Abstract
A thermal transfer device comprising a thermal transfer surface and a passageway for conducting a thermal transfer fluid from an inlet to an outlet while passing in thermal contact with the thermal transfer surface. The passageway has at least two spiral passages and a connection channel connecting the at least two spiral passages to permit flow of the heat transfer fluid from a first spiral passage to a second spiral passage; thereby forming a path for the flow of the thermal fluid from the inlet, through the passageway, along the first spiral passage to the connection channel, then along the connection channel to the second spiral passage, and then to the outlet.
