15
➢ It is recommended to use purified water.
➢ In order to prevent mould growing that may lead to pipe blockage, we recommend to add
alcohol about 10% of the total volume.
➢ If the product is used in an environment that ambient temperature is between -10℃ and
0℃, we recommend to use 30% alcohol, and replace it every two months.
➢ If the product is used in an environment that ambient temperature is below -10℃, please
to use dual-system chillers (with heating function) and ensure uninterrupted operation of
the cooling system.
(2) Requirements for output cable cooling system:
➢ Rate of liquid flow: 1.7-2.0 L/min;
➢ Pressure of liquid flow: < 0.6 MPa at the inflow;
➢ Type of liquid exchange junction: SMC MS-5H-6:
➢ Type of tube: outer diameter 6; inner diameter 4;
➢ Direction of cooling liquid: unidirectional; connect the tube with the water-pipe strictly
according to direction shown on the layer of the tube;
➢ Type of liquid: de-ionized water, condensed water, pure water;
➢ PH value of liquid: 5.5-9;
➢ Filter is needed for the cooling system, and the size of the solid residual practical should
be within 100um;
➢ Maximum temperature of liquid: 45℃:
➢ Minimum temperature of liquid: greater than the saturated dew-point 5℃;
➢ Additive to the liquid: satisfies the requirements of PH value and size of solid residual
practical as above;
➢ Radius of the bending of the armored pipe: off-work state (i.e. transportation and
reservation): minimum radius of bending ≥ 20 cm; in-work state: minimum radius of
bending ≥ 30 cm;
