Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 shows the structure of such a central-positioned switch cabinet, and several embodiments are listed below with reference to the figures.
Example 1:
a central switch cabinet comprises a central cabinet 1, wherein a placing frame 2 is arranged from top to bottom on the central cabinet 1, and components are placed on the placing frame 2; the utility model discloses a side cabinet, including well cabinet 1, baffle 4, air inlet 6, every exhaust vent 6 wears out from 3 tops of cabinet on the limit through the pipeline in the cabinet 3, air inlet 5 department is provided with fan 7 towards well cabinet 1 in the cabinet 3 of limit in 1 both sides of well cabinet, separates by baffle 4 between limit cabinet 3 and the well cabinet 1, baffle 4 sets up air inlet 5 in the lower part of the department that corresponds between adjacent rack 2, baffle 4 corresponds the upper portion of department between adjacent rack 2.
Fan 7 work, ventilate the input cold air in 1 from well cabinet 1 both sides to well cabinet through fresh air inlet 5, back between the cold air entering adjacent rack 2, absorb the heat that components and parts distribute in this space, the air is heated the come-up on the one hand, and on the other hand is under the condition of the continuous air inlet of fresh air inlet 5, and hot-blast from exhaust vent 6 discharges, gets into the pipeline in the side cabinet 3, again by discharging from 3 tops on the side cabinet. In this process, the heat between each layer rack 2 is all taken away fast, each other does not influence, and therefore cooling efficiency is secure, and hot gas is upwards discharged from side cabinet 3 by the pipeline simultaneously, avoids hot gas to conduct heat to well cabinet 1 once more.
Example 2:
on the basis of the embodiment 1, it is further defined that in the middle cabinet 1, a guide plate 8 is arranged on the partition plate 4 between the air inlet 5 and the air outlet 6. The air is guided to flow direction after entering the middle cabinet 1, the contact area between the air and the components is increased as much as possible and then the air is discharged, and heat is fully taken away.
Example 3:
on the basis of embodiment 1, it is further limited that the guide plate 8 extends obliquely downward toward the inside of the middle cabinet 1. Guide board 8 causes cold wind to get into 1 in-process of well cabinet on the one hand, and the space volume reduces, and pressure increase can increase wind-force, increases the air stroke, fully cools off the components and parts at well cabinet 1 middle part, and on the other hand forces the components and parts full contact of cold wind to the below, and the heat absorption effect is better.
Example 4:
on the basis of embodiment 1, further inject the fresh air inlet 5 on be provided with filter screen 9, filter the air inlet, protect components and parts.
Example 5:
on the basis of embodiment 2, further inject well cabinet 1 in, the middle part between the adjacent rack 2 is provided with backward flow board 10, backward flow board 10 is the U type, and its open end is towards fresh air inlet 5 and exhaust vent 6. The return plate 10 also plays a good guiding role, and prevents the air flow from being disordered and the hot air from not being dissipated due to the mutual collision of the air inlets at the two sides of the middle cabinet 1.
The most preferred embodiment is as follows:
further inject on embodiment 1's basis, the pipeline from 3 tops of limit cabinets break out, 3 outer walls of limit cabinets set up apron 11, apron 11 size is greater than the size of breaking out, apron 11 is connected with 3 outer walls of limit cabinets, and leaves the clearance between apron 11 and the 3 outer walls of limit cabinets. The cover plate 11 plays a role in shielding and protecting the penetrating position of the pipeline from the top of the side cabinet 3, prevents dust from entering and can smoothly exhaust through the gap.
