Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0017] Such as figure 1 , figure 2 , image 3 In the radiator fan air guide shown, four rectangular side plates 3, 4, 5, 6 and a square bottom plate 7 with ventilation holes in the middle are welded together, and welded to the installation frame 8 of the air guide 1, A thin plate is formed into a circle as large as the middle hole of the main board 7 to form a ring 9, and the ring 9 is welded to the middle hole of the main board 7 to form the outlet of the air guide cover 1; 10 is installed on at least two of the four inner corners of the air guide cover 1, and finally the assembled air guide cover 1 is installed on the radiator 2.

[0018] The manufacture method of deflector block 10:

[0019] 1) Casting: direct casting of the guide block 10 by using a casting method;

[0020] 2) Stamping: use the stamping method to open the mold to punch out the...

Abstract

The invention discloses a radiator fan wind scooper, and relates to the technical field of engineering machinery manufacturing. For the radiator fan wind scooper, a diversion block is arranged on each of at least two of four inner corner parts of the original wind scooper, so the straight ribs of the inner corner parts of the original radiator fan wind scooper is turned into rounding-off angles; and the hot air generated by the radiator is smoothly discharged out of the radiator without generation of turbulent flow blocking the flow while passing through the smooth curves of the diversion blocks on the inner corner parts of the radiator fan wind scooper, so the cooling efficiency of the radiator is improved. The radiator fan wind scooper disclosed by the invention has characteristics of being low in manufacturing cost and strong in university.

Description

technical field [0001] The invention relates to the technical field of construction machinery manufacturing, in particular to a radiator fan air guide cover used on construction machinery. Background technique [0002] When the loader is working, the engine inside it will generate a lot of heat, which is transferred to the radiator pipe through the coolant flowing through the engine block, and then sucked out by the cooling fan through the radiator fan windshield. off-board. [0003] The core of the radiator used in construction machinery is usually rectangular, and the cooling fan is circular. The air guide is used as a connecting channel to guide the hot air from the radiator to the cooling fan. One end of the shape is matched with the core of the radiator. Rectangular, and the other end is round because it needs to accommodate the fan blades of the cooling fan. This kind of radiator fan shroud is currently manufactured by bending and tailor welding. [0004] The radiat...
