<p>PURPOSE: A single flow path heat absorbing/releasing device for forward and backward pumping is provided to pump fluid to the forward direction or the backward direction according to cycle, thereby preventing a foreign material accumulating. CONSTITUTION: A single flow path heat absorbing/releasing device comprises: a bidirectional fluid pumping unit(123) which pumps fluid by creating positive pressure or negative pressure; a flow direction change period controller(250) which controls the temperature distribution state of fluid(10) which passes through a flow passage(101) and a heat exchange material or controls the temperature of the heat exchange material by controlling the flow rate of the pumped fluid by the bidirectional fluid; and a power supply(300) which includes the city electricity system of DC or AC or a device which independently supplies electrical energy.</p> |
