CLAIMS

1. A device (30) for curing a coating substance inside a pipe, the device comprising

a flexible shaft (12) disposed at least partially inside a duct (10), an air inlet channel (14) between the flexible shaft (12) and the duct (10),

a body (32) configured to be attached to the duct (10), a heat sink (48) in connection with the body (32) and defining a plurality of cooling channels (44) which are in fluid connection with the air inlet channel (14), and

a plurality of light emitting devices (42) configured to be cooled by the heat sink (48),

wherein the device further comprises an air outlet channel (34) in fluid connection with the cooling channels (44) of the heat sink (48), and the air outlet channel (34) exits the body (32) from the same side of the body (32) as the air inlet channel (14) enters the body (32).

2. A device (30) according to claim 1, wherein the cooling channels (44) of the heat sink (48) extend in a length direction (L).

3. A device (30) according to claim 1 or 2, wherein the device further comprises a transparent dome (36) housing the light emitting devices (42) inside the dome (36).

4. A device (30) according to claim 3, wherein the dome (36) defines an air space between the inner wall of the dome (36) and the light emitting devices (42) and that the air space is in fluid connection with the cooling channels (44) of the heat sink (48) and the air outlet channel (34).

5. A device (30) according to any one of claims 1 to 4, wherein the air outlet channel (34) is a through-hole in the body (32), parallel to the air inlet channel (14) or the length direction (L) of the device.

6. A device (30) according to any one of claims 1 to 5, wherein the light emitting devices (42) are ultra-violet light emitting devices.

7. A device (30) according to any one of claims 1 to 6, wherein the light emitting devices (42) are UV LEDs.

8. A device (30) according to any one of claims 1 to 7, wherein the device (30) comprises light emitting devices (42) facing at least four different directions which are perpendicular to the length direction (L) of the device.

9. A device (30) according to any one of claims 1 to 8, wherein the device (30) comprises light emitting devices (42) facing to a direction parallel to the length direction (L) of the device.
