Description

Technical Field

[0001] The present invention relates to the technical field of radiators, and in particular to a radiator for communication equipment and a packaging method thereof. Background Art

[0002] With the rapid development of modern communication technologies such as 5G communications, data centers, and high-speed network equipment, communications equipment is rapidly evolving toward high integration, high frequency, high speed, and high power density. The power consumption and heat generation of core functional units (such as CPUs, GPUs, ASICs, FPGAs, and power amplifiers) and high-power RF modules are rapidly increasing. If the resulting enormous heat cannot be dissipated promptly and efficiently, the chip temperature will rise rapidly, seriously affecting the stability, reliability, and service life of communications equipment.

[0003] In the existing technology, the radiator is the core component of the thermal management system that directly contacts the heat-generating device and transfers heat to the external environment. Its performance is crucial. Traditional radiators generally adopt an aluminum extrusion structure or an aluminum plate welded fin structure, and their heat dissipation relies on natural convection or air cooling. However, due to the limitations of the heat dissipation structure and heat dissipation method of traditional radiators, their heat dissipation efficiency is low. For high power density application scenarios, traditional radiators are difficult to meet the requirements of fast heat conduction and efficient heat dissipation. Heat easily accumulates in the core heating area, thereby affecting the operating performance of communication equipment. Summary of the Invention

[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] Example 1: The embodiment of the present invention provides a heat sink for communication equipment, such as Figures 1 to 18 As shown, the heat sink 10 includes a first mounting member 20 and a second mounting member 30. The heat sink 10 includes a heat sink body 11. The heat sink body 11 is provided with first heat sink fins 12 and second heat sink fins 13 arranged along a first direction. The heat sink body 11 is also provided with a plurality of third heat sink fins 14 located between the first heat sink fins 12 and the second heat sink fins 13 and distributed at intervals. A main channel 111 is provided within the heat dissipation body 11 for facilitating the circulation of the coolant. A liquid inlet pipe 40 and a liquid outlet pipe 50 are mounted on the same side of the heat dissipation body 11. One of the third heat dissipation fins 14 passes through the second mounting member 30. A first mounting slot 112 is defined within the heat dissipation body 11, adjacent to the liquid inlet pipe 40 and arranged along the second direction. The first mounting member 20 passes through the first mounting slot 112. The first direction is perpendicular to the second direction. The gaps between the first heat sink fin 12, the second heat sink fin 13, and the plurality of third heat sink fins 14 form a heat dissipation channel. The first mounting member 20 and the second mounting member 30 are both used to securely mount the heat sink 10. In this embodiment, the liquid inlet pipe 40 and the liquid outlet pipe 50 are both connected to the circulation pump pipeline. The circulation pump is a well-known structure in the art and will not be described in detail here. The circulation pump drives the coolant to circulate within the radiator.

[0024] It should be noted that the present invention provides a radiator for communication equipment. By providing a plurality of third radiating fins 14 spaced apart between the first radiating fins 12 and the second radiating fins 13, the radiator can effectively increase the heat dissipation area within a limited space, thereby improving the heat dissipation efficiency of the heat sink 10. At the same time, the gaps between the first radiating fins 12, the second radiating fins 13 and the plurality of third radiating fins 14 form an orderly heat dissipation channel, which is conducive to the convection flow of air or cooling medium, further enhancing the heat dissipation performance. By providing a main channel 111 within the heat dissipation body 11, the coolant can be guided to circulate within the heat dissipation body 11, and rapid heat conduction can be achieved by means of the thermal conductivity of the coolant, thereby significantly improving the overall heat exchange capacity of the heat sink 10. Since the liquid inlet pipe 40 and the liquid outlet pipe 50 are located on the same side of the heat dissipation body 11, the layout of the coolant pipeline is simplified, which is convenient for installation and maintenance, and meets the requirements of the compact installation space of the actual equipment. The heat sink 10 is fixedly mounted using the first mounting member 20 and the second mounting member 30, ensuring a tight fit between the heat sink and the mounting structure. This not only enhances structural strength but also facilitates the transfer of heat from the heat sink 10 to the mounting member, thereby improving the overall heat dissipation efficiency of the system. Therefore, the present invention solves the technical problem of low heat dissipation efficiency of heat sinks in the prior art.

[0025] like Figures 1 to 8 As shown, a first flow channel 121 is defined in the first heat dissipation fin 12, and a second flow channel 131 communicating with the first flow channel 121 is defined in the second heat dissipation fin 13; a first opening 113 and a second opening 114 are defined in the heat dissipation body 11, the first opening 113 being communicated with the first mounting groove 112 and the main flow channel 111, respectively, and the second opening 114 being communicated with the first mounting groove 112 and the main flow channel 111, respectively; The first mounting member 20 is provided with a first connecting hole 211 and a second connecting hole 212. The first connecting hole 211 is used to be connected to the first opening 113 and the liquid inlet 1211 of the first flow channel 121 respectively. The second connecting hole 212 is used to be connected to the second opening 114 and the liquid outlet of the second flow channel 131 respectively.

[0026] In this embodiment, by providing the first flow channel 121 and the second flow channel 131 which are interconnected, since the first connecting hole 211 is respectively connected to the first opening 113 and the liquid inlet 1211 of the first flow channel 121, the first flow channel 121 is connected to the main flow channel 111; since the second connecting hole 212 is respectively connected to the second opening 114 and the liquid outlet of the second flow channel 131, the second flow channel 131 is connected to the main flow channel 111, and then the first flow channel 121, the second flow channel 131 and the main flow channel 111 form a circulation loop, which increases the contact area between the coolant and the heat sink 10, thereby significantly improving the heat exchange efficiency and achieving faster and more uniform heat conduction and release.

[0027] like Figures 1 to 18 As shown, each third heat dissipation fin 14 is provided with a third flow channel 141, and a fourth flow channel 115 is provided in the middle of the heat dissipation body 11. The fourth flow channel 115 is used to sequentially connect the first flow channel 121, a plurality of third flow channels 141 and the second flow channel 131; The first flow channel 121, the second flow channel 131, and the third flow channel 141 are all arranged in a wavy shape. The third flow channel 141 is closed at both ends along the second direction. The height of the third heat sink 14 in the third direction is lower than the height of the first heat sink 12 and the second heat sink 13 in the third direction. In this embodiment, the heat sink 10 is provided with a vent 16 connected to the second flow channel 131. A vent membrane 90 is fixedly mounted at the vent 16. The provision of the vent membrane 90 facilitates balancing the air pressure in the second flow channel 131 when the main flow channel 111 is disconnected from the second flow channel 131, preventing the generation of negative pressure. When the main flow channel 111 is connected to the second flow channel 131, the air in the second flow channel 131 is smoothly discharged to the outside through the vent membrane 90.

[0028] In this embodiment, the fourth flow channel 115 is used to sequentially connect the first flow channel 121, several third flow channels 141, and the second flow channel 131, thereby realizing a partitioned and continuous flow path layout of the coolant between the heat dissipation body 11 and various heat dissipation fins, further improving the overall heat exchange efficiency of the cooling system. After the coolant enters through the first flow channel 121, it is distributed to each third flow channel 141 through the fourth flow channel 115 in turn, and then converges to the second flow channel 131, thereby realizing a multi-path heat dissipation circuit design, which can effectively reduce thermal resistance and achieve uniform heat dissipation. Since the first flow channel 121, the second flow channel 131, and the third flow channel 141 are all arranged in a wavy structure, the flow path of the coolant in the channel is significantly extended, which helps to increase the heat exchange time and contact area, improve the cooling effect, and avoid local overheating. In addition, the wavy flow channel also has a certain turbulent effect, which is conducive to destroying the coolant boundary layer and enhancing the convective heat transfer capacity, thereby further improving the heat dissipation efficiency.

[0029] It should be noted that because both ends of the third flow channel 141 are closed along the second direction, the coolant flow direction within each third heat sink fin 14 is controlled and the path is clear. This facilitates uniform coolant inflow and outflow and precise regulation, avoids flow short-circuits or dead zones, and ensures the stability and efficiency of the heat exchange process. Each third heat sink fin 14 is lower in the third direction than the first and second heat sink fins 12, 13, achieving a highly layered arrangement at the structural level. This helps optimize the flow path of air or cooling medium within the radiator, allowing hot air to flow effectively between different height levels and improving the efficiency of natural convection or forced air cooling.

[0030] like Figures 15 to 17 As shown, a first limiting surface 1121 and a second limiting surface 1122 are defined in the first mounting groove 112. The first mounting member 20 includes a mounting body 21 and a protruding portion 22. The protruding portion 22 is configured to abut against the side wall of the heat dissipation body 11, so that the first communication hole 211 and the first opening 113 are located on the same straight line along the first direction, and the second communication hole 212 and the second opening 114 are located on the same straight line along the first direction. When the mounting body 21 abuts against the first limiting surface 1121, the first connecting hole 211 is not connected to the first opening 113, and the second connecting hole 212 is not connected to the second opening 114; when the mounting body 21 abuts against the second limiting surface 1122, the first connecting hole 211 is connected to the first opening 113, and the second connecting hole 212 is connected to the second opening 114.

[0031] It should be noted that the provision of the protrusion 22 enables precise alignment of the first connecting hole 211 with the first opening 113, and of the second connecting hole 212 with the second opening 114 in the first direction, significantly improving the accuracy and controllability of the coolant path connection. When the mounting body 21 abuts the first limiting surface 1121, neither the first connecting hole 211 nor the second connecting hole 212 connects with the corresponding openings, thereby physically disconnecting the coolant circuit. When the mounting body 21 abuts the second limiting surface 1122, the first connecting hole 211 connects with the first opening 113, and the second connecting hole 212 connects with the second opening 114, respectively, forming a complete coolant circulation path. This allows the radiator to have two operating states, allowing users to adjust the radiator's operating state accordingly based on the actual application scenario.

[0032] like Figures 1 to 18 As shown, a second mounting groove 116 is provided at the liquid inlet 1211 of the first flow channel 121 and is communicated with the first mounting groove 112 , and a third mounting groove 117 is provided at the liquid outlet 1311 of the second flow channel 131 and is communicated with the first mounting groove 112 ; A first elastic piece 60 abutting the mounting body 21 is fixedly installed in the second mounting groove 116 , and a second elastic piece 70 abutting the mounting body 21 is fixedly installed in the third mounting groove 117 . The first elastic piece 60 is provided with at least one first through hole 611 , and the second elastic piece 70 is provided with at least one second through hole 711 .

[0033] Specifically, when the mounting body 21 is inserted into the first mounting groove 112, the mounting body 21 squeezes the first elastic piece 60 and the second elastic piece 70. When the mounting body 21 abuts the first limiting surface 1121, the first communicating hole 211 is disconnected from the first opening 113, and the second communicating hole 212 is disconnected from the second opening 114. The first flow channel 121 and the second flow channel 131 are respectively disconnected from the main flow channel 111. At this time, the first elastic piece 60 and the second elastic piece 70 can compress the mounting body 21, so that the mounting body 21 fits more closely with the first opening 113 and the second opening 114, thereby preventing the coolant in the main flow channel 111 from leaking. In addition, when the mounting body 21 abuts against the second limiting surface 1122, the first connecting hole 211 is connected to the first opening 113, and the second connecting hole 212 is connected to the second opening 114, so that the main channel 111, the first channel 121, the second channel 131, the third channel 141 and the fourth channel 115 form a circulation loop of the coolant, thereby enhancing the heat dissipation efficiency of the heat sink 10; through the setting of the first through hole 611 and the second through hole 711, the coolant is facilitated to pass through the first spring clip 60 and the second spring clip 70, thereby ensuring smooth communication of the fluid while providing an effective sealing effect to prevent leakage of the coolant.

[0034] like Figures 15 to 18 As shown, the first elastic piece 60 includes a first body 61 arranged in a circular shape, a plurality of first through holes 611 are provided on the first body 61, and the aperture of the first through holes 611 gradually decreases in the direction away from the center of the circle. Two first connecting portions 62 are connected to both sides of the first body 61, respectively, and the first connecting portions 62 are fixedly connected to the second mounting groove 116; The second spring piece 70 includes a second body 71 arranged in a circular shape, and a plurality of second through holes 711 are arranged on the second body 71. The aperture of the second through holes 711 gradually decreases in the direction away from the center of the circle. Two second connecting parts 72 are respectively connected to the two sides of the second body 71. The second connecting parts 72 are fixedly connected in the third mounting groove 117.

[0035] It should be noted that since the aperture of the first through hole 611 gradually decreases away from the center, it helps regulate the coolant flow rate and flow distribution, causing the coolant to form a flow state with a gradually diffused flow from the center outward and a decreasing flow rate when passing through the first spring plate 60, thereby improving the contact between the coolant and the inner wall of the first flow channel 121 and the heat exchange effect. Because the first connecting portion 62 is fixedly connected to the second mounting groove 116 and the first connecting portion 62 is fixedly connected to the second mounting groove 116, the first spring plate 60 and the second spring plate 70 are stably installed, and have good vibration and impact resistance during equipment operation, preventing positional displacement caused by external vibration or fluid impact.

[0036] like Figures 1 to 14As shown, the aperture of the main channel 111 is larger than the apertures of the first channel 121, the second channel 131, the third channel 141 and the fourth channel 115. The apertures of the liquid inlet 1211, the first connecting hole 211 and the first opening 113 of the first channel 121 are the same, and the apertures of the liquid outlet 1311, the second connecting hole 212 and the second opening 114 of the second channel 131 are the same.

[0037] It should be noted that the main channel 111 adopts a larger aperture design, which significantly reduces the fluid resistance in the main circulation path, allowing the coolant to flow quickly with low pressure loss, meeting the needs of simultaneous liquid supply from multiple branch channels, and effectively improving the overall heat exchange capacity and circulation efficiency of the radiator. Because the apertures of the liquid inlet 1211, the first connecting hole 211, and the first opening 113 of the first channel 121 are the same, and the apertures of the liquid outlet 1311, the second connecting hole 212, and the second opening 114 of the second channel 131 are the same, local throttling effects or turbulence caused by aperture differences are avoided, ensuring stable flow rate and pressure balance of the coolant during inflow and outflow.

[0038] like Figures 1 to 14 As shown, one end of the liquid inlet pipe 40 inserted into the main channel 111 abuts against the first opening 113, and a third communication hole 41 is formed on the liquid inlet pipe 40 and located in the main channel 111. One end of the liquid outlet pipe 50 inserted into the main channel 111 abuts against the second opening 114, and a fourth communication hole 51 is formed on the liquid outlet pipe 50 and located in the main channel 111. A first protrusion 42 is formed on the outer wall of the liquid inlet pipe 40, and a second protrusion 52 is formed on the outer wall of the liquid outlet pipe 50. A ridge 15 is formed on the heat dissipation body 11 for abutting against the first protrusion 42 and the second protrusion 52, respectively. When the first protrusion 42 and the second protrusion 52 are respectively in contact with the ridge 15, the third communication hole 41 is not in contact with the first opening 113, and the fourth communication hole 51 is not in contact with the second opening 114. The third communication hole 41 is used to connect the main channel 111 with the first opening 113, and the fourth communication hole 51 is used to connect the main channel 111 with the second opening 114. In the specific implementation, at least two first sealing rings 81 are sleeved on the liquid inlet pipe 40 and abut against the inner wall of the main channel 111, and at least two second sealing rings 82 are sleeved on the liquid outlet pipe 50 and abut against the inner wall of the main channel 111.

[0039] It should be noted that when the first protrusion 42 and the second protrusion 52 are respectively in contact with the ridge 15 on the heat dissipation body 11, the third connecting hole 41 and the fourth connecting hole 51 are not connected to the first opening 113 and the second opening 114. This design ensures that the coolant flow path is safely cut off when the coolant has not reached the fully installed position, avoiding liquid leakage or misflow, and improving the sealing and safety of the entire heat dissipation system. When installed in place, the third connecting hole 41 is connected to the first opening 113, and the fourth connecting hole 51 is connected to the second opening 114, forming an effective coolant flow path, ensuring that the coolant flows in the predetermined direction. This precise fluid switching design can efficiently manage the flow of the coolant and reduce flow blockage or unevenness caused by assembly deviation. By rotating the liquid inlet pipe 40 and the liquid outlet pipe 50 respectively, the coolant flow path can be switched without installing additional control valves and pipelines, reducing the complexity of the structure and making the structure more compact.

[0040] like Figures 1 to 18 As shown, the heat dissipation body 11 is provided with a first slot 118 communicating with the first limiting surface 1121 and a second slot 119 communicating with the second limiting surface 1122 ; The mounting body 21 is provided with a first plug-in portion 23 that is plugged into the first slot 118 and a second plug-in portion 24 that is plugged into the second slot 119. The mounting body 21, the protrusion 22, the first plug-in portion 23 and the second plug-in portion 24 are all integrally formed structures; the two parts of the mounting body 21 extending out of the first mounting slot 112 are of unequal lengths.

[0041] It should be noted that by plugging the first plug portion 23 into the first slot 118 and the second plug portion 24 into the second slot 119, the mounting body 21 can be positioned in two corresponding operating states. This prevents displacement of the first mounting member 20 due to external vibration during radiator operation, ensuring smooth connectivity of the coolant circuit. The unequal lengths of the two portions of the mounting body 21 extending from the first mounting slot 112 enhance the vibration resistance of the first mounting member 20.

[0042] Specifically, such as Figures 1 to 10 As shown, the second mounting member 30 includes a bent mounting portion 31 with a clamping portion 32 at each end. One of the clamping portions 32 is provided with a toggle portion 33. The mounting portion 31, clamping portion 32, and toggle portion 33 are integrally formed. In this embodiment, the third heat sink fin 14 passes through the mounting portion 31, where the mounting portion 31 contacts the heat sink body 11. The clamping portions 32 at each end of the mounting portion 31 are secured, thereby securing the heat sink 10 in place. The provision of the toggle portion 33 facilitates removal of the second mounting member 30.

[0043] Working principle: When the radiator is in the first working state, the first plug-in portion 23 is inserted into the first slot 118, the mounting body 21 contacts the first limiting surface 1121, the first communication hole 211 of the mounting body 21 is not connected to the first opening 113, the second communication hole 212 of the mounting body 21 is not connected to the second opening 114, the third communication hole 41 of the liquid inlet pipe 40 can be connected to or not connected to the first opening 113, and the fourth communication hole 51 of the liquid outlet pipe 50 can be connected to or not connected to the second opening 114; By installing the first mounting member 20 and the second mounting member 30, the heat sink 10 is tightly installed on the communication equipment, thereby effectively dissipating heat from the communication equipment; a first heat sink fin 12, a second heat sink fin 13 and a third heat sink fin 14 are provided on the heat sink body 11, which increases or decreases the heat dissipation area of ​​the heat sink 10 and improves the heat dissipation efficiency of the heat sink 10; in addition, the coolant circulates along the main channel 111 under the pumping action of the external circulation pump, further improving the heat dissipation efficiency of the heat sink 10 and solving the technical problem of low heat dissipation efficiency of traditional radiators.

[0044] The first mounting member 20 is used to seal the first opening 113 and the second opening 114 to prevent leakage of the coolant in the main channel 111, so that the first mounting member 20 has the dual functions of mounting and sealing; the first spring piece 60 and the second spring piece 70 are respectively abutted against the mounting body 21, further tightening the first mounting member 20, effectively offsetting the water pressure in the main channel 111, and preventing leakage of the coolant in the main channel 111.

[0045] When the radiator is in the second working state, the second plug-in portion 24 is inserted into the second slot 119, the mounting body 21 contacts the second limit surface 1122, the first connecting hole 211 of the mounting body 21 is connected to the first opening 113, the second connecting hole 212 of the mounting body 21 is connected to the second opening 114, the third connecting hole 41 of the liquid inlet pipe 40 is connected to the first opening 113, and the fourth connecting hole 51 of the liquid outlet pipe 50 is connected to the second opening 114; thereby, the main channel 111, the first flow channel 121, the fourth flow channel 115, the third flow channel 141 and the second flow channel 131 are connected, thereby increasing the circulation flow path of the coolant and further improving the heat dissipation efficiency of the heat sink 10.

[0046] Since the first flow channel 121, the second flow channel 131 and the third flow channel 141 are all arranged in a wavy structure, the flow path of the coolant in the channel is significantly extended, which helps to increase the heat exchange time and contact area. The wavy flow channel also has a certain turbulent effect, which is beneficial to destroy the coolant boundary layer and enhance the convective heat transfer capacity, thereby further improving the heat dissipation efficiency.

[0047] At least one first through-hole 611 is provided in the first spring piece 60, and at least one second through-hole 711 is provided in the second spring piece 70, facilitating the flow of coolant within the channel, thereby achieving a circulation loop. The first and second spring pieces 60 and 70 press against the mounting body 21, preventing the coolant from escaping through the gap between the mounting body 21 and the heat sink body 11. Since the aperture of the first through-hole 611 gradually decreases away from the center, this helps regulate the coolant flow rate and flow distribution. As the coolant passes through the first spring piece 60, it forms a flow state that gradually diffuses outward from the center with decreasing flow rate, thereby enhancing the contact between the coolant and the inner wall of the first flow channel 121 and the heat exchange effect.

[0048] In addition, the aperture of the main channel 111 is larger than the apertures of the first channel 121, the second channel 131, the third channel 141 and the fourth channel 115. The first through hole 611 of the first spring 60 also has a filtering function to prevent impurities or foreign matter in the coolant from entering the first channel 121, ensuring that the coolant flows smoothly in the circulation loop, and avoiding the technical problem of the first channel 121 being blocked by impurities or foreign matter in the coolant.

[0049] Example 2: The embodiment of the present invention provides a packaging method for a heat sink for communication equipment, such as Figure 19 As shown, the heat sink for communication equipment used for packaging as in the first embodiment includes: Step S1: forming a heat sink 10, a first mounting member 20, a second mounting member 30, a liquid inlet pipe 40, and a liquid outlet pipe 50, respectively. The heat sink 10 includes a heat sink body 11, a first heat sink fin 12, a second heat sink fin 13, and a third heat sink fin 14. Step S2, opening a main channel 111 and a first mounting groove 112 in the heat dissipation body 11; Step S3: embed the liquid inlet pipe 40 and the liquid outlet pipe 50 in the main channel 111 respectively, pass the first mounting member 20 through the first mounting groove 112, and pass the third heat dissipating fin 14 through the second mounting member 30; Step S4, sequentially locking the first mounting member 20 and the second mounting member 30 on the communication device; Step S5 , connecting the liquid inlet pipe 40 and the liquid outlet pipe 50 to the circulation pump pipeline respectively, so that the coolant circulates in the main channel 111 .

[0050] It should be noted that by locking the first mounting member 20 and the second mounting member 30 on the communication equipment in sequence, the various components of the radiator are ensured to be firmly positioned in the equipment. The locking structure ensures that the connection between the radiator and the communication equipment is firm and reliable, and prevents loosening due to vibration or external force during use, thereby ensuring the stability and effectiveness of the cooling system in long-term use. The liquid inlet pipe 40 and the liquid outlet pipe 50 are respectively connected to the circulation pump, so that the coolant circulates in the main channel 111, achieving efficient heat conduction and heat exchange. The continuous flow of coolant can fully remove the heat from various parts of the radiator, ensuring that the communication equipment can maintain a stable temperature when working under high load, and avoiding performance degradation or equipment failure caused by overheating.
