Selection of water cooling and air cooling for xenon lamp aging test chamber
The xenon lamp aging test box is divided into water cooling and air cooling, which is mainly reflected in the cooling method of the lamp. When purchasing, you need to understand the difference between the two and make a reasonable choice based on the actual situation!
The xenon lamp aging test box is the most common type of light aging test equipment. The xenon arc lamp that can simulate the full sunlight spectrum is used to reproduce the destructive light waves existing in different environments, which can provide a corresponding environment for scientific research, product development and quality control. Simulation and accelerated testing. The xenon lamp weather resistance test chamber measures the light resistance of the material by exposing the material to ultraviolet (UV), visible light and infrared light. It uses a filtered xenon arc lamp to produce a full sunlight spectrum that is consistent with sunlight. A xenon arc lamp with reasonable filtering treatment is the best way to test the product's sensitivity to long-wavelength ultraviolet and visible light in direct light or sunlight through glass.
In terms of light source, there are two types of xenon arc lamps used by Wuhan Shangce Test Equipment Co., Ltd. As the heat of xenon arc lamps is very large, air cooling and water cooling are used. The power of air cooling is generally 1.8KW. The water-cooled one is 6KW. Xenon lamp aging test box water-cooled lamp is generally placed in the inner box vertically, the sample holder rotates around 360°, the rotation rate is adjustable from 1r to 5r/min, the sample is hung on the rotating rack, so that the sample is evenly exposed to light. The xenon lamp aging test box has three air-cooled tubes installed side by side on the top of the inner box, level with the lower sample holder, and the optical fiber illuminates the sample surface vertically, and the sample is placed arbitrarily. Here, it should be emphasized that if the sample is large and it is not easy to hang, it is recommended to buy a flat air-cooled xenon lamp aging test box.
Although the xenon lamp aging test box is divided into water cooling and air cooling, in terms of irradiance control, our equipment is equipped with a light sensor probe, a high light control system, which can be The light energy drop caused by other changes shall be compensated in time. The solar eye allows the appropriate light irradiance to be selected during the test, and can even select the light irradiance equivalent to the noon sunlight in summer. The solar eye can continuously monitor the light irradiance in the irradiation room, and can maintain the irradiance at the working setting value by adjusting the power of the lamp tube. Due to long-term work, when the irradiance drops below the set value, a new tube needs to be replaced to ensure the irradiance is normal.
In summary, when purchasing water-cooled and air-cooled xenon lamp aging test chambers, we must first understand the characteristics of the product itself, and then choose according to the test standards.
