047] The circulation mechanism includes a heat exchange box 2 and a circulation duct 3 with a built-in circulation fan. The inner cavity of the heat exchange box 2 is connected to the inner cavity of the server shell 1 through the circulation duct 3. The heat exchange box 2 is installed on the outer wall of the server shell 1, and the circulation duct 3 controls the air circulation flow inside the heat exchange box 2 and the server shell 1.

[0048] The heat exchange mechanism includes a heat exchange plate 10 and a storage tank 4 for storing coolant. The heat exchange plate 10 is located between the heat exchange box 2 and the storage tank 4. The heat exchange plate 10 is made of common copper plate, with one end located inside the storage tank 4 and the other end located on the inner wall of the heat exchange box 2.

[0049] Air circulates inside the heat exchange box 2 and the server casing 1, and heat in the gas is transferred to the coolant inside the storage box 4 through the heat exchange plate 10. The storage box 4 is buried underground, so that the coolant can transfer heat into the soil.

[0050] The turbulence mechanism includes a circulating water pump 7 and a drain pipe 14. The output end of the circulating water pump 7 is connected to the storage tank 4 through the drain pipe 14. The circulating water pump 7 is fixedly installed on the outer wall of the storage tank 4. The input end of the circulating water pump 7 is located in the inner cavity of the storage tank 4. The circulating water pump 7 draws the coolant from the inner cavity of the storage tank 4 and then discharges it through the drain pipe 14, thus disturbing the flow of coolant inside the storage tank 4.

[0051] The circulating water pump 7 can drive the coolant in the storage tank 4 to flow actively, avoiding the stratification of coolant temperature under natural convection, making the coolant temperature in each area of ​​the storage tank 4 more uniform, ensuring that the coolant in contact with the heat exchange plate 10 always has a stable temperature difference. At the same time, the flowing coolant can make more full contact with the surface of the heat exchange plate 10, reducing the heat exchange resistance caused by liquid film adhesion and improving heat transfer efficiency. In addition, the circulating flow can also remove the air bubbles generated during the heat exchange process and flush away impurities that may be deposited on the surface of the heat exchange plate 10, avoiding air resistance and impurity blockage from affecting the heat exchange effect of the heat exchange plate 10, and ensuring the continuous and stable operation of the entire heat exchange.

[0052] The spraying mechanism includes a guide pipe 13 and a spray pipe 16. The spray pipe 16 is connected to the drain pipe 14 through the guide pipe 13. A nozzle is provided on the outer wall of the spray pipe 16. One end of the guide pipe 13 is connected to the drain pipe 14 and the other end is connected to the spray pipe 16. When the circulating water pump 7 is working, the nozzle on the outer wall of the spray pipe 16 sprays coolant upwards.

[0053] The air supply mechanism includes a control pump 5 and an exhaust hood 6. The control pump 5 draws gas from the inner cavity of the storage tank 4 and discharges it through the exhaust hood 6. The control pump 5 is a common circulating air pump. Its input end is connected to the inner cavity of the storage tank 4, and its output end is connected to the exhaust hood 6. It is used to draw gas from the upper part of the storage tank 4 (in order to prevent the storage tank 4 from being damaged due to changes in coolant temperature, air needs to be reserved when injecting coolant into the storage tank 4), and then discharges it into the inner cavity of the storage tank 4 through the exhaust hood 6 to form an air circulation. It should be noted that the exhaust hood 6 is always located above the coolant level.

[0054] The spray nozzles outside the spray pipe 16 are located directly below the exhaust end of the exhaust hood 6, which faces the heat exchange plate 10. When the spray pipe 16 discharges coolant upwards, the exhaust hood 6 simultaneously exhausts coolant towards the portion of the heat exchange plate 10 above the coolant surface, thus dispersing the water droplets or columns discharged from the spray pipe 16. Compared to intact water droplets, the dispersed droplets have a significantly increased contact area with the upper part of the heat exchange plate 10, which can fully cover the tiny gaps and uneven surfaces of the plate, avoiding heat exchange blank areas. At the same time, the small droplets are less likely to accumulate and form a stagnant water film after contact, and can continuously carry away heat in a dynamic thin-layer flow state, eliminating the heat exchange resistance caused by the water film. In addition, the impact force of the small droplets is more dispersed and gentle, which can reduce local wear on the upper part of the heat exchange plate 10, and can quickly integrate into the circulation, avoiding local corrosion caused by long-term stagnation, and extending the service life of the heat exchange plate 10.

[0055] The control mechanism includes a guide plate 27 and an elastic plate 19. The guide plate 27 is rotatably installed inside the exhaust hood 6. Rotating the guide plate 27 adjusts the exhaust direction of the exhaust hood 6. Multiple heat exchange plates 10 are provided, and two adjacent heat exchange plates 10 are parallel to each other. By adjusting the exhaust direction of the exhaust hood 6, small water droplets can be discharged to different positions on the surface of the heat exchange plates 10.

[0056] The elastic plate 19 is fixedly installed on the outer wall of the exhaust hood 6 and faces the spray pipe 16. The spray pipe 16 discharges water columns toward the elastic plate 19. When the elastic plate 19 is struck, it vibrates, which breaks the concentrated water column into smaller and more evenly distributed droplets. Compared with simple static impact, vibration can prevent the droplets from quickly re-aggregating after impact and maintain a dispersed state for a long time. At the same time, these small and dispersed droplets are more likely to enter the gap between the heat exchange plates 10 with the airflow guided by the exhaust hood 6, evenly covering the surface of each heat exchange plate 10, optimizing the droplet dispersion effect, and helping to achieve uniform heat exchange.

[0057] The drain pipe 14 is fixedly installed on the bottom surface of the storage tank 4. The backflush pipe 15 is fixedly installed on the side wall of the drain pipe 14. The backflush pipe 15 has a drain hole on the side facing the heat exchange plate 10. When the circulating water pump 7 is working, part of the coolant is discharged through the spray pipe 16 and the other part is discharged through the backflush pipe 15.

[0058] The drain hole is aligned with the gap between two adjacent heat exchange plates 10. The drain hole is located below the coolant surface. When the circulating water pump 7 is working, it controls the coolant to surge within the gap between the two adjacent heat exchange plates 10. The alignment of the drain hole with the gap allows the coolant delivered by the circulating water pump 7 to accurately enter the key heat exchange area between the heat exchange plates 10, avoiding heat exchange gaps caused by liquid flow dispersion. The surge of coolant can break the stagnant liquid film that is easily formed on the surface of the heat exchange plates 10, greatly increasing the contact area and frequency of the liquid plates, accelerating heat transfer. At the same time, the surge can drive the hot and cold coolant in the gap to mix fully, balance the temperature of each area, and prevent local overheating.

[0059] In a preferred embodiment of the present invention, a control shaft 29 is rotatably mounted on the inner wall of the exhaust hood 6, and a guide plate 27 is fixedly connected to the outer wall of the control shaft 29. Rotating the control shaft 29 drives the guide plate 27 to rotate. Multiple guide plates 27 are provided to facilitate the adjustment of the exhaust direction at different positions inside the exhaust hood 6.

[0060] The inner wall of the exhaust hood 6 is provided with a connecting plate 28, and the outer wall of the connecting plate 28 is provided with a waist-shaped groove. The outer wall of the guide plate 27 is fixedly installed with a pin that slides with the waist-shaped groove. Multiple guide plates 27 are connected through the connecting plate 28. When one guide plate 27 rotates, the other guide plates 27 rotate synchronously through the cooperation of the waist-shaped groove and the pin, so as to guide the airflow when the exhaust hood 6 exhausts.

[0061] A baffle 11 is fixedly installed on the upper end face of the exhaust hood 6. The elastic plate 19 is located inside the baffle 11. The baffle 11 is set to prevent the water column discharged from the spray pipe 16 from being too high and affecting the water column dispersion effect. At the same time, the water column impacting the baffle 11 is guided through the elastic plate 19 so that the water column can be dispersed when the elastic plate 19 vibrates.

[0062] An elastic strip 23 is fixedly installed on the outer wall of the exhaust hood 6. A striking ball 24 is fixedly installed on one end of the elastic strip 23. The outer wall of the striking ball 24 is in contact with the outer wall of the elastic plate 19. The elastic strip 23 is pulled to make the striking ball 24 move away from the elastic plate 19. Then the elastic strip 23 is released, and the striking ball 24 strikes the surface of the elastic plate 19, thereby causing the elastic plate 19 to vibrate.

[0063] When the control guide plate 27 rotates, the adjustment control shaft 29 reciprocates. The upper end of the control shaft 29 extends to the outer wall of the exhaust hood 6 and is fixedly installed with a transmission disc 22. When the control shaft 29 reciprocates, it drives the transmission disc 22 to reciprocate.

[0064] A connecting seat 35 is fixedly installed on the upper end face of the transmission disc 22. When the transmission disc 22 deflects, it drives the connecting seat 35 to move synchronously. The outer wall of the connecting seat 35 is rotatably mounted with a pressing rod 25 for pressing the elastic strip 23 through a torsion spring. The elastic force of the torsion spring controls the pressing rod 25 to maintain a vertical state in real time.

[0065] A limiting block 36 is fixedly installed on the outer wall of the top pressure rod 25, and a blocking block 20 for blocking the limiting block 36 is fixedly installed on the outer wall of the connecting seat 35. The rotation direction of the top pressure rod 25 is restricted by the setting of the limiting block 36 and the blocking block 20.

[0066] When the transmission disc 22 rotates in the forward direction, the top pressure rod 25 presses against the elastic strip 23, causing the striking ball 24 to move away from the elastic plate 19 until the elastic plate 19 and the top pressure rod 25 separate. At this time, the striking ball 24 strikes the elastic plate 19. At this time, the blocking block 20 blocks the limiting block 36, and the top pressure rod 25 remains in a vertical state so that the top pressure rod 25 can move the elastic strip 23 to a sufficient distance. When the transmission disc 22 rotates in the reverse direction, until the outer wall of the top pressure rod 25 is in contact with the outer wall of the elastic strip 23, the transmission disc 22 continues to rotate in the reverse direction. At this time, the top pressure rod 25 deflects until the top pressure rod 25 moves to the other side of the elastic strip 23 again so that the elastic strip 23 can be moved again.

[0067] In a preferred embodiment of the present invention, a control cylinder 12 is fixedly installed on the inner wall of the storage box 4. The inner cavity of the control cylinder 12 is connected to the inner cavity of the guide tube 13. The inner cavity of the control cylinder 12 and the inner cavity of the guide tube 13 are connected by a conduit.

[0068] The inner cavity of the control cylinder 12 is elastically fitted with a sliding plug 34. When the pressure inside the guide tube 13 increases, the sliding plug 34 slides upward, and when the pressure inside the guide tube 13 decreases, the sliding plug 34 slides downward.

[0069] A sliding rod 26 is fixedly installed on the upper end face of the sliding plug 34, and a transmission sleeve 32 is fixedly installed on the upper end face of the sliding rod 26. By controlling the pressure change in the inner cavity of the guide tube 13, the sliding plug 34 is controlled to slide back and forth. The sliding rod 26 is a hexagonal prism and is slidably connected to the inner wall of the control cylinder 12.

[0070] The inner wall of the transmission sleeve 32 is provided with a spiral groove 31. When the slide rod 26 slides back and forth, it drives the transmission sleeve 32 to slide back and forth. The bottom of the control shaft 29 extends to the bottom of the exhaust hood 6 and is fixedly installed with a transmission shaft 33. Rotating the transmission shaft 33 drives the control shaft 29 to rotate.

[0071] The radial outer wall of the drive shaft 33 is fixedly equipped with balls 30 that slide with the spiral groove 31. When the drive sleeve 32 slides back and forth, the ball 30 and the spiral groove 31 cooperate to control the reciprocating deflection of the drive shaft 33, thereby driving the control shaft 29 and the guide plate 27 to deflect synchronously.

[0072] The inner wall of the storage box 4 is elastically fitted with a sealing plug 21. The sealing plug 21 is made of elastic material and has a conical structure. In this embodiment, the sealing plug 21 is made of elastic rubber material.

[0073] The axial end of the spray pipe 16 is provided with a conical hole adapted to the sealing plug 21. When the circulating water pump 7 is working, the sealing plug 21 slides back and forth, causing the conical hole to open and close repeatedly. When the conical hole is closed, the water pressure inside the guide pipe 13 increases. When the conical hole is open, some of the coolant inside the spray pipe 16 is discharged through the conical hole, thereby reducing the water pressure in the guide pipe 13. This drives the slide rod 26 and the sliding plug 34 to slide back and forth, thereby controlling the guide plate 27 to deflect back and forth, realizing the guidance of the exhaust hood 6. At the same time, it can also control the striking ball 24 to strike the elastic plate 19.

[0074] In addition, as the conical hole opens and closes repeatedly, the water pressure of the spray pipe 16 changes repeatedly. When the water pressure changes repeatedly, the coolant discharged from the spray pipe 16 will exhibit an alternating flow state of strong and weak. The repeated water pressure can also reduce the probability of the coolant forming a stable stagnant liquid film on the surface of the heat exchange plate 10. Through periodic impact and coverage, the dynamics of the liquid plate contact are improved, ultimately enhancing the overall heat exchange efficiency and uniformity.

[0075] A buffer cylinder 9 is fixedly installed on the outer wall of the storage box 4. A buffer plug 8 is elastically installed in the inner cavity of the buffer cylinder 9. The buffer plug 8 is connected to the inner cavity of the buffer cylinder 9 by a spring. The inner cavity of the buffer cylinder 9 is connected to the inner cavity of the storage box 4, thereby adapting to the air pressure changes in the inner cavity of the storage box 4.

[0076] A connecting rod is fixedly installed at the end of the sealing plug 21 away from the spray pipe 16. One end of the connecting rod extends to the outer wall of the storage box 4 and is fixedly installed with a transmission rack 17. The connecting rod passes through the outer wall of the storage box 4. A floating sealing plug is provided on the outer wall of the connecting rod so that the inner cavity of the storage box 4 can be kept sealed when the connecting rod slides.

[0077] The control pump 5 is fixedly installed on the outer wall of the storage tank 4, and the output shaft of the motor built into the control pump 5 is fixedly installed with a sector gear 18. The sector gear 18 meshes with the transmission rack 17. When the control pump 5 delivers gas, the motor inside controls the sector gear 18 to rotate, which, in conjunction with the elastic force on the sealing plug 21, controls the transmission rack 17 and the sealing plug 21 to slide back and forth, thereby causing the conical hole to open and close back and forth.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
