Description

Heat abstractor in the system

Technical field

The present invention relates to a kind of heat abstractor, particularly a kind of heat abstractor that utilizes white effort law to dispel the heat.

Background technology

Along with scientific-technical progress, people also increase for the dependence of various electronic equipments, and notebook computer especially is because of the convenience that it had causes demand in recent years to heighten.Yet the electronic apparatus system inner member can produce high heat, if high thermal conductance can't be gone out internal system, causes internal system overheated easily.

Be example with the notebook computer and please refer to Fig. 1 that existing general heat abstractor 1 comprises a fan 11, one fixtures 12, a plurality of radiating fin 13, one pedestals 14 and at least one heat pipe 15.Fixture 12 is a housing, and has an opening.Fan 11 spiral shells are located on the fixture 12; A plurality of radiating fins 13 are arranged on the pedestal 14, and pedestal 14 is linked to fixture 12; One end of heat pipe 15 is linked to a heat radiator 2, and the other end is linked to pedestal 14, but and the material of heat pipe be the material of heat conduction, as metal etc.Heat radiator 2 is linked to a pyrotoxin.

After electronic equipment started running, the pyrotoxin of electronic apparatus system inside can produce high heat along with the running of equipment.The high heat utilization heat-conduction principle that pyrotoxin produced is transmitted to radiating fin 13 on pedestal 14 and the pedestal 14 via heat radiator 2 with heat pipe 15.Fan 11 runnings on the fixture 12 can produce air-flow, and the opening of airflow passes fixture and radiating fin 13, thereby are able to by air-flow the high torrid zone that pyrotoxin produced be gone out internal system.

Notebook computer main pyrotoxin be central processing unit (Central Processing Unit, CPU) and video drawing array (Video Graphics Array, VGA) etc., though the installing of radiating fin can increase area of dissipation, also can increase percentage of open area in addition, even be in the tube chamber of heat pipe, to add thermal conductance liquid, in the hope of increasing the speed of heat radiation, but with existing heat abstractor, can't be with hot-air that CPU, VGA and other less important pyrotoxin far away produced guiding system effectively, thereby cause the higher system temperature easily.

As mentioned above, how to provide a kind of can be fast and the heat abstractor of heat radiation effectively be one of current important topic in fact.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art and defective, heat abstractor in a kind of system is provided, it can be effectively and the high heat of guiding system inside apace.

For reaching above-mentioned purpose, the invention provides heat abstractor in a kind of system, it utilizes white effort law that the high thermal conductance of electronic apparatus system inside is gone out.

In heat abstractor of the present invention, comprise: a fan is arranged at this electronic equipment; An and guide duct, it is a heat conductor and is a hollow tube, this guide duct comprises one first end and one second end, wherein this first end is close to this fan, this guide duct part near this second end contacts with one first pyrotoxin, when this fan rotated generation one air-flow, the high heat that this first pyrotoxin is produced was along with this air-flow, and this second end is derived toward this first end certainly.

Embodiment

Following with reference to the heat abstractor of relevant drawings explanation according to preferred embodiment of the present invention, wherein components identical will be illustrated with identical reference marks.

Please refer to shown in Figure 2ly, according to the heat abstractor 3 of the embodiment of the invention, it is arranged in the electronic equipment, comprises a fan 31 and a guide duct 32.Fan 31 is arranged in the electronic equipment; Guide duct 32 is a hollow tube, comprises one first end 321 and one second end 322, wherein first end, 321 contiguous fan 31, the second ends 322 contiguous one first pyrotoxins 4.

First pyrotoxin 4 is an electronic component or is an integrated circuit.The opening surface of second end 322 is to first pyrotoxin 4, and the bore of opening is more than or equal to the guide duct caliber.

Heat abstractor 3 more comprises a fixture 33, one pedestals 34 and a plurality of radiating fin 35.Fixture 33 is a housing, and has an opening 331, the first ends 321 and be linked to opening 331.Fan 31 spiral shells are located on the fixture 33.Pedestal 34 is linked to fixture 33, and radiating fin 35 is arranged on the pedestal 34.When fan 31 rotates, rotate the airflow passes radiating fin 35 that is produced and export 332.

When fan 31 rotates, can produce an air-flow, and, produce lower pressure arround mobile gas can cause, and the fast more pressure of flow velocity is low more according to the white law of making great efforts; Simultaneously, first pyrotoxin 4 produces high temperature, and high temperature causes that air produces the high-pressure phenomena of thermal expansion.Form a pressure differential between high pressure and the low pressure, the height that the pyrotoxin 4 of winning is produced is warm along with air-flow, be guided toward first end 321 from second end 322 and the 3rd end 323, rotate the air-flow that is produced by fan 31 again and the high thermal conductance of being guided is gone out internal system through opening 331 and radiating fin 35.In addition,, therefore can strengthen the area of heat radiation, accelerate the speed of heat radiation owing in the airflow passes approach, be provided with radiating fin 35.

The material of guide duct 32 can be metal or macromolecular material; Guide duct 32 can be a heat conductor.Please refer to shown in Figure 3ly, when guide duct 32 is heat conductor, partly can contact near the guide duct 32 of second end 322, and the opening of second end 322 is in the face of first pyrotoxin 4 with first pyrotoxin 4; In addition, the guide duct 32 of close first end 321 partly also can contact with fixture 33 and pedestal 34, so guide duct 32 can utilize heat-conduction principle and the white law of making great efforts that the high thermal conductance that pyrotoxin produced is gone out simultaneously.

Please refer to shown in Figure 4ly, guide duct 32 can comprise that more one the 3rd end, 323, the three ends 323 are near one second pyrotoxins 5.Guide duct 32 is a Y-shaped.

The electronic equipment of another embodiment of the present invention comprises a casing, a fan and a guide duct.Guide duct is a hollow tube, comprises one first end and one second end, and wherein first end is close to fan, contiguous one first pyrotoxin of second end.Electronic equipment more comprises a fixture, a pedestal and a plurality of radiating fin.Fixture is essentially a housing with opening, and first end is linked to fixture, and the fan spiral shell is located on the fixture, and pedestal is linked to fixture, and radiating fin is arranged on the pedestal.When fan rotated, fan rotated the opening and the radiating fin of the airflow passes fixture that is produced.Because the heat abstractor in the present embodiment, its structure, set-up mode and effect are all identical with mentioned person in the aforementioned heat abstractor 3, do not repeat them here; Only, in the present embodiment, because as previously mentioned, guide duct is a hollow, and first end and the contiguous fan of second end and first pyrotoxin, when fan rotates the generation air-flow, the high heat that first pyrotoxin is produced is along with air-flow, derived toward first end from second end, therefore the hot-air of electronic apparatus system inside guiding system effectively can be avoided improving the internal system temperature.

The above only is an illustrative, but not is restricted.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the scope of claims its equivalent modifications of carrying out or change.
