Communication cabinet heat radiation VMCTechnical field
The utility model relates to a kind of communication cabinet cooling system, relates in particular to a kind of communication cabinet heat radiation VMC.
Background technology
Along with communication, technological development, the data center of electronics integrated monitoring are obtained employing widely, and rack becomes the elementary cell and the carrier of these data centers, server undoubtedly.Usually in the room of the independent sealing of data center, be provided with many rack, in every rack a large amount of electric equipments and element be installed, for example common printed circuit board (PCB), through to its compact and orderly arrangement and input current to realize function corresponding.Data show the about 10A of input current of every rack, and sizable part of these electric currents all is converted into heat and discharges.Electric elements around these d/d heats will react to; Influence its operate as normal; Thereby need in time discharge rack; And provide cold air in order to compensation, for the machine room data center that has a plurality of racks, also need keep the preference temperature in whole room equally, and guarantee the preference temperature that each rack is local.
And the outdoor communication cabinet that moves at present is to adopt split cabinet (equipment compartment, battery flat split) form basically, is divided into top and the bottom, and is up and down two enclosure spaces.Top equipment compartment fan heat radiation form, lower part battery flat natural heat dissipation.Demand in the present society, rack all is 24 hours the work of not shutting down, the hot machine of multimachine has backup simultaneously.All make the heat of discharge of rack significantly increase, especially under the situation of summer high temperature, the cooling system in the rack almost loses function, can not guarantee that equipment is stable, safe operation, becomes operator and is badly in need of the difficult problem that solves.
Summary of the invention
The utility model provides a kind of communication cabinet heat radiation VMC to the defective of the cooling system of prior art rack, and so-called VMC is by blower fan, and air inlet, exhaust outlet are formed, thereby the mode of carrying out air draught and air-supply reduces temperature.Can reach not only that dustproof, quiet, good cooling effect, life-span are long, the effect of sustainable work, and operator need not increase too big input, not influence normal communication.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Communication cabinet heat radiation VMC; Comprise rack body, last ventilating opening, following ventilating opening and cabinet base; Last ventilating opening is an air intlet, and following ventilating opening is an air outlet slit, thereby is that air flow exchanges the temperature that reduces rack with outside air through last ventilating opening and following ventilating opening.
As preferably; Last ventilating opening comprises rain cover, goes up anti-dust filter mesh and axial flow air intake machine; Last rain cover is connected with the outside of last anti-dust filter mesh, and the inboard of last anti-dust filter mesh is connected with the axial flow air inlet, and following ventilating opening comprises rain cover, following anti-dust filter mesh and axial flow exhaust blower down; Following rain cover is connected with the outside of following anti-dust filter mesh, and the inboard of following anti-dust filter mesh is connected with the axial flow exhaust outlet.Rack is accomplished the circulation with outside air through the axial flow air intake machine of last ventilating opening and the axial flow exhaust blower of following ventilating opening; Two ventilation orifices all have anti-dust filter mesh up and down, have the function that prevents that worm and decayed tooth class animal from invading, and are convenient to cleaning and keep, change; Ventilating opening all is equipped with rain cover up and down, can adapt to extraneous environment.
As preferably, the rack body interior is equipped with temperature control system and temperature sensor.When the inner device temperature of rack raises; Start axial flow air intake machine and axial flow exhaust blower in the temperature control system that is connected with temperature sensor; Thereby the temperature of equipment in the reduction rack; When temperature dropped to suitable temperature, under the control of temperature control system, axial flow air intake machine and axial flow exhaust blower quit work.Like this can better controlled the temperature of equipment in the rack, can increase useful life of equipment, equipment can continuous firing, and can reach the effect of energy savings.

Fig. 1 is the structure chart of facing of the utility model;
Fig. 2 is the structure chart of upper and lower anti-dust filter mesh.
Embodiment
Below in conjunction with attaching Fig. 1 and 2 and embodiment describes in further detail the utility model.
Embodiment
Communication cabinet heat radiation VMC comprises rack body 32, last ventilating opening 24, following ventilating opening 25 and cabinet base 31, and last ventilating opening 24 is an air intlet, and following ventilating opening 25 is an air outlet slit.
Last ventilating opening 24 comprises rain cover 7, goes up anti-dust filter mesh 6 and axial flow air intake machine 5; Last rain cover 7 is connected with the outside of last anti-dust filter mesh 6; The inboard of last anti-dust filter mesh 6 is connected with axial flow air inlet 5; Following ventilating opening 25 comprises rain cover 8, following anti-dust filter mesh 9 and axial flow exhaust blower 10 down, and following rain cover 8 is connected with the outside of following anti-dust filter mesh 9, and the inboard of following anti-dust filter mesh 9 is connected with axial flow exhaust outlet 10.
Rack body 32 inside are equipped with temperature control system 22 and are connected with temperature sensor 21 and through lead 23.
The equipment operation of working for a long time in rack, the electric current that passes through can produce great amount of heat, causes that temperature constantly raises in the rack, the room temperature but temperature is above standard, temperature sensor 21 passes to temperature control system 22 with signal through lead 23.At this moment, the axial flow air intake machine 5 of ventilating opening 24 and the axial flow exhaust blower of following ventilating opening 25 are gone up in temperature control system 22 startups, and air in the rack and outside air circulation utilize fresh wind to carry out thermal energy exchange, thereby reach cool effect.In the time of work, anti-dust filter mesh 6 also prevents the function that worm and decayed tooth class animal are invaded simultaneously, is convenient to cleaning and keeps, changes.Reach after the transformation, dustproof, quiet, good cooling effect, life-span are long, but continuous operation.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
