Useful part lies in: the utility model discloses a protecting solar or lunar halo and having carried out the optimal design according to the hydrodynamics theory, simple structure, processing low cost under the prerequisite of guaranteeing to satisfy the cooling amount of wind through the radiator, reduce the vortex and disorderly intensity of ye ding clearance department, can improve the air orbit that flows, improve engineering vehicle's whole car noise quality, effectively reduce the vehicle noise.
Description
Technical field
The utility model relates to a kind of cooling fan and protects solar or lunar halo, is specifically related to a kind of cooling fan with air draft diffusion hole and protects solar or lunar halo; Belong to technical field of engineering machinery.
Background technique
The internal flow of cooling fan is extremely complicated three-dimensional viscous flows, cooling fan is adopted to provide cold wind to carry out the engineering vehicle cooled for cooling system, its noise is mainly derived from the cooling fan of High Rotation Speed, radiator is passed through most effectively in order to make cold wind, general all employing protects the diversion section of solar or lunar halo as cooling fan and radiator, certainly exists blade tip clearance.Empirically, blade tip clearance general control is within the scope of about 2% fan diameter, because the linear velocity at cooling fan blade tip place is maximum, adopt and of the prior artly protect solar or lunar halo, although effectively water conservancy diversion can be carried out to moving air, improve the radiating efficiency of radiator, but there is more eddy current and disorder in blade tip clearance (cooling fan and the gap protected between solar or lunar halo) place, this is one of source of cooling fan aerodynamic noise, in order to reduce noise, needs the structure of cooling fan being protected to solar or lunar halo to improve.
Model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of cooling fan with air draft diffusion hole to protect solar or lunar halo, to destroy eddy current and the disorder of moving air, and improvement air flow trace, thus effectively reduce vehicle noise.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
Cooling fan with air draft diffusion hole protects a solar or lunar halo, comprising: radiator joint, fan protective net joint and the transition part both connection, and the sectional shape of described radiator joint is rectangle, and the sectional shape of described fan protective net joint is circular; Described radiator joint is provided with bar shaped mounting flange, described bar shaped mounting flange is formed with first kind attachment hole; Described fan protective net joint is provided with circular mounting flange, described circular mounting flange is formed with Equations of The Second Kind attachment hole; The perisporium of described fan protective net joint is formed with some air draft diffusion holes.
Particularly, this protects solar or lunar halo and is made up of thin plate welding.
More specifically, aforementioned bar shaped mounting flange is two, is connected on the relative both sides of radiator joint.
Preferably, the sectional dimension of aforementioned heat sink joint is greater than the sectional dimension of fan protective net joint.
More preferably, between the wallboard place plane in foregoing transition portion and the cross section of radiator joint, there is angle.
Further, aforementioned air draft diffusion hole is by axial arranged two row, and column pitch is 10 ~ 15mm.
Preferably, the diameter of aforementioned air draft diffusion hole is 10mm.
More preferably, adjacent two row air draft diffusion holes are staggered is evenly arranged.
Usefulness of the present utility model is: the solar or lunar halo that protects of the present utility model is optimized design according to Hydrodynamics Theory, structure is simple, low processing cost, under ensureing to meet the prerequisite by the cooling air quantity of radiator, reduce the eddy current at blade tip clearance place and disorderly intensity, air flow trace can be improved, improve the car load noise qualities of engineering vehicle, effectively reduce vehicle noise.
