The main housing 1 has multiple grooves 11 on its side, and each groove 11 is equipped with a heat dissipation component 3, which is a fan assembly. The grooves 11 can act as air ducts for the fan assembly to improve the cooling effect. A water baffle 4 is provided on the outside of the heat dissipation component 3. The water baffle 4 is composed of multiple downward-sloping blades with the inclined surface facing the outside of the grooves 11, which can prevent water from splashing into the interior of the main housing 1, achieving an IPX4 waterproof rating. The surface of the water baffle 4 has multiple openings 41, which allow airflow to pass through normally while providing waterproofing. The surface of the grooves 11 has multiple vents 111, which are arranged along the fan blades of the fan assembly to ensure ventilation and prevent the fan assembly from blowing impurities into the interior of the main housing 1. The vents 111 and the openings 41 are connected. By placing the heat dissipation component 3 in the groove 11, dust or water can be prevented from falling into the main box 1. The groove 11 can also act as an air duct to improve the heat dissipation effect of the heat dissipation component 3. The groove 11 can also serve as a handle to make it easy for users to move the main box 1. A water baffle 4 is provided on the outside of the heat dissipation component 3 to prevent water from splashing onto the heat dissipation component 3 and into the main box 1. This three-in-one design realizes the functions of air duct heat dissipation, IPX4 waterproofing and transportation. Furthermore, assembling the fan and the handle together facilitates later maintenance, such as cleaning dust and replacing the fan.

[0035] In this embodiment, two grooves 11 are arranged opposite to each other on the side of the main housing 1. The fan assembly on one side blows outside air into the main housing 1, and the fan assembly on the other side blows the air out of the main housing 1, thereby realizing the airflow of the main housing 1.

[0036] In this embodiment, the water-blocking component 4 is a louver, which has the functions of ventilation and preventing water splashing.

[0037] In this embodiment, a mounting member 5 is also provided on the outer side of the heat dissipation component 3. The mounting member 5 matches the groove 11, and the water-blocking member 4 is installed between the mounting member 5 and the heat dissipation component 3. The mounting member 5 is a sleeve structure, which can fit well with the side wall of the groove 11 and connect to the outer side of the main box 1. One end of the mounting member 5 presses the water-blocking member 4 and the heat dissipation component 3 into the groove 11, thereby fixing the water-blocking member 4 and the heat dissipation component 3.

[0038] In this embodiment, a filter plate 6 is provided between the heat dissipation assembly 3 and the water baffle 4. The surface of the filter plate 6 has multiple filter holes corresponding to the fan assembly, which ensures ventilation while preventing impurities from being blown into the main housing 1.
