Problems solved by technology

[0003] At present, the most widely used in the market are such as figure 1 In the open windshield 2 shown, the fan 21 is a high-speed rotating part. In order to prevent structural damage caused by dynamic interference during the movement, a certain gap 3 must be maintained between the fan 21 and the open windshield 2. For the open The air cover 2 and the fan 21, the blade tip clearance of the fan 21 will produce obvious secondary circulation, thereby reducing the efficiency of the fan

Abstract

The invention relates to the technical field of engine radiators for mobile machinery, and discloses a heat dissipation device for an automobile engine of the present invention, which includes a windshield and a fan, the windshield and the fan are coaxially installed, the windshield includes a U-shaped ring, The type ring includes a flexible outer ring, a flexible inner ring and a connecting ring. The connecting ring is connected to the inner end of the flexible outer ring and defines an accommodation groove with the flexible outer ring. One end of the fan is accommodated in the accommodation groove, and the connecting ring is away from the flexible outer ring. One end protrudes toward the fan direction to form a flexible inner ring, a gap is defined between the outer peripheral wall of the fan and the flexible outer ring, and the materials of the flexible inner ring and the flexible outer ring are flexible materials. The heat dissipation device of the automobile engine of the present invention enables smooth assembly of the U-shaped windshield and convenient after-sales treatment, eliminates secondary circulation and improves fan efficiency at the same time.

Description

technical field [0001] The invention relates to the technical field of radiators for mobile machinery engines, in particular to a radiator for automobile engines. Background technique [0002] The windshield acts as a connecting channel that transitions from the square radiator to the circularly moving axial flow cooling fan, which can effectively improve fan efficiency, make the airflow through the radiator core evenly distributed, and reduce the backflow of hot air in the engine compartment. [0003] At present, the most widely used in the market are such as figure 1 In the open windshield 2 shown, the fan 21 is a high-speed rotating part. In order to prevent structural damage caused by dynamic interference during the movement, a certain gap 3 must be maintained between the fan 21 and the open windshield 2. For the open The air cover 2 and the fan 21, the tip clearance of the fan 21 will produce obvious secondary circulation, thereby reducing the efficiency of the fan. ...
