Description

Heat-pipe radiating apparatus

[technical field]

The utility model is about a kind of heat-pipe radiating apparatus, refers in particular to a kind of effectively heat-pipe radiating apparatus of cooling electronic components.

[background technology]

Be accompanied by the constantly development of electronic information industry, the running frequency of electronic component (particularly CPU) and speed are in continuous lifting.Yet the heat that high-frequency high-speed will make electronic component produce is more and more, and temperature is also more and more higher, and the performance when the electronic component operation in serious threat in order to ensure the normal operation of electronic component energy, must in time be discharged a large amount of heats that electronic component produced.

The traditional heat-dissipating device, as No. the 89214786th, 89213022, Taiwan patent application etc., these patents include a radiator, and this radiator comprises a heat dissipation base and is located at radiating fin on this base that this heat dissipation base is the entity metal.Yet along with the CPU volume is more and more littler, its heat that sends is also more concentrated, because be confined to the heat transfer property of metal, the heat of heat dissipation base center often too concentrate can't effectively be passed to heat abstractor around, and radiating rate is slow, has a strong impact on the integral heat sink effect, makes the decreased performance of CPU, can't significance arithmetic, even burn.

There is heat abstractor that the dealer uses as shown in Figure 1 in addition.This heat abstractor 10 comprises that two heating panels 12, some radiating fins 14 and two that is sticked on heating panel 12 are located in the C type heat pipe 16 on the heating panel 12.This heat pipe 16 is by the heat-conducting glue bonding or is welded on the heating panel 12.The heat transferred that CPU produces is delivered to heat rapidly on the heating panel 12 of far-end by heat pipe 16 to the heating panel 12 that joins with it simultaneously, by radiating fin 14 heat is dispersed into around the heat abstractor again, reaches the purpose of cooling CPU.Yet heat pipe 16 need be located in the hole of heat dissipation base 12, very inconvenience when heat pipe 16 welding or gluing; And the bending segment of heat pipe 16 does not have radiating fin 14 auxiliary heat dissipations, and its radiating efficiency should improve.The patent similar to above-mentioned technical characterictic has People's Republic of China's patent 98202990.X number and United States Patent (USP) the 6th, 394,175 B1 numbers.

[summary of the invention]

The purpose of this utility model is to provide the heat-pipe radiating apparatus of a kind of simple and convenient assembly, rapid heat dissipation.

The purpose of this utility model realizes by following technical proposal: the utility model heat-pipe radiating apparatus comprises some U type heat pipes, a pedestal, biside plate, the first radiating fin group and the second radiating fin group.This heat pipe has horizontal segment and vertical section.Offer semicircular notch on this pedestal, the horizontal segment of this heat pipe can be fitted in this notch.This biside plate is perpendicular to pedestal, and each side plate inboard all offers the semicircular notch that cooperates with this heat pipe vertical section.The first radiating fin group vertically is sticked on this pedestal; The second radiating fin group and the first radiating fin group are perpendicular, are sticked in the inboard of side plate; And these radiating fins are equipped with the breach that matches with heat pipe.The fan of an assistance heat radiation can be installed in the side of these radiating fins.

Because pedestal of the present utility model and biside plate offer semicircular notch, make heat pipe can convenient welding or gluing in notch; U type heat pipe horizontal segment is provided with some radiating fins vertical with pedestal, and its vertical section is provided with some radiating fins parallel with pedestal, make the heat of heat pipe to disperse by two groups of radiating fins, and because the bang path of heat on radiating fin be shorter, thus heat can effectively be dissipated into rapidly heat-pipe radiating apparatus around; Thereby the utility model heat-pipe radiating apparatus has the advantage of simple and convenient assembly, rapid heat dissipation.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

See also Fig. 2 and Fig. 3, the utility model heat-pipe radiating apparatus comprises some U type heat pipes 20, a pedestal 40, biside plate 60, the first radiating fin group 80 and the second radiating fin group 90.Can install the fan 30 of an assistance heat radiation in the side of these radiating fins.

This U type heat pipe 20 can transmit heat rapidly, has a horizontal segment 22 and two vertical sections 24, general one-tenth vacuum state in it, and be sealed with hydraulic fluid.

The one side of this pedestal 40 is close to heater element (figure does not show), and another side offers some semicircular notch 42, and these notches 42 match with the horizontal segment 22 of heat pipe 20, can heat pipe 20 be fixed on the pedestal 40 by modes such as welding or gluings.Some radiating fins extend vertically upward from pedestal 40, form the first radiating fin group 80.These radiating fins offer the breach 82 that matches with heat pipe 20.

These side plates 60 and pedestal 40 vertical settings, each side plate 60 inboard is equipped with the semicircular notch 62 that matches with heat pipe 20 vertical sections 24, and heat pipe 20 vertical sections 24 also can combine by modes such as welding or gluings with side plate 60.Each side plate 60 outside also is provided with a supporting part 64, is used for support fastener (figure does not show) so that whole heat-pipe radiating apparatus is close to the heater element surface.These supporting part 64 outer rims upwards bend out a catch 66, to prevent the slippage of fastener.60 of biside plates, some radiating fins are provided with perpendicular to side plate 60 and form the second radiating fin group 90, these radiating fins are fitted on the side plate 60, and each radiating fin is provided with the breach 92 that cooperates with heat pipe 20, and the first radiating fin group 80 is vertical mutually with the second radiating fin group 90.

This radiator fan 30 can be installed in the side of these radiating fins, carries out forced-convection heat transfer, improves radiating efficiency.

During heater element work, the heat transferred of its generation is to pedestal 40, and the part heat is dispersed rapidly by the first radiating fin group 80, because the bang path of heat on the first radiating fin group 80 is shorter, so its heat radiation is more effective; A part of heat transferred is to heat pipe 20 horizontal segments 22 simultaneously, the vaporization of being heated of hydraulic fluids in the heat pipe 20, thereby heat transferred is arrived heat pipe 20 vertical sections 24, around simultaneously heat being dispersed into by the side plate 60 and the second radiating fin group 90 this moment, the gaseous state hydraulic fluid heat release condensation of vertical section 24, be back to heat pipe 20 horizontal segments 22, thereby around the heat that effectively heater element is produced is dispersed into.

Assembling for convenience, the heat pipe of the U type heat pipe 20 also available L types of the utility model heat-pipe radiating apparatus is replaced.
