Abstract
PURPOSE:To exclude effectively the heat generated by an infrared ray transmitting fiber, by putting a liquid refrigerant of a specific amount into an inner space formed at the outside of the infrared ray transmitting fiber provided to the inside of a flexible tube. CONSTITUTION:Both ends of a flexible tube 1 (made of a metal) are sealed airtight bya sealing member 2 made of the Ge, Si, etc. having high transmittance of the infrared rays. An infrared ray trnsmitting fiber 3 is provided into an inner space. A film having the solvent resistance is coated at both ends of the fiber 3 with a contact to the matter 2. Then the vacuum deaeration is carried out through a lead-in part 4 of a metallic tube 1, and a refrigerant 5 (''Flon '', etc.) is enclosed by 2-5% capacity of the inner space. The refrigerant 5 absorbs the heat generated by the fiber 3 and vaporizes it. Then the evaporating temperature of the refrigerant 5 is set higher than the using temperature of the fiber 3 to repeat the vaporization and the liquefaction within the inner space. Thus the continuous cooling is carried out. It is also effective to set a porous matter 6 at the outside of the fiber 3 and to hold the refrigerant.
