What is the function of the Xenon lamp aging test chamber's Xenon arc lamp cooling unit?

All types of Xenon lamp aging test chamber xenon arc lamp exposure units are equipped with suitable triggers, reactance transformers and indicating and control equipment to control the lamp power manually or automatically. For manually controlled units, the lamp power should be adjusted periodically to maintain the specified spectral irradiance

In order to cool the Xenon lamp aging test chamber of the xenon arc lamp, with distilled or deionized water at least 378.5L / h flow through the lamp components. To prevent contamination and reduce deposit formation, the water can be purified with a mixed-bed deionizer close to the front of the lamp. The recirculating cooling water of the arc lamp is cooled and prevented from contamination by a heat exchanger, which can be used as a heat exchange medium with tap water or refrigerant.

Standard use of Xenon lamp aging test chamber device is equipped with a countdown timer to control the exposure time. Some devices are also equipped with a burst light monitor, so that the preset radiation exposure is reached as soon as the device is shut down. Temperature and humidity control: Since some plastics are temperature sensitive, accurate and tight control of temperature is essential in tests conducted in accordance with standards. Temperature is measured and controlled using a standard thermometer or blackboard thermometer. The thermometer is mounted on a rotating specimen holder with the surface in the same corresponding position as the specimen and subjected to the same test effects.

The exposure device is placed in a thermal barrier to reduce the effect of any room temperature changes. The ventilation system provides a steady flow of air through the chamber, and the temperature of the air is automatically controlled by recirculating the warm air in the chamber and mixing it with the cold air outside the chamber.

In order to achieve the Xenon lamp aging test chamber specified standard temperature or black plate temperature and maintain the specified constant temperature of a thousand spheres, the fan speed can be adjusted and controlled when necessary. The specimen holder is mounted on a vertical or inclined cylindrical frame or rotating frame, and the lamp is located on the horizontal and vertical axis of the exposed area of the specimen holder.
