PROBLEM TO BE SOLVED: To permit the miniaturization of a device (1) and reduce the restriction of the arrangement of units by reducing the required head difference between a heating heat exchanger (41) or a cooling heat exchanger (42) and tanks (T1, T2) in a heat conveying device. SOLUTION: A mechanical pump (60) is used together with a so-called thermal drive pump (40) for the conveyance of refrigerant from a cooling heat exchanger (42) to tanks (T1, T2) or the conveyance of the refrigerant from the tanks (T1, T2) to a heating heat exchanger (41).
