Description
Technical field
The utility model relates to communication cabinet, more particularly, relates to the communication cabinet of being with side heat exchanger.
Background technology
The communication cabinet major part that existing market is used all is equipped with heat-exchanger rig, can be divided into heat exchanger overhead type rack, heat exchanger bottom type rack, the side-mounted rack of heat exchanger and heat exchanger door dress formula rack according to the position difference of its placement.As shown in Figure 5, heat exchange core 100 generally includes interior circulation air path and outer circulating air duct quadrature, alternately isolated arrangement.Interior circulation air path is introduced the hot-air of main equipment, and outer circulating air duct is introduced extraneous cold air, and both carry out heat exchange, thereby reach the purpose of rack equipment cooling.
In the existing market in all heat exchanger 204 side-mounted communication cabinets, comprise in 204 dresses of heat exchanger formula rack, circulation air path generally adopts cyclic design up and down in it, the interior circulation air path that is heat exchanger 204 vertically is provided with, its air inlet 201 is arranged on certain part of rack top, and air outlet 202 is arranged on certain part of rack below.During work, the heat that main equipment 203 produces is got rid of from the back of main equipment 203, the fan that Hot air quilt is positioned on heat exchanger 204 circulation air paths sucks, enter the heat exchanger 204 in heat exchanger storehouse 205 from the air inlet 201 of interior circulation air path, and carry out heat exchange with cold air in the outer circulating air duct, air through cooling off is through the air outlet 202 Returning equipment storehouses 206 of interior circulation air path, thus arrival heat radiation purpose.Yet, since at present main equipment 203 in the equipment compartment 206 normally layering in vertical direction install, so it is many that the cold blast rate that the main equipment 203 (for example main equipment of bottom) at air outlet 202 places of close interior circulation air path obtains must obtain than the main equipment 203 (for example main equipment on top) away from air outlet 202, caused the heat exchange of the main equipment 203 in the equipment compartment 206 inhomogeneous.In addition, as shown in Figure 4, in the heat exchanger 204 side-mounted communication cabinets, the air outlet 202 of interior circulation air path often faces the sidewall of the mounting structure of the sidewall of main equipment 203 or main equipment 203, and often needing to enter main equipment 203 from the front of main equipment 203, cools off in cold wind, the feasible like this cold wind that comes out from the air outlet 202 of interior circulation air path need turn round and could arrive the front of main equipment 203, has reduced heat exchange efficiency.
Along with the operating power of equipment in the modern communication rack is increasing, especially heat exchanger is put in the formula communication cabinet, and the heat exchange coefficient of its heat exchanger requires increasing, causes heat exchanger volume and weight also increasing like this.Usually the weight of heat exchanger all reaches more than 70 kilograms, and is very difficult when installation and removal.In case the most fearful is that heat exchanger breaks down, the heat-exchange system of whole communication cabinet is in paralysis, makes that the equipment in the equipment compartment can't effectively be cooled off, and the harm to communication apparatus is very big like this.
In addition, all are equipped with in the communication cabinet of heat exchanger in the existing market, circulating fan all is positioned at the air inlet of heat exchanger circulation air path in it, the air that the circulation air inlet is advanced in the heat exchanger is the heat that the rack main equipment is discharged, general temperature reaches more than 75 ℃, and fan is positioned at performance and the life-span that work under the high temperature can influence fan for a long time; In addition, the outer circulation fan of rack all is positioned at the air inlet of heat exchanger outer circulation, what the heat exchanger external circulation air inlet was advanced is outside air, under the harsh climate condition, as rain, sandstorm etc., fan can suck rainwater or sand and dust unavoidably, fan damaged, thus the useful life of shortening fan.
The utility model content
The technical problems to be solved in the utility model is, the defective at the side-mounted communication cabinet of above-mentioned heat exchanger of prior art provides the heat exchanger that a kind of heat exchange is even, heat exchange efficiency is high, the rack heat-exchange system is stable side-mounted communication cabinet.
The technical scheme that its technical problem that solves the utility model adopts is, a kind of communication cabinet with side heat exchanger is provided, and comprises the rack main body, is provided with the dividing plate that its inner space is separated into equipment compartment and heat exchanger storehouse in the described rack main body; Described heat exchanger storehouse is equiped with heat-exchanger rig; Described heat-exchanger rig is provided with the interior circulation air path that is communicated with the hot-air of introducing described equipment compartment, and the outer circulating air duct of introducing the hot-air of the described interior circulation air path of chilled air cools.Described heat-exchanger rig be included in the interior circulation air inlet that is provided with on the rack contour and in recycle the air port, described dividing plate rack contour be provided with described in the circulation air inlet and in recycle corresponding air outlet in air port and air inlet; Described in the circulation air inlet and in recycle the air port with described air outlet and air inlet is corresponding be tightly connected after, on the rack contour formation in the circulation air path closed-loop.
In the communication cabinet of band side heat exchanger of the present utility model, described heat-exchanger rig is split up into two or more parts that works alone in vertical direction.Each independent sector of described heat-exchanger rig all comprises shell and installation heat exchange core in the enclosure.
In the communication cabinet of band side heat exchanger of the present utility model, the interior circulating fan of described heat-exchanger rig is positioned at the described outer circulation fan that recycles place, air port, heat-exchanger rig and is positioned at described outer circulation air outlet place.
The communication cabinet of band side heat exchanger of the present utility model has following beneficial effect: the interior circulation air path of heat-exchanger rig and the air inlet of equipment compartment are tightly connected on the rack contour mutually with air outlet, form the interior circulation air path closed-loop on the rack contour, make main equipment at differing heights all can obtain cold blast rate about equally, have the advantage that heat exchange is even, heat exchange efficiency is high.In addition, air inlet and in recycle the front side that the air port can be arranged on the front of main equipment, make the cold wind that enters into equipment compartment from air inlet directly enter main equipment, and need not turn round from the main equipment front, improved heat exchange efficiency.In addition, heat-exchanger rig is arranged to two or more parts that works alone in vertical direction, single weight, the volume that this design has alleviated heat-exchanger rig be little, be convenient to installation and removal safeguards, and when breaking down for one, another can keep work, and can not cause the paralysis of whole communication cabinet heat-exchange system, guaranteed the fail safe of rack equipment.In addition, the air outlet of circulation air path and outer circulating air duct made fan be in more satisfactory operational environment all the time in interior circulating fan and outer circulation fan laid respectively at, and increased the service life, and reduced the failure rate of fan.
