Camera Heating and Cooling

KARLSRUHE, Germany, Feb. 2, 2011 — A multistage climate control concept from autoVimation makes camera systems suitable for use in adverse environments. Heating and cooling modules that can be easily mounted to the outside of the company's protective enclosures, extend the operating range of cameras and improve the reliability of image processing systems.
Climate control begins with passive cooling. Proprietary and patented heat guide/quick lock brackets ensure optimal heat dissipation from the camera to the enclosure. The latter thereby acts as a heat sink, giving off heat to the ambient air via its surface and enabling cameras to be used at ambient temperatures up to 10 °C above the limit listed by the manufacturer.
For camera systems that are used at ambient temperatures of >50 °C, or in environments with a lot of radiant heat, the company also offers water-cooling modules that are connected to an external water-cooling system via a closed water circuit. They attach to the outside of the camera enclosure, efficiently dissipating the heat. Various cooling systems that optionally include temperature and flow monitoring with an emergency shutdown are available for different ambient temperatures.
Depending upon the model, these cooling systems perform between 775 and 3000 W. Several cooling modules can be connected to the industrial cooling units, allowing users to cool three or more cameras simultaneously. Upon request, the company will develop customer-specific cooling systems, e.g., ones that include a heating cartridge. The cooling systems can be easily retrofitted to all protective enclosures with a dovetail profile.
A controlled heating element prevents overheating. An IP65 control module installed at a distance of 500 mm monitors the enclosure's temperature via a PT100 thermal sensor, heating it to a maximum temperature of 20 °C. Through the heating element's large surface, the enclosure and camera are warmed evenly, preventing dew points within the enclosure. Because the heating element has direct contact with the enclosure cover, the front panel is heated as well, which prevents condensation. The 35-W heating unit measures 12 mm high.
