Detailed Description

Referring to fig. 1, a take core switch of UPS, which comprises a housin 1, mainboard module 7, interface module 6 and UPS power module 8, from up having set gradually first rack 2 down in casing 1, second rack 3, third rack 4 and fourth rack 5, four rack intervals set up, the side of rack is connected fixedly with the roof of casing 1, first rack 2 leaves the interval with the top surface of casing 1, top surface at first rack 2 is fixed with three group's extraction fan 9, interface module 6 fixes the top surface at second rack 3, mainboard module 7 fixes the top surface at third rack 4, UPS power module 8 fixes the top surface at fourth rack 5, air exit 10 has been seted up symmetrically on the lateral wall on the upper portion of casing 1, install exhaust fan 11 in air exit 10 department.

The working principle of the core switch is as follows: when the switch is powered on to work, each fan is also powered on to start running, the power module, the mainboard module 7 and the UPS module 8 generate heat in the working process, so that the temperature in the shell 1 rises, the external cold air is sent into the shell 1 by the exhaust fan 9, meanwhile, the hot air in the shell 1 is extracted by the exhaust fan 11, and the hot air is discharged from the exhaust outlet 10, and the cycle is repeated. Because the interval is great between each module, therefore the heat that the module produced can give off to casing 1 in fast, and because the hot-air in casing 1 is the upflow, the air cycle direction in the casing 1 is also ascending, so the heat in casing 1 can be taken away fast, guarantees good thermal diffusivity, realizes the rapid cooling to with the core switch.

In this embodiment, the reason why the UPS power module 8 is disposed above the motherboard module 7 and the motherboard module 7 is disposed above the interface module 6 is that in the actual working process, the heat generated by the UPS power module 8 is larger than the heat generated by the motherboard module 7, the heat generated by the motherboard module 7 is much larger than the heat generated by the interface module 6, and the hot air with heat in the housing 1 flows upward. Therefore, the module with less heat generation is placed below the module with more heat generation, the heating of the hot air below to the module above can be reduced as much as possible, and the hotter module is ensured to radiate heat more smoothly.

As shown in fig. 1, a first blowing fan 12 for blowing air upward is fixed to the bottom surface of the third rack 4, and the first blowing fan 12 is located directly below the main board module 7. The first blowing fan 12 can blow air to the bottom surface of the main board module 7, so that the air flow at the bottom surface of the main board module 7 is accelerated, and the main board is cooled more quickly.

On this basis, leave the interval between the top surface of mainboard module 7 and third rack 4, mainboard module 7 is connected fixedly through spliced pole 16 and third rack 4. Therefore, the heat dissipation space on the bottom surface of the main board module 7 is larger, and the heat dissipation of the main board module 7 is more facilitated.

Similarly, in order to accelerate the heat dissipation of the UPS power module 8, a second blowing fan 13 for blowing air upward is also attached to the bottom surface of the fourth rack 5 in the present embodiment.

In this embodiment, a V-shaped flow guide surface 14 is further disposed on the inner top wall of the casing 1, two side edges of the flow guide surface 14 are respectively located on the surfaces where the two air outlets 10 are located, and the side edge of the flow guide surface 14 is higher than the air outlets 10. Because the diversion surface 14 is in a V shape, when the hot air in the casing 1 flows upwards and meets the diversion surface 14, the diversion surface 14 guides the hot air to the air outlet 10 on the side surface of the casing 1, which is beneficial to discharging the hot air more quickly, thereby improving the heat dissipation effect. In this embodiment, the included angle of the "V" shaped flow guide surface 14 is 150 °, and in other embodiments, the included angle may be 155 °, 160 °, or other angles.

In order to further improve the heat dissipation effect, heat dissipation fins 15 are attached to the surfaces of the UPS power module 8 and the motherboard module 7, and the heat dissipation fins 15 increase the heat dissipation area of the motherboard module 7 and the UPS power module 8, so that heat generated by the motherboard module 7 and the UPS power module 8 is dissipated more quickly.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
