Abstract
Example motor cooling radiators for use in downhole environments are disclosed. A disclosed example radiator comprises a cylindrical housing having an annular passageway. The housing defines an inlet at a first end of the housing and an outlet at a second opposite end of the housing. A channel is arranged within the annular passageway of the housing along a spiral path to transport the first liquid and to define a spiral flow passageway between the inlet and the outlet for the second liquid. In operation, the first liquid does not contact the second liquid and heat is transferred between the first and second liquids as the second liquid flows in the spiral passageway.
