Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication equipment technology, and more specifically, to a fiber optic repeater with good heat dissipation. Background Technology
[0002] A fiber optic repeater is a wireless signal relay device that transmits base station signals to coverage blind spots via optical fiber. It consists of a near-end unit and a far-end unit: the near-end unit couples the base station signal and converts it into an optical signal, which is then transmitted to the far-end unit via optical fiber; the far-end unit converts the optical signal back into a radio frequency signal, amplifies it, and retransmits it through an antenna, effectively extending network coverage. It features high isolation, low noise, and strong anti-interference capabilities, solving weak signal coverage problems in complex scenarios such as subways, tunnels, and mountainous areas, while avoiding the self-oscillation risk of traditional repeaters. It is a preferred low-cost solution for expanding network capacity.
[0003] Patent CN217335581U discloses a digital fiber optic repeater remote unit with good heat dissipation, including a base box and a top cover, which are fixedly connected by bolts. A connector is fixedly connected to the front of the base box, and the remote unit body is fixedly connected to the inner bottom wall of the base box. Fins are fixedly connected to the lower surface of the base box and the upper surface of the top cover. Heat dissipation vents are opened on both sides of the base box, and a water-cooling assembly is fixedly connected to the back of the base box. This utility model collects rainwater in a water collection tank and diverts it to two pressure tanks through a connecting channel. The piston moves towards the base box under the pressure of the rainwater, overcoming the spring force, until the overflow hole is exposed. The rainwater enters the cooling pipe through the overflow hole and exchanges heat with the remote unit body through the heat-conducting fins, thus solving the problem of poor heat dissipation affecting the normal operation of the remote unit.
[0004] When in use, the structure absorbs heat by contacting the cooling pipe with the main body. However, the heat-conducting fins and cooling pipes are not tightly attached to the main body, resulting in gaps or a small contact area. This makes it difficult for heat to be transferred to the cooling pipes, causing insufficient heat dissipation at the contact surface and affecting the heat dissipation effect. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fiber optic repeater with good heat dissipation to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a fiber optic repeater with good heat dissipation, comprising a base plate, a heat dissipation assembly, and a repeater, wherein the heat dissipation assembly is fixedly mounted on the base plate, and the repeater is mounted inside the heat dissipation assembly;
[0007] The heat dissipation assembly includes multiple lead screws, two heat conduction mechanisms, connecting hoses, and a recycling mechanism. The multiple lead screws are fixedly mounted on the base plate, the two heat conduction mechanisms are sleeved on the lead screws, the multiple connecting hoses are fixedly connected between the two heat conduction mechanisms, and the repeater station is located between the two heat conduction mechanisms. The recycling mechanism is fixedly mounted on the top of the lead screws.
[0008] The heat conduction mechanism includes multiple threaded sleeves, a heat conduction frame, multiple limiting rings, and a silicone pad. The multiple threaded sleeves are sleeved on the lead screw. The heat conduction frame has mounting holes, and the threaded sleeves are connected to the mounting holes by bearings. The limiting rings are threaded on the lead screw and are located on both sides of the heat conduction frame. The silicone pad is fixedly installed at the lower end of the heat conduction frame.
[0009] Preferably, the recycling mechanism includes a first mounting plate, a second mounting plate, fins, two enclosed plates, a protective cover, and a shielding frame. One end of the first mounting plate is fixedly mounted on a lead screw on one side, and one end of the second mounting plate is fixedly mounted on a lead screw on the other side. The fins are fixedly connected between the first and second mounting plates and are arranged at an angle. The two enclosed plates are fixedly disposed at both ends of the fins. One end of the protective cover is fixedly disposed on the first mounting plate, and the other end of the protective cover is fixedly disposed on the second mounting plate. The shielding frame is fixedly disposed between the heat-conducting frame and the fins.
[0010] Preferably, the inner cavities of the heat-conducting frame and the connecting hose are connected, and the heat-conducting frame located on the upper side of the repeater is provided with vent holes evenly, and a water inlet pipe is fixedly installed on the heat-conducting frame located on the upper side of the repeater, and the interior of the water inlet pipe is closed, and a fan is installed on the repeater.
[0011] Preferably, the sealing plate has curved grooves.

[0017] 1. By setting a thermally conductive silicone pad on the thermally conductive frame, compared with the existing technology, it is possible to avoid heat accumulation due to gaps between the thermally conductive frame and the repeater, which would affect the working efficiency of the repeater. While ensuring the contact area between the thermally conductive frame and the repeater, it is also possible to prevent the silicone pad from hindering heat transfer.
[0018] 2. The working fluid that has been liquefied again on the fins is collected by the water storage device and transported to the heat conduction frame on the lower side of the repeater through the guide pipe. Compared with the existing technology, this can prevent the gas from flowing directly into the heat conduction frame on the upper side of the repeater after liquefaction, which would make it difficult for the liquid in the heat conduction frame on the lower side of the repeater to vaporize, resulting in heat accumulation and affecting the heat dissipation effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] As attached Figure 1-5 The fiber optic repeater shown includes a base plate 1, a heat dissipation assembly 2, and a repeater 3. The heat dissipation assembly 2 is fixedly mounted on the base plate 1, and the repeater 3 is disposed inside the heat dissipation assembly 2.
[0027] The heat dissipation assembly 2 includes multiple lead screws 21, two heat conduction mechanisms 22, connecting hoses 23, and a recycling mechanism 24. The multiple lead screws 21 are fixedly installed on the base plate 1, the two heat conduction mechanisms 22 are sleeved on the lead screws 21, the multiple connecting hoses 23 are fixedly connected between the two heat conduction mechanisms 22, and the repeater station 3 is located between the two heat conduction mechanisms 22. The recycling mechanism 24 is fixedly installed on the top of the lead screws 21.
[0028] The heat conduction mechanism 22 includes multiple threaded sleeves 221, a heat conduction frame 222, multiple limiting rings 223, and a silicone pad 224. The multiple threaded sleeves 221 are sleeved on the lead screw 21. The heat conduction frame 222 has mounting holes, and the threaded sleeves 221 are connected to the mounting holes by bearings. The limiting rings 223 are threaded on the lead screw 21 and are located on both sides of the heat conduction frame 222. The silicone pad 224 is fixedly installed at the lower end of the heat conduction frame 222.
[0029] Furthermore, the recycling mechanism 24 includes a first mounting plate 241, a second mounting plate 242, fins 243, two sealing plates 244, a protective cover 245, and a shielding frame 246. One end of the first mounting plate 241 is fixedly mounted on a lead screw 21 on one side, and one end of the second mounting plate 242 is fixedly mounted on a lead screw 21 on the other side. The fins 243 are fixedly connected between the first mounting plate 241 and the second mounting plate 242, and the fins 243 are arranged at an angle. The two sealing plates 244 are fixedly disposed at both ends of the fins 243. One end of the protective cover 245 is fixedly disposed on the first mounting plate 241, and the other end of the protective cover 245 is fixedly disposed on the second mounting plate 242. The shielding frame 246 is fixedly disposed between the heat-conducting frame 222 and the fins 243.
[0030] By setting a shielding frame 246 between the heat-conducting frame 222 and the fins 243, the flow direction of the gas after the working fluid vaporizes can be guided and collected, so that the gas can be liquefied and returned to the heat-conducting frame 222 for operation.
[0031] By arranging the fins 243 at an angle, it is easier to collect liquefied gases.
[0032] Furthermore, the inner cavities of the heat-conducting frame 222 and the connecting hose 23 are connected, and the heat-conducting frame 222 located on the upper side of the repeater 3 is provided with vent holes evenly, and a water inlet pipe 247 is fixedly installed on the heat-conducting frame 222 located on the upper side of the repeater 3, and the interior of the water inlet pipe 247 is closed. A fan 31 is installed on the repeater 3. By installing a fan 31 on the repeater 3, heat accumulation in the repeater 3 can be prevented when the heat dissipation component 2 fails to work.
[0033] Furthermore, the sealing plate 244 is provided with curved grooves. By providing curved grooves on the sealing plate 244, it is possible to prevent the sealing plate 244 from obstructing the fins 243 and affecting the heat dissipation effect.
[0034] Furthermore, one end of the protective cover 245 is provided with multiple ventilation openings 2451, and a protective net 2452 is provided inside the ventilation opening 2451. The other end of the protective cover 245 is provided with a second ventilation opening 2453, and a fan 2454 is fixedly installed in the second ventilation opening 2453. Baffles 2455 are fixedly installed at both ends of the protective cover 245. By setting the fan 2454, the gas inside the protective cover 245 is allowed to circulate, thereby preventing the instability of the fins 243 in operation.
[0035] Furthermore, a water storage component 2461 is fixedly installed inside the shielding frame 246. The water storage component 2461 has an L-shaped structure, and the water storage component 2461 and the shielding frame 246 form a collection chamber. A guide pipe 2462 connects the collection chamber to the heat-conducting frame 222 on the lower side of the repeater 3. By setting the water storage component 2461, the liquefied gas is collected and transported to the heat-conducting frame 222 on the lower side of the repeater 3 through the guide pipe 2462. By transporting the recovered working fluid back to the heat-conducting frame 222 on the lower side of the repeater 3, it is possible to prevent the liquefied gas from flowing directly into the heat-conducting frame 222 on the upper side of the repeater 3, which would cause heat accumulation in the heat-conducting frame 222 on the lower side of the repeater 3.
[0036] Furthermore, the mounting plate 241, mounting plate 242, sealing plate 244, fin 243 and protective cover 245 form a cavity. By forming a cavity with the mounting plate 241, mounting plate 242, sealing plate 244, fin 243 and protective cover 245, air circulation can be prevented from causing the working fluid to vaporize and leak.
[0037] Furthermore, the silicone pad 224 is made of thermally conductive silicone material. By setting the silicone pad 224 to thermally conductive silicone material, the heat dissipated by the repeater 3 is guided while ensuring that the heat-conducting frame 222 is in close contact with the repeater 3.
[0038] The working principle of this utility model is as follows: The operator injects working fluid, such as alcohol, into the water inlet pipe 247 until the heat-conducting frame 222 on the upper part of the repeater 3 is full and then stops. The repeater 3 generates heat during operation. The heat emitted by the repeater 3 is guided to the working fluid position through the silicone pad 224. The working fluid evaporates and vaporizes when heated. The vaporized gas passes through the shielding frame 246 and comes to the fin 243 position. The vaporized gas gathers on the fin 243 and liquefies again. After liquefaction, the gas flows through the fin 243 into the collection chamber, and then returns to the heat-conducting frame 222 on the lower side of the repeater 3 through the guide pipe 2462.
[0039] By setting a thermally conductive silicone pad 224 on the thermally conductive frame 222, it is possible to avoid heat accumulation due to gaps between the thermally conductive frame 222 and the repeater 3, which would affect the working efficiency of the repeater 3. While ensuring the contact area between the thermally conductive frame 222 and the repeater 3, it is also possible to prevent the silicone pad 224 from hindering heat transfer.
[0040] The working fluid that has been liquefied again on the fins 243 is collected by the water storage component 2461 and transported to the heat conduction frame 222 on the lower side of the repeater 3 through the guide pipe 2462. This prevents the gas from flowing directly into the heat conduction frame 222 on the upper side of the repeater 3 after liquefaction, which would make it difficult for the liquid in the heat conduction frame 222 on the lower side of the repeater 3 to vaporize, resulting in heat accumulation and affecting the heat dissipation effect.
[0041] It is worth noting that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures, nor will they be described here.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
