Embodiment

See also Fig. 1,2, the electronic installation 100 of one embodiment of the invention for example is a notebook computer, and it mainly is made up of a body 20 and a display 23.As shown in Figure 2, be provided with the drain pan 10 of an activity in addition below the body 20 of electronic installation, wherein drain pan 10 can articulate with body 20 mutually by a pivot 11, makes that drain pan 10 can be with respect to body 20 rotations.

Please continue to consult Fig. 2, aforementioned body 20 has an interconnective loam cake 21 and a back of the body cover 22, when drain pan 10 is in a make-position with respect to body 20, and drain pan 10 and loam cake 21 almost parallels, and the back of the body covered 22 meetings and interconnect with drain pan 10 this moment.As seen from Figure 2, between the loam cake 21 of body 20 and drain pan 10, can form the gas channel P of hollow, the fan 40 that is arranged at body 20 inside can be with outside air from the first louvre H1 inspiration body 20, then can arrive the dorsal part (shown in the direction of arrow among Fig. 2) of body 20 via the gas channel P between loam cake 21 and the drain pan 10, cover second on 22 via drain pan 10 and the back of the body in regular turn more at last, the 3rd louvre H2, H3 and discharge body 20, as seen from Figure 2, but be formed with the open region that an air feed stream passes through between drain pan 10 and the body 20, and this open region has one first width A1 on vertical direction.

What need to specify is, is provided with a driver element 30 in addition in aforementioned body 20 inside, and aforementioned driver element 30 can be step motor or servo motor, and driver element 30 can drive drain pan 10 with respect to body 20 rotations by gear or rack mechanism.In the present embodiment, the control circuit (not shown) that aforementioned driver element 30 electrically connects in the body 20 can be controlled driver element 30 by control circuit and drive drain pan 10 with respect to body 20 rotations.

When electronic installation is in the use state, the electronic component that is positioned at body 20 inside can produce a large amount of heat, yet it is too high and influence system effectiveness for fear of the temperature of aforementioned electronic element, can drive drain pan 10 by driver element 30 in the present embodiment and rotate to an open site (as shown in Figure 3) with respect to body 20, so as to improving radiating efficiency.By among Fig. 3 as can be seen, when drain pan 10 rotates to the open site with respect to body 20, the 3rd louvre H3 that the second louvre H2 on the drain pan 10 and the back of the body cover on 22 becomes released state by original overlap condition, can significantly increase the area of open region thus, that is drain pan 10 is increased to the second width A2 with body 20 formed open regions by the first width A1 originally, and then can improve radiating efficiency.
