【産業上の利用分野】本発明は、冷却装置に関する。 The present invention relates to relates to a cooling apparatus.

【0002】 [0002]

【従来の技術】冷却装置として、冷却を必要とする物体の周囲に冷却液を供給して冷却する構造のものがある。 2. Description of the Related Art As a cooling device, there is a structure for cooling by supplying a cooling liquid to the surrounding objects that require cooling.
このような冷却装置としては、例えば、図5に示すように円筒形状の冷却すべき物体(以下「被冷却物体」という)1の両端近傍に環状の端板2、2を外嵌して全周に亘り溶着し、被冷却物体1の外側に同心的に配置した外筒3の両端をこれらの端板2、2の外周縁に全周に亘り溶着し、更に、外筒3に穿設された2つの孔に夫々口金4、5の各一端を嵌合して全周に亘り溶着固定し、被冷却物体1の外側に直接同心的にボックス構造の冷却室(ジャケット)6を形成した構造のものがある。 Such cooling devices, for example, fitted around the end plate 2 and 2 of the annular cooling to be an object of cylindrical shape (hereinafter referred to as "the cooled object") to the vicinity of both ends of 1, as shown in FIG. 5 all It welded over the periphery, welded over the ends of the outer tube 3 which is arranged concentrically on the outside of the cooling object 1 the entire circumference on the outer peripheral edge of the end plate 2 and 2, further formed in the outer tube 3 have been fitted each end of each die 4,5 welded and fixed over the entire periphery in the two holes to form a cooling chamber (jacket) 6 directly concentrically box structure outside of the cooling substance 1 there is a thing of the structure. なお、 It should be noted that,
被冷却物体1、外筒3、端板2、2及び口金4、5等は、例えば、炭素鋼等の鉄部材により形成されている。 The cooled object 1, the outer tube 3, the end plates 2,2 and the mouthpiece 4, 5, etc., for example, it is formed by iron member such as carbon steel.

【0003】そして、一方の口金4から冷却室6に冷却液を供給し、他方の口金5から当該冷却室6内の冷却液を排出させ、被冷却物体1から発生される熱を冷却液で熱交換して、当該被冷却物体1を直接冷却する。 [0003] Then, by supplying a coolant into the cooling chamber 6 from one of the base 4, the other of the base 5 by discharging the cooling liquid in the cooling chamber 6, the heat generated from the cooling object 1 with a cooling fluid and heat exchange to cool the object to be cooled object 1 directly.

【0004】 [0004]

【発明が解決しようとする課題】しかしながら、上記構造の冷却装置は、長い年月使用し続けた場合、冷却液中の不純物が冷却室6内で凝縮して、壁面に厚くこびりついたり、或いは冷却液自体が熱による劣化を起こし、冷却室6内で固体化して壁面に厚くこびりつくため、冷却液の流れる断面積が極めて小さくなり、冷却に必要な流量を確保することができなくなる。 [SUMMARY OF THE INVENTION However, the cooling device of the above structure, when continued for many years used, impurities in the coolant is condensed in the cooling chamber 6, or caked thick wall, or cooled cause degradation liquid itself by heat, since caking thick wall and solidified by a cooling chamber 6, the cross-sectional area of ​​flow of the coolant is extremely small, it becomes impossible to secure a flow rate required for cooling. この結果、冷却機能が低下し、冷却を必要とする装置の運転を停止せざるを得なくなることがあるまた、冷却室6を解体し、内部のスケールを除去するにしても、狭い現場での解体、スケールの除去、再溶接等の作業は、極めて困難であり、実質的には冷却を必要とする装置そのものを更新するしか手段がないという極めて不経済な問題があった。 As a result, the cooling function is reduced, the cooling may be forced to stop the operation of devices requiring also dismantling cooling chamber 6, even if the removing internal scale, in a narrow site dismantling, removal of the scale, the work of re-welding or the like is very difficult, in effect there is a very uneconomical problem that there is only a means to update the device itself require cooling.

【0005】また、上記構造の冷却装置は、被冷却物体1に端板2、2、外筒3、口金4、5等の部材を溶接して構成した構造のボックス構造であるために、特に、溶接部において溶接部材同士や、冷却液、当該冷却液に含まれる空気等により、局部的な電解腐食を生じやすく、 [0005] The cooling device of the above construction, the end plate 2,2 in the cooled object 1, the outer tube 3, to be box structure structure in which the welding member such as a cap 4, especially , and welding members to each other in the welding portion, the cooling fluid, the air or the like contained in the cooling liquid, prone to localized galvanic corrosion,
場合によっては、冷却を必要とする装置の内部に、冷却液が洩れ出して装置の運転に支障を来す虞がある等の問題があった。 Optionally, the interior of the device requiring cooling, there was a problem such that there is a possibility that hinder the operation of the cooling liquid is leaked device.

【0006】また、被冷却物体が高温で、内部に炭素材等を使用した炉とされ、冷却液に水が使用された場合に、洩れ出した水が炉内に侵入すると、水と炭素材とが反応して急速な減耗を起こしたり、一度に多量の水が炉内に侵入した場合には水蒸気爆発を起こす可能性がある等の問題もある。 Furthermore, in the cooled object is high temperature, is a furnace using carbon material or the like therein, when water is used for cooling liquid, the leaked water from entering the furnace, water and carbon material DOO react or cause rapid depletion, there is also a problem that is likely to cause steam explosion when a large amount of water enters into the furnace at a time. この発明は、上述の点に鑑みてなされたもので、冷却能力を長期間に亘り確保することを可能とすると共に、保全性及び操業性の向上を図るようにした冷却装置を提供することを目的とする。 The present invention has been made in view of the above, along with making it possible to ensure over the cooling capacity in a long period of time, to provide the so improve the integrity and operability cooler for the purpose.

【0007】 [0007]
