[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 mobile mechanical engine radiators, and discloses a heat dissipation device of an automobile engine. The heat dissipation device comprises a wind protection cover and a fan, the wind protection cover and the fan are coaxially mounted, the wind protection cover comprises a U-shaped ring, and the U-shaped ring comprises 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, a containing groove is defined between the connecting ring and the flexible outer ring, one end of the fan is contained in the containing groove, the end, away from the flexible outer ring, of the connecting ring protrudes towards the fan to form a flexible inner ring, a gap is defined between the peripheral wall of the fan and the flexible outer ring, and the flexible inner ring and the flexible outer ring are made of flexible materials. According to the heat dissipation device of the automobile engine, the U-shaped wind protection cover is assembled smoothly, after-sales processing is convenient and fast, meanwhile, secondary circulation is eliminated, and the efficiency of the fan is improved.

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. ...
