Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to an ultra-small power supply with a honeycomb heat dissipation structure. Background Technology

[0002] Ultra-miniature power supplies are highly integrated and miniaturized power supply devices designed to meet high power output requirements in a compact size. They are widely used in equipment and scenarios with stringent space constraints. These power supplies utilize advanced circuit design and component integration technology to precisely integrate core components such as power management modules, energy storage units, and power conversion components, significantly reducing overall size while ensuring stable output voltage and current. In practical applications, ultra-miniature power supplies can serve as core power supply components for small electronic products such as drones, smart wearable devices, and micro-robots, providing continuous and stable power support for equipment operation.

[0003] Despite significant progress in functional integration and size control of ultra-small power supplies, heat dissipation has increasingly become a key bottleneck restricting performance improvement. Due to the high integration of internal components, the heat generated during power conversion and energy storage is difficult to dissipate quickly, leading to a sharp rise in internal temperature. Traditional heat dissipation methods, such as simple metal casings or small heat sinks, are insufficient to meet the heat dissipation requirements of ultra-small power supplies. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an ultra-small power supply with a honeycomb heat dissipation structure to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an ultra-small power supply with a honeycomb heat dissipation structure, including a housing. A cover plate is fixedly installed on the top of the housing by bolts. A cooling fan is embedded in the top of the cover plate. Two symmetrically arranged assembly plates are fixedly installed on the inner wall of the housing by bolts. Two sets of battery bodies corresponding to each other are fixedly installed between several assembly plates. The output end of the cooling fan corresponds to the battery body. A grid-type partition plate is fixedly connected between the two assembly plates. The grid-type partition plate is located between the two sets of battery bodies. A honeycomb bracket is fixedly connected to the top and bottom surfaces of the grid-type partition plate. A honeycomb locking frame is provided on the side of the two honeycomb brackets away from the grid-type partition plate. The inner walls of the two honeycomb locking frames are respectively attached to the two sets of battery bodies. Several symmetrically arranged locking bolts are rotatably connected to one side of each honeycomb locking frame. The threaded part of the several locking bolts is threadedly connected to the honeycomb bracket.

[0007] Preferably, one side of the honeycomb bracket has several symmetrically arranged threaded holes, and the screw portions of several locking bolts are threadedly connected to the honeycomb bracket through the threaded holes.

[0008] Preferably, in any of the above embodiments, a heat-conducting plate is fixedly connected to both the left and right sides of the grid-type partition plate, and a number of linear array heat dissipation fins are fixedly connected to the side of each heat-conducting plate away from the grid-type partition plate. The grid-type partition plate, the heat-conducting plate and the heat dissipation fins are all made of aluminum alloy.

[0009] Preferably, in any of the above embodiments, the honeycomb bracket and the honeycomb locking frame are both made of aluminum alloy, and the bottom surface of the honeycomb locking frame is in contact with the top surface of the honeycomb bracket.

[0010] Preferably, in any of the above embodiments, the bottom surface of the honeycomb locking frame is fixedly connected with a plurality of linearly arrayed L-shaped card plates, and the plurality of L-shaped card plates are engaged with the honeycomb bracket.

[0011] Preferably, in any of the above solutions, a plurality of linearly arrayed heat dissipation holes are provided through both the left and right sides of the casing, and each of the plurality of heat dissipation holes corresponds to a heat-conducting plate.

[0012] Preferably, in any of the above solutions, the bottom surface of the cover plate is fixedly connected with a number of symmetrically arranged positioning pins, and the cover plate is engaged with the housing through the positioning pins.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Addressing the challenge of heat dissipation in ultra-small power supplies, this device employs a multi-layered heat dissipation structure. The cooling fan on top of the cover actively expels heat, forming air convection channels with the ventilation holes on both sides of the casing to accelerate heat dissipation. The heat-conducting plates and cooling fins on both sides of the grid-type partition plate quickly conduct heat generated by the battery body, increasing the heat dissipation area. The honeycomb bracket and honeycomb locking frame not only secure the battery body, but their unique honeycomb structure also increases the contact area with air, improving natural heat dissipation efficiency. The combined use of multiple heat dissipation methods, compared to traditional single-method cooling, can more quickly and effectively reduce the internal temperature of the power supply, preventing performance degradation and component aging caused by heat accumulation, and ensuring stable operation of the power supply.

[0015] 2. The assembly plate, grid-type partition plate, honeycomb bracket, and honeycomb locking frame work together to construct a stable battery installation system. The honeycomb bracket and honeycomb locking frame are securely fixed to the battery body through the connection of locking bolts and threaded holes, and the engagement of the L-shaped clamping plate with the honeycomb bracket, preventing displacement due to vibration during power supply operation. Positioning pins ensure a tight fit between the cover plate and the housing, further enhancing the overall structural stability. This robust installation method not only ensures the safety of the battery body in complex operating environments but also ensures that all heat dissipation components are in close contact with the battery body, maintaining good heat conduction and extending the service life of the ultra-small power supply.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0024] like Figures 1 to 6 As shown, an ultra-small power supply with a honeycomb heat dissipation structure includes a housing 1. A cover plate 2 is fixedly installed on the top of the housing 1 by bolts. A cooling fan 3 is embedded in the top of the cover plate 2. Two symmetrically arranged assembly plates 4 are fixedly installed on the inner wall of the housing 1 by bolts. Two sets of battery bodies 5, corresponding to each other, are fixedly installed between several assembly plates 4. The output end of the cooling fan 3 corresponds to the battery body 5. A grid-type partition plate 6 is fixedly connected between the two assembly plates 4. The grid-type partition plate 6 is located between the two sets of battery bodies 5. A honeycomb bracket 7 is fixedly connected to the top and bottom surfaces of the grid-type partition plate 6. A honeycomb locking frame 8 is provided on the side of the two honeycomb brackets 7 away from the grid-type partition plate 6. The inner walls of the two honeycomb locking frames 8 are respectively attached to the two sets of battery bodies 5. Several symmetrically arranged locking bolts 9 are rotatably connected to one side of each honeycomb locking frame 8. The screw parts of the several locking bolts 9 are threadedly connected to the honeycomb bracket 7.

[0025] As an optional technical solution of this utility model, a plurality of symmetrically arranged threaded holes 10 are provided on one side of the honeycomb bracket 7. The screw portions of a plurality of locking bolts 9 are all threadedly connected to the honeycomb bracket 7 through the threaded holes 10. The symmetrically arranged threaded holes 10 on one side of the honeycomb bracket 7 cooperate with the locking bolts 9 to provide a stable fixing method for the honeycomb locking frame 8. By screwing the screw portions of the locking bolts 9 into the threaded holes 10, the honeycomb bracket 7 and the honeycomb locking frame 8 can be tightly connected, thereby firmly fixing the battery body 5.

[0026] As an optional technical solution of this utility model, a heat-conducting plate 11 is fixedly connected to both the left and right sides of the grid-type partition plate 6. Each heat-conducting plate 11 has a plurality of linearly arrayed heat dissipation fins 12 fixedly connected to the side away from the grid-type partition plate 6. The grid-type partition plate 6, the heat-conducting plates 11, and the heat dissipation fins 12 are all made of aluminum alloy. The use of aluminum alloy for the heat-conducting plates 11 and heat dissipation fins 12 on both sides of the grid-type partition plate 6 fully utilizes the excellent thermal conductivity of aluminum alloy. The heat-conducting plates 11 can quickly conduct the heat generated by the battery body 5 to the heat dissipation fins 12, and the heat dissipation fins 12 accelerate the heat dissipation rate by increasing the contact area with air.

[0027] As an optional technical solution of this utility model, both the honeycomb bracket 7 and the honeycomb locking frame 8 are made of aluminum alloy. The bottom surface of the honeycomb locking frame 8 is in contact with the top surface of the honeycomb bracket 7. The use of aluminum alloy for both the honeycomb bracket 7 and the honeycomb locking frame 8 provides both good thermal conductivity and mechanical strength. The aluminum alloy material helps to conduct away the heat generated by the battery body 5, assisting in heat dissipation; at the same time, its high mechanical strength can withstand the weight of the battery body 5 and the pressure that may be applied from the outside, ensuring that the bracket and locking frame are not easily deformed when fixing the battery body 5.

[0028] As an optional technical solution of this utility model, the bottom surface of the honeycomb locking frame 8 is fixedly connected with several linearly arrayed L-shaped clamping plates 13. Each L-shaped clamping plate 13 engages with the honeycomb bracket 7. The engagement of the L-shaped clamping plates 13 on the bottom surface of the honeycomb locking frame 8 with the honeycomb bracket 7 further enhances the stability of the connection, building upon the fixing by the locking bolts 9. The engaging structure of the L-shaped clamping plates 13 restricts the horizontal displacement of the honeycomb locking frame 8, preventing it from shaking or shifting due to vibration or other reasons, thus forming a double-fixing guarantee with the threaded connection.

[0029] As an optional technical solution of this utility model, a plurality of linearly arrayed heat dissipation holes 14 are provided through both the left and right sides of the housing 1. Each heat dissipation hole 14 corresponds to a heat-conducting plate 11. The heat dissipation holes 14 on the left and right sides of the housing 1 are correspondingly arranged with the heat-conducting plate 11, constructing an efficient heat dissipation channel. When the heat-conducting plate 11 and the heat dissipation fins 12 conduct heat to the interior of the housing 1, the heat dissipation holes 14 allow hot air to be quickly exhausted to the external environment. Simultaneously, cool air from the outside enters the housing 1 through the heat dissipation holes 14, forming air convection. This convection heat dissipation method can accelerate heat exchange and dissipation. Combined with the active heat dissipation of the cooling fan 3, it significantly improves the heat dissipation efficiency of the ultra-small power supply, prevents heat accumulation inside the power supply, effectively reduces the internal temperature, and ensures stable and reliable operation of the power supply under various operating conditions.

[0030] As an optional technical solution of this utility model, a number of symmetrically arranged positioning pins 15 are fixedly connected to the bottom surface of the cover plate 2. The cover plate 2 is engaged with the housing 1 through the positioning pins 15. The positioning pins 15 on the bottom surface of the cover plate 2 engage with the housing 1, providing precise positioning and a stable connection for the installation of the cover plate 2. When installing the cover plate 2, the positioning pins 15 can quickly and accurately guide the cover plate 2 to align with the housing 1, avoiding problems such as excessive gaps or component interference caused by installation deviations, and improving assembly efficiency.

[0031] An ultra-miniature power supply with a honeycomb heat dissipation structure operates on the following principle:

[0032] 1): The cooling fan 3 on the top of the cover plate 2 can actively dissipate heat and form an air convection channel with the heat dissipation holes 14 on both sides of the casing 1 to accelerate heat dissipation.

[0033] 2): The heat-conducting plates 11 and heat dissipation fins 12 on the left and right sides of the grid-type partition plate 6 can quickly conduct the heat generated by the battery body 5 and increase the heat dissipation area.

[0034] 3) The honeycomb bracket 7 and honeycomb locking bracket 8 not only secure the battery body 5, but their unique honeycomb structure also increases the contact area with air, improving natural heat dissipation efficiency. Multiple heat dissipation methods work together, which, compared to traditional single heat dissipation methods, can reduce the internal temperature of the power supply more quickly and effectively.

[0035] In summary, this ultra-small power supply with a honeycomb heat dissipation structure employs a multi-layered heat dissipation structure. The cooling fan 3 on the top of the cover plate 2 can actively dissipate heat, forming an air convection channel with the heat dissipation holes 14 on both sides of the casing 1, accelerating heat dissipation. The heat-conducting plates 11 and heat dissipation fins 12 on the left and right sides of the grid-type partition plate 6 can quickly conduct the heat generated by the battery body 5, increasing the heat dissipation area. The honeycomb bracket 7 and honeycomb locking frame 8 not only fix the battery body 5, but their unique honeycomb structure also increases the contact area with air, improving natural heat dissipation efficiency. The multiple heat dissipation methods work together, which, compared with traditional single heat dissipation methods, can more quickly and effectively reduce the internal temperature of the power supply, avoid performance degradation and component aging caused by heat accumulation, and ensure stable operation of the power supply. The assembly plate 4, grid-type partition plate 6, honeycomb bracket 7 and honeycomb locking frame 8 work together to construct a stable battery installation system. The honeycomb bracket 7 and honeycomb locking bracket 8 are connected by locking bolts 9 and threaded holes 10, and the L-shaped clamping plate 13 is engaged with the honeycomb bracket 7, firmly fixing the battery body 5 and preventing it from shifting due to vibration during power operation. The positioning pin 15 tightly engages the cover plate 2 with the housing 1, further enhancing the overall structural stability. This robust installation method not only ensures the safety of the battery body 5 in complex operating environments but also ensures that all heat dissipation components are in close contact with the battery body 5, maintaining good heat conduction and extending the service life of the ultra-small power supply.
