Situation plays certain radiating effect, but this ventilation effect does not has specific aim, in particular for the big merit that self heat production is high
The elements such as rate big load catalyst, often radiating effect is bad, the above-mentioned high-power big load being in for a long time under high-temperature condition
Electric elements will burn, and adds loss and the fault rate of operation equipment in cabinet, adds operation cost.
Utility model content
The deficiency that this utility model exists for above-mentioned prior art, it is provided that a kind of heat dissipation power distribution cabinet, utilizes limited wind
The electric elements air discharging and radiating that amount is big for producing heat targetedly, improves the ventilation and heat effect of high-power big load electric elements
Rate.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of heat dissipation power distribution cabinet, and including cabinet, it is special
Levying and be, described cabinet is provided with cooling mechanism, and described cooling mechanism includes exhaust fan, main ventilation pipe, multiple branch duct
And air draught tube head, described exhaust fan is arranged on the top of described cabinet, and described exhaust fan is arranged on the upper end of described main ventilation pipe
Air outlet position, described main ventilation pipe is provided with multiple branches mouth of pipe, and multiple described branch ducts pass through rotating mechanism respectively
Being connected in parallel on the described branch mouth of pipe, multiple described air draught tube heads are uniform to be arranged on described branch duct；
Described rotating mechanism includes that multi-directional ball and ball seat, one end of described ball seat coordinate with described multi-directional ball, and the other end sets
Having a connecting tube, described connecting tube is threadeded with the described branch mouth of pipe, and the end that described ball seat is connected with described multi-directional ball is provided with
Limit base, described limit base is provided with the groove that the lower surface with described branch duct matches, the fixing peace of described multi-directional ball
It is contained in the end that described branch duct is connected with the described branch mouth of pipe.
The beneficial effects of the utility model are: be extended with multiple branches mouth of pipe on main ventilation pipe, according to merit big in power distribution cabinet
The position of rate big load electric elements selects the most suitable branch mouth of pipe to install branch duct, specifically by the connecting tube of ball seat with
Branch's mouth of pipe connects, owing to ball seat is provided with the reeded limit base of band, it is ensured that branch duct lowest order is that horizontal direction sets
Putting, branch duct can rotate with in main ventilation scope tube in the horizontal direction, it is simple to the electric elements in power distribution cabinet are entered by the later stage
Row is safeguarded, air draught tube head alignment produces the electric elements of the many high-power big load of heat, many to heat radiation targetedly
Electrical equipment is lowered the temperature in time, it is to avoid occur due to asking that the electric elements fault rate height in the too high power distribution cabinet of temperature even damages
Topic.In a word, this utility model simple in construction, easy to operate, and do not affect the I&M of electric elements, moreover it is possible to utilize limited
Air quantity targetedly for producing the big electric elements air discharging and radiating of heat, the ventilation improving high-power big load electric elements dissipates
The thermal efficiency.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described air draught tube head uses universal joint cooling tube.
Using above-mentioned further scheme to provide the benefit that, air draught tube head uses universal joint cooling tube to stretch, permissible
Any direction bending produces, so that being directly directed at high-power big load, the electric elements that heat is many, even if aspiration channel after An Zhuaning
Head does not align, and also allows for postorder and is adjusted.
Further, the top of described cabinet is provided with rain shade, and described rain shade is arranged on the top of described exhaust fan.
Use above-mentioned further scheme to provide the benefit that, keep out wind and rain for exhaust fan, protect exhaust fan.
