An electrically powered cooling unit (130), such as a fan unit, is mountable
on a support structure (110) within a housing (140), for example
a computer housing. The support structure (110) can mount one or more electrically
powered cooling units (130). Each cooling unit (130) includes an
electrical connector (400) fixed relative to the cooling unit and cooperable
with a connector of the support structure, so that offering the cooling unit up
to its mounting position completes the electrical connections between the cooling
unit and the support structure. In alternative embodiments, a single structure
is used both to physically support and electrically connect the cooling unit (130)
to the support structure (110).
