Description
Technical field
The utility model relates to a kind of electrical control cubicles, particularly a kind of heat abstractor of electrical control cubicles.
Background technology
Traditional electrical control cubicles heat abstractor is provided with the hot-air outflow in the axial fan guiding electrical control cubicles at air inlet and air outlet position usually, thereby reaches the purpose of electrical control cubicles heat radiation, yet; Axial fan belongs to Motor Control; Have certain failure rate, if axial fan is shut down suddenly, the hot-air in the electrical control cubicles can't be derived; Must cause unnecessary loss to the electric elements in the electrical control cubicles; Simultaneously, use the axial fan heat radiation to exist the cost problem that has improved the electrical control cubicles heat abstractor, on electrical control cubicles, offering the demand that easy thermovent does not often reach heat radiation again; The heat that can not shed must influence the electric elements in the electrical control cubicles, causes the shortening in electric elements life-span; Moreover in existing electrical control cubicles, its heat abstractor is installed on the cabinet usually; Because heat abstractor and heater have the certain space distance, heater is discharged hot gas from exhaust outlet after, because of exhaust outlet can not form good opposite joining relation with air outlet; Thereby the inner hot gas of electrical control cubicles can not form the stable flow direction; In electrical control cubicles, form sinuous flow, the hot gas in the electrical control cubicles is not easy to discharge outside the electrical control cubicles, and the radiating efficiency of the heat abstractor of its electrical control cubicles is not high.
Summary of the invention
In view of this, the purpose of the utility model provides the heat abstractor of a kind of radiating efficiency electrical control cubicles high and with low cost.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of heat abstractor of electrical control cubicles; Comprise the air inlet of electrical control cubicles bottom setting and the air outlet that electrical control cubicles top is provided with, between the exhaust outlet of heater exhaust duct is set in said air outlet and the electrical control cubicles.
Said air outlet is arranged at the electrical control cubicles top.
Said electrical control cubicles top is provided with overhead guard, and overhead guard is inner to be communicated with air outlet, and overhead guard one side is provided with the blinds air outlet.
Said air inlet is arranged at the bottom of electrical control cubicles cabinet door.
Said air inlet is arranged at two sides, electrical control cubicles bottom.
Said air inlet is set to the blinds air inlet.
Said blinds air inlet inboard is provided with screen pack.
Said screen pack inboard is provided with axial fan.
When said heater is a plurality of being set up in parallel, in the said exhaust duct dividing plate is set, in exhaust duct, forms independently heat dissipation channel of each heater.
Said heater is a frequency converter.
The beneficial effect of the utility model is: the heat abstractor of the electrical control cubicles of the utility model is provided with exhaust duct because of it, has directly cancelled axial fan, not only makes stable outflow of hot gas in the electrical control cubicles; Also reduced the failure rate of electrical control cubicles heat abstractor greatly, directly got rid of hot gas, the hot gas alluvial that can in electrical control cubicles, not circulate through exhaust duct; The raising that the efficient of its heat radiation is also relative, moreover exhaust duct has replaced the axial fan heat radiation; Cost has also obtained effective control, also have air outlet to be arranged at the electrical control cubicles top, and air inlet is arranged at the electrical control cubicles bottom; Utilize the principle at hot gas upper reaches fully, made radiating effect more; The overhead guard that the electrical control cubicles top is provided with has played and has prevented that dust from falling into the effect of exhaust duct; The blinds air inlet is set the electrical control cubicles of the utility model and screen pack all has dustproof effect preferably; Dust was filtered out before getting into electrical control cubicles; Its axial fan is arranged at air inlet, plays booster action for the air inlet of electrical control cubicles, also can not influence the damage of the electric component in the electrical control cubicles even axial fan breaks down; Because the air exhausting device that heater carries is discharged hot gas through exhaust duct; Just can produce negative pressure in the electrical control cubicles, because action of negative pressure, the outer air of electrical control cubicles can not get in the electrical control cubicles down through the auxiliary of axial fan equally; Thereby form complete heat radiation circulation, particularly can form separately independently heat dissipation channel through the dividing plate that is provided with for each heater that is set up in parallel.
