[0002] Split generator sets usually refer to generator systems in which the main components of the generator set can be placed or installed separately. Split generator sets adopt modular design, and the generator, control system and other components can be placed in appropriate positions in the distribution box according to actual needs. And it is highly flexible. Due to its split characteristics, this type of generator set is more flexible in spatial layout, especially suitable for occasions with limited space or the need to isolate noise sources. Its split structure makes each part easier to inspect and maintain. When a part has a problem, it can be repaired or replaced separately without affecting the operation of the entire system.

[0024] A forced heat dissipation structure 2 is provided on one side of the box body, and the forced heat dissipation structure 2 forms a partition chamber 3 in the box structure 1. A forced heat dissipation fan 4 is provided in the partition chamber 3. A turbofan is used in this embodiment. The forced heat dissipation fan 4 is driven to rotate by the fan shaft of the generator set, and the rotation of the generator set drives the turbofan to operate, so that there is no need to set a special drive motor, thereby reducing the space occupied by the equipment.

[0025] The forced heat dissipation structure 2 includes a partition plate 5, which is arranged in the box structure 1 and divides the box structure 1 into a partition chamber 3 and a generator set chamber. Relevant equipment of the generator is arranged in the generator set chamber, and the forced heat dissipation structure 2 is arranged in the partition chamber 3.

[0026] Specifically, Figure 3 , 4 As shown, the partition plate 5 is provided with an air inlet 7, and the air inlet 7 is connected to the generator set chamber. When the turbofan is running, its low-pressure side draws hot air in the generator set chamber from the air inlet 7, so that the air flow around the generator set flows to perform forced heat dissipation. The forced heat dissipation structure 2 also includes an outer plate, which is connected to the partition plate 5 to form a partition chamber 3 in the shape of a rectangular box.

[0027] Furthermore, the outer peripheral plate includes a side end plate 8 arranged parallel to the partition plate 5, and a front end plate 9 and a rear end plate 10 arranged perpendicular to the partition plate 5, and an air outlet 11 is provided on the front end plate 9 or the rear end plate 10.

It can be understood that the direction of the opening side of the U-shaped air guide cover 12 in this embodiment is not restricted, so that the direction of the air outlet 11 can be flexibly set, for example, it can be adopted as follows Figure 1 As shown, the air outlet 11 is arranged on the front end plate 9, so that the opening side of the U-shaped plate is within the range of 180° as the heat dissipation side, thereby having a larger air outlet area. In actual use, the opening of the air guide cover 12 can also be oriented in other directions, so that the box structure 1 can be placed in the space according to the position, and the air outlet 11 can be set at the best position, which is flexible.

[0028] Furthermore, an openable inspection cover 13 is provided on the side end plate 8, and after the inspection cover 13 is removed, the interior of the air guide cover 12 is completely open.
