Water cooling requirements for output optical cables:
a) Water flow requirements: HQBH output cable water flow is between 1.5L/min and 2.0L/min;
QD output cable water flow is between 2.5L/min and 3.0L/min; QP output cable water flow is
between 3.0L/min and 4.0L/min;
b) Water cooling pressure: 0.4Mpa~0.6Mpa at the water inlet;
c) Water inlet and outlet connector type: M5 to ϕ6 quick-tightening connector(HQBH); M6 to ϕ8
quick-tightening connector(QD, QP);
d) Water pipe type: outer diameter ϕ6 and inner diameter ϕ4(HQBH); outer diameter ϕ8 and inner
diameter ϕ5.5(QD, QP);
e) Cooling water direction: unidirectional. The water pipe shall be connected in strict accordance
with the water inlet and outlet direction marked on the shell.
f) Cooling water quality: deionized water, distilled water, purified water; it is recommend to
replace once a month, and the replacement period should not exceed two months.
g) PH value of cooling water: 5.5~9;
