[0021] Embodiments of this application provide a combiner for a repeater, including a housing and a plurality of combiner units disposed opposite each other on both sides of the housing. The combiner further includes: A cover plate assembly includes a first cover plate and a second cover plate disposed opposite to the first cover plate; The fastening assembly includes a first fastener and a second fastener, wherein the first fastener is disposed on the first cover plate and the second fastener is disposed on the second cover plate; The housing has a fastening portion extending through the thickness direction of the housing, and each of the combiner units has a heating area on the side away from the housing; The first fastener can extend into one end of the fastening part, and the second fastener can extend into the other end of the fastening part, so that the first cover plate and the second cover plate are respectively disposed on opposite sides of the housing and respectively attached to the corresponding heating area, so that the heat of the heating area is transferred to the first cover plate and the second cover plate.

[0022] The aforementioned combiner for a repeater improves system integration by arranging multiple combiner units on both sides of the housing. An effective heat conduction path is formed by the close contact of a first and second cover plate with the heat-generating area of ​​each combiner unit. This double-sided cover plate structure ensures uniform heat distribution in both directions, effectively reducing energy loss caused by heat concentration and thus optimizing thermal management. By accelerating heat conduction from the heat-generating area to the cover plate, heat accumulation inside is avoided, reducing equipment losses and performance degradation caused by overheating.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] according to Figures 1-4 This application provides a combiner 100 for a repeater, including a housing 10 and a plurality of combiner units 20 disposed on opposite sides of the housing 10. The combiner also includes a cover plate assembly 30 and a fastening assembly 40.

[0025] The cover plate assembly 30 includes a first cover plate 31 and a second cover plate 32 disposed opposite to the first cover plate 31; the fastening assembly 40 includes a first fastener 41 and a second fastener 42, the first fastener 41 being disposed on the first cover plate 31 and the second fastener 42 being disposed on the second cover plate 32. The housing 10 has a fastening portion 11 extending through the thickness direction of the housing 10, and each of the combiner units 20 has a heating area 21 on the side away from the housing 10.

[0026] The first fastener 41 can extend into one end of the fastening part 11, and the second fastener 42 can extend into the other end of the fastening part 11, so that the first cover plate 31 and the second cover plate 32 are respectively disposed on opposite sides of the housing 10 and respectively fit with the corresponding heating area 21, so that the heat of the heating area 21 is transferred to the first cover plate 31 and the second cover plate 32.

[0027] Specifically, the combiner unit 20 is a high-frequency resonant cavity structure. The combiner housing 10 is the outer shell structure of the entire combiner, mainly used for supporting and protecting the internal components. Multiple combiner units 20 are provided inside the housing 10, and the combiner units 20 are arranged on both sides of the housing 10.

[0028] Distributing multiple combiner units 20 on both sides of the housing 10 effectively improves system integration. Compared to traditional single-sided combiner designs, the dual-sided design allows for more combiner units 20 to be efficiently arranged within a limited space, maximizing space utilization and thus improving the overall functionality and efficiency of the device. The dual-sided design also allows the combiner units 20 to be arranged more compactly within the housing 10, resulting in shorter and more efficient signal transmission paths and increased signal processing speed. Especially in scenarios requiring the processing of multiple high-frequency signals, rapid signal combining and transmission become crucial for improving operational efficiency.

[0029] Furthermore, the traditional single-sided combiner unit design of the housing 10 causes heat to concentrate on one side of the housing 10. However, this application distributes multiple combiner units 20 on both sides of the housing 10, allowing heat to be effectively dispersed on both sides of the housing 10. This enables the cover plates on both sides to effectively contact and conduct heat, thereby avoiding heat concentration on one side and reducing the risk of local overheating.

[0030] Because heat can be conducted and dispersed simultaneously from two directions, the heat dissipation path of the equipment is more uniform, and heat is rapidly conducted from the heat-generating area 21 of each combiner unit 20 to the cover assembly 30. During the heat conduction process, the heat is quickly diffused to the external cooling area through the cover. This structure not only optimizes heat dissipation performance but also reduces energy loss caused by heat accumulation, thereby improving working efficiency.

[0031] Each combiner unit 20 has a heat-generating area 21 located on the side away from the housing 10. These combiner units 20 function to combine and transmit multiple signals. The heat source of the combiner unit 20 is typically located inside the unit, thus generating heat during signal processing. Heat is conducted along the temperature gradient within the material from high-temperature regions to low-temperature regions, thus, when heat is generated, it is conducted to the far end of the housing 10, forming the heat-generating area 21.

[0032] The first cover plate 31 and the second cover plate 32 are respectively disposed corresponding to the combiner units 20 on both sides of the housing 10. The first cover plate 31 and the second cover plate 32 are respectively opposite to the two sides of the housing 10 and are tightly fitted to their respective heating areas 21. The function of the cover plate is to guide and conduct the heat of the heating area 21 to the outside, thereby achieving heat dissipation, and to seal the housing 10 through the cover plate.

[0033] Furthermore, the inner sides of the first cover plate 31 and the second cover plate 32 are in close contact with the heating area 21 of the combiner unit 20, forming an effective heat conduction path. This allows the heat generated by the combiner unit 20 to be quickly transferred to the cover plate assembly 30, thereby preventing heat accumulation and promoting heat dissipation to the outside.

[0034] Furthermore, both the first fastener 41 and the second fastener 42 are threaded nail structures. The fastening part 11 is a fastening hole 111 extending through the thickness direction on the housing 10. The fastening hole 111 cooperates with the threaded nail. The design of the fastener ensures the fixation of the cover plate and the thermal contact between the cover plate and the combiner unit 20. This structure allows the cover plate to be firmly connected to the housing 10 while maintaining the fit between the cover plate and the heating area 21 to achieve good heat conduction.

[0035] In summary, this embodiment, through the design of double-sided cover plates and fastening components 40, ensures the heat dissipation efficiency of the combiner, enabling heat to be evenly conducted to the cover plates on both sides, thereby significantly improving heat dissipation capacity and ensuring the stability and reliability of the equipment during long-term operation.

[0036] In one specific embodiment, the fastening part 11 is a fastening hole 111, and the first fastener 41 and the second fastener 42 are both fastening pins. The fastening pins can extend into the fastening hole 111 so that the housing 10 is fixed to the first cover plate 31 and the second cover plate 32 respectively.

[0037] Specifically, the fastening part 11 is provided with fastening holes 111, which are formed through the thickness direction of the housing 10, thereby providing an installation position for the fastening assembly 40 and ensuring that the fastening pin can fix the connection between the cover plate and the housing 10.

[0038] The fastening pin is connected to the housing 10 through the fastening hole 111, fixing the first cover plate 31 and the second cover plate 32 to opposite sides of the housing 10 respectively. This structural design can effectively ensure a tight connection between the cover plate and the housing 10 and ensure the structural stability of the combiner.

[0039] Furthermore, the insertion of the fastening pin into the fastening hole 111 ensures close contact between the first cover plate 31 and the second cover plate 32 and the housing 10, so that the heating area 21 of each combiner unit 20 can maintain good thermal conductivity contact with the inner side of the corresponding cover plate.

[0040] In one specific embodiment, the first cover plate 31 has a first contact surface 311 on the side facing the housing 10; the second cover plate 32 has a second contact surface 321 on the side facing the housing 10; and both the first cover plate 31 and the second cover plate 32 have a third contact surface 33 on the side facing away from the housing 10, which is in contact with the external cooling zone.

[0041] The first bonding surface 311 and the second bonding surface 321 are respectively bonded to the corresponding heating area 21, so that the heat of the heating area 21 is transferred to the third bonding surface 33 via the first bonding surface 311 and to the third bonding surface 33 via the second bonding surface 321.

[0042] Specifically, the first contact surface 311 and the second contact surface 321 ensure that the first cover plate 31 and the second cover plate 32 are in close contact with the heating area 21 in the housing 10, thereby achieving effective heat conduction.

[0043] Furthermore, the first mating surface 311 and the second mating surface 321 are respectively mated to the corresponding heat-generating areas 21, ensuring that the heat generated by the combiner unit 20 during operation can be directly transferred to the cover plate, thereby preventing heat concentration in the heat-generating areas 21 and avoiding overheating of the equipment. At the same time, the sealing between the cover plate and the housing 10 is enhanced, further improving heat dissipation performance.

[0044] Furthermore, the third bonding surface 33 further promotes heat dissipation through contact with the external cooling zone. The third bonding surface 33 can effectively and rapidly release the heat conducted by the first bonding surface 311 and the second bonding surface 321 to the external cooling zone, thereby improving the heat dissipation capacity of the equipment and ensuring its normal operation under high power and high temperature conditions.

[0045] In one specific embodiment, both the first cover plate 31 and the second cover plate 32 are made of aluminum alloy.

[0046] Specifically, aluminum alloy was chosen as the material primarily because of its excellent thermal conductivity, light weight, and high strength. The use of aluminum alloy not only helps improve the heat dissipation capacity of the equipment but also reduces its overall weight, thereby enhancing its performance. This ensures that the heat generated in the heating zone 21 is rapidly conducted to the cover plate through the first and second mating surfaces 311 and 321, preventing heat accumulation inside the combiner, and is quickly dissipated to the external cooling zone through the third mating surface 33 of the cover plate.

[0047] Furthermore, aluminum alloy materials possess high strength and corrosion resistance, enabling them to maintain stable performance in high-temperature, high-power operating environments without deforming or failing due to prolonged use. The use of aluminum alloy for the first cover plate 31 and the second cover plate 32 not only ensures excellent thermal management but also effectively increases the equipment's lifespan, reducing maintenance and replacement costs caused by material aging or failure.

[0048] In one specific embodiment, both the first fastener 41 and the second fastener 42 are arranged along the array of the combiner unit 20.

[0049] Specifically, the combiner units 20 are arranged in a certain array within the housing 10, typically in a row-column layout, to maximize space utilization and ensure appropriate heat dissipation distance between each combiner unit 20. The arrangement of the first fastener 41 and the second fastener 42 is consistent with the direction of the combiner unit 20 array, ensuring that each combiner unit 20 can be securely connected to the cover plate assembly 30 via fasteners.

[0050] Furthermore, the array arrangement of the first fastener 41 and the second fastener 42 helps to distribute the pressure applied to the cover plate, thereby making heat conduction more uniform and efficient. This arrangement can also reduce local stress concentration and prevent cover plate deformation or loosening caused by uneven stress, thereby improving the stability and heat dissipation performance of the equipment.

[0051] In one specific embodiment, the combiner further includes a positioning component 50. The positioning component 50 includes a first positioning member 51 and a second positioning member 52, the first positioning member 51 passing through the first cover plate 31, and the second positioning member 52 passing through the second cover plate 32.

[0052] Specifically, the first cover plate 31 and the second cover plate 32 can mate with the positioning part 12 in the housing 10 during installation, ensuring that the installation position of the cover plates does not shift. This ensures a more precise fit between the cover plates and the housing 10, avoiding problems such as uneven heat conduction or poor heat dissipation caused by inaccurate installation.

[0053] Furthermore, the first positioning member 51 allows it to pass through the first cover plate 31 through a through hole or slot and engage with the housing 10. Similarly, the second positioning member 52 passes through the second cover plate 32 through a hole or slot and engages with the positioning part 12 on the housing 10.

[0054] The design of the positioning components makes the installation of the cover plate and the housing 10 simpler and more efficient. Since the first positioning component 51 and the second positioning component 52 are respectively inserted into the first cover plate 31 and the second cover plate 32, the assembly personnel can ensure that the cover plate is correctly installed through simple docking and fixing operations, reducing errors in the installation process and improving production efficiency.

[0055] Furthermore, the way the first positioning member 51 and the second positioning member 52 are inserted creates a stable connection frame between the cover plate and the housing 10. The first cover plate 31 and the second cover plate 32 can respectively contact the heat-generating area 21 inside the housing 10, thereby ensuring that heat can be efficiently conducted from the heat-generating area 21 to the surface of the cover plate and further dissipated to the external cooling area. This structure not only optimizes the heat dissipation effect but also enhances the overall stability and service life of the equipment.

[0056] In one specific embodiment, the housing 10 further includes a positioning part 12. The positioning part 12 has a first positioning post 121 and a second positioning post 122, the first positioning post 121 being disposed on one side of the housing 10, and the second positioning post 122 being disposed on the side of the housing 10 opposite to the first positioning post 121.

[0057] The first positioning member 51 extends into the first positioning post 121, and the second positioning member 52 extends into the second positioning post 122.

[0058] In one specific embodiment, both the first positioning post 121 and the second positioning post 122 are provided with positioning holes 123 for accommodating positioning components.

[0059] Specifically, the positioning posts further ensure the connection between the cover plate and the housing 10, providing additional support and stability.

[0060] Furthermore, the first positioning member 51 extends into the first positioning post 121, and the second positioning member 52 extends into the second positioning post 122. This allows the first positioning member 51 and the second positioning member 52 to engage with the positioning posts on the housing 10. In this way, the positioning members can ensure the connection between the cover plate and the housing 10 and prevent the cover plate from shifting due to external forces or vibrations during installation.

[0061] Furthermore, both the first positioning post 121 and the second positioning post 122 are provided with positioning holes 123 for accommodating positioning components. The positioning holes 123 ensure that the first positioning component 51 and the second positioning component 52 can smoothly enter and be fixed in the positioning post, thereby enhancing the positioning between the cover plate and the housing 10.

[0062] Furthermore, the presence of the positioning hole 123 not only enhances the accuracy of positioning during installation, but also ensures the stability of the positioning part 12 during long-term use, avoiding positioning failure caused by vibration or other external factors.

[0063] In one specific embodiment, the first positioning member 51 further includes a pad 511, which is sleeved on the outside of the first positioning member 51 and located on the side of the first cover plate 31 facing away from the housing 10.

[0064] In one specific embodiment, the gasket 511 is a nut.

[0065] Specifically, both the first positioning member 51 and the second positioning member 52 are screws that cooperate with the nut, ensuring that the first positioning member 51 can be fixedly connected to the first cover plate 31 and the second positioning member 52 can be fixedly connected to the second cover plate 32.

[0066] In use, the first positioning member 51 of the first cover plate 31 is positioned with the positioning part 12 inside the housing 10. The positioning part 12 inside the housing 10 is provided with a positioning hole 123 suitable for accommodating the first positioning member 51. The first positioning member 51 is accurately inserted into the positioning hole 123 of the positioning part 12 by screws, realizing the docking of the first cover plate 31 and the housing 10. The second positioning member 52 of the second cover plate 32 is also positioned by screws into the positioning part 12 of the housing 10, ensuring that the second cover plate 32 is also firmly fixed to the housing 10.

[0067] Therefore, the combiner 100 of the repeater provided above improves the system integration by setting multiple combiner units 20 on both sides of the housing 10; and forms an effective heat conduction path by having the first cover plate 31 and the second cover plate 32 in close contact with the heat-generating area 21 of each combiner unit 20. This double-sided cover plate structure ensures that heat is evenly distributed in both directions, effectively reducing energy loss caused by heat concentration, thereby optimizing thermal management. By accelerating the conduction of heat from the heat-generating area 21 to the cover plate, heat accumulation inside is avoided, reducing equipment losses and performance degradation caused by overheating.

[0068] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
