Abstract:
1. A system for exchanging heat between two flows of fluids in a double flow circuit heat exchange device comprising: a heat exchange device having a first flow circuit and a second flow circuit being configured to exchange heat between two flows of fluid, said first flow circuit having an inlet and an outlet and said second flow circuit having an inlet and an outlet; at least two bidirectional fluid pumps, wherein a first of said two bidirectional fluid pumps is coupled to one of the inlet or outlet of the first flow circuit; and wherein a second of said at least two bidirectional fluid pumps is coupled to one of the inlet or outlet of the second flow circuit; a power source configured to provide power to the at least one bidirectional fluid pump; a periodic fluid direction-change operative control device configured to control operations of the at least two bidirectional fluids pumps; wherein the at least two bidirectional fluid pumps are separately arranged on the first and second flow circuit so that the periodic fluid direction-change operative control device is operable to periodically change a fluid flow direction of a fluid in the respective first flow circuit or the second flow circuit.
