Photocatalysis shielding heat radiating device

The invention relates to a photo-catalytic shielding heat dissipating device, comprising a light shielding box body which can contain a photo-catalytic system and is provided with a heat dissipating system. As an important composition part of the photo catalysis, the photo-catalytic shielding heat dissipating device avoids the radiological impact to operators caused by the light of photo-catalytic reaction, the influence on catalytic reaction in the system caused by light outside the system and prevents the overheating of the system and the light source. The device which is simple in structure is suitable for the fields of scientific research and production and teaching such as photo-catalytic synthesis, degradation, transformation and reduction. By selecting special materials, the shielding heat dissipating device has the effect of preventing ultraviolet radiation, avoiding the influence of light sources and temperature differences of external environments.
