【発明の詳細な説明】 〔産業上の利用分野〕 本発明は各種機器、その部品、各種材料等の対高温特
性、対低温特性等を試験するための液槽式の高温環境試
験装置や低温環境試験装置、前記物品の対熱衝撃特性を
試験する液槽式の冷熱衝撃試験装置その他の液槽式環境
試験装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a liquid tank type high temperature environment tester for testing the high temperature characteristics, low temperature characteristics, etc. of various devices, parts thereof, various materials, etc. The present invention relates to an environmental test device, a liquid tank type thermal shock test device for testing the thermal shock resistance of the article, and other liquid tank type environmental test devices.
液槽式環境試験装置においては、液槽内の液体が所定
試験温度に維持され、該液槽内に試料が所定時間浸漬さ
れる。In the liquid tank type environmental test device, the liquid in the liquid tank is maintained at a predetermined test temperature, and the sample is immersed in the liquid tank for a predetermined time.
この試験用液体には、一般的には、電気絶縁性が良好
である、沸点が所望高温試験温度より高いものや凝固点
が所望低温試験温度より低いものを入手し易い等の理由
から、フッ素系不活性流体が採用されることが多い。This test liquid is generally a fluorine-based liquid because it has good electrical insulation properties, and has a boiling point higher than the desired high temperature test temperature and a freezing point lower than the desired low temperature test temperature. Inert fluids are often employed.
例えば液槽式冷熱衝撃試験装置においては、フッ素系
不活性流体などの液体を液槽内に貯蔵し、該槽内液体温
度を所望の高温および低温に維持し、該高温液および低
温液に試料を交互に浸漬することにより、試料に急激な
温度変化を与えている。For example, in a liquid tank type thermal shock test device, a liquid such as a fluorine-based inert fluid is stored in a liquid tank, the liquid temperature in the tank is maintained at a desired high temperature and a low temperature, and the high temperature liquid and the low temperature liquid are sampled. The sample is subjected to a rapid temperature change by being alternately immersed.
このような冷熱衝撃試験において、低温液に浸漬され
ている試料が該低温液から摘出されると、該液体は試料
に付着して常温域へ持ち出されるから急激に蒸発する。
また、低温液が付着した試料をそのまま高温液に浸漬す
れば、該付着液はさらに加熱され蒸発する。In such a thermal shock test, when a sample immersed in a low-temperature liquid is extracted from the low-temperature liquid, the liquid adheres to the sample and is taken out to a normal temperature range, so that the liquid rapidly evaporates.
If the sample to which the low temperature liquid adheres is immersed in the high temperature liquid as it is, the adhered liquid is further heated and evaporated.
また、高温液については、例えば沸点が175℃の液を1
50〜160℃に加熱し、その温度で試験を実施するので、
高温液槽から常に活発に該液が蒸発する。As for the high temperature liquid, for example, a liquid with a boiling point of 175 ° C
Since it is heated to 50-160 ℃ and the test is conducted at that temperature,
The liquid constantly evaporates actively from the high temperature liquid tank.
このように液槽内の液に起因して発生した蒸気を装置
外へ流出させると、槽内液体の量が減少し、試験が続行
できなくなる。また、試験用の液体は高価であるため、
装置の運転コストがきわめて高くなる。さらに、装置周
囲を試験用液体やその蒸気で汚染するという問題もあ
る。When the vapor generated due to the liquid in the liquid tank is caused to flow out of the apparatus in this way, the amount of the liquid in the tank decreases and the test cannot be continued. Also, because the test liquid is expensive,
The operating costs of the device are very high. Further, there is a problem that the area around the device is contaminated with the test liquid or its vapor.
このような問題を解決する手段の代表例として、液槽
開口部を蒸気飛散防止用の箱体で覆い、該箱体内におい
て試料を液槽に出し入れできるようにするとともに該箱
体内気体を循環させて液槽内液体に起因する蒸気を冷凍
回路の冷却器で凝縮回収するものが知られている。As a typical example of means for solving such a problem, the opening of the liquid tank is covered with a box for preventing vapor scattering, so that the sample can be taken in and out of the liquid tank in the box and the gas inside the box is circulated. It is known that the vapor resulting from the liquid in the liquid tank is condensed and recovered by the cooler of the refrigeration circuit.
しかしながらこの従来解決手段によると、液槽開口部
を覆う蒸気飛散防止用箱体内の冷却器能力をあまり大き
くすることができない。何故なら冷却器能力が大き過ぎ
ると、該箱体の温度が装置周辺の温度（周囲温度）より
低くなって箱体壁等に結露するからである。従って冷却
器はそのような結露が発生しない程度に箱体内温度を低
下させる程度の小さな冷却器とされるか、または前記結
露が発生する程に箱体温度を低下させないように、冷却
器をオン／オフさせなければならない。However, according to this conventional solving means, it is not possible to increase the capacity of the cooler in the vapor scattering prevention box that covers the opening of the liquid tank. This is because if the cooler capacity is too large, the temperature of the box body becomes lower than the temperature around the apparatus (ambient temperature), and dew condensation occurs on the box wall or the like. Therefore, the cooler is a small cooler that lowers the temperature inside the box to the extent that such condensation does not occur, or the cooler is turned on so that the temperature inside the box does not drop so much that condensation occurs. / I have to turn it off.
従って蒸気を液化回収するに充分な冷却能力を提供す
ることができないという問題がある。Therefore, there is a problem that it is impossible to provide a sufficient cooling capacity for liquefying and recovering vapor.
また、蒸気を液化回収するに充分な冷却能力を有する
冷却器を使用するときには、箱体気体温度を周期温度と
同等に保持するために箱体内に加熱源を備え、箱体内気
体温度を一定に維持しなければならない。そしてこのた
めには電気ヒータ、ソリッドステートリレー、温度調節
器、温度センサ等の装備が必要となり装置コストは大幅
に上昇するという問題がある。When using a cooler having sufficient cooling capacity to liquefy and recover vapor, a heating source is provided in the box to keep the box gas temperature at the same level as the cycle temperature, and the box gas temperature is kept constant. Must be maintained. For this purpose, an electric heater, a solid state relay, a temperature controller, a temperature sensor, and the like are required, which causes a problem that the cost of the apparatus is significantly increased.
そこで本発明の目的は、液槽開口部が蒸気飛散防止用
箱体で覆われ、該箱体内試料を液槽に出し入れできるよ

槽式環境試験装置を提供することにある。Therefore, an object of the present invention is that the liquid tank opening is covered with a vapor scattering prevention box, and the sample in the box is configured to be taken in and out of the liquid tank, and is caused by the liquid in the liquid tank in the box. Is a liquid tank type environmental test device configured to condense and recover the steam to be condensed and recovered in a cooler of a refrigeration circuit, and can sufficiently cool and condense and recover the steam, and yet to separate an electric heater or the like. To provide a liquid tank type environmental test device capable of maintaining the gas temperature in the box at a temperature at which condensation does not occur on the box wall or the like without the need to add a heat source or turn on / off the cooler. It is in.
