Pipe 730 flows downward, and can carry out adequately heat exchange cooling to the air flowed through in cooling tubule 730 in the process, so that into
The air themperature for entering cabinet 100 is lower, has more preferably endothermic effect.
As shown in Fig. 7, multiple spraying apertures 750 are surround and uniform intervals are opened in the second branch pipe 530；Spraying smallmouth
The bore of 760 outlet end is less than the aperture of spraying aperture 750, and 760 outlet end of spraying smallmouth of more small-bore possesses preferably
Atomizing effect, the aperture of the outlet end of spraying aperture 750 is preferably 0.1mm in the present embodiment；The direction setting of spraying smallmouth 760
The flow direction of air is on the contrary, in the unit time in direction and cooling tubule 730 obliquely, to may make injection steam in this way
Heat exchange cooling can be carried out to more air；And the angle between spraying smallmouth 760 and the tube wall of the second branch pipe 530 is set as
30 °~60 ° (being preferably 45 ° in the present embodiment)；Multiple gully-holes 780 are surround and uniform intervals are opened in the second branch pipe 530.If
Multiple gully-holes 780 are set to collect the water flowed down from cooling tubule 730 and be delivered to water tank 840 by outlet pipe 830, are followed
Ring uses.
In addition, spraying smallmouth 760 can also be preferably the spray of two fluid air atomizings in order to obtain better atomizing effect
Mouth；Cooling tubule 730 is preferably also copper pipe.
In addition, being provided with temperature sensor (not shown) and controller (not shown) in pressure change chamber 320；Water pump 810, air inlet
Fan 560 and axial flow blower, which are controlled with controller, to be connected.
Through the above technical solutions, intelligent control can be realized to this Wind-cooling type compact box substation, it is specific: to work as temperature
Degree sensor detects that pressure change chamber 320 (because the temperature of mainly transformer 420 in case change is relatively high, therefore preferentially detects pressure change chamber
Temperature in 320) in temperature when reaching the first preset temperature value (such as 50 DEG C), 560 He of air inlet fan is immediately controlled in controller
Axial flow blower starting, greatly speeds up heat dissipation air circulation, to reduce the temperature of each chamber in cabinet 100；When temperature sensor is examined
When measuring the temperature in pressure change chamber 320 and reaching the second preset temperature value (such as 70 DEG C), controller controls the starting of water pump 810 immediately,
And then carry out carrying out steam spray in cooling tubule 730, the temperature into 100 air of cabinet is further decreased, to strengthen
Radiating and cooling effect；When temperature sensor detects the temperature in pressure change chamber 320 lower than the first preset temperature value (50 DEG C), control
Device control air inlet fan 560 processed and axial flow blower stop working；When temperature sensor detects that the temperature in pressure change chamber 320 is lower than
When the second preset temperature value (70 DEG C), controller control water pump 810 stops working；So in winter or when ambient temperature is lower
It can stop wind cooling temperature lowering, to achieve the purpose that intelligent control, energy-saving.
