Liquid cooling option (Liquid cooling LC)
As an option Regatron power supplies can be equipped with integrated
liquid cooling of the power section.
The advantages of liquid cooling:
Noise reduction
The majority of the power loss is removed via the
liquid cooling. The load on the built-in ventilation is reduced. In
addition, the device fans have a programmable fan controller that
significantly reduces the speed of the fans.
The noise emissions are reduced.
Greater temperature tolerance
The device can be used in areas with a higher ambient tempera-
ture if the cooling liquid is correspondingly pre-cooled or is con-
nected to a larger cooling water system.
A power loss primarily occurs in the following device elements:
Power semiconductor elements
with 90
– 95 % of the total power loss.
These elements are fastened to a heat exchanger. The heat is
removed from the interior of device using a cooling medium.
Inductive and resistive elements
with 5
– 10 % of the total power loss.
The heat is dissipated to the environment via a slowly rotating
fan built into the rear wall.
Waste heat comparison
By using a water cooling circuit the heat is removed as follows:
Via the water cooling circuit
Approx. 85 % of the total power loss is removed.
Via the ambient air
Approx. 15 % of the total power loss is dissipated to the ambient
air by components that are not connected to the water-cooled
heatsink.
