Abstract:
1. An apparatus for curing a liner of a pipeline, the liner including a resin that is curable by exposure to electromagnetic radiation of a specific wavelength or in a specific wavelength range, the apparatus comprising: a housing configured for installation within a pipeline passage defined by an inner surface of the liner, the housing defining opposite first and second ends, the housing comprising an outer wall and an inner wall defining a cooling fluid passage extending longitudinally through the housing between the first and second ends; a plurality of LED's distributed around the outer wall of the housing and operable to irradiate substantially all of the inner surface of the liner with electromagnetic radiation of the specific wavelength or in the specific wavelength range when the apparatus is installed within the pipeline passage; and a plurality of heat dissipating elements on the inner wall of the housing and extending into the cooling fluid passage; wherein the LED's are connected in thermally-conductive relationship to the heat dissipating elements, whereby heat is dissipated from the heat dissipating elements so as to cool the LED's when a stream of cooling fluid passes through the cooling fluid passage.
