Description
Technical field
The utility model belongs to casing cooling technology field, a kind of specifically fan bearing cooling unit.
Background technique
When blower fan turns round, can produce a lot of heats in the bearing housing, if these heats can not in time volatilize, then can cause casing overheated, influence the normal use of blower fan, the timely volatilization of heat energy generally all is provided with cooling system on bearing housing for convenience.Common cooling system comprises intake pipe and the outlet pipe that communicates with box house, intake pipe one end links to each other with water pump, by charging into cooling water in the water pump phase casing, cooling water cools off the part in casing and the casing, flow out from outlet pipe then, this type of cooling can effectively be finished the cooling to bearing housing.But adopt this mode, need externally to be equipped with separately the water pump of the usefulness of drawing water, increased cost, and cooling water is directly discharged from outlet pipe, is not recycled, and can cause the waste and the environmental pollution of water resources.
Summary of the invention
The utility model provides a kind of fan bearing cooling unit at deficiency of the prior art, need not be equipped with water pump separately, and replaces water as cooling medium with air, can waste water resource and befouling environment.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: the fan bearing cooling unit, comprise rotating shaft, clutch shaft bearing, second bearing, the clutch shaft bearing case and second bearing housing, described rotating shaft links to each other with second bearing with described clutch shaft bearing, described clutch shaft bearing is arranged in the described clutch shaft bearing case, described second bearing is arranged in described second bearing housing, also comprise first shell and second shell, described first shell is arranged on outside the described clutch shaft bearing case, described second shell is arranged on outside described second bearing housing, described first shell is provided with first opening and second opening, described second opening is outside equipped with impeller, described impeller is fixed in the described rotating shaft, described second shell is provided with the 3rd opening, described rotating shaft hollow, and described rotating shaft is provided with first through hole and second through hole, described first through hole is communicated with described first enclosure and described rotating shaft inside, and described second through hole is arranged at described impeller place.During work, the rotating shaft impeller is rotated, and impeller is to being provided with bearing housing one side draught gas, with the first opening suction of air from first shell, extracts out from second opening then on the one hand, and in this process, the heat that clutch shaft bearing produces is taken away; On the other hand, impeller is with the three opening suction of air from second shell, discharge behind the passage by hollow in the middle of first through hole, rotating shaft and second through hole then, the heat that second bearing produces is taken away, so just finished the cooling of two bearing housings of blower fan.Certainly impeller also can also can reach same effect to a side-blown gas that is provided with bearing housing.
In the technique scheme, in order to make bearing better cool off, also be provided with third through-hole and fourth hole in the described rotating shaft, described third through-hole is communicated with described first enclosure and described rotating shaft inside, and described fourth hole is communicated with described second enclosure and described rotating shaft inside.
The beneficial effects of the utility model are: 1, load onto impeller in rotating shaft, and after impeller outer is loaded onto housing, just having formed a blower fan, the blower fan of this formation is driven by rotating shaft, or thereby need not externally to install other power plant of water pump, significantly reduced cost.
2, cooling medium has changed air into by water, and the conserve water resource is especially suitable in the area of some lacks of water in a large number; And, can take the pollutants such as greasy dirt in the casing out of the time with water, can cause environmental pollution, and air draught be not easy to take out of pollutant, significantly reduce environment damage as cooling medium.
