Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a stable structure type aluminum heat sink comprises an aluminum heat sink main body 1, heat sinks 5 are uniformly arranged on the aluminum heat sink main body 1, the heat sinks 5 are of the existing heat sink structure for heat dissipation, a fixing bottom plate 3 is arranged at the lower end of the aluminum heat sink main body 1, the upper end of the fixing bottom plate 3 is connected with a base 4 which is integrated with the heat sinks 5 into a whole, the length of the fixing bottom plate 3 is equal to that of the base 4, the width of the fixing bottom plate 3 is larger than that of the base 4, the structure can be realized in such a way that after the fixing bottom plate 3 is fixed at the lower end of the base 4, two opposite sides of the upper end of the fixing bottom plate 3 can be provided with spaces for fixing a connecting strip 7, two opposite sides of the fixing bottom plate 3 are provided with limiting grooves 2, two sides of the limiting grooves 2 are arc-shaped structures, the limiting grooves 2 can play a limiting role on the internal clamping structure through the arc-shaped structures at two sides, and avoid the clamping structure in the limiting grooves 2 from moving up and down, the two ends of the two opposite sides of the fixed bottom plate 3 are uniformly provided with limiting grooves 2, the two sides of the fixed bottom plate 3 are both provided with connecting strips 7, limiting blocks 9 are clamped in the limiting grooves 2, the upper ends of the limiting blocks 9 and the connecting strips 7 are of an integral structure, the clamping of the limiting blocks 9 and the limiting grooves 2 can play a role in connecting the connecting strips 7 and the fixed bottom plate 3, one side of each connecting strip 7 is uniformly connected with a supporting strip 6, the supporting strips 6 are clamped between the radiating fins 5, the height of each supporting strip 6 is equal to the height of each radiating fin 5, the width of each supporting strip 6 is smaller than the distance between the radiating fins 5, the structure can prevent the supporting strips 6 from contacting with the radiating fins 5, so that the supporting strips 6 can be conveniently clamped between the radiating fins 5, after the radiating fins 5 are impacted, the radiating fins 5 can be prevented from being extruded together through the support of the supporting strips 6, and the use of the aluminum radiating fin main body 1 is prevented from being influenced, fixing groove 8 has been seted up to one side upper end that connecting strip 7 is close to fin 5, and support bar 6 is in fixing groove 8, and this structure makes connecting strip 7 can avoid and fin 5 between contact through fixing groove 8 to prevent that connecting strip 7 from influencing the heat dissipation of fin 5 and using.
