There is no difference in usage or function, but the structure is the sameThere are differences in the effects under experimental conditions. Please refer to the following six items for specific differences:1、 Structural difference: The air-cooled xenon lamp is a flat plate type, with the lamp tube placed flat on top of the equipment and a flat sample compartment below, which cannot be removed for some irregularitiesThe sample product is easy to place, but the testing area is small. The water-cooled one is a rotating drum xenon lamp (also known as a rotating cage xenon lamp). The lamp tube is rigidly installed with a rotating rim around itCage can360 Rotate the product for testing, with a larger irradiation area available. However, it is recommended that the test samples be either resampled or sliceduse2、 The difference in lamp power, commonly used power for air-cooled xenon lamps is1500w/Support or2500W/It is not recommended to use air cooling for higher power output. It is recommended to use water cooling instead,Because it is easy to fail. Water cooled lamp tubes have4500W/Support or6000W/The support and volume affect the number of light tubes, and water-cooled and air-cooled products have the same amount of water-cooled lampspipe1 Just support it, the possibility of air cooling is the least6 Support even7~8Support. (Explain why there are different power lamps and under what circumstances high-power lamps are used)Tube, it means under the same wavelength, for example420nmFrequently done1.1W/m2and1.2W/m2But the customer requires it to be done1.5W/m2If that's the case, it's an enhanced versionThat's it.3、 Uniformity difference: Water cooling has better uniformity. The uniformity of a single lamp tube is good, but the uniformity of multiple lamps is not as good because there is no interval between the lampsDifferences, etc.4、 The difference in equipment prices is that water-cooled xenon lamps are about twice as expensive as air-cooled xenon lamps. Because air cooling and blowing in can cool the lamp tube, while water cooling is sufficientWater needs to be used to cool the lamp tube, which requires high process requirements. Water also needs to be treated for water quality. Air has strong penetration, and different types of water may contain impuritiesImpurities can also bring dirt, and after using it for a period of time, the surface of the lamp tube will be covered with dirt and turn white, making it difficult for light to pass through. Therefore, when dealing with these issuesThere will be an increase in costs and more complex technology.5、 The cost of consumables after air cooling will be higher than that of water cooling. For example, for the same area of test material, air-cooled lamps may require multiple units, but water-cooled onesfluorescent tube1 Just one tube is enough, although a water-cooled lamp tube will be more expensive than an air-cooled one2 Approximately twice the size, but under the same testing conditions, air cooling may be necessary6 Supporting lamp tubeeven7~8Only one tube is needed to achieve it, but one tube is sufficient for water cooling, so the cost of replacing the lamp tube in the later stage will be expensive.6、 Selection difference: When choosing between air cooling or water cooling, all wavelength requirements can be purchased with air cooling or water cooling, only for testing purposesIt is recommended to choose the sample in this way. If you want to put a lot of things or a large area, it is recommended to use water cooling, because the area of water cooling is three times that of air cooling, but this requirement is for sheet-like materialsOr for coatings, air cooling is recommended for small areas, and air cooling is recommended for irregular products.
