Abstract

An enclosure (1), such as a housing for a digital telephone sub-station (2), is cooled by apparatus comprising a first bank (5) of finned tubes within the enclosure (1) and a second bank (12) of finned tubes outside the enclosure (1), at a height above the first bank (5) and connected to the first bank (5) by pipes (18, 19). Refrigerant within the banks (5, 12) and the pipes (18, 19) will be caused, by the effects of air currents passing over the banks (5, 12) of tubes, to move in a circuit formed by the pipes and tubes and to change state to extract heat from the enclosure. A completely passive system can therefore by obtained. <IMAGE>
