Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of outdoor cabinet with radiator structure.
Background technology
Telecom operators are for adapting to the market demand of city and rural area all standing, rare relatively for personnel, the rural area applied environment that the network capacity demand is little, in order to reduce cost, satisfy the requirement of quickly networking simultaneously, operator is unwilling the higher relatively communications equipment room of construction cost usually and adopts outdoor equipment.And for the city, mainly lead to mend net, at this moment operator also uses outdoor equipment more and more in order to save floor space, and its cost is low and networking is efficient.
In view of these advantages of communication outdoor equipment, outdoor cabinet is used will be more and more widely.According to statistics, outdoor communication equipment has reached 50% in the application percentage of some developed countries; In China, also more and more to the demand of outdoor equipment, for adapting to the needs of communications industry development, the research and development of outdoor cabinet will be one of emphasis of present structural design.
Outdoor equipment is exactly the equipment that can use in outdoor environment.As everyone knows, it is harsh a lot of that outdoor environment is wanted with respect to indoor, and outdoor environment for use requires normally that operating ambient temperature be-40 ℃～+ 50 ℃, and relative humidity is 10%～100%, can adapt to screening rain, snow, sand and dust, robber and various mal-conditions such as rob.
Along with the development of communications industry technology, the integrated level of communication apparatus is more and more higher, and the hear rate of unit space is also increasing, and this makes the heat dissipation problem of equipment become increasingly conspicuous.For outdoor equipment, heat radiation and protection are two distinct issues.Outdoor equipment is distinguished in the protection of equipment self with the maximum of indoor equipment, and different degree of protection is also inequality to the influence of heat dissipation.
The radiating mode of outdoor cabinet mainly contains three kinds: inside and outside ventilation and heat, heat exchanger heat radiation, air-conditioning-type heat radiation.
Inside and outside ventilation and heat, this radiating mode are to force the inner air channel of rack to realize the circulation of inner air and outer air by the fan that is installed in rack inside, thereby the heat of rack internal unit is constantly distributed.The employing of this mode can directly utilize extraneous air, and radiating efficiency is higher, and weight is lighter, and operating cost is low.But shortcoming is that equipment itself need be done " three is anti-" and handle, and rack structure more complicated to the not well protection of the equipment that is installed in rack inside, should accomplish that water proof and dust proof can not make the structure of sealing again.This radiating mode is used for equipment itself and has strong protective capacities, and the good occasion of environment for use.
Air-conditioning-type heat radiation, this radiating mode are to realize the heat radiation of rack internal unit by being installed in air-conditioning on the rack.The advantage of this mode is that the inside and outside environment of rack is isolated, thereby the equipment that is installed in the rack is formed good protection; Secondly, because the refrigeration of air-conditioning makes the rack temperature inside can be lower than ambient temperature, radiating efficiency is very high.But shortcoming also has obviously, at first is exactly the cost height, and the price of air-conditioning is higher than heat exchanger far away, and operating cost is also high at ordinary times, because very power consumption of industrial air-conditioning, this is a long-term expenditure for the operator, and also having one is the maintenance cost height.In above-mentioned three kinds of radiating modes, use the reliability of air-conditioning the poorest, secondly, weight is very heavy.Because the expense of air-conditioning other two kinds of radiating modes relatively is high a lot, so the rack of air-conditioning-type heat radiation is eliminated by operator basically.
Heat exchanger heat radiation, this radiating mode are to realize the conduction of heat inside and outside the rack by being installed in heat exchanger on the rack, thereby the heat of rack internal unit is distributed.The advantage of this mode is that the inside and outside environment of rack is isolated, thereby the equipment that is installed in the rack is formed good protection, and operating cost is low simultaneously.This radiating mode uses in the rack the most extensive at present out of doors.
The heat exchanger of prior art generally includes interior circulating fan, outer circulation blower fan and heat exchanger core body.The volume of heat exchanger is bigger, and the price of this heat exchanger is higher simultaneously, and inconvenience is promoted the use of on the rack out of doors.How designing the airtight heat-exchange system that a kind of volume is thin, cost is lower again, is a technical barrier.
Summary of the invention
The object of the present invention is to provide that a kind of volume is thin, lower-cost outdoor cabinet, to satisfy the requirement of outdoor cabinet to radiator structure.
For this reason, outdoor cabinet provided by the invention comprises: cabinet offers cabinet air outlet and cabinet air inlet in the Width extension of sidewall on its at least one sidewall; And at least one radiator, each radiator comprises housing and the heat exchange core body that is arranged in the housing, housing be flat box-like, have the madial wall that the sidewall with cabinet fits and be positioned at flange around the housing, wherein, circulation air path and outer circulating air duct in heat exchange core body is divided into the housing inner chamber, offer on the housing madial wall in the circulation air inlet and in recycle the air port, be communicated with cabinet air outlet, cabinet air inlet respectively; Offer outer circulation air outlet and external circulation air inlet on the hull outside wall, it is communicated with space outerpace.
In the present invention, the one or more sidewall design of rack are become can carry out the structure of sufficient heat exchange, so just can be under the airtight state of rack heat-exchange capacity by sidewall the heat of rack inside is distributed continuously.In the big heat-sinking capability of needs, apply certain airflow pressure by fan oppose side wall radiator structure and improve heat-sinking capability.And, in the present invention, radiator is become two parts separately with cabinet design, make that the machinability of cabinet and radiator and heat-sinking capability are all better.
When little and rack environment for use temperature was not in the world high temperature area when the inner installed device power of outdoor cabinet, the outer circulation of cooling machine cabinet device realized natural draft according to stack effect, can be without blower fan.In this time, the noise of rack will be very environmental protection, be a silencing equipment.
When big and rack environment for use temperature is in the world high temperature area when the inner installed device power of outdoor cabinet, the rack outer circulation can strengthen the heat exchange efficiency of radiator by the increase blower fan, thereby guarantees the operation reliably and with long-term of outdoor cabinet internal unit.
The outdoor cabinet of conventional heat exchanger is used in contrast, and this sidewall radiator structure has following plurality of advantages:
At first be that heat spreader structures is simple in the present invention, only need shell and heat radiation core body to get final product, cost of manufacture is low.Compare cheap price over half with the conventional heat exchanger of identical performance.
Next is that the fansink designs size of this structure is very flexible, because conventional heat exchanger has comprised blower fan and heat exchange core body, especially the size of blower fan has directly limited the gauge of conventional heat exchanger, and this radiator does not comprise blower fan, even gas-distributing fan also is installed separately, therefore can come the design thickness size according to the needs of rack, make the thin outdoor cabinet of design thickness become possibility.
Be in light weight once more, because size can be done and thin do for a short time, so weight also can decrease.
