Passively cooled enclosures slash costs

08 October 2008

Intertec has launched a passively cooled enclosure that exploits a phase-change material (PCM) to maintain the temperature of electronics equipment at 10 degrees lower than peak ambient temperatures. Requiring no power supply to operate, Intertec has produced a standard cooling enclosure with enough internal space to meet common application requirements.

PCMs can provide a cooling mechanism by absorbing and storing the large quantity of energy needed to change the material's state from solid to liquid as the melting point is passed — during the normal daytime temperature rise. This energy is then released as the PCM re-solidifies during cooler periods. Intertec has chosen a PCM with a phase change temperature of 34 degrees C.

The PCM passive cooling system, provides approximately 25 litres of usable space for mounting electronics equipment, and will dissipate up to 10 W of heat. There is no need to add fans or vents, so the IP rating against dust and water remains unchanged.

The enclosure itself is fabricated using a long fibre reinforced glass-reinforced polyester sheeting, which provides great structural strength, combined with high resistance to weather and the corrosive effects of aggressive chemicals.

The enclosure can deliver major reductions in system building costs.
