Device for radiating uv and/or ir radiation to a human body in a humid room

Device for radiating UV and/or IR radiation to a human body, comprising:

• an upright housing comprising a circumferential wall and a rear wall connected to said circumferential wall, wherein said upright housing defines an accommodating space;
• at least one radiation unit accommodated within said accommodating space, wherein each radiation unit comprises at least one radiation source for radiating UV and/or IR radiation, and at least one reflector;
• and
• an inner radiation transmitting wall, covering the at least one radiation unit, and an outer radiation transmitting wall, covering said inner radiation transmitting wall, and, directly or indirectly, connected to the housing to close the accommodating space at least partially, wherein the inner radiation transmitting wall and outer radiation transmitting wall are spaced apart;
• and
• a cooling circuit for cooling the one or more radiation units and/or the inner radiation transmitting wall and/or outer radiation transmitting wall, which cooling circuit comprises:
• at least one cooling channel inlet at the bottom part of the housing,
• at least one cooling channel outlet at the bottom part of the housing,
• a cooling channel connecting to both the at least one channel inlet and the at least one channel outlet;
• and
• at least one fan arranged to force cooling air sucked by said fan into the at least one cooling channel inlet to flow through the cooling channel and to be removed via at least one cooling channel outlet meanwhile cooling the at least one radiation unit and/or the inner radiation transmitting wall and/or outer radiation transmitting wall, wherein the at least one cooling channel inlet and the at least one cooling channel outlet are aligned in width direction of the housing.
