It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] In traditional portable energy storage power supplies, a large independent air duct is set in the portable energy storage power supply, and the heat dissipation fan rotates to discharge the heat of the power heating device from the large independent air duct, so as to achieve the purpose of heat dissipation of the portable energy storage power supply. However, when the portable energy storage power supply is used in an outdoor environment with high humidity or rain, rainwater may enter the portable energy storage power supply through the independent air duct, causing the portable energy storage power supply to short-circuit, affecting the safety of the portable energy storage power supply.

[0050] In order to solve the above technical problems, the utility model proposes the following technical ideas: a guide sealing plate is provided in the portable energy storage power supply, and the electrical part of the portable energy storage power supply is separated from the external environment by the guide sealing plate, so as to avoid the influence of external factors such as rain on the electrical part of the portable energy storage power supply, and enhance the safety of the portable energy storage power supply.

[0066] In summary, the purpose of heat dissipation of portable energy storage power supply can be achieved by conducting the heat of power heating device to semiconductor cooling sheet through flow guide component and dissipating the heat of semiconductor cooling sheet through radiator. The flow guide sealing plate separates the battery pack, power heating device, flow guide component and semiconductor cooling sheet and other electrical components of portable energy storage power supply from the radiator, which can prevent the external environment in contact with the radiator from affecting the electrical components of portable energy storage power supply and enhance the safety of portable energy storage power supply.

[0081] The heat introduction end surface of the heat conducting pipe 7011 is in contact with the heat dissipation surface of the semiconductor cooling plate 50 .

[0082] The heat pipe 7011 receives heat from the semiconductor cooling sheet 50 .

[0083] The heat extraction end surface of the heat pipe 7011 is in contact with and connected to the fin 7012 .

[0084] The heat pipe 7011 can transfer the heat of the semiconductor cooling sheet 50 to the fins 7012 .

[0085] The installation direction of the fin 7012 is consistent with the air flow direction of the fan 702.

[0086] Specifically, the installation direction of the fin 7012 and the installation direction of the fan 702 can both be set to face the heat dissipation port of the portable energy storage power supply.

[0087] The working process of the portable energy storage power supply in this embodiment includes: the heat pipe 7011 conducts the heat of the semiconductor cooling sheet 50 to the fins 7012 , and the fan 702 dissipates the heat of the fins 7012 .

[0092] Specifically, the first fan 7021 and the second fan 7022 may be fixed to two ends of the fin 7012 respectively by riveting or welding.

[0093] Continue to refer Figure 4 The housing 10 of the portable energy storage power supply is provided with a power input port 101 , a power output port 102 and a control panel 103 .

[0105] Among them, each heat pipe is contact-connected.

[0106] Specifically, the heat pipes can be contacted and connected by welding or other methods.

[0111] The working process of the portable energy storage power supply in this embodiment includes: each heat pipe conducts the heat of the power heating device 30 to the semiconductor cooling sheet 50.

[0112] In summary, by conducting the heat of the power heating device to the semiconductor cooling sheet through multiple heat pipes, there is no need to install a separate heat sink for the power heating device, which reduces the cost of the portable energy storage power supply. At the same time, by conducting heat through multiple heat pipes, the semiconductor cooling sheet does not directly contact the power heating device, which can prevent the semiconductor cooling sheet from generating condensed water that affects the power heating device, thereby enhancing the safety of the portable energy storage power supply.
