Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to a power supply pack with heat dissipation function. Background Art

[0002] With the development and widespread application of portable power solutions, especially in the fields of outdoor operations, emergency rescue, and field exploration, high-capacity, high-power power backpacks are becoming more and more important as a mobile energy system. Such power backpacks usually have built-in battery packs consisting of multiple lithium-ion batteries or other types of energy storage components to provide long-term and efficient power support for various devices. However, while achieving high energy density and continuous power supply, the heat dissipation problem of the power backpack has become an important factor restricting its reliability and safety.

[0003] In traditional technology, the heat dissipation design of the power backpack mainly focuses on the cooling of the internal components of the power supply, especially the heat management of the battery module. A common practice is to integrate a fan on the side or inside of the power backpack, such as the portable mobile power supply disclosed in patent CN202220345786.0. The main function of the fan is to directly cool the battery cell to ensure that the heat generated by the battery cell when working can be dissipated in time. In addition to the heat generated by the power supply itself, the staff who carry and use the power backpack will also be affected by the ambient temperature and the heat generated by the backpack itself, which may cause discomfort to the staff, reduce work efficiency, and even affect health and safety.

[0004] Therefore, there is also a battery backpack cooling device as disclosed in patent CN201921913856.2, in which the cooling fan blows directly outward (i.e., the back of the backpack). Although this cooling method can help the power supply dissipate heat to a certain extent, the blown wind does not have any diversion structure. Therefore, if the staff directly carries the power supply backpack, the air outlet of the fan will be covered, which not only affects the heat dissipation of the power supply, but also fails to provide heat dissipation for the staff, resulting in poor heat dissipation effect. Summary of the invention

[0005] The utility model aims to solve the problems in the prior art and provides a power supply package with a heat dissipation function, which can not only dissipate the heat for the power supply but also provide a heat dissipation effect for the staff.

DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0026] This embodiment provides a power pack with a heat dissipation function, such as Figures 1 to 7, including a backpack shell, a heat dissipation component and a power supply component, the backpack shell includes an outer cover 1 and a back cover 2 detachably connected to the outer cover 1, a backpack cavity is formed between the outer cover 1 and the back cover 2, the heat dissipation component and the power supply component are both installed in the backpack cavity, and the power supply component is electrically connected to a plurality of output sockets; the heat dissipation component includes a fan 3 and a guide shell 4, the guide shell 4 is installed on the back cover 2 and forms a guide cavity with the back cover 2, the fan 3 is installed in the guide cavity, the guide cavity is located at the bottom of the backpack cavity, the guide cavity is provided with an air inlet, the back cover 2 is provided with a plurality of air outlets 5, the air outlets 5 are connected to the guide cavity, the back cover 2 is provided with a groove 6 recessed from the outside to the backpack cavity, and the air outlet 5 is located below the groove 6.

[0027] Specifically, Figure 2 , Figure 3 and Figure 6 As shown, the groove 6 of the back cover 2 is recessed in the direction of the backpack cavity. Therefore, after the staff puts on the power backpack, a certain space will be reserved between the back cover 2. The size of this space depends on the size of the groove 6. In this embodiment, the groove 6 is set to have a certain length. The air outlet 5 of the fan 3 is located at the bottom of the groove 6, that is, Figure 2 In the position shown, when the wind is discharged, the direction of the wind will be blown upward from the air outlet 5, so the air outlet of the fan 3 will not be blocked, and the back of the staff can be cooled. Furthermore, since the air inlet of the fan 3 is located in the backpack cavity, the heat generated by the power supply assembly in the backpack cavity can be taken away, thereby achieving the effect of cooling the power supply assembly. This embodiment achieves the purpose of cooling both the power supply assembly and the back of the staff through the setting of the air outlet structure of the fan 3 and the structural setting of the back cover 2, as well as the cooperation between the two, and has higher practicality than the prior art.

[0028] Furthermore, the present embodiment is also provided with a guide housing 4, such as Figure 4 , Figure 5 and Figure 7As shown, the guide shell 4 is used to assist the guiding of the wind flow. The guide cavity of the guide shell 4 includes an installation cavity 18 of the fan 3 and an air outlet cavity 19. The air inlet is arranged at one end of the installation cavity 18. After the fan 3 is working, the air flow in the backpack cavity enters the installation cavity 18 from the air inlet, and then under the drive of the fan 3, the air flow flows to the air outlet cavity 19, and then is blown out from the air outlet 5, thereby realizing the guidance of the wind flow, taking away the air in the backpack cavity and blowing it outside the backpack cavity, effectively dissipating the heat for the power supply component. Although the wind blown out from the air outlet 5 carries a certain amount of heat, because the heat has formed an airflow, and the airflow blown out of the backpack cavity contacts the external air and has begun to dissipate heat, the temperature of the airflow blown to the staff is relatively low relative to the temperature in the backpack cavity, and even if the formed airflow has a certain temperature, it can dissipate heat for the staff. Therefore, this embodiment can achieve the effect of dual heat dissipation through the arrangement of the guide shell 4 and the air outlet 5, which is more suitable for outdoor use by staff.

[0029] like Figure 4 As shown, in terms of assembly, the back cover 2 is also provided with a bracket 7 for assembling the fan 3, and the bracket 7 is provided with a U-shaped slot (not shown in the figure), and the fan 3 can be directly snapped into the U-shaped slot, and then the guide shell 4 is installed to the back cover 2, so that the fan 3 can be fixed in the installation cavity 18, and the assembly is convenient; and the outer periphery of the guide shell 4 is provided with a plurality of mounting ears 11, and the mounting ears 11 are provided with through holes 12, and the back cover 2 is provided with screw holes 13 corresponding to the through holes 12, and the external screws pass through the through holes 12 and are screwed to the screw holes 13, thereby fixing the guide shell 4 to the back cover 2. In addition, the back cover 2 of this embodiment is provided with a plurality of positioning posts 10, such as Figure 4 As shown, the outer cover 1 is provided with corresponding positioning slots. During assembly, the positioning post 10 is inserted into the corresponding positioning slot, and then the positioning post 10 is penetrated by a screw and screwed into the positioning slot, so that the back cover 2 and the outer cover 1 are assembled together.

[0030] Further, such as Figure 1 As shown, a handle 16 is provided on the top of the back cover 2 of this embodiment, and shoulder strap rings 17 are provided around the back cover 2. The handle 16 is convenient for the staff to carry the power pack, and the shoulder strap rings 17 can be equipped with a shoulder strap for the staff to carry it easily.

[0031] The power supply assembly of this embodiment includes a battery cell (not shown in the drawings), a power switch 14 and a fan switch 15. The power switch 14 is used to connect the output socket to the battery cell. The fan switch 15 is used to turn on and off the fan 3. The battery cell is connected to the output socket. In order to increase the usage scenarios of this embodiment, the output socket includes a bottom socket (not shown in the drawings) and a side socket 9. The bottom socket shell is used to be plugged into an external device, such as Figure 8As shown, the fan is provided with a plug that can be docked, so the bottom socket of the power pack can be directly plugged into the plug to power the fan, realizing the use of a portable fan; and the side socket 9 can be used flexibly, and the device that needs to be powered can be connected to the power cord, and other devices can be powered by the power supply.
