Abstract
A UV tube for killing microorganisms in a fluid generally includes a hollow tubular body, a UV isolation layer, and at least one UV light source. The hollow tubular body has an inlet port, an outlet port, and a fluid channel portion between the inlet port and the outlet port. The fluid channel portion has an inner surface. The UV isolation layer is disposed at the inner surface of the hollow tubular body for sheltering the inner surface of the hollow tubular body. The fluid is allowed to flow through the UV isolation layer. The UV light source is provided at the hollow tubular body and/or the UV isolation layer. The UV isolation layer can absorb and/or reflect the ultraviolet light emitting from the UV light source, so that the possibility of the fluid channel portion being irradiated by the UV light can be reduced.
