Embodiment
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Please refer to Fig. 1 to Fig. 3, electronic equipment 1 of the present invention comprises to be located at the heat-generating electronic elements 10 in the notebook computer and to be located at a heat radiation module 20 that is used in this notebook computer 10 heat radiations of this heat-generating electronic elements, and this heat radiation module 20 comprises a radiating fin group 21, be used for a centrifugal cutter 23 of this radiating fin group 21 heat radiations and connect a heat pipe 25 of this radiating fin group 21 and heat-generating electronic elements 10.
This centrifugal cutter 23 comprises flat loam cake 231, one a flat lower cover 232 and is located at a volute sidewall 233 between this loam cake 231 and the lower cover 232.This lower cover 232 is one-body molded by aluminium, plastic or other material with this sidewall 233, surrounds the containing space 234 that the rotor 230 of this centrifugal cutter 23 is accommodated in formation one between this loam cake 231, lower cover 232 and this sidewall 233.This loam cake 231 and lower cover 232 offer the first relative intake grill 235 and second intake grill 236 respectively in the position of respective rotor 230.This lower cover 232 is provided with a supporting portion 237 in the position of second intake grill 236, these supporting portion 237 support rotor 230 are rotated in this containing space 234 in the counterclockwise direction, produces the air-flow that is used for 10 heat radiations of this heat-generating electronic elements.
One side of this sidewall 233 is offered first exhaust outlet 238 of a lineal shape, and this radiating fin group 21 is located at this first exhaust outlet, 238 places, and is connected with the condensating section 251 of heat pipe 25.This sidewall 233 is parallel to the plate body 26 of lower cover 232 at the opposite side relative with this first exhaust outlet 238 to the direction horizontal-extending one away from this centrifugal cutter 23, and offers second a less exhaust outlet 239 at the position that is connected with sidewall 233 near this plate body 26.This plate body 26 is attached on this heat-generating electronic elements 10, and is connected with the evaporator section 253 of heat pipe 25, and the heat that this heat-generating electronic elements 10 produces is passed to radiating fin group 21 places via this heat pipe 25.This first exhaust outlet 238 is greater than this second exhaust outlet 239, make most of air-flow that centrifugal cutter 23 produces by first exhaust outlet 238 when radiating fin group 21 flows out, also there is the small part air-flow to flow out, directly blows to this heat-generating electronic elements 10 by this second exhaust outlet 239.In the present embodiment, centrifugal cutter 23 turns round in the counterclockwise direction, for making the air-flow that blows out by second exhaust outlet 239 directly blow to this heat-generating electronic elements 10, this second exhaust outlet 239 is located at the left side of this heat-generating electronic elements 10, and promptly this second exhaust outlet 239 is positioned at the place ahead of this heat-generating electronic elements 10 on the sense of rotation of centrifugal cutter 23.Similarly, under the situation that centrifugal cutter 23 turns round along clockwise direction, this second exhaust outlet 239 need be arranged at the right side of heat-generating electronic elements 10, directly blows to heat-generating electronic elements 10 to guarantee the air-flow that is blown out by second exhaust outlet 239.
This radiating fin group 21 have with the contacted upper surfaces 211 of the condensating section 251 of heat pipe 25 and with lower cover 232 contacted a lower surface 212 of centrifugal cutter 23, offer a groove 213 that extends along the length direction of radiating fin group 21 on the lower surface 212 of this radiating fin group 21, the lower cover 232 of this centrifugal cutter 23 in the position of first exhaust outlet 238 to should groove 213 protruding out the projection 241 of two long strips.When this radiating fin group 21 is mounted to first exhaust outlet, 238 places of this centrifugal cutter 23, this projection 241 is arranged in the set groove 213 of the lower surface 212 of this radiating fin group 21, prevents that radiating fin group 21 from skidding off this centrifugal cutter 23 along the direction perpendicular to projection 241.
As shown in Figure 4, during these heat radiation module 20 work, a part of heat transfer that heat pipe 25 produces heat-generating electronic elements 10 is to radiating fin group 21 places, it is outer and be distributed in the surrounding environment that the air-flow that blows out by means of first exhaust outlet 238 via this centrifugal cutter 23 blows out the casing of notebook computer with this part heat, forms first heat dissipation path; Simultaneously, the air-flow that other a part of heat that this heat-generating electronic elements 10 produces then blows out by means of second exhaust outlet 239 by centrifugal cutter 23 directly brushes and cools off, and forms second heat dissipation path.
This heat radiation module 20 dispels the heat to heat-generating electronic elements 10 by two heat dissipation path, compares with the existing heat radiation module that only has an exhaust outlet, and its heat dissipation is further improved; And this heat radiation module 20 is under the prerequisite of volume that does not increase notebook computer and weight, only can realize raising to heat dissipation by means of the mode of offering second exhaust outlet 239 at the sidewall 233 of centrifugal cutter 23, compare with the heat radiation module that improves heat dissipation by means of adding centrifugal cutter with existing, it has when promoting heat dispersion, need not to increase advantages such as cost, highly versatile.
