Henan Chalco has developed a flat oval aluminum tube for automobile radiator, including an aluminum tube body. The overall section of the aluminum tube body is oblong and oblong. The internal surface of the aluminum tube body is processed into a toothed structure. Two long tube walls in the aluminum tube body are connected with several reinforcing ribs which are parallel to each other.
 
A flat oval aluminum tube for automobile radiator, including an aluminum tube body (1), which is characterized in that the cross section of the aluminum tube body (1) is overall oblate, the inner surface of the aluminum tube body (1) is processed into a toothed structure, the number of teeth is 16-18, the tooth height h is 1.10-1.25 mm, and the longer two tube walls in the aluminum tube body (1) are connected Several stiffeners (2) parallel to each other. The drawings are as follows
The utility model adopts flat oval aluminum tube for automobile radiator, which obviously improves the heat dissipation effect and use reliability of the automobile radiator, and eliminates the defects of the side leakage of the existing automobile radiator; the internal surface of the aluminum tube is processed into a toothed structure, which reduces the cost of raw materials and increases the area of the heat dissipation aluminum tube; the inner wall of the aluminum tube body is provided with reinforcing ribs, which can effectively support the tube wall, so as to The heat sink is not easy to be damaged, which greatly improves the quality and application range of the heat sink aluminum tube.
