Description

Technical Field

[0001] The present invention relates to the technical field of blown plate structures, and specifically to a blown plate structure applied to a base station. Background Art

[0002] With the development of society, high-speed, low-latency, and large-connection information transmission has gradually been applied to various data transmission fields, such as 5G applications in AR / VR remote collaborative design, remote control, AR-assisted assembly, machine vision, AGV logistics, autonomous driving, and ultra-high-definition video. The main advantages of 5G information transmission lie in its large transmission bandwidth and low latency: its maximum bandwidth is up to 10 Gbit / s, with a large amount of data transmitted, which is 100 times that of 4G; the network latency is less than 1 millisecond, while that of 4G is 30 - 70 milliseconds.

[0003] 5G information transmission relies on base station equipment. The internal structure of the base station equipment mainly includes: BBU, radio frequency (RF) unit, power amplifier (PA), main power supply, antenna interface, heat dissipation system, etc. Due to the need to process a large amount of data, the transmission rate needs to be increased exponentially, resulting in a gradual increase in the power consumption of the BBU and AUU of 5G base stations. The power consumption of 5G base stations has also reached 2.5 - 3.5 times that of 4G base stations. Therefore, a radiator is required, which requires uniform temperature distribution, small surface temperature difference, and strong heat dissipation performance to reduce the temperature difference between the chip and the shell.

[0004] Therefore, the blown plate was developed and set up. However, the upper cover and the lower cover corresponding to the existing blown plate array are both made of die-castings. The overall manufacturing cost is high, and the components are all solid shells, resulting in a large weight of the entire blown plate structure. When the base station is set up at a high altitude, a more solid base station shell needs to be erected. Moreover, since it and the components are both die-cast, the distribution of its entire flow channel is not uniform enough, resulting in relatively poor heat dissipation uniformity. For this reason, there is an urgent need to develop a blown plate structure that can reduce the overall weight and has more uniform and reliable heat dissipation. Summary of the Invention

[0005] In view of the above problems, the present invention provides a blown plate structure applied to a base station, which can reliably reduce weight and has uniform and reliable heat dissipation.

[0006] A blown plate structure applied to a base station, characterized in that it includes:

[0007] Several groups of blown plate bodies, each group of blown plate bodies is formed by splicing two oppositely arranged blown sheets. The formed blown plate body includes a steam channel inlet, an internal variable cavity, and a condensation channel outlet. The internal variable cavity includes several groups of interconnected flow channels. The steam channel inlet is connected to the condensation channel outlet through the internal variable cavity. The steam channel inlet and the condensation channel outlet are both at the bottom and are arranged with downward openings;

[0008] A cover plate, on the surface of which there are several arranged slots, and each group of slots is used for inserting a corresponding blown plate body;

[0009] A fin plate, in the inner cavity of which there are several groups of FINS, and their combination forms a FIN assembly. The outer periphery of the FIN assembly is wrapped by a housing. The housing has a steam discharge notch opened below the width direction area corresponding to the steam channel inlet, and the inside is a FIN with both upper and lower surfaces open. The housing has a condensation reflux notch opened below the width direction area corresponding to the condensation channel outlet, and the inside is a FIN with both upper and lower ends open;

[0010] And a lower heat conducting plate, which is used to fit the heat source;

[0011] All the blown plate bodies are vertically arranged and parallelly arranged at equal intervals to form a blown plate assembly. The cover plate is located directly below the blown plate assembly. The bottom of each blown plate is inserted into the corresponding position of the slot of the cover plate. The lower surface of the cover plate is arranged closely against the upper surface of the housing of the fin plate. The steam discharge notch is communicated with the steam channel inlet of each blown plate body directly above. The condensation reflux notch is communicated with the condensation reflux notch of each blown plate body directly above. The inner cavity of the fin plate stores a refrigerant medium. The upper surface of the lower heat conducting plate is closely against the lower surface of the housing of the fin plate.

[0012] It is further characterized in that:

[0013] It further includes a connecting frame plate, which covers and is fixedly connected to the upper surface of the blown plate assembly to ensure the overall structure of the blown plate assembly is stable and reliable;

[0014] On one side of the internal cavity with different shapes corresponding to the steam channel inlet, there are several groups of flow channels arranged obliquely upward from bottom to the condensation channel outlet side. Above the position corresponding to the condensation channel outlet in the internal cavity with different shapes, there are several groups of labyrinth flow channels;

[0015] The steam channel inlet and the condensation channel outlet are respectively arranged at both ends of the bottom length direction area of the blown plate body. The length of the steam channel inlet is greater than the length of the condensation channel outlet;

[0016] Each slot of the cover plate is arranged in a shape following the profile of the lower end face of the blown plate body. The slot includes a positioning profile groove and an inlet / outlet profile groove. The positioning profile groove is used for fixedly inserting and connecting the lower convex plate of the blown plate body. The inlet / outlet profile groove includes a steam channel inlet profile groove and a condensation channel outlet profile groove. The outer contour of the steam channel inlet is embedded in the steam channel inlet profile groove, and the outer contour of the condensation channel outlet is embedded in the condensation channel outlet profile groove;

[0017] The connection positions between the slots and each set of inflation plate bodies are welded to ensure the secure installation and reliable sealing of the cover plate and the inflation plate bodies;

[0018] The lower heat conducting plate further includes an upwardly convex frame retaining strip. The fin plate is embedded in the central inner cavity formed by the frame retaining strip. The outer periphery of the fin plate and the frame retaining strip form a medium return channel. Notch grooves are provided at both ends of the housing corresponding to the steam discharge notch. The housing at the outer end of the flow direction of the FIN corresponding to the condensation return notch is open. The refrigerant medium enters the internal FIN area along the condensation return notch, then flows along the FIN area to the medium return channel, and then flows into the notch groove through the return channel. Since the FIN in the notch groove has open upper and lower surfaces, the return is reliable and smooth;

[0019] The fin plate is composed of a combination of a first fin plate and a second fin plate. The first fin plate is the fin plate corresponding to the area below the steam channel inlet, and the second fin plate is the fin plate corresponding to the area below the condensation channel outlet. The lower heat conducting plate is provided with a cavity retaining strip in the interval area between the two sets of fin plates. The cavity retaining strip enables reliable return operation of the return channel;

[0020] The cavity retaining strip is composed of several discontinuous segments, and there is an interval between adjacent cavity retaining strips. The FIN channels of the two fin plates communicate with each other at the interval position to ensure that part of the medium flows and mixes with each other;

[0021] The surface area of the cover plate covers the entire upper surface formed by the frame retaining strip of the lower heat conducting plate, and at the same time covers and fits the upper surfaces of the shells of the first fin plate and the second fin plate.

[0022] After adopting the above technical solution, the steam discharge notch is arranged directly above the heat source. The structure for storing the refrigerant medium is the fin plate. The fin plate is placed in the cavity formed by the stamping-molded cover plate and the lower heat conducting plate and is formed by the aluminum brazing process. Its manufacturing process is simple, the processing production cost is low, and it is easy to process. When the heat source is in the working state, heat is generated. Due to the temperature difference between the heat source and the lower heat conducting plate, heat will transfer from the high-temperature object to the low-temperature object, and the heat is absorbed by the lower heat conducting plate. The gaseous refrigerant medium directly above the heat source position is heated and accelerated in circulation, enters the flow channels of the internal heterogeneous cavities of each inflation plate body through the corresponding positions of the slots on the cover plate. Since the two side surfaces of the sealed inflation plate body are in convection with the air in the base station, condensation occurs, and then it flows back to the corresponding FIN through the condensation channel outlet. After that, the refrigerant medium in the FIN in the condensation channel outlet area flows back to the FIN corresponding to the steam channel inlet area in an orderly manner, enabling the refrigerant medium to flow regularly and orderly. This process repeats continuously, thereby improving the heat exchange efficiency and reducing the working temperature of the heat source. Description of the Drawings

Detailed implementation manners

[0033] An expansion plate structure applied to a base station, as shown in Figures 1-8 , which includes: several groups of main bodies of the expansion plate 10, cover plates 20, fin plates 30, and lower heat conducting plates 40;

[0034] Each inflatable plate body 10 is formed by splicing two oppositely arranged inflatable sheets 11. The formed inflatable plate body 10 includes a steam channel inlet 12, an internal variable cavity 13, and a condensation channel outlet 14. The internal variable cavity 13 includes several groups of interconnected flow channels. The steam channel inlet 12 is connected to the condensation channel outlet 14 through the internal variable cavity 13. Both the steam channel inlet 12 and the condensation channel outlet 14 are at the bottom and are arranged with downward openings.

[0035] A number of arranged slots 21 are distributed on the surface of the cover plate 20. Each group of slots 21 is used for inserting the corresponding inflatable plate body 10.

[0036] Several groups of FINS are arranged in the inner cavity of the fin plate 30, and they are combined to form a FIN assembly. The outer periphery of the FIN assembly is wrapped by a housing 301. The housing 301 is provided with a steam discharge notch 302 below the width direction area corresponding to the steam channel inlet 12, and the inside is a FIN with both upper and lower surfaces open. The housing 301 is provided with a condensation reflux notch 303 below the width direction area corresponding to the condensation channel outlet 13, and the inside is a FIN with both upper and lower ends open.

[0037] The lower heat conducting plate 40 is used to fit the heat source 50. The heat source 50 is generally a BBU, AUU, and power module on the base station.

[0038] In a specific embodiment, all the inflatable plate bodies 10 are arranged vertically and arranged in parallel at equal intervals to form an inflatable plate assembly 60. The cover plate 20 is directly below the inflatable plate assembly 60. The bottom of each group of inflatable plates 10 is inserted into the corresponding position of the slot 21 of the cover plate 20. The lower surface of the cover plate 20 is arranged closely against the upper surface of the housing 301 of the fin plate 30. The center area of the steam channel inlet 12 of each group of inflatable plate bodies 10 is connected above the steam discharge notch 302. The condensation reflux notch 13 of each group of inflatable plate bodies 10 is connected above the condensation reflux notch 303. The inner cavity of the fin plate 20 stores a refrigerant medium. The upper surface of the lower heat conducting plate 40 is closely against the lower surface of the housing 301 of the fin plate 30. In a specific embodiment, the refrigerant medium is Ra134 refrigerant, which is a gas refrigerant medium.

[0039] During specific implementation, a connecting frame plate 70 is further included. The connecting frame plate 70 covers the upper surface of the inflatable plate assembly 60 and is fixedly connected to ensure the overall structure of the inflatable plate assembly 60 is stable and reliable. The connecting frame plate 70 is a plate structure, and a hollow area 71 is provided thereon to ensure the overall mass is relatively light.

[0040] On one side of the internal cavity with different shapes 13 corresponding to the steam channel inlet 12, several groups of flow channels 131 are arranged obliquely upward from bottom to the side of the condensation channel outlet. Above the position corresponding to the condensation channel outlet 14 in the internal cavity with different shapes 13, several groups of labyrinth flow channels 132 are arranged, which ensure that the steam flows through a sufficiently large area as much as possible during circulation, ensuring sufficient and reliable heat exchange;

[0041] The steam channel inlet 12 and the condensation channel outlet 14 are respectively arranged at both ends of the bottom length direction of the blow molding plate body 10. The length of the steam channel inlet 12 is greater than the length of the condensation channel outlet 14. In specific implementation, the length of the steam channel inlet 12 is about 4 times the length of the condensation channel outlet 14.

[0042] In specific implementation, each group of slots 21 of the cover plate 20 are respectively arranged in a shape imitation corresponding to the lower end face of the blow molding plate body 10. The slot 21 includes a positioning shape imitation groove 22 and an entrance and exit shape imitation groove 23. The positioning shape imitation groove 22 is used for fixedly inserting and connecting the lower convex plate 101 of the blow molding plate body 10. The entrance and exit shape imitation groove 23 includes a steam channel inlet shape imitation groove 231 and a condensation channel outlet shape imitation groove 232. The outer contour of the steam channel inlet 12 is embedded in the steam channel inlet shape imitation groove 231, and the outer contour of the condensation channel outlet 14 is embedded in the condensation channel outlet shape imitation groove 232;

[0043] The connection position between the slot 21 and each group of blow molding plate bodies 10 is welded, ensuring the tight installation and reliable sealing between the cover plate 20 and the blow molding plate body 10;

[0044] The lower heat conducting plate 40 further includes an upward convex frame retaining strip 41. The fin plate 30 is embedded in the central inner cavity formed by the frame retaining strip 41. The outer periphery of the fin plate 30 and the frame retaining strip 41 form a medium return channel 80. Notch grooves 304 are provided at both ends of the housing 301 corresponding to the steam discharge notch 302. The housing corresponding to the outer end of the flow direction of the FIN of the condensation return notch 303 is open. The refrigerant medium enters the internal FIN area along the condensation return notch 303, then flows along the FIN area to the medium return channel 80, and then flows into the notch groove 304 through the return channel 80. Since the FIN in the notch groove 304 has open upper and lower surfaces, the return is reliable and smooth.

[0045] In specific implementation, for the convenience of assembly, the fin plate 30 is composed of a first fin plate 31 and a second fin plate 32 combined. The first fin plate 31 is the fin plate corresponding to the area below the steam channel inlet 12, and the second fin plate 32 is the fin plate corresponding to the area below the condensation channel outlet 14. The lower heat conducting plate 40 is provided with a cavity retaining strip 42 corresponding to the interval area between the two groups of fin plates. The cavity retaining strip 42 enables the reliable return operation of the return channel 80.

[0046] The cavity bar 42 is composed of several discontinuous segments, and there is a gap 43 between adjacent cavity bars 42. The FIN channels of the two fin plates communicate with each other at the position of the gap 43, ensuring that part of the medium flows and mixes with each other.

[0047] The surface area of the cover plate 20 covers the entire upper surface formed by the surrounding frame bar 41 of the lower heat conducting plate 40, and at the same time, it covers and fits the upper surfaces of the shells of the first fin plate 31 and the second fin plate 32.

[0048] During specific implementation, the surface area of the steam discharge notch 302 is set corresponding to the arrangement areas of several heat sources, ensuring that the heat dissipated by the heat sources can easily pass through the lower steam discharge notch 302 in time to spread the heat into the inside of the blown plate body.

[0049] Its working principle is as follows. The steam discharge notch is arranged directly above the heat source. The structures for storing the refrigerant medium are the first fin plate and the second fin plate. The first fin plate and the second fin plate are placed in the cavity formed by the stamping-molded cover plate and the lower heat conducting plate and are formed by the aluminum brazing process. Its manufacturing process is simple, the processing production cost is low, and it is easy to process. When the heat source is in the working state, heat is generated. Due to the temperature difference between the heat source and the lower heat conducting plate, the heat will transfer from the high-temperature object to the low-temperature object. The heat is absorbed by the lower heat conducting plate, and the gaseous refrigerant medium in the first fin plate is heated and accelerated to circulate. The heated steam enters the flow channels of the internal cavities of each blown plate body through the profiling grooves at the steam channel inlets of the cover plate. Since the two side surfaces of the sealed blown plate body are in convection with the air in the base station, condensation occurs, and then it flows back to the FIN of the second fin plate through the condensation channel outlet. After that, the refrigerant medium in the second fin plate flows back to the first fin plate in an orderly manner, making the refrigerant medium flow regularly and orderly. This process repeats continuously, thereby improving the heat exchange efficiency and reducing the working temperature of the heat source.

[0050] The upper and lower positional relationships mentioned in the text are only the relative positional relationships during the manufacture of the entire blown plate structure. During specific use, according to the distribution of the heat sources and the reasonable requirements of the space, the entire blown plate structure can be placed upside down, making the original lower part become the upper part. At the same time, the entire blown plate structure can be placed vertically, making the lower heat conducting plate become a vertical heat conducting plate.
