Wherein, the fan has a fan frame, and the fan frame forms an air outlet on the side. The slabs are arranged in parallel, and are arranged at the air outlet of the fan frame to form a rectangular block group, and the (4) group abuts the frame to position the group. However, the fan frame of the fan is usually integrally formed by die casting or injection molding, that is, a body-molded piece or an injection molded part, and a chamfer is formed on the frame during the manufacturing process. If the group of linings, the right-angled edge of the group will interfere with the chamfering edge, so that the fin group cannot be closely abutted with the fan frame, and a gap is formed between the fin group and the fan frame, which not only makes the fin group inconvenient to be assembled, but also assembles Difficult, and the airflow generated by the fan will flow out from the gap, affecting the utilization of the fan airflow, and ultimately affecting the heat dissipation efficiency of the heat dissipation module. In order to solve the above problem, the interference chamfer must be removed before the fan and the film group are assembled. The commonly used methods in the industry are mainly manual frustration or CNC (Computerized Numerical Control) processing. However, it is difficult to remove the chamfer by hand and it will affect the appearance. For CNC machining, 1315178 is required to increase the process and increase the production cost. SUMMARY OF THE INVENTION The following is a specific embodiment to illustrate a heat dissipation module that is convenient to position and assemble. The heat dissipation module includes a fin set and a fan. The fan includes a frame and a fan wheel set in the fan frame. One side of the fan frame is provided with an air outlet, and the fin set is disposed at the air outlet. At the office. The fan frame extends outwardly at the air outlet to form at least one baffle. The groove forms a groove at the junction with the fan frame. Compared with the prior art, since the groove is formed at the joint between the baffle and the fan frame, the interference between the limb and the wind can be avoided, and the assembly and positioning are convenient. [Embodiment] Hereinafter, the present invention will be further described with reference to the accompanying drawings.

The fan frame 60 is integrally formed by injection molding, and the frame 60 includes a main plate 61, a bottom plate 62, and a side plate connected between the WE 61 and the reference 62. The top plate 61, the bottom plate 62 and the side plate 64 together form a housing fan set body, and the fan wheel set 68 is used to generate airflow. The top plate 61 is disposed in parallel with the bottom plate 62, and is disposed on the upper and lower sides of the fan wheel set 68. The top plate 61 and the bottom plate are in a central position, that is, a circular air inlet 65 is formed at the position of the fan wheel set 68. . The side plate 64 defines an air outlet 66 on one side of the fan frame 60, and extends outwardly from the side plate 64 at both ends of the air outlet 66 to form a first baffle 6 and a first 1315178 baffle 63b. The air outlet 66 The airflow generated by the fan 6 is blown from the air outlet 66 toward the fin group 4 to dissipate heat to the fin group 4, perpendicular to the air inlet 65. The bottom end of the baffle 63a 63b forms a notch 67 through which the heat pipe 2 is disposed, adjacent to one side of the bottom plate a. Referring to Fig. 3, the top plate 61 is formed on the side of the air outlet 66 to form an abutment surface 610 which is perpendicular to the shutters 63a, 631). The two baffles 63a, 63b are disposed in parallel with each other, and a space (not labeled) for receiving the fin group 4 is formed therebetween, and an inner surface 630 is formed on one side of each of the baffles 63a, 63b facing the fin group 4. . The top end of the inner surface 63 is intersected with the abutting surface 610 of the top plate 61, and a recess 69 is formed at the boundary between each of the baffles 63a or (4) and the top.

The groove 69 is substantially a square shape, and the groove 69 is arbitrary. The two interface faces form a curved inverted corner R at the boundary thereof, and the inner surface 630 and the abutting surface 61 are planar in a position facing the fin group 4. The Korean chip group 4 is formed by arranging a plurality of heat radiating fins 4 which are parallel to each other. The fin group 4 is disposed in a space between the two baffles 63a, 63b of the fan 6, and is laterally located at the air outlet 66 of the fan frame 60. As shown in FIG. 4, each of the heat dissipation fins 4A includes a body portion 42, a flow guiding portion 43 projecting from the body portion 42, and flanges 44, 48 formed at the top end and the bottom end of the body portion 42, respectively. The flanges 44, 48 of the adjacent heat-dissipating fins 40 abut each other, wherein the upper end flanges 44 abut against each other to form a top surface of the fin group 4, and the lower end flanges abut against each other to form a bottom surface of the fin group 4' An air flow passage 47 extending in the direction of the flanges 44, 48 is formed between the adjacent heat dissipation tabs 40. The flow guiding portion 43 includes two protrusions 43a at the upper end of the body portion 42 and two protrusions 43b at the lower end of the body portion 42. The protrusions 43a, 1315178 43b are inclined along the traveling direction of the airflow to form two sets of eight-shaped structures, respectively. The body portion 42 of the heat dissipation sheet 40 is disposed on both sides of the axis of symmetry XX of the airflow traveling direction. Wherein the protrusions 43a are close to the top surface of the fin group 4, and the protrusions 43b are close to the bottom surface of the fin group 4, and each of the two protrusions 4 having a figure-eight shape, or 4%, is formed at a distance close to one end of the flanges 44 or 48.

Each of the protrusions includes a parallel surface 430a that is larger than the body portion 42 and a side wall 43b that connects the body portion 42 and the parallel surface φ 430a. The side wall 430b will be the upper end of the parallel surface 43〇a, the lower end and the direction away from the airflow. One end is connected to the main body portion 42 of the heat dissipating fin 4, and the female one protrusion 43a or 43b forms an opening 45 on one side facing the airflow traveling direction for the airflow to flow through the opening 45 between the heat dissipating fins 4'. Referring to FIG. 1 'the bottom surface of each of the heat dissipation fins 4 对应 is formed with a recess 46 downwardly corresponding to each protrusion 43a or 4%, and the flow guiding portion 43 can increase the convection effect between the airflow and the fin group 4. In addition, the flow guiding portion 43 can act as a turbulence to destroy the laminar flow underlayer formed on the surface of the heat dissipating fin 4〇. • The heat spreader 1 is attached to a heat-generating electronic component (not shown). The heat pipe 2 serves as a bridge for heat transfer between the heat-generating electronic component and the fin group 4, and has an evaporation end 21 in thermal contact with the heat equalizing plate 1 and a notch 67 which is disposed at the lower end of the two baffles 63a, 63b.
