Heat-pipe Enclosure Cooling
 
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.
