a plurality of mounting blocks (22) detachably connected with the automobile radiator (1) are arranged on the periphery of the air inlet grille framework, and mounting holes are formed in the mounting blocks (22);
the automobile radiator (1) is provided with a fixing hole (12) matched with the mounting block (22), and the mounting block (22) is connected with the fixing hole (12) of the automobile radiator (1) through a bolt (4).
4. The control method of an automobile radiator assembly integrated with an air intake adjusting grill as recited in claim 2, wherein:
the rectangular outer frame (21), the transverse partition plate and the vertical partition plate (24) are all hollow pipe body structures, and the driving device (241) is fixedly installed in the rectangular outer frame (21), the transverse partition plate or the vertical partition plate (24).
5. The control method of an automobile radiator assembly integrated with an air intake adjusting grill as recited in claim 1, wherein:
the driving device (241) is a stepping motor or a servo motor, and an output shaft of the stepping motor or the servo motor is connected with the end part of the grating sheet (25) so as to adjust the rotating angle of the grating sheet (25).
6. The control method of an automobile radiator assembly integrated with an air intake adjusting grill as recited in claim 1, wherein:
the automobile radiator is characterized by further comprising a controller (23), wherein the controller (23) is electrically connected with the driving device (241), and the controller (23) controls the rotating angle of each grid sheet (25) through the driving device (241) after acquiring a temperature signal of the automobile radiator (1).
7. The control method of an automobile radiator assembly integrated with an air intake adjusting grill as recited in claim 1, wherein:
the air inlet grille is characterized in that a resetting device (242) connected with the air inlet grille frame is arranged on the grille plate (25), and the resetting device (242) drives the grille plate (25) to open an air inlet channel.
8. The control method of an automobile radiator assembly integrated with an air intake adjusting grill as recited in claim 7, wherein:
the reset device (242) is a spring which elastically drives the grating sheet (25) to rotate.
9. A control method of an air intake adjusting grill integrated automobile radiator assembly as set forth in any one of claims 1 to 8, wherein:
