[0031] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0032] like Figure 1As shown, in one embodiment of this utility model, the blade structure of the radiator includes a first protective plate 1, a second protective plate 2, an inner mounting body 3, and a flow guide inner body 4; the first protective plate 1 and the second protective plate 2 are arranged side by side; the flow guide inner body 4 is connected between the first protective plate 1 and the second protective plate 2, and an airflow cavity 6 is provided between the flow guide inner body 4, the first protective plate 1, and the second protective plate 2; the inner mounting body 3 is connected to the second protective plate 2, and the inner mounting body 3 extends toward the first protective plate 1; and an assembly cavity 5 is provided between the inner mounting body 3, the second protective plate 2, and the flow guide inner body 4; the assembly cavity 5 communicates with the airflow cavity 6.

[0033] The technical solution of this utility model uses the clamping and assembly action of the second guard plate and the first guard plate on the inner body of the guide to ensure a stable airflow cavity formed between the inner body of the guide, the first guard plate and the second guard plate 2, thereby facilitating the formation of heat dissipation airflow; and combined with the assembly cavity formed above, it increases the space for the circulation flow of heat dissipation airflow, thereby facilitating the formation of a larger and faster fluid flow; thus, it can effectively improve the heat dissipation speed and efficiency, and ensure the orderly progress of heat dissipation; in addition, it also improves the convenience of assembly and the stability of the structure by assembling the inner body with other components of the radiator (such as the housing or motor).

[0034] Specifically, in some implementations, such as Figure 1 As shown, one end of the assembly cavity 5 extends through the thickness direction of the first protective plate 1; the other end of the assembly cavity 5 does not extend through the thickness direction of the second protective plate 2 and the inner mounting body 3. This structure, with the assembly cavity 5 being open at one end and closed at the other, allows airflow to be gathered from one end and transported to the airflow cavity 6 during rotation; thus forming a larger and faster airflow, which is beneficial to improving heat dissipation speed and efficiency.

[0035] Specifically, in some implementations, such as Figure 1 and 2 As shown, the width of the inner opening 62 of the airflow cavity 6 near the inner mounting body 3 is smaller than the width of the outer opening 61 of the airflow cavity 6 away from the inner mounting body 3. During rotation, the airflow enters the inner opening 62 from the opening end of the assembly cavity 5 and is then discharged from the outer opening 6. Therefore, this structure, through the airflow cavity 6 with its small inner dimension and large outer dimension, can quickly form a larger and faster flow of fluid, and can discharge it in an orderly and stable manner from the outer opening 6, thereby improving heat dissipation speed and efficiency.

[0036] Specifically, in some implementations, such as Figure 1 and 2As shown, the first protective plate 1 has a hollow structure; and a first mounting groove 11 is provided on the end face of the first protective plate 1 away from the inner guide body 4. The first mounting groove 11 is an annular groove. This structure, through the first mounting groove 11, can effectively reduce the overall weight and also ensure the stability of the overall structure, improving efficiency.

[0037] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the second guard plate 2 has a hollow structure; and the second guard plate 2 includes a supporting outer ring plate 23, a supporting middle ring plate 22, and a supporting inner ring plate 21 that are sequentially stacked along the length direction; one end face of the supporting middle ring plate 22 is connected to the guide inner body 4; the other end face of the supporting middle ring plate 22 away from the guide inner body 4 is provided with at least one second mounting groove 221; the inner mounting body 3 is connected to the inner side of the supporting inner ring plate 21 away from the supporting middle ring plate 22. In some embodiments, such as... Figure 3 As shown, there are thirteen second mounting grooves 221, which are equidistantly spaced; and the number of inner guide bodies 4 corresponds to the number of second mounting grooves 221. That is, the inner guide bodies 4 are located inside the second mounting grooves 221. This structure ensures the installation stability of the inner guide bodies 4 and effectively reduces the weight of the inner guide bodies 4, thereby ensuring the stability of the overall structure and improving efficiency.

[0038] Specifically, in some implementations, such as Figure 1 and 2 As shown in Figure 3, the inner mounting body 3 includes a flat main plate 31, an annular side plate 32, and a limiting protrusion 33. The flat main plate 31 is connected to the interior of the annular side plate 32, and a mounting cavity 301 is provided between the flat main plate 31 and the annular side plate 32. The open end of the annular side plate 32 is connected to the second protective plate 2 (the inner ring plate 21 of the middle support). The limiting protrusion 33 is disposed inside the mounting cavity 301. The limiting protrusion 33 has a mounting hole 333 communicating with the mounting cavity 301. The flat main plate 31 and the annular side plate 32 form an H-shaped or U-shaped structure. This structure, through the synergistic effect of the flat main plate 31 and the annular side plate 32, helps to improve the assembly stability between the flat main plate 31 and the annular side plate 32 and the heat sink housing or motor.

[0039] Specifically, in some implementations, such as Figure 3 and 4As shown, the limiting protrusion 33 includes a mounting post 331 and a reinforcing protrusion 332; the flat main plate 31 has a limiting groove 302 on its inner surface facing the mounting cavity 301; the mounting post 331 is connected to the inside of the limiting groove 302; one end of the reinforcing protrusion 332 is connected to the outer surface of the mounting post 331; the other end of the reinforcing protrusion 332 is connected to the inner wall of the limiting groove 302; the mounting hole 333 is provided through one end of the mounting post 331 in the thickness direction.

[0040] In some implementation methods, such as Figure 4 As shown, the mounting post 331 includes an inner post 3311 and an outer post 3312; the inner post 3311 is disposed inside the outer post 3312; the mounting hole 333 is disposed inside the inner post 3311; and the height of the inner post 3311 is greater than the height of the outer post 3312; one end of the reinforcing protrusion 332 is connected to the outer surface of the outer post 3312. That is, the inner post 3311 and the outer post 3312 form a stepped structure to ensure the stability of the assembly. Further, as... Figure 4 As shown, the mounting post 331 includes a first connecting block 3313; one end of the first connecting block 3313 is connected to the outer surface of the outer post 3312; the other end of the first connecting block 3313 is connected to the reinforcing protrusion 332 to further improve the stability of the structure.

[0041] In some implementation methods, such as Figure 4 As shown, the reinforcing protrusion 332 includes a second connecting block 3321 and a reinforcing ring block 3322; the reinforcing ring block 3322 is sleeved on the other side of the first connecting block 3313; and the reinforcing ring block 3322 is connected to the flat main board 31; one end of the second connecting block 3321 is connected to the outer surface of the reinforcing ring block 3322; the other end of the second connecting block 3321 is connected to the inside of the limiting groove 302; so as to further improve the stability of the structure.

[0042] Specifically, in some implementations, such as Figure 1 and 2 As shown, the inner flow guide 4 includes at least one finned plate 41; one end face of each finned plate 41 is connected to the first guard plate 1; the other end face of each finned plate 41 is connected to the second guard plate 2; and an airflow cavity 6 is formed between two adjacent finned plates 41 and between the first guard plate 1 and the second guard plate 2; and each airflow cavity 6 is connected to the assembly cavity 5. This structure forms multiple airflow cavities 6 between multiple finned plates 41 and between the first guard plate 1 and the second guard plate 2, thereby realizing multiple heat dissipation airflows, resulting in a larger and faster fluid flow, which is beneficial to improving heat dissipation speed and efficiency.

[0043] Specifically, in some implementations, such as Figure 2 , 3As shown in Figure 5, the finned plate 41 includes a straight section 411 and an arc-shaped section 412; one end of the arc-shaped section 412 is connected to the straight section 411; the other end of the arc-shaped section 412 is arc-shaped and faces the inner mounting body 3; and the two opposite end faces of the straight section 411 are respectively connected to the first guard plate 1 and the second guard plate 2; one end face of the arc-shaped section 412 is connected to the first guard plate 1; the arc-shaped section 412 is located on the inner side of the second guard plate 2. The straight section 411 and the arc-shaped section 412 are integrally formed. This structure uses the arc-shaped section 412 to quickly generate a higher-speed airflow during rotation; and uses the straight section 411 to ensure the uniformity, stability, and smoothness of the generated airflow discharge. Furthermore, the straight sections 411 in adjacent finned plates 41 are arranged in parallel; the arc-shaped sections 412 in adjacent finned plates 41 are also arranged in parallel; to ensure the uniformity of the airflow discharge generated by each airflow cavity 6; and to improve the stability and speed of heat dissipation. Furthermore, the width of the inner opening 62 located between two adjacent arc-shaped segments 412 is smaller than the width of the outer opening 61 located between two adjacent straight segments 411; this is to facilitate the formation of a larger and faster airflow, and to improve the heat dissipation speed and efficiency.

Since this radiator adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
