The first top plate 311 extends from a side opposite to the first side plate 3丨3 by a first connecting edge 315. A plurality of first card slots 3151 are formed on the first connecting edge 315 corresponding to the first fastening block 3321, and a first card hole 31 53 is formed corresponding to the first fastening elastic plate 3323. The third cover 35 has a third top plate 351 and a third side plate 353. The ................. The third top plate 351 and the third side plate 353 opposite to the g side of the second extension edge 355. The second connecting block 355 corresponding to the second fastening block "^ opens a plurality of second card slots 3551, corresponding to the second fastening elastic plate 3353 to open a second card hole 3553. Referring to Figure 4, when assembled, the The first fastening block 3321 and the second fastening block 3351 of the second cover 33 are respectively engaged with the first cover 31 and the third slot 315 and the second slot 3 5 51 of the first cover 31 and the third cover. The first cover body 31 and the third cover body 35 are moved in the first direction relative to the second cover body 31. The first fastening elastic piece 3323 and the second fastening elastic piece 3353 of the second cover body 33 are respectively The first cover body 31 and the first cover hole 3153 and 3553 of the third cover body 35 are engaged with each other. The stop end of the first fastening elastic piece 3323 "buts against the hole edge of the first card hole 3153. The stopping end 3 3 5 5 of the second fastening elastic piece 3353 is abutted against the hole edge of the second clamping hole 3 5 5 3 , thereby limiting the first cover body 31 and the third cover body 35 relative to the second cover body 31 moves in a second direction opposite to the _th direction. The first connection side of the first military body 31 is punishable by the form number A0101, page 6 / page 16 0982052610-0 201110868 Ο [0022] 002 [0022] Three shells 35 The second connecting edges 315 are respectively abutted against the step faces 333 and 336 of the second cover 33. Thus, the first cover 31, the second cover 33, and the third cover 35 can be connected together. The air hood 30 is formed together. The first top plate 311 of the first cover 31 and the third top plate 351 of the third cover 35 are respectively connected to the two sides of the second cover 33, thereby forming the air hood 30. The top side cover 313 of the first cover body 31 and the third side plate 351 of the third cover body 35 form two side walls of the air guiding cover 30. The top cover and the two side walls of the air guiding cover 30 The air guiding passages 39 on the second cover 33 of the air guiding cover 30 are engaged with the fixing protrusions 151 on the heat dissipating device 15 in a corresponding manner. Therefore, the second cover 33 is fixed to the heat sink 15 to assist the heat dissipation of the CPU. The first cover 31 and the third cover 35 are respectively disposed above the memory strips 17 on both sides to support the memory. Referring to FIG. 5, when it is necessary to disassemble the memory strips 17 on both sides of the electronic device 10, the corresponding cover 31 or 35 can be removed. For example, for example. When the first cover 31 is removed, the first fastening elastic piece 3323 on the second cover 33 is pressed to disengage the blocking end 3325 from the first opening 3153 of the first cover 31. The first cover 31 is detached from the second cover 33 by dragging the first cover 31 in the second direction. The plurality of large electronic devices 10 are used by the combined air hood 30 of the present invention. When the electronic components are dissipated, if it is necessary to operate some of the electronic components, it is not necessary to take out the entire air hood 30, and only the cover corresponding to some of the electronic components needs to be removed.
