LCP hybrid CW 3311.610 WxHxD (mm) 600x2000x105 10 kW
The unit takes up the heat losses from IT components installed in an IT
rack and thus prevents dissipation of this heat at the place of
installation. The temperature of the room air is maintained at the
server air inlet temperature. The integrated air/water hybrid heat
exchanger with heat pipe guarantees a cooling output of up to 10 kW.
Heat pipes ensure even heat distribution over the exchanger in case of
inhomogeneous component installations in the rack; the IT rack is to be
fitted with the air baffle plates which are available as accessories so
as to form a "funnel" towards the rear and in this way to guarantee 100%
heat transfer via the heat pipe, even distribution of the heat losses
and thus full exploitation of the heat exchanger surface. The unit is
mounted at the rear on 600 mm wide IT racks with fixings on one side.
With its external frame construction, the heat exchanger does not occupy
space in the rack - the full server rack is thus available for the IT
equipment. Thanks to the high-performance heat exchanger and its special
corrugated membrane structure with hydrophilic coating, the exhaust air
flow from the servers is not impaired. The unit can be swung away from
the rack in the same way as a ventilated rear door. The opening angle of
the unit is 130°, also in combinations with several units in a suite.
The IT components installed in the IT rack use their own fans to route
the warm air flow to the air/water hybrid heat exchanger. The heat from
the warm exhaust air flow from the IT components is dissipated by way of
the air/water hybrid heat exchanger. No additional fans are required on
the unit for the cooling of the IT components. The air/water hybrid heat
exchanger results in a minimal pressure loss over the IT components. To
further reduce the pressure loss on the air side, additional air baffle
plates are provided for installation in the roof and floor areas in the
600 mm wide IT rack. The air baffle plates do not hinder the
accessibility for cabling and mounting of the IT components. The cold
water connection of the LCP hybrid is to be found in the side door
frame. The connection point for the feed and return lines (DN 25, 1"
internal thread) is fixed on the unit and is not turned when opening and
closing. Optionally, the cold water supply to the unit can be realised
by way of an external connection hose DN 25 / PN 16, length 1 m (not
included in the scope of supply).
