Due to the distance and wind, the wind becomes hot after the first few groups of modular hardware are cooled. The heat dissipation effect on the modular hardware far away from the heat dissipation structure is not ideal, and each piece of modular hardware cannot be cooled evenly, affecting the working stability of the hardware. Summary of the invention

[0041] The spring column 13 includes a telescopic rod and a spring. The spring is sleeved outside the telescopic rod to prevent the spring from shaking when it is extended and retracted. The rubber pad installed on the side of the clamping plate 24 increases the friction between the clamping plate 24 and the modular hardware, thereby improving the fixing firmness and avoiding damage to the modular hardware.

When the fans A5 and B6 are started, the wind is blown out from the air outlet window 8, and the wind blown out by the fan A5 blows onto the modular hardware on the placement plate 21. At the same time, a part of the wind blown out of the air outlet window 8 enters the air inlet channel 10 through the main air inlet channel 9 opened in the expansion board 1, and the wind enters the channel 22 from the connecting hose 12, and is blown out from the blowing holes 23 opened on the table top of the placement plate 21, so as to blow and dissipate air for each group of modular hardware fixed on the placement plate 21, thereby avoiding the problem that the heat dissipation structure is installed at one end of the expansion board, and the heat dissipation effect of the modular hardware far away from the heat dissipation structure is not ideal, and each piece of modular hardware can be evenly cooled, thereby ensuring the working stability of the hardware.
