What is the difference between the air cooling and water cooling of the xenon lamp tube in the ultraviolet weather resistance testing machine

<p> The main factors that cause the material aging of the ultraviolet weather resistance test machine are sunlight and humidity. The xenon lamp climate test chamber can simulate the hazards caused by sunlight, rain and dew. The xenon lamp can be used to simulate the effect of sunlight. The condensation moisture can be used to simulate rain and dew. The tested material is placed in a cycle program of alternating light and moisture at a certain temperature for testing. It can reproduce the hazards that occur outdoors for months or even years in a few days or weeks. Artificial accelerated aging test data can help selection New materials, transformation of existing materials, and evaluation of how changes in formulations affect the durability of products.

The company uses wind cooling to cool the xenon lamp tube for the xenon lamp weather resistance test. A high-power fan is used to cool the three xenon tubes through three special air ducts.

We know that glass is a bad conductor of heat. When the lamp is lit, the temperature of the lamp glass is very high. If the water cooling method is used, it will cause a sudden cold and it is easy to break the lamp. If the air cooling method is used, this problem will be avoided, because the air cooling is to blow the air of the external environment to the lamp tube through the air duct specially made by Dongguan Hongzhan Instrument Co., Ltd. The temperature of the external air is constant, and its The rate of heating and cooling is very slow. During the cooling process, there will be no sudden high or low temperature, so there will be no sudden temperature impact on the glass of the lamp tube and the lamp tube will break.

In addition, air cooling can greatly reduce operating costs. This is the advantage of air cooling compared with water cooling. In addition, water cooling will produce scale in the lamp tube, which will affect the irradiation intensity of the xenon lamp, and therefore will affect the test results of the sample.
