The color selector is equipment for automatically sorting out heterochromatic particles in particle materials by utilizing a photoelectric detection technology according to the difference of optical characteristics of the materials. At present, the color sorter is widely applied to the fields of food sorting, garbage sorting, ore sorting and the like.

When the linear array camera works, a measured object needs to be continuously photographed and the photographed picture needs to be transmitted to the image processing system, and in the process, the WGB-LED high-distance linear light source continuously outputs high-intensity visible light, so that the whole system generates high heat, and the heat dissipation needs to be carried out in time to ensure the normal operation of the color sorter.

The current common heat dissipation methods include air-cooling heat dissipation and water-cooling heat dissipation. The air cooling heat dissipation utilizes a fan or an air conditioning refrigerant and the like, and the heat is taken away to achieve the heat dissipation effect by enhancing air convection or blowing low-temperature air to the part to be dissipated.

Therefore, the applicability of air cooling heat dissipation to the color selector is low. Therefore, the cooling device of the existing color selector generally adopts a water cooling heat dissipation mode.
