What is the difference between air cooling and water cooling in Xenon lamp aging test chamber?

Xenon lamp aging test chamber mainly provides a destructive light wave environment for scientific research, so as to accelerate aging and detect product quality in advance. There are two types of air-cooled Xenon lamp aging test chamber and water-cooled xenon lamp aging test chamber commonly used in the market. What are the differences between these two types of xenon lamp aging test chambers?

1. The air-cooled Xenon lamp aging test chamber uses natural air to cool the lamp. The xenon lamp is located above the device. There is a flat sample rack with adjustable height in the sample chamber. When the xenon lamp is used for a certain period of time, the sample can be shortened. The distance between the rack and the xenon lamp can reach the specified irradiance, so the test chamber is also called the flat Xenon lamp aging test chamber. This lamp has lower energy consumption, longer service life, and is cheaper than water-cooled lamps It is expensive. The radiance of this kind of test box may be lower than that of the water-cooled xenon lamp aging box during the test, but the service life of the air-cooled lamp is much higher than that of the water-cooled lamp, and the requirements for the environment are not so high. The service life of this kind of xenon lamp is basically more than 1600H; the durability.

2. The water-cooled xenon lamp aging box is cooled by cooling water to the lamp tube. There is a drum sample holder inside, which rotates around the xenon lamp tube, so it is also called a drum-type xenon lamp. There is a water-cooled xenon lamp tube in the middle of the drum. This kind of lamp has the characteristics of high energy efficiency, strong irradiance, and uniform irradiance received by the sample during the test. Conductivity, cleanliness, temperature, etc. have particularly high specifications, otherwise the surface of the lamp tube will turn black and the lamp tube will be scrapped. The average service life of this xenon lamp is about 800H.
