The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
First embodiment
Referring to fig. 1, in the present embodiment, a chassis 100 is provided, the chassis 100 includes a guiding structure 1 for changing an air flow, and the guiding structure 1 for changing the air flow is installed in a chassis body (not shown).
The guiding structure for changing the wind flow comprises a wind scooper body 10 and a circuit board 20, wherein the wind scooper body 10 is installed on the circuit board 20. It is understood that the wind scooper body 10 may be installed at other positions for guiding the cooling wind flow.
The air guide cover comprises an air guide cover body 10, and is characterized in that a flow resistance sheet 11 is installed on the air guide cover body 10, an expansion card slot 21 is formed in the circuit board 20, the expansion card slot 21 is arranged in the air guide cover body 10, and the flow resistance sheet 11 is used for being matched with the expansion card slot 21 in the circuit board 20.
When the expansion card slot 21 is not provided with an expansion card 22, the flow resistance sheet 11 is used for blocking the flow of cooling wind from passing through the expansion card slot 21.
When the expansion card slot 21 is inserted into the expansion card 22, the flow resisting sheet 11 is pushed to a predetermined height by the expansion card 22.
In a preferred embodiment, the choke plate 11 is fitted to the expresscard slot 21 for better fit. Referring to fig. 2, the wind scooper body 10 includes an upper edge plate 12. Further, the upper edge plates 12 are disposed on two opposite sides of the wind scooper body 10.
The upper edge plate 12 is not aligned with the top end of the wind scooper body 10. The upper edge plate 12 is closer to the circuit board 20 than the top end of the wind scooper body 10.
The circuit board 20 is provided with a plurality of expansion card slots 21, and the air guiding cover body 10 is provided with flow resistance pieces 11 corresponding to the expansion card slots 21.
Further, the flow resistance sheet 11 is mounted on the upper edge plate 12.
A plurality of the expansion card slots 21 are arranged in parallel on the circuit board 20.
Referring to fig. 3, the flow blocking piece includes a boss 111, and when the expansion cards 22 are installed in the expansion card slots 21, the expansion cards 22 push the flow blocking piece 11 to a predetermined height.
Referring to fig. 4, when the expansion cards 22 are installed in a plurality of the expansion card slots 21, one expansion card slot 21 is not installed with the expansion card 22. The flow resistance sheet 11 moves towards the expansion card slot 21, and the flow resistance sheet 11 can automatically fall down and is abutted against the upper edge plate 12 through the boss 111. The choke sheet 11 and the expansion card slot 21 form a closed state. When the cooling air flows, the expansion card slot 21 without the expansion card 22 can also hold the cooling air flow at a low level, so that the cooling air flow is prevented from passing through the expansion card slot 21 of the jack. Cooling air flows through the gaps between the expansion card slots 21, and heat generated by the expansion card 22 is carried away.
Second embodiment
The second embodiment is substantially the same as the first embodiment in structure, and is different in that when the flow resistance sheet 11 is mounted on the upper edge plate 12, one end of the flow resistance sheet 11 is rotatably connected to the upper edge plate 12 of the wind scooper body 10 through a first connecting member 121, and the other end of the flow resistance sheet 11 is a free end.
Referring to fig. 5, when the expansion cards 22 are installed in the expansion card slots 21, the flow blocking piece 11 rotates counterclockwise through the first connecting member 121, and the free end of the flow blocking piece 11 is pushed to another predetermined height by the expansion cards 22.
Referring to fig. 6, when the expansion cards 22 are installed in a plurality of the expansion card slots 21, one expansion card slot 21 is not installed with the expansion card 22. The free end of the flow resistance sheet 11 automatically falls into the expansion card slot 21 along the clockwise direction and abuts against the expansion card slot 21. When wind flows, the flow resistance sheet 11 abuts against the expansion card slot 21 to block the wind flow.
Third embodiment
The third embodiment is substantially the same as the first and second embodiments in structure, except that the flow resistance sheet 11 is provided with a through hole 112, and the flow resistance sheet 11 is movably connected to the upper edge plate 12 of the wind scooper body 10 through a second connecting member 122.
Referring to fig. 7, when the expansion cards 22 are installed in the expansion card slots 21, the second connecting member 122 moves in the through hole 112, the flow blocking piece 11 is pushed upward by the expansion cards 22 to a predetermined height, but the flow blocking piece 11 does not pass through the upper edge plate 12.
Referring to fig. 8, when the expansion cards 22 are installed in a plurality of the expansion card slots 21, one expansion card slot 21 is not installed with the expansion card 22. The choke plate 11 moves downward and forms a closed state with the expansion card slot 21.
In the above embodiment, the expansion card 22 is a memory card. It is understood that the expansion card 22 may be replaced with other components. The flow resistance sheet 11 may be attached to not only the upper edge plate 12 but also the flow resistance sheet 11 when the other portion of the wind scooper body 10 corresponds to the expresscard slot 21. The attachment of the flow resistance sheet 11 is not limited to the attachment in the above-described embodiment, and may be replaced with an attachment having the same effect or function.
In summary, the guiding structure 1 for changing the air flow provided in the above embodiment prevents the cooling air flow from directly passing through the expansion card slot 21 by installing the flow resistance sheet 11. Meanwhile, the flow resistance sheet 11 is directly arranged on the guide structure 1 for changing the wind flow, so that the loss of the flow resistance sheet 11 is avoided. The operation is simple, and the flow resistance sheet 11 is synchronously installed while the guide structure 1 for changing the wind flow is installed.
In addition, those skilled in the art should recognize that the foregoing embodiments are illustrative only, and not limiting, and that appropriate changes and modifications can be made without departing from the spirit and scope of the invention as defined by the appended claims.
