The difference between the water-cooled lamp and the air-cooled lamp of the Xenon lamp weatherproof test box
In addition to light, xenon arc lamps generate a lot of heat in visible light and IR rays, which poses problems for operation and maintenance. The air-cooled xenon lamp weatherproof test chamber avoids excessive heat generation due to the discharge of a large amount of air through the lamp clamp. This simple and economical device is called air cooling.
Since water is an excellent heat transfer carrier, the water cooled xenon weather test chamber can be operated at a very high wattage to produce high irradiance. However, water cooling systems also have the following disadvantages:
1. The lamp tube and filter device are more complicated, with internal and external filters.
2. Cooling water is similar to high voltage current, so for safety reasons, connectors and seals must be very precise and highly durable.
3. The lamp is very expensive due to the special connectors used.
4. The cooling water must be very pure to alleviate any impurities that build up on the tubes and filters.
5. The cooling water itself must be cooled by a cooler.
6, the pump has the need for maintenance.
