Coolcell

The Cannon Datacom 'CoolCell' is a patented air-to-air heat exchanger which provides a quiet, reliable method of equipment cooling for low to medium heat dissipation requirements. The 'CoolCell' would usually cover heat dissipation of between 200-watts to 800-watts per chamber. The system avoids the complexity, cost and maintenance implications of refrigeration.

Features

• The 'CoolCell' is a highly compact unit, which uses the effect of both laminar and turbulent flow to achieve high levels of thermal transfer (heat removal).
• A major feature of the 'CoolCell' is the ability it provides to isolate external air and its attendant contamination from the air sealed internally in the equipment or thermal chamber. 
• This facility minimises the likelihood of equipment failure due to dust or other contaminants and in most instances avoids the need for air filters and their subsequent maintenance cost.
• The 'CoolCell' occupies relatively little space for its heat removal capacity, hence it can usually be accommodated within the main body of the enclosure, most conveniently in the roof void.
• This is a major advantage over alternative systems, which often require an additional bolt on enclosure to house the cooling unit, creating an unsightly system with increased visual impact and noise.
• The 'CoolCell' uses ambient air from the atmosphere to carry away heat from the system. The ambient temperature range of the cabinet's installation site influences the upper and lower temperature limits of the air in the equipment or thermal chamber.
• In its simplest form the 'CoolCell' will generally maintain an equipment chamber at between 5°C to 15°C above the prevailing ambient air temperature. The 'CoolCell' will typically give a ∆ t/Watt of 0.03°C.
  
  As an example, if the ambient air temperature is 28°C and the equipment is dissipating 450-watts of wild heat, then the temperature rise within the equipment or thermal chamber would be: (450 Watts x 0.03ºC)+28°C= 41.5°C, (i.e. a rise of 13.5°C above the ambient).

Hot Conditions

For installations in hot climatic conditions, where high ambient temperatures pose a more severe heat load, the  'CoolCell' may be upgraded by the addition of chilling units.

These units may be Cannon 'ChillCell' solid state devices, or 'FreezeCell' refrigeration units, depending on the thermal challenge.

Note: 'CoolCell' heat exchangers are configured specifically for each project in order to achieve optimum performance.
