Preferred embodiments of the present invention are described below with reference to the accompanying drawings:
with reference to fig. 1 and 4, in this embodiment, the fan control device is used for dissipating heat of a heating component in the cabinet, in this embodiment, an internal space of the cabinet 1 is divided into an upper chamber 11 and a lower chamber 12, according to a difference in heat generation amount, the heating component in the cabinet 1 is divided into a magnetic component 124 with a large heat generation amount and a heat-prone component 111 except for the magnetic component 124, the heat-prone component 111 and a second fan component 112 for dissipating heat of the heat-prone component 111 are disposed in the upper chamber 11, and the magnetic component 124 and a first fan component 125 for dissipating heat of the magnetic component 124 are disposed in the lower chamber 12; through setting up division board 123, divide into first cavity 121 and second cavity 122 with lower cavity 12 that magnetic component 124 was located, magnetic component 124 passes through perpendicularly and sets up in first cavity 121 and second cavity 122, and magnetic component 124 periphery and division board 123 close coupling, first fan subassembly 125 installs in first cavity 121, is equipped with the first wind channel 13 that is used for the ventilation between upper chamber 11 and lower cavity 12.
The internal space of the cabinet 1 is divided into an upper chamber 11 and a lower chamber 12, and after the air enters the lower chamber 12 through the divided two chambers, all cold air enters the upper chamber 11 through the gap inside the magnetic component 124, so that the optimal heat dissipation effect is achieved.
The partition plate 123 in the lower chamber 12 divides the lower chamber 12 where the magnetic component 124 is located into the first chamber 121 and the second chamber 122, the periphery of the magnetic component 124 is tightly combined with the partition plate 123, and when the first fan assembly 125 works normally, cold air enters from the first chamber 121, enters into the second chamber 122 through a gap inside the magnetic component 124, and enters into the upper chamber 11 through the first air duct 13. Because the inside of the magnetic component 124 is the place with the largest heat generation amount, the arrangement of the partition plate 123 enables the cold air entering the first fan assembly 125 to gather in the space of the first cavity 121, and because the surrounding space is blocked by the partition plate 123, the cold air can only flow through the gap inside the magnetic component 124 and enter the second cavity 122 on the upper portion of the partition plate 123, so that the air path between the first cavity 121 and the second cavity 122 is only inside the magnetic component 124, thereby preventing the air from flowing away from the periphery of the magnetic component 124, and enabling the heat dissipation effect on the magnetic component 124 to be better. If the partition plate 123 is not arranged, the wind resistance of the gap inside the magnetic component 124 is larger than the wind resistance outside the magnetic component 124, and cold air hardly passes through the gap between the magnetic component 124, so that more heat can be dissipated to the surface of the magnetic component 124, and the heat generated inside is not well dissipated, so that the heat dissipation effect is poor, and the risk of overheating and damage exists.
The fan control apparatus of the above embodiment further includes a detection unit for determining whether the first fan assembly 125 fails, and a processing unit for powering off the first fan assembly 125 when the first fan assembly 125 fails, where the detection unit and the processing unit (not shown in the figure) are both disposed inside the cabinet.
As shown in fig. 1, 2, and 4, when the first fan assembly 125 for dissipating heat from the magnetic component 124 normally operates, the wind flowing through the magnetic component 124 is discharged out of the cabinet 1 through the first wind duct 13.
As shown in fig. 1, 3, and 5, when the detection unit detects that the first fan assembly 125 has a fault, the processing unit immediately powers off the first fan assembly 125, at this time, the air pressure in the lower chamber 12 where the magnetic component 124 is located becomes small, the air pressure in the upper chamber 11 where the second fan assembly 112 normally operates becomes larger than that in the lower chamber 12, and an air pressure difference occurs between the upper chamber 11 and the lower chamber 12, so that the cold air of the second fan assembly 112 normally operates flows in two paths, one path normally dissipates the heat of the thermal components 111 except the magnetic component 124, and the other path reversely flows through the first air duct 13 and passes through the magnetic component 124, so that the normal heat dissipation of the magnetic component 124 can be ensured, and the dissipated hot air flows out from the gap between the first fan assemblies 125 which are powered off. Therefore, the magnetic component 124 which mainly generates heat is protected from being damaged, the whole cabinet does not need to be powered off, and the reliability of the cabinet is greatly improved.
Optionally, in an embodiment, a reverse fan may be disposed at a position adjacent to the first fan assembly 125, or at a position corresponding to the first air duct 13, and when the detection unit detects that the first fan assembly 125 fails, the processing unit immediately powers off the first fan assembly 125 and simultaneously starts the reverse fan, where the reverse fan functions to facilitate introducing cold air from the second fan assembly 112 in the upper chamber 11 into the lower chamber 12 to dissipate heat of the magnetic component 124. The number of the reverse fans may be set to at least one, and is not limited herein.

Wherein, the wind part output by the target fan during operation reversely flows through the magnetic component 124; the failure fan means that the fan has the conditions of insufficient rotating speed, overlarge rotating speed, failure shutdown, unstable rotating speed and the like.

As shown in fig. 6, in this embodiment, the fan control method using any one of the fan control devices includes the following steps:

step 1031: collecting the real-time temperature of the magnetic component 124;
specifically, the temperature collector collects the temperature of the magnetic component 124 once at preset time intervals, and generally speaking, the higher the temperature of the magnetic component 124 is, the greater the number of the failed fans in the first fan assembly 125 is.
Step 1032: determining the target rotating speed of the target fan based on the real-time temperature of the magnetic component 124 and preset temperature and rotating speed corresponding information;
