It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Please see Figure 1-2 This utility model provides a technical solution for the overall heat dissipation structure of a hybrid electric generator: The overall heat dissipation structure of a hybrid electric generator includes a whole housing 1, the inside of the whole housing 1 is a cavity, an engine 2 is installed in the cavity, a battery 3 is installed on the outside of the whole housing 1 located in the cavity, a power fan 4 is installed on one side of the engine 2, a battery bracket 6 is installed on one side of the battery 3, and a battery waterproof cover 7 is detachably installed on the top of the battery bracket 6.

[0024] In this embodiment, by installing the battery 3 on the outside of the housing 1, the battery is located at the front of the machine, making the lifting weight distribution more balanced. The battery area and the engine area are independent. The battery can be detached and installed through the battery bracket 6 and the battery waterproof cover 7, allowing the battery 3 to be disassembled in a modular manner, which is convenient for later maintenance. The battery 3 shares an air duct with the air intake of the engine 2 and the heat dissipation of the control module 5, which solves the problem of the battery not being able to be forcibly cooled, making the device safer and more reliable to use.

[0025] Furthermore, the control module 5 is installed on the side of the main housing 1 that is opposite to the engine 2 and located on the side of the power fan 4.

[0026] In this embodiment, a control module 5 is provided to control the normal operation of the device. The control module 5 is installed in the heat dissipation duct of the whole machine to facilitate heat dissipation of the control module 5.

[0027] Typically, the battery holder 6 has a holder air inlet grille 8.

[0028] In this embodiment, by providing a bracket air inlet grille 8 on the battery bracket 6, it is convenient to allow air to enter the equipment through the bracket air inlet grille 8.

[0029] Specifically, the outer casing 1 has an air intake grille 9 on one side wall of the battery 3.

[0030] In this embodiment, the air inlet grille 9 of the whole machine casing is provided to facilitate air intake into the internal cavity of the whole machine casing 1.

[0031] In addition, the battery bracket 6 is provided with a guide groove 10, which is compatible with the battery waterproof cover 7.

[0032] In this embodiment, the guide groove 10 facilitates the installation of the upper battery waterproof cover 7 on the battery bracket 6. The battery bracket 6 and the battery waterproof cover 7 are installed on the outside of the battery 3, and together with the machine housing 1, the battery 3 is enclosed in the cavity. By installing the battery 3 on the outside of the machine housing 1, the battery area and the engine area are independent.

After the generator 2 starts, it drives the power fan 4 to rotate and draw in air. The air enters through the bracket air inlet grille 8, surrounds the battery 3, and dissipates heat from the battery 3. Then, the air enters the cavity through the housing air inlet grille 9 on one side to dissipate heat from the control module 5 and the engine 2. Finally, the air is discharged through the exhaust grille 12. The battery 3 shares the same air intake with the engine 2 and the control module 5 for heat dissipation, which solves the problem of the battery not being able to be forcibly cooled, making the device safer and more reliable to use.
