[0028] The utility model provides a portable outdoor power supply.

[0029] like Figures 1 to 4 As shown, in one embodiment of the present invention, a portable outdoor power supply includes an outer shell 100, a cover 200, a battery cell 300, an inverter 400, a fan 500, a PCBA board 600, a display assembly, and a thermally conductive metal sheet 800. In this embodiment, the cover 200 specifically includes a handle 210, which is disposed on the top surface of the cover 200 and is connected to the outer shell 100. Specifically, the interior of the outer shell 100 is provided with vertical partitions 130, horizontal partitions 140, and a plurality of protruding strips 150. There are two vertical partitions 130, and three installation spaces are formed between the inner wall of the outer shell 100 and the two vertical partitions 130. The aforementioned PCBA board 600 is disposed in the first installation space. The PCBA board 600 is provided with multiple charging and discharging ports, which extend through the outer shell 100 to facilitate user charging and discharging operations. The inverter 400 and the fan 500 are installed in the second installation space, and the fan 500 is located on the side of the second installation space away from the charge and discharge interface. The battery cell 300 is installed in the third installation space.

[0030] Furthermore, the battery cells 300, inverter 400, and PCBA board 600 are all mounted on the transverse partition 140, and a ventilation channel is formed between the bottom wall of the outer shell 100 and the transverse partition 140 below the third mounting space. The height of the ventilation channel ranges from 0.1 cm to 1 cm, and the thickness of the thermally conductive metal sheet 800 ranges from 0.02 cm to 0.1 cm. The relatively small height of the ventilation channel helps reduce the cross-sectional area of ​​airflow after entering the ventilation channel, thereby increasing the airflow velocity and improving heat dissipation efficiency. Furthermore, the ridges 150 include abutting curved surfaces, and a plurality of ridges 150 are spaced apart on the inner wall of the outer shell 100. The side surfaces of the battery cells 300, inverter 400, PCBA board 600, and fan 500 can abut against the abutting curved surfaces.

[0031] In this embodiment, the thermally conductive metal sheet 800 is specifically U-shaped and includes vertical segments on both sides and a transverse segment in the middle. Specifically, the vertical segment is disposed in the gap between the inner wall of the outer shell 100 and the battery cells 300, inverter 400, and PCBA board 600, and is located between adjacent ridges 150. The bottom of the vertical segment passes through the transverse partition 140 and extends into the ventilation channel, while the transverse segment of the thermally conductive metal sheet 800 is located within the ventilation channel. Furthermore, the transverse segment of the thermally conductive metal sheet 800 is composed of two pieces, and there is a gap between the bottom surface of the transverse partition 140, the two transverse segments, and the bottom wall of the outer shell 100. Airflow can flow through the gap, thereby removing heat from the transverse segments of the thermally conductive metal sheet 800, while heat from the vertical segments of the thermally conductive metal sheet 800 is continuously transferred to the transverse segments.

[0032] like Figure 1 、 2 As shown in FIG3 , the outer shell 100 further includes an air inlet grille 110 and an air outlet grille 120. The fan 500 described above includes a mounting housing and an impeller. The impeller is mounted within the mounting housing. The front end of the mounting housing communicates with the air inlet grille 110, the rear end of the mounting housing communicates with the input end of the ventilation channel, and the output end of the ventilation channel communicates with the air outlet grille 120. Specifically, the mounting housing includes a first section, a second section, and an air outlet 510. The vertical cross-section of the first section is square, and the impeller is disposed in the middle of the first section. The vertical cross-section of the second section is triangular, and the air outlet 510 is disposed at the bottom of the second section and communicates with the input end of the ventilation channel.

[0033] In this embodiment, the display assembly specifically includes a display PCB and a display screen 700. The display PCB is disposed above the fan 500, and the display screen 700 is disposed on the cover 200. The display assembly is configured to display the charge and discharge status and parameters of the outdoor power supply, thereby enabling the user to intuitively understand the charge and discharge process and status of the outdoor power supply.

[0034] Specifically, the working principle and process of the utility model are as follows:

[0035] By installing a fan, a heat-conducting metal sheet, and a ventilation channel, the fan blows air to dissipate heat from the metal heat-conducting sheet. The metal heat-conducting sheet then transfers heat from the installation space to the horizontal section of the ventilation channel through the vertical section for heat dissipation. This eliminates the need for a large ventilation space within the outdoor power supply, reducing its size and making it easier for users to carry around. Furthermore, the smaller ventilation channel increases the airflow rate, thereby improving heat dissipation efficiency.

[0036] When in use, the outside air can be sucked in from the air inlet grille by the fan, and the air is input into the ventilation channel from the first section, the second section and the air outlet of the installation shell, and then discharged from the exhaust grille at the rear end of the ventilation channel, thereby achieving a heat dissipation effect.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
