Increase.Therefore the distance between the adjacent constant-current stabilizer for needing to be arranged is shorter and shorter.
In addition, exporting to condensation this section of collector, because the space of this section becomes larger suddenly, the variation in space from tedge
It will lead to quickly flowing upwards out and assemble for gas, therefore spatial variations will lead to the vapour phase (vapour group) of aggregation from tedge position
Into condensation collector, due to gas (vapour) liquid density contrast, air mass leaves adapter tube position and will move rapidly upward, and air mass original space bit
It sets and the liquid of wall surface is pushed away by air mass while will also spring back and hit wall surface rapidly, form impingement phenomenon.Gas (vapour) liquid phase is more not
Continuously, air mass aggregation is bigger, and water hammer energy is bigger.Impingement phenomenon will cause biggish noise vibration and mechanical shock, to equipment
It damages.Therefore in order to avoid the generation of this phenomenon, the distance between adjacent constant-current stabilizer being arranged at this time is shorter and shorter,
