Description

Technical Field

[0001] This utility model relates to the field of fast charging device technology, and in particular to a high-rate energy storage power supply multi-mode fast charging device. Background Technology

[0002] Currently, fast charging devices typically employ two methods to dissipate heat generated by the internal circuit board. One method uses a built-in fan and metal heat sink for heat dissipation. However, after prolonged use, the fan easily accumulates dust, and because it is built-in, it is inconvenient for users to remove it for cleaning, resulting in reduced heat dissipation efficiency. The other method uses multiple heat dissipation honeycomb holes on the outer casing. However, using honeycomb holes to dissipate heat generated by the internal circuit board has the disadvantage of slow heat dissipation and low heat dissipation efficiency. Therefore, the heat dissipation structure of existing fast charging devices needs to be improved. Utility Model Content

[0003] This utility model aims to provide a high-rate energy storage power supply multi-mode fast charging device to solve the problems mentioned in the background art. One method is to use a built-in fan and metal heat sink for heat dissipation, but after long-term use, the fan is prone to dust accumulation, and because the fan is built-in, it is inconvenient for users to disassemble and clean it, resulting in a decrease in heat dissipation efficiency. Another method is to use multiple heat dissipation honeycomb holes on the outer shell, but the method of using honeycomb holes to dissipate the heat generated by the internal circuit board has the problem of slow heat dissipation and low heat dissipation efficiency.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A high-rate energy storage power supply multi-mode fast charging device includes a shell, an input plug, an output plug, a circuit board, and a heat dissipation component; the circuit board is fixedly disposed inside the shell, the input plug is located at one end of the shell and electrically connected to the circuit board, the output plug is located at the other end of the shell and electrically connected to the circuit board, the heat dissipation component is fixedly disposed on the top of the shell and electrically connected to the circuit board, the heat dissipation component includes an electric fan, heat dissipation fins, and a semiconductor cooling chip, the heat dissipation fins are fixedly connected to the bottom of the electric fan, the semiconductor cooling chip is fixedly connected to the bottom of the heat dissipation fins, and several copper rods are welded to the bottom of the semiconductor cooling chip, and the several copper rods at the bottom of the semiconductor cooling chip are all embedded inside the shell and welded to the circuit board.

[0005] In some embodiments, the input plug is electrically connected to the circuit board via a first line, the output plug is electrically connected to the circuit board via a second line, and the heat dissipation component is electrically connected to the circuit board via a third line.

[0006] In some embodiments, the heat sink fins are screwed to the electric fan, and the semiconductor cooling chip is welded to the heat sink fins.

[0007] In some embodiments, connecting pieces are fixedly provided on both sides of the heat dissipation fins, and the connecting pieces on both sides of the heat dissipation fins are connected to the top screws of the housing.

[0008] In some embodiments, a power indicator light is fixedly provided on the side of the housing, and the power indicator light is electrically connected to the circuit board.

[0010] In some embodiments, a power switch is fixedly disposed on the top of the housing, and the power switch is electrically connected to the heat dissipation assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the user can activate the heat dissipation assembly to cool the circuit board. During this process, a thermoelectric cooler operates, using a thermoelectric cooler composed of N-type and P-type semiconductor materials forming a thermocouple. When direct current passes through these materials, one end absorbs heat (cold end), while the other end releases heat (hot end). The bottom of the thermoelectric cooler is the cold end, and the top is the hot end. During operation, the cold end of the thermoelectric cooler is welded to the circuit board via several copper rods embedded inside the casing. These copper rods absorb heat from the circuit board. After absorbing heat, the hot end of the thermoelectric cooler releases the heat to the heat dissipation fins. The heat dissipation fins diffuse the received heat, and an electric fan further dissipates the heat, promoting rapid heat dissipation and enabling the heat dissipation assembly to efficiently cool the circuit board inside the casing. In this invention, the heat dissipation component can quickly dissipate heat from the circuit board inside the casing, ensuring that the circuit board will not malfunction due to heat dissipation problems during operation, which has the advantages of high efficiency and practicality.

[0022] This utility model provides the following technical solution: a high-rate energy storage power supply multi-mode fast charging device 100, including a housing 10, an input plug 20, an output plug 30, a circuit board 40, and a heat dissipation component 50; the circuit board 40 is fixedly disposed inside the housing 10, the input plug 20 is located at one end of the housing 10 and electrically connected to the circuit board 40, the output plug 30 is located at the other end of the housing 10 and electrically connected to the circuit board 40, the heat dissipation component 50 is fixedly disposed on the top of the housing 10 and electrically connected to the circuit board 40, the heat dissipation component 50 includes an electric fan 501, heat dissipation fins 502, and a semiconductor cooling chip 503, the heat dissipation fins 502 are fixedly connected to the bottom of the electric fan 501, the semiconductor cooling chip 503 is fixedly connected to the bottom of the heat dissipation fins 502, and a plurality of copper rods 5031 are welded to the bottom of the semiconductor cooling chip 503, and the plurality of copper rods 5031 at the bottom of the semiconductor cooling chip 503 are all embedded inside the housing 10 and welded to the circuit board 40.

[0023] This embodiment provides a high-rate energy storage power supply multi-mode fast charging device 100. When using this fast charging device, the input plug 20 is inserted into a household power outlet, and the output plug 30 is inserted into the charging port of the object being charged. The circuit board 40 controls the power output to quickly charge the object. The circuit board 40 generates significant heat during operation. The user can activate the heat dissipation component 50 to cool the circuit board 40. While the heat dissipation component 50 is cooling the circuit board 40, a thermoelectric cooler 503 operates. The thermoelectric cooler 503 uses N-type and P-type semiconductor materials to form a thermocouple pair. When direct current passes through these two semiconductor materials, one end absorbs heat (i.e., the cold end), while the other end releases heat (i.e., the hot end). The bottom of the thermoelectric cooler 503 is the cold end, and the top is the hot end. When the thermoelectric cooler 503 is operating, the cold end at the bottom of the thermoelectric cooler 503 is connected to several copper... Rods 5031 are embedded inside the housing 10 and soldered to the circuit board 40. This allows several copper rods 5031 at the cold end of the bottom of the thermoelectric cooler 503 to absorb heat from the circuit board 40. After absorbing heat at the cold end of the thermoelectric cooler 503, the heat is released from the hot end of the thermoelectric cooler 503 and transferred to the heat dissipation fins 502. The heat dissipation fins 502 can diffuse the received heat to dissipate heat, and an electric fan 501 further dissipates the heat on the heat dissipation fins 502, promoting rapid heat dissipation. This allows the heat dissipation assembly 50 to efficiently dissipate heat from the circuit board 40 inside the housing 10. In this invention, the heat dissipation assembly 50 can quickly dissipate heat from the circuit board 40 inside the housing 10, ensuring that the circuit board 40 will not malfunction due to heat dissipation problems during operation. This design is both efficient and practical.
