Abstract
A cooling unit comprising a coolant fluid pathway in which there is (a) a centrifugal pump which serves to pump coolant fluid along the pathway when the unit is in use, and (b) a heat exchanger which serves to cool the coolant fluid which is thus pumped along the pathway. The pump has a rotor constituted by a magnetically contactlessly driven impeller which is provided with at last one magnet and which is enclosed within a housing, and stator outside the housing and provided with at least one electromagnet operable to act on the said at least one magnet to rotate the impeller.
