Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a hot air backflow prevention device for radiators. Background Art

[0002] The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system consists of three parts: the water inlet chamber, the water outlet chamber, the main plate and the radiator core. The hot air reflux phenomenon refers to the phenomenon that the hot air discharged from the air-cooled radiator returns to the air-cooled fan suction port, causing the air temperature at the air-cooled radiator inlet to rise. The hot air reflux will reduce the heat transfer efficiency of the radiator, thereby reducing the heat dissipation performance and directly affecting the operation of the automobile engine. For this reason, we propose a device to prevent hot air reflux for the radiator. Utility Model Content

The front side of the exhaust box 21 is fixed with a fixed frame 51, and two corresponding movable bars 52 are arranged inside the fixed frame 51. The two movable bars 52 are located on the left and right sides of the mounting plate 1. A threaded hole is opened on the right side of the movable bar 52. The threads of the two threaded holes are opposite. The internal threads of the two threaded holes are connected with a bidirectional screw 53. The bidirectional screw 53 is welded by two threaded rods with opposite threads. A rotating hole is opened on the right side of the fixed frame 51. The internal rotation of the rotating hole is connected with a toggle rod 54. The bidirectional screw 53 is fixed at the right end of the toggle rod 54.
