Abstract
The utility model provides a heat dissipation type axial fan, including motor, cooling device, impeller, the motor with pass through rotation axis connection between the impeller, cooling device is located the motor with in the middle of the impeller, cooling device supplies in the middle of including box, box through -hole that the axis of rotation was passed, fluid cavity, the box is peripheral with the feed liquor pipe and the drain pipe of fluid cavity intercommunication. The utility model discloses a cooling device cools off the axis of rotation, avoids the fan to rotate the heat that produces and is transmitted to the motor by the axis of rotation, leads to the motor to burn out.
Description
Technical field
The utility model belongs to field of ventilation equipment, especially relates to a kind of heat radiating type axial-flow blower.
Background technique
Blower fan is mainly rotated by driven by motor rotatingshaft, the rotatingshaft the other end is connected with impeller, thus impeller is rotated, when impeller rotates for a long time, impeller bearing place can produce a large amount of heats, is passed to motor via rotatingshaft, owing to also can produce heat when motor itself works, therefore long-time running makes the heat of whole blower fan can not get dispersing, and easily makes motor or whole blower fan be burned.
Summary of the invention
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of heat radiating type axial-flow blower, comprise motor, cooling unit, impeller, be connected by rotatingshaft between described motor with described impeller, the liquid inlet pipe and drain pipe that are communicated with described fluid chamber is placed outside the through hole it is characterized in that: described cooling unit is positioned in the middle of described motor and described impeller, described cooling unit comprises casing, passing for described rotatingshaft in the middle of casing, fluid chamber, casing.
Further, the one end near described casing on described liquid inlet pipe is provided with multiple liquid feeding sub-tube, described liquid feeding sub-tube and described liquid inlet pipe one forging molding.
Further, described drain pipe is provided with multiple fluid near one end of described casing and is in charge of, described fluid is in charge of and described drain pipe one forging molding.
Further, described liquid inlet pipe is provided with liquid flowing valve, and described drain pipe is provided with fluid valve.
Further, the two ends of described casing are sealed by flange by described through hole.
Further, cooling liquid is preferably tap water.
The advantage that the utility model has and good effect are:
1, the utility model is cooled rotatingshaft by cooling unit, avoids blower fan to rotate the heat produced and is passed to motor by rotatingshaft, cause motor to burn out;
2, liquid inlet pipe affluent-dividing flows in casing, reduces the impact of liquid to box house to a certain extent, extends the working life of casing;
3, the height of liquid inlet pipe is lower than the height of drain pipe, and the liquid flowed out from drain pipe can continue to flow in liquid inlet pipe at elevated pressures and reuse.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model;
Fig. 3 is the internal structure schematic diagram of cooling unit of the present utility model.
In figure: 1. motor, 2. cooling unit, 21. through holes, 22. fluid chambers, 3. impeller, 4. rotatingshaft, 5. liquid inlet pipe, 6. liquid feeding sub-tube, 7. drain pipe, 8. fluid be in charge of, 9. liquid flowing valve, 10. fluid valve, 11. flanges.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of heat radiating type axial-flow blower, comprise motor 1, cooling unit 2, impeller 3, be connected by rotatingshaft 4 between described motor 1 with described impeller 3, it is characterized in that: described cooling unit 2 is positioned in the middle of described motor 1 and described impeller 3, described cooling unit 2 comprise pass for described rotatingshaft 4 in the middle of casing, casing through hole 21, fluid chamber 22, place the liquid inlet pipe 5 and drain pipe 7 that are communicated with described fluid chamber 22 outside casing.
One end near described casing on described liquid inlet pipe 5 is provided with multiple liquid feeding sub-tube 6, described liquid feeding sub-tube 6 and described liquid inlet pipe 5 one forging molding.Liquid inlet pipe 5 affluent-dividing flows in casing, reduces the impact of liquid to box house to a certain extent, extends the working life of casing.
Described drain pipe 7 is provided with multiple fluid near one end of described casing and is in charge of 8, described fluid is in charge of 8 and described drain pipe 7 one forging molding.
Described liquid inlet pipe 5 is provided with liquid flowing valve 9, and described drain pipe 7 is provided with fluid valve 10.
The height of described liquid inlet pipe 5, lower than the height of described drain pipe 7, is beneficial to and the liquid flowed out in drain pipe 7 can be continued to flow into recycling in liquid inlet pipe 5 at elevated pressures.
The two ends of described casing are sealed by flange 11 by described through hole.
Cooling liquid is preferably tap water.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
