FAN APPARATUS AND ELECTRICAL EQUIPMENT INCLUDING SUCH APPARATUS

摘要

A fan includes a plurality of blades 9 carried by a hub housing 10 mounted on a rotatable motor shaft 6. The shaft 6 includes a heat pipe 11 to transfer heat from the motor bearings 7 and 8 to a heat dissipative plate 15. The fan is particularly useful for cooling electrical and electronic equipment housed within a cabinet, such as, for example, in a telecommunications arrangement.
