COOLING
The power supply should have thermal connection with low thermal resistance between aluminium plate of the
power supply unit and liquid cooling cold plate. The temperature difference of contact area of cold plate and power
supply should be <5
°
C at worst case (total power dissipation of each PSU max. 300W). Recommended is to use
heat transfer paste with thermal conductivity 2.5 W/m.K between unit and cold plate (surface roughness Ra = 3.2
of the aluminium plate is acceptable).
Recommended tightening torque of M4 screws for assembling unit to aluminium cold plate is 3.5 - 4 Nm.
1)
Note 1)
: Recommendation is for thread cut in aluminium plate, thread length 10mm. Tightening torque depends on the material
hardness of the used aluminium cold plate and used screws.
