Taiwan Patent No. M343367 discloses that the axial-flow fan is disposed at the center of the heat sink and the heat sink of the heat sink is arranged in a row so that the wind flow blown by the fan can be radiated from the inside to the outside. . Team leader I" seeks a sentence, showing an axial flow: the fan is placed on the side of the radiator, and - the word is fresh on the fresh 'to make the fan's wind flow from the side of the heat collector The other side.

The baffle has an inner surface facing the opening of the first track and an air inlet of the second channel, and is associated with the coffee. In view of the entrance of the recording hood, the fan blows into and out of the inlet of the first passage, and then enters the second passage via the guide of the deflector. The entrance and exit from its exit. Compared with the prior art, those first and second channels in the present creation constitute a "swivel air passage" such that the airflow blown by the fan can be highly utilized for the first heat sink and the second heat sink. Heat dissipation to achieve the goal of improving airflow utilization.

The first heat sink 12 and the second heat sinks 13 are arranged side by side on the bottom plate 1Q. The bottom plate 10, the first heat sink 12, and the second heat sink 13 can be made of a heat conductive metal material such as copper or copper. The bottom plate 1G, the first scatter 12, and the second heat sink 13 may be a body-molded structure. In another embodiment, after the first heat sink I2 and the second heat sink u form a predetermined shape, they are coupled to the bottom plate 10. The bonding method can be turned over by thermal conductive adhesive or soldered. The fan 2 is provided on the bottom plate 1G. The air hood 3 covers the heat sink and has a population 31, an outlet 32, and a baffle 3 〇. As shown in the second figure, each of the first passages 121 is substantially defined by every two first hot segments 12, each of which has an air inlet 121a and an outlet air: (4). Similarly, each of the second passages 131 is substantially defined by two fewer first heat dissipations 13 each of which has an air inlet 131a and an air outlet 131b. The air outlets (four) of the first passages 121 and the The lugs 131a of the second passage 131 are side by side 'and are both oriented in a first direction, that is, the inner surface of the baffle 30 facing the guide (five) 3. The second figure also indicates that the inlet 31 of the air duct 3 communicates with the air inlet 12U of the first passages 121. The fan 2 is located at the outlet 32 of the air hood 3 and the outlet 32 of the air duct 3 and the air outlet (10) of the second channel (3). The air deflector 31 of the hood 3 has an inner surface facing the first channel. The air outlet 121b of the (2) is spaced apart from the second channel 131 by a distance of M360552. The structure and arrangement of the above-mentioned components are such that the airflow blown by the fan 2 enters from the population ma. And grasping from the outlet 121b and then contacting the money flow sheet 3Q, the wind flow then enters the inlet 13la of the first passages 131 and exits from the outlet (3)b. In short, the second channel 121 and the second channel 131 obviously constitute a rotary air channel, so that the airflow from the mouth of the fan 2 flows through the first heat sinks n, that is, The second heat sink 13 enables the waste heat generated by the wafer 4 in the first figure to be quickly dissipated due to the operation. H'j skill*, because the above-mentioned rotary wind 2 of the original Wei Qingcheng makes the wind flow blown by the fan 2 can be highly utilized for the first dispersion of the first: the heat sink of the second and second heat sinks U, thereby achieving the improvement of the airflow The utilization rate of the heat samples u shown in the first and second figures is straight _, so that the air vents are directly passed through the air outlets n_21 _ the tuyere 121a air outlets (10), and the first passages (2) are directly connected to the air outlets thereof. The direction—the first Ασ121α and the opposite direction of the second channel 131 direction. In this direction, the second direction is such that the flow rate of the first-square two heat-cold::::: is improved. The first surface of the baffle includes a flat surface 31 having two opposite sides, and two inclined surfaces 32 extending from opposite sides of the flat surface w, respectively. The angle between the two inclined faces 32 and the flat face 31 is 2 to 9 degrees. With the guiding action provided by such a baffle 3, the noise is low and the flow is smooth. Further, the inner surface of the baffle 3 is formed into a concave curved surface, and the aforementioned effect is better. ~ In the examples shown in the first and second figures, wherein the first heat sinks η and the ', ', and the sheets 13 are not all of the same length, but are intentionally arranged to have a length to make the The position of the air outlet (4) of the first passage m and the air inlet 131a of the second passage 131 is gradually convex from the _ toward the towel. This not only allows the air outlets of the first passages 121 and the air inlets (3)a' of the second passages 131 to maintain a proper spacing of the air guides with the guide vanes 3G. In the exception of the third embodiment, the positions of the first channel (2) air outlet 121b and the air inlets 13la of the second channels are gradually reduced from the both sides toward the center. In the example shown in Figures 1 and 2, this will further improve the conductance. In the example shown in the fourth figure, the air guiding hood 3 is further provided with a plurality of guiding openings ^4' having the same shape as the deflector 3 (), and the total length is slightly shorter. The baffle 34 makes the flow guiding action of the air guiding hood 3 better. In the above examples, the air hood 3 also has a partitioning partition 33, which can define the air hood 3 _ portion as two spaces that can communicate with each other, wherein one M360552 is empty = cover the first - The heat sink 12, the other space will cover the second volume of the post..., the film (1) following the 4 Λ Λ 2 The wind muscles flowing through the first scorpion slab 12 降低 flow reduce the wind flow to the second The opportunity of the fins 13 can also reduce the chance of wind leakage to the first fins 12 as the wind swirls through the second fins u. In any case, anyone can get enough guidance from the description of the above examples and understand that the creation is indeed industrially useful, novel and progressive, and is submitted in accordance with the law.
