In an embodiment, a plurality of grooves are formed between the fins, and the air guiding structure further has a plurality of protrusions, wherein the protrusions are respectively engaged with the grooves.

In one embodiment, the protrusion and the groove are substantially the same in a first axial direction, and the first axis is perpendicular to the fin.

In one embodiment, the protrusion and the groove are substantially the same in a second axial direction, and the second axis is parallel to the fin.

In an embodiment, the cover body and the protruding portion are integrally formed.

Referring to FIG. 1A and FIG. 1B , the heat dissipation assembly 10 of the embodiment of the present invention mainly includes a heat dissipation module 100 and an air guiding structure 200 . The heat dissipation module 100 has a plurality of fins 100a, and a plurality of grooves 100b are formed between the adjacent fins 100a. The air guiding structure 200 can be used to guide the airflow (as indicated by the arrow in FIG. 1B). It mainly comprises a cover 202, wherein the cover 202 is composed of a top cover 202a and two side plates 202b substantially perpendicular to the top cover 202a, and forms a U-shaped cross section. In addition, the two side plates 202b are substantially parallel to the fins 100a of the heat dissipation module 100, and a protruding portion 204 is respectively extended on the same side of the two side plates 202b, wherein the protruding portion 204 can be in phase with the side plate 202b. The joint is bent (as indicated by the arrow direction in Figure 1A).

In the present embodiment, the cover body 202 and the protruding portion 204 are formed by bending the integrally formed polyester film (mylar).

Then, as shown in FIG. 1A, FIG. 1B, and FIG. 2, the air guiding structure 200 of the present embodiment can have substantially the same size as the heat dissipation module 100 in a first axial direction D1. The first axial direction D1 is perpendicular to the fin 100a of the heat dissipation module 100. Accordingly, when the air guiding structure 200 is combined with the heat dissipation module 100 (as shown in FIG. 1B), the air guiding structure 200 is bent inward. The protrusion 204 is detachable The grooves 100b formed between the outermost two adjacent fins 100a of the thermal module 100 are engaged with each other (as shown in FIGS. 1B and 2).

It should be noted that, in this embodiment, the protruding portion 204 of the air guiding structure 200 can be fitted into the groove 100b between the fins 100a on the heat dissipation module 100, and the protruding portion 204 and the groove 100b are A first axial direction D1 or a second axial direction D2 (parallel to the fins 100a of the heat dissipation module 100) has substantially the same size, wherein the first axial direction D1 and the second axial direction D2 are perpendicular to a flow direction D3 (as indicated by the direction of the arrow in Figure 1B). In this way, through the limitation of the fins 100a, the air guiding structure 200 and the heat dissipation module 100 can be well fixed in the first axial direction D1 and the second axial direction D2 and the assembly of the heat dissipation assembly 10 can be completed.

Furthermore, the heat dissipating component 10 can be disposed in a computer system to remove thermal energy generated by a particular electronic component of the computer system during operation. The heat dissipation module 100 of the heat dissipation component 10 can be coupled to the specific electronic component, and the air guiding structure 200 of the heat dissipation component 10 can be combined with the heat dissipation module 100 to form an air inlet and an air outlet. A heat dissipation module 100 is disposed in the air inlet, and a fan (not shown) for providing forced convection is disposed in the air outlet.

In the embodiment, the air guiding structure 200 is engaged with the groove 100b of the heat dissipation module 100 through the two protruding portions 204. However, it should be understood that the wind guide structure 200 may actually include only one protrusion 204 to be combined with the single groove 100b of the heat dissipation module 100.

3A is a schematic view showing the air guiding structure 200 of the heat dissipating assembly 10 according to another embodiment of the present invention. An opening 202c is formed on each of the two sides of the air guiding structure 200, and the two protruding portions 204 of the air guiding structure 200 are respectively outwardly facing outward. The side bends (as indicated by the arrow direction in FIG. 3A) pass through the opening 202c to engage with the recess 100b between the fins 100a of the heat dissipation module 100 (see FIG. 3B). It should be noted that, since the protruding portion 204 of the air guiding structure 200 can be firmly engaged with the groove 100b of the heat dissipation module 100, the air guiding structure of the heat dissipating component 10 caused by the external force collision can be avoided. The 200 and the heat dissipation module 100 are separated from each other.
