Abstract:
1. A fluid heat transfer device comprising: a heat exchanger having a first side, wherein the heat exchanger has an inlet manifold having a first and second outlet on opposite ends of the first side and an outlet manifold having a first and second inlet on opposite ends of the first side of the heat exchanger; at least one first fluid piping coupled to the first outlet of the inlet manifold and to the first inlet of the outlet manifold to form at least one first circuit within the heat exchanger; at least one second fluid piping coupled to the second outlet of the inlet manifold and to the second inlet of the outlet manifold to form at least one second circuit within the heat exchanger; at least one bidirectional fluid pumping device coupled to one of the inlet manifold and the outlet manifold to pump a thermal conductive fluid in forward and reverse directions; and at least one periodic fluid direction-change operative control device that controls the at least one bidirectional fluid pumping device to periodically control a flow direction of the thermal conductive fluid that is originally pumped in a first flow direction to alternately flow in a second direction, wherein the at least one first and second circuits are configured in a way such that the thermal conductive fluid is flowable in the heat exchanger such that a flow through the at least one first circuit is in one flow direction and a flow in the at least one second direction is in a parallel and opposite flow direction to the one flow direction.
