For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Combine the following Figures 1 to 9 , describing a glass tempering air grille with uniform cooling and good cooling effect according to an embodiment of the present invention, which is arranged at the air outlet of a cooling fan, and includes an air grille assembly 1, an air inlet sleeve 2 and an air nozzle assembly 3;

[0039] The air inlet end 22 of the air inlet sleeve 2 is connected to the air outlet of the cooling fan, the air outlet end 23 of the air inlet sleeve 2 is connected to the air grille air inlet side 11 of the air grille assembly 1, the air grille air outlet side 12 of the air grille assembly 1 is connected to the air nozzle air inlet side 11 of the air nozzle assembly 3, and the air nozzle air outlet side 33 of the air nozzle assembly 3 faces the glass;

[0040] The wind grille assembly 1 is provided with a plurality of air ducts 15; the air outlet end 23 of the air inlet sleeve 2 is provided with an air guide plate 21, the air guide plate 21 divides the wind grille air inlet side 11 of the wind grille assembly 1 into a plurality of wind grille air inlets 111, the wind grille air inlets 111 correspond to the air ducts 15 one by one, and the wind grille air inlets 111 are in communication with the air ducts 15;

[0041] The air guide plate 21 extends toward the air inlet end 22 of the air inlet sleeve 2, and the cross-sectional area of ​​the air guide plate 21 gradually increases from the air inlet end 22 of the air inlet sleeve 2 toward the air outlet end 23 of the air inlet sleeve 2;

[0042] like Figure 5 As shown, the air outlet side 33 of the air nozzle assembly 3 includes a transition section 31 and an air outlet section 32, and the transition section 31 and the air outlet section 32 are arranged in sequence from near to far from the air grille inlet side 11 of the air grille assembly 1, the transition section 31 is a sealing structure, and the air outlet section 32 is provided with an air nozzle outlet hole 331.

[0043] In the glass tempering wind grid with uniform cooling and good cooling effect, the air guide plate 21 is set on the air inlet sleeve 2 to play a diversion role, and the cooling air generated by the cooling fan is evenly distributed to each air duct 15, so that the air volume of the cooling air obtained by each air duct 15 is the same, thereby making the cooling air blown toward the glass by the wind nozzle assembly 3 uniform; by setting a transition section 31 and an air outlet section 32 on the wind nozzle outlet side 33 of the wind nozzle assembly 3, the cooling air will not immediately enter the wind nozzle outlet hole 331 after entering the wind nozzle assembly 3 from the wind grid outlet side 12 of the wind grid assembly 1 through the wind nozzle inlet side, but will first enter the transition section 31, and then enter the air outlet section 32 after the cooling air is stabilized, and then blow toward the glass through the wind nozzle outlet hole 331, thereby avoiding the formation of vortex in the wind nozzle assembly 3, thereby improving the uniformity of the cooling air.

[0044] In some embodiments, Figure 2 and 3As shown, the air guide plate 21 is a triangular prism structure, and the air guide plate 21 includes a bottom surface 211, a first side surface 212, and a second side surface 213. The bottom surface 211 of the air guide plate 21 is arranged at the air outlet end 23 of the air inlet sleeve 2. The intersection of the first side surface 212 and the second side surface 213 of the air guide plate 21 is a rounded structure, and the intersection of the first side surface 212 and the second side surface 213 faces the air inlet end 22 of the air inlet sleeve 2. When the cooling air enters the interior of the air inlet sleeve 2 from the air inlet end 22, the cooling air flows toward the air outlet section 32 of the air inlet sleeve 2. At this time, the cooling air will hit the intersection of the first side surface 212 and the second side surface 213 of the air guide plate 21, and then the cooling air will be divided into multiple groups of uniform cooling air and enter the corresponding air duct 15. Since the intersection of the first side surface 212 and the second side surface 213 of the air guide plate 21 is a rounded structure, the wind speed of the cooling air can be uniformed and accelerated.

[0045] It is worth noting that if Figure 2 As shown, the air outlet end 23 of the air inlet sleeve 2 is provided with a plurality of air guide plates 21, and the intersection of the first side surface 212 and the second side surface 213 of the air guide plate 21 faces the central axis 24 of the air inlet sleeve 2. Since the cooling air blown from the cooling fan into the air inlet sleeve 2 is parallel to the central axis 24 of the air inlet sleeve 2, when the intersection of the first side surface 212 and the second side surface 213 of the air guide plate 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 guide plate 21, thereby improving the air guiding effect.

[0046] 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 that gradually changes from circular to rectangular. The circular air inlet end 22 of the air inlet sleeve 2 is easy to engage with the air outlet of the cooling fan, and the rectangular air outlet end 23 of the air inlet sleeve 2 is easy to engage with the wind grille inlet side 11 of the wind grille assembly 1. Since the side wall of the air inlet sleeve 2 is a structure that gradually changes from circular to rectangular, the inner wall of the air inlet sleeve 2 is smooth and has no edges and corners. After the cooling air enters the interior of the air inlet sleeve 2, the energy lost is reduced, thereby ensuring that the cooling air maintains a high wind speed when entering the wind grille assembly 1.

[0047] Specifically, the fillet radius R of the intersection of the first side surface 212 and the second side surface 213 of the wind deflector 21 is 3.5-4 mm. When the fillet radius R is less than 3.5 mm, the angle between the first side surface 212 and the second side surface 213 of the wind deflector 21 is too small, and the intersection will lose the effect of uniform wind speed. When the fillet radius R is greater than 4 mm, 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 wind speed will be lost.

[0048] Preferably, the length of the transition section 31 is 60-100 mm. When the length of the transition section 31 is less than 60 mm, the transition section 31 is too short, and it is easy to form a vortex in the nozzle assembly 3; when the length of the transition section 31 is greater than 100 mm, the transition section 31 is too long, occupying too much of the nozzle outlet side 33, resulting in the outlet section 32 being too short, which is not conducive to the cooling of the glass.

[0049] In some embodiments, the wind grille outlet side 12 is provided with a plurality of wind grille outlets, and the wind grille outlets correspond one-to-one with the wind duct 15; the wind nozzle assembly 3 is composed of a plurality of wind nozzle groups 34, and the wind nozzle groups 34 correspond one-to-one with the wind grille outlets, and each group of the wind nozzle groups 34 is provided with a transition section 31 and an outlet section 32, and the length of the transition section 31 of each group of the wind nozzle groups 34 is equal, and the length of the outlet section 32 of each group of the wind nozzle groups 34 is equal. In this way, the air volume of each group of the wind nozzle groups 34 can be kept the same, so that the air volume and wind force of the cooling air blown to each position on the glass are the same, and the glass is cooled evenly.

[0050] It is worth noting that if Figure 6 and 7 As shown, the thickness of the wall surface of the nozzle assembly 3 located at the nozzle air outlet hole 331 is thicker than the thickness of the wall surface located at the non-nozzle air outlet hole 331. In this way, the depth of the nozzle air outlet hole 331 can be extended, thereby improving the guiding effect of the nozzle air outlet hole 331, so that the cooling air can be blown to the surface of the glass more evenly; in addition, the cooling air can also form an air column, and when the cooling air is blown out of the nozzle air outlet hole 331, it is not easy to disperse, so that the cooling air is blown to the glass in a straight line.

[0051] Optionally, a roller 4 is also included, and the air outlet side 33 of the air nozzle assembly 3 faces the roller 4, and the roller 4 is used to transport glass; the glass is arranged on the surface of the roller 4, so that the air outlet side 33 of the air nozzle assembly 3 facing the roller 4 can guide the cooling air to blow toward the surface of the glass to cool the glass.

[0052] like Figure 1As shown, it also includes a frame 5, and the wind grille assembly 1 includes an upper wind grille 13 and a lower wind grille 14. The upper wind grille 13, the roller shaft 4 and the lower wind grille 14 are arranged on the frame 5 in sequence from top to bottom; the glass passes between the upper wind grille 13 and the lower wind grille 14 through the conveying effect of the roller shaft 4, and the upper wind grille 13 guides the cooling wind to blow toward the upper surface of the glass, and the lower wind grille 14 guides the cooling wind to blow toward the lower surface of the glass, thereby improving the efficiency of glass cooling.

[0053] like Fig. 9 As shown, the frame 5 is provided with a mounting plate 51, the mounting plate 51 is provided with a bearing 52, the bearing 52 corresponds to the roller shaft 4 one by one, and the roller shaft 4 is rotatably connected to the bearing 52; a hook 53 is provided on the outer side of the mounting plate 51, and the hook 53 is used to hang equipment spare parts. The equipment spare parts hung on the hook 53 include spare parts such as belts and bearings 52, so that maintenance personnel can easily maintain the components of the equipment.

[0054] Specifically, Figure 8 As shown, the roller shaft 4 is a hollow structure. The roller shaft 4 with a hollow structure has good heat dissipation and can improve the cooling efficiency of the glass. Preferably, the roller shaft 4 is made of 45# steel seamless pipe to improve strength.

[0055] Other structures and operations of a glass tempering air grille with uniform cooling and good cooling effect according to an embodiment of the present invention are well known to ordinary technicians in the field and will not be described in detail here.
