Enclosure coolers
Heat-pipe cabinet coolers offer a compact and convenient method of cooling IP 54 enclosures.
An internal fin bank is connected to an external fin bank using
Heat-pipes. A central dividing plate forms an integral sealed part of
the assembly. Installation requires only a suitable rectangular cut-out
and fixing hole locations to be made in the enclosure. The units are
hermetically sealed to the enclosure via the central dividing plate.
Typically, small units handle 200W to 2 kW and maintain an internal
ambient of less than 50°C. Heat-pipe cabinet coolers are produced to
order and are supplied complete with cooling fans to customer
specification.
Heat-pipe heat exchangers
Large scale Heat-pipe heat exchangers are configured individually
to specification. Fin volume together with internal and external mass
flow rates are designed precisely to suit thermal requirements.
Differential volumetric air flow rates are managed by optimal sizing of
ducts. Compact and modular in design, Heat-pipe heat exchangers can
realise up to 70% energy reclaim.
Power Rating from 2 kW to 80 kW
(Max Mean Operational Temperature +250°C).
Rugged enclosure coolers
Heat-pipe Ruggedised Enclosure Coolers provide the latest technical
innovation in development of robust enclosure cooling. These rugged
enclosures are used in situations where sensitive, vitally important
power electronic components are required to operate in some of the most
demanding of environmental conditions. The enclosure shown here is
fully tested to comply to military specification and is used to house
crutial IT systems.
These hermetically sealed enclosures are both gas tight and water
resistant, utililising specially developed internal mounting
technology, the internal operating system is also protected from shock
and vibration.
CRS “flexible Heat-pipes” are attached to the internal electronics
package and provide a high thermally conductive link to dissipiate
internally generated heat to the enclosures external heat sink.
Externally mounted axial fans ensure forced air cooling is available
where installation space maybe seriously confined.
Current applications include in-flight entertainment systems, military
helicopters, fighting vehicles, ships and submersibles.

Externally mounted axial fans
are used to provide forced air cooling. This is generally neccesary
where limited installation space confines the allowable volume of
cooling fins.
