Abstract
The utility model provides a fan shaft cooling device and belongs to the technical field of fans, and the fan shaft cooling device is used for solving the problems that a cooling disk is poor in air cooling effect and small in cooling range and further cannot be used for well lowering the high temperature of a fan main shaft and a bearing. The fan shaft cooling device comprises a fan shaft, wherein the fan shaft is provided with a water wheel, a shell is sleeved outside the water wheel, a sealing device is arranged between the shell and the fan shaft, the top of the shell is provided with a water inlet pipe, and one side of the bottom of the shell is provided with a water outlet pipe. The fan shaft cooling device can be used for performing water cooling on fan shafts and is large in cooling range, good in cooling effect and simple in structure.
Description
Technical field
The utility model belongs to the blower fan technical field, refers in particular to a kind of high-temperature blower axle cooling unit.
Background technique
Blower fan is at high-temperature work environment or work long hours; The axle temperature of blower fan axle or very high, can it proper functioning depend on whether drive motor runs well, if because of the drive motor temperature too high; Then cause the motor infringement to cause blower fan to lose efficacy easily; Or, cause bearing failure, thereby cause fan trouble because of electric machine main shaft is conveyed to bearing portion with heat.
At present, be employed in usually on the blower fan and heat dissipation plate to be installed electric machine main shaft and bearing to be carried out air-cooled, but this heat dissipation plate air cooling effect is poor, and cooling extent is little, can not fine solution blower fan main shaft and the high problem of bearing temperature.
Summary of the invention
The purpose of the utility model provides the good water-cooled blower fan axle cooling unit of cooling effect.
The purpose of the utility model is achieved in that blower fan axle cooling unit; Include the blower fan axle; It is characterized in that: on the blower fan axle water wheels are installed, water wheels are set with housing outward, are provided with seal arrangement between housing and the blower fan axle; Described case top is provided with intake pipe, is positioned at housing bottom one side and is provided with outlet pipe.
Through on the blower fan axle, installing water wheels additional, and mixing housing and seal arrangement, is that current pass through on the housing intake pipe and introduce with water, and current are through flowed out by outlet pipe behind the water wheels again, and so circulation and then the heat on the blower fan axle taken away reaches the effect of cooling.
In above-mentioned blower fan axle cooling unit, the concrete structure of described seal arrangement is: the inner of housing is bolted with sealed cover, and the sealed cover of sealed cover and blower fan axle junction is provided with felt.
In above-mentioned blower fan axle cooling unit, described sealed cover is circular, and the inner ring surface of sealed cover is provided with circular groove, and described felt is arranged in the circular groove.
In above-mentioned blower fan axle cooling unit, described case top is provided with bleeder screw.
In above-mentioned blower fan axle cooling unit, the housing bottom of described outlet pipe offside is provided with the water window.
The utility model is compared the outstanding and beneficial technical effects of existing technology:
1, the utility model is to the water cooling of blower fan axle, and cooling extent is big, and cooling effect is good.
2, the utility model hydroecium good airproof performance uses stable.
3, the utility model is simple in structure, and disassembly, cleaning are convenient.
Description of drawings
