Abstract
The utility model relates to a kind of Novel heat radiating fan structure, is mainly used in claw-pole motor.It is made up of upper fan and lower fan, arranges solder joint inside the flabellum of described fan up and down, and upper fan is connected as a single entity by welding with lower fan; Upper electric fan and lower electric fan staggered, form air channel between adjacent upper fan and lower electric fan, the flabellum of upper and lower fan and outer shroud form closed wind path.Be provided with erection support at lower fan bottom, erection support is reserved with solder joint.The utility model is by welding by two fan weldings to mode together, and make to be installed to epitrochanterian fan end winding support, form the wind path closed, the radiating effect of increase fan, reduces the noise of fan generation.
Description
Technical field
The utility model relates to a kind of for cooling fan structure new in claw-pole motor.
Background technique
Current claw-pole motor fan mainly adopts the mode of punching, straight forming, is installed on rotor by modes such as welding, and the end of fan is unrestricted.Owing to not having to form the air channel closed during this fan work, therefore wind speed is lower, and radiating effect is bad.Simultaneously owing to not fixing the end of fan, vibration during fan work is comparatively large, easily produces larger noise.Above problem all can cause the quality of product to decline.
Summary of the invention
In order to overcome the technical problem of above-mentioned existence, the utility model provides a kind of Novel heat radiating fan structure, can increase the radiating effect of generator, can reduce again the noise of generator, improves the quality of product.
The purpose of this utility model is achieved through the following technical solutions: a kind of Novel heat radiating fan structure, it is characterized in that: be made up of upper fan and lower fan, arrange solder joint inside the flabellum of described fan up and down, upper fan is connected as a single entity by welding with lower fan; Upper electric fan and lower electric fan staggered, form air channel between adjacent upper fan and lower electric fan, the flabellum of upper and lower fan and outer shroud form closed wind path.
Described lower fan bottom is provided with erection support, and erection support is reserved with solder joint.
The beneficial effects of the utility model: the utility model adopts said structure, arranging solder joint, being connected as a single entity by upper fan with lower fan by welding inside the flabellum of upper and lower fan; Form air channel between adjacent upper fan and lower electric fan, the flabellum of upper and lower fan and outer shroud form closed wind path, are conducive to the pressure increasing fan outlet place, increase the ventilation of fan.When assembling, this fan being welded to the surface of pawl pole by the solder joint on lower fan, forming stable structure.When generator normally works, the air quantity that this fan produces is large, good heat dissipation effect, the end winding support of this fan simultaneously, the vibration produced when generator high speed is little, while enhancing radiating effect, effectively reduce the noise of generator, improve the quality of product.

Embodiment
A kind of Novel heat radiating fan structure, as shown in Figure 1, be made up of upper fan 1 and lower fan 2, upper electric fan 3 is staggered with lower electric fan 4, form air channel 5 between adjacent upper fan and lower electric fan, the flabellum of upper and lower fan and outer shroud form closed wind path.
As shown in Figure 2,3, arrange solder joint 6 inside the flabellum of upper and lower fan, upper fan 1 is connected as a single entity by welding with lower fan 2.
As Fig. 6 is provided with erection support 41 bottom lower fan 2, erection support 41 is reserved with solder joint 42.By reserved solder joint 42 during installation, this New Type of Fan is welded to pawl and extremely goes up.
The quantity of upper and lower electric fan can be increased according to the needs of heat radiation, improve the heat radiation of generator further.
