Description

Technical Field

[0001] This disclosure relates to the field of power adapter technology, and specifically to a waterproof power supply box with an integrated heat dissipation structure. Background Technology

[0002] A power supply box, also known as an external power supply, is a voltage conversion device for small portable electronic devices and appliances, commonly found in small electronic products such as laptops and computer mainframes. Its function is to convert AC mains power into a stable low voltage of approximately 5 to 20 volts, enabling these electronic products to operate normally. It typically consists of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board.

[0003] Due to manufacturing limitations, existing power supply boxes require the heatsink to be manually pressed into the notch of the power supply box, resulting in a large gap between the power supply box and the heatsink, poor waterproofing, and a complex installation process. Utility Model Content

[0004] This disclosure provides a waterproof power supply box with an integrated heat dissipation structure. The power supply box contains an energy storage module, and the outer shell of the power supply box is provided with a heat-conducting plate. The heat-conducting plate and the outer shell of the power supply box are integrally formed by injection molding, which can save labor costs and improve the waterproof effect of the outer shell of the power supply box.

[0005] To achieve the aforementioned objectives, this disclosure provides the following technical solution:

[0006] A waterproof power supply box with an integrated heat dissipation structure includes a power supply box shell, a transformer module, an energy storage module, a circuit board, an input terminal, and an output terminal. The transformer module and the energy storage module are mounted on the circuit board. A heat-conducting plate is also provided on the power supply box shell. The heat-conducting plate and the power supply box shell are integrally formed by injection molding.

[0007] Preferably, the energy storage module uses gallium nitride (GaN) material devices, which can effectively reduce heat generation in the on-state, reduce the size of the energy storage module, and improve the utilization rate of internal space.

[0008] Preferably, a heat-conducting frame is provided on the circuit board. The heat-conducting frame absorbs the heat emitted by the circuit board and the transformer module, which can effectively reduce the temperature of the circuit board and the transformer module and prevent them from stopping work or even being damaged due to high temperature protection.

[0009] Preferably, the energy storage module is in contact with the heat-conducting sheet via thermally conductive adhesive, and the heat-conducting frame is in contact with the heat-conducting sheet via thermally conductive adhesive. The thermally conductive adhesive can transfer the heat of the heat-conducting frame to the heat-conducting sheet for heat dissipation. The thermal conductivity of the thermally conductive adhesive is greater than that of air, which can dissipate heat more effectively.

[0010] Preferably, a support block is provided at the bottom of the energy storage module, and the energy storage module is fixed together with the support block inside the power box shell with insulating glue, which can avoid the impact of vibration on the energy storage module during carrying.

[0011] Preferably, the lower part of the energy storage module contacts the circuit board through thermally conductive adhesive. The thermally conductive adhesive can transfer the heat emitted by the energy storage module to the circuit board, and then dissipate heat through the thermally conductive frame, which can assist in the heat dissipation of the energy storage module.

[0012] Preferably, the heat-conducting sheet and the power supply box shell are integrally molded using a die-casting injection molding process, which can improve the airtightness of the heat-conducting sheet and the power supply box shell, and has a certain waterproof effect, which can meet most daily waterproof needs.

[0013] Preferably, the heat-conducting plate is a metal heat sink or an alloy heat sink. Metal or alloy has good thermal conductivity, which can enhance the heat dissipation of the power supply box.

[0014] Preferably, a display screen is provided on the outer shell of the power supply box. The display screen can show the remaining power of the energy storage module, making it convenient for users to plan their power consumption.

[0015] The beneficial effects of this disclosure are as follows:

[0016] Portable power supply boxes, due to their size limitations, cannot have built-in cooling fans for heat dissipation like computer power supplies. Therefore, this disclosure provides a heat-conducting plate on the outer shell of the power supply box. The heat-conducting plate helps to dissipate the heat inside the power supply box into the air, preventing heat accumulation inside the power supply box. At the same time, in order to improve heat dissipation efficiency, thermally conductive adhesive is used to directly contact the heat-conducting plate and the power module. The thermal conductivity of the thermally conductive adhesive is higher than that of air, which can effectively improve heat dissipation efficiency and enhance the applicability and safety of the portable power supply box.

[0017] Secondly, this disclosure uses a die-casting injection molding process to integrally form the heat-conducting sheet and the power box shell, which changes the existing technology that uses manual pressing to form the heat-conducting sheet, saving labor. Moreover, integral molding can ensure that there is no need to leave gaps between the heat-conducting sheet and the power box shell. The formed power box shell has good waterproof performance, which can effectively improve safety and reduce the probability of accidents caused by water ingress into the power box.

Thermal conductive frame, 9. Support block, 10. Display screen.

[0030] A waterproof power supply box with an integrated heat dissipation structure includes a power supply box shell 1, a transformer module 2, an energy storage module 3, a circuit board 4, an input terminal 5, and an output terminal. The transformer module 2 and the energy storage module 3 are mounted on the circuit board 4. A heat-conducting sheet 6 is also provided on the power supply box shell 1. The heat-conducting sheet 6 and the power supply box shell 1 are integrally formed by injection molding. The energy storage module 3 is in contact with the heat-conducting sheet 6 through thermally conductive adhesive 7.

[0031] The energy storage module 3 uses gallium nitride material devices, which can effectively reduce heat generation in the conduction state, reduce the size of the energy storage module 3, and improve the utilization rate of internal space.

[0032] A heat-conducting frame 8 is provided on the circuit board 4. The heat-conducting frame 8 absorbs the heat emitted by the circuit board 4 and the transformer module 2, which can effectively reduce the temperature of the circuit board 4 and the transformer module 2, and prevent the high temperature protection from causing the circuit board 4 to stop working or even be damaged.

[0033] The energy storage module 3 is in contact with the heat-conducting sheet 6 through the thermally conductive adhesive 7, and the heat-conducting frame 8 is in contact with the heat-conducting sheet 6 through the thermally conductive adhesive 7. The thermally conductive adhesive 7 can transfer the heat of the heat-conducting frame 8 to the heat-conducting sheet 6 for heat dissipation. The thermal conductivity of the thermally conductive adhesive 7 is greater than that of air, so it can dissipate heat more effectively.

[0034] The energy storage module 3 has a support block 9 at its bottom. The energy storage module 3 is fixed inside the power box shell 1 together with the support block 9 by insulating glue, which can avoid the impact of vibration on the energy storage module 3 during carrying.

[0035] The lower part of the energy storage module 3 is in contact with the circuit board 4 through the thermal conductive adhesive 7. The thermal conductive adhesive 7 can transfer the heat emitted by the energy storage module 3 to the circuit board 4, and then dissipate heat through the thermal conductive frame 8, which can assist the energy storage module 3 in heat dissipation.

[0036] The heat-conducting plate 6 is a metal heat sink or an alloy heat sink. Metal or alloy has good thermal conductivity, which can enhance the heat dissipation of the power supply box.

[0037] The power box housing 1 is equipped with a display screen 10, which can display the remaining power of the energy storage module 3, making it convenient for users to plan their power consumption.

[0038] The beneficial effects of this disclosure are as follows:

[0039] Portable power supply boxes, due to their size considerations, cannot have built-in cooling fans for heat dissipation like computer power supplies. Therefore, this disclosure provides a heat-conducting plate 6 on the outer shell 1 of the power supply box. The heat-conducting plate 6 helps to dissipate the heat inside the power supply box into the air, preventing heat accumulation inside the power supply box. At the same time, in order to improve heat dissipation efficiency, thermally conductive adhesive 7 directly contacts the heat-conducting plate 6 and the power module. The thermal conductivity of thermally conductive adhesive 7 is higher than that of air, which can effectively improve heat dissipation efficiency and enhance the applicability and safety of the portable power supply box.

[0040] Secondly, this disclosure uses a die-casting injection molding process to integrally form the heat-conducting sheet 6 and the power box shell 1, which changes the existing technology that uses manual pressing to form the heat-conducting sheet 6, saving labor. Moreover, integral molding can ensure that there is no need to leave a gap between the heat-conducting sheet 6 and the power box shell 1. The formed power box shell 1 has good waterproof effect, which can effectively improve safety and reduce the probability of accidents caused by water ingress into the power box.

[0041] The usage and working methods of this disclosure are as follows:

[0042] This disclosure uses a die injection molding process to integrally form the heat-conducting sheet 6 and the power box shell 1, which can automatically fix the power box shell 1 and the heat sink. Moreover, there is no need to leave gaps between the heat-conducting sheet 6 and the power box, and the waterproof effect is good.

[0043] When in use, connect the input terminal 5 of the power supply box to the mains power and the output terminal of the power supply box to the exhibition host. At this time, the energy storage module 3 is in charging mode and is powered by the mains power from the output terminal. If the mains power is suddenly disconnected and the exhibition host is still working, the circuit board 4 will control the energy storage module 3 to supply power to the output terminal to ensure that the exhibition host will not stop directly. When the energy storage module 3 is powered, the heat emitted by the energy storage module 3 is transferred to the heat conduction sheet 6 through the thermal conductive adhesive 7 and then dissipated into the air by the heat conduction sheet 6.

[0044] Therefore, the waterproof power supply box with an integrated heat dissipation structure provided in this disclosure has an energy storage module 3 inside the power supply box and a heat-conducting plate 6 on the outer shell 1 of the power supply box. The heat-conducting plate 6 is in direct contact with the air, and the energy storage module 3 dissipates heat by contacting the heat-conducting plate 6 through the thermal adhesive 7. This can dissipate heat for the energy storage module 3 and reduce the safety hazards of the power supply box.

[0045] Therefore, the waterproof power supply box with an integrated heat dissipation structure provided in this disclosure has an energy storage module 3 inside the power supply box and a heat conduction sheet 6 on the outer shell 1 of the power supply box. The heat conduction sheet 6 and the outer shell 1 of the power supply box are integrally formed by injection molding, which can save labor costs and improve the waterproof effect of the outer shell 1 of the power supply box.
