2. The principle of the cooling
The inner deionized water in the water tank is pumped by the magnetic pump to cool the YAG
rod, pulse lamp, two electrodes. The heated deionized water goes through the heat exchanger
and returns to the water tank. The resistivity of the deionized water must be higher than 0.5 M
-
cm. When the deionized water becomes dirty or the resistivity of it becomes higher, the Xenon
lamp may can not be ignited and the laser cavity and the glass tube may be stained. In this
situation, the deionized water has to be changed immediately. ( the deionized water should be
changed one time every week when the laser system is operated continuously)
In the heat exchanger, the Freon is used to take the heat away from the inner deionized
water. In order to ensure the proper working of the system, there is an over temperature
contactor and over flow controller in the cooling system to supervise the water in the laser.
Once there is no enough water flow or the water pump does not work properly, or there is no
enough water in the water tank, the laser power supply will be turned off immediately to prevent
from the lamp exploding or the rod exploding.
