Abstract

The invention provides an irradiation device (1) designed to be mounted to an irradiation reactor (20), comprising: an irradiation source (2), preferably an UV-LED, mounted on a heat conductive substrate (3); a disk-like heat sink (4) configured to removably receive the conductive substrate (3) such that heat transfer from the substrate (3) to the heat sink (4) is possible at a contact surface (4a) and such that the irradiation from the irradiation source (2) can pass through an opening (5) of the heat sink (4) into aninterior volume (21) of the irradiation reactor (20) when the irradiation device (1) is mounted to the irradiation reactor (20), wherein the opening (5) of the heat sink (4) is closed by a quartz window (6); fixation means (7) releasably biasing the substrate (3) against the contact surface (4a) of the heat sink (4); and a fluid channel (8) extending along and/or through the heat sink (4), wherein the fluid channel (8) is arranged to communicate with a fluid inlet or outlet port (22) of the irradiation reactor (20) and with one or more outlet openings (9) for discharging the fluid into the interior volume (21) of the irradiation reactor (20) or with one ore more inlet openings (9) for feeding the fluid from the interior volume (21) of the irradiation reactor (20) into the fluid channel (8).
