起きる機能障害から電子機器を保護していた。The present invention is applicable to electronic devices used outdoors [Prior art] For example, when electronic devices are used outdoors, the electronic devices are installed in a simple building (electronic device housing) such as a container. . This protects electronic equipment from malfunctions caused by heating due to direct sunlight.

われる。As a case for electronic equipment used outdoors, there is, for example, one described in Japanese Patent Application Laid-Open No. 59-219996. In this case for electronic equipment, the surface that easily receives sunlight is treated with a surface treatment that has a high light reflection coefficient to reflect sunlight.
Surfaces that are difficult to receive sunlight are treated with a surface treatment that has a low light reflection coefficient to radiate internal heat. Surface treatment is performed by painting, baking, chemical treatment, or machining.
ところで、上述した従来の電子機器用筺体にあっては、
例えば夏の炎天下での温度上昇を防止しようとすると、
反対に冬の低温下では温度が低すぎる等、環境に左右さ
れて電子機器が動作するために適切な雰囲気温度が確保
できないという問題点があった。By the way, in the conventional electronic device casing mentioned above,
For example, when trying to prevent temperature rise under the scorching summer sun,
On the other hand, there was a problem in that it was not possible to secure an appropriate ambient temperature because the electronic equipment operated depending on the environment, such as the temperature being too low in the low temperatures of winter.
本発明は、このような点にかんがみて創作されたもので
あり、電子機器に適切な雰囲気温度を確保するようにし
た電子機器用筺体を提供することを目的としている。The present invention was created in view of these points, and an object of the present invention is to provide a housing for an electronic device that ensures an appropriate ambient temperature for the electronic device.
本発明の電子機器用筺体は、内部に電子機器を収容し、
可逆熱変色性組成物によって表面処理を施す。The electronic device housing of the present invention accommodates an electronic device inside,
Surface treatment is performed with a reversible thermochromic composition.
この可逆熱変色性組成物については、例えば特公昭６０
−１５６６８号公報に記載されたものが知られている。Regarding this reversible thermochromic composition, for example,
The one described in Japanese Patent No.-15668 is known.
（作 用〕
電子機器用筺体の表面処理に可逆熱変色性組成物を使用
する。(Function) A reversible thermochromic composition is used for surface treatment of electronic device housings.
例えばこの熱変色性組成物は、温度が高くなれば光反射
係数が高くなり、温度が低くなれば光反射係数が低（な
る。電子機器用筺体の外部の温度が高くなると、表面の
光反射係数は高くなり光の吸収が減少するので内部の温
度上昇は低下する。For example, this thermochromic composition has a high light reflection coefficient when the temperature is high, and a low light reflection coefficient when the temperature is low. The coefficient increases and light absorption decreases, so the internal temperature rise decreases.
また、外部の温度が低くなれば、表面の光反射係数は低
くなり光の吸収がおこり内部の温度上昇が図られる。使
用する熱変色性組成物の光反射係数の変化は色の変化と
して知ることができる。Furthermore, when the outside temperature decreases, the light reflection coefficient of the surface decreases, light is absorbed, and the internal temperature increases. A change in the light reflection coefficient of the thermochromic composition used can be known as a change in color.
本発明にあっては、温度に応じて表面の色（光反射係数
）を変化させることにより、電子機器に適切な雰囲気温
度を確保することができる。In the present invention, by changing the color of the surface (light reflection coefficient) according to the temperature, it is possible to ensure an appropriate ambient temperature for the electronic device.
以下、図面に基づいて本発明の実施例について詳細に説
明する。Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
第１図は、本発明の一実施例における電子機器用筺体の
外観を示す。FIG. 1 shows the appearance of an electronic device casing in one embodiment of the present invention.
図において、本発明実施例の電子機器用筺体１１１の表
面には熱変色性組成物として例えば常温あるいは低温で
黒色であり、温度が上昇すれば白色に変色するものを選
択して一様に塗装を施す。In the figure, the surface of the electronic device casing 111 according to the embodiment of the present invention is uniformly coated with a thermochromic composition that is black at room temperature or low temperature and changes to white when the temperature rises. administer.
この電子機器用筺体１１１では、電子機器用筺体１１１
表面に太陽光が照射されて温度が上昇すれば、照射され
た該当箇所の塗料は熱変色を起こして白色になる。ここ
では変色する色として光反射係数が高い白色を選択して
いる。従って、変色後は照射される太陽光の多くが反射
され、熱の吸収が起こりにくくなり、電子機器用筺体１
１１内部の温度上昇を抑制することができる。In this electronic device housing 111, the electronic device housing 111
When the surface is irradiated with sunlight and its temperature rises, the paint in the irradiated area undergoes thermal discoloration and becomes white. Here, white, which has a high light reflection coefficient, is selected as the color that changes color. Therefore, after discoloration, much of the sunlight that is irradiated is reflected, making it difficult for heat to be absorbed.
11 can be suppressed from increasing in temperature.
使用する熱変色性組成物は可逆性を持ち、温度が常温に
戻れば白色から黒色に再び変色する。The thermochromic composition used has reversibility, and once the temperature returns to room temperature, the color changes from white to black again.
一方、冬のように屋外の温度が低い場合には、電子機器
用筺体の表面は黒色であり、黒色は光反射係数が低いた
め照射される太陽光を吸収して、電子機器用筺体１１１
内部の温度を上昇させる。On the other hand, when the outdoor temperature is low, such as in winter, the surface of the electronic device casing is black, and since black has a low light reflection coefficient, it absorbs the irradiated sunlight and the electronic device casing 111
Increase internal temperature.
上述したような熱変色性組成物の変色は、電子機器用筺
体１１１の表面のどこに太陽光が照射されても起こり得
る。この場合その部分のみが白色に変色して、電子機器
用筺体１１１内部の局部的な温度差を生じにくくする効
果がある。The above-mentioned discoloration of the thermochromic composition can occur no matter where on the surface of the electronic device housing 111 is irradiated with sunlight. In this case, only that portion changes color to white, which has the effect of making it difficult for local temperature differences to occur inside the electronic device housing 111.
また、高温時以外の電子機器用筺体１１１の表面を黒色
とすることで、内部の電子機器の放熱を効率よく外部に
放射する効果もある。Further, by making the surface of the electronic device housing 111 black except when the temperature is high, there is an effect of efficiently radiating heat from the electronic device inside to the outside.
このようにして、外部の温度に応じて表面の色（光反射
係数）が変化して温度の変化を抑制するので、電子機器
に適切な雰囲気温度を確保でき、収容する機材の動作の
信頼性を向上できる。In this way, the color of the surface (light reflection coefficient) changes depending on the external temperature, suppressing temperature changes, ensuring an appropriate ambient temperature for electronic equipment, and improving the reliability of the operation of the equipment contained in it. can be improved.
また、表面全体を熱変色組成物で塗装するため予め太陽
光の照射位置を予測する必要もない。この変色は太陽光
の照射位置と温度に応じて起こるため、空調設備が設置
できない無人の屋外設備（例えば通信の中継基地）等に
有効である。Furthermore, since the entire surface is coated with a thermochromic composition, there is no need to predict the irradiation position of sunlight in advance. This discoloration occurs depending on the position and temperature of sunlight, so it is effective for unmanned outdoor facilities (for example, communication relay bases) where air conditioning equipment cannot be installed.
なお、上述した本発明の実施例にあっては、電子機器用

ために使用する迷彩色を実現することもできる。In the above-described embodiments of the present invention, a thermochromic composition was applied to the surface of the electronic device housing to suppress internal temperature changes, but paints that change color in different colors (
It is also possible to create camouflage colors that are used to match nature, for example, by applying different paints (paints that are green at room temperature and change from green to black and from green to white as the temperature drops).
更に、本発明は本実施例に限られることはなく、各種の
変形態様があることは当業者であれば容易に推考できる
