C&C Power’s backup battery cabinets are designed with optimal convection cooling and an optional CoolCab battery cabinet cooling fan. Typical VRLA batteries want to be no warmer than 77°F. Optimizing battery temperatures maximizes battery life. The challenge was to reduce the internal battery cabinet temperature taking into consideration the cabinet internal battery layout and the environment of the battery cabinet.
Battery Convection Cooling
Our engineering team at C&C Power has invested many months in developing and testing thermal temperatures of batteries while enclosed in battery cabinets. Small strategic changes in airflow have a big effect on a cabinet’s ability to transport heat up and out the rear of the cabinet. By running thermal tests on battery temperatures and airflow at an ambient temperature environment of 75°F, our engineers were able to design options to optimize convection cooling.
Their conclusions through Computational Fluid Dynamics have led them to develop our patented, tiered battery cabinets featuring industry-leading temperature attributes. This innovative convection cooling solution achieves temperature deltas as low as 1.9°F on float charge.
Battery Cabinet Cooling Fan
The standardized battery cooling solution also has an optional CoolCab battery cabinet cooling fan for tackling rooms with characteristics that inhibit natural convection cooling. Overly pressurized rooms or layouts that block rear venting may need this additional precaution.
Simulation tests on each cabinet have led us to pinpoint the ideal location for each CoolCab fan system. The result is that a battery cabinet with the fan option yields a remarkable less than .5°F battery to battery delta temperature and a 1.5°F battery to ambient while on float. The combination of the cabinet convection cooling solution and fan option will result in more optimal battery temperatures.
UBC75 Battery Cabinet
The UBC75 Battery Cabinet, pictured above in the thermal testing, is our most forward-thinking design to date. It is designed to be the most power-dense option on the market. All battery cabinet units shipping today have this optimal convection cooling solution. The optional fan can either be factory installed or retrofitted to existing cabinets. It is designed for easy snap-in installation on site.
Both solutions feature our front-access design using a variety of front terminal battery models, and both can be seismic certified whenever required. Contact our support and service technicians for questions on installation.
