【発明が解決しようとする課題】
しかしながら、ＣＰＵ２の発熱量が増えるにつれて、ＬＣＤパネル５への熱漏洩量が多くなることは避けられず、ＬＣＤパネル５の熱的耐久性を阻害するなどの問題があった。特にＣＰＵ２の消費電力が５０Ｗを超えるような処理能力の高いノート型パーソナルコンピューターを設計すると、ＬＣＤパネル５の温度が６５℃を超え、ＬＣＤパネル５の色が黒ずむ問題があった。
【０００８】
本発明は、処理能力の高いノート型パーソナルコンピューターを提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記の目的を達成するために、本発明の請求項１に記載のノート型パーソナルコンピューターの発明は、上蓋に、ＬＣＤパネル、ＣＰＵなどの発熱体の温度を下げるための放熱板、および前記ＬＣＤパネルと前記放熱板との間仕切り部に真空断熱材を配設したものである。
【００１０】
【発明の実施の形態】
以下、本発明の真空断熱材を用いたノート型パーソナルコンピューターの実施の形態にについて説明する。
【００１１】
（実施の形態１）
図１は本発明のノート型パーソナルコンピューターの実施の形態１の斜視図である。図２は同実施の形態のノート型パーソナルコンピューターの上蓋部の要部断面図である。
【００１２】
図１，図２において、ノート型パーソナルコンピューター９は、発熱体であるＣＰＵ２に水冷ジャケット１０を近接し、タンク１１にためられた冷却水をポンプ３を使って、水冷ジャケット１０に循環させ、吸熱した水を配管を通じて上蓋４の放熱板６に導いている。
【００１３】
このとき、放熱板６は、面積の取れるＬＣＤパネル５の裏面に配設し、上蓋４から放熱させている。放熱板６とＬＣＤパネル５の間仕切り部１２には、厚み３ｍｍの真空断熱材１３を配設している。
【００１４】
真空断熱材１３は、ガラス繊維を高密度に固形化した物を芯材として、金属−プラスチックスラミネートフィルムで被い、内部を減圧して封止したものである。熱伝導率は、０．００５Ｗ／ｍＫで、７０℃の放熱板６の熱を遮断し、ＬＣＤパネル５の温度が５５℃に低下するまで断熱している。
【００１５】
この結果、放熱板６からの熱を断熱し、耐熱性の弱いＬＣＤパネル５へ影響抑制しているため、ＬＣＤパネル５の品質を安定化し、問題が起こらないのである。特に、処理能力を上げるために、消費電力量の大きなＣＰＵ２を採用するにつれて、発熱量が増加するが、このときのＬＣＤパネル５への熱的問題がなくなり、高性能のノート型パーソナルコンピューター９を提供することが可能となる。
【００１６】
【発明の効果】
以上説明したように本発明の請求項１に記載の発明では、上蓋に、ＬＣＤパネル、ＣＰＵなどの発熱体の温度を下げるための放熱板、および前記ＬＣＤパネルと前記放熱板との間仕切り部に真空断熱材を配設してなるノート型パーソナルコンピューターであるため、大容量のＣＰＵなどの発熱体を用いて高速処理化を行っても、増大した発熱量がＬＣＤパネルに影響せずに断熱できるため、ＬＣＤパネル画面の黒化を防ぎ、高性能のノート型パーソナルコンピューターを提供することが出来るのである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a notebook personal computer using a vacuum heat insulating material.
[0002]
[Prior art]
Since a notebook computer has a small and thin structure due to the characteristics of a product, a means for radiating heat generated from built-in electronic components and the like has been proposed (for example, see Non-Patent Document 1).
[0003]
An example of heat dissipation processing in a conventional notebook personal computer will be described with reference to FIGS.
[0004]
FIG. 3 is a perspective view of a conventional notebook personal computer. FIG. 4 is a cross-sectional view of a main part of an upper lid of a conventional notebook personal computer.
[0005]
3 and 4, heat generated from a heating element such as a CPU 2 built in the notebook personal computer 1 is conveyed by a pump 3 using water as a coolant, and is radiated on a rear surface of an LCD panel 5 of an upper cover 4. The plate 6 was radiating heat. The upper cover 4 was formed of a plastic frame 7, and the LCD panel 5 and the heat sink 6 were separated by a plastic partition 8 made of resin.
[0006]
[Non-patent document 1]
Hitachi, Ltd. FLORA270W Catalog [0007]
[Problems to be solved by the invention]
However, as the amount of heat generated by the CPU 2 increases, the amount of heat leakage to the LCD panel 5 is inevitably increased, and there is a problem that the thermal durability of the LCD panel 5 is hindered. In particular, when designing a notebook personal computer having a high processing capability such that the power consumption of the CPU 2 exceeds 50 W, the temperature of the LCD panel 5 exceeds 65 ° C., and the color of the LCD panel 5 becomes dark.
[0008]
An object of the present invention is to provide a notebook personal computer with high processing capability.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the invention of a notebook personal computer according to claim 1 of the present invention comprises a heat radiating plate for lowering the temperature of a heating element such as an LCD panel and a CPU on an upper lid; A vacuum heat insulating material is provided at a partition between the heat sink and the heat sink.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a notebook personal computer using the vacuum heat insulating material of the present invention will be described.
[0011]
(Embodiment 1)
FIG. 1 is a perspective view of a notebook personal computer according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view of a main part of the upper lid of the notebook personal computer of the embodiment.
[0012]
1 and 2, the notebook personal computer 9 has a water-cooling jacket 10 close to a CPU 2 as a heating element, and circulates cooling water accumulated in a tank 11 through the water-cooling jacket 10 by using a pump 3 to absorb heat. The drained water is guided to the heat radiating plate 6 of the upper lid 4 through a pipe.
[0013]
At this time, the heat radiating plate 6 is disposed on the rear surface of the LCD panel 5 having a large area, and radiates heat from the upper lid 4. A vacuum heat insulating material 13 having a thickness of 3 mm is provided in a partition 12 between the heat radiating plate 6 and the LCD panel 5.
[0014]
The vacuum heat insulating material 13 is obtained by using a material obtained by solidifying glass fibers at a high density as a core material, covering with a metal-plastic laminate film, and sealing the inside by reducing the pressure. The thermal conductivity is 0.005 W / mK, and the heat of the radiator plate 6 at 70 ° C. is cut off, and the LCD panel 5 is insulated until the temperature of the LCD panel 5 drops to 55 ° C.
[0015]
As a result, the heat from the heat radiating plate 6 is insulated and the influence on the LCD panel 5 having low heat resistance is suppressed, so that the quality of the LCD panel 5 is stabilized and no problem occurs. In particular, as the CPU 2 which consumes a large amount of power is employed to increase the processing capacity, the amount of heat generated increases. However, at this time, there is no thermal problem on the LCD panel 5 and the high-performance notebook personal computer 9 can be used. Can be provided.
[0016]
【The invention's effect】
As described above, in the invention according to claim 1 of the present invention, the upper cover has a heat sink for lowering the temperature of a heating element such as an LCD panel and a CPU, and a partition between the LCD panel and the heat sink. Because it is a notebook type personal computer with vacuum insulation material, even if high-speed processing is performed using a heating element such as a large-capacity CPU, the increased amount of heat can be insulated without affecting the LCD panel. Therefore, blackening of the LCD panel screen can be prevented, and a high-performance notebook personal computer can be provided.
