detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model comprises a cabinet body 1. A mounting plate 2 is arranged in the cabinet body 1. Mounting seat 5 and a plurality of heat dissipation fans 8, mounting plate 2 is fixed on the mounting seat 5 by mounting bolts 4, the air outlets of a plurality of heat dissipation fans 8 are all facing the back side of the mounting plate 2, and a plurality of heat dissipation fans 8 are all electrically connected to the same On one power management controller 6 , the power management controller 6 is provided with a plurality of fan control buttons 7 , and the plurality of fan control buttons 7 are in one-to-one correspondence with the plurality of cooling fans 8 .

The cooling holes 3 are used to guide the airflow blown out by the cooling fan 8 to the electrical components on the front of the mounting plate 2. The direct air flow is short and can dissipate heat for the electrical components at the first time. Each power management controller 6 is controlled by a separate Button control, can selectively use multiple cooling fans 8, reducing energy consumption.

The diameter of each cooling hole 3 is 1.5 cm, and the density of the cooling holes 3 on the mounting plate 2 is 100 per square decimeter. This structure can meet the heat dissipation requirements of general power distribution cabinets, and a greater density of heat dissipation holes 3 can also be designed according to actual needs.

The mounting base 5 is a rod-shaped structure, and the length of the mounting base 5 is greater than 20cm to ensure that there is sufficient heat dissipation space between the mounting plate 2 and the innermost part of the cabinet body 1, avoiding the situation that heat accumulation cannot be discharged, and is convenient for layout, installation and heat dissipation fan8.

The cabinet body 1 is provided with a plurality of air-introducing holes, which are arranged on the back of the cabinet body 1 and communicate with the inside of the cabinet body 1 , and the plurality of air-introducing holes correspond to the plurality of cooling fans 8 one by one.

The back of the cabinet body 1 is provided with a power management controller 6 and a wire hole 9, the wire hole 9 communicates with the inside of the cabinet body 1, and the control cables of a plurality of cooling fans 8 pass through the wire hole 9 and are connected to the power management controller. 6 electrical connections.

The heat dissipation principle of the high-efficiency heat dissipation power distribution cabinet of the utility model is as follows:

After the electrical components are installed on the mounting plate 2 and the power distribution cabinet is assembled, the power distribution cabinet can be used. The installation position of cooling fan 8 is determined according to the installation position of electrical components. When the power distribution cabinet is in use, if the number of working electrical components is small, the heat generated will be less. At this time, only the cooling fan 8 on the back of the corresponding electrical component can be powered on, and the working components The electrical components dissipate heat, which not only has high heat dissipation efficiency, but also saves energy. If there are many electrical components at work, the heat generated will be more. At this time, all cooling fans 8 can be selectively powered on.
