Description
Technical field
The present invention relates to the portable information equipment of notebook computer etc., do not pass to the portable information equipment that the user prevents misoperation thereby relate in particular to the inner heat that takes place.
Background technology
The heat transferred that produces of the inside of portable information equipment such as notebook computer is to the surface of crust of the device in recent years, after the temperature on crust of the device surface rose, the heat of device user's the health and the part of said apparatus case surface Long contact time can make the device user feel under the weather.The pyrotoxin of computer inside mainly is that the surface temperature of CPU, power supply, especially CPU reaches above about 100 ℃ temperature.
In this case, as nearest technology, have and between heat generating part of installing inside and crust of the device, use thermal insulation material to carry out heat insulation technical scheme.
Such as, the notebook computer that Japanese patent laid-open 11-202978 communique discloses has: carry out heat insulation thermal insulation material to installing between inner heat generating part and the crust of the device; Be located at the heat sink at the display part back side; With the heating tube of the inner heat transferred that is produced of device to heating plate; Structure with blow vent.By using the technology that Japanese patent laid-open 11-202978 communique is disclosed, the temperature that can suppress the body case surface to a certain extent rises.
But the heat-insulating property of thermal insulation material is in relatively poor occasion, and the inhibition effect of heat that is passed to the crust of the device surface is just poor, needs to increase the thickness of thermal insulation material in order to obtain effect.On the other hand, the thin typeization of notebook computer expectation recently, lightweight, therefore, thermal insulation material also needs small-sized, light weight.
And the inner heat that produces of device produces very bad influence to the outside extended terminal of random-access memory (ram) card and LAN (Local Area Network) (LAN) card etc., and action might lead to errors.
General thermal insulation material uses foams such as corpus fibrosum such as glass fibre and urethane foam.But, in order to improve the thermal insulation of these thermal insulation materials, needing to increase the thickness of thermal insulation material, the space of filling thermal insulation material is restricted, and saves space and the occasion of effective utilization in space is inapplicable at needs.
The a kind of measure that addresses this problem is to adopt the vacuum heat insulation materials that is made of the core that keeps the space, the cladding material that space and outer air bound is disconnected.Core generally uses the foams of dusty material, fibrous material, connectionization etc., but requires more high performance vacuum heat insulation materials in recent years.
For this reason, be purpose with the high performance of core, the Jap.P. spy opens and proposed feature in the clear 60-33479 communique is the vacuum heat insulation materials that powder formed carbon is made homogeneously dispersed state in the pearlite powder.In addition, having disclosed powder formed carbon is that a kind of carbon black is the vacuum heat insulation materials of feature, and carbon black is evenly disperseed, and heat-insulating property can improve 20% under top condition.
In addition, the spy opens in the clear 61-36595 communique, has disclosed carbon dust is dispersed in to be the vacuum heat insulation materials of feature in the various powder.Among the embodiment, by being even carbon blacks in the silicon dioxide of 100nm at the single-particle diameter, thereby heat-insulating property improves 20% under top condition.
In addition, in the special fair 8-20032 communique, disclosed a kind of use by the flue gas (Japanese: the vacuum heat insulation materials of the micropowder of Chan Shenging ヒ ュ one system) that takes place in the Antaciron production.In addition, disclose this micropowder and contained the above vacuum heat insulation materials of carbon 1wt% at least.This thermal insulation material can improve heat-insulating property 23%.
But, pearlite, spy in the special public clear 60-33479 communique opens in the flue gas that takes place in the silicon dioxide, the Antaciron production in the special fair 8-20032 communique of the single-particle diameter 100nm in the clear 61-36595 communique to be contained in the specification of powder formed carbon and carbon, and the flue gas that pearlite, the silicon dioxide of single-particle diameter 100nm, the Antaciron that uses as mother metal takes place in producing does not show the excellent especially performance as the core of vacuum heat insulation materials.Therefore, even highly contain the specification of powder formed carbon and carbon, compare with other vacuum heat insulation materials, its heat-insulating property does not have tremendous raising yet, and the effect of improving of heat-insulating property rests on about 20%.
In addition, use in the specification of carbon black as powder formed carbon, carbon black is generally the coaly product that oil component obtains through rough burning, owing to contain the organic gas of this impurity, so produce gas through after a while, therefore exist the problem that interior pressure increases, heat-insulating property worsens of vacuum heat insulation materials.In addition, reactions such as reactivity base such as the terminal carbonyl that exists of the molecular structure of carbon black and airborne moisture still produce gas through after a while, and the interior pressure of same vacuum heat insulation materials increases, the heat-insulating property deterioration.
Core generally uses porous body, can roughly be divided into being communicated with foam, fiber-like, powdery type.
Wherein, the powdery type vacuum heat insulation materials uses SiO 2 powder more.Use the vacuum heat insulation materials of SiO 2 powder, its initial stage heat-insulating property is not as fiber-like, but its permanent heat-insulating property is outstanding.
But because be powder, it is poor to pretend the industry property, encloses inner bag because of powder and uses, so abnormal shapeization is difficult.In addition, powder disperses when discarded, and operating environment is poor.In order to improve this situation the trial that silicon dioxide is made to body is arranged also.But it is difficult that SiO 2 powder is formed porous body separately, use various bonding agents.
Such as, in the special fair 4-46348 communique of Jap.P., disclose a kind of vacuum heat insulation materials that has used the formed body that wet silicon dioxide and fiber-reinforced material are mixed, compress.
It is a structure like this: after the occasion that temperature difference is big between the wall that uses wet silicon dioxide and fiber-reinforced material and vacuum heat insulation materials is added mixed radiation and prevented material, carry out compression molding and be formed into body.
In addition, in the special fair 5-66341 communique, provide a kind of vacuum heat insulation materials that dry type silicon dioxide, wet silicon dioxide, fiber-reinforced material is mixed the formed body after disperseing, compressing that used.
It is a structure like this: the easiness as the stamping press of advantage as the low heat conductivity of advantage and wet silicon dioxide of dry type silicon dioxide is replenished mutually, and composite fibre strengthening material and the formed body that forms.
But, be very difficult with the independent shaping of SiO 2 powder.
In addition, as the fair 4-46348 communique of spy, even wet silicon dioxide is mixed stirring, carries out compression molding and obtain the occasion of formed body with fibrous material, with this formed body one take will fall apart in the hand fragile like that.In addition, powder dances in the air, and operation and the property handled are poor.In addition, such as making cylindrical shape, but because fragile just falling apart is no flexible, therefore suitable place is restricted at once.
In addition, as the fair 5-66341 communique of spy, even wanting wet silicon dioxide, dry type silicon dioxide, fibrous material mixed stirs, carry out compression molding and obtain the occasion of formed body, because of sneaking into wet silicon dioxide, so be difficult for becoming formed body, be highly brittle.In addition, powder dances in the air, and is no flexible.
