[0020] The technical scheme in the utility model embodiment will be clearly and completely described below in conjunction with the drawings in the utility model embodiment.

[0021] The utility model embodiment provides a kind of automobile oil cooler fin structure, as Figures 1-3 As shown, including fin body 1, first plate 2 being arranged in the upper of fin body 1, second plate 3 being arranged in the lower of fin body 1, first plate 2 and second plate 3 are provided with the fool-proof structure of preventing misplacement when installation, fool-proof structure includes first protrusion 7, second protrusion 5, third protrusion 4, guide slot 6, guide block 8, first protrusion 7 is fixedly connected on one side of first plate 2, and the upper and lower sides of first protrusion 7 are all fixedly connected with guide block 8, second protrusion 5 and third protrusion 4 are respectively fixedly connected on the two sides of second plate 3, and first protrusion 7 and second protrusion 5 correspond to each other, and second protrusion 5 is provided with guide slot 6 matched with guide block 8.

[0022] Through the setting of the fool-proof structure, when the installation direction is correct, the guide block 8 of the first protruding block 7 is directly inserted into the guide slot 6 of the second protruding block 5, when the installation direction is incorrect, the guide block 8 of the first protruding block 7 is blocked by the third protruding block 4, thereby causing one side to be raised, thereby playing a role in preventing incorrect installation, and reducing the assembly error rate.

[0023] The first protruding block 7 is arranged on one side of the first plate 2 in the length direction, and the first protruding block 7 is located at the middle of the side length of the first plate 2.
