The most important component on the motherboard is the chipset, which is usually composed of a north bridge and a south bridge. Some chipsets are designed with a single-chip microcomputer to enhance their performance. These chipsets provide a common platform for the motherboard to connect different devices and control the communication between different devices.

[0003] According to the needs of production and processing, the existing main control board has also become adjustable. The adjustable main control board is generally used in robots, solar inverters, optical instruments, audio and lighting equipment, etc. During the use of related equipment, the main control board will inevitably heat up, and as the operating time of the equipment increases, the heating of the main control board will become more and more obvious, which is easy to cause damage to the main control board to a certain extent. In order to make the main control board work better, a plurality of heat sinks for enhancing heat dissipation are generally provided on the main control board. Through the fan installed on the inside of the equipment, the wind blown by the fan blows through the heat sink fins in parallel, which speeds up the gas flow in the equipment, thereby facilitating the removal of heat from the heat sink fins and speeding up the heat dissipation effect of the heat sink fins. However, during long-term use of the existing adjustable main control board, more dust is easily attached to the outer surface of the heat sink fins, which affects the heat dissipation of the heat sink fins to a certain extent.

[0004] Therefore, it is necessary to provide a new adjustable main control board to solve the above technical problems. Utility Model Content

[0012] Compared with the related art, the adjustable main control board provided by the utility model has the following beneficial effects:

[0013] The gas blown out by the fan in the device enters the gap between the plurality of second heat dissipation fins. After the gas passes through the inclined guide plate, part of the gas moves along the inclined direction of the guide plate and is blown out obliquely. The gas moving along the inclined direction of the guide plate acts on the first heat dissipation fin. Due to the certain angle between the gas and the first heat dissipation fin at this time, compared with the gas moving parallel, the obliquely moving gas can hit the first heat dissipation fin. On the one hand, the air flow attached to the first heat dissipation fin is accelerated to drive the heat. On the other hand, the impact caused by the gas also facilitates the removal of the gas attached to the first heat dissipation fin. Dust is taken away, which is convenient for cleaning the outer surface of the first heat dissipation fin. To a certain extent, the heat dissipation effect of the first heat dissipation fin is enhanced. In addition, the top and bottom of the guide plate are respectively an upward inclined surface and a downward inclined surface.

At this time, the gas that moves out obliquely above and below the guide plate hits the second heat dissipation fin above the guide plate and the second heat dissipation fin below the guide plate respectively, which is convenient for taking away the heat and dust on the second heat dissipation fin.

The gas enters the gap between the plurality of second heat dissipating fins 4. After the gas passes through the inclined guide plate 6, part of the gas moves along the inclined direction of the guide plate 6 and is blown out obliquely. Part of the gas moves out from the inclined surfaces at the top and bottom of the guide plate 6 and moves along the inclined surfaces at the top and bottom of the guide plate 6.
