Cold water machine applied in the vacuum coating machine cooling
Cold water machine in the vacuum coating machine cooling application, its advantage is to maintain the temperature of the vacuum coating machine, make it work to achieve the purpose of temperature control and high precision, high efficiency.
In the case of no cold water machine before, natural water tower and water cooling are inevitably influenced by natural temperature, and the way of control is too volatile.
Therefore, it can be said that the cold water machine is very important auxiliary cooling equipment in the vacuum coating equipment, because of the cold water machine is directly related to the effect of vacuum coating machine work is good or bad.
why vacuum coating machine to form a complete set of cold water machine?
This is the view of the principle of vacuum coating: coating materials evaporation at high temperatures in the workpiece surface crystallization.
Due to the evaporation air to the membrane material molecular crystals will produce resistance caused by collision made rough, so must be under high vacuum to make crystal light, fine, if vacuum degree is not high the crystals will lose luster, adhesion strength is also very poor.
the advantages of vacuum coating machine cold water machine!
Cold water machine is equipped with refrigeration system and cooling water circulation system, the water temperature in 5 ℃ ~ 30 ℃ range adjusting control, can achieve the goal of controlling temperature and high precision, high efficiency.
Its cooling principle is: the refrigeration system will be water cooling, again by cryogenic cooling water pump into the vacuum coating machine for cooling, cold water machine chilled water will heat temperature after it was taken back into the water again, achieve the effect of cooling.
