Outer loudspeaker are connected with, inside trumpet is provided with positioned at the inside of outer loudspeaker, outlet passageway is formed between the outer loudspeaker and inside trumpet；Institute
State between porous plate and inside trumpet and to be connected by connecting pole.
Further scheme, the porous plate is cylindric plate body, and the center is offered to be threadedly coupled with the connecting pole
Screwed hole, equably offer stomata on the plate body of screwed hole periphery, the distance at the stomata and screwed hole center is not
Less than the radius of the connecting pole.
The connecting pole includes cylinder, and the two ends of the cylinder are installed with screw rod respectively.
Further scheme, the outer loudspeaker are the horn-like structure of both ends open, and its affixed oriented outer wall of its port of export prolongs
The bulge loop stretched；The inside trumpet is the small horn-like staving in the big bottom of mouth, and the bottom center of the staving is offered and the connection
The circular hole of post connection, the openend of staving is connected with the boss of outside loudspeaker direction extension；Formed between the bulge loop and boss
The insufflation channel being connected with the outlet passageway.
Base plays fixed blower fan and the overall effect of support meanss in the utility model, and blower fan is to provide wind for device
Source.Blower fan connects wind direction being converted to horizontality from plumbness by bend pipe, then by porous plate by wind from turbulent flow
Condition conversion is laminar condition, and finally the insufflation channel between the outlet passageway and bulge loop and boss between inside and outside loudspeaker is total to
Under same-action, wind shift is the Zhou Xiangfeng perpendicular to bend pipe.
On the one hand bend pipe plays distinguished and admirable guiding function, on the other hand plays stable support porous plate, connecting pole, inside and outside loudspeaker
Effect；The effect of porous plate be transformation wind direction fluidised form and the wind direction being fixedly connected in post and inside trumpet, bend pipe be flow to it is miscellaneous
Random turbulence state, is constrained by each hole of porous plate, and is changed into the uniform laminar flow of orientation；It is porous that connecting pole mainly plays connection
The effect of plate and inside trumpet；The effect of inside trumpet is point to lead and extrude distinguished and admirable, and wind shift is week by outer loudspeaker collective effect
To flowing out and ensure that circumferential air-out is uniform, so as to be effectively prevented from during circular or annular die head extrusion bar inhomogeneous cooling and
Material strip is adhered, and the more existing type of cooling has some superiority, and the apparatus structure is simple, cheap, is anticipated with positive popularization
Justice.
Inside trumpet is designed as horn-like bucket body structure by the utility model, is mainly based upon loss of weight needs, and is used solid
Inside trumpet can equally realize function of the present utility model.
