The following describes, with reference to fig. 1 to 9, a glass reinforced plastic air grid with uniform cooling and good cooling effect according to an embodiment of the present invention, which is disposed at an air outlet of a cooling fan and includes an air grid assembly 1, an air inlet sleeve 2, and a nozzle assembly 3;
the air inlet end 22 of the air inlet sleeve 2 is connected with the air outlet of the cooling fan, the air outlet end 23 of the air inlet sleeve 2 is connected with the air grid inlet side 11 of the air grid assembly 1, the air grid outlet side 12 of the air grid assembly 1 is connected with the air nozzle inlet side 11 of the air nozzle assembly 3, and the air nozzle outlet side 33 of the air nozzle assembly 3 faces towards the glass;
a plurality of air channels 15 are arranged in the air grid assembly 1; an air deflector 21 is arranged at an air outlet end 23 of the air inlet sleeve 2, the air deflector 21 divides the air grid inlet side 11 of the air grid assembly 1 into a plurality of air grid inlets 111, the air grid inlets 111 correspond to the air channels 15 one by one, and the air grid inlets 111 are communicated with the air channels 15;
the air deflector 21 extends towards the air inlet end 22 of the air inlet sleeve 2, and the cross-sectional area of the air deflector 21 gradually increases from the air inlet end 22 of the air inlet sleeve 2 to the air outlet end 23 of the air inlet sleeve 2;
as shown in fig. 5, the tuyere air-out side 33 of the tuyere assembly 3 includes a transition section 31 and an air-out section 32, the transition section 31 and the air-out section 32 are sequentially arranged from near to far of the air grid air-in side 11 of the air grid assembly 1, the transition section 31 is a sealing structure, and the tuyere air-out hole 331 is opened in the air-out section 32.
In the glass tempering air grid with uniform cooling and good cooling effect, the air deflector 21 is arranged on the air inlet sleeve 2 to play a role of shunting, cooling air generated by the cooling fan is evenly distributed to each air channel 15, so that the air quantity of the cooling air obtained by each air channel 15 is the same, and the cooling air blown to the glass by the air nozzle component 3 is uniform; through in tuyere air-out side 33 of tuyere subassembly 3 sets up changeover portion 31 and air-out section 32, makes the cooling air follow the 12 ways of air grid air-out side of tuyere subassembly 1 the tuyere air-in side gets into behind the tuyere subassembly 3, can not get into tuyere exhaust vent 331 immediately, but advance to go into behind the changeover portion 31, make the steady back of cooling air reentrant air-out section 32, then the warp tuyere exhaust vent 331 blows to glass, avoids forming the vortex at tuyere subassembly 3 to improve the homogeneity of cooling air.
In some embodiments, as shown in fig. 2 and 3, the air deflector 21 has a triangular prism structure, the air deflector 21 includes a bottom surface 211, a first side surface 212, and a second side surface 213, the bottom surface 211 of the air deflector 21 is disposed at the air outlet end 23 of the air inlet sleeve 2, a joint of the first side surface 212 and the second side surface 213 of the air deflector 21 has a rounded corner structure, and a joint of the first side surface 212 and the second side surface 213 faces the air inlet end 22 of the air inlet sleeve 2. After the cooling air enters the air inlet sleeve 2 from the air inlet end 22, the cooling air flows towards the air outlet section 32 of the air inlet sleeve 2, and at this time, the cooling air collides with the joint of the first side surface 212 and the second side surface 213 of the air deflector 21, and then the cooling air is divided into multiple groups of uniform cooling air and enters the corresponding air channels 15. Because the joint of the first side surface 212 and the second side surface 213 of the air deflector 21 is a round angle structure, the wind speed of the cooling wind can be uniform and accelerated.
It should be noted that, as shown in fig. 2, the air outlet end 23 of the air inlet sleeve 2 is provided with a plurality of air deflectors 21, and a joint of the first side surface 212 and the second side surface 213 of the air deflectors 21 faces the central axis 24 of the air inlet sleeve 2. Because the cooling air blown into the air inlet sleeve 2 from the cooling fan is parallel to the central axis 24 of the air inlet sleeve 2, when the joint of the first side surface 212 and the second side surface 213 of the air deflector 21 faces the central axis 24 of the air inlet sleeve 2, the cooling air can be better guided to enter the air duct 15 along the first side surface 212 or the second side surface 213 of the air deflector 21, so that the air guiding effect is improved.
Optionally, the cross section of the air inlet end 22 of the air inlet sleeve 2 is circular, the cross section of the air outlet end 23 of the air inlet sleeve 2 is rectangular, and the side wall of the air inlet sleeve 2 is a structure gradually changed from circular to rectangular.

Because the side wall of the air inlet sleeve 2 is of a structure which is gradually changed from a circular shape to a rectangular shape, the inner wall of the air inlet sleeve 2 is smooth and has no edges and corners, and after cooling air enters the air inlet sleeve 2, the lost energy is reduced, so that the cooling air can be ensured to keep high wind speed when entering the air grid assembly 1.
Specifically, the fillet radius R at the intersection of the first side surface 212 and the second side surface 213 of the air deflector 21 is 3.5-4 mm. When the fillet radius R is less than 3.5mm, the angle between the first side surface 212 and the second side surface 213 of the air deflector 21 is too small, and the effect of uniform wind speed is lost at the joint. When the fillet radius R is larger than 4mm, the angle between the first side surface 212 and the second side surface 213 of the wind deflector 21 is too large, and the effect of accelerating the wind speed is lost.
Preferably, the length of the transition section 31 is 60 to 100 mm. When the length of the transition section 31 is less than 60mm, the transition section 31 is too short, and a vortex is easily formed in the tuyere assembly 3; when the length of the transition section 31 is greater than 100mm, the transition section 31 is too long, and occupies too many air outlet sides 33 of the air nozzles, so that the air outlet section 32 is too short, and the cooling of the glass is not facilitated.

Therefore, the air outlet quantity of each air nozzle group 34 can be kept the same, so that the air quantity and the wind power of cooling air blown to each position on the glass are the same, and the glass is cooled uniformly.
It is noted that, as shown in fig. 6 and 7, the wall surface of the tuyere assembly 3 located at the tuyere discharging hole 331 has a thickness thicker than that of the wall surface located at the non-tuyere discharging hole 331. Therefore, the depth of the air outlet holes 331 of the air nozzles can be prolonged, so that the flow guiding function of the air outlet holes 331 of the air nozzles is improved, and cooling air is blown to the surface of the glass more uniformly; in addition, the cooling air can form an air column, and when the cooling air is blown out from the air nozzle air outlet 331, the cooling air is not easy to scatter, so that the cooling air is blown to the glass linearly.
