The heat dissipation problem of the big fever metering device of class, not only results in reactor class device and crosses cause thermal damage in itself, also result in whole cabinet
Heat dissipation be deteriorated, influence the reliabilities of other heat-sensitive devices.Meaning of the present invention is, finds a kind of efficient, low cost, has grasped
Safeguard reactor class high power device Cooling Solution.
In the prior art, for the Cooling Solution of the big fever metering device of reactor, it is mainly the following：
The prior art 1, the degree of protection for sacrificing cabinet, the perforate on cabinet door-plate, installs ventilation heat exchange device, its is certain
Device temperature can be reduced, but due to separate ventilation in cabinet, easily causes the pollution air outside cabinet, moisture, salt fog to enter
In cabinet, cause failure of insulation generating device damage accident, it is many for seriously polluted area or offshore applications risk.
The prior art 2, using inside reactor install polylith cooled plate radiate to it, such a scheme shortcoming is
The water route of polylith cooled plate is series connection, and cooled plate water line block problem easily occurs, and has one piece of cooled plate to block, whole reactance
Overtemperature damage will occur for device, and reliability is relatively low, and reactor is replaced difficult.And the reactor cost of such a built-in water-cooling plate
It is very high.
The prior art 3, another solution such as Nanche Zhuzhou Electric Locomotive Institute Co., Ltd's application public platform
CN 105656289A's《A kind of radiator of reactor cabinet》, it uses water wind heat exchanger to pusher side reactance, net side reactance
Heat exchange, is then cooled down medium by the scheme that device is cooled down successively by water wind heat exchanger to exterior.Such a solution,
Compared to the prior art 1 and the prior art 2 as above, solve cabinet degree of protection be destroyed, the reactor of built-in water-cooling plate into
The problems such as this high reliability is low, but it is there is also other shortcoming, and one is due to that its water wind heat exchanger is mounted in cabinet
On front door, causing Door of communication apparatus cabinet plate to protrude influences beauty；Second, it pacifies up and down using pusher side reactor and network reactor
The mode of dress, since reactor weight is big, reactor above installation and follow-up maintenance are all very inconvenient.
The content of the invention
The object of the present invention is to provide a kind of string type reactor cooling system.
For this reason, technical solution of the present invention is as follows：
A kind of string type reactor cooling system, including cabinet；Pusher side reactor, leeward chamber, water wind is equipped with cabinet to change
Hot device, wind turbine, network reactor, windward chamber；
Pusher side reactor is disposed in parallel in the bottom of cabinet with network reactor；The top of network reactor is equipped with windward
Chamber；Reactor air gap on the air outlet face network reactor of windward chamber；The top of pusher side reactor is set successively from bottom to top
There are leeward chamber, water wind heat exchanger and wind turbine；The air inlet of the reactor air gap face leeward chamber of pusher side reactor；Leeward chamber goes out
Air port is connected to the air inlet of water wind heat exchanger；The air outlet of water wind heat exchanger is connected to the air inlet of wind turbine；The outlet air of wind turbine
Mouth is vertical with air inlet, and is connected to the air inlet of windward chamber.The cabinet is sealed structure.
Preferably, the junction of the windward chamber 6 and network reactor 5 is equipped with annular seal space.
Preferably, the annular seal space is made of sealing plate.
Preferably, the side sealing plate of the annular seal space and the distance of network reactor out conductor bag are 0~80mm.
Preferably, distance of the lower sealing plate of the annular seal space apart from network reactor bottom surface is 30~400mm.
Compared with prior art, which radiates reactor using water wind heat exchanger,
Cabinet is set to be in high-protection level state；The network reactor and the pusher side reactor are all installed on bottom, are easily installed
Safeguard；It is low compared to the reactor cost of built-in water-cooling plate, reliability is high using air-cooled reactor.
Brief description of the drawings
Fig. 1 is the structure diagram of string type reactor cooling system provided by the invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described further, but following embodiments are absolutely not to this hair
It is bright to have any restrictions.
Embodiment 1：
A kind of string type reactor cooling system, as shown in Figure 1, including cabinet 7, cabinet 7 is sealed structure；Cabinet 7
It is interior to be equipped with pusher side reactor 1, leeward chamber 2, water wind heat exchanger 3, wind turbine 4, network reactor 5, windward chamber 6；The cabinet 7 is
Sealed structure；
Pusher side reactor 1 is disposed in parallel in the bottom of cabinet 7 with network reactor 5；The top of network reactor 5 is equipped with upper
