とを発明の要旨とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a blower radiator that is connected to a blower outlet to cool discharged gas, and utilizes a flexible hose made of a thin, corrosion-resistant metal that can be bent freely. In addition, a plurality of axially extending hoses are provided to enable shape retention when the hose is spirally wound and inserted into a gas flow pipe, and to ensure a gas ventilation path on the outer and inner peripheries of the spirally wound flexible hose. The gist of the invention is that the number of supporters and sub-supporters are arranged.
ブロワーに於て、圧縮熱を帯有して吐出される

ーツブロワーはピストン式に比して容積効率が悪
く、圧力0.1Kg／cm2で約10℃の温度上昇があり、
３Kg／cm2で約300℃と圧縮吐出ガスの温度上昇が
著しい。 In blowers, it has already been implemented to connect a radiator for the purpose of cooling the compressed gas to the discharge port of the compressed gas which is discharged while carrying the heat of compression.
On the other hand, roots blowers that use roots-type rotors (two-shaft, three-shaft, etc.) have lower volumetric efficiency than piston-type blowers, and have a temperature rise of approximately 10℃ at a pressure of 0.1 kg/ cm2 .
At 3Kg/cm 2 , the temperature of the compressed discharge gas rises significantly to about 300℃.
他方ブロワー放熱装置には、圧縮排気管の軸方

Kg／cm2以下のブロワーにもそのまま使用されてい
る場合が多く、冷却能力が過剰でしかも大型にな
り、かつコスト高になつて経済的に不利である。 On the other hand, there are heat exchange systems for blower heat dissipation devices, such as one in which a large number of cold water pipes are installed parallel to the axial direction of the compression exhaust pipe, or one in which a serpentine cold water pipe is installed in the compression exhaust pipe. This is used for blowers in the high pressure range of ~20Kg/ cm2 , and this is
It is often used as is in blowers with a capacity of less than Kg/cm 2 , which is economically disadvantageous due to excessive cooling capacity, large size, and high cost.
然るに最近はドライ・クリーン・エヤーが食品

圧縮圧力が３Kg／cm2〜１Kg／cm2と比較的低く、し
かも僅かな油ミストの混入をも嫌うから、このよ
うな小型のブロワーに適した簡易な放熱器が要望
されている。 Recently, however, dry clean air has been widely used in the food industry, high-grade painting industry, etc., and these have relatively low compression pressures of 3Kg/cm 2 to 1Kg/cm 2 , and are also sensitive to even the slightest amount of oil mist. Therefore, there is a need for a simple heat sink suitable for such small blowers.
一般的な放熱器において、コイル形に形成した
冷水管を高熱ガスを通す円筒に内装した型式のも
のもある。かかるコイル形冷却管は管厚が大きい
銅製が多く、高価であり重量も大きいから小型ブ
ロワーの冷却器には適切でない。 Some common radiators include a coil-shaped cold water pipe inside a cylinder through which high-temperature gas passes. Such coil-shaped cooling pipes are often made of copper with a large pipe thickness, are expensive, and are heavy, so they are not suitable for use in coolers for small blowers.
本発明は上記の諸点を考慮して小型ブロワーに
適応するようにしたものである。 The present invention takes the above points into consideration and is adapted to small-sized blowers.

品である。 Inside the gas flow tube 4, there are pipes, porous pipes,
A large number of axial supports 7 made of rods, V-shaped steel, etc. are arranged in a ring shape at intervals in contact with the inner wall surface as shown in FIG. Since the flexible hose 8 can be bent freely, it is wound into a spiral shape and is fitted inwardly into the supporter 7 described above. The flexible hose 8 is a commercially available product made of extremely thin stainless steel with a thickness of approximately 0.4 to 0.6 mm, as shown in the cross-sectional view of FIG.

気体の撹拌混合作用を著しくする。 In the present invention, a water pipe is connected to the inlet beak pipe 10 and water is drained from the outlet pipe 11. The hot compressed gas, which is pressure-fed from the discharge pipe 2 of the Roots blower 1 to the gas flow pipe 4, is connected to a spirally wound flexible hose. It passes through a passage 16 between the supports 7 on the outer periphery of the tube 8, and on the same inner side between the array of sub-supporters 12 and through a passage 17 in the center of the gas flow tube 4, and between it and the water-cooled spiral flexible hose 8. Since the pleated flexible hose 8 is spirally shaped, the stirring and mixing effect of the compressed gas on the inner surface of the gas flow tube 4 is remarkable.

用に有利に適応できる効果をもつ。 The present invention has the configuration as exemplified above, and a flexible hose 8 made of a thin corrosion-resistant metal that has almost no shape retention like the conventional spirally formed steel pipe is attached along the inner surface of the gas flow tube 4 which is spirally wound. The gas flow tube 4 is inscribed in the supports 7 arranged in a ring shape at intervals, and is further supported and kept in shape by the sub-supporters 12 arranged in a ring shape at intervals at the center of the gas flow tube 4. Even when the compressed gas discharged from the discharge port is passed through the passages 16 and 17, the helical shape of the flexible hose 8 does not collapse, and since the contact area of the flexible hose 8 is large, the heat exchange rate can be increased. Since the wound flexible hose 8 is made of a corrosion-resistant thin metal plate, the efficiency of heat radiation can be sufficiently increased. Furthermore, since the flexible hose 8 can be freely bent into a spiral shape, there is no need to form it into a spiral shape in advance, making it easier to assemble and manufacture the radiator of the present invention, and also to manufacture products at lower costs. It has the effect of being advantageously applicable to the use of a low pressure blower of about 3Kg/cm 2 to 1Kg/cm 2 .
