At the beginning of September, we were fortunate enough to enjoy a second summer as temperatures soared and the sun beat down. Many took advantage of the opportunity to socialise outdoors, walk in the countryside, and perhaps enjoy a cheeky pint. For roadside cabinets, however, the higher temperatures are harsh and can cause temperature sensitive equipment to trip or malfunction.
At Ritherdon, we pride ourselves on identifying new development opportunities through carrying out trials and gathering data. We have created a number of testing cabinets that we use to trial different configurations of ventilation in an attempt to find the best way to ensure our cabinets stay cool during the summer.
On this occasion, we performed a series of experiments using two RB Cabinets and chose the RB1250 size with double doors. In each cabinet we placed six thermocouples on the backboard that we used to measure the temperature at various positions. We also measured the ambient temperature outside the cabinet for comparison.
Both roadside cabinets were ventilated using our standard method – an exhaust fan at either side of the top of the cabinet and a bank of louvres for inlet flow at the bottom of either side. RB Cabinets come with vents as standard.
Analysing the data gathered from these test cabinets revealed two interesting points to consider:
