Embodiment

Refer to Fig. 3, the preferred embodiments of electronic equipment 200 of the present invention comprises a casing 201, and this casing 201 comprises two relative sidewalls 202, relative one first end wall 204 and one second end wall 205, a circuit board 207 and some hard disks 208.The middle part of this circuit board 207 is provided with a central processing unit 207a and some memory bar 207b, and the both sides of this circuit board 207 are respectively equipped with some expansion card 207c.This first end wall 204 and the second end wall 205 are offered respectively some air vents 209.In present embodiment, electronic equipment 200 is a server.

Electronic equipment 200 also comprises that one first dividing plate 30 of interval and parallel the first end wall 204 and the second end wall 205 and a second partition 40, some the first fans 50, some the second fans 60 and are vertically set on the wind scooper 80 between second partition 40 and the second end wall 205.This first dividing plate 30 and contiguous this first end wall 204 of second partition 40 are fixed between two side 202.Between this first dividing plate 30 and second partition 40, form a space 35.Corresponding these first fans 50 of this first dividing plate 30 are offered some air vents 32.These hard disks 208 are located between this first end wall 204 and the first dividing plate 30.These first fans 50 are fixed on the middle part of this second partition 40 and over against wind scooper 80.These the second fans 60 are oppositely fixed on the two ends of this second partition 40, make the air intake opposite direction of the first fan 50 and the second fan 60.Corresponding the first fan 50 of this second partition 40 and the second fan 60 offer air vent.Corresponding the first fan 50 of this wind scooper 80 is installed between this second partition 40 and the second end wall 205.This wind scooper 80 forms a first passage 82, and this central processing unit 207a and memory bar 207b are contained in this first passage 82.Between this wind scooper 80 and two side 202, form respectively a second channel 84, expansion card 207c is contained in respectively in second channel 84.

During use, these first fans 50 suck the distinguished and admirable air vent 209 from the first end wall 204 in electronic equipment 200, after the distinguished and admirable hard disk 208 of flowing through, from the air vent 32 of the first dividing plate 30, enter space 35, after the first fan 50, the first passage 82 through wind scooper 80 is discharged from the middle part air vent 209 of the second end wall 205 again.These second fans 60 air vent 209 at the distinguished and admirable two ends from the second end wall 205 is sucked and this expansion card 207c that flows through after enter in space 35, through the first fan 50, enter in first passage 82.

Compared with prior art, because the first fan 50 on the second partition 40 of this electronic equipment is contrary with the wind direction that the second fan 60 produces, these second fans 60 enter in space 35 after guiding expansion card 207c into distinguished and admirable, are conducive to expansion card 207c to dispel the heat; Meanwhile, increase and enter the air quantity in space 35, be beneficial to the heat radiation of central processing unit 207a and memory bar 207b.

Refer to Fig. 4, the emulation heat distribution plan from electronic equipment of the present invention when 35 degrees Celsius of the environment temperatures can learn, the temperature of expansion card 207c, central processing unit 207a and memory bar 207b all declines to some extent.In the situation that not changing electronic equipment 200 inner structure, only the second fan 60 is oppositely installed, can be made the distinguished and admirable heat radiation of these electronic equipment 200 inside balanced, improving radiating effect.
