Description

Technical Field

[0001] This utility model relates to the field of mobile power supply technology, and in particular to a mobile power supply structure. Background Technology

[0002] A power bank, also known as a portable charger, is a portable device with a built-in battery. It is mainly used to provide power to various electronic devices and is an indispensable choice for extending the usage time of electronic devices during outdoor activities and travel. It is especially suitable for occasions where it is not possible to connect to a traditional power outlet.

[0003] Most existing power banks use air cooling for heat dissipation. The effectiveness of air cooling is highly dependent on the airflow direction. Areas near the fan outlet have good heat dissipation, while corners far from the fan tend to form high-temperature areas that are difficult to dissipate heat. This temperature difference can lead to uneven aging of the battery cells inside the battery module and shorten the cycle life. Utility Model Content

[0004] The purpose of this invention is to provide a mobile power supply structure that addresses the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A portable power bank structure includes a mounting housing, which is divided into a power supply shell and a top cover shell mounted on top of the power supply shell. A battery module is installed inside the power supply shell, and a connection panel is installed on the front side of the power supply shell. A heat dissipation structure is provided between the power supply shell and the top cover shell. A power slot is formed inside the power supply shell, and the battery module is installed in the power slot. Multiple metal heat-conducting plates are also installed in the power slot, and the inner wall of the metal heat-conducting plates is in contact with the outer wall of the battery module. A bottom water-cooling cavity is formed in the metal heat-conducting plates, and a first bottom water-cooling head and a second bottom water-cooling head communicating with the bottom water-cooling cavity are installed. A radiator structure is provided on the top cover shell, and the radiator structure is respectively connected to the first bottom water-cooling head and the second bottom water-cooling head of the metal heat-conducting plates.

[0007] Furthermore: the metal heat-conducting plate is divided into a first metal heat-conducting plate, a second metal heat-conducting plate, a third metal heat-conducting plate and a fourth metal heat-conducting plate, wherein a bottom water-cooling pipe is connected between the second bottom water-cooling head of the third metal heat-conducting plate and the first bottom water-cooling head of the fourth metal heat-conducting plate.

[0008] Furthermore: the radiator structure includes a first radiator plate, a second radiator plate and a third radiator plate, each of which is equipped with a pump body, and each of which is provided with a first top water cooling head and a second top water cooling head.

[0009] Furthermore: the first radiator plate is connected to the first metal heat-conducting plate, the second radiator plate is connected to the second metal heat-conducting plate, and the third radiator plate is connected to the third metal heat-conducting plate and the fourth metal heat-conducting plate respectively; the connection method is water-cooled pipes.

[0010] Furthermore, cooling fans are installed on the top of the first, second, and third radiators.

[0011] Furthermore: the third metal heat-conducting plate includes a top plate, a first bottom water-cooling head and a second bottom water-cooling head are respectively installed on the top plate, and a plurality of spaced bottom plates are formed at the bottom of the top plate, and the bottom water-cooling cavity of the top plate is connected to the bottom water-cooling cavity of the bottom plate.

[0012] Furthermore: there is a gap between the bottom plates.

[0013] Furthermore, the connection panel is provided with a first connection area, a second connection area and a third connection area arranged at intervals, and the first connection area, the second connection area and the third connection area are respectively connected to the power module.

The bottom water-cooling cavity is connected to the radiator structure of the upper cover shell through the first bottom water-cooling head, the second bottom water-cooling head, and the radiator structure, forming a closed-loop circulation system. The coolant flows between the metal heat-conducting plate and the radiator, achieving efficient heat transfer. The radiator structure is integrated into the upper cover shell, utilizing the principle of air convection to dissipate the heat carried by the coolant to the external environment, further enhancing the heat dissipation effect.

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1-3 As shown, a mobile power bank structure includes a mounting housing 1, which is divided into a power housing 11 and a top cover 12 mounted on top of the power housing 11. A battery module 13 is installed inside the power housing 11, and a connecting panel 15 is installed on the front side of the power housing 11. A heat dissipation structure 2 is provided between the power housing 11 and the top cover 12. A power slot 14 is formed inside the power housing 11, and the battery module 13 is installed in the power slot 14. The power slot 14 is also equipped with multiple metal heat-conducting plates, and the inner wall of the metal heat-conducting plates is in contact with the outer wall of the battery module 13. A bottom water-cooling cavity 20 is formed in the metal heat-conducting plates, and a first bottom water-cooling head 25 and a second bottom water-cooling head 26 communicating with the bottom water-cooling cavity 20 are installed. A cooling radiator structure 3 is provided on the top cover 12, and the cooling radiator structure 3 is respectively connected to the first bottom water-cooling head 25 and the second bottom water-cooling head 26 of the metal heat-conducting plates.

[0032] The inner wall of the metal heat-conducting plate inside the power supply compartment 14 is tightly fitted to the outer wall of the battery module 13. Utilizing the high thermal conductivity of the metal material, the heat generated by the battery module 13 is rapidly conducted to the bottom water-cooling cavity 20. The bottom water-cooling cavity 20 is connected to the radiator structure 3 of the upper cover shell 12 through the first bottom water-cooling head 25 and the second bottom water-cooling head 26, forming a closed-loop circulation system. The coolant flows between the metal heat-conducting plate and the radiator, achieving efficient heat transfer. The radiator structure 3 is integrated into the upper cover shell 12, utilizing the principle of air convection to dissipate the heat carried by the coolant to the external environment, further enhancing the heat dissipation effect. The radiator layout of the upper cover shell 12 is more conducive to natural convection and does not occupy the internal space of the power supply shell 11, improving the structural compactness.

[0033] Specifically, the metal heat-conducting plates are divided into a first metal heat-conducting plate 21, a second metal heat-conducting plate 22, a third metal heat-conducting plate 23, and a fourth metal heat-conducting plate 24. A bottom water-cooling pipe connects the second bottom water-cooling head 26 of the third metal heat-conducting plate 23 to the first bottom water-cooling head 25 of the fourth metal heat-conducting plate 24. These multiple metal heat-conducting plates are subdivided into three modules. The four sets of metal heat-conducting plates can each correspond to different areas of the battery cell, achieving a tight, one-to-one fit through customized shapes. The third metal heat-conducting plate 23 and the fourth metal heat-conducting plate 24 typically correspond to the high-heat-generating areas of the battery module 13, and the two are directly connected through the bottom water-cooling pipe, forming a module with localized small-circulation.

[0034] Furthermore, the radiator structure 3 includes a first radiator plate 31, a second radiator plate 32, and a third radiator plate 33. A pump body 34 and a cooling fan 35 are respectively mounted on the first radiator plate 31, the second radiator plate 32, and the third radiator plate 33. A first top water-cooling head 36 and a second top water-cooling head 37 are respectively provided on the first radiator plate 31 and the second radiator plate 32. The first radiator plate 31 and the second radiator plate 32 respectively dissipate liquid heat from the bottom water-cooling cavity 20 of the first and second metal heat-conducting plates 22. The third radiator plate 33 dissipates heat from the third metal heat-conducting plate 23 and the fourth metal heat-conducting plate 24 forming the module; thus forming three independent water-cooling systems.

[0035] In this embodiment, if one system malfunctions, such as the pump 34 of the first radiator plate 31 stopping, the remaining two systems can still operate normally: the second radiator plate 32 continues to dissipate heat for the second metal heat-conducting plate 22, and the third radiator plate 33 maintains the heat dissipation requirements of the high-heat-generating module, ensuring that the core function of the power bank is not interrupted. The independent system design makes fault diagnosis more convenient, and the faulty system can be directly located through temperature monitoring. For example, if the temperature in a certain area rises abnormally, it corresponds to a malfunction in the radiator system, without having to disassemble the entire water-cooling structure.

[0036] The battery module area to be cooled by the three water-cooling systems is divided into three temperature zones, and a corresponding temperature sensor is installed in each of the three temperature zones of the battery module. The individual temperature sensors, pump body 34, and cooling fan 35 are connected by a signal control board. When the temperature of the corresponding temperature zone does not exceed the preset threshold, the cooling operation can be paused through the temperature sensor to reduce energy consumption; conversely, when the temperature of the corresponding temperature zone exceeds the preset threshold, the corresponding water-cooling system will operate through the temperature sensor to ensure efficient heat dissipation.

[0037] Specifically, the first radiator plate 31 is connected to the first metal heat-conducting plate 21, the second radiator plate 32 is connected to the second metal heat-conducting plate 22, and the third radiator plate 33 is connected to the third metal heat-conducting plate 23 and the fourth metal heat-conducting plate 24 respectively; the connection method is a flexible water-cooling pipe; the first top water-cooling head 36 of the first radiator plate 31 is connected to the first bottom water-cooling head 25 of the first metal heat-conducting plate 21 through a water-cooling pipe to realize liquid flow; the second bottom water-cooling head 26 of the metal heat-conducting plate and the second top water-cooling head 37 of the first radiator plate 31 form a circulation; after the coolant exchanges heat with the first metal heat-conducting plate 21, it is introduced into the first radiator plate 31 and cooled by the cooling fan 35. Then, the cooled coolant continues to enter the first radiator plate 31 for heat exchange, realizing heat dissipation circulation; the heat dissipation between the second radiator plate 32 and the second metal heat-conducting plate 22, and the heat dissipation principle of the third radiator plate 33 connected to the third metal heat-conducting plate 23 and the fourth metal heat-conducting plate 24 respectively are the same, and will not be elaborated here.

[0038] Furthermore, the third metal heat-conducting plate 23 includes a top plate 27, a first bottom water-cooling head 25 and a second bottom water-cooling head 26 respectively mounted on the top plate 27, and a plurality of spaced bottom plates 28 formed on the bottom of the top plate 27, with the bottom water-cooling cavity 20 of the top plate 27 communicating with the bottom water-cooling cavity 20 of the bottom plates 28. There are gaps between the bottom plates 28. The multiple spaced bottom plates 28 formed on the bottom of the top plate 27 can directly fit the multiple battery cells of the battery module 13, and the gaps formed can be staggered from the connecting device, ensuring thermal conductivity while preventing collision with the connecting device.

[0039] Furthermore, the connection panel 15 is provided with a first connection area 16, a second connection area 17, and a third connection area 18 arranged at intervals, which are respectively connected to the power module. The bottom plate 28 is inserted into the gap between the first connection area 16 and the second connection area 17, and the gap between the second connection area 17 and the third connection area 18. The first connection area 16, the second connection area 17, and the third connection area 18 are for different interface types, including USB interface, triangular interface, and control button; the gaps formed are staggered from the connection areas to ensure heat conduction performance and prevent collision with the connection areas.

[0040] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0041] The above description is only a preferred embodiment of this utility model.

The content of this specification should not be construed as a limitation of this utility model.
