Description

Technical Field

[0001] This utility model relates to the field of communication base station power supply technology, and more specifically, to an improved base station power supply. Background Technology

[0002] Currently, mobile communication is developing rapidly and has become an important part of the telecommunications industry. The rapid development of mobile communication is undoubtedly a major highlight and hot topic in today's information society. Currently, the number of mobile communication users worldwide is growing at an astonishing rate of 450 per minute, and my country's total number of mobile users has jumped to first place in the world. Economic growth, social development, and the improvement of people's material and spiritual living standards have placed higher and newer demands on communication. Mobile communication systems, by comprehensively utilizing wired and wireless transmission methods, have solved the problem of communication between people and objects on fixed terminals or other mobile carriers during activities, and have become the fastest-growing and most widely used communication field today. With the rapid growth in the number of mobile communication users, their distribution has expanded from cities to rural areas, from plains to plateaus, remote mountains, and rural areas; at the same time, mobile users have moved from simple voice calls to high-speed data communication, all of which have placed higher demands on the construction of communication networks. The number and performance of base stations are crucial factors affecting the quality of communication networks. Therefore, whether it is providing network coverage that meets specifications, solving the ever-increasing traffic and system capacity bottlenecks, or optimizing the network, improving the performance of base stations are all important means.

[0003] In base stations, the power supply is a crucial component, and its stability and other performance characteristics affect the overall performance of the base station. During operation, the effectiveness of heat dissipation in the power supply directly impacts its stability. This is especially true in remote rural and mountainous areas where base station power supplies operate in harsh environments. Under low voltage and high temperature conditions, they experience heavy loads and generate significant heat. If heat dissipation is inadequate or insufficient, the temperature of internal components will rise rapidly, affecting their performance and potentially damaging them. This impacts the power supply's performance and lifespan, ultimately affecting the overall performance of the base station and increasing maintenance costs.

[0004] Chinese patent document (application number: 201520664646X, application date: 2015.08.30) discloses a natural cooling communication base station power supply system, see [link to patent document]. Figure 1 As shown, Figure 1This is a structural schematic diagram of a natural cooling communication base station power supply system from Chinese patent literature. This natural cooling communication base station power supply system can be used to power outdoor or indoor 3G or 4G communication equipment. It includes a housing assembly 1' and electronic components 2' disposed within the housing assembly 1'. The housing assembly includes a box 11' with an opening and a cover 12' connected to the opening of the box 11'. The box 11' and the cover 12' can be made of metal. Multiple spaced heat dissipation fins 111' are integrally formed on the surface of the box 11' and / or the cover 12', effectively increasing the heat dissipation surface area of ​​the housing assembly 1' and improving the product's heat dissipation effect. The housing 11' has a heat-conducting plate 3' with one side attached to the bottom wall of the housing 11'. The electronic component 2' includes a circuit board 21' and an electronic element 22' connected to one side of the circuit board 21'. The other side of the circuit board 21' is attached to the other side of the heat-conducting plate 3'. The heat generated by the electronic component 2' can be conducted to the housing assembly 1' through the heat-conducting plate 3', and then radiated to the outside by the housing assembly 1', thereby reducing the operating temperature of the electronic component 2'. Moreover, at least one of the electronic elements 22' is provided between the cover 12' and the elastic heat-conducting pad 4'. The two sides of the elastic heat-conducting pad 4' are respectively attached to the inner sides of the electronic element 22' and the cover 12'. The above solution requires the elastic heat-conducting pad 4' to be placed between the electronic element and the cover 12'. Figure 1 As shown, the aforementioned elastic thermal pad 4' is placed between the cover and the electronic component 22', but does not fill the entire housing 11'. When the base station power supply is working, only a few components in some electronic components 22' generate heat, such as transformers and power diodes. However, the transformers and power diodes occupy a small area in the circuit board 21'. Using the above solution results in a waste of material for the elastic thermal pad 4', increasing its cost. At the same time, after the cover 12' closes the housing 11', when the natural cooling communication base station power supply system is moved at will, since the elastic thermal pad 4' does not fill the entire housing 11', it can move within the housing 11', thus preventing the elastic thermal pad 4' from dissipating heat from the heat-generating components. Furthermore, since the cover 12' is directly connected to the housing 11' with screws, without a sealing structure, dust and foreign objects can easily enter 11', covering the electronic component 22', affecting heat dissipation, and causing short circuits and unstable operation of the equipment. Therefore, this is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0019] Compared with the prior art, the improved base station power supply provided by this utility model achieves at least the following beneficial effects:

[0020] The improved base station power supply provided by this utility model includes a housing and electronic components.

[0042] A guide rail assembly 121 is provided in the recess 120 of the box cover. The guide rail assembly 121 includes a guide rail 1211 and a heat-conducting slider 1212 slidably connected to the guide rail 1211. The heat-conducting slider 1212 reciprocates along the length of the guide rail 1211. The guide rail 1211 is long and narrow. The guide rail 1211 extends along the front-back direction X of the box cover 12.

The heat-conducting slider 1212 has a rectangular structure.

[0043] Guide rail grooves 12110 are provided on opposite sides of the Y-guide rail 1211 in the left-right direction of the cover 12. The guide rail grooves 12110 extend along the length direction of the guide rail 1211 and are recessed into the central axis of the guide rail 1211. The heat-conducting slider 1212 is provided with an axial groove 12120 on the side near the guide rail 1211. The axial groove 12120 extends along the length direction of the guide rail slider 1212. A protrusion 121201 matching the guide rail groove 12110 is provided on the side of the axial groove 12120 near the guide rail 1211. The protrusion 121201 slides in the guide rail groove 12110.

[0044] The guide rail 1211 is made of copper alloy, and the thermal slider 1212 is made of materials including silicone, rubber or graphene.

[0045] The side of the heat-conducting slider 1212 away from the guide rail 1211 has a sawtooth structure 12121. After the cover 12 is closed on the box body 11, the heat-conducting slider 1212 contacts the top surface of the transformer 221. Along the direction from the cover 12 to the box body 11, the projected area of ​​the heat-conducting slider 1212 is larger than the projected area of ​​the transformer 221.

[0046] The upper surface of the circuit board 21 and the space between the circuit board 21 and the bottom wall of the housing 11 are filled with potting compound 111.

[0047] Specifically, this embodiment provides an improved base station power supply, which can be a base station power supply with heat dissipation function. The improved base station power supply includes a housing 1 and electronic components 2. The housing 1 can be a rectangular structure, or it can be adjusted according to the actual situation. This embodiment does not make a specific limitation. The housing 1 includes a box body 11 and a box cover 12 that is fastened to the side of the box body 11. The box body 11 includes a bottom plate 112, which is rectangular in shape. The periphery of the bottom plate 112 is connected to an upper side plate 113, a left side plate, a lower side plate, and a right side plate 114. The upper side plate 113, the left side plate (not shown in the figure), the lower side plate (not labeled in the figure), and the right side plate 114 are all rectangular. The upper side plate 113, left side plate, lower side plate, right side plate 114 and bottom plate 112 form a receiving cavity (not marked in the figure), which is a rectangular receiving cavity; the cover 12 can open or close the housing 11, and the electronic components 2 are located inside the housing 11. The cover 12 and the housing 11 are made of aluminum alloy. The aluminum alloy has thermal conductivity and can quickly dissipate the generated heat, effectively preventing the temperature of the housing 1 from getting too high due to long-term operation of the electronic components 2, thereby affecting the stable operation and lifespan of the base station. It can also effectively shield external interference signals, ensure the normal operation of the internal electronic components 2, improve the stability of the improved base station power supply, and is lightweight for easy carrying.

[0048] Both the cover sealing groove 122 and the body sealing groove 110 can be rectangular structures, such as rectangular structures with chamfers. There are two sealing rings 123, and the cover sealing groove 122 and the body sealing groove 110 are matched with two sealing rings 123 respectively. For example, one sealing ring 123 is embedded in the cover sealing groove 122 and the other sealing ring 123 is embedded in the body sealing groove 110. This can not only effectively prevent leakage of the internal medium of the housing 1 and reduce the safety risks of fire, explosion, etc., but also maintain the internal pressure stability of the improved base station power supply, prevent external gas, dust and foreign objects from entering the housing 11, and avoid gas, dust and foreign objects covering the electronic components 22, which is conducive to heat dissipation of the housing 11, thereby ensuring the normal operation of the improved base station power supply. At the same time, it can prevent corrosion and damage, withstand high temperature, and maintain long-term performance stability, thereby improving equipment reliability. In addition, within a certain working pressure and temperature range, the sealing ring 123 can automatically improve the sealing performance. As the pressure increases, the sealing effect is better.

[0049] Electronic component 2 includes circuit board 21 and electronic components 22 connected to one side of circuit board 21. The soldering side of electronic components 22 faces the side of circuit board 21. Circuit board 21 serves as the substrate for electronic components 22, supporting and connecting various electronic components 22, such as resistors, capacitors, transistors, and transformers 221. Electronic components 22 can be fixed on circuit board 21 by soldering, socketing, etc., and connected by wires to form a complete circuit. The wires and conductive patterns on circuit board 21 can transmit signals and power, realize the connection and signal transmission between different electronic components 22. At the same time, arranging electronic components 22, connecting wires and conductive patterns on circuit board 21 can realize the connection and collaborative work between different components, thereby realizing more complex circuit functions while reducing the size and weight of the circuit.

[0050] The circuit board 21 has a rectangular structure. Electronic components 22 include a transformer 221, an inductor 222, and a rectifier diode 223. The transformer 221 is used for voltage transformation and isolation, converting the input voltage into the required operating voltage. Specifically, the transformer 221 not only transforms the AC power supply voltage into the voltage required by the device (achieved through electromagnetic induction), but also provides electrical isolation to prevent high voltage from being conducted to the device during equipment failure, protecting it from damage. In some cases, it can also regulate the voltage to ensure output voltage stability. The transformer 221 generates heat during operation. Because current flows through the transformer 221, resistive losses occur, leading to heat generation. Therefore, the transformer 221 is one of the main heat-generating components. Transformer 221 is a passive component in electronic circuits. It uses the principle of electromagnetic induction to realize the transformation of voltage and current. In the improved base station power supply, the temperature of devices such as transformer 221 is usually controlled at a relatively high level, such as around 120°C. Inductor 222 and capacitor work together to form a filter circuit to suppress high-frequency noise and ensure current stability. Rectifier diode 223 is used to convert AC to DC and is the core component of the power supply rectification process. Electronic component 22 also includes filter capacitor 224, which further smooths the DC current, reduces voltage fluctuations, and improves power quality.

[0051] It should be noted that transformer 221 includes an inductor coil (not shown in the figure) and a magnetic core (not shown in the figure). The inductor coil is usually wound on the magnetic core, and the two are closely integrated to form the core part of transformer 221. The functions of the inductor coil are as follows: storing energy; using the principle of electromagnetic induction to realize the conversion of voltage and current; having the characteristics of passing low frequencies and blocking high frequencies, it can be used in filtering circuits, etc. The functions of the magnetic core are as follows: strengthening the magnetic coupling between the inductor coils, improving the electromagnetic induction efficiency, and serving as a medium for magnetic field conduction to achieve efficient conversion between electrical energy and magnetic energy; depending on the material and characteristics of the magnetic core, the performance of transformer 221 can be further optimized, such as improving the power factor and reducing losses.

[0052] Along the length of the housing 11, the transformer 221 is located between the inductor 222 and the rectifier tube 223. Of course, depending on the actual situation, the transformer 221 can also be located between other different components; this embodiment only illustrates the example of the transformer 221 being located between the inductor 222 and the rectifier tube 223. The filter capacitor 224 is arranged side-by-side with the rectifier tube 223 along the width of the housing 11. Of course, depending on the actual situation, the filter capacitor 224 can also be placed in other positions on the circuit board 21; this embodiment does not specifically limit this.

[0053] It should be noted that electronic component 22 also includes capacitors (not labeled in the figure), DC output terminals 225, and AC input terminals 226. The capacitors not only filter out high-frequency noise in the power supply, ensuring the stability and smoothness of the output voltage, but also store electrical energy in the AC circuit and release it when needed, helping the power system cope with voltage fluctuations. The capacitors allow AC signals to pass through, connecting different circuit parts and enabling signal transmission. The DC output terminals 225 have power distribution and protection functions. Specifically, they distribute power to provide stable DC voltage and current to different load devices, ensuring that each device can operate normally. For protection, when the DC power supply is abnormal, the terminals can generate alarms and implement protective measures to prevent equipment damage. The AC input terminals 226 have functions for introducing external AC power and electrical isolation. Introducing external AC power: This allows mains power or backup power to be introduced into the power system, providing input power to the rectifier and filter unit. Electrical isolation: This ensures the electrical isolation between the power system and the external power grid, protecting the power supply equipment and base station equipment from electrical interference and damage. The positions of the capacitor, DC output terminal 225 and AC input terminal 226 on the circuit board 21 can be adjusted according to the actual situation, and this embodiment does not impose specific limitations.

[0054] A recessed groove 120 is provided on the side of the cover 12 near the enclosure 11. The recessed groove 120 can be designed along the four edges of the cover 12 and is recessed towards the side away from the circuit board 21. The recessed groove 120 is rectangular, which not only increases the bonding strength between the cover 12 and the enclosure 11, preventing the cover 12 from being accidentally opened, thus protecting the internal circuit board 21 and components from external environmental factors such as dust and moisture, improving the safety and stability of the equipment, but also makes it easier to open the cover 12, facilitating daily inspections and emergency handling by staff, improving maintenance efficiency. At the same time, it can distribute the force on the cover 12, enhancing the overall structural strength of the enclosure 11, preventing deformation or damage to the enclosure 11 due to external forces, thereby ensuring the normal operation of the power system. In addition, the guide rail assembly 121 can be set at the recessed groove 120, which is beneficial for heat dissipation of the transformer 221.

[0055] The aforementioned guide rail assembly 121 is disposed within the recess 120 of the box cover. The guide rail assembly 121 includes a guide rail 1211 and a thermally conductive slider 1212. The thermally conductive slider 1212 reciprocates along the length of the guide rail 1211. The guide rail 1211, as a guiding and supporting component, typically has a fixed shape and position. The thermally conductive slider 1212 is designed to cooperate with the guide rail 1211, achieving a sliding connection while also conducting heat. The thermally conductive slider 1212 is directly slidably connected to the guide rail 1211. The thermally conductive pad can be made into a slider shape, i.e., the thermally conductive slider 1212. Specifically, the main steps in making the thermally conductive pad into a slider shape are: raw material preparation and mixing: selecting appropriate thermally conductive silicone material, and mixing with thermally conductive fillers such as metal oxides or nitrides to improve thermal conductivity. Molding is performed using a mold according to the slider's design shape. This process may require heating to solidify the liquid thermally conductive silicone; the solidified thermally conductive silicone undergoes secondary vulcanization to enhance its tensile strength, resilience, hardness, and other properties; after the thermally conductive silicone sheet cools naturally, it is cut according to the specific dimensions of the slider to ensure that the shape and size meet the design requirements; the completed slider-shaped thermal pad is tested for key properties such as thermal conductivity, temperature range, and tensile strength to ensure product quality.

[0056] The guide rail 1211 is elongated, which can be understood as follows: the guide rail 1211 is a straight guide rail, extending along the front-back direction X of the cover 12. After the cover 12 closes the box body 11, the orthographic projection of the transformer 221 in the direction from the box body 11 to the cover 12 coincides with the orthographic projection of the guide rail 1211. That is, the orthographic projection of the transformer 221 in the direction from the box body 11 to the cover 12 is aligned with the orthographic projection of the guide rail 1211. After the cover 12 closes the box body 11, the transformer 221 and the guide rail 1211 are not connected, that is, after the cover 12 closes the box body 11, the transformer 221 and the guide rail 1211 do not contact each other. The heat-conducting slider 1212 has a rectangular structure, such as a cuboid structure.

[0057] Guide rail grooves 12110 are provided on opposite sides of the Y-guide rail 1211 in the left-right direction of the cover 12. The guide rail grooves 12110 extend along the length direction of the guide rail 1211 and are recessed into the central axis of the guide rail 1211. The heat-conducting slider 1212 is provided with an axial groove 12120 on the side near the guide rail 1211. The axial groove 12120 extends along the length direction of the guide rail slider 1212. A protrusion 121201 matching the guide rail groove 12110 is provided on the side of the axial groove 12120 near the guide rail 1211. The protrusion 121201 slides in the guide rail groove 12110.

[0058] The guide rail 1211 is made of copper alloy, and the thermally conductive slider 1212 is made of silicone, rubber, or graphene. The guide rail 1211 has good thermal conductivity, enabling it to quickly transfer the heat generated by the transformer 221 to the cover 12, ensuring the normal operating temperature of the transformer 221. When the thermally conductive slider 1212 is made of silicone, it has resistance to alternating hot and cold temperatures, aging resistance, and electrical insulation properties, as well as good moisture resistance, shock resistance, corona resistance, leakage resistance, and chemical resistance. When the thermally conductive slider 1212 is made of rubber, it can fit into the air gap between the transformer 221 and the guide rail 1211, possessing high compressibility and flexibility, allowing it to tightly conform to the uneven surface of the transformer 221, significantly reducing contact thermal resistance and improving heat transfer efficiency. When the thermally conductive slider 1212 is made of graphene, graphene has high thermal conductivity, and its hexagonal crystal structure allows it to quickly conduct heat in the planar direction.

[0059] The side of the heat-conducting slider 1212 away from the guide rail 1211 has a serrated structure 12121, which more effectively increases the contact area with air, helping to dissipate the heat generated by the transformer 221 more effectively, thereby suppressing the temperature rise of the transformer 221 during operation. After the cover 12 is closed on the housing 11, the heat-conducting slider 1212 is in close contact with the top surface of the transformer 221, which can ensure the stability of the transformer 221 during operation, reduce mechanical stress caused by temperature changes, and help extend the service life of the transformer 221. An effective heat dissipation mechanism is a necessary condition for the transformer 221 to achieve high power density energy transmission. The design of the heat-conducting slider 1212 helps the transformer 221 maintain a stable operating temperature range while maintaining efficient energy transmission.

[0060] Along the direction from the cover 12 to the housing 11, the projected area of ​​the heat-conducting slider 1212 is larger than that of the transformer 221. This can be understood as follows: designing the heat-conducting slider 1212 to be larger than the transformer 221 not only more effectively conducts the heat generated by the transformer 221, increasing the heat dissipation area and rate, thus ensuring the stable operation of the improved base station power supply, but also correspondingly increases the contact area between the heat-conducting slider 1212 and the guide rail 1211. This is beneficial for improving the stability of the internal guide rail assembly 121 of the improved base station power supply. Furthermore, by increasing the projected area of ​​the heat-conducting slider 1212, the heat generated by the transformer 221 can be more evenly distributed on the heat-conducting slider 1212, avoiding localized overheating and extending the service life of the improved base station power supply.

[0061] Since electronic component 22 also includes a power diode and an insulated gate bipolar transistor (IGBT), where the power diode is an electronic device used to convert, transmit, and control electrical energy, and the IGBT is a composite fully controllable voltage-driven power device that combines the advantages of a metal-oxide-semiconductor field-effect transistor (MOSFET) and a bipolar transistor, both the power diode and the IGBT generate heat during operation. Therefore, potting compound 111 is applied to the upper surface of circuit board 21 and between circuit board 21 and the bottom wall of housing 11. Applying potting compound 111 to the upper surface of circuit board 21 forms a protective film, isolating it from moisture, dust, and other environmental factors. Simultaneously, potting compound 111 can also be used to fill the gap between circuit board 21 and the bottom plate 112 in housing 11, providing better protection for circuit board 21 through complete sealing. This potting method not only enhances the mechanical stability of the circuit board 21 and prevents electronic components 22 from loosening or being damaged due to vibration, but also effectively improves the heat dissipation performance of the circuit board 21, ensuring stable operation of the equipment within the optimal temperature range. The aforementioned power diodes and insulated-gate bipolar transistors can be directly pressed onto the base plate 112 of the housing 11 for heat dissipation.

[0062] In specific use, the improved base station power supply described above allows the heat-conducting slider 1212 to slide on the guide rail 1211 according to the position of the transformer 221. The position of the heat-conducting slider 1212 is adjusted so that it slides to the position corresponding to the transformer 221. When the cover 12 closes the box body 11 for sealing, the heat-conducting slider 1212 presses against the transformer 221, making the heat-conducting slider 1212 and the top surface of the transformer 221 fit tightly together. This quickly transfers the heat of the transformer 221 to the heat-conducting slider 1212, the guide rail 1211 and the cover 12 in sequence, effectively dissipating heat from the inductor coil and magnetic core in the transformer 221, which is more conducive to the rapid conduction and dissipation of the heat generated by the transformer 221.

[0063] It should be noted that since the guide rail 1211 is made of copper alloy, while the material of the thermal slider 1212 includes silicone, rubber or graphene, the friction of the thermal slider 1212 when sliding on the guide rail 1211 will be increased. When the thermal slider 1212 slides to the position of the corresponding transformer 221, the thermal slider 1212 will not slide arbitrarily, and the user needs to apply a corresponding force to move the thermal slider 1212.

[0064] Optionally, continue to refer to Figure 8 As shown, Figure 8 This is a cross-sectional schematic diagram of another guide rail assembly provided by this utility model; in this embodiment, a threaded hole (not marked in the figure) is provided on the heat-conducting slider 1212. The threaded hole passes through the heat-conducting slider 1212 in the direction from the heat-conducting slider 1212 to the guide rail 1211. The threaded hole is connected to the axial sliding groove 12120. The threaded hole is located above the protrusion 121201. When the heat-conducting slider 1212 moves to the position of the corresponding transformer 221, the bolt 12122 is tightened to the threaded hole. The top of the bolt abuts against the guide rail 1211, which more effectively prevents the heat-conducting slider 1212 from moving on the guide rail 1211.

[0065] It should be noted that before the heat-conducting slider 1212 moves to the position of the corresponding transformer 221, the bolt 12122 needs to be removed to avoid affecting the sliding of the heat-conducting slider 1212 on the guide rail 1211.

[0066] Compared with the prior art, the improved base station power supply provided in this embodiment achieves at least the following beneficial effects:

[0067] The improved base station power supply provided in this embodiment includes a housing 1 and an electronic component 2. The housing 1 includes a box body 11 and a cover 12 fastened to the side of the box body 11. The electronic component 2 is located inside the box body 11. The cover 12 and the box body 11 are made of aluminum alloy. A cover sealing groove 122 is provided on the periphery of the cover 12 near the box body 11, and a box body sealing groove 110 is provided on the periphery of the box body 11 near the cover 12. The cover sealing groove 122 corresponds to the box body sealing groove 110, and a sealing ring 123 is installed in the box body sealing groove 110 and the cover sealing groove 122. The electronic component 2 includes a circuit board 21 and an electronic component 22 connected to one side of the circuit board 21. The soldering surface faces the circuit board 21. The circuit board 21 has a rectangular structure. The electronic components 22 include a transformer 221, an inductor 222, and a rectifier tube 223. Along the length of the housing 11, the transformer 221 is located between the inductor 222 and the rectifier tube 223. The housing cover 12 has a housing cover groove 120 on the side near the housing 11. The housing cover groove 120 is recessed away from the circuit board 21 and is a rectangular groove. A guide rail assembly 121 is provided in the housing cover groove 120. The guide rail assembly 121 includes a guide rail 1211 and a heat-conducting slider 1212 that is slidably connected to the guide rail 1211. The heat-conducting slider 1212 reciprocates along the length of the guide rail 1211. The guide rail 1211 is elongated and extends along the front-rear direction X of the cover 12. The orthographic projection of the transformer 221 in the direction from the cover 11 to the cover 12 coincides with the orthographic projection of the guide rail 1211. The heat-conducting slider 1212 has a rectangular structure. Guide rail grooves 12110 are provided on opposite sides of the guide rail 1211 along the left-right direction Y of the cover 12. The guide rail grooves 12110 extend along the length of the guide rail 1211 and are recessed towards the central axis of the guide rail 1211. An axial groove 12120 is provided on the side of the heat-conducting slider 1212 near the guide rail 1211. The axial groove 12120 extends along the guide rail slider 1211... Extending along the length direction of 2, the axial slide groove 12120 is provided with a protrusion 121201 matching the guide rail slide groove 12110 on the side near the guide rail 1211. The protrusion 121201 slides in contact with the guide rail slide groove 12110. The guide rail 1211 is made of copper alloy, and the heat-conducting slider 1212 is made of silicone, rubber, or graphene. The side of the heat-conducting slider 1212 away from the guide rail 1211 has a serrated structure 12121. After the cover 12 is closed on the box body 11, the heat-conducting slider 1212 contacts the top surface of the transformer 221. Along the direction from the cover 12 to the box body 11, the projected area of ​​the heat-conducting slider 1212 is larger than the projected area of ​​the transformer 221.The upper surface of circuit board 21 and the space between circuit board 21 and the bottom wall of housing 11 are encapsulated with potting compound 111. Using this method, based on the position and size of transformer 221, the position of heat-conducting slider 1212 can be flexibly adjusted to ensure proper contact with the transformer 221. This also increases the contact area between heat-conducting slider 1212 and transformer 221, more effectively dissipating heat from the transformer 221 and ensuring its normal operation. Simultaneously, it significantly reduces the usable area of ​​heat-conducting slider 1212, saving costs. Furthermore, it effectively prevents leakage of the internal medium of housing 1, reducing safety risks such as fire and explosion. It maintains stable internal pressure of the improved base station power supply, preventing external gases, dust, and foreign objects from entering, thus ensuring the normal operation of the improved base station power supply. It also prevents corrosion and damage, withstands high temperatures, and maintains long-term stable performance, thereby improving equipment reliability.

[0068] In one alternative embodiment, continue to refer to Figure 3 As shown, along the direction from the cover 12 to the housing 11, the difference in the projected area between the heat-conducting slider 1212 and the transformer 221 does not exceed 5mm. Specifically, the difference in the projected area between the heat-conducting slider 1212 and the transformer 221 is 1mm, 2mm, 3mm, 4mm or 5mm. By adopting the above scheme, not only is the contact area between the heat-conducting slider 1212 and the transformer 221 further increased, thereby further improving the heat dissipation effect of the transformer 221, but the use area of ​​the heat-conducting slider 1212 can also be avoided to be too large, which is conducive to saving costs.

[0069] In one alternative embodiment, continue to refer to Figure 3 As shown, the potting compound 111 is made of epoxy resin, silicone rubber, or polyurethane. Epoxy resin has high strength and corrosion resistance, and can maintain the stable performance of circuit board 21 in high temperature and high humidity environments. Silicone rubber has excellent high and low temperature resistance and can be used in the range of -50℃ to +200℃. It has good weather resistance and oxidation resistance. Polyurethane has good water resistance, heat resistance, and cold resistance, and is also resistant to ultraviolet rays and acids and alkalis.

[0070] In one alternative embodiment, combined with Figure 2 and Figure 9 As shown, Figure 9This is a partial enlarged view of the connector; in this embodiment, the box body 11 and the box cover 12 are connected by a connector 13. The connector 13 includes a box body connector 131 and a box cover connector 132. The box body connector 131 is located on the side of the box body 11 near the box cover 12. The box body connector 131 has a U-shaped structure, and the opening of the U-shaped structure is parallel to the length direction of the box body 11. The box cover connector 132 is located on the side of the box cover 12 near the box body 11. The box cover connector 132 includes a head 1321 and a rod 1322 connected to the head 1321. The head 1321 has a circular structure. The head 1321 and the rod 1322 are an integral structure. The rod 1322 is connected to the U-shaped structure, such as by a threaded connection between the rod 1322 and the U-shaped structure.

[0071] The number of the aforementioned connectors 13 can be two. Along the length of the housing 1, the two connectors 13 are located on the upper and lower sides between the box body 11 and the box cover 12, respectively, so as to improve the stability of the housing 1.

[0072] The above solution not only facilitates the quick opening and closing of the box 11 and the cover 12, ensuring the stability of the connection of the shell 1, but also disperses the pressure at the connection point, enhances the overall load-bearing capacity of the box 11, and facilitates maintenance and repair, because the design of the connector 13 makes the disassembly and installation process simpler.

[0073] As can be seen from the above embodiments, the improved base station power supply provided by this utility model achieves at least the following beneficial effects:
