The use of a fan as a heat sink is a common structure. A conventional fan 10 is mainly composed of a plurality of blades 1 and a body 102, and the blades 101 are arranged in the body 102. The circumference and the edge 102 are used to accommodate a motor (not shown) to rotate the blade (8) to form an air flow by driving the impeller to rotate. In order to solve the high temperature phenomenon brought about by the continuous improvement of the functions of electronic products, the conventional technology mostly increases the air volume and wind pressure to achieve the fan 10 = this increase. However, when the air volume and the wind pressure are increased by the high-speed rotation of the motor or the area of the fan blade 101, the yaw and vibration of the blade are particularly serious, and therefore the structure of the fan 10, particularly the strength of the casing 102, will be Affected, even causing damage to the casing 1〇2. To solve the above problem, as shown in the figure, a conventional technique is to provide a plurality of ribs 3 on the top 1021 of the casing 丨〇 2 to enhance the structural strength of the casing i 〇 2 to reduce the stress.
