The invention provides a power supply module and a multi-power system. The power supply module comprises a fan assembly, an air channel cover plate, a first support plate, a second support plate and at least one board level assembly. Compared with the prior art, the power supply module utilizes the air channel cover plate and the first support plate, the second support plate and the board level assembly to form a first air channel and a second air channel, which are communicated with each other; the fan assembly arranged at the lower end of the second air channel blows outside air into the first air channel and the second air channel, and takes a part of heat of the board level assembly out of the power supply module to dissipate heat for the power supply module; and in addition, when thefan assembly blows the outside air into the first air channel and the second air channel, air flow in the first air channel and the second air channel is accelerated and the first air channel and thesecond air channel realize convection with the outside world through a gap around the board level assembly, so that the heat accumulated around the board level assembly is taken out of the power supply module through the first air channel and the second air channel, and the power supply module is further cooled.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a power supply module and a multi-power supply system. Background technique [0002] At present, multiple power supply modules are connected in series to form a multi-power supply system, which can output higher voltage and greater power to meet the power supply requirements of more devices. [0003] Usually, the power module is provided with a fan assembly, which transfers the heat inside the power module to the outside of the power module through convection, so as to ensure that the temperature of the power module is within an allowable range. [0004] However, due to the internal layout of the power module in the prior art, the board-level components inside the power module will generate heat accumulation during the working process, resulting in a high temperature, and corresponding fans must be installed for each board-level component. components, in order to reduc...
