To provide a heat exchange apparatus by making fluid pass through a pumping device which carries out pumping in two directions.

The pumping device 123 for pumping fluid controlled by a direction changing controller 250 periodically changing a flow direction into two directions is serially connected to primary-side fluid piping 101, a one-way fluid pump 120 is serially connected to secondary-side fluid piping 102, a primary-side fluid 10 indicating a flow direction with different forward and backward directions passing through the primary-side fluid piping 101 is periodically forcibly fed through the pumping device 123 pumping the fluid in two directions, and by a force feeding a secondary-side fluid 20 passing through the secondary-side fluid piping 102 by the one-way fluid pump 120 when a heat pump or the heat exchange apparatus is operated, a distribution state of a temperature difference in relative positions of the primary-side fluid piping 101 and the secondary-side fluid piping 102 indicating a positional relationship of a fixed structure is changed.
